Instructables Touch Sensitive Light Painter with Multiple Colors

diybrian

This touch sensitive light painter can paint photographs during night time when you use long shutter speeds. It has 5 different colors, each controlled by its own MOSFET based momentary touch switch. It is powered by a 9V battery and mounted inside a pen case I had laying around. You can come up with your own enclosure solution.

To use this light painter, simply touch one of the LED's touch switch while touching the common contact and start painting!
