hdd led thingy

[crazybillybob]

The xbox LED's actually have multiple colors in them I think, I've seen them be Red, Green, and orange.

If that's the case then they could change color with diffrent voltages.

How many leads do these LEDs have?

Take a read of this:

I think that will answer your question.

2Big,
as I think about the led light, the easiest way to do this would be a miccontrollor, that you would program. I'm working with a low cost ($9.00us) one that can be programed easly with your PC. I just have to post a q in there forum to find out if the logic is fastenought for what you want. The down side is the dude that answers these q's went into the hospital over the weekend (his apendix burst) and will be gone for afew weeks. I'll try and get you the info but it's going to take awhile. If this is ok let me know and I'll stick with it. If not that's cool too (I don't know your time table for this mod) just let me know so I don't have to worry about.

Good luck,
Crazybillybob

sorry for not posting the last 2 days i was working on my pc. (ill take some pics sone. ) eney way i have no time table. :p o i live in oz (australia). $9.00 usd thats about $15.00 aud .

crazybillybob - most basic-stamp type micro controllers are a smidge slow for that sort of thing, I've worked with them before. While cool, dont expect them to do anything in a hurry.

2bigfan, because you're in aussie, it's much easier to help you.

Take a look at this PICAXE controller for LEDs:

It should run at 3 volts, and the LED in it is a 4 lead RGB LED (I have a 4 lead RGB LED but not the controller. It might be perfect your project. I just don't know how to get it to run forever when power is on.....

Crenn,
You beat me! I've been looking @ the Pcaxe for another project of mine, but I wasn't sure if it was fast enough. The code for this HDD Light shouldn't be that hard (I don't know the lang. for Picaxe yet so I can give you all an Idea of what I was thinking) basically you set one pin to Input two Pins to Output. Setup a variable (for storage) when the in put goes high (IE light on) increase the variable by 1 then do an If input = high and Vari=even output 1= high if input =high and vari =odd output2=high if input=low output1 and output2=low.

The hard part is going to be setting up the loop cause you have to reset the counter (when it gets to like 1000)


I'll have to think about it more this is all just off the top of my head.
Let me know if you can do this stuff in picaxe land, (that way I can try it or stop thinking about it!)

wow this is much harder then i thought it would be . the only thing i have dong with codeing is makeing a small (****) game in gamemaker.

PP Mguire, green LEDs turn red if you put too much power through them. Are you using resistors with them? If not, you need to. This might help.

i think we've lost sight of the fact that what we're now talking about doing with a micro-controller could be done with 2 chips, small amount of wiring. Cheaper, simpler, probably more reliable.
