well this a project that absorbed way more time than I planned. mcp23017 and encoders to control raspberry pi running #Zynthian. turns out the only solid core wire I had on hand was just red or 0.1mm magnet wire. but it&#39;s 99% done. just need the ground bus, but thats tomorrow&#39;s problem.

I know once upon a time I had an sdmmc breakout board, but after digging through all of the bins/bags/boxes/buckets and other b-containers it is simply not present. So guess I&#39;m ordering a couple. Blerg. I recently got a hothouse daisy seed based guitar pedal, and I want to turn it into a looper, so I&#39;m intending on adding an sdcard breakout as well as midi-in so I can hopefully pass a midi clock to it and quantize the loops.(We&#39;ll see if I can actually code this idea.......

My phone has a &quot;magnifier&quot; app to use the camera as a magnifying glass. I wonder what I use it most for.....

For anyone that may be on Fedor43 and running into build issues, apparently there&#39;s an issue with arm-none-eabi-gcc-cs that fails to properly cross-compile. You have to force it to update to the &quot;rawhide&quot; build temporarily which has the fix, until the fix is pushed to main. Details found here of someone having the same issue building for the Pi Pico. https://forums.raspberrypi.com/viewtopic.php?t=393796

Finally going to call my DIY #Zynthian &quot;Done&quot;. Just did a little jam with it. Pretty sweet to have drums, synth, and an entire guitar effects chain including amp modeler and cabinet IR all in a single module, and able to record with it. Still a lot to learn and a long way to go, but now it makes noise. And I can run the whole thing on a battery, which is pretty sweet.

Does anyone know of a good audio focused tutorial/lesson/course on opamps? I&#39;m rusty since school, and honestly was never that great at analog. I&#39;m looking on setting up a good instrument level input, a balanced mic input, and a few line level inputs into a 32bit DAC. The DAC has an example buffer opamp for input matching, but I&#39;m struggling for info on preamps(more specifically the instrument level input)
