where cn i find 1, iv build a few BEAM robots so far but i like this one

[Upa666]

aww man.. i want one :(

Sweet, I found it! You've inspired me to build one of these. Very cool seeing it tonight. We'll have to get together so you can get me pointed in the right direction owards getting started.

Very nice! I admire the smooth tracking without oscillations. How large is the storage cap?

[pscmpf]

Great question - I am not using a storage capacitor. My first version of the circuit used a photopopper - I found it to have a jerky movement. I removed the photopopper circuit and found the solar panel produced enough current to power the motor with smooth results.

There is a downside to this. If there is insufficient power (light) available, it doesn't work. Do you have any suggestions on a better design?

[beamaed]

Maybe the "barebones" circuit? I used a bicore, and it shakes back and forth when facing direct light from a lamp. It works well outside though. Again, nice job.

beamaed should give you some tips on how to make a better design if you had not seen his yet.

That's so cool! How, mechanically, does it turn?

[pscmpf]

There is a gear head motor with it's shaft connected to the base. When the motor turns, the whole head turns. Does that kinda explain it? :)

Perfectly!  Very neat!
