  14. Concerning the 12V to 0.6 V issue, I thought I would throw my two cents in.
  15.  
  16. I would go with the LM317 approach as someone previously suggested.
  17. However, since the car battery does swing over a couple of Volts, I think
  18. that regulating the battery voltage to 5 Volts with a 7805 (Bt suffix should
  19. suffice) would probably give you a little better performance.  I use such circuits
  20. at work when I need several precise voltages for cicuits when using one common
  21. AC - DC power jack instead of several power supplies.
