Double your productivity by connecting a single mouse to two computers! It's simple: one mouse, two USB connections, infinite possibilities. Each click of your pointer finger will be twice as powerful with this mouse mod. This is a low cost, no soldering, HOW TO that will double your clicks per hour in minutes.
Step 1: MATERIALS / PARTS LIST
Vendor: Radio Shack
Cost: $9.97 or less
Notes: You only really need one mouse but you need two serial cables. I ended up just buying an extra mouse because at RadioShack they are cheaper then a serial cable. Old serial mice are just llaying around everywhere waiting to be used, they can often be found on ebay.com for $1 or less.
Part: QVS USB-PS2Y USB to Dual PS/2 "Y" Converter
Notes: You are going to need two of these. There are cheaper options but this is the only one that I know works for sure.
Part: Duct tape
Vendor: Any will do.
Tools: A sharp Xacto blade and/or wire cutters.
