Sometime in the past couple months, there was a link on HN to a project also by one dude, who's implementing a CPU on breadboards, with wires. (Can probably be found by the score filter from the ‘undocumented features’ of HN: the post got >2000 points.)

Computers aren't necessarily gigantic corporate undertakings.

I'm not saying it's not possible, there are much stories in HN about guys creating VGA cards or self-made computers, I'm asking for evidence.

Maybe you mean Ben Eater. He has a great Youtube Channel: https://www.youtube.com/channel/UCS0N5baNlQWJCUrhCEo8WlA

I was mistaken, the CPU is a stock Z80 but the guy implements other parts of a bespoke game console, in microcontrollers.

All of that sounds very interesting, but as edgarvm points out, it's not exactly evidence. Reads more like a product brochure than a research paper detailing how their claims are possible.

Also they offer a course in building your own electronics that you can sign up for if you go to their workshop. I can't go to Mexico so I haven't signed up for it; it's at least theoretically possible that the course doesn't really exist and will be canceled if you do sign up for it. But if that doesn't happen you can go there and take the course and see the G11V3 and presumably Fénix and Biyubi in person. I've seen comments in news-website comment threads from people who claim to have done so and claim that it's real, and no comments from people who claim to have done so and then been rejected, so it seems most likely that the course is for real.

Together with Óscar Toledo G.’s amply demonstrated skills at programming under extreme resource constraints, skills which require a great deal of practice to acquire, I think the evidence strongly favors the hypothesis that Fénix, Biyubi, the G11V3, the electronics courses, and the rest of it is real, if maybe a bit oversold.

I could not find any information on a course available, could you point me in the right direction? It is a bit odd to me that none of their products are available for purchase from their website (I saw the $99 computer with minimum order of 1000 units but when clicking through I was redirected back to the home page).

I think their G11V3 computer design is pretty out of date now.
