Subject: [alt-beam] IR object detector and head circuit schematic?
Does any one have an IR object detector schematic? I found one on Ian's page but it is "Under Construction". And does anyone have a solar head schematic? Thanks for the help.

That's true. Pan on the array would be redundant if the bot turns. DUH!
Thanks Richard.
See ya,

excuse me if I sound stupid.
Would it be a solution to assign one process of a bicore to the lightseek=

With that I mean to discharge power to the head once a loop and the remai=
