As a pilot with an amateur radio license (though an inexperienced ham) this sounds really interesting. Could you elaborate more on building the VOR receiver?
The transmitter has an electronically switched antenna that virtually moves in a circle at 3600 rpm, causing FM modulation phased with direction. The carrier is also AM modulated with a reference phase signal.
I built a gnu radio flowgraph to receive both and display heading to the VOR.
Not ATC but recently obtained my pilots license at the ripe old age of 41 and trained at the busiest class delta in the US. 30 year old age limit seems pretty restrictive .
Are you a pilot or ATC? They’re different, but you build a visual representation of traffic in your brain in both arenas. As a pilot you cannot rely on ATC- you have to fly the plane first and keep yourself safe.
Not the GP but I've been a pilot for about 6 years and have friends who are controllers, and being a controller is entirely different, and pretty difficult.
You can fly VFR without services and you really only have to worry about yourself. There's no equivalent as an ATC. You're often working multiple frequencies on your own. Even if you don't typically do it on your own, if your coworkers gets sick now you are. I've had friends manage two tower frequencies as well as ground due to staffing issues.
Not to mention the fact that when you become a controller it's much like the military where you get assigned a place and you go there. You get preferences of course, but there's only so many suburban airport controllers needed - somebody needs to be in JFK tower and somebody needs to be in the middle of nowhere Montana and they're not flying in for their shift the way pilots can.
I'm inclined to trust the FAA's data that it's just not feasible to dump training resources into someone who statistically is either not going to make it or is going to quit if they don't get their preferred assignment and find out they need to move their family to Utah.
I assure you the mental picture you need to keep in your head as a controller is far more taxing than single pilot operation when you are primarily concerned with your own separation. A controller can be managing a 1 to 2 dozen aircraft, dealing with pop up IFR, flight following, traffic advisories, handoffs, etc. There's a reason you get a mandatory break after 2 hours.
It's not about the mental task. It's about selecting for a demgoraphic group that's more compliant and less likely to take risks. They want to lessen their chances of having egg on their face because they hired some young cowboy who, when faced with some impossible set of bureaucratic constraints decided he'd shirk whichever one of the conflicting restraints they didn't like rather than just take the KPI hit.
The under 30 crowd has a lot more of those types than the over 30 crowd.
I do not believe this is true in any meaningful sense. Schindler's list, Operation Valkyrie and the like are firmly embedded in popular culture. And of course the claim that all of any nation share an ideology is absurd to anyone who thinks about it for two seconds, but I'll give you a pass on that because I don't believe you're talking about people who think for two seconds (I claim that that is also an important error in your worldview, but that's tangential).
Not here (different EU countries); we are taught in school about both sides. There are many books based on reports or letters by soldiers or concentration camp inmates describing Germans not believing in the war effort and more so not believing in the holocaust and helping people. Schindler is a famous example.

Piggy-backing this comment to add some context for the OP video: This "USB device discovery" video is actually the latest in a series of videos where Ben Eater is building a simple 8-bit computer on breadboards. He hooked up a PS/2 keyboard as an input device, and then got sucked into a tangent of investigating and explaining keyboard protocols.
- Somebody on Patreon asked about USB keyboards having higher latency than PS/2, so he made a video about the basic USB protocol: https://www.youtube.com/watch?v=wdgULBpRoXk
- He made the OP video about USB keyboards being limited to holding six keys at once.
