After about 5 seconds the screws stop, but I can still hear the motors trying to turn them. Currently I have no idea why they can't.\r\n\r\nThe L293 ICs are becoming quite hot, so I grabbed the first heat dispenser I could find in my assortment, it may be oversized but it should suffice.\r\n\r\n<a href=\"http:\/\/projects.schneidr.de\/files\/2011\/10\/P1070933_sm.jpg\"><img class=\"aligncenter size-large wp-image-126\" title=\"P1070933_sm\" src=\"http:\/\/projects.schneidr.de\/files\/2011\/10\/P1070933_sm-600x450.jpg\" alt=\"Heat dispenser for the L293 ICs, a little oversized\" width=\"584\" height=\"438\" \/><\/a>That's it for today, let's see what I can do about it over the weekend.","type":"rich"}
