The 2nd mirror I made was for my office using a really wide piece of one-way mirror that I had fall into my lap. After a lot of tribulations, I got it done. But I was never really happy with it. The mounting system was clunky, it hung away from the wall a lot, there was a huge dead space in the middle, I used two different processors for the monitors, power was via a concealed power strip mounted on the wall, etc.
I just finished upgrading the double-wide mirror to a triple-monitor setup. New frame, new facing, better mounting and a power plug that I highly recommend to anyone.
First, I build the support frame. I added a rabbit around the inside to hold the glass.
Next I built the facing out of chair rail molding. This is the same material as previous (the boss likes it).
After staining the facing, I joined the support frame to the facing. Eventually, the glass will sandwich between these two pieces. The metal L brackets are screwed in so that I can transport the entire thing as a unit and detach the pieces when it’s time to migrate the glass from the existing mirror to the new frame.
Next, I cut a hole for the power plug. I found these on Amazon. I did have to wait a couple weeks while they shipped from China, but I think they were worth the wait. No more inline switches on power cords!
The power port is wired into a power strip that I also bought off of Amazon. This will provide a place for the monitors and Pi to plug in. It just has enough slots. I’m using every AC and USB socket on this thing. I tried glueing it to the support frame but it didn’t work. I ended up zip tying it in place.
Quick testing to make sure I didn’t miswire anything. You can see some other steps here: the support frame has been painted black so it won’t show through the one way glass. The holes in the support frame for the power cords and USB cords have been drilled and the cords are threaded. The power cords were snipped in order to make it through the holes, so I reconnected those with some wire nuts. There are some pieces of scrap wood on the support frame that are screwed in with one screw. Those hold the monitor up against the glass so the monitor doesn’t slide out due to gravity. They’ll rotate into place one the monitors are in position up against the glass.
After testing, I took it to work and installed in over about 3 hours. I had someone in the office help me which was a lifesaver. It’s heavy! We took down the old mirror, disassembled it, moved the glass over to the new frame, screwed the facing on, flipped it over, removed the monitors from the old mirror, took off the bezels, installed them in the new mirror, took down the old VESA mounts, put up the new French cleats and then finally hung the mirror.
I went back today to configure it. I think it turned out really well!
