Mary B:
Batting zero on that part number... maybe contact the board manufacturer and ask them?

ontfarmer:
Update  There has been very little sun here since last fall  ( kind of depressing )  We are starting to get
 a few sunny days now.  I'm very happy with the increased power from the panels tracking the sun.
I have been adjusting the tracker to follow the sun.  Installed a battery to power the actuator going to try and get charging from the panels.

OperaHouse:
I haven't been able to find that IR module in an old VCR.  I did just find a stock of photo transistors while searching for something else.  These should work as a repeater for anything.  It will just have to be shielded to keep out outside light because it won't be able to filter out ambient light.  That shouldn't be a problem.

ontfarmer:
That is great you found the photo transistors.  I have been pointing up the stone foundation on the house, picking up limbs, the usual spring clean up.  Sometime when you get a chance I will try to get that working.
