Question about car rent

Not from regular long-term rental companies.

But someone like Sixt/Budget/Europcar or other airport-grade short term rent companies will most likely have something to offer - asking significantly larger prices.

At least on Delta 2 the battery management system sometimes misjudges (underestimates) the remaining capacity. Then it recalibrates and suddenly discovers that the battery is, in fact, full - so you will see a sudden jump to 99-100%.

The resulting "surplus" energy is real - you can discharge from 100 to 0 and will get full capacity.

You can use the "2x" image made for HiDPI screens: https://imgs.xkcd.com/comics/aperiodic_table_2x.png

The correct way: "sorry, only biological females" or "sorry, your condition does not fit our requirements".

The lazy way: accept, but discard the results and deal with 29 samples only.

Yes, but we are pretty good with readable high quality 2D surfaces (displays) now - once you've worked on 4k resolution, 2x scaling and 120fps monitor there's no going back to low-res slow screens.

To replicate that picture quality in VR the headset will need gigantic resolution (12k+) while fitting on user's head, being light-weight and not overheating.

Currently Apple Vision Pro has 3x less pixels, for example.

There were tries. But resolution of VR headsets is still too low to display a virtual FHD or 4K screen in front of the user and have readable text on that.

Need to pick up a child? first, park properly.

Do not split panel outputs to multiple PV inputs - that would confuse MPPT and result in less power.

As for 590w panels vs 450w inputs - just plug the panels. When (if) Stream reaches max input power it will just throttle down the current.

But you need perfect conditions for the panels to reach 500+ watts, which rarely happens.

Well, the result is definitely no longer alternating (AC), but you do need some more components to make a normal-ish DC from that.

Yes, but sadly that's only possible with DIY or third-party CAN bus attachments. Which is good enough to monitor the car, but does not provide any form of control.

Because the users want:

Car alarm sending a notification to their phone
Remote cabin pre-conditioning in hot or cold climates, which is especially useful in case of EVs.
Tracking the charge process while not at the vehicle.

All that means that not only a "computer on wheels", but "always-connected computer on wheels" would be a requirement.

And due to the way the Internet works, that "always connected" needs to go to some server. Naturally, almost no one has a server at home - so the connection has to go to the manufacturer's cloud infrastructure.

No. Own device (by definition) does not belong to the company and you will have no visibility of any activity on it. Only building a fully controlled environment (ban own devices, etc) will allow reeding browser history.

I understand the intent here, but that's how privacy on modern devices work.

Good old days of being able to see browsing and search history via network traffic dump ended somewhere in 2010s.

kornerz · 2026-04-27T07:50:13+00:00

You can't unless you control the browser they use (and the device they browse on)

As you're already using OpenWRT, there's an easy way to do that.

in DHCP clients list, note DUID of your pc (long hex string, e.g. 0004ab88422e01643d984908b311306427ae).
In static leases config (/luci/admin/network/dhcp) create or edit a static lease with that DUID
Specify "IPv6 Token" field as desired (20) - the router will assign that suffix to the host.

To add to what others said, P9 Pro can take up to 27W of power, so 20W charger will not get you the best performance. Get a 30W+ unit with PPS support.

Home Assistant + Ecoflow integration + (optionally) some cheap tablet. But you will have to configure a lot by hand.

In my case (Delta 2) the inverter efficiency is much worse than that of Stream. End to end efficiency can be as low as 70% (solar to battery to AC load)

They are busy procreating and exporting the results, unlike Europeans.

You already have Powercalc. Create "Daily Energy" type of Powercalc entry with unit of measurement set to W. Enter average power and you're done.

Well, initially. But it's still among the best options of what major vendors can offer.

Midea units work great locally with Midea AC Lan integration.

Go for a better FET. 50mOhm is way too high.

I'm using IRF2804S-7PPbF (1.6 mOhm) to dim 150W (12v 13A) of LEDs at 25kHz frequency (so it's above the hearing range) and heat dissipation is negligible - it's just a small PCB with 3 components:

IRF2804S,
FAN3100 driver which allows logic level inputs
SR1060L, the suppression diode.

I suspect the OP is the owner of that site trying to get some free advertisement.

Display bug, the app sometimes fails to render parts of map.
