Just a quick post to say that you can now buy DrumKid online! It's been quite a journey - I decided to make DrumKid into my first ever commercial product when I saw that the 2019 Hackaday Prize had a theme of "design for manufacture". 18 months on, and after teaching myself PCB design and going through many iterations, I've finally made my first batch of DrumKids and made them available to buy on my website.
I've also made a tutorial video to accompany the launch, which you can see below. I just want to say thank you to the Hackaday community for motivating me to start this project, and for encouraging me to finish it. This website was the inspiration for this project, and is also the reason why I made the design deliberately hackable!
