Well, I am a developer, and I already have a pi zero zero...
The camera and screen are about $40 in total (after shipping).
If I get at least .0014 BTC to bc1pckaq2raj47nhmyzwrsjvfztnf9gmsfq7f0s5z3337jd8yy5ey5rqk2zqvz I vow to order the parts and take a crack at this. I'll post my progress on nostr as I go and all code and instructions will be MIT licensed (same as SeedSigner). Bill gets to name the project. Those are my terms.
Any extra coinage would serve as more motivation for me to make it a priority, put extra polish on it when it's functional, etc.
