Oh yeah, I saw y’all on Nostr the other day. Looks pretty cool. They both put together their own gaming PC’s so I think this could be a fun family project.
If they are building gaming PCs this would be a perfect ‘winter’ project! They can build the device and learn the ins-and-outs of UXTO management and PSBTs. Then get some stainless steel washers and a some letter punches and make offline backups!
