wow great minds/stoners must think alike
I was planning on doing the same when I find one at a garage sale or auction cheap.
there are several ways to do it.
timed
switches at both ends
or others im sure but to ripped to think about it. just mixed strawberry cough and a outdoor sativa bagseed that kicked ass. rolled it all in one spliff and man it tasted weird. good mix.
anyway back to the idea.
if you had a switch that it could touch at both ends it could send it back the other way. or on a timer with a relay/contactor
and maybe some sort of delay before it started moving back the other way.
or put on some sort of motor speed control on it running all the time just real slow. that would probly be the best way so you could adjust the speed the lights moved.
Im also thinking of a light mover like a big celing fan that could rotate 4 lights or more , just by powers of 4 since you have 4 blades like a fan. (4,8,16) unless i did a 3 blade or 2 blade system. anyway the wight of the light or lights would have to be even.
throw me your ideas and maybe we could combine them or something.
thats the best part about this site , everyone is helping each other out. I love this site, I think my ol lady is getting jelouse
