Ever look at a pile of 10mm LEDs and think “mmm, they look just like gumdrops!” These LED gummy candies are so realistic they’ll have your friends fooled at first, then delighted that they are actually edible (and delicious). This tutorial covers the basics of food-safe silicone mold making and provides a recipe for gummy candies you can make at home.

Here it is, just in time for the holidays! A gingerbread circuit based on the same class AB amplifier I made last year for a Hack A Week project. An explanation of the circuit, the schematic and a parts list can be found on that post. This project is about edible gingerbread circuit boards and how to create them.

I used Gingerbread mix for the perf board and capacitors, string cheese for the resistors, candied sugar for the diodes and transistors and licorice whips for the wires.
