Two Toyotas. The steering you apply, even with almost no torque, always overrides lane keeping. Super dangerous. No beeps when that happens. Whereas with my Tesla you’d have to force it out of autopilot. Or fight a bit back if the car corrects you for safety.
The regulations are great, in theory. In practice, I've noticed that implementation of the technologies are lacking. So on paper, lane keeping will keep you on the road when distracted. In practice, it does not. You'll be beeped at a million times, though.
I dislike ‘energy religion’. Nuclear is necessary for Europe. We simply can’t heat our homes and power our industry with renewables in winter. At the same time wind and pv can be built up faster and is simply cheap. Hydro where topography and local bio conditions allow it. We need all those technologies, so we can move away from fossil (climate, resilience and depletion).
Set it up myself, mostly. Some specific tasks like bringing three-phase power to the garage and hooking up the breaker box I did with an electrician. But installing an additional circuit inside the breaker box, or putting new conduit up, is easy to do safely yourself. Pre-wired breaker boxes can be configured online and are cheap.
The battery is 16kWh. Effectively around 14kWh, since you never fully discharge. LiFePo4, so no chance of spontaneous combustion like other battery chemistries.
I'd say the months Nov→Feb are tricky, although since I have quite a bit of excess solar capacity there are even in December plenty of days where the battery pulls me through the night.
Charging/discharging from/to the grid is possible, since I have a retrofit inverter (AC to battery), but not doing it yet, have to do a bit more research (dynamic pricing, tax is >50% of the kWh price in NL, etc).
Every installed PV-panel is a dozen barrels of oil (eq.) less CO2 in the atmosphere. Plus, so much fun to generate your own power! Can highly recommend it, even starting small.
It's addictive though. Living in the center of the city (The Hague, NL), with a home battery, I'm now 100% self-sufficient electrically for 10 months of the year.
Same! Set up a DIY home battery system and needed something to communicate with the inverter and battery over RS232, RS485 and bluetooth. Had an old Raspberry Pi-B with 512MB RAM lying around.
Running 3 python scripts as daemons would become a tad heavy and was a bit worried about serial timing. So used Codex to rewrite them in Go. Cross-compiled them, deployed the binaries and they're now running very comfortably on the pi. A few MB of ram per daemon. Making good use of an almost 15 year old device.
> especially not to spec torque on terminal connections and botched crimps leading to hot spots
This was indeed my greatest concern. However the battery came with pre-crimped very solid DC wires, and nice push connectors for the battery itself. The battery also has an integrated DC breaker (great!).
The system runs 3KW max, so I just added an additional breaker (with RCD integrated) in the conduit box. In NL this is something a DIY-home owner easily can do themselves :) (just use the right solid/flex stranded cabling for the connectors, etc...)
I will do a write-up in a couple of days. It's all relatively simple, you just have to expect terrible documentation and do a bit of reverse engineering and serial sniffing. I expected the battery to be complicated, but it turned out that the inverter was.
You'll encounter stuff like: manual says use RS485 port on Battery for GroWatt inverter → need to use CAN port on Battery. Meter Port (RS485 [serial] over RJ45) wiring on GroWatt is unknown (A: white orange / B: white blue, cross them over). Dinky RS485 serial → USB converter needs a 120ohm resistor between pins for line termination. Growatt meter port expects a SDM630 meter, not a DTSU666 (hardcoded), so vibe code another emulator. DIP switches for RS232 connection need to be both on the ON position (undocumented). CH340 USB→serial converter for RS232 does not work, but one with a Prolific chip does. Etc. etc. etc :)
Oh, and the biggest one... I was expecting to be able to just send a command, 'charge at 500watts', now... 'discharge at 2000watts'. But no. You have to emulate a power meter and the inverter will try to bring the net power to 0. Fun! :)
Battery prices are getting really low, if you're willing to do some DIY. Just received a 15kWh battery from China. A 'Humsienk'. Combined it with a GroWatt SPA3000TL-BL inverter.
Total price, 1600 euros. So close to the magical 100 euros per kWh. Driving it with some interesting combinations of Raspberry PI's and serial interfaces and custom written Go code, but it works... :)
> iPhones can still come with Safari installed and used by default, no changes to anyones experience at all.
No, this is not allowed and currently also not the case. When you're setting up a new iPhone, one of the questions during setup is which browser do you want to use.
No, of course, everyone should be free to have the choice to install whichever software they want on devices that they own. E.g. put the phone in developer/hobbyist mode by connecting it with a USB cable to a PC, show some big fat warnings, and then allow all forms of sideloading. But it needs to be like a safety switch.
Then the matter of an informed browser choice. This is simply not a thing most regular people make or care about. Remember the Internet Explorer era? In this case, simply the most recognisable picture gets chosen (e.g. the only company that advertised their browser).
As a EU-citizen, I'm not happy with this legislation and enforcement. I choose Apple versus Android, because I want the safe and user friendly ecosystem Apple offers. Otherwise, it makes much more sense to go with Android. Those phones are much cheaper and are very much the same quality-wise (performance, screen, form factor...).
The same goes with iOS on iPad. I'm very happy that my parents can use those devices versus a Windows machine (or even a MacBook) and know that they are pretty much safe from malware.
Even now, I noticed that with the mandatory browser selection screen both my parents independently have moved on from built-in Safari to Chrome (independently), since that was the only browser name they know. And now they are in a much worse position privacy-wise than before. Which is certainly not in the spirit of the GDPR and DMA.
Agreed. In my case with a 15" MBP M1 Max and two LG UltraFine 5K's, which I always plug in the same ports, 99% of the time it remembers which display is which correctly. On my 2018 Intel, this was hit and miss. It's obviously not a trivial problem to solve...
This is indeed the main problem. If you have two screens of the same model, the OS is unable to see which is which. This also goes for many USB devices (such as webcams that randomly swap).
Nice article. Wondering though why trading is not done in discrete batches, e.g. 5 second intervals? Trades in the same interval get filled equally or stochastically? Info about trades with that same 5 second batch delay? Is there some (theoretical) market efficiency thing at play? All this HFT feels wasteful and bad for 'regular' human investors.
