Today I made a short live demo of the Outmoded Sequencer. I just added briefly some audio effects at the end of the video, so you can hear the real sound of the device. Adding effects is a really great way to turn the beep sounds in interesting music.
You can also see the connection problems sometimes happen. A short push on the steel ball solves this problem usually.
Let me know what in think in the comments. Next I will finish the second part of the guide, where I explain how everything was built.

I walk you through using the RP2040's PIO to measure a PC fan's RPM with a small software filter to ignore short spikes and timeouts. I explain the PIO routine and a simple RpmInput wrapper in MicroPython—read on if you'd like the code and practical setup tips.

I just received the PCBite Kit 2.0 from Sensepeek and explored its mirror board, magnetic pogo-style probes, and PCB holder. I found the gold needle tips and crown forks helpful for accessing tiny pads without test points. If you work on soldering or circuit analysis, read on for my hands-on impressions.
