Interactive white boards can run about $2000.00. You can use the Nintendo Wii Remote to create one for about 85$. One Nintendo remote is about $40.00, software can be free to $25.00, an infra-red pen is $10.00 and the Bluetooth Dongle is $10.00.
I have a Windows 7 64 bit PC without blue tooth capability.
The most difficult part of this project was getting the Nintendo wiimote to connect to the PC.
I ordered a bluetooth dongle from wiiteachers.com. The dongle came with software. DON'T USE THE SOFTWARE THAT COMES WITH THE DONGLE. Only use the bluetooth software included with Microsoft. Do not download this software either -> http://bluetoothinstaller.com/. There is a known bug in this software for the 64 bit software that does not allow you to open the Device and Printers window from the Control Panel after installing it. I had to go back to a previous restore point to get my computer back to a clean point so I could get the wiimote to work correctly.
Put the bluetooth dongle in a USB port and wait for windows to install the device driver. Check to see if the USB "radio" device is in the "Devices and Printers" window.
To connect the wiimote: Click on the START button, then Devices and Printers. Click on "Add a Device" at the top of the screen. Hold down the 1 & 2 buttons near the bluetooth dongle while the system is searching for the device. When the device shows up in the window, click on it and select next from the bottom of the window. Choose the option "No Code" at the bottom of the next screen. Close the window and check the device manager. Your new wiimote should now show up in the "Devices and Printers" window.
I have not been able to make the new Wiimote with MotionPlus Inside connect to the computer correctly. The only wiimote I have been able to connect was the older basic version. Most stores don't carry the older versions of the Wii remote. I would recommend buying a new model and trading a neighborhood kid who has the older version that you need.
After the wiimote is connected the software will walk you through the set up of the whiteboard. You will need a projector to finish the calibration and set-up. I used SmoothBoard 2 for software, mostly because there is not much else out there. The free version on http://johnnylee.net/projects/wii/ only seems to work with 32 bit machines. Or I just haven't been able to figure out how to download and install it, which may be the case.
Here is a good website describing the Windows XP version of setting up the system. http://mkeadle.org/wiiboard/ This also has a good list of parts needed to create your own InfraRed pen if you don't want to buy one.
