DOUBLE MOUSE

intro
 

introDOUBLE MOUSE

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.
DOUBLE MOUSE
 
 

step 1MATERIALS / PARTS LIST

Part: PS/2 Mouse (serial) Vendor: Radio ShackCost: $9.97 or lessNotes: You only really need one mouse but you need two serial cables. I ended up just buying an extra mouse …


step 2CUT CABLES

- Cut one mouse cable at the midpoint. - Cut the second mouse cable an inch or so away from the mouse. This mouse is no longer needed, hide it in a drawer for later us…


step 3EXPOSE WIRES

Inside the serial cable you will find smaller red, black, white, and green cables. Cut away 3/4" of the outer rubber and twist the exposed copper for each of the individu…


step 4TWIST AND TAPE

Twist together groups of three wires consisting of the same color. Tightly wrap them in tape so that none of the copper is showing. If you have a soldering iron handy you c…


step 5WRAP CONNECTIONS

Once all four groups of red, white, black, and green wires are wrapped together tightly wrap them all in tape. When you're done you should have a dirt style Y cable.


step 6CONNECT USB ADAPTERS

Connect the adapters to the serial cables. The connection for the keyboard will just remain empty for the purposes of this tutorial (yes, I'm leaving room for the DOUBLE KE…


step 7USES?

9 to 5 PaintingsThere are many possible uses for the Double Mouse ranging from useless to pointless. The first series I have done using this new technology is the 9 to 5 Pa…


step 8THINGS THAT DON'T WORK

The smaller PS/2 USB adapters didn't work for me. I'm not sure why this is but if anyone knows please feel free to leave a comment. A common error for a non-functioning Dou…

I just wanted to point out that you repeatedly said serial mouse. While technically these run over a serial bus, they are not considered serial mice. They are PS/2 mice. A serial mouse would have a DB9 connector on it.

Although I do give you points for a good instructable!

i have an idea. have you ever had two computers, and wanted to put a document on both of them. you dont have anything tho take it from one to the other to have it on both. so, ou use this concept, but with the keyboard. you put word on both computers, then type. you only have to look at one screen. this is because if you made a mistake on one, it will be on the other. you can also do the mouse, so when you click somewhere, it will click on the other computer. thats what i call killing two birds with one stone!

or you pay £5 for a memory stick instead of mutilating a set of computer equipment, and taking longer than it takes to transfer a file :P

good idea all the same.... lol

now I wana hook up to mice to one computer
Apr 9, 2009. 7:10 PMMadrias357 says:
done it. Doesn't do anything cool.
Sep 6, 2008. 7:26 AMDerin says:
PS/2 is not hotpluggable,even on USB.the BIOS only checks for the mouse at startup,and that is why it wont work
Feb 26, 2009. 2:16 PMbwpatton1 says:
ya this is frustrating when you are working on computers and forget to plug into the mouse, then you have to turn off the computer restart etc.....
Sep 18, 2008. 8:21 AMcollard41 says:
complete rubbish. the mouses drivers are installed (or are already there) when plugged in so you di not have to restart your computer
Sep 18, 2008. 10:07 AMDerin says:
meh.it does not check for new equipment unless you restart,I tried it by trying to plug my USB mouse to PS/2 with the supplied adapter,it did not regocnize the PS/2 compatible mouse
Sep 18, 2008. 3:23 PMtristan993 says:
this is a nice instructable but u could also just plug a keyboard and mouse into a usb adapter strip and plug that into a computer, and when u need to use the other computer just use an extension usb cord and plug that into the usb adapter

This is such a genius idea that, if only you hadn't posted this idea for free on this site, I'm SURE you could have made a WHACK of money off a grant from the National Endowment for the Arts. But, you posted it for free on the Internet, so no taxpayer-funded art money for you! ;-)

Does anyone know how to make a PS/2 USB adapter?

There's an instructable on it

Haha those 9 - 5 drawings are great :P
May 27, 2008. 5:00 PMEnigmaMax says:
couldn't you just connect two monitors to the computer?
Jul 8, 2008. 9:37 AMSpencerr says:
the whole point was to work on separate computers.
Apr 22, 2007. 10:59 AMSullen70 says:
I appreciate the 9-5 paintings as 'process art', but I think any UI/human factors specialist might retrieve some value in the images as data. Clever concept.
Apr 24, 2008. 9:38 AMjeffconnelly says:
no, I think it's pretty secure, seeing as you can't tell when he put each dot on the screen.

May 21, 2008. 8:07 PMpatricksanford says:
actually, it can help ergonomics. the the more "dense" the image, the less he had to move the mouse, the less dense, the more he had to move the mouse assuming that the paint program was set to trace all mouse movements. it could be useful in designing GUI's in a manner that can minimize the need to move the mouse about, and thus help to avoid repetitive motion injury. set it to track the density of mouse clicks and you might be able to find out which tools in a program are used the most, and lessen the number of clicks needed to access that tool. lots of uses for this actually.

CPU = central processing unit
Motherboard = main board that everything connects to including the CPU
Monitor = the visual interface (the screen)
Computer = housing for the motherboard, drives, and component interface cards i.e. the video card.

i hope that cleared things up.

also you may want to only connect one set of power wires to the mouse. right tnow you are giving it double what it needs and that aint too good. atleast you had pictures so PROPS! =D

Mar 19, 2008. 9:57 PMn0ukf says:
Connecting the power wires together doesn't double the voltage going to the mouse, so the mouse won't be bothered, but the regulated 5v from the two computers might not be exactly the same and try to fight each other. Though being on the USB ports, that fight would be limited to 500mA or less. Doubling the current sources won't hurt the mouse, as it will only draw what it needs from the available 5v supply. Now if you tried to feed the mouse 10v or more, then it might get heart burn and die on you. ;)

no no no its

CPU = brain
Motherboard = spine
Monitor = the visual interface (the screen)
Computer = skull or body!

i was going to suggest synergy. it's pretty neat
May 31, 2007. 3:43 AMSquee says:
I've used realVNC before, I might have to give synergy a try. I tried to do something simlar using a demo of a pay program but it never worked and I wasn't willing to shell out the $80 for a full copy+tech support when I could use realVNC for free. Although what I was really looking for was essentially a software KVM switch.
May 21, 2007. 2:15 PMheav says:
yeah, I just don't understand how fi5e does control in which computer he wants the click, since didn't saw the switch part, still, software controlled mouse/ keyboard is much more elegant and practical than messing around cutting cables, etc... but any ways that's for real use, this approach is for creating some kind of strokes logger, mmmm still some software from synaptics touchpad can do the same.

step 8"
reason it did not work they come with certin duail usb/ps2 mice
May 14, 2007. 1:59 PMearthstation says:
this is certainly an interesting project. i think i might just have to go make one sometime...
Nov 30, 2006. 11:45 AMrandofo says:
Soldering! It's the future.

Pretty awesome. Have you tried this with a keyboard yet?
Dec 5, 2006. 2:35 PMzachninme says:
Double keyboards would be stupid to hook up to a single computer, as it would double your strokes, or do nothing new...
Nov 29, 2006. 4:51 PMGrendel says:
The reason the small adapters don't work is because they are just connector converters and you can't have 2 USB Hosts on the same bus. The larger units interpret the PS/2 signal, reformat the data into USB HID packets, and send them on to the PC. The reason you can split the PS/2 mouse this way is the clock and data come from the mouse. The only time the PC sends data to the mouse is at startup, and if you have some special drivers for the mouse. Since the adapters mask the mouse, theres no data going from PC to mouse. Not very useful of a hack, but interesting non the less. Good work!
Nov 30, 2006. 12:54 PMMyself says:
You should still be careful, since this arrangement bridges two PC power supplies. If one machine is on while the other is off, badness can happen. If they're plugged into different outlets or otherwise don't share a ground reference, badness will almost certainly happen.

Amazing pictures, by far the best i have seen on Instructables. I like the mouse, very clean and easy, and i have GIMP too =]

Nov 27, 2006. 11:43 PMtheRIAA says:
those pics look surreal! what kind of camera do you have?
Nov 28, 2006. 2:03 PMClevinger says:
He's shooting natural light with a fast f/stop; like f/2.8 or lower. The blur you see in the background is known as bokeh. He probably has a tripod and is doing a pre-metered, delayed shot.
Nov 28, 2006. 10:32 PMtheRIAA says:
f/stop has nothing to do with speed, and thats not what im talking about.

Im talking about how he has crisp, perfectly colored pictures, with eerie lighting that look like their photoshoped (but obviously arnt).

must be the lighting... which is a lamp, and is in no way natural

Nov 29, 2006. 8:05 AMpaanta says:
A large (physically, small numerically) aperture does get referred to as a fast one, because you can use shorter shutter times. So yes, he used a fastish f/stop.
Nov 28, 2006. 1:07 AMCrash2108 says:
Some of the things almost look superimposed.

I also see a lot of scrolling in those pictures.
Nov 29, 2006. 4:11 AMwestfw says:
The small adaptors don't work because they don't actually convert PS2 to USB; they're just "wire rerouting" for a mouse that has the internal ability to speak either USB or PS2...
Nov 28, 2006. 4:04 PMMadBeaver says:
it looks and sound really cool.
is their any other advantages to this besides your art?
again, very cool
Nov 28, 2006. 1:09 AMCrash2108 says:
Oh, and I guess it would also serve as a visual mouse tracker/logger.
