hi all,
can any body help give advice on a charger i built. heres the circuit.
Automatic 12V Battery Charger : simple electronics
The only thing i did instead of using one ic lm393 i used two ics, its a bit of a ***** to do the pcb layout with all the transisters running to one chip so i thought to use 2, each using the same supply,so instead of using the ic as a dual i used it as a single. does this all make sense.Also i did not have a 15-0-15v tansformer only a 0-16v.The whole circuit does not seem to work as it pushes out nearly 22v out (no load) and when i connect a battery it keeps charging at 16+v.

guys ill try put the pcb here, hope it works.
