Any interest in a LED Driver board?

[Gamecab]

Hey All,

For the past week I have been toying around with the idea of producing an LED Driver Board similar to what Oscar Controls has listed as a how-to.

[RayB]

Damn, I got all excited cuz I thought you were talking about a board to illuminate different configurations of buttons, depending on the game selected.......

Click here -- http://www.oscarcontrols.com/led/index.shtml - in case people don't know what your taking about.

I'm interested, but it would depend on the price.

How is your Star Wars Yoke project coming along?

[Gamecab]

The price would depend on the interest really.

I would probably be interested (lots of lighting on my panels), although a simple 12V harness might be all I really need.  I think it's a great idea though!

[RoboG2]

Heck yeah.  I'll probably get one.

[ShinAce]

I've made my own, but I use 74ls04 inverters.
2 ic's worth a total of 1$, plus resistors+pcb. That's it.

I have my own board that I also created from Oscars Site, it works well and I like.  My general though is to just get the boards to the people who don't want to make the board or don't have the time to do it.
Now on the other hand, I'm really interested in trying to figure out a LED board that RayB was talking about.  That had me up late last night thinking on a solution.

That was called the L.A.M.E. Project.  I assume it died, because the website has been down for at least a year now.

I'm not familiar with this project.  What was it exactly?  Lighting up the buttons that would be active in a game, or something?  I'm planning to build something like that.  The easiest way for a hobbyist to do that would be interfacing the parallel port, maybe driving a set of shift registers to drive more LEDs than the number of I/O lines being used.  I'd rather do it with USB, though.  I've never had much luck interfacing with the parallel port.  The software's probably the harder part.

I think the board's a good idea for people who want a quick solution to driving high-current LEDs or lamps.

I would be interested.  Let me know when you are ready to move this.

Gamecab, if the price is under $20 complete.  It'll probably get one.

Here's a post about the LAME project

Announced in February 2004 and disappeared in March 2004?  Didn't last long, did it?  Did they ever accomplish anything?

[Gamecab]

Gamecab, if the price is under $20 complete.

 I think the reason that one costs so much is because it uses #555 lightbulbs.   

 Im guessing its easier and or less costly to control leds
rather than lightbubls.

[cholin]

Depends how much functionality it gives.  If you're doing the one from OSCAR, well, maybe.  If you're adding a few small features, then probably.  If it's possible to connect MORE leds, most likely.  What I planned on building was something following those guidelines, using power from an iPac to illuminate around....let me count...up to fifteen lights.  Id rather build my own though because it saves me the cost of a PCB that is really just a waste when I can buy a breadboard for two bucks.  If the shipping cost is OK, then I will CONSIDER it.  Other than that, it seems like an awesome idea, but a waste of money to me.

That Arcalux product is cool, but did you see the price tag???

You can control up to 8 LEDs directly from a parallel port, but I find that kludgey and potentially dangerous to the computer. Plus, you need more than 8 LEDs on a two-player panel..

IMO the L.A.M.E. project is dead.

So, in my quest for the hall of fame, I'm going to design my own circuit which will control up to 16 LEDs, then I'll integrate the control software into my build of MAME so that the appropriate lights will light up when each game is played. Maybe if it is cheap enough I'll manufacture some and sell them.

[cholin]

Im trying to do something like that too!  I dont plan on controlling it through MAME, but rather it lights when a certain switch goes off.  The only downside is that its going to take a ton of wire because each switch needs power, which then splits to a switch, which then goes to the LED.  It will be cool though.  If your board is cheap Ill look into it.  Maybe supply the schematic if it works well, Buddabing?
