The circuit is not simple and would be hard to describe without schematics. The simplest approach would be a 555 timer driving a 5 volt DPDT relay. You can get cheap relays surplus at sites like Electronic Goldmine. Or if someone is knowledgeable about electronics they can use transistors or FETs in an H-bridge configuration. - Steve N

I looked in the archives but I must be blind. Thank you. John. John NOT-BLIND and message from last Tuesday (5 days ago) is valid and should be Brought Back into CIRCULATION, as this is something that was/is ON-TOPIC! Just curious, are there actually any members on CS-LIST... that can HELP John?
