How to Make Your Own Water Light Graffiti at Home with LEDs and PCBs
Last week, we wrote about Antonin Fourneau's Water Light Graffiti exhibit in that used LEDs to create a huge Buddha Board that would light up anywhere water touched it.
Chris Woodall of Happy Robot Labs created a tutorial so that you can make your own Water Light Graffiti at home with some LED boards, 3mm water sensitive LEDs, and wire jumpers.
He did the schematics and printed circuit board in KiCAD, which he posted on his blog.
He also put all of the code for the project on Github, so if you want to try it out yourself, make sure to visit his blog for more information.
