An interactive whiteboard for under £50 using a Wiimote Part 4

In the previous entries to my blog I have explained the following

1. The Wiimote interactive project

2. The paring of the Wiimote to the Bluetooth on my PC

3. How to make the Infra red pen

In this final installment I have made a short video to demonstrate how to set up the interactive whiteboard with a laptop and an LCD projector

Apologies for the poor video quality. I used Camtasia Studio to create the video and then produced it as a Windows Media file. I also produced a Quicktime file which was better quality, but the file size was 2.5 times larger, so I have stayed with the wmv file

Please feel free to contact me if you are keen to have a go yourself

Many thanks to Johnny Chung Lee for creating the software that lets you use the Wiimote like this

In the Wiimote part 2 I explained how I had got the Wiimote to pair up with the Bluetooth on the PC to the extent that I could run the interactive whiteboard software.

Last weekend I made an Infra Red Pen.

Here is a video to explain how to do it yourself.

Apologies for the poor quality of the still pictures, I will make an improved one later on

Knowledge is for sharing

An interactive whiteboard for under £50 using a Wiimote

The Wiimote is quite interesting in that it has an infrared sensor that is more than just a receiver like those on your TV. I have not looked too much into the detail but I have not seen anything like this before

Nintendo augmented the remote with an infrared image sensor on the front designed to locate two IR beacons within the controller's field of view.

These two sources of IR light are tracked by a sensor in the front of the Wiimote housing. By tracking the locations of these two points in the sensors 2D field of view, the system can derive more accurate pointing information.

More information can be found here

We thought we would have a go at making an interactive whiteboard ourselves.

If you're interested here are the steps to hopefully bring success:

1. The video showing how it works

2. How to make an IR pen

3. List of working bluetooth adaptors

4. List of parts from Farnell (Could not find what I wanted at Maplin)

5. A Wiimote from Argos

I'll blog about how we get on in time

If anyone in the UK has made one I'd be interested to know how you got on
