Daisy Chain!

When I first started doing hardware, I hated doing the firmware. I just really liked making things pretty and putting fun drawings on my PCBs. So, what if I could make the firmware more fun and user-friendly?

Daisy Chain is a beginner-friendly web IDE for coding your own hardware hairclip! Write Python, snap blocks together, or draw pixel art, and it runs on a tiny OLED screen straight from your browser, with nothing to install. It's inspired by the viral "hardware hairclips" and made for girls in tech, or anyone who wants to get into it!
