    My Robot Project--Power supply

    hi moebious if you will wire them in series you will get 18V, and then regulate it down to 5v you will only create more power loss if you will wire them in parallel, you could decrease the batteries internal resistance thus making them last a bit longer... I wpuld suggest you to wire only one...

    Switching circuit

    you could build one yourself quite easilly... what i have in mind is a sort of a relay, which when activated will move the contacts, but when deactivated there will be a tooth that will not allow it to come back... the only way to return it will be manually.... hope i was helpfull

I am using a dual 12v seperate switching supply. one of the outputs is for the UC3843 and fan. the other is for secondary side supply. So does the usage of the seperate supply mean that i can reduce the output down to 0v and not...

    0-30 Vdc Stabilized Power Supply

    well... I guess you are right... my problem is that I have nowhere to buy another transformer... the one I have right now (center tapped 24v 4.1A) was found on a sidewalk I guess I'll just build one and wait till another transformer rolls into my hands
