light up translucent trackball
AlanS17:
Well it's a matter of physics. The density of the ball in this situation is almost negligible as far as speed is concerned because even the heavier ball will reach its maximum speed in a spin. Even the heavier one is light to enough to machieve max spin. (Though it may be easier to spin the lighter one anyways.)
However, the heavier one will achieve greater momentum and therefore keep spinning longer after you release. (Newtonian physics.)

Whilst on the subject of lighting trackballs I also want to light my 3inch translucent (Blue) Happs ball. I

Part no.: L-53MBD

Light output: 40mcd

How many? Of the one above? Well, twenty, thirty?
Maybe you should get a BRIGHT LED-type! ;)
Bright LED's have usually 2000mcd and more. (also depending on the color you choose) You don't wanna use a 40mcd-LED for lighting anything up.
GSXRMovistar:
These were the ones they had titled as High Brightness!, They do have some brighter ones ~2000mcd but not in blue :(
Anyone know where I could get these in the UK?
Thanks.
Carsten Carlos:
I got 2000mcd blue LED's from a mailorder here in Germany. Other colors go even higher! I'm pretty sure there must be some kind of electronic mailorder in UK, too - just search the web for it. :)
