The BT stack is based on Bluedroid, so that’s open source (up to the driver I’d guess); see here https://github.com/espressif/esp-idf/tree/master/components/...

That’s really impressive, - although for more deadly weapons deaths/injuries ratio would be different than with drones.

Bombs and artillery is the main weapon, FPV drones are a novelty and they're being limited by being tied to the remote pilot. Pilots don't really scale that well - it takes a long time to train, and they have to be relatively clos

You probably meant DJI Remote 2. DJI RC2 is the one Mavics use. Anyway, I just wanted to warn anyone on the market against either DJI or BetaFPV controllers - DJI ones only work with drones that have O3 on them so if you want to fly a whoop

Radiomaster Boxer is probably the goto one for FPV quadcopters. If you want to fly LoS and autonomous missions then Radiomaster TX16S (large touchscreen, community support, all the LUA tememetry widgets you could ever want). For the link, i

You hardly need gpio pins for anything these days, it's usually better to use usb native comms or a uart converter or an i2c bridge etc. The added bonus is that you won't burn the expensive Pi when something goes wrong with the pe

I own one and I can assure you it’s very easy to fall on your back if you overestimate the friction when braking aggressively. Not even close to real life bike braking with disc brakes if you know how to transfer your weight properly (grant

In theory, the braking performance could be the same as the bicycle. In practice, the rider needs to guess the traction very precisely and to move their weight backwards to an angle just a smidge higher than arctan(static friction coefficie

Yeah, it’s easier to use lab test data from Mavic Mini 3 specs: 51 minutes flight time at 21kph [0]. The battery capacity is 28.4Wh [1]. So, 18.4/(21*51/60) = 1.6 Wh/km. Assuming US is 2800 miles (4500 km) wide, we get 7.2 kW

I’m saying the physical actuators that turn the steering wheel when LKA is on are torque limited on purpose, so they won’t be able to make a sharp turn or overpower a human, even if they won’t disengage when a human tries to override it (e.

Yeah, my info was based on George Hotz interviews on Openpilot. He said they are safe because even if the software wants to steer the car off the road, the lane keep assist actuator won’t be able to steer that hard and will disengage. Haven

Soldering skillz are always nice to have but the amount of Chinese 'USB C' gear that skimp on the 5.1K resistors is truly enormous, and adding them gets old really fast. Some designers even combine cc1 and cc2 to save 0.01¢ on the

ESC (basically same actuator hardware as ABS) can definitely brake without user input and it's mandatory in all cars sold after 2012. Steering assist is mostly torque limited by design, you should be able to easily overpower it.

NTSB cannot do that, it can only issue recommendations that could be acted on (or ignored) by the FAA. Maybe Boeing execs are sure their FAA buddies are not going to do anything drastic like that anytime soon? It’s not like Boeing the main

It even supports WiFi, so you can have automatic backups every night while the phone is charging. Also the protocol has been reverse engineered, it’s possible to use a Linux server instead of having to use iTunes on windows or buying a Mac.

DJI/Caddx are using basically LTE radios, I doubt WiFi chipsets will have acceptable perf. Still, for fixed wing this might be acceptable and cheaper than existing systems. For freestyle/racing.. forget it.
