Projector mod's:
I made these after reading about this cool project from rog8811 shown here: http://laserpointerforums.com/f42/hand-held-projector-26445.html
I thought I would share some pictures. For the project box that I found, the hardest thing for me, was aligning the motors and mirrors so that the end result would project the image out of a relatively small hole at the other side. I had to try to keep it this way because I had no ceiling space in the box. (batteries had to go there)
I had to mount the motors as low as possible because of the fact that the only place for the batteries to be mounted was in the lid... So, I used the circuit board, (because it is thin) and soldered the motor mounts (clips) onto the board and then glued the board to the bottom of the box using some strong CA glue.
I mounted the switch at the back and a 100 ohm pot at the left side. I also found that by putting a 10 ohm resistor before the other (fixed current) motor, I had more control/range with the potentiometer driven motor, because I could adjust that motor both faster or slower than the motor with the fixed speed.
This project was to me, kind of difficult because of how tight the fit was. It is also very rewarding. Thanks Rog for this great project! It has been one of my favorites so far!
I have a glass lens over the opening now...
Hey another discovery! The laser mounting method which I found, just happens to be perfect for the Sentorch as well! If any are interested, it is just an electrical connector for the flex pipe stuff. I got it at Home Depot. It says 'Arlington - 1/2" '.
The white plastic 'inner' part is a perfect fit for the Deal Extreme Greenies...no modification needed. Nice tight fit. Just unscrew the fitting and remove the two inner pieces and the Sentorch fits nicely. (I had to do just a very little sanding/scraping on the ID of the outer ring to get the right fit for the Sentorch. (The box mounted part of the fitting, is slightly tapered on the ID, and just so happens to be the perfect fit for the OD of the Sentorch! So, that when you slide it in place, it fits snug and stays aligned)
Anyway, it's a simple thing to change over! Thought I would share this cool discovery...
Another one... I finished a different one usint 3 X AAA batteries!
I added a glass lens to protect the inside from dust.
Thanks for the cool project Rog!![Smile :) :)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
