Hello All, Please check the following site. www.angelfire.com/electronic/hayles/charge1.html The schematic is on there, SW you have to make your own, cause he is not distributing it. BTW : Complete discharge is absolutely not necessary !!! This is one of the myths about NIMH's. If your algorithm is somewhat intelligent you can make a very good charger (if there was any car better than a Rolls Royce iw ould have used this comparisson) grtz Simon __________________________________________________ Do You Yahoo!?
