This Upcycled Robot Sculpture would be great on a desk or as a disguised kid's nightlight!
I think the feet are vintage guitar wah-wah pedal unit parts. I used old wrenches for the arms. The body was originally a metal box that had a light in it. The head comes from a computer case ventilation fan unit. I installed two translucent glass cream pots to create the eyes. Next, I installed more lighting, but to prevent overheating, I used only LEDs. This was a simple electrical installation. Some additional details include a bit of cheese grater for the mouth, a bicycle gear on the chest, and a cool taillight for the main yellow lamp. This sculpture makes a beautiful, soft glow that would even work as an awesome, disguised kid's nightlight.
Here's another fun idea for the kids - an Upcycled Kitchen.
