Step 71: Handle/Electronics: Looking Back

The previous switch designs were electronically similar, but had some shortcomings. For that reason, I'm just going to show you some pictures and discuss them a little bit so you can benefit from my experience.

The first switch I made was entirely recycled. I had a switch and LED board from an old printer, two motherboard memory backup batteries (scavenged from bad motherboards) in series, and the guts of a broken USB hub. This design was bad for two reasons. One, it was mounted on the same arm as one of the cameras, so every time I took a picture I disturbed the camera position a bit. Second, those motherboard batteries are not cheap or easy to find if they need to be replaced. Finally, this circuit was a bummer because the LED rarely lit up. Still don't know why.
