Lightup pushbuttons/iPac?
RandyT:
Heh.
Sorry, I just got nervous when StephenH said +5v would light the lamps, just not at full brightness. I didn't want you try it to see if it was bright enough, because you'd only get one chance at it :).
Not knowing someone's skill level makes it impossible to forsee what they might try. Just trying to save someone from a punch in the wallet :)

The +5 V on your computer probably isn't even + 5.0 to begin with, it is probably 5.1 or 5.2. You usually have a little leeway with voltages, especially with simple things like lights.
I have measured voltages on working games before and found them off by as much as 2 volts.

Ah, ok. Sorry about that. Yeah, I'm pretty aware that exceeding voltage requirements is dangerous to the walet and patience. ;) Even though I've never burnt out equipment by doing something careless like that, I'm still careful. :) All I need are the testimonials of the majority of other people to convince me.
What I did before I started posting here was I did some homework on this until I hit a wall, then I started looking for a major bulletin board where I could ask some questions and share experience (and maybe get some ideas I never thought of before). If I seem a little talky or not newbie enough, it's only because I've been lurking at other boards and stuff. Nothing like diving in the deep end to learn to swim. ;)

Yeah, but better to be safe than sorry and have correct voltage. I might even put together something that'll accept an AC adapter or something (once I ask if that's feasable) with a power toggle switch. Rather than go from my computer's power supply (which would require a long cord that could get caught on things if I decide to make a podium of some sort). But I'll go with the driver circuit diagram just to be on the safe side (in case the AC adapter thing isn't possible noway nohow).
BillyJack:
Doesn't Happ have LEDs "kits" that fit for their lightup pushbuttons? Thought I saw that somewhere on their site long ago...
(Sorry, this thread is so confusing I don't remember what the original question was.)
;)
Edit: Idunno, this comes up when you click on the LED Optional link in the lighted pushbutton page.

Not sure if the power reqs are too high for the ipac still... just rambling i guess...
Edit 2: Aha! they come in 6v form (obvious if you read the page unlike me)... i guess the 5v would power them a little dim, huh?
