DIY Motorization of Epson 5010

I have a 2.40 CIH screen so I was looking to buy my next projector with a motorized lens but for many reason, I choose the Epson 5010.

So before an after a 2.35 or 2.40 film I had to adjust the zoom and lens shift with the help of a stool. Also the focus is not easy to adjust at a distance of 13 feet.

Si I decided to search on internet to find the material to build a motorized system that I completed last week. The system works well, except that my voltage source is to high at 16 Volts. I measured the speed of a motor at 18 rpm instead of 12 rpm nominal. I have ordered a PWM motor speed controller to lower the speed o all the motors. Update to come...

Next step is to install a motor for the opening and closing of the black panels each side of the screen to change the screen ratio.

Here are some pictures:

Total cost is around 350$.

Here are most of the parts:

You will also need a 12 Volts source with a fusible, 12V connectors, a piano hinge some pieces of wood and screws.

If you are interested I can PM you more photos and an Autocad DWG of the assembly.

I have bought a motor with more torque and higher speed to move the masking each side of the screen. It would be more appropriate for the drapes.

I will PM you a link to more photos, spec, Autocad and PDF drawing, Excel Spreadsheet.

I don't understand why.

The pics are still there and I can see them from my computer and from another computer running windows 7.

Anyone else see the pics ?

For those who cannot view the pics, here is a link:

BTW I have received and installed the PWM motor speed control and it is now working very well.

I will make a video and post it when I return from a short golf vacation next week.

I had the same problem with the hubs and ordered some from UK. The address for one hub is:

Keep me informed of your progress.

I finally made a little video showing the change from 1.78 to 2.40 and back. You can see the mpg file here:

It is very convenient and used every week as 50% of our viewing are films.

Films with a 2.40 ratio are a lot more immersive when the screen diagonal is zoomed from 98 to 125 inches.

falafala have you looked at "Cinema de RobSev" on my signature below. most of your question are answered (sorry its in french). As for the 3010, do the zooming manually and see if you can live with the shifting of the image.
