I built this in electronics and robotics, and this is a circuit that shocks you when you touch the metal strip (top right) to the metal wire loop (bottom, thick wire). This completes the circuit, letting the electricity flow. There is a knob that you can turn to regulate how big the shock is going to be. There is also a switch, and if you flip it, then instead of shocking you when the circuit is completed, a light turns on.
there is also a hook at the end of the strip, so you can play a game where you need to take it through the hoop without touching it. The reason why I am really proud of this project is because I have always been interested in circuits and stuff using them. This is my first “big” project that isn’t just a simple one way circuit, which makes me really happy that I am advancing in something that i love doing.
