Title: Translucent Happ Blue Trackball too bright?
Post by: AMDman13 on September 23, 2006, 12:46:26 am

Am I the only one out there who can't stand the glow of that ball when the room is dark and I'm trying desperately to beat my children at Galaga?  :D

Has anyone tried to hook the 12v to the 5v molex? I'm looking more for a glow instead on a full-on beamer.

Mine's lit by an LED and it's just right.

You could always use a potentiometer as a dimmer.
If you want to get technical there are circuits that will dim based on the brightness in the room.

Yeah, I'm personally hoping that whammoed gets around to releasing these:

Offsetting the LED will help.

I am not using an led just the standard 12v lamp form Happ.

From what I've seen here... It looks like using an LED will actually make the trackball brighter which is what I don't want. I think I will try underpowering via the 5v and see how I like that. Personally I like the way the ball looks not lit. I think with using the 5v it would look not lit in daylight, but when dark it would give a very mild glow.

use a higher voltage bulb or like you say hook up the +5 to the bulb instead of the 12-if that bulb is really bright its possible happ put a +6v bulb in there(i've seen it done before) by accident

If the 5 Volt is too dim, you can also feed it with 7 volts by connecting it between the 12V and 5V (12-5=7) volts.
