An "open material license" costs $2-4k. Basically the same price as Micronics printer. It's unfortunate we won't have a hobby level SLS printer in the near future.

Thanks for the trip down memory lane! So many classics from my childhood.

That's a fair point - if you are going to drive long distances, then a Tesla is the best option in terms of network reliability and price. But for most, an adapter with the occasional road trip isn't a deal breaker. Tesla owners have had to use an adapter for charging at non-superchargers since inception.

If you qualify for this, or know someone that would - kicad is a great tool to learn, and probably the defacto standard for designing pcb's now that EAGLE has been discontinued.

But, I want to give a shoutout to easyeda.com. You can export straight to jlcpcb and it has parts integration with their preferred supplier lcsc.com so that you can do turnkey assembled boards from jlcpcb. It gets really interesting once you start designing with smaller surface mount components that might be too hard to solder at home.

This is so true. My iteration time for printed parts has gone down from 4 hours to 1 hour with the faster speeds. At first, I couldn’t iterate fast enough to keep up. I can pump out a few revisions in a day or play with several concepts in little time. It’s a great time to be get into 3d printing.

Jlc’s preferred (?) circuit making program is EastEDA.com and it has pretty tight integration to parts on lcsc.com. You can of course use any circuit program like kicad. Jlc will assemble boards inexpensively for you if you select the right components (which easyeda will show you if a component can be picked from jlc). I transitioned away from through hole parts to surface mount parts with these tools. pretty awesome that they offer this service for a home hobbyist. They now offer double sided assembly, too.

Or, you can order the components from lcsc and they’ll give you a shipping discount. It’s pretty affordable overall, although prices have increased in the past year.

Close! Booby trap is the one you’re thinking of. Galaxy’s child is where he meets the real engineer from booby trap and Geordi is sad/surprised that she’s nothing like the hologram.

In America, good luck. We can’t even get people to enter/exit a train orderly. It’s not an entirely fair comparison though. For example - trains in Japan stop at designated places so the doors line up with the paint markings. There aren’t any on Caltrain/Bart/nyc - so no one knows where to stand. And the conductors don’t have a consistent target.

Or take a busy underground subway. Japan knows to stand on one side and make way for walkers on the other. That isn’t happening in most of America.

But, I just went to Disney world, and that’s about as orderly/idyllic as I think we can get. When all the people there have a similar goal, and Disney has thought up all the processes to remove friction - like trash cans every X feet make it a beautiful place. Their crowd control is also top notch.

A similar thing happened to me where a contractor bait and switched me. Put down a 50% deposit and he said it was non refundable. I wrote it off thinking I’d never get it back. I got extremely lucky though in that a detective in a nearby city emailed me and said this contractor had ripped off a lot of people and he was investigating. A few weeks later, they refunded my deposit.

It seems like once the police got involved, they were willing to play ball. Somehow, you’ve got to find the contractor and get the police on your side. You’ve got his business addresses and even insurances, maybe the insurance company is your way in?

Good luck.

Tesla after-care is amazingly bad. Falling through the cracks will leave you up a river without a paddle.

You have to be an astute Tesla purchaser to avoid all the “easy” pitfalls. Which simply summarizes to: Don't buy anything that has a weird option. Don't expect to be retro-fitted for anything, and get whatever it is in writing.

With my Model 3, I bought one used from Tesla and it originally came with premium connectivity forever. However, when I purchased mine, it was supposed to only be active for a year (this was the standard deal for used car purchases from Tesla at the time). I still have it 2 years later. They probably have a filter/cutoff by vin # that says who gets premium forever and doesn't filter for sold/resold by Tesla..until they fix that glitch. It’ll happen one day, I’m sure.

The latest pitfall is service. If you have a problem, the only way to talk to someone is to go to the service center. If you have a problem afterwards, you’ll end up as a ticket in the system and no one will get back to you in a timely manner.

Service story time; I had my car serviced for a bad LTE board. It took them several days to diagnose this. When I picked up the car, they had taken apart the panels in the trunk. My mobile connector was in the trunk, and they forgot to put it back in when re-assembling the car. I didn't realize this till the day after I picked up the car. I called as soon as I found this out and could not get a live person at the service center. The call center could only put a ticket in and they'd get back to me in 72 hours. In cases like this, time is of the essence, the more time that's passed, the more likely that my mobile connector would go missing. Anyway, after a lot of calling, no one could get me in touch with someone at the service center. no one. I couldn't drive back down there myself for 5 days. When I finally got there, the service advisor didn't even go ask the tech who worked on my car where the connector was. He just gave me a new one. Very frustrating.

Just throwing in my experience here. Come down to Southern California. The rolling stop is everywhere. Not so much in SF Bay Area where I grew up. People get irritated if you drive the speed limit and make full stops. Especially at 4 way stop signs, I often feel like people are confused by a full stop, lol.

I am also an FSD beta user, and I have my car set to standard assertiveness and it does not roll through stops.

And, one last comment on the vision of the car - it’s a whole different beast with the new fsd beta code. The highway autopilot code is not safe on the streets and until you see the fsd beta code at work, it’s easy to think that it will perform poorly on local roads. Yes, it can do stupid things and cause anaccident, but not in the way the autopilot code will. It’s different.

Search Tesla vampire drain, it’s a thing.

The calculation is muddied even more because the tesla odometer doesn’t monitor two important things: vampire drain, and charging inefficiencies. The odometer only tracks power while your butt is in the seat (so if you park the car and use the ac, it will track that). This makes long term cost tracking hard: you can only depend on the miles driven metric from the car. You’ll need a separate meter to track total energy used to account for inefficiencies (power lost to heat and conversion) and vampire drain.

The car shows kWH used since last charge, and it almost never matched what my smart meter measures if the car has sat for days.
