Getting to Know Mr. Two Eyes

I was looking for a way to make a vibration robot from salvaged electrical components. I wanted the bot to simply vibrate across a surface and  wanted his electrical hook up to look tidy.  I made his body from a capacitor and soldered 4 resistors on for his legs. Note: It’s not necessary for all of his legs to touch the ground, in fact, he will tend to move more erratically if just 3 legs are in contact. 


I hot glued a small motor to the top of the capacitor, gluing a small object to the shaft to help wobble the bot. I then soldered the positive and negative leads to a coin cell battery holder.

I was able to hot glue two google eyes onto the motors leads (use just a little hot glue as too much will melt the back of the plastic eye). I think he’s quite attractive. Don’t you?

What Has 2 Eyes and 4 Legs?

There are many ways to recycle the fans from unwanted electronics. Here’s one way our class gave new life to a supply of dusty fans. Simply break off 3 blades: the blades must be consecutive to create the wobble.  After removing the stickers from the fans (this would help the hot glue hold better), we attached a 9volt battery and a battery cap. We attached our wires to the correct leads from the fan and wrapped them in heat shrink.  A small alligator clip was attached to the positive lead to create a handy on/off connector.

Hot Rods from E-Waste

CRES students in computer lab’s “Hot Rods from E-Waste” class made great use of electronic waste. These photos feature a sampling of their work. Their vehicles will be displayed on October 10th at the Rotary Club’s DogFest3. This event features “Vettes & Pets” and is co-sponsored by the Rancho Murieta Corvette Club. The event takes place in Rancho Murieta at Stonehouse Dog Park, 11am – 3pm.

Getting kids prepared for working with electronics by providing them with electronic waste is a wonderful way to encourage creativity and spark invention. Kids become incredibly inspired when given the tools necessary to take things apart to see what’s inside that makes them “tick”.
