- inexpensive receipt scanner (good for small photo prints too)
- prototype could use old smartphone for imaging
- hard part: feed mechanism
- foot-pedal for controlling kitchen sink faucet
- Once you get the temperature right, you don't want to turn the faucet off because then you'll have to adjust it again.
- Also, you might have soap on your hands, and you don't want to get that all over the handle(s).

- remote-controlled tree-climbing chainsaw (may be impractical, but still seems possible)
- Laser turntable, but start from scratch using modern tech:
- CD/DVD/BluRay (whatever works best) laser (off the shelf)
- reflections picked up by cellphone camera (off the shelf)
- use images to reconstruct 3d map of groove surface (may need GPU, or slower-than-realtime capture)
- 3d map should make it possible to distinguish dust from groove modulation
- also experiment with dust-removal techniques: brush, air jet
Ideally, should be able to read all audio from fragments of a broken record; software can reassemble into a continuous track, interpolate any short missing bits.
- FinanceFerret -- apparently NuneCo is working on (or has created) an engine for this
