2 years ago I was tinkering with the first prototype of the “Plus” board. The goal was to upgrade the physical experience of using a @SeedSigner — larger screen for easier reading and better QR xfer, drop the stabby nub for a DPAD, swap microUSB for USBC and get the cord out of the way, and make interfacing with the microSD slot easier. And then bringing the pill shape back was a bonus win. Myself, @KeithMukai and a Noderunner called “MadBo” (who was also the co-creator of the BTClock) agonized over the specs, sizing and layout for the board. We must have gotten some of the details right because thousands of them have been deployed to bitcoiners around the world, and I think I can safely say that the majority of them have not been produced or sold by me. The design has also been forked to accommodate smart cards, batteries, and in one case, both. Although open sourcing both the board design as well as the reference enclosure wasn’t the most lucrative path, it was the best one because it’s allowed the magic of the SeedSigner project to make it into the hands of many more people than it might have otherwise, while also materially upgrading their experience of using a signer. We have much more in store wrt open software AND hardware development with the planned support for microcontroller architectures, but every once in a while it’s fun to glance in the rear view mirror and reflect a little on how far we’ve come. 🧡
