I see in this one of the competetive advantages of the US at work.

I don't believe any patch of land that size, that you could build on in the UK is available for $105k, or about £78k. Let alone one with a partially functioning business installed

Earlier quoted context omitted.

My guess: 1) New cars are too cheap to make at scale. 2) Old cars are quite unsafe to drive, comparatively (airbags, backup cameras, lane departure alerts, blind angle alerts, etc)

Aerodynamics as well, new cars and especially ev/hybrids are slippery compared to many/the average if we take old cars to mean 50’s through 70’s.

Does that matter much if you only drive around town at 30mph?

This is far cooler than how I've been using my Pi.

I've started building a box for managing agents. I hate sitting in front of my Mac all day flipping between terminals. I wanted something that was audio and whiteboard / paper first.

The Pi has a mic, camera, and projector hooked up. The Pi is always listening, so I just say most commands (i.e. "check logs on backend service, customer xyz said abc is wrong"). I can tell it "look at the board" and it can see things I've written or drawn and can project on top of or alongside anything on the board.

Not sure yet if it's more efficient, but it's definitely more fun.

I think I see some parallels with the aftermarket for old cars. Holley's entire catalog is "here's a thing that'll modernize your 1960s engine without replacing the whole damn engine" This kind of thing is a low-volume, low-margin business by nature. It's those kinds of businesses that the megalomaniacs of our field tend to ignore. There are people with needs, and money they are willing to exchange for a solution to…

There is no shame and no business there. We just read a story of someone who didn’t want to pay market price and went DIY. There are companies doing bowling alley equipment and you can pay them for maintenance. Is there a single one of those on F500 list? No and people are running those companies and what OP did … he didn’t want to pay market price. Well yeah those companies are overpriced if you are software enginee…

Don't dismiss the OP so abruptly. IMHO he is convincingly making the case that there is likely a business opportunity for something between a $120k off-the-shelf system and $1.6k in DIY hardware.

Lol, nice! It depends on what you mean by "owning a bowling center," but it looks like there are at least two of us into this :D I bought a really old fully mechanical (and automated!) mini bowling lane. It works without a CPU, except for the score display, which originally used a 1970 Intel D8749H (MCS-48)! Just like yours, the only thing that turns this machine on is a single relay :D On my model, I also get feedba…

Hah! I remember playing a couple times in one of those Alf Minibowling machines in Madrid in the early/mid nineties... It's a string machine, isn't it?

Kind of funny that factory is in a small town next to Zaragoza...

I love it! I actually looked at integrating with scoremore myself, but once I crossed into hardware world, I still couldn't get over how much fouling alone cost. $750 / unit and they're -ancient-. Definitely will post on bowl-tech as well. I'm just new enough to have a lot of that new-guy anxiety around posting OpenLaneLink there yknow? Those guys know -everything- about this stuff.

Is the fouling functionality more complicated than one would assume? From a naive perspective, it seems like it would just be a simple photo-eye sensor

Yeah. Anyone who hated writing code but had to, like biologists and chemists, now don't have to.

This is arguably a dangerous fallacy, particularly for anything critical. When the person doesn't know programming, it becomes harder to guide agents and do reviews, leading to overlooking issues and accepting mistakes. This gets amplified for any creative solutions or fixing future problems, where it is something the LLM was not trained on or has limited data about the subject. Plus add how much money spent on token…

I think there is negative bias. The counterpoint being that with code you can test input vs output. With foreign language you cannot. Programmed system, either computes what you want or it doesnt. For Spanish you either have a person who can do testing for you. Good practises and cybersec questions matter in programming, but system doing what it is supposed to do (success path) matters more imho.

You can buy land in Northern England or Wales at £10k per acre. Even a large bowling centre wouldn't need more than a few acres.

But you're right in general. Looks like this former bowling centre in Inverness is asking for £1.5m: https://uk.businessesforsale.com/uk/for-sale-leisure-develop...

I once expected an aftermarket industry to pop-up to hybridize old cars. Old rear-wheel drive manual cars sound easiest. Generator attached to the flywheel instead of the starter motor, and then find some way to squeeze a drive motor by the rear diff (probably more complicated, but surely not impossible). I thought something might pop up once companies like Bosch started making generic e-axles for manufacturers to us…

Wouldnt the weight of the old chassis be a impedement to mods , older models tended to be more robustly buildt. Or what cut-off date for mods would be appropriate (last 10 years?) as beyond a certain cutoff would not be cost effective and most likely would be a hobby project done for the love of it.
