I originally made a mistake in my wireing and am curious if I somehow "fried" a circuit? I've since tried several combinations but nothing seems to work. I tried to draw up a small sketch as to how I wired my bot. I posted it over on my flickr account (though they don't like hand drawn sketches so if it's not there when you click the link below they probably pulled it.) http://www.flickr.com/photos/cyenobite/303787567/ Can someone who maybe succesfully wired their bot take a look at this and tell me if they see something I did wrong? I will bring it to the next meeting but I'd like to get it fixed before that if possible. Thanks for any input. I could take photos I suppose but thought the sketch would be better. Thanks Jef    Report

It is possible that you fried the 1381 or one of the transisters, but I doubt it. I will try and dig up an actual schematic for the thing, and if you bring it to the next meeting we can run a little beam clinic. Josh    Report

I recently got one of the solar rollers and now I'm hesitant to try it until I understand what I did wrong with the symmet. J PS> On a somewhat related note: I plan on makeing a small solder station this weekend. I saw that Bre Pettis had made his own "extra hand" using some armature wire and a block of wood. I plan on doing something similar with some scrap copper wire and a few alligator clips. If it turns out decent I'll bring it to the next meeting (and/or post some photos).    Report
