External Power Supply Info

**dvanteslaar** · 08-09-2007, 08:57 PM

I am trying to procure an external power source to drive the LEDTRIKS board, and am having a difficult time trying to put together all the pieces of information scattered throughout this forum and the LEDTRIKS manual.

I have finished building the LEDTRIKS PCB's, matrix, a wooden case to mount the matrix in (which is also covered with a piece of 3/16" plexiglass), the interface cable, and have just completed wiring up the anodes and cathodes to the PCB (which is mounted inside the wooden casing). I now need an external power supply so I can fire this bad boy up!!.

Ok, so far as I can tell, I need a "filtered" and "regulated" 5 Volt DC external power supply capable of providing at LEAST 3 amps at 5V DC....I DO NOT want to power it off my laptop power supply, so can anyone provide me with some more detailed information on where I could obtain something like this??

Thanks -

David

Not fair Wayne, you don't take the time to properly format your links so you get the post in first. That's not playing nice. I think you should take a time out and practice your URL links a little

PS, I absolutely love your sig!

Wayne,

Thanks for the information, but I must confess that stripping out an old psu from an old computer and then hacking it together to produce a bohemian psu seems a bit archaic to me, not to mention that the finished product is too large to be self contained within any reasonable sized casing!

THE LEDTRIKS board I have built will be mounted (and used) on a wall in a K->6 school and I cannot have a monstrous psu laying around outside of the LEDTRIKS cabinet!!

So, is there any other option available to me for powering this thing up? I would really hate to scrap the project after the time I've put in to it, but again, the finished product must be self-contained (including the psu) and away from the hands of little children.

Please advise -

David
