Sometimes the simplest projects can be the most impressive. Most of the time our simple projects are not as neat and elegant as our more time consuming ones. Sometimes they don’t even leave the breadboard! When [Sasa Karanovic] first envisioned his key-chain idea, he knew it would be simple. But he made up for the lack of sophistication with style.

After assembly, the circuit assesses the skill level of the soldering aspirant based on a built-in scoring system.
The challenge is meant to be played on a time limit. There are no two same-sized components of different value, so contestants may focus on …read more
