Light bender is a board game i made using a Red, Green & Blue lasers. The idea is to use mirror's to route the laser beam to a target through the acrylic sheet. Not just bouncing lasers around in the air but the lasers light travel through the acrylic to reach the target. This makes it harder to play since you have to place the "blanking" pieces in the holes to convey the light and complete the path.

See it in action over on Youtube: https://youtu.be/ifkgCdoMrVc

Let me know if you would like to see a "making of". i tend to focus on whats possible with tools like 3D Printers and laser cutters and not so much the how to do it, there's lots of content around focused on that sort of thing.

There are 9 red-green-blue LED's placed around the play field, each with an accompanying light sensor.

The game starts by triggering the proximity sensor at the top of the board and a random LED will light up a random colour. The same coloured laser also turns on and the clock is started at 20 seconds. When you complete the beam path to it's target, the next colour & laser is randomly selected. The remaining time on the clock adds to your score.

Past level 15 the time to solve each level is reduced. Eventually to 6 seconds. Failing to solve the puzzle in the time limit will end the game.

Parts used... 1x Green laser pointer 1x Red laser pointer 1x Blue laser pointer 9x WS2812 RGB LED 9x Light dependent resistor 1x proximity sensor 1x OLED display 1x Speaker 1x Arduino Mega2560 Mini 3x BD135 transistor

The top clear acrylic and lower ply pieces where cut using a laser cutter (K40). I used a vinyl cutter to cut the black and white decals placed under the clear acrylic. And finally i 3d printed the laser mounts and covers to complete the game.

NOTE: you probably shouldn't build this...laser safety and all that!
