Tod Kurt (todbot)<p>I've made *many* little SynthDIY boards over the years, targeting: low-cost, for newbies, Pico &amp; CircuitPython. Here are some. <br>I've never been quite satisfied w/ the results. <br>Maybe the solution is more knobs &amp; more choc keyswitches?<br>Good idea?<br><a href="https://mastodon.social/tags/SynthDIY" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SynthDIY</span></a> <a href="https://mastodon.social/tags/RaspberryPiPico" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RaspberryPiPico</span></a> <a href="https://mastodon.social/tags/CircuitPython" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>CircuitPython</span></a></p>
Tod Kurt (todbot)<p>For the last month or so I've been working on seeing how far I can push CircuitPython into emulating a TB-303 bass synth. With the new audiofilters library, you can "stack" filters to make two two-pole filters seem like a 4-pole filter, getting close to that squelchy sound we need. My efforts so far: <br><a href="https://www.youtube.com/watch?v=1AflpXbEIno" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="">youtube.com/watch?v=1AflpXbEIno</span><span class="invisible"></span></a><br><a href="https://mastodon.social/tags/circuitpython" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>circuitpython</span></a> <a href="https://mastodon.social/tags/tb303" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tb303</span></a> <a href="https://mastodon.social/tags/synthdiy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>synthdiy</span></a> <a href="https://mastodon.social/tags/raspberrypipico" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>raspberrypipico</span></a></p>

j4n3z<p>První release PicoBike kompletní 🥳<br>Ve verzi 0.1 je funkční rychloměr a vzdálenost trip. Zároveň hardwarově jsem ještě daleko od toho, čeho jsem chtěl dosáhnout. Ale jako pracovní verzi to považuji za dost dobré na to, abych projekt chtěl pustit do světa 😊<br>Přijímám kritiku, rád zodpovím dotazy a ještě raději se poučím jak co se týká psaní kódu, tak co se týká správy repozitáře.

Brad Linder<p>This DIY handheld combines two Raspberry Pi Pico boards (one for CPU and one for GPU) with a keyboard and 5 inch display.

Pare<p>I got a Raspberry Pi Pico 2 some time ago, basically because it looked cool and one could perhaps do some RISC stuff on it.</p><p>Looking at the specs, it’s similar to the high-end home computersof the late Eighties - think Atari ST or Commodore Amiga (though no special chips). Similar RAM, storage, and 20 times the clock speed.</p><p>Then the projects I can find on the web are LED controllers and plant watering systems.</p><p>1/2</p><p><a href="https://kamu.social/tags/raspberryPiPico" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>raspberryPiPico</span></a> <a href="https://kamu.social/tags/amiga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>amiga</span></a> <a href="https://kamu.social/tags/atarist" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>atarist</span></a> <a href="https://kamu.social/tags/coding" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>coding</span></a></p>

Thinking of releasing a new MIDI controller, but “pad trigger” style rather than “music keyboard”. What do people think? Yes?
Could make a good macropad too. It has reverse-mounted neopixels that shine through the PCB to light up next to the pads. Looks pretty cool I think! The sounds you hear are an off-screen laptop running Ableton, this is just a USB device, it doesn't make sound. Demo code in CircuitPython

Thinking about how to store some persistent information in flash, stashed at address 0x80000 or something, alongside the main binary, on a Raspberry Pi Pico.

I'm kind of torn between trying to keep things compact, I'm storing fairly short strings and such, so how much space to I need to reserve, really?

On the flip side, I'm using an 8MB flash chip, so there's plenty of room for each property to have its own 256 byte page just for convenience.
