What is this mysterious steampunk creation roaming through the jungle? It seems to be drawing perfect sine waves with little to no effort – how can such a machine be created? Watch as Tom Rocks Maths intern Joe Deakin attempts to make a machine to draw sine waves for him, using only things that he can find around the house! As you’ll see, it was quite a challenge to get it all working but Joe seems to be pretty pleased with the result.
