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 second eye will be a color sensor, based on the TCS 230.

That is some very nice work.

I will be curious to find out how sensitive it is, compared to OddBot’s eye.

Thanks, birdmun. The range

Thanks, birdmun. The range of mine is a little bit bigger as the IR LED’s are centered and not positioned in a row, as far as I could observe, testing both.

I like what you’ve done

Looks good Markus. Dammit Birdmun your always ahead of me with my thoughts. I am also curious about how the sensing properties compare to the original.

Another interpretation of a compound eye

I just stumbled on this after watching a video about michigan techs water glider.

Someone else’s idea of formfactor for a compound eye
