>A circuit like the Black regulator (less than $5 in parts) >or a module (less than $10) would be fine. Hmm, have a look at the Linear Technology regulator modules. Not sure if they have a high enough input voltage though, and they also appear to be BGA. http://www.linear.com/ad/micromodule.jsp -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
