Hi,

I have a very simple working design for a 3d mouse. Does
anyone want it?

Of course! Please post a link to your project!

Hehe - 3D mouse, i am hopefully going to Reading Uni next september and they have this 3D cave where u use a 3d mouse to move and adjust images and objects being represented in the room. For instance a brain scan was used to created a 3d representation of the brain, it would allow doctors to explore a 'real' object rather than just studying a load of images....

I did not use the 3d mouse, but it looked to be very difficult to do, even with someone who was used to using it!

Hi,

Sorry to be dragging my feet on this. I plan on posting all the code and
hw prototype design soon. I haven't made it pretty yet.

I currently have the 3d mouse controlling a lara croft image in 3d.
It makes her move up and down, left right, back and forth. I didn't add buttons to the mouse yet to make her shoot,
but that is easy to do. I've tried it on a Perspecta 3d Volumetric display
by Actuality-Systems. Cool stuff. There is a need for 3d. Anyway, it is
coming:) Working prototype is done. It is just a matter of me posting it!

Thanks,
Dave

Hi,

I've been draggin my feet getting this to the public, so here goes the basics

What hardware you will need:
1. PG4D with PIC16F88
2. Power supply
3. 2 ADXL Breakout Boards My model used the old 203, but any chip will
suffice
4. Wires
5. Soldering iron

Pictures are here:

Hardware setup:
1. Mount the ADXL boards to the PG4D perpendicular to each other
A. Be sure not to mix up the ADXL pad labels!
2. Connect pin 5 (Vss or - or ground) to ground pads of the accelerometers
3. Connect pin 14 (Vdd or +) to Vdd pads of the acceleromters
4. Connect the X and Y pins of the two acceleromters to the
RA0-1 and RB6-7

Software setup for hardware:
I used CC5X. Here is the code that samples the accelerometers and then
sends the value back via serial. Here's the code:

Demo:
I have a working perl to socket to opengl test. I will post this as
well if anyone is interested. Thank you for looking.

Questions are welcome:)

Sorry I fixed it. I called it 3dmouse.zip and not software when I
uploaded it. I haven't touched in months so I'm not sure of the condition
it is in. But I put it up for others to see. Please give me credit if you
use it:)
