And here are the finished products. All tested and verified to work properly.
3/5 were perfect on the first try and the other 2 were fine after a little rework.
Discussion
I'm interested in the project, but I didn't see anything about creating backups. In the event that I break the device, say it was crushed in my pocket, would I be totally screwed?
Can I purchase 2 and have them sync together? If not, that's a neat idea.
Cool project, though! I'll keep an eye on this one.
