    Opencockpit servo card ?

    I recently purchased a usb servo card. I'm going to try my hand at building an airspeed gauge.

    I was wondering what is the best/simplest 5v power supply to hook up to the card?

    Thanks !

    Re: Opencockpit servo card ?

    We use the PC power supply, extracting the cables trough the unused CD-Bay. From any molex conector to de USB servos card (soldering directly the cables to the conector of the card).

    Just a tip: Be carefull with the servos conections and read the instructions manuals for the properly GND-SEND-RETURN. I conected one of my servos to the card in inverted order by mistake, and the servo burns in a second!

    Thanks Aaron ! I will give that a try.

    I have an old power supply . I guess it would be a fan connection I could use ?
