I've spent some time fixing the provided sequencer code, and I now have a (kind-of) nice step sequencer. Yes, it pops each column, but the code is documented enough now that you should be able to understand how it works.https://github.com/toddkrein/HB28_Sequencer

Hmm... Finished the build, but it ain't working. When I try to upload, I get a lot of ___....___ and then "An error occurred while uploading the sketch.""A fatal error occurred: Failed to connect to ESP32: Invalid head of packet ('w')"And one or more of the LED matrixes are full on.Anyone else have this problem?
The same thing happened to the inductor on my 5V boost board - broke it right in half. The inductor on my SEPIC broke free from the legs and is dangling, but the coil seems to still be connected.When I unpacked my box, both were right next to the power resistors - I guess they have more mass than I expected.Easy to fix with parts from digikey, so no worries, but...
Maybe today, but you keep playing with hackerboxes, and you'll be popping parts on and off like a pro.
