Have you sent pictures and a schematic of the ebay? We might be able to suggest some wiring improvements to reduce interactions between the two boards, if that is indeed the problem. If so, we'll also try to figure out how to fix the system so it doesn't happen even with the original wiring. -- [email protected] _______________________________________________ altusmetrum mailing list [email protected] http://lists.gag.com/mailman/listinfo/altusmetrum
