Hi! I remember I read some article, maybe on Elektor, maybe not, for a circuit booster that allows to use just 4 AA rechargeable batts in a holder for 6 AA, using the spare space for the circuitry. As I cannot find it now, does anyone who read it can tell me where was it published?, or can suggest a link for another schematics or a booster chip for this?. Better if it takes care of not to deplete the rechargeable batts. Thanks in advance, Diego. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
