Hello,

I am currently trying to get scoring for a little two lane community center going. I would love to get up with you and learn how this works. I was toying with writing it myself with the help of AI but I haven't gotten it off the ground yet. I would like to pick your brain about it. Happy to take it off HackerNews.

Heh - do you have a "blog" (ala jwz's DNA Lounge)? (This is the kind of retiring from IT tale that I love to read and follow the trials and tribulations of over the years - good luck, thanks for open-sourcing your work!)

man I haven't thought of that blog for like 20 years. crazy how many old blogs and web comics that I used to check every day that I've mostly forgotten about.

I only check 4/day now. For awhile when RSS/Atom was big, I had hundreds - but was inundated with "too much info" and so wouldn't check anything for weeks at a time and then it was a slog - never did get into the Google Reader, was a fan of RSSBandit.

My dailies continue to be; Antipope (Charlie Stross), Whatever (John Scalzi), Contrapositive Diary (Jeff Duntemann) and the aforementioned jwz...

Earlier quoted context omitted.

It does. But it's nothing special. This isn't "software engineering applied to a physical system". This is just software (and some hardware) engineering. This is just engineering. Making things to do things. You want to do something and you make a machine that does it.

Fair point. I think what I found interesting was using modern, affordable hardware to replace an expensive proprietary system.

Now you get to sell copies of your system for slightly less than the other proprietary system, thus creating a competitive market.

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…

We had a guy give a talk at our local nerd meet-up about doing this to an old landrover with the hopes of commercialising it. Did a good job, but it was only for someone with money to burn. Looks like he did commercialise it: https://www.jauntmotors.com/series I recognise some of the photos from back then.

I'm a bit slow on looking at this, but looks to me like it is for a full-electric conversion and not to a hybrid?

Still very cool to see and I hope it goes well for him. The more options the better.

I'm CTO at a bowling software company (we also own a few centers), so this hit home — I had a similar reaction when I first started digging in. The equipment side builds genuinely great hardware, but the software has lagged badly. I assume that doing world-class manufacturing and modern software development in the same org is brutally hard. It's a real drag on the industry's growth. Would very much enjoy a conversation if you're up for it — email's in my profile.
