Step 1: Glue the two acrylic circles

Put both discs together, glue them and leave about a 1 mm gap between. I used a piece of plastic.
Leave a gap to take in liquid.

I have tried a lot, it was best with paraffin and colored water.
Best 3/4 oil and 1/4 colored water.

- Close the opening with a soldering iron.

Now turn the LED on and put the lens of the slide projector and calibrate the objektiv, that you get a good picture on the wall.
You can also use only one lens but I've simply taken the two originals.

Next step: mounting the components on a fixed plate. (e.g. on a laminate plate)

I have welded a screw on the middle of the disc, to mount it on the engine.

I have only choose a 8V transformer for the LED, it is not so bright like 12V but that way you don't need a fan to cool.

Step 6: Case

I wanted to make it without a fan but I safely install a fan, because some heat formed by the engine and the led.
