Indeed. The hardest part these days is getting access to a garage.

On that thread, his garage is larger than the entire space I rented for living in when I was his age. But the point I'm going on to make isn't just about how stupid the cost of housing is; it's that the high cost of housing comes with extra costs that we might not even see. How many people would be doing all sorts of neat things, some of which would genuinely bloom into real advances and ideas and genuine new wealth…

Back in the early 1970's at the university I used to hang out in the rapidly developing IC fab shop with a fellow student who was an EE major. It was a unique time when individual innovation was at its highest point, and crushing financial pressure nationwide was only beginning to force the downward trend since then.

This was pretty interesting to me as a chemist, and there were even more parallels once I went to work for a company specializing in emerging chemicals, where unending experimentation and innovation was essential to bring yields up to tolerable levels from starting points which were barely feasible. Similar to emerging semiconductor processes.

With all the effort Zeloof has put in, apparently single-handedly for the most part, in his garage he does have what looks like a more advanced facility now than they had then. With the ability to make repairs and do maintenance on the comercially available equipment of the time, to a degree and with determination that the leading professors did not even usually possess.

This is the kind of person that needs to be protected from potential disasters that could derail his continuous progress, especially with such an early head-start.

Very much of an outlier, but there are uncountable others who have always had to wait for the least bit of opportunity which never arose in any realistic way.

Makerspaces are a godsend. I have 24/7 access to one for only $75/mo.

Not only do I host my own machinery there, but I have access to others’ and communal appliances and training on how to use them (as long as schedules line up).

If my parents had bought me a $30k laser cutter I would be too. But I can't even afford the garage. If you want to worship a DIY-god then look up Jerry Ellsworth. She's the real deal, unlike this guy, and makes chips with her own dumpster-dived repaired machinery, not with contacts to the local University's million dollar research lab.

I suspect that if you had access to a $30k laser cutter you'd be saying you could be awesome too, if you only had a $250k metal printer.

As someone with 0 idea about semiconductors development: How does making your own chip compare to using FPGAs when you need low quantities? What things can you do with your own IC that you cannot do with FPGAs?

It's more of a principle achievement, like, "hey Intel, come cause a shooting spree at my local grocery store while I'm there, because, anybody who did similar DIY things in the automobile-hydrogen space met a similar fate from that industry!" [1]

I can't... you might be able to afford $10k, but right now, I had to think hard before spending $3 last night. I hope to learn enough Verilog/VHDL/RTL to take advantage of the Free Shuttle program they have[1] eventually. Currently, I'm wondering how to go from expressions to code I can load into a bitgrid. The thought of parsing code, building an AST, converting that to an acyclic directed graph of binary expression…

You might try starting here then. It’s a good community as well https://www.tinytapeout.com/ You’re not required to buy the tile to take the lessons

That looks awesome... thanks!

Remote work for the win. The older I get, the less I care about having a large variety of places to eat and places to go (i.e. city living) and the more I wish for some basic space to do the things I want to do. Be it a shop/shed/or generous garage (without a car in it I'm fine with my car suffering from California sunshine).

If you are wondering what Sam Zeloof is up to these days: he founded Atomic Semi [1] with Jim Keller (yes, _that_ Jim Keller). [1] https://atomicsemi.com/

Quite hard to grasp what they are really trying to achieve there. They are building what kind of tools, and for whom?

They're being very cagy, but it's quite likely they're working on "fast" maskless technology. Basically going from FPGA to chip in low enough volumes that maskless makes sense. It'd be a small, but lucrative, niche if they can get a good system at a decent node size.

some people live a very industrial lifestyle, in a studio garage, with a couch and kitchen in the corner.

The main issue I have with all that is that one could have had/home-built most of that in the 80s already (except for the resins). So in a way this all is more about online orders as well as global access and visibility than about the actual tech. Wasted decades in a way. Guess we needed to build the interwebs first.

What would you have used in the 80s to make molds?

I still see that part as the most complicated and work-intensive in a small/home setting. I've been looking at ways, effort and prices for several years now and I'm still split between resin plus injection or just resin prints. And I am still end up with outsourcing as the result. But I'd really like to own that process... frustrating.

If anyone has a really feasible/well working solution for enclosures etc. please post them :)

That said, while I excluded the molding part explicitly, since I thought about CNC milling, pick /place and other computer-cobtrolled multi-axis applications, I think one could have used CNC and/or some kind of "sand" baking (negative) appoach. Not sure what kind of hard wood solutions might also have worked as some kind of medium for subtractive designing the negative for a small production run.

Still not something I would see as easily implementable. But I also have no lazy solution with nice results today. E.g. for implementing display windows some kind of professionally color-coated clear case seems the way to go to get to something that ressembles current standards (always the main problem, anyway). Hard to do that with limited space and without a professional absorber solution.

For anyone else interested in him, Sam has a Youtube channel, but hasn't posted in awhile. He started this stuff as a teenager with a garage that I think many of us would envy now, let alone as a teenager. I've seen him on HN once or twice too. There's a whole world of these home built processors channels and they're pretty impressive. I know some others are posted in other threads, but this isn't my niche so I'll leave it to them.
