The iconic Etch-A-Sketch toy deserved an ACES LED makeover. Dubbed the doodLED, 10 instances of our interpretation were developed in the Fall of 2024. JLCPCB was charged with manufacturing and populating the PCBs shown below. The only additional soldering required were the four mini-matrices on the daughterboard. The overhanging ports at the back of the motherboard, from left to right, are as follows,

• 6 pin ISP header for in-system software updates
• a SP3T MODE slide switch (Left-TRAIL, Middle:DOT, Right:ERASE)
• a SP2T Power OFF- ON switch
• a 2.1 mm Barrel Jack: 9V.

NOTE: Please unplug the battery when not in use.
