The "Lassiter" laser LIDAR Ranging Gadget (Wiimote/Propeller)

Introducing the "Lassiter" , an inexpensive laser LIDAR Ranging Gadget (Wiimote/Propeller based)
I have been troubled for a while Re:- Laser experiment It required a Bluetoth connection to a pc for it to work.....
..... now i have removed this "MiddleMan", all can be done with a simple parallax propeller system ....YaY
What you see here is my first successful setup :-
- Propeller easyProp board
- Hacked Wiimote camera mounted on servo
- 6 holes along the white Depron you can see a Laser
- Behind you see the lassiters composite video screen
The laser faces forward, hits the object and bounces back to the Wii Camera.
When and object is placed in front of the laser the reflected laser light hits the Wiimote, the closer the object the more to the right the dot on the display goes.
Why does this happen :- in a nut shell the laser and Wii-camera are set at an angle to converge with each other.
Even in this mode its possible to measure distance (so far 2meters max) - plan it to use it as navigation aid.
I was bogged down with converting a number to a string (as my memory was almost used up) so CTC poked me in this direction :- "Numbers.obj" This won the day for me and i could display variables to screen.
The accuracy appears to be 0.5 mm steps ...... uncalibrated ......
The "FireFly" - "Trash" episode inspired me to call it the "Lassiter" .............whether i go for the whole look is still a mystery to me.
(however if you want one then order now not to be disappointed)
Makes me wonder just exactly what the handle is made from.
Still long way to go ..... the videos show the InfraRed proof of concept part of project - and how i hacked the Wii-Mote
