Over the years of flying quadcopters and other stuff I have grown quite the collection of self-made or customized gear.
When out flying alone or with a partner, often people walk their dogs nearby or families go on a walk together and see us. This often sparks a conversation. For these occasions, it turned out to be very useful to have some kind of second screen and receiver with me.
A friend of mine even has a spare cheap set of FPV goggles with him most of the time.
I decided to go a slightly different route. For my first experiments, I bought the Quanum DIY FPV Goggle Set. I didn't really like the box-style of goggles, so I quickly took the monitor from the set and used it stand-alone.
After I switched to proper FatShark goggles, I used the Quanum monitor again, this time for a spectator monitor.
I built a simple wooden box out of left-over parts and hot-glue, with a large cut-out in the front for the monitor.
Inside is not only a FR632 Diversity Rx but also an Eachine ProDVR, 2x 18650 cells, voltage regulators, a fan and a voltmeter. The channel can be selected on the receiver, with cut-outs on the back. The DVR can be controlled using external push buttons. A power switch, as well as a switch to select either the Rx video feed or the DVR video feed, are on the top.
The batteries hold up for maybe 3 sessions with spectators. I had to add the fan after the first tests because it simply got too hot inside the box and the first DVR died after a while.
The quality of the Quanum monitor is great and it does not switch to a blue-screen when the signal is fading. The DVR does not work 100% reliable, but considering my FatShark Dominator v3 has a built-in DVR as well, I'm not really dependant on it.
