This is a really beautiful bit of kit, really like the case and the thought given to signing, but the analog side is really impressive too. Would it be viable to use the same hardware as a base for an NTP server?
Wayne Green [0] is responsible for that. Responsible for some publishing innovation in the electronics world, he started with writing about radioteletypes for hams in the 50s, and moved up to Peterborough after starting 73 magazine
I think an easy win for tram/tramtrain systems would be to have capacity to move cargo, either in rollcages like grocery shops use, or on pallets with dollies from a peripheral location, to city center locations and eliminate at least some light goods vehicles. The problem is, it would probably be a very inefficient use of labour to have humans do all the last few hundred yards pushing.
This reminds me of a pet idea of mine, to write an interactive fiction / text-based dungeon crawler based around trying to navigate underground tunnels and interacting with various weird computers throughout them to progress (take the TTY from the seismometer and use it to access the ventilation control computer, find the datatape of the plans for level IX to then find the hydraulic controls for the main blast door ect.)
There's software to use pens on a 3d printer to draw on paper on the bed, and it wouldn't need to be a very high specification on to turn out acceptable results
I love the lathe project [1], I recall looking at it quite seriously when I was younger. Inspired by this site, I welded up a crucible and setup to cast aluminum using charcoal in the bottom half of an old pot belly stove, with a hand dryer reused as a blower for heat. I did manage to melt some scrap, but I didn't have a mold ready that time. My diy flasks weren't great, and I lost interest while trying to get some green sand. I would like to try again though
Well, you'll be able to tell which ones have been in crashes easily, due to the stainless steel showing dents and scratches. Deloreans which have had accidents nearly always get painted with paint in order to conceal the damage and its correction using filler, so it's a good bet that cybertrucks will show up in many different colours. It'll be interesting to see which colours people choose on the blank slate of stainless steel
Lots of smaller monarchies, which isn't necessarily a bad thing provided there's freedom of movement, so that you can move to the monarchy that fits you best
A Citicar might work well for you, although they're all a bit old now.
Apparently the Tazzari Zero [1] is available in the US, otherwise I'm unsure what else is available, and how electric vehicles interact with the US import rules
Is there any data on how much of private jet usage is for urgent medical requirements, government contracted transport and transporting specialist workers quickly? Maybe this report is taking private to not include that usage, but I can't find it.
I would like to think that the well off would behave in a manner similar to how people in Germany who can't be bothered taking their bottles back for pfand do: They leave them beside the bin where people who want to can collect them and cash them in
Perhaps a used battery purchase scheme would be a good solution? There is some value to the used batteries, if the city paid a premium over that, the problem would most likely decrease significantly. By paying more per kilo for the larger batteries (which pose the greatest risk of injury), city workers would be much safer. The city could even create a market for the recycled Lithium by requiring its use in equipment supplied to the city
If you want some entertainment, look up the Jones Act fleet. I believe the biggest and most modern vessel in it is actually a foreign vessel that the US government seized from criminals and auctioned off.
That was an extremely interesting read, although I must admit I'm glad I never came across it in the wild. I wonder how things could be different if client certificates were more widely embraced? It could be useful to prevent social media account hijackings
Low bandwidth mesh for email ought to be viable, I'm sure that used telecoms equipment could enable a 'good enough' network, although perhaps using QRP APRS equipment would reduce the cost when starting from an energy demands point of view, and better account for the fact that packets will occasionally have to wait a few hours until the batteries in other nodes are charged.
I keep on seeing all this talk about Powershell, and it's inspiring me to maybe learn some, although I've already commenced pursuit of skill in bash and python
