Introduction: How to Make a VGA Splitter.
In this instructable i will show you how to make a VGA splitter that can switch between two inputs or two outputs. this instructable is a modification of a printer(parallel) splitter.
Step 1: What You Need.
Here's what you need to make this:
-3 radio shack 15-position female VGA plug
-headphone style jack (female)
-multi. voltage DC power suply (3v)
Step 2: Beginning the Assembly.
In this step you will need to find a valid possitive and negative pin on the cable.
To do this you need patients and an ammeter.
On my splitter, pin 10 is the possitive and pin 20 is the negative. In order to find the pos. and neg. wires within the cable you need to clamp your meter to pin 10 or 20 (you'll have to do both anyway), then, after cutting the cable in half, you have to strip back each wire and, with the other cable of your meter, eliminate each wire until you've found the one you want. then do it again with the other pin/wire.
Step 3: Attatch the Power Jack.
now you need to attatch the power jack(headphones) to the possitive and negative wires.
first tin the wires then solder them onto the jack.
Step 4: Attatch the VGA Plugs.
now all you have to do is solder wires onto the VGA plug.
no order is needed but you will want to write down that wires go where.
Step 5: Finnishing Up
now all you must do is repeat step four on two more cables using the wiring diagram you wrote down.
cut off excess wires from cable.
We have a be nice policy.
