Podcasts about 12ax7

On this quick bonus episode, Elecia and Christopher chat about their various recent projects, some of which have just been released into the wild. Christopher's band 12AX7 just launched their album Kickstarter, which was selected as one of Kickstarter's "Projects We Love”. Check it out here if you are interested in finding out more or backing it. It'll run through July 16th at 10am Pacific Time. Elecia's Embedded Online Conference talk on map files will be posted publicly on June 22nd, so be on the lookout for that. In the meantime, the slides and examples are available here at embedded.fm/blog/MapFiles (and on Github) If you'd like other Embedded merchandise such as a mug (many different options), Memory Map Land mousepad (or different poster), we have a Zazzle store. Her lightning talk about origami, Snails, Paper, and Programming: A Computational Approach to Mollusc Morphology in Origami, is already on Youtube and you can watch it now! Elecia's origami github can be found here. Finally if you are interested in having your cat or cats appear in 12AX7's upcoming music video, send Dropbox/Google Drive/iCloud/whatever links to your clips, along with how you'd like to be credited, to show@embedded.fm. Use the subject line “Cats for 12AX7”.

A pure celebration of geekdom and nerd squads. As I said to my daughter just before recording this: "I'm like a super geekazoid, huh?" Her answer: "Yeah you are." Aha! Someone agrees with me! This episode stays in the technical domain. There's a lot to talk about in the world of computers and the components that enable them. We will be going from a discussion of Raspberry Pi to the Apple M1 creating a mighty hunger for some Apple Pie.I received a parcel from across the pond today. It contained a Raspberry Pi Pico, the new $4 programmable microprocessor, arriving from the England. The Pi Pico intrigues me because I have already thought of some cool projects to use them for. One of the projects is a sweet Valentine's oriented couple's project: to merge my sweetie Sue's hobby (arts and crafts) with my geeky creations to create something interesting and fun. Now I just have to implement at least part of it by Valentine's day because I think this is a clever, unique, interesting way to bring our leisure hobbies together. How much more (super geek) romantic could something be? I am not joking about this either.I had already been in the middle of several Raspberry Pi projects using Pi Zero W, several Pi 3bs, and a Pi 4/4GB RAM. The image for this episode shows some of the Pi boards, my soldering workstation, and peripheral components such as a hi quality camera, sound cards and synthesizers, a breadboard and other cool nerd toys. If you look closely, there's a yellow CD case from Symantec C++, a product I worked on while working at Symantec in the early 1990s. It's there as a reminder and behind it are some Jibo robots. I "stage" my work areas to always include something inspirational whether a book, product, picture, guitar, piece of some product from my 40 years as a maker, or pictures of puppies.Many products are mentioned. None paid or asked for placement. This remains an non-monetized, unbiased, rant-oriented podcast series. But at the end I hint that one of the companies should consider sponsoring me in some way based on the plans I have to do business with them.Music is just some pre-Super Bowl snippets from a 45 minute, high gain, loud, experimental jam. It was like driving a Mustang Cobra with 600 Horsepower on the verge of losing its grip on the pavement. This is why we love tubes. The responsiveness and added harmonic content is delicious and oh so satisfying. Apologies to Ms Sue. I played super duper loud pushing all 4 tubes in the recording chain to their limits and letting the Tele bridge pickup work it's magic. Played on Liz The Firecracker (2020 Squier by Fender Affinity Tele with special upgrades) through Blackstar Studio 10 KT88 with new Genalex Gold Lion tubes for both the 12AX7 preamp and KT88 power amp. Another Gold Lion in the SM57's signal chain pointed two inches off center of the Celestion, and an Electro Harmonix 12AX7 LPS in the Rode NT5 room mics signal chain. All tubes hand selected and modern Russian-made reissues of the classic British tubes.Blah, blah, blah. My intros are longer than the episodes!

Some strong statements about software development and choosing it as a lifestyle. It's all good fun until someone squelches your creativity. Or stuffs you in box with too many walls and obstructions. You've probably done this to someone yourself. We all do. But we shouldn't. There's a real cost to the lost innovation. The grind yields 1X of the capacity of a team. A disruptive creation could be a game changer. Not just could be, it is likely to be. People innovate and solve for their biggest absorbed pain, or for the customers, or their coworkers. Give me a 1X return with 0% breakthrough bet and I'll pass. Give me a 90% grind output plus 10% chaos theory running amok, any day. You won't beat 1X return every roll of the dice, but imagine the outcome of it coming up once every 3.5 rolls on average or even every 6. In a year you can blow the lid off the norm. IMO you have to do this. Because the grind never wins. Anyone can do it. And the human cost is toxic and counter-productive. Vote a little chaos in 2021 to experience some growth.There's a strange snippet of a protest song called "Depleted Optimism". It's about how we take people, get them excited, and then stuff them unceremoniously in a box that all but assures low quality results. It's a really rampant problem. I have some ideas on how to solve it.Later we visit a new song and an old song both written by Dennis DeYoung, formerly of Styx. One is Dennis' hard hitting "With All Due Respect", also a protest song, that rages at the media (and more--the top of the food chain). This is probably Dennis' greatest rock song ever. Performed and video made through the pandemic with home made video. Long live rock and roll. I utilize "Fair Use" doctrine to sample a very short segment just to make you hip to the song and go consume it fully and legally on youtube. Legality ends there when I play one of my favorite songs to play/sing on acoustic guitar, and one of my all around favorite songs: Suite Madame Blue. Not Dennis. Me. But a different take and only one minute long. Takes you from a room into a cavern as it builds from the farce about the song being about a woman and lets loose on the true subject: America.The overall audio quality is good. I have been building new signal chains, mastering techniques, getting better equipment and using Apple Logic Pro to produce. Rode NT5 AND Shure SM57 used on all takes on guitar and vocals. Both ran through high quality Russian-made 12AX7 preamp tubes (a Genalex Gold Lion and Electro Harmonix 12AX7s). Acoustic Seagull Maritime SWS Mahogany HG. Three tracks vocals achieving space effect and double track reinforcement. Also used a little audio crack (addictive little tricks) to make every sound exciting and happening.The image in this episode is in lieu of a magazine cover. I need to get good photos of the magazine covers I've had with tech articles. This is the last version of a product I co-created originally with an early toolkit of asynchronous networking, telecom, serial, networking stacks and other essential tools to communicate in real time with clients and servers alike while at Turbo Power Software. The connection will unravel in the episode (or will it?).The songs "Society for the Free Mind" (not in the episode) and the full "Depleted Optimism" are on SoundClould in Pandemic Richie and the Quarantined Profile. https://soundcloud.com/rich-sadowsky-468824781/society-for-the-free-mindLabeled (take 2) because I pulled an earlier version that I decided was not the right message. After producing this episode I had technical difficulties uploading the Apple Lossless Encoded version. Typically that works fine. Too big for a wav, so I tried high def AAC. Bingo! Success. More proof of the importance of experimentation.

Okay, here's the next episode of your Amps and Axes Podcast. It starts with a couple of topics prompted by listener questions. First, Jeff addresses a question about  his favorite Super Reverb amps. Then, there's a little talk about preamp tubes, complete with mention of a couple of links (provided here) that give a very comprehensive description of all the currently produced 12AX7 and 6L6 style tubes. Then the guys bring in their guest of the day, Craig Poole. Craig had been a professional tech for many years and has just recently come off the road and moved on to his next endeavor, so let's find out the who and the what of his past and the where and why of his future. Enjoy and Thanks for Listening. Onward!

You can control the amount with the send fader. However, when I want to compress two tracks, say two vocal tracks while recording, I don't think it works the same way. I think you need to send each track through its own compressor. Otherwise transients from one would affect compression on the other. What's your opinion?" Celebrity Interview: Al explains that a while back he found another podcast about home recording that he really enjoyed called Home Studio And Audio Review. Unfortunately, it's no longer being produced, but all of the shows are still available for download. Mike and Al caught up with one of the hosts of the show, Mr. Matt Long. In the interview Matt passes the torch to PSN for a new style of Trivia Question he used to feature on his podcast.
