I'm sad that I only found a couple people interested in this idea, but at least now I know not to put any more effort into it. I want to see more open source hardware in the world. Ah well, c'est la vie. #FailFast and all that.
I'm sure I will eventually find some project that can be funded with nostr:npub16jdfqgazrkapk0yrqm9rdxlnys7ck39c7zmdzxtxqlmmpxg04r0sd733sv's CoinFundIt. It looks like that platform has a lot of potential.
