To all, the recommendations to date:

1) change MOSFET MIC4422 to IRL510 (IC4,5,6,7) to handle larger load and eliminate 8.5 voltage requirement
2) swap out A1015 for a Max232 to eliminate 12V requirement and allow communication with laptop via standard RS232
3) provide easy (and small) connector for RS232
4) use one 5V regulator
5) reduce MCU mHz if possible to reduce heat and power consumption

Mark,

What sensors are you using?  i.e. datasheets URL's on hall effect sensors?
