Subject: [alt-beam] solar head questions..
These are some questions/ problems a few of us have been having with the
solar head project. I thought i'd ask.
1. for use in solar power, Where would you hook up the motor driver?
2. The circuit works but he active circuit indincator light NEVER stops,
even when it moves. What's up?
3.The circuit seems to work right when i move my finger over or touch a
certian component. Why does it do this and how do we fix it?
These are some problems myself and someothers have been having and any
help or input would be much appricated. The responses would help all of
us, I think. If anyone has a question to add to this lidt plese do so be
cause it will help us all understand better and mabye avoid future
problems.
thanks,
The Solar Head Project people

1.what motor driver?
2.Without the solar circuit ie battery power the light stays on. Darrell
added the FLED to "attract attention" to the solar PShead when it is ready
for action.
3.That certain component wouldn't be pin 6 and 8 of the HC240? Those should
be connected to 0V (instead of floating as shown on Darrell's layout
drawing. Also make sure you add a small (eg 10uf /10V) electrolytic
capacitor from pin 20 to pin 10. The actual cap value does not matter much
but it should have relatively direct connections with short leads. This
stops high frequency oscillations which upset normal circuit operation.
Keep em coming guys and do read the manual.

7477 Tue, 9 Nov 1999 17:15:00 -0800 (PST) [alt-beam] photopopper woes beam@sgiblab.sgi.com Evan Dudzik
okay, I made a photopopper from my own tutorial... it
seems to work with the right motor, but the left motor
has that buzzing noise to it. I went to chiu's
tutorial, and looked at the troubleshooting part, and
it led me to believe that the 3906 was the problem...
I will redo the solder joints tomorrow(too much
soldering tonight aaagggh!) but in the meantime, does
anyone want to please check the connections on my
tutorial to make sure it is correct? thanks.

ok. the circuit will directly power a led, for some reason not a pager
motor. who woulda knew?(I'm not the only one with this problem)
My analog meter tells me its like 20mA output, my pm needs like 40mA
and would prefer 80mA or so. so i attached a 245 driver and it works
real nice. i was wondering how to connect it to the circuit so it was
only on when the motors kick on. I tried like 10 differnt ways and most
of the time it made the circuit go haywire. the times it stayed normal,
i didn't achice my goal(the driver was still on). i sopose it would just
work in parrell withthe solar cell because it doesn't drain that much
power when it is not in use, but in solar apps. every little bit helps.

I am using the solar circuit powerd by a battery. my problem was that
when the motor turns, the fled is soupposed to turn off. mine stays lit
even when the motor turns. i found a way to make it stop when the motor
turns on,(grounding pin 2) but the entire circuti the dies because the
fled is attached to the enable/disable pin. Would detaching it from that
pin make it work?

7479 Tue, 9 Nov 1999 20:15:03 -0500 [alt-beam] Prefrances on Tutorials "Jim Taylor" I'm thinking of making a tutorial on some aspect of BEAM. Generally what do
people want to see?
