How do you find this obscure stuff?
TechMoan (admittedly a very odd name, I think he explained once long ago how he came up with it. Something about having the domain name, so why not use it...) is a popular YouTube channel covering all sorts of "nostalgic" technologies.
That British dude spends a fortune finding strange and interesting old tech examples of consumer electronics in working condition (or he repairs them) to film their operation (I'm old. I said "film"... see?) and put the videos online from the stuff he buys for his personal collection.
He also oddly has a huge playlist of reviews he's done of dashcams.
So either the "Vintage Audio and Hi-Fi" group had a link to him, or he came up while I was looking for dash cam reviews. Not sure at this point. I've been watching his stuff for quite a while now.
He also does the occasional review of something modern, and somewhere along the line he decided to show off his puppetry and awful sense of humor, which he does as bonus material at the end of some of his videos.
The Vintage Hi-Fi stuff he has is impressive. At first I would watch some of his videos on old stuff like his working first edition Walkman cassette player and collection of MiniDisc and LP players and such, but he finds much crazier stuff that completely failed in the marketplace. Stuff I've never even heard of, even though they were sold in my lifetime.
He's got about half a million subscribers now on YT, and I think he's figured out that the reviews of modern stuff aren't what keeps people subscribed, it's the weird stuff he collects that most are interested in.
Being a nerd with a penchant for test bench electronics work, I really liked his episode on "oscilloscope music".
