Home Made Usb Power Hub (made for Usb Hdd Disks)




Welcome to my third tutorial.
This time I'm going to show you how to power up your usb disks! :)

If you got a pc with a thirsty graphic card and a low power source you may be suffering random crashes or even
not spinning usb hard drives.

Making such a hub is fun and easy. It will cost a few dollars (without power supply)

Also many people were telling me that my disc is broken...It works perfectly now!

What problems?
-disk freezing
-disk beeping
-disk do not spin up

What do you need?
-pc power supply (don't buy a new one just get on from scrap . In my country they cost like 4$ ea.)
-all the soldering stuff (iron, etc.)
-cables (ribbon cable just 4 wires)
-led diode
-470 ohm resistor
-usb plug + socket
-few minutes
