The Roll20 Digital Gaming Projector: Howto Part III

It’s been 21 days since my last update. Since then, the projector has arrived (no thanks to Purolator’s delivery policies), as has the matching remote control that I purchased. With our new baby it took until the afternoon of the 27th for me to find a few hours to assemble a carriage/housing.

Seeing as the ceiling in the gaming room is quite low (6’6″) a traditional projector mount wouldn’t suit my needs. I needed to conceal the wires (as best as I could, hold a power supply, and support a hanging mirror). In the end, I designed  a hollow track system that I could run the wires through, but that would allow me to slide/adjust both the projector and the mirror. Sharing measurements is in my opinion, pointless. I made a few educated guesses about how durable I wanted the design, and selected economical materials from there. I then cut them to the length I needed for my specific setup.

Here is a mock up of the track from an end view:

Most of it is held together with epoxy and finishing nails as I was too impatient to wait for wood glue to properly cure up. All wood/MDF received a coat of “Cream White” spray paint so as to not offend my wife (Cream White was the closest colour to what we had painted the ceiling, and using the word ‘close’ is a stretch).

I did think to take a few pictures as I was mounting the whole affair to the ceiling. I’ll comment on the photos as we walk through them.

The first photo is the track laying on my gaming table. You can see the various cords and cables that it conceals. Four screws (one at each corner) were pre-drilled and prepped for mounting onto the ceiling.

Inside the Track


I skipped ahead slightly without photos as I was doing this on my own, but here you can see that the track is mounted to the ceiling, and I’ve slid the projector onto one end of the track. I elected to plug it in and try it just after this photo, before I got too far and realized the cables were unplugged or damaged.

Ceiling Mount


Here you can see the wire covers that I cut on an angle so they would hug the wall. The room has a ‘barn’ style roof, so each angle is different.

In this picture you can see the mirror that I am using to bounce/reflect the projected image onto the tabletop. Thanks to the handy track system I was able to fine tune the image by adjusting the distance and angles. This will vary greatly for anyone else doing this. My advice: leave yourself lots of room for adjustment.

The Mirror


Finally, we have a test image using and the miniatures of my Pathfinder players.
