Homemade compound eye

The compound eye from DAGU, designed by Oddbot, is cool and cheap. But I needed a round board to imitate the human eye, so I made one by myself. The IR LED's and photo transistors are the same as in the original design. As I had no PN 100 transistor, I used a BD 139 (the 4 IR LED's draw approx. 100 mA @ 5 V).

The robot is based on compound-eye sensor: an infrared sensor that, with a minimum of programming, knows if the object moving ahead, is going up, down, right or left.

When I saw the "Mr. General" robot by oddbot (link), I loved it. I thought it is "expressive", a skill difficult to find in a robot built at home. So I built my … Read more

SolderJunkie Construction

2010.03.14

Hi, I have started work on project named SolderJunkie. I want it to be a motorized solder fume extractor. He is going to use a Picaxe 28x1 as his brain, DAGU IR compound eye, few servos and CPU cooler for parts. I only started construction of mechanics, so far. Here is his first pic:

This is the fusion of my old Qwerkbot project and a 4WD base, with omniwheels replacing the originals. I've also attached one of Oddbot's compound IR sensors for … Read more

Ever feel like your being watched?

I was checking some samples to go to Germany and had a strange feeling that I was being watched.

Maybe this job is getting to me. (all the eyes....)
