This Instructable will give you step by step instructions on making a very cheap ceiling mount for a wiimote for use with a ceiling mounted projector. This works great in class rooms or board rooms where the projector is permanently mounted on the ceiling.

First lets get everything together. Here's a run down of all the items you'll need:

1 - 12inch shelf bracket
1 - dollar store mini tripod
1 - 3v transformer
1- 1/4 flanged hex nut
1 - 8/32 X 1" machine screw
2 - 8/32 nuts
1- PC slot Blank
2 - standard wire ties

Some tools you will need:

Philips screw driver
Hacksaw
Drill
Wire cutters
Electrical Tape

The hardest thing to find will probably be the 3v transformer. I got mine from a bunch of wireless access points that are being powered over ethernet so we didn't need the transformers. You can most likely find one on eBay or at an electrical supply company.

Step 2: Preparing the Wiimote Battery cover

Before we can mount the wiimote we have to make a few modifications to it. Start by taking the jacket, strap, and battery cover off of the wiimote. Now flip the battery cover over there will be some thin plastic lines that make a rectangle. In the middle of this rectangle you should make a dot. This dot is where you're going to drill a hole the size of the hex part of the nut, but smaller than the flange part. I usually start with 3/8 drill bit then ream the hole out with a pocket knife til i get it the right size. The hex part of the nut should be hard to push through and fit tightly once you get the hole the right size. If it is too loose you may want to add a little glue to hold it in place. Now you have a battery cover with threading. You can use this to mount the wiimote on a tripod if you like, but were going to permanently mount this one so cut a small notch in the cover on one side just below the nut. Set the cover to the side we're done with it for now.

hi do you think it works well when its mounted with projector as i believe when using white board if your IR led is hidden it wont send signal to wii remote.
Or do you thinks its the best place to place it
thanks

I think the point of mounting a wiimote to a projector is to fix the position of the wiimote so you don't have to recalibate everytime.  In that case, you can use the software like iWiiBoard to run the calibrated wiimote whiteboard automately with the startup of your system.

I may be naive, but what precisely is the point of mounting a wii mote to a projector??
 Create an interactive whiteboard
 I wasn't sure either! This might help explain more...

This is great, I've been exploring options for wii mote deployment at our school for a while now. This is a perfect and cheap solution!

Thanks for posting this. :)
If you mount the Wii mote on the wall perpendicular to your "white board" instead of directly next to the projector you will not have to stand so far to the the right or left of your pointing device.  the calibration step in the set up of your white board will take care of the strange angles.

Very useful! I like the idea of the power supply and the way turns wiimote to discover mode.


Nice wiimote stand... it looks professional. what percentage of the screen do you cover? for the power supply I just hooked a usb charger to a usb charged battery... it is taking in 5 volts and using 3 so I am sure it is not good for the memory of the battery, but hey... seems to work.

Cool, however there is a flaw in your idea. Consider the way someone stands when writing on a whiteboard, typically, they stand in front of the text they are writing, so this would obscure the IR light coming from the back. The angle suggested by the original project eliminates this, you need to find a workaround (rear-projection maybe?)
but the whiteboarding they will do will be 'invisible' until the projector sees it - so they will be forced into a stance where they're drawing outside of their own shadow.
How well does it work considering its not at an angle to the projector? I thought you needed it to be at decent angle to the projector if it isn't projecting straight down onto a table or something like that.
how well this works would depennd on ones hand position. If your hand blocks the IR LED then this won't work. Optimum positioning is on the left side of the board at a ~30 degree angle from the wall unless you are left handed.

I forgot to mention since this is a shelf bracket you could mount the bracket on a wall, it doesn't have to be with the projector just don't cut the elbow off. You could mount to left or right of the screen.

It works great so far we have them mounted this way in 2 computer labs and a classroom. You just need to stand a little to the left or right of your pointing device and there's no problems at all. A class full of 4th graders were using it the other day with no problems what so ever.

I guess a wilmote is some sort of remote for controlling the projector, but I do not know. You can also adapt other power adaptors for 3 volts output. Just go to Radio Shack and get an LM317 variable voltage regulator chip. There are many sets of on-line instructions for how to configure it for any output you want. The one requirement is that the power supply you are adapting must have an output at least 1.2 volts higher than your desired final output of 3 volts.
I think its used in some sort of tracking.
The IR camera sensor is used to track up to four points of IR light.
no its like a smartboard which you can "write" on the screen. http://johnnylee.net/projects/wii/

I see it is not a wilmote, but a Wiimote, a remote for a Wii game.
