I successfully modified an M550SV today. All you have to do is remove the control panel and solder a jumper between either diagonals of SW1.
Edit 10/07/2013: This does NOT work… after about 20 seconds the monitor will shut off again. I found this out yesterday and am supposed to be installing 6 of these in the simulator tomorrow where I will no longer have access to this panel.
Edit 05/31/2014: I realized that I hadn’t updated what I ended up doing… I did a home-run of two conductors from each monitor to a relay which does a momentary (1 second) switch simulation. I was able to use just one relay with all of the positives from all of the monitors on one terminal and all the negatives of the terminals on the other.
Edit 06/30/2014: It looks like I did this for nothing – the monitors seem to power on when they detect the VGA signal from the computer… DOH
Edit 07/31/2014: Okay, I didn’t do this for nothing… apparently if the monitors shut off because they lost the VGA signal, they will come on when they detect the VGA signal. But if you lose power to the monitors they will NOT come back on without hitting the power button.
Officially an LLC today, filed just under the wire for 2012. A firm that insures operators of amusement attractions recommended that the manufacturer (Unistellar Industries, LLC) be separated from the operator (Paragalactic Entertainment or a variation thereof) for purposes of legal liability and, ultimately, the ability to obtain insurance.

The order arrived damaged. I took a picture of the end that the package was resting on – it had all but separated and you can see the acrylic edges. The two smaller 20.625 x 36.625 pieces are fine but the 26.750 x 47.625 pieces both have one affected corner. The largest piece 53.625 x 47.625 has two corners on the same side that were affected.

Looking for business insurance I ran across an article with things you can do to lower your premium.
Setting up the maintenance in CMMS I realized we did not yet have a fire suppression plan for the enclosure.
My research led me to Halon 1211.
- Halon is an effective agent on Class B and C fires, the ones you’re most likely to see in a simulator.
- As a gas, it’s capable of getting into hard-to-reach places like the inner workings of your instrument panel.
- It’s a non-corrosive clean agent, which means it won’t damage items it comes into contact with.
- It won’t shock-cool your avionics.
- It’s lighter and more efficient than CO2.
- Halons are low-toxicity, chemically stable compounds.
- It works in gas form, so it will not obscure your vision like the powder emitted from dry chemical extinguishers. Basically, it’s invisible.
The manufacturer recommends 1 pound of Halon 1211 per 140 cu. ft. of space. I found 1.25 pound units (too small) and 2.5 pound units for about the same price.
I also inquired about using automatic discharge 165°F units about the efficacy and availability.
I had a bunch of these left over from military panels that I have been hoarding for over a decade. However, most of them don’t have lamps in them.
Looking at the datasheet I was able to find the replacement 12 AC/DC/50 mA part number is 10-1109.1279 (01-913.12). However, you can’t find that part number anywhere except in reference to the switch datasheet.
I worked with DigiKey technical support this morning and we think the SM1250S will do the trick. I ordered 100 of them and they had them in stock. I will post a follow-up comment and find out whether they actually fit or not. I previously bought the SM1250G but they were too big!
Over the next couple weeks I am going to be installing all of the monitors so that we can start applying the interior skin and also start playing with multiple frustum rendering. Once they are in place I will take precise measurements of each of the corners of the monitors so that we can compute the frustums from some arbitrary point between the two airmen.
Protect the monitors from scratches, easier cleaning, glare inside cockpit is more realistic, and helps another pressure distribution layer in case someone bumps a screen.
Product chosen is Optix® Acrylic Sheet from Professional Plastics.
Optix® acrylic sheet is crystal clear, durable, weather-resistant and lightweight. It also offers the advantages of high molecular weight for ease of fabrication, low heat loss for economy and an attractive clear edge color.
For the 55″ monitors we need 4 sheets at 26.875 x 47.75 (26.75 x 47.625 +/- 0.125)
One of which I already cut from an old projection screen TV that was dismantled.
And another of which is 53.75 x 47.75 (53.625 x 47.625 +/- 0.125) which I will try to thermal form for the top middle.
For the 42″ monitors we need 2 sheets at 20.75 x 36.75 (20.625 x 36.625 +/- 0.125)
