Pocket LASER engraver. Uses VD drive parts for motion. I feel its time to share my latest project - a low cost laser engraver,. The workspace is a bit small but none the less it works and comes so cheap that most will be able to replicate the result. I did take a few shortcuts, as I feel I dont have the knowledge to do all the electronics I opted for readymade but low cost in favor of trying to make my own (and most likely fail). All parts used are however easy to find.
This instructable will show you how to construct a basic interactive laser-sensitive target, great for those just getting started with Arduino. This could easily be used as a platform for a laser tag system, or just something fun to play with! It might also drive your cat insane. Here's what you'll need to build it: an Arduino board (I used UNO) 4 red LEDs (you could always change the colors or use multicolored LEDs) 3 green LEDs 1 blue LED 1 photosensitive resistor 1 5k potentiometer to adjust sensitivity wires (obviously) A solderless breadboard or MakerShieldan hour or two, and some patience! the Arduino IDE installed on your computer.
