My first (proper) hack

Here’s a video I made of my first proper hack. It’s one of the simplest hacks you can make to any toy, simply changing the clock speed to make it run faster or slower. In this example I have soldered two cables to the circuit board, and the connection is made through the resistance of my body. I am able to vary it by pressing harder and softer on the ends of the wires.

Below is my short explanation on youtube:

Here we have a magic eight ball-style decision making toy that cycles through various options when shook. I have hacked it by making a connection between two points on the circuit board. By using my own body as the clock resistor, I can alter the speed (and therefore pitch) by changing the pressure put by my fingers on the two bare wires. As you can see, if the resistance is too low it will just completely stop. I have also added an off switch, so that I can shut it up.
