Finally, my bits and pieces from China have arrived! Recently, I have been doing all of my shopping on eBay, buying things from China. If you can stand the wait, then it pays off because it’s so much cheaper!
My next task is to try and assemble my bag o’ parts into a standalone pair of specs. Because I don’t have the knowledge and experience to create a face-tracking application, I have to use 4 IR LEDs on a pair of glasses whilst being ‘watched’ by a Wiimote. I have:
- 4x 3mm 940nM IR LEDs
- 1x 3mm red LED (as a power indicator)
- 1x SPDT PCB-mounted switch
- 1x 23AE battery and battery holder
- 1 pair of stylish black and orange glasses with non-indexed lenses
The positioning of the 4 IR LEDs is very important as they must be equidistant and must all lie along a single plane in order to allow me to triangulate the distance accurately.
As you can see from the photo, I have already attached the battery and battery holder to the glasses using cable ties. The next job is to mark out the positioning of the IR LEDs and the switch and solder the whole shabang together with a resistor in the mix to keep things dissipated correctly. Thanks to http://led.linear1.org/led.wiz, I am able to work out that I need a single 220Ω resistor.
In other news, I have now mixed my Wiimote patch and my 3D cube patch to create a cube that revolves with motion input from the Wiimote (apologies for the poor quality!):
So I am now well on my way to creating a usable, workable system…
