Broken Happ Trackball

<< < (3/4) > >>

...just remembered a trick (saw it on a hackaday.com post) to see if the IR LED is lighting.  The IR light wavelength is out of human eyesight range (I think), but maybe you can view it on some kinds of video cameras.  I think you need to use the the nighttime recording setting.  If you can see one then you should be able to see the other one.

I test mine with the viewfinder display on my digital camera.
You sometimes have to get the angle as claose to staright on as you can but it'll work.

Also old video cameras viewfinders do the same thing.

This is a quick and cheep way to test your remote controls too.

Well I tried it on another computer and it did the same thing.  Unfortunately I don't have easy access to a digital camcorder so I don't have a way to test the IR led.  Even if I could tell if the led was working or broken, I don't think it would matter since I couldn't do anything about it anyways.

I guess I'll start looking into other options, I'll probably get an opti-pac since its so cheap and I've worked with it before.

If the LED is bad on the trackball, how will an opti-pac cure this?
Doesn't it need to get the IR signal from the trackball?

I have the original arcade interface that came with the trackball, which means I would be completely replacing the broken part.
