Micro LASER Show with a CD Lens Mechanism using Arduino

Micro LASER Show with a CD Lens Mechanism using Arduino

Hello! This is the cheapest and easiest way to make a two-dimensional laser show projector. It uses just one pivoting mirror, powered by the focusing mechanism from a CD or other optical drive. They said it couldn’t be done, but Ljudmila‘s skunkworks GRL research facility delivers anyway! 😉 This design was first discovered in 2006

Arduino Digital Selection Pad

Using Copper Tape To Create A Digital Selection Pad using Arduino

This is partially me sharing this technique, and partially me learning how to use Instructables. If there are issues with my documentation of the technique or my use of Instructables, please let me know in the comments – thanks! I needed a long row of switches in a pinch, and didn’t have nearly enough switches

Arduino buttons

Accessing 5 buttons through 1 Arduino pin

I made the original Instructible that this is based on over a year ago (You can see it here to see some of the theory around how this works:http://www.instructables.com/id/How-to-access-5-buttons-through-1-Arduino-input ). To make a long story short, I moved to a different country a few weeks after that and have not played with any electronics since.
