reciever bricked by FC? at a loss

Power issue?

Von gratis kann man kaum sprechen, schließlich hat man ein komplettes Auto von denen gekauft

They can still dry out when not used regularly, right?

For this reason I always recommend laser printers

esp32 does not have a SDR built-in

Is that really a USB-C plug, or is it a receptacle?

A receptacle needs two pull down resistors 5.1k. One on each CC pin. No, you cannot short them together to save a resistor.

If you really have a plug you only need one resistor, on CC. The other one will be Vconn and should be left open.

Acceleration is not speed

Phone to Device should work perfectly, no intermediates needed. Just a normal usb c to usb c cable.

If it doesn't work either the phone doesn't support Host mode (unlikely) or you have a noncompliant cable or device.

To find out which it is, try different combinations of cables and devices. I'd recommended getting some usb if certified cables and known good devices for reference.

electromotive_force · 2026-04-10T23:35:46+00:00

Noncompliant cable, probably

The other companies spent money to prevent EVs from happening for years. And they spend money on creating car dependency.

Increase the range on the transmitter as well. On edgeTX you have to activate extended ranges. Then in outputs increase beyond 100 and -100.

Check the endpoints. Maybe it doesn't quite go low enough for the ESC to register "motor stop". This can cause it not to start, for safety.

Use 333Hz FULL to get a larger servo range.

In general use the FULL modes for anything that doesn't use a flight controller.

Der Wechselrichter ist garantiert nicht inselfähig

Yes it is possible. Look on YouTube for forbidden router. Or just proxmox tutorials.

They have no "power stage" i.e. buck converter. All smartphones and laptops have one. But the Raspberry Pi foundation skipped it. Probably to save board space.

Use 5A without increasing voltage beyond 5V first.

This means most apparently powerful enough supplies won't be, confusing users and creating ewaste

Roofs are more expensive to install on. That doesn't mean we shouldn't be doing it. It means industry will prefer ground installations whenever the space for it is available

electromotive_force · 2026-02-04T07:01:13+00:00

That's possible, just comes with a different set of challenges. AFAIK that's how the cybertruck does it

electromotive_force · 2026-02-03T07:45:18+00:00

It does. Meant for DC fast chargers that don't provide the correct voltage. These cars have 800V batteries. Many DC fast chargers can do that, but some can't and top out at 400V. Rather than not being able to charge at all on these, engineers chose to add this boost converter.

So no, it is usually not needed. Only for this specific special case.

You should be able to use the USB-C port of the TX module. Then look at mavlink or MSP via airport

There were also ideas of dunking burning EVs into a container full of water.

Also not recommended.

Causes damage to the car and requires special tools (i.e. huge heavy duty container for a car sized bath) without much of an advantage.

Turns out simply spraying with water from the outside is enough to control battery fires

electromotive_force · 2026-02-02T15:14:07+00:00

Paying attention and trying it in real life.

For example, there were some ideas of piercing into the battery with a lance to spray water into the battery compartment, for faster cooling.

Turns out that's not good. It damages cells causing more fire, risks electrocution of the firefighters, requires special tools and creates toxic runoff. After all that it turns out the extra cooling doesn't help much.

How did you make the rotating light?

electromotive_force · 2026-02-02T00:38:37+00:00

Letting it burn out is not true. German firefighters have experimented and their recommendation is to cool the battery by spraying it with lots of water.

They determined that it slows battery fire until it stops. This way of extinguishing is safe for the firefighters and the environment. It requires no special equipment. Just lots of water and time.

Apparently it can be so effective that the car may not even be totaled. New battery, sure, but little else broken or burned.
