I was looking for a usb switch with 1 input and 2 outputs, so I could switch my usb hub with mouse and keyboard between my PC and laptop. Didn't found it cheap enough so I decided to built one myself.
Step 1: Materials and Tools
- 2 usb extension cables € 2,50
- A small box (could be metal or plastic) € 3,00
- 4 dpdt switch €10,00
- Soldering iron
- Stripping tool
Step 2: Drill the Holes
Draw the positions for the cables and switch, drill the holes.
Step 3: Cut the Wires
Cut the usb extension cables the length you want, I recommend not longer as 2 meter, you might experience interruption of the signal if you make the cables longer. You need 2 cables with male to connect your PC and laptop and 1 female as output. (I had the black cable lying around so I used that one instead of the other side of one of the usb extension cables)
Put the cables trough the holes.
Step 4: Solder the Wires to the Switch
It doesn't matter wich sequence you solder the cables, as long you solder them al three the same. The switch is an on/off/on, I recommend using this one instead of a on/on because when you switch there may be short circuit between the two inputs.
Step 5: Finished
Now you can switch easily between PC and laptop without needing to unplug and plug it in again in your other device.
This is my first Instructable, so sorry if I'm doing it wrong and sorry for my bad English :p I'm from Holland.
