I have a backup cam on my car, I want a little wiper on it, like my windshield. Every time it rains I have to get out of my car and wipe it off with my thumb.

- whamlastxmas 10y agoYou can move it to be inside your car attached to the rear window. Or Rainx.
- ge96 10y agoBuild it, Arduino micro, servo, Bluetooth module. What about the battery though.
- joshmn 10y agoI'm sure you could get decent power from the rear lamps.
- extrapickles 10y agoCan do something even simpler for cars with rear window wipers. Take bike brake line, attach one end to the rear window wiper, and route the other end down to where the camera is and use that motion to run smaller wiper over the camera lens. Probably set you back <$10. For cars without it, use a 555 timer in one-shot configuration+mosfet/relay to drive a small 12v DC motor that is all powered off the reversing lights, so it automatically does 1 wipe every time you shift to reverse. If you didn't want the wiper to spin 360, you can adjust the pulse width of the 555 and use a spring to return. This would also cost about $10.
- ge96 10y agoNice this guy with the real specs, me it's just pseudo knowledge.
- lucaspiller 10y agoOr just get a plastic bottle and craft a small cover to stop the rain getting on it. Mine is angled slightly downwards and is covered (the license plate part and camera are recessed into the body a few cm), so when it rains it's not an issue.
- andrewstuart2 10y agoI wonder if there's any hydrophobic coating you could spray on yourself without turning everything into a hazy or prismy mess.
- CamperBob2 10y agoJust heating the lens would probably help a lot.
- asimuvPR 10y agoRain-x works very well. I had the same issue.
