As you all know, at The Daily Brief, we have been writing about electronic components like semiconductors, PCBs, and a lot more for some time now. When we wrote about the manufacturing of printed circuit boards (PCBs), Murali Srinivasa from Lion Circuits replied. We thought it would be nice to learn from him about how PCBs work. See, everyone talks about chips, but every chip needs something to sit on, something to connect it to other components, something to carry electrical signals from one place to another. That something is a printed circuit board. Everything from your phone to your laptop, to your TV remote, and even the engine control unit in your car, has at least one PCB. The simplest way Murali explained it was through an analogy with a building's electrical system. You have a main control panel, bulbs on different floors, and you have wires running from the panel to each bulb. A PCB does essentially the same thing, except it shrinks the whole setup by a factor of a thousand or more. The wires become copper tracks etched onto a surface, the bulbs become LEDs or sensors, and the control panel becomes a semiconductor chip. But here's what surprised us. The PCB inside your phone is less a flat board with some tracks running across it, and more a skyscraper. Murali said that a typical smartphone PCB is about one millimetre thick, roughly the thickness of a credit card. But inside that one millimetre, there are fifty to sixty layers stacked on top of each other. Each layer is like a floor in a building, with its own copper tracks, its own electrical connections. A signal can start at the bottom and travel to the top through tiny plated holes that act like staircases between floors. So when you're holding your phone, you're holding a sixty-floor building compressed into the thickness of a credit card. Not all PCBs are sixty-layer skyscrapers, of course. There's a whole spectrum. Your TV remote has a simple single-layer board. Some devices use double-layer boards, with tracks on top and bottom. Then there are multi-layer boards with four, six, eight, or twelve layers, the kind you find in car engine control units. And at the extreme end, you have phones and smartwatches with fifty or sixty layers. The more layers you have, the harder it is to make. When you're making a multi-layer board, you manufacture each inner layer separately, then press them all together like a sandwich. After that, you drill holes through the stack to connect the different floors. The problem is that once you've pressed all the layers together, you can't see the inner ones anymore. You're drilling blind, trusting that everything aligned perfectly. And how perfect does it need to be? He told me that if a layer shifts by just fifty microns during pressing, the entire board becomes scrap. Fifty microns is half the thickness of a human hair. You're building something with sixty floors, compressing it into one millimetre, and if any floor is off by half a hair's width, the board goes in the bin. This kind of precision is why PCB manufacturing isn't just about having the right machines. He used a phrase that stuck with me: tribal knowledge. It's the knowledge that exists only within people who do the work, year after year. It's not in any manual, it's not taught in college, and it can't be bought from a consultant. It lives in the hands of people who've spent years figuring out why the same machine, same chemical, same process produces different results on different days. He said if someone gave him ten thousand crore rupees today and asked him to build a jet engine in six months, the same timeline Boeing uses, it would be impossible. Not because of the money, but because that kind of knowledge doesn't transfer through bank accounts. It transfers through people, slowly, over the years. This is also why China is so far ahead of us in PCBs. In the early 2000s, American companies didn't just move orders to China. They moved engineers who taught Chinese factories how to build things. The tribal knowledge that had accumulated over decades got transferred, person by person. India, focused on IT and services, missed that transfer almost entirely. There's a lot more in our conversation - how India was actually ahead of China in the 1980s, why we became a net importer of copper, what it takes to go from making 150-micron tracks to 25-micron tracks, and what needs to happen for India to build a real PCB industry. If you have made it this far, you will enjoy the full conversation for sure.

Another chilly evening in Western Europe, as Elliot Williams is joined this week by Jenny List to chew the fat over the week's hacks. It's been an auspicious week for anniversaries, with the hundredth since the first demonstration of a working television system in a room above a London coffee shop. John Logie Baird's mechanically-scanned TV may have ultimately been a dead-end superseded by the all-electronic systems we all know, but the importance of television for the later half of the 20th century and further is beyond question. The standout hacks of the week include a very clever use of the ESP32's WiFi API to detect people moving through a WiFi field, a promising open-source smartphone, another ESP32 project in a comms system for cyclists, more cycling on tensegrity spokes, a clever way to smooth plaster casts, and a light sculpture reflecting Wi-Fi traffic. Then there are a slew of hacks including 3D printed PCBs and gem-cut dichroic prisms, before we move to the can't-miss articles. There we're looking at document preservation, and a wallow in internet history with a look at the Netscape brand. As usual all the links you need can be found over on Hackaday, so listen, and enjoy!
In this important and timely presentation on "The Effects of Toxins on Mental Health," naturopathic physician and environmental medicine pioneer Dr Joe Pizzorno reveals how the global rise in mental health disorders parallels a dramatic increase in human exposure to toxic chemicals. He explains that toxins now permeate our food, water, air, household environments, and even medical care – while the nutrients that once protected us from these chemicals have simultaneously declined in the modern diet. This combination, he shows, has created ideal conditions for brain dysfunction, neurodegeneration and mood disorders worldwide. Dr Pizzorno – founding president of Bastyr University, co-author of Clinical Environmental Medicine and The Toxin Solution, and one of the world's leading voices in science-based natural medicine – draws on decades of research, clinical practice and large-scale human data to demonstrate that environmental toxins are now major drivers of neurological and psychiatric illness. He outlines how specific contaminants, including arsenic, pesticides, industrial chemicals, persistent organic pollutants (POPs), mercury and commonly used medications, damage the brain through mitochondrial dysfunction, oxidative stress, glutathione depletion, microglial activation and impaired apoptosis. In this deeply informative and practical session, Dr Pizzorno explains how clinicians and patients can meaningfully reduce toxic exposure and support detoxification through diet, lifestyle and environmental choices. By correcting nutritional deficiencies, decreasing total toxic load and improving the body's natural elimination pathways, he shows that biomarkers of oxidative and toxic burden can improve – and so can long-term brain health. In this episode, you will learn: Why the global epidemic of mental disorders aligns closely with rising exposure to neurotoxins and falling intake of protective nutrients. Which environmental toxins are strongly associated with dementia, cognitive decline, depression, ADHD, autism and Parkinson's disease. Why arsenic, particularly from contaminated water and food, is one of the most damaging neurotoxins linked to Alzheimer's disease, dementia and major cancers. How pesticides, PCBs and contaminated fish contribute to neurodegeneration and psychiatric symptoms. Why commonly used prescription and over-the-counter medications can act as neurotoxins and increase the risk of dementia. How toxins harm the brain through mitochondrial damage, oxidative stress and glutathione depletion. Why food is the single largest source of toxic exposure, followed by water, household chemicals, personal-care products and indoor air. Practical ways to reduce exposure at home, including air filtration, choosing cleaner products and improving food quality. How increasing dietary fibre and colourful plant foods supports toxin elimination and protects brain function. Why supporting glutathione and detoxification pathways – and maintaining these habits over time – can lower oxidative burden and improve long-term mental health.

In this fascinating episode, we dive deep into the world of agile hardware development with Gregor Gross, a civil engineer who runs Alpha-board, a PCB design service company in Berlin, Germany. Gregor shares his unique perspective on applying agile principles to hardware projects, where you can't just hit compile and get a new increment.We explore the practical challenges of agile hardware development, from structuring contracts differently to breaking complex PCBs into testable modules and shields. Gregor discusses the importance of mixed hardware-software teams, the role of automated documentation, and why his engineers resist pair programming despite its proven benefits. The conversation also touches on the cultural barriers to adopting agile practices in traditional hardware companies and the innovative approaches needed to make agile hardware development work in a service provider context.Key Topics[02:30] Introduction to Alpha-board and agile hardware development services[05:15] Defining agile principles: functionality-focused development and prioritization[12:45] Contract challenges: moving from fixed-price to hourly service contracts[18:20] Practical agile hardware: breaking PCBs into testable modules and shields[25:10] Mixed teams and automated documentation for hardware-software collaboration[32:40] The pair programming experiment: better results but team resistance[38:55] Customer expectations and the need for end-user access in agile projects[44:30] Version control and Git integration for hardware design workflowsNotable Quotes"We are probably the only service provider in Germany that offers agile hardware development because I don't see so many people speaking about it." — Gregor Gross"Software is soft, hardware is hard. I was waiting to say that." — Gregor Gross"My experience from pairing was they work harder. They feel like they observe themselves... but there wasn't any mistakes. And actually they themselves said they were surprised by how much they did because they did more than twice what they expected." — Gregor Gross"It's better to have different shields and modules that have some of the functionality. And so you can start iterating through these functionalities and test them." — Gregor GrossResources MentionedAlpha-board - Gregor's PCB design and agile hardware development service companyZephyr OS - Real-time operating system mentioned for prototyping with sample boardsKiCad - Open source EDA tool recommended for mixed teams and transparencyAndrew Greenberg's KiCon Presentation - Presentation on schematic style guides for better readability You can find Jeff at https://jeffgable.com.You can find Luca at https://luca.engineer.Want to join the agile Embedded Slack?

On paper, fish have everything required to be an excellent staple to many diets. They're rich in protein, vitamins, trace elements, long-chain omega-3 fatty acids, and aren't too high in calories. The only downside is that fish live in an increasingly polluted environment. What with heavy metals and plastic waste invading the oceans, more and more people are concerned about the pitfalls of eating fish. After all, they can be contaminated by chemical pollutants such as PCBs, methylmercury, or dioxins. These endocrine disruptors can have very harmful effects such as causing neurological disorders or forms of cancer. Furthermore, food derived from fish flesh is also likely to be contaminated with microorganisms such as bacteria and parasites. Should we stop eating fish then? Should I avoid any other types of fish? In under 3 minutes, we answer your questions! To listen to the latest episodes, click here: What is Sisu? What does Mercury in retrograde mean?

A crowded server board with ten thousand parts doesn't forgive sloppy inspection—and neither do pricey GPUs and chiplets. From the floor of Productronica in Munich, we dig into how automated optical inspection keeps advanced packages honest once they hit the PCB line, where solder quality, coplanarity, and sheer component variety can make or break yield. Vidya Vijay from Nordson Test & Inspection joins us to unpack why AOI remains the fastest path to actionable insight, when X‑ray is the smarter choice, and how new sensor design changes the game for reflective, high‑mix assemblies.We explore the real pain points engineers face today: shiny dies that confuse cameras, BGAs packed with I/O where hidden defects hide under the body, and miniature passives that crowd tight keep‑outs. Vidya explains how three‑phase profilometry creates true 3D height maps by projecting fringe patterns and reading them from multiple angles, enabling precise checks for corner fill, underfill, and coplanarity. We also get into multi‑reflection suppression, Nordson's approach to filtering glare and ghost images so the system sees the joint, not the noise. With true RGB on side cameras and higher resolution, AOI can now pick out tiny solder balls and subtle surface issues at speed—fuel for stronger AI autoprogramming and more reliable defect classification.If throughput is king, data is queen. We talk about closing the loop from inspection back to the line to prevent bad lots—flagging stencil drift, placement offsets, and paste issues before they explode into scrap. Then we spotlight Nordson's launched SQ5000 Pro: faster cycle times, a wider field of view, and configurable 7 µm or 10 µm sensors designed for modern PCBA demands. Whether you're chasing yield on high‑value GPUs or balancing AOI with AXI on dense boards, this conversation offers a practical roadmap for choosing the right tool, tackling reflectivity, and using insight to drive predictable quality.Nordson Test and Inspection Delivering best-in-class test, inspection, and metrology solutions for semiconductor applications.

Send us a textEver wonder how a pumpkin could help clean a toxic field—and why your dog might boost your mood as much as a wedding ring? We unpack both, starting with fresh research from Kobe University that reveals how a small amino acid tag on major latex-like proteins pushes pollutants into plant sap. That single routing decision explains why some gourds move stubborn chemicals like PCBs all the way to their fruits, illuminating both the promise of phytoremediation and the risk if contaminated soils meet our dinner tables. We talk practical implications for agriculture too—how breeders and bioengineers could tune protein binding and secretion to create safer crops while using separate plots for soil cleanup.Then we turn to the science of happiness with a study that estimates cats and dogs can elevate life satisfaction on par with being married or seeing friends often. The researchers used instrumental variables to tease causation, not just correlation, and the findings match what many of us feel: pets reduce loneliness, add structure, and get us moving. We dig into the nuance—pets offer deep comfort and presence, while people bring complex emotional and intellectual support—and why the best lives layer both.If this mix of plant science, pet happiness, and real-world tips resonates, follow the show, share it with a friend, and leave a quick review so more curious listeners can find us.Here is the link to all our socials and stuff!!!Support the showFor Science, Empathy, and Cuteness!Being Kind is a Superpower.

Lawrence M. Schell is a Distinguished Professor in the Department of Anthropology and the College of Integrated Health Sciences at the University at Albany, SUNY, with a joint appointment in the Department of Epidemiology and Biostatistics. His research explores the interrelationship between biology and culture, with a particular focus on how contemporary urban environments shape human health and development. Dr. Schell's early work examined noise as a form of urban stress, investigating its effects on prenatal and postnatal growth. He later expanded his research to include pollutants such as polychlorinated biphenyls (PCBs) and lead, situating these exposures within the broader context of urban adaptation and health disparities. The study of lead exposure in Albany, NY, examined its influence on child physical and cognitive development, with attention to maternal nutrition and other factors that affect the transfer of lead from mother to fetus. In partnership with the Akwesasne Mohawk Nation he has recently completed three major projects. The first examined how PCBs that were used in manufacturing affect physical and sexual development during adolescence. His second project followed up the adolescents in project 1 to learn how exposure had influenced their transition into adulthood. The third project, also conducted with the Akwesasne community, explored how environmental pollutants may impact reproductive health and fertility among women. Through this work, Dr. Schell highlights the urban environment as a critical frontier for human adaptation, emphasizing the challenges posed by pollution, stress, and other features of modern city life while recognizing that these challenges are inequitably distributed in society. In 2004 Schell established a research center at Albany with NIH support to grow research on health disparities. Continued NIH support culminated in an endowment grant that will support the center and the development of health disparities research for many years to come. ------------------------------ Contact the Sausage of Science Podcast and the Human Biology Association: Facebook: facebook.com/groups/humanbiologyassociation/, Website: humbio.org, Twitter: @HumBioAssoc Chris Lynn, Co-Host Website: cdlynn.people.ua.edu/, E-mail: cdlynn@ua.edu, Twitter:@Chris_Ly Courtney Manthey, Guest-Co-Host, Website: holylaetoli.com/ E-mail: cpierce4@uccs.edu, Twitter: @HolyLaetoli Anahi Ruderman, SoS Co-Producer, HBA Junior Fellow, E-mail: ruderman@cenpat-conicet.gob.ar
Hackaday Editors Tom Nardi and Al Williams spent the weekend at Supercon and had to catch up on all the great hacks. Listen in as they talk about their favorites. Plus, stick around to the end to hear about some of the highlights from their time in Pasadena. If you're still thinking about entering the Component Abuse Contest, you're just about out of time. Need some inspiration? Tom and Al talk about a few choice entries, and discuss how pushing parts out of their comfort zone can come in handy. Do you make your own PCBs? With vias? If you have a good enough laser, you could. Or maybe you'd rather have a $10 Linux server? Just manage your expectations. The guys both admit they aren't mechanical geniuses and, unlike [4St4r], aren't very good at guessing sounds either. They round up with some 3D printing projects and a collection of quick hacks.
Sitting down at FermionX with Managing Director Will Patrick, we explore how a third-generation MD took a family electronics manufacturer from tribal knowledge to a data-first operation that customers can see, trust, and scale with.We start with the lineage—granddad's silkscreen craft evolving to PCBs, then assembly—and why honoring that service and customer focussed ethic made the transformation stick. Then we lift the hood on the digital rebuild: a modern MES for full traceability, powerful dashboards for top-level clarity, and smarter quality tooling including Koh Young's KSMART and Luminovo. The goal wasn't technology for its own sake; it was a single source of truth where every action leaves a data point and every decision gets faster, cleaner, and easier to audit.From there, we talk growth. By redesigning processes and floor layout, Will has created headroom to push from around £10M to £25M without stacking overhead. We break down how visibility wins contracts in the EMS world, why customers value shared dashboards and live traceability, and how a long-term, 20–30 year plan changes which investments make sense today. We also get practical about AI: exception-driven MRP alerts, machine feedback loops, and agentic systems that surface the one issue that will derail tomorrow—after, and only after, the data foundation is solid.If you care about scaling a contract manufacturer without losing your soul—or your margins—you'll find concrete steps here: where to start with MES, how to drive cultural adoption, which metrics to watch, and how to stitch tools together so operators move faster, not slower.

Monsanto has settled with more than 200 people in Monroe, Washington, who were exposed to PCBs -- toxic chemicals once produced by the company. Students, parents and staff at the Sky Valley alternative school in Snohomish County, had filed lawsuits against Monsanto starting in 2018, after reporting significant illnesses. The amount of the settlement has not been revealed, but it looks to possibly be the largest settlement over PCB exposure at a single site.

[01:02:09] Conservatives Back Martial LawOpening monologue criticizes conservatives for supporting Trump's talk of deploying troops in U.S. cities, linking it to the Pentagon's long-term planning for urban control. [01:05:31] Prohibition, Cartels & TerrorComparison of alcohol prohibition to the drug war; warns that attacking Mexican cartels militarily could spark terrorism inside American cities and provide cover for martial law. [01:12:29] Election Rigging & GerrymanderingDiscussion of how both parties manipulate elections through gerrymandering and voting controls; frames Trump as a Pentagon puppet in a larger plan of urban militarization. [01:20:48] Conservatives Cheer MilitarizationChicago carjacking victim opposed National Guard deployment; conservatives attacked her online, showing how Trump has shifted the right to embrace authoritarian solutions. [01:29:46] Normalizing Martial LawAnalysis of how deploying troops in D.C. and other cities is “predictive programming” to normalize military presence and condition officials and citizens for broader martial law. [01:45:21] Democrats Only OppositionClosing reflections argue conservatives have abandoned constitutional limits, leaving only Democrats to oppose Trump's martial law plans—though they oppose for the wrong reasons, focusing only on partisan power. [02:19:39] Texas “Big Beautiful Map” & Election RiggingDiscussion of Texas Senate passing a gerrymandered redistricting bill, Trump pushing to ban mail-in ballots and voting machines, and how both parties manipulate elections.

What happens when science and policy collide — and how can we prepare for the environmental health challenges ahead? In part two of our series with Dr. Peter Thorne, University of Iowa Distinguished Chair and Professor of Occupational and Environmental Health, we dig into persistent pollutants, climate change, and the future of science-informed policymaking. In this episode, you'll learn about: • The risks of PCBs, PFAS, and other “forever chemicals” • How communities weigh costs and health risks in decisions like school renovations • The challenges of science advisory boards in an era of political polarization • Climate-related disasters — from wildfires to hurricanes — and their health consequences • Why better science communication and stronger policy action are urgently needed This conversation shows how today's public health challenges extend beyond the lab, into policy decisions that will shape the lives of future generations.

Welcome to the PRESSURISED version of episode 61, just the science, none of the waffle PRESSURISED: Trench nutrient cycling with Ronnie N. Glud | The Deep Sea Podcast | Episode 61 Guest Interview: Nutrient cycling in the hadal trenches (6 to 11 km) and the crucial role they play in global element cycling. Professor Ronnie N. Glud, a leading biochemist and Director of the Danish Centre for Hadal Research (HADAL) talks us through how the trenches, once thought to be barren, are actually "dynamic deep-sea hotspots with intensified microbial activity and diversity". Learn about: How hadal trenches act as "depocenters" for organic material, leading to microbial activity that's 2 to 6 times higher than in adjacent abyssal sites. The surprising diversity of microbial "generalists" that easily adapt to the immense pressure and low temperatures, aided by viruses that facilitate "horizontal gene transfer". The return of full anaerobic diagenetic processes (like sulphate reduction and anammox) in trench sediments, making them significant sinks for fixed nitrogen. The role of marine snow and seismic activity in efficiently transporting organic matter and, surprisingly, pollutants like PCBs and heavy metals to these remote depths. Why these trenches are not isolated environments but are highly connected to surface ocean processes, even responding to climate-driven changes in primary production. We also have a surprise blobfish guest! Support the show The podcast is self-sustaining (just) thanks to our lovely listeners. Thom and Alan take no money for the show.

In this two-part interview, Dr. Peter Thorne, University of Iowa Distinguished Chair and Professor of Occupational and Environmental Health and a leading expert in toxicology, provides an in-depth overview of how the federal government regulates chemicals in food, water, and air. Key points: • The EPA and FDA are science-based organizations that interpret laws passed by Congress and apply the best available science to make regulatory decisions aimed at protecting human health and the environment. • The EPA's Science Advisory Board provides independent, non-partisan oversight to ensure the agency's decisions are grounded in scientific evidence. • Chemical regulations are dynamic, with compounds like Red Dye No. 3 and inorganic arsenic being re-evaluated as new scientific data emerges. • The precautionary principle guides regulators to err on the side of safety when the evidence suggests a chemical may pose health risks, even in the absence of definitive human studies. • Replacing problematic chemicals with safer alternatives can facilitate regulatory action, though the availability of substitutes should not be the primary driver of these decisions. • Persistent organic pollutants like PCBs and PFAS pose complex public health challenges due to their ubiquity and long-lasting environmental presence, underscoring the need for continued research and policy responses.

Rico Knapper is the CEO of Pailot and loves PCBs shopfloors. Why? Because his AI based solution outperforms other approaches. We met him at Siemens.
In this powerful episode, co-hosts Santana and Haley sit down with Chief Beverly Cook of the Saint Regis Mohawk Tribe, to discuss the toxic legacy of industrial contamination along the St. Lawrence River. They explore how pollution from General Motors, Reynolds Metals, and Alcoa Aluminum led to dangerously high levels of PCBs in the water—and how that contamination ultimately made its way into women's breast milk. Chief Cook shares powerful insight on the intergenerational impacts of environmental harm and the urgent need for trauma informed practices & responses.
Dr. Andres Cardenas, from the Department of Epidemiology and Population Health at Stanford University, joins host Dr. Evgeniy Galimov to discuss a research paper he co-authored in Volume 17, Issue 2 of Aging (Aging-US), titled “Exposome-wide association study of environmental chemical exposures and epigenetic aging in the National Health and Nutrition Examination Survey.” DOI - https://doi.org/10.18632/aging.206201 Corresponding author - Andres Cardenas - andresca@stanford.edu Video interview - https://www.youtube.com/watch?v=A1I6qoVwkfM Longevity & Aging Series - https://www.aging-us.com/longevity Abstract Epigenetic clocks can serve as pivotal biomarkers linking environmental exposures with biological aging. However, research on the influence of environmental exposures on epigenetic aging has largely been limited to a small number of chemicals and specific populations. We harnessed data from the National Health and Nutrition Examination Survey 1999-2000 and 2001-2002 cycles to examine exposome-wide associations between environmental exposures and epigenetic aging. A total of 8 epigenetic aging biomarkers were obtained from whole blood in 2,346 participants ranging from 50-84 years of age. A total of 64 environmental exposures including phthalates, metals, pesticides, dioxins, and polychlorinated biphenyls (PCBs) were measured in blood and urine. Associations between log2-transformed/standardized exposure measures and epigenetic age acceleration (EAA) were assessed using survey-weighted generalized linear regression. A 1 standard deviation (SD) increase in log2 serum cadmium levels was associated with higher GrimAge acceleration (beta = 1.23 years, p = 3.63e-06), higher GrimAge2 acceleration (beta = 1.27 years, p = 1.62e-05), and higher DunedinPoAm (beta = 0.02, p = 2.34e-05). A 1 SD increase in log2 serum cotinine levels was associated with higher GrimAge2 acceleration (beta = 1.40 years, p = 6.53e-04) and higher DunedinPoAm (beta = 0.03, p = 6.31e-04). Associations between cadmium and EAA across several clocks persisted in sensitivity models adjusted for serum cotinine levels, and other associations involving lead, dioxins, and PCBs were identified. Several environmental exposures are associated with epigenetic aging in a nationally representative US adult population, with particularly strong associations related to cadmium and cotinine across several epigenetic clocks.

This week at the desk, we worked on getting more small hardware boards done. We revised our 1.5" transparent OLED breakout (oops, pins were swapped), designed breakouts for sensors like the AS5600 (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/AS5600-ASOM/8250257) and STHS34PF80 (https://www.digikey.com/en/products/detail/stmicroelectronics/STHS34PF80/13187390), and updated the NAU7802 (https://www.digikey.com/en/products/detail/nuvoton-technology-corporation-of-america/NAU7802SGI/4929384) to have both ADC ports available. We're also working on another stepper motor driver, since the TMC2209 breakout (https://www.adafruit.com/product/6121) was a big hit. We wrapped and sent out the Triple-output Active Shifting RGB Matrix Bonnet (https://blog.adafruit.com/2025/02/28/triple-matrix-bonnet-makes-big-bright-displays/). Then we finally had a little time to get back into bigger projects, like Fruit Jam, which we re-picked-up! This week we focused on implementing the ESP32-C6 Wi-Fi co-processor, which needed a bit of rework, but now we've got rev C prototype PCBs on the way. ----------------------------------------- Visit the Adafruit shop online - http://www.adafruit.com LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------

Can fish oil really transform your health? In this episode, I sit down with Dr. Charles Sefcik, a board-certified chiropractic neurologist and certified clinical nutritionist, to explore one of the most powerful and underrated tools in functional medicine: omega-3s. We break down how EPA and DHA support your brain, hormones, metabolism, and inflammation pathways—and why most people aren't getting nearly enough from food alone. We also share what to look for in a quality fish oil supplement, how to avoid common pitfalls like oxidation and poor sourcing, and why testing your fatty acid levels can make all the difference. Packed with clinical insight and real-world advice, this conversation is a must-listen for anyone looking to use nutrition as a foundation for long-term health Key Takeaways: Omega-3 fatty acids are critical for cell membrane fluidity, reducing inflammation, and enhancing cognitive function. Fish oil quality matters; choose supplements devoid of contaminants like mercury and PCBs and go for third-party certified products. Omega-3s have a profound impact on reducing neuroinflammation and supporting hormone function, influencing overall brain health and longevity. Regular testing, like the OmegaQuant, can provide valuable insights into your fatty acid balance, guiding effective supplementation and dietary adjustments. Combining omega-3 supplements with a healthy diet and lifestyle can prevent chronic diseases, promote muscle synthesis, and ensure optimum brain health.

It might not be Pi Day anymore, but Elliot and Dan got together for the approximately 100*Pi-th episode of the Podcast to run through the week's coolest hacks. Ultrasound seemed to be one of the themes, with a deep dive into finding bugs with sonar as well as using sound to cut the cheese -- and cakes and pies, too. The aesthetics of PCBs were much on our minds, too, from full-color graphics on demand to glow-in-the-dark silkscreens. Is automation really needed to embed fiber optics in concrete? Absolutely! How do you put plasma in a bottle? Apparently, with kombucha, Nichrome, and silicone. If you need to manage your M:TG cards, scribble on the walls, or build a mechanical chase light, we've got the details. And what exactly is a supercomputer? We can't define it, but we know one when we see it. Check out all the links over at Hackday!
This week's EYE ON NPI is a NAND in the HAND, it's ISSI Serial NAND Flash chips (https://www.digikey.com/en/product-highlight/i/issi/serial-nand-flash) available in a variety of sizes and footprints. These are great options for folks that need more data storage on their PCBs, but don't necessarily want an SD card. DigiKey has a selection of 1Gbit and 2Gbit chips, so you have tons of storage for data logs, images, recordings, or even filesystems. And the price is great, you'll pay much less per byte when buying NAND flash There's plenty of times you'll need to access non-volatile memory on your microcontroller: graphics or audio files for a user interface, maps or almanac data for telemetry, sensor or usage logs, interpreted code scripts, firmware updates, security certificates, etc. these files are too big to be stored in simple EEPROM chips (https://www.digikey.com/short/0rf9t7qb) that max out at a few kB. The next step up is to use NOR Flash (https://www.digikey.com/short/jfp3bvph) - you can get up to 256 Megabytes in size! (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS25LP02GJ-RHLE/24617385) Compared to EEPROM which comes in 1-Wire, I2C or SPI, you definitely have to use an SPI interface for NOR Flash. It's also possible on many chips to have 4-bit-at-a-time QSPI or even 8-bit OSPI interfacing for fast reads. And that's the thing that's really nice about NOR: instant reads of any byte anywhere in memory just like EEPROM. Unlike EEPROM you can't write just one byte at a time anywhere in the storage, you have to write 'page' and erase a 'sector' at a time - each page tends to be about 256 bytes, a sector is often 4KB. That means if you want to update a file, you'll need to read the whole 4K block into a memory cache, change the bytes you want to, then erase and re-write the block out. The good news though is once you write out a page, you can pretty much assume it will stay for many years: there's rarely corrupted data in NOR flash. And, although erasing and writing is a bit of a pain, the instant-access means NOR is great for 'XIP' or other dynamic memory access. If NOR is so great, why bother with NAND? One is cost: a 2MB NOR chip isn't too bad about 45 cents in quantity (https://www.digikey.com/short/zff49fb7) but once you get to the biggest 256 MB ones (https://www.digikey.com/short/vffmp583) the pricing gets high pretty quickly: $15 in tray quantities. Considering you can get a 64G SD card for that price, NOR isn't very cost effective. Second is sizing: if you want 1GB for large files, it just isn't available. For that kind of density you need NOR flash. NAND flash is the kind of flash you get when you buy a USB key or microSD card, although those have USB or SDIO interface chips (https://www.bunniestudios.com/blog/2013/where-usb-memory-sticks-are-born/) that are wire bonded to the NAND flash chips. You get a lot more for the price: instead of $15 for 256MB NOR, its $3 (https://www.digikey.com/short/r77p0922). You also don't need more pins! We always thought that NAND flash required a lot of pins since it comes in 48-TSSOP (https://www.digikey.com/short/8zqbmw31) but turns out that you can get it in a QSPI 8-pin format. That makes it easy to integrate without needing an 8-bit wide memory controller. However, the architectural decisions that give ISSI NAND (https://www.digikey.com/short/jtp8ppdb) the massive size & low cost that we love also make it more complex to use than NOR flash. For one, you can no longer get random access to any byte you like. Instead, an entire page must be read at once into a 2176-byte cache, and then can be accessed. This is fine for most uses except we can't use XIP anymore and there are probably some memory access use cases that don't work nearly as nicely. Also that high density means that bits are more likely to go 'bad' and flip. While you can sorta-kinda get away with not doing error correction or wear leveling on NOR, you absolutely must do error correction and wear leveling on NAND! ISSI includes a simple multi-bit ECC system that can handle repairing up to 8 bits per 2176-byte page. And, every time there's ECC errors, you will need to 'refresh/rewrite' the data to clean it up. That refresh counts against the 60K or 100K write cycle - you are more likely to need wear-level management, even if you don't expect to write that often. Basically, check if your microcontroller SDK has a NAND controller library (https://github.com/D-Buckingham/NAND_flash) that can manage this all for you. So, if you need to level up your storage, with easy-to-use SPI or QSPI-interface, ISSI has many NAND (https://www.digikey.com/en/product-highlight/i/issi/serial-nand-flash) options to let you quickly and inexpensively add 1 or 2 gigabits of non-volatile memory with built in ECC support and block cache. DigiKey will be stocking them shortly, sign up (https://www.digikey.com/short/jtp8ppdb) to be notified when they drop into stock mid-next month!
This week, we were all over the place with a bunch of different designs and experiments. After last week's analysis of the TLV320DAC3100, we made some updates to the design and re-booked prototype PCBs. We also designed a triple-matrix bonnet: with our latest work on getting HUB75 RGB matrices working on the Raspberry Pi 5, we can now do matrix control on the latest Pi 5 chip. But we're limited by the RP1 chip, so to get big displays going, we'll need multiple strands—these don't use significantly more bandwidth because half of the pins are shared. Finally, we ended the week by getting another older prototype working: the SAM-M8Q is an entry-level all-in-one GPS from u-blox. It comes with both UART and I2C interfaces, plus a built-in antenna, so it's ready to go out of the box. The NMEA interface is trivial, but we also wanted to try out the UBX interface, and thankfully, Claude 3.7 was able to vibe-code it for us in a jiffy.

Orca mourns second calf since 2018 in a devastating report that J35 was seen floating her dead calf on January 1st, 2025. In this episode of the How to Protect the Ocean podcast, host Andrew Lewin discusses the tragic story of J35, a Southern Resident Orca, who lost her second calf, J61, shortly after its birth. The episode highlights several critical factors contributing to the high mortality rate of orca calves in this endangered population, which currently numbers only 73 individuals. Reasons for Calf Mortality: Food Scarcity: The primary prey of the Southern Resident Orcas, Chinook salmon, is in decline. The orcas rely exclusively on this species for sustenance, and with only a 20% survival rate for calves, the lack of adequate food supply is a significant concern. The orcas need a sufficient quantity of Chinook salmon to support their growth and health, especially during the early stages of life. Chemical Contamination: Orcas are among the most contaminated marine mammals due to bioaccumulation of toxins such as PCBs and DDT. These chemicals can impair reproductive and immune functions, potentially affecting the health of calves from birth. The presence of these toxins in the environment may contribute to the inability of calves to survive past their first year. Environmental Disturbances: Factors such as vessel noise and pollution disrupt the orcas' habitat, further complicating their survival. Increased shipping traffic and climate change exacerbate these issues, leading to a more challenging environment for the orcas. Reproductive Challenges: The Southern Resident Orcas are a long-lived species that take time to reach sexual maturity. With a low calf survival rate, the population struggles to maintain its numbers, especially as older individuals begin to pass away. The episode emphasizes the urgent need for conservation efforts, including habitat restoration and pollution control, to improve the chances of survival for orca calves and the overall health of the Southern Resident Orca population.
