Powering CMUcam without full-size RC?

[Mike]

I’m taking the CMUcam home tonight for some testing. While I’ve been at our school, I’ve been using the '04 robot to power the CMUcam. However, I obviously can’t bring the whole robot home to test the camera. Will the camera be able to be powered off a Robovation PWM port? If not, is there any other way to power it without a full size controller?

Thanks.

Yes, the EDU-RC works fine (the code was developed on a EDU-RC).

Edit: Er, wait, I just remembered that I modified the CMUcam2 attached to my EDU-RC to derive it’s internal +5v from the EDU-RC’s +5v supply. So, I’m not sure if the +7.2v is available on the PWM outputs.

I simply use a 9 volt power supply I had laying around from some old device. Radio Shack, etc. has the male versions of those power plugs available to accept soldered wires.

If you happed to have old “brick” transformer power supplies laying around, they can come in handy for easy, (more) portable power.

Yeah, the EDU-RC works OK to provide power through the PWM output. For the demo unit that I used during the kick-off, I used one of the IFI mini-controllers, which is internally nearly identical. On that unit, power was pulled from the “PWM Out” header on the mini-controller and routed to the camera.
