Tech jewelry and circuit board modules by me (Alex Glow)!

In 2018, I started designing small, modular circuit boards for electronic-augmented jewelry: Charmware. The goal was to make simple and open-source designs that would be easy for a newbie PCB creator to learn from.

In 2025, after creating many functional boards, I realized that I currently use the charms to make ad-hoc workshop tools. The new boards are still tiny and modular, but I’m making them more beautiful, with intricate hand-drawn art elements.
