    FS: Low Level Relay pack

    As some of you know, I've been integrating my A/C with my carputer. I ran into a problem, though. The Phidgets 8/8/8 kit only allows 20mA per output....not nearly enough to turn on a relay.

    So, I built this:





    It will respond to as little as 2mA of current on each channel, closing the relay. This makes it suitable for use not only with a Phidgets board, but also a parallel port.

    It's also pretty cool that the relays have built in quick disconnect connectors, so you can change what the relay controls without re-soldering.

    I used 5 relays, 1 for each fan speed, and one for the compressor. Each relay is rated at 25A load.

    You could control windows, doors, lights, and your A/C with this...


    I have 2 these, but only need one. I'll sell the remaining one for $25 shipped.

    So, this needs a Phidgets to work? You mention it could work with a Paralel port, do you know of a place that has sw to control the paralel port to control the relays?
