How to poewr the light bulb on my Happ Track Ball?

If you want to go usb, I picked up a couple of these USB snake lights for dirt cheap and used them.

They're very bright and pretty much the easiest thing you can do to light a trackball.



Although, hooking up 12v isn't terribly difficult either.

shateredsoul:

the light bulb isalready attached under the trackball, it's not connected to a power source as far as I can tell

surface tension:

I'm not aware of any official Happ illuminated trackballs, so where did the illumination kit come from... or is it really just a bulb poking through the hole? Did it not come with instructions?

By far the cheapest and easiest way to illuminate Happ trackballs is an LED and a resistor, connected to the 5V on the control board.

Smeghead:

12v AC Adapater, 5v USB power isnt good enough to shine through a ball, I tried it

See, there's the problem.  You will need to connect the light to power to get anything visible out.
