Warning

A word of warning in regard to the openegg2 control device circuit design: Today I found my openegg2 unit smoked. So far I can tell the L5973 and the GSM modem are both fried. I do not know what exaclty the cause could be, but obviously the design has a flaw. Luckily a 3 Amp fuse blowed up and nothing else happen beside a bit of smell.

So you have been warned. This design and any other might burn up your car, your house, cause material and personal loss etc, USE AT YOUR OWN RISK !
