DIY Motorization of Epson 5010

post #1 of 25
Thread Starter 
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:

Well done!

Wow, now that is cool. I wonder if a company makes something for manual focus rings so you can be next to your screen while focusing instead of at the projector.

Thank you so much. If you have any additional info I'll take it through PM!

One quick question, would these motors be adequate for drapes? Considering buying a 2nd controller to use for masking drapes.

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 ?

The pics are still there for me. Pretty neat, auto zoom, shift and focus on a 5010. Good job.

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.

Thanks for posting this, I'm ordering some of your listed parts now to try on a Marantz VP11. cool.gif

The hubs are back-ordered though, won't be available for about a month, they say. frown.gif

Awesome Idea !

Can this work with Epson 3010 ?

Also do you have some kind of "lens memory" with this setup ?

Could you post some details on your CIH screen ? what is it ? where did you buy and for how much ?

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

http://robgsev.site90.com/Motorisation%20Epson%205010/video/

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.

Thats dedication!

I finished construction of my [zoom only] mechanism for my VP-11, it works perfectly, thanks Bobsev. I can't take photos right now, [The projector's tucked away in a shelving unit].
