I can imagine building and ordering spare parts for defective and unsupported electronic devices that would prolong their life.
I can also imagine experimenting with building and fiddling with guitar pedal effects from the slew of existing schematics on the Web.
I think the hardest thing for me is going out finding and buying the parts. Some times I might have the time to assemble them but most of the time I wouldn't.
Props to the team, though. I hope this gets traction.
Plug: if anyone has experience making hardware projects (start to finish) and has some free time to lend some advice or would be interested in hearing what i want to make and
maybe team up. email me!: email@example.com
