Hey guys,
Was curious on what you used for a power source. Did you just connect it straigth to a molex connecter in you comp, or did you make a little box with a battery. Please let me know. I am trying to figure out how i want to do the "power source". Thanks

Best way in my opinion is to use USB for power. If you want to have totally independent pad, use batteries.

Any tutorial on how to hook it up to the USB?

simply speakin, usb=5v. so red wire is + and black wire is -, also the shielding isnt needed. lol. not really much of a guide, but, it should help.

You can get spare USB cables for scanners etc. from computer component/office stores. Cut away the end that gets connected to the scanner and locate the wire with +5 and ground. It is easiest to do if you have a multimeter. Usually +5 is red or yellow wire and ground is thin black wire.

i measured mine and usb is only 25mA, so wouldnt that not be enough for more than one LED

How did you actually did the measurement? I'm pretty sure that you didn't do it right.

ill try again, i used a didgital multimeter

ok, now i know why, know it reads approximately 500mA, the first time i used the 400mA max socket and it wasnt an accurate reading, this time i used 20A max socket and it read right
although i did get a USB port power surge warning that cut off power to my mouse too so i had to restart because i couldnt reset the port without the mouse

The reason why I asked is that you should not just stick your multimeter between the +5v line and the ground when using the ampere setting. This is because the multimeter represents a short circuit to the port if you don't use anything to limit the current. That is why you got those warnings from your computer. When measuring amperes, you should always have something to limit the current like a resistor or a complete circuit that you then connect in series with the multimeter.

So, in short; NEVER CONNECT THE MULTIMETER ALONE TO THE POWER SOURCE IF MEASURING CURRENT!

In short part two; YOU CAN'T MEASURE A POWER SUPPLY'S ABILITY TO GIVE CURRENT WITH A MULTIMETER ALONE. YOU CAN ONLY MEASURE THE VOLTAGE!

ok, thanks for the warning, guess ive learned my lesson

I've got mine powered from the usb with 2 uv leds and works perfectly.
