Rather excitingly, DrumKid has made it to the finals of the Hackaday Prize 2019! I got through to the semi-finals last year with my digital modular synthesizer, PolyMod, but really struggled to meet the criteria for the final - I was still using stripboard for all my projects at the time, and I didn't even know what a schematic was (I instead submitted a messy pencil sketch of a sort of flowchart).

In the past year, I've put a lot of effort into moving on from stripboard, wood, drills, and saws. I've acquired a 3D printer, learned to use KiCAD, designed and ordered my first PCBs, and generally moved a lot further towards my goal of designing something that looks professional (or at least less amateur). I've also belatedly learned what a schematic is, and produced some!

I'm really happy with DrumKid's progress so far, and luckily I've already fulfilled a lot of the criteria for the final round, but I'd still like to put in a big push to improve the project by October 1st, the deadline for the finals. I can't go into full production mode by then, but I can lay a lot of the groundwork. Here's my September to-do list:
