My build for round 6 of Rogue Olympics 2026 with the theme "Spark".
While sparks aren't what you want to see on your circuit boards, they're what make them work! I included capacitors, a resistor, a CPU, a driver-looking thing, and LEDs.
The LEDs are from LEGO light bricks that I took apart and the ethernet-looking cable is actually a LEGO Mindstorms NXT cable. The smaller wire on the right is a LEGO train axle in a flex tube.
In memory of all the components I fried this last semester.
