Step 7Modify the hub
I wanted to power my hub directly from my computer's power supply, so i had to modify the hub a bit:
I took out the fixed voltage regulator (if the 5volts from the pc aren't clean enough, i would have other problems than a not working hub) and soldered the wires directly to the outputs of the fixed voltage regulator.
My hub also needs a bridge (isn't visible on the picture, i bridged it with a small piece of wire on the other side of the pcb) between the in-and output so the hubs "knows" an external powersource is hooked up.
In- and output was labeled on my pcb, if yours isn't labeld, take a look in the datasheet of the regulator.
I also removed the old power jack to have a place to wire up the leds later... But if you are not 100% sure, you could simply connect them to the cable...All the exact places to solder depends on which hub you use, if you're not sure, feel free to ask...
