We think kids should be encouraged to make things. Electronics may sound complicated and even a bit scary but with this project we want to prove to children and parents that it doesn't have to be!
With a little bit of help from a grownup even young kids (age 6+) can build their own nerve spiral game.
Components
1×
Active buzzer
1×
Crocodile clip lead
You only need half a lead
2×
Dupont wire female-female
1×
20 cm unisolated conductive, bendable wire (0.8mm)
We're going to make a nerve spiral. It is a game where you have to guide a metal loop along a spiral (or other shape) of metal wire. When you touch the spiral with the loop you will hear a noise and have to start over.

Step 1
Cut one of the dupont wire's in half. Strip the wire for 1cm and fold the metal wires at the end in half.
Place the metal wires on the side of the battery marked with a +.
Attach the wires to the battery with a piece of tape and press it firmly.

Step 2
Cut the crocodile clip lead in half. Strip the wire for 1cm and fold the metal wires at the end in half.
Stick the metal wires with a piece of tape on the other side of the battery. Make sure that the metal wires do not touch the edges of the battery. If you do, the battery short circuits and gets hot.
Tip: add 2 transistors to make the equivalent of an SCR, so the buzzer stays on upon triggering until circuit is "reset".
