Essentially I have a 12 screw terminal strip, four of which are used for power inputs (A and B redundant). Not really room to change... plus the other design is done. The measurement is done on the power inputs themselves. So, really I'm faced with either just regulating it... and measuring the voltage another way (which is definitely possible), or doing something creative with scaling the voltage input to the device. Which means the divide by half regulator. -forrest -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
