Subject: [alt-beam] Chloroplast SE
Do you have a link for the schematics/parts list for the chloroplast SE.
i got the 2 PCBs in the mail. I forgot you were sending them and didn't
realize what they were till I looked at them. NICE!!!
It looks like 4 parts. I understand V (+) & (-) and M (+) & (-). I
Assume C (+) & (-) are for the capacitor as well. There are 2 closely
spaced pins underneath the R1 position. What are those. I heard it has
a steady 5 volt supply for powering chips. is that what those pins are
for? The values of the 4 (???) components would be helpful.
Just curious, but can it handle a 9 volt 60 mA power supply? I have the
6x6 inch panel from All Electronics, and I'd like to make a robot using
it. I need an SE to run a Bicore or a Unicore and two MAXON motors (the
ones that MECI sold).
I look forward to trying out this type of SE.

well actually i dont really understand it by the meaning of gravitational
pull.....well maybe mark has this idea but what about other beamers like
darrel johnson his solar walker didnt need any stops......and if someone out
there knows......maybe wilf could whip out a circuit about a leg that stops
before it the walker falls on to its butt....so any other comments from
other walker fans?thanks a lot dave for answering me.....
