Here is a project i built with the help of Solarbotics.com & Solarbotics.net. It's a Pummer and it's made to resemble a Rocketship at a playground I used to visit. I added the Pumming circuit and LED's to make the ship more alive and how I imagined it to be if it were to ever become a real flying Machine.

I did a bit of reverse engineering on the Pummer Kit I purchased from Solarbotics.com, and I added a few mods from the circuit on Solarbotics.net (under complete robots -> Pummers). The kit that i purchased from Solarbotics is no longer available but there are now new and improved PumLanterns.
