Over time, they transitioned to custom circuit boards to meet the specific demands of automating gardening tasks like seed planting, watering, and weeding, highlighting the tradeoffs between speed to market and long-term hardware optimization.The conversation unpacks the complexity of FarmBot's “stack,” which integrates cloud-based software, a web app, a message broker, a Raspberry Pi running a custom OS, and firmware on both Arduino and auxiliary chips for real-time feedback. This layered approach is crucial for precision in an unpredictable outdoor environment where mechanical errors could damage growing plants.Aronson emphasizes that being open source isn't enough; to be genuinely useful, projects must provide extensive, accessible documentation and export files in open, affordable formats. Without this, open source risks being a hollow promise for most users, especially in hardware where barriers to modification are higher.They explore the solarpunk potential of FarmBot, imagining a future where growing food at home is as effortless as using a washing machine. By turning gardening into an automated process, FarmBot enables people to produce fresh vegetables without needing expertise, offering resilience against industrial food systems reliant on monoculture and long supply chains.Aronson points out that while FarmBot isn't designed for industrial agriculture, its modularity allows it to support niche commercial use cases, like automating seedling production in cleanroom environments. This adaptability reflects the broader vision of empowering both individuals and small operations with accessible automation tools.The episode highlights user creativity enabled by FarmBot's open hardware, including custom tools like side-mounted mirrors for alternative camera angles and pneumatic grippers for harvesting. These community-driven innovations showcase the platform's flexibility and the value of encouraging experimentation.Finally, Aronson sees great potential for integrating AI, particularly vision systems and multimodal LLMs, to make FarmBot smarter—detecting pests, diagnosing plant health, and even planning gardens tailored to user goals like nutrient needs or event timelines, moving closer to a truly intelligent gardening companion.

This show has been flagged as Explicit by the host. Overview Several years ago I wrote a Bash script to perform a task I need to perform almost every day - find the newest file in a series of files. At this point I was running a camera on a Raspberry Pi which was attached to a window and viewed my back garden. I was taking a picture every 15 minutes, giving them names containing the date and time, and storing them in a directory. It was useful to be able to display the latest picture. Since then, I have found that searching for newest files useful in many contexts: Find the image generated by my random recipe chooser, put in the clipboard and send it to the Telegram channel for my family. Generate a weather report from wttr.in and send it to Matrix. Find the screenshot I just made and put it in the clipboard. Of course, I could just use the same name when writing these various files, rather than accumulating several, but I often want to look back through such collections. If I am concerned about such files accumulating in an unwanted way I write cron scripts which run every day and delete the oldest ones. Original script The first iteration of the script was actually written as a Bash function which was loaded at login time. The function is called newest_matching_file and it takes two arguments: A file glob expression to match the file I am looking for. An optional directory to look for the file. If this is omitted, then the current directory will be used. The first version of this function was a bit awkward since it used a for loop to scan the directory, using the glob pattern to find the file. Since Bash glob pattern searches will return the search pattern when they fail, it was necessary to use the nullglob (see references) option to prevent this, turning it on before the search and off afterwards. This technique was replaced later with a pipeline using the find command. Improved Bash script The version using find is what I will explain here. function newest_matching_file { local glob_pattern=${1-} local dir=${2:-$PWD} # Argument number check if [[ $# -eq 0 || $# -gt 2 ]]; then echo 'Usage: newest_matching_file GLOB_PATTERN [DIR]' >&2 return 1 fi # Check the target directory if [[ ! -d $dir ]]; then echo "Unable to find directory $dir" >&2 return 1 fi local newest_file # shellcheck disable=SC2016 newest_file=$(find "$dir" -maxdepth 1 -name "$glob_pattern" \ -type f -printf "%T@ %p\n" | sort | sed -ne '${s/.\+ //;p}') # Use printf instead of echo in case the file name begins with '-' [[ -n $newest_file ]] && printf '%s\n' "$newest_file" return 0 } The function is in the file newest_matching_file_1.sh , and it's loaded ("sourced", or declared) like this: . newest_matching_file_1.sh The '.' is a short-hand version of the command source . I actually have two versions of this function, with the second one using a regular expression, which the find command is able to search with, but I prefer this one. Explanation The first two lines beginning with local define variables local to the function holding the arguments. The first, glob_pattern is expected to contain something like screenshot_2025-04-*.png . The second will hold the directory to be scanned, or if omitted, will be set to the current directory. Next, an if statement checks that there are the right number of arguments, aborting if not. Note that the echo command writes to STDERR (using '>&2' ), the error channel. Another if statement checks that the target directory actually exists, and aborts if not. Another local variable newest_file is defined. It's good practice not to create global variables in functions since they will "leak" into the calling environment. The variable newest_file is set to the result of a command substitution containing a pipeline: The find command searches the target directory. Using -maxdepth 1 limits the search to the chosen directory and does not descend into sub-directories. The search pattern is defined by -name "$glob_pattern" Using -type f limits the search to files The -printf "%T@ %p\n" argument returns the file's last modification time as the number of seconds since the Unix epoch '%T@' . This is a number which is larger if the file is older. This is followed, after a space, by the full path to the file ( '%p' ), and a newline. The matching file names are sorted. Because each is preceded by a numeric time value, they will be sorted in ascending order of age. Finally sed is used to return the last file in the sorted list with the program '${s/.\+ //;p}' : The use of the -n option ensures that only lines which are explicitly printed will be shown. The sed program looks for the last line (using '$' ). When found the leading numeric time is removed with ' s/.\+ //' and the result is printed (with 'p' ). The end result will either be the path to the newest file or nothing (because there was no match). The expression '[[ -n $newest_file ]]' will be true if $newest_file variable is not empty, and if that is the case, the contents of the variable will be printed on STDOUT, otherwise nothing will be printed. Note that the script returns 1 (false) if there is a failure, and 0 (true) if all is well. A null return is regarded as success. Script update While editing the audio for this show I realised that there is a flaw in the Bash function newest_matching_file . This is in the sed script used to process the output from find . The sed commands used in the script delete all characters up to a space, assuming that this is the only space in the last line. However, if the file name itself contains spaces, this will not work because regular expressions in sed are greedy . What is deleted in this case is everything up to and including the last space. I created a directory called tests and added the following files: 'File 1 with spaces.txt' 'File 2 with spaces.txt' 'File 3 with spaces.txt' I then ran the find command as follows: $ find tests -maxdepth 1 -name 'File*' -type f -printf "%T@ %p\n" | sort | sed -ne '${s/.\+ //;p}' spaces.txt I adjusted the sed call to sed -ne '${s/[^ ]\+ //;p}' . This uses the regular expression: s/[^ ]\+ // This now specifies that what it to be removed is every non-space up to and including the first space. The result is: $ find tests -maxdepth 1 -name 'File*' -type f -printf "%T@ %p\n" | sort | sed -ne '${s/[^ ]\+ //;p}' tests/File 3 with spaces.txt This change has been propagated to the copy on GitLab . Usage This function is designed to be used in commands or other scripts. For example, I have an alias defined as follows: alias copy_screenshot="xclip -selection clipboard -t image/png -i \$(newest_matching_file 'Screenshot_*.png' ~/Pictures/Screenshots/)" This uses xclip to load the latest screenshot into the clipboard, so I can paste it into a social media client for example. Perl alternative During the history of this family of scripts I wrote a Perl version. This was originally because the Bash function gave problems when run under the Bourne shell, and I was using pdmenu a lot which internally runs scripts under that shell. #!/usr/bin/env perl use v5.40; use open ':std', ':encoding(UTF-8)'; # Make all IO UTF-8 use Cwd; use File::Find::Rule; # # Script name # ( my $PROG = $0 ) =~ s|.*/||mx; # # Use a regular expression rather than a glob pattern # my $regex = shift; # # Get the directory to search, defaulting to the current one # my $dir = shift // getcwd(); # # Have to have the regular expression # die "Usage: $PROG regex [DIR]\n" unless $regex; # # Collect all the files in the target directory without recursing. Include the # path and let the caller remove it if they want. # my @files = File::Find::Rule->file() ->name(qr/$regex/) ->maxdepth(1) ->in($dir); die "Unsuccessful search\n" unless @files; # # Sort the files by ascending modification time, youngest first # @files = sort {-M($a) -M($b)} @files; # # Report the one which sorted first # say $files[0]; exit; Explanation This is fairly straightforward Perl script, run out of an executable file with a shebang line at the start indicating what is to be used to run it - perl . The preamble defines the Perl version to use, and indicates that UTF-8 (character sets like Unicode) will be acceptable for reading and writing. Two modules are required: Cwd : provides functions for determining the pathname of the current working directory. File::Find::Rule : provides tools for searching the file system (similar to the find command, but with more features). Next the variable $PROG is set to the name under which the script has been invoked. This is useful when giving a brief summary of usage. The first argument is then collected (with shift ) and placed into the variable $regex . The second argument is optional, but if omitted, is set to the current working directory. We see the use of shift again, but if this returns nothing (is undefined), the '//' operator invokes the getcwd() function to get the current working directory. If the $regex variable is not defined, then die is called to terminate the script with an error message. The search itself is invoked using File::Find::Rule and the results are added to the array @files . The multi-line call shows several methods being called in a "chain" to define the rules and invoke the search: file() : sets up a file search name(qr/$regex/) : a rule which applies a regular expression match to each file name, rejecting any that do not match maxdepth(1) : a rule which prevents the search from descending below the top level into sub-directories in($dir) : defines the directory to search (and also begins the search) If the search returns no files (the array is empty), the script ends with an error message. Otherwise the @files array is sorted. This is done by comparing modification times of the files, with the array being reordered such that the "youngest" (newest) file is sorted first. The operator checks if the value of the left operand is greater than the value of the right operand, and if yes then the condition becomes true. This operator is most useful in the Perl sort function. Finally, the newest file is reported. Usage This script can be used in almost the same way as the Bash variant. The difference is that the pattern used to match files is a Perl regular expression. I keep this script in my ~/bin directory, so it can be invoked just by typing its name. I also maintain a symlink called nmf to save typing! The above example, using the Perl version, would be: alias copy_screenshot="xclip -selection clipboard -t image/png -i \$(nmf 'Screenshot_.*\.png' ~/Pictures/Screenshots/)" In regular expressions '.*' means "any character zero or more times". The '.' in '.png' is escaped because we need an actual dot character. Conclusion The approach in both cases is fairly simple. Files matching a pattern are accumulated, in the Bash case including the modification time. The files are sorted by modification time and the one with the lowest time is the answer. The Bash version has to remove the modification time before printing. This algorithm could be written in many ways. I will probably try rewriting it in other languages in the future, to see which one I think is best.

Hey Retro Fans!

In this episode of Beekeeping Today Podcast, we welcome an inspiring young voice in honey bee research—Atreya Manaswi, a high school senior and top 40 finalist in the 2025 Regeneron Science Talent Search. Atreya shares the fascinating journey that began with a fishing trip and led to a multi-year research project aimed at controlling one of the most damaging pests of honey bees: the small hive beetle. Working under mentorship from the USDA and University of Florida, Atreya developed a new organic bait based on the volatile compounds found in beer. He didn't stop there—he designed a solar-powered, 3D-printed trap equipped with LED sensors and a Raspberry Pi to count beetles automatically and predict future infestations using artificial intelligence. His bait-and-trap system could offer a cleaner, more sustainable, and reusable alternative to traditional beetle traps. Atreya also talks about his picture book The Bee Story, his outreach work with youth and beekeeping clubs, and his upcoming studies at Yale University. His dedication to pollinator health and science communication offers a hopeful glimpse into the future of bee research. Whether you're a beekeeper dealing with small hive beetles or just curious about next-gen solutions, you won't want to miss this conversation.

Container-based Linux distributions are gaining traction, especially for edge deployments that demand lightweight and secure operating systems. Talos Linux, developed by Sidero Labs, is purpose-built for Kubernetes with security-first features like a fully immutable file system and disabled SSH access. In a demo, Sidero CTO Andrew Rynhard and Head of Product Justin Garrison explained Talos's design philosophy, highlighting its minimalism and focus on automation. Inspired by CoreOS, Talos removes traditional tools like systemd and Bash, replacing them with machineD, a custom process manager written in Go.Talos emphasizes API-driven management rather than SSH, making Kubernetes cluster operations more scalable and consistent. Its design supports cloud, bare metal, Docker, and edge devices like Raspberry Pi. Kernel immutability is reinforced by ephemeral signing keys. Through Sidero's Omni SaaS, Talos nodes connect securely via WireGuard. The operating system handles all certificates and network connectivity internally, streamlining security and deployment. As Garrison notes, Talos delivers a portable API for “big iron, small iron—no matter what.”Learn more from The New Stack about Sidero Labs:  Is Cluster API Really the Future of Kubernetes Deployment? Choosing a Linux Distribution Join our community of newsletter subscribers to stay on top of the news and at the top of your game. https://thenewstack.io/newsletter/

Connor Rigby joins the Elixir Wizards to talk about Blue Heron BLE (Bluetooth Low Energy) support for Elixir apps. Blue Heron implements the BLE specs in pure Elixir, leveraging binary pattern matching and concurrent message processing to handle Bluetooth protocols. Unlike most solutions that require C ports or NIFs, Blue Heron runs entirely in user space, so it works seamlessly in both Nerves-based embedded projects and (eventually) desktop Elixir applications. We discuss how Nerves development differs from building Phoenix apps. Connor shares challenges he's experienced with hardware compatibility, where some chips only partially implement the spec, and he discusses the surprisingly deep (but sometimes incomplete) world of BLE device profiles. His tip for anyone entering the BLE space: read the official spec instead of trusting secondhand blog posts. Tools like Nerves LiveBook give you hands-on examples, so you can get a BLE prototype running on a Raspberry Pi and your phone in no time. Key topics discussed in this episode: Blue Heron origins and “bird” naming convention BLE vs. Bluetooth Classic: core differences Pure Elixir implementation—no C dependencies Binary pattern matching for packet parsing Hardware transport options: UART, SPI, USB, SDIO GenServer patterns in Nerves vs. Phoenix Linux requirement and power-consumption trade-offs GATT (Generic Attribute Table) implementation patterns SQLite integration for Nerves apps Hardware chip quirks and spec compliance Manufacturer-specific commands and workarounds BLE device profiles and spec gaps Security Management Profile (SMP) for encryption Device connection and pairing workflows Web vs. embedded development differences Where to get started: hardware recommendations and docs Links mentioned: https://github.com/ConnorRigby/ https://github.com/blue-heron/ https://nerves-project.org/ BLE (Bluetooth Low Energy) https://en.wikipedia.org/wiki/BluetoothLowEnergy https://developer.apple.com/ibeacon/ https://learnyousomeerlang.com/building-otp-applications Linux https://www.linux.org/ HCI (Host Controller Interface) https://en.wikipedia.org/wiki/Hostcontrollerinterface Circuits UART Library https://hexdocs.pm/circuitsuart/readme.html SPI (Serial Peripheral Interface) https://github.com/elixir-circuits/circuitsspi SDIO (Secure Digital Input Output https://en.wikipedia.org/wiki/SDIO Raspberry Pi https://www.raspberrypi.com/ Coral SoM Dev Board https://coral.ai/products/dev-board/ BeagleBone Single-Board Linux Computer https://www.beagleboard.org/boards/beaglebone-black https://www.bluetooth.com/bluetooth-resources/intro-to-bluetooth-gap-gatt/ Genservers https://hexdocs.pm/elixir/1.12/GenServer.html https://hexdocs.pm/ecto/Ecto.html https://github.com/elixir-sqlite/ectosqlite3 https://github.com/nerves-livebook/nerveslivebook Special Guest: Connor Rigby.

Send us a textWhat does it take to write the books that build the backbone of the networking industry? In this energetic conversation with Jason Gooley, Technical Evangelist at Cisco and author of numerous certification guides, we dive into the fascinating world of technical education and the art of making complex networking concepts accessible to learners.Jason shares his remarkable journey from networking novice who once believed the myth that "CCIEs make more than the president" to becoming the author selected to take over the iconic CCNA certification guides from Wendell Odom after his 23-year, 10-edition legacy. The responsibility is enormous—with Cisco's Network Academy having certified 17 million professionals and aiming for another 25 million in the next decade, Jason's words will shape countless careers.We explore the delicate balance required when creating technical content: providing enough depth for certification success without overwhelming readers, adding engaging storytelling without sacrificing accuracy, and addressing varied audience backgrounds without assuming too much or too little prior knowledge. As Jason beautifully puts it, "When I write, it feels like I'm talking... like I'm explaining it to a specific person." This approach transforms what could be dry technical manuals—"paper cuts to the eyes"—into relatable learning experiences.For anyone working in technology, the episode offers valuable insights on continuous learning in a rapidly evolving field. Jason describes technology as "a train... the second you step on, you're moving with it." The key is simply starting somewhere: "Don't be afraid to get on the train. Just do 'hello world.' Get a Raspberry Pi. Use Alexa to turn off your lights." Whether you're pursuing certifications, teaching others, or creating educational content, this episode provides practical wisdom on making technical knowledge accessible, relevant, and engaging.

I, Stewart Alsop, had a fascinating conversation on this episode of Crazy Wisdom with Mallory McGee, the founder of Chroma, who is doing some really interesting work at the intersection of AI and crypto. We dove deep into how these two powerful technologies might reshape the internet and our interactions with it, moving beyond the hype cycles to what's truly foundational.Check out this GPT we trained on the conversationTimestamps00:00 The Intersection of AI and Crypto01:28 Bitcoin's Origins and Austrian Economics04:35 AI's Centralization Problem and the New Gatekeepers09:58 Agent Interactions and Decentralized Databases for Trustless Transactions11:11 AI as a Prosthetic Mind and the Interpretability Challenge15:12 Deterministic Blockchains vs. Non-Deterministic AI Intents18:44 The Demise of Traditional Apps in an Agent-Driven World35:07 Property Rights, Agent Registries, and Blockchains as BackendsKey InsightsCrypto's Enduring Fundamentals: Mallory emphasized that while crypto prices are often noise, the underlying fundamentals point to a new, long-term cycle for the Internet itself. It's about decentralizing control, a core principle stemming from Bitcoin's original blend of economics and technology.AI's Centralization Dilemma: We discussed the concerning trend of AI development consolidating power within a few major players. This, as Mallory pointed out, ironically mirrors the very centralization crypto aims to dismantle, potentially shifting control from governments to a new set of tech monopolies.Agents are the Future of Interaction: Mallory envisions a future where most digital interactions aren't human-to-LLM, but agent-to-agent. These autonomous agents will require decentralized, trustless platforms like blockchains to transact, hold assets, and communicate confidentially.Bridging Non-Deterministic AI with Deterministic Blockchains: A fascinating challenge Mallory highlighted is translating the non-deterministic "intents" of AI (e.g., an agent's goal to "get me a good return on spare cash") into the deterministic transactions required by blockchains. This translation layer is crucial for agents to operate effectively on-chain.The Decline of Traditional Apps: Mallory made a bold claim that traditional apps and web interfaces are on their way out. As AI agents become capable of generating personalized interfaces on the fly, the need for standardized, pre-built apps will diminish, leading to a world where software is hyper-personalized and often ephemeral.Blockchains as Agent Backbones: We explored the intriguing idea that blockchains might be inherently better suited for AI agents than for direct human use. Their deterministic nature, ability to handle assets, and potential for trustless reputation systems make them ideal backends for an agent-centric internet.Trust and Reputation for Agents: In a world teeming with AI agents, establishing trust is paramount. Mallory suggested that on-chain mechanisms like reward and slashing systems can be used to build verifiable reputation scores for agents, helping us discern trustworthy actors from malicious ones without central oversight.The Battle for an Open AI Future: The age-old battle between open and closed source is playing out again in the AI sphere. While centralized players currently seem to dominate, Mallory sees hope in the open-source AI movement, which could provide a crucial alternative to a future controlled by a few large entities.Contact Information*   Twitter: @McGee_noodle*   Company: Chroma

This week at the Desk of Ladyada, we're getting back into the swing of releasing one or two new products a week after dealing with some tariff-related chaos. Last week we launched the Sparkle Motion Stick and the SEN6x Adapter. Next week, look out for the OPT4048. For the OPT4048, we wanted to easily plot the CIE x & y to a color graph—which used to mean writing a lot of JavaScript (something I haven't done in 15 years). Thankfully, Claude helped generate code, and now it's up and running! Check it out. This week, we also designed breakouts for: ACS37800 30A Monitor, VEML6046, and a Stemma QT adapter for Raspberry Pi bq25798 Solar MPPT Charger. And for this week's The Great Search – 30 Amp Barrier Terminal Blocks

The boys are back! This time to talk about the merits of going suckless. ==== Special Thanks to Our Patrons! ==== https://thelinuxcast.org/patrons/ ===== Follow us

This week's EYE ON NPI is a follow up to one we did a few years ago on the similarly-named BQ25792 (https://blog.adafruit.com/2021/05/06/eye-on-npi-ti-bq25792-i2c-controlled-1-4-cell-5a-buck-boost-battery-charger-eyeonnpi-adafruit-digikey-adafruit-digikey-txinstruments/). The BQ25798 (https://www.digikey.com/short/vnr279pz) builds on the '92 by adding selectable dual inputs and true MPPT solar support. This chip is inexpensive, powerful and can handle almost any battery and power source matching you desire. Let's look at some specifications: High power density, high integration buck-boost charger for 1-4 cell batteries supporting USB PD 3.0 profile – Integrates four switching MOSFETs, BATFET – Integrates input and charging current sensing Highly efficient – 750-kHz or 1.5-MHz switching frequencies – 5-A charging current with 10-mA resolution 96.5% efficient: 16-V battery at 3A from 20V Supports a wide range of input sources Autonomously sampled open circuit voltage (VOC) maximum power point tracking (MPPT) for charging from a photovoltaic panel – 3.6-V to 24-V wide input operating voltage range with 30-V absolute maximum rating – Detects USB BC1.2, HVDCP and non-standard adapters Dual-input power mux controller (optional) Narrow voltage DC (NVDC) power path Backup Mode with Ultra-fast switchover to adjustable voltage Powers USB port from battery (USB OTG) – 2.8-V to 22-V OTG output voltage with 10-mV resolution to support USB-PD PPS – OTG output current regulation up to 3.32 A with 40-mA resolution Flexible autonomous and I2C mode for optimal system performance Integrated 16-bit ADC for voltage, current, and temperature monitoring Like the '92, the BQ25798 (https://www.digikey.com/short/vnr279pz) supports any size battery. We have lots of battery packs in the Adafruit shop, and in particular we use 1S batteries – if there are more batteries, they are wired in series. But there's lot of folks who are building robotics that require higher voltages, so they have 2S, 3S, or 4S batteries. This charger can handle any of 'em, and you can configure the battery pack size using a simple resistor on the PROG port. In this case it also allows the chip to run in 'standalone' mode without the use of I2C to configure. The biggest improvement you get with the BQ25798 (https://www.digikey.com/short/vnr279pz) is true solar MPPT support. The BQ25792 had VINDPM and IINDPM – the ability to track the input voltage to make sure it is not drooping from overdraw. While this lets you get pretty-close-to-MPPT it isn't true power-point-tracking which requires perturbation around the voltage to adjust as light and temperature affect the solar panel's efficiency. The '98 does this 'right' and even has a K Factor adjustment register - you can tweak this to get the best results based on different weather/temperature (https://www.ti.com/video/6287049638001)- or stick to the default value for good results. Another new feature is 'selectable dual-inputs' what this means if you can set up two power inputs - say DC plug and Solar - and then have the chip switch between them. This is particularly useful because you can't just use two OR'ing diodes to select the power source: the solar panel might have a higher initial open-voltage but can't supply as much current as a DC plug. I2C lets you select which one is priority! The BQ25798 (https://www.digikey.com/short/vnr279pz) also has many of the cool features we liked in the BQ25792: On-The-Go mode where you can turn the buck-boost around and have it generate a variable voltage output, say 5V for powering other USB devices. Another thing that works is powering over USB where you can have the BQ negotiate 'high voltage' support from USB 3 ports. Note that this isn't USB Type C power negotiation, for that you'll want to get a separate USB Type C PD negotiation chip like the TPS25750D (https://www.tij.co.jp/jp/lit/ml/slpp103/slpp103.pdf)...we're hoping there's a future version with PD built in! There's also a built in 16-bit ADC that you can use to monitor various voltages and current draw. While you can charge the battery in 'standalone' mode - you really do need I2C to get the best performance and capabilities. Thankfully there's not a huge number of registers, and SDA/SCL can be 3 or 5V logic signals so you should be able to get it working on anything from an ATmega328 to a Raspberry Pi. We like the high integration: you really only need a few passives and an inductor to get a fantastic all-in-one charger for any lithium ion battery pack. If you're intrigued and would like more information, you've come to the right place! DigiKey has the BQ25798 (https://www.digikey.com/short/vnr279pz) in stock right now for immediate shipment. Order today and you can start designing your solar-powered products of the future by tomorrow afternoon.

We're phasing out the Cirrus WM8960 codec (https://www.digikey.com/en/products/detail/cirrus-logic-inc/WM8960CGEFL-V/5036712) used in some Raspberry Pi boards to add two microphones, line-out, and stereo speaker. The codec is great—see our Voice Bonnet—but very obsolete now. Let's hunt for a modern alternative!
