Super bright LED driver board for I-PAC
<< < (3/12) > >>
SirPoonga:
I have another weird anomoly.

When I had a computer in my cabinet the leds worked fine, both keyboard and ipac.

On this machine however, the keyboard leds don't work (not surewhat would happen if I hook up an IPAC).  The lights work when I press caps lock, etc...

Oh well.

Thanks for the comments, guys!  I figured that more people must have been making these since super bright LED's seem to be the fashion lately, but Carsten's site was the only one I've come across so far that actually showed how he did it.  That's one reason why I documented mine like I did (with a colored diagram!   ;D ).

Hmmm, strange problem, 1UP.  Like Carlos says, if they work when you push the keys on the pass-thru keyboard, then I would suspect it's a software issue...   ???

1UP:
Well...I figured it out late last night.  Plugged the I-PAC into my XP machine, and the LEDs worked.  Guess it's some issue with Windows 2000.  Only thing I can think of is to install XP on my cab again...  (Guess that's why it used to work.)

One weird thing that still happens:  when the LEDs blink, the keyboard ones blink at regular intervals, while the I-PAC ones randomly miss blinks (the LEDs stay on or off steadily for 2 blinks.)  Is this normal for the I-PAC?  I could swear that when I got it, the blinks were nice and regular...  Maybe I've done too much experimenting with it?

Oscar,  Thanks for the excellent write up.  So far I have only wired up the Player start buttons.  Looking at this has re-motivated me to add the rest of the lites to my panel.

Oh and thanks for the plug!
MrBond:
Wow, thanks Oscar, this has sparked an interest...eventually I'll have to try the LED deal.
Those buttons just look so cool!!
