Many airlines are going much further than this, for instance Virgin Atlantic ban you from either charging or charging from any power bank, and you can't keep them in the overhead locker, you must keep them next to you in case it starts burning spontaneously!
They have a "fire containment bag" they can chuck it in should you notice it getting hot or smoking.
TFA does directly mention the NPU "Arm-China Zhouyi: 30 TOPS (Dedicated)"
"you cannot simply use standard versions of PyTorch or TensorFlow out of the box. You must use the NeuralONE AI SDK."
Neon is a SIMD instruction set for the CPU, not a separate accelerator. It doesn't need an SDK to use, it's supported by compiler intrinsics and assembly language in any modern ARM compiler.
I like the single C file, but Docker if you want all the examples approach, that's really convenient for embedded.
Test coverage looks good as well, be interesting to see the metrics.
This would be quite cool for adding scripting to medical devices, avoiding the need to revalidate the "core" each time you change a feature.
An interesting comparison would be against an embedded WASM bytecode interpreter like https://github.com/bytecodealliance/wasm-micro-runtime, which is still much larger at 56.3K on a Cortex M4F.
Maybe WASM is just a more complicated instruction set than the smallest RISCV profile?
It would be operating off rectified DC (like an induction hob) or using a SMPS operating at ultrasonic frequencies to deliver a lower DC voltage, you wouldn't get the 50Hz buzz even if there was a transformer.
The best part I find about ChargerLab teardowns is identifying all the passive and discrete components.
Western distributors tend to only stock western/japanese brands of these, but they can make up a sizable fraction of the BOM (especially electrolytic capacitors) so knowing who the big players are comfortable with using is very handy. LCSC stock a lot, but its nice to know which suppliers have been proven in use.
It can, it just needs the two resistors, which is the cheapest possible thing the standards committee could have asked manufacturers to do.
USB-C gets complicated at the high end, but for basic functionality I think the standards committee did a very good job at making the cheapest way to do it the correct way, e.g. a USB-C to 3.5mm audio adaptor can be entirely passive, it just needs the right resistor in it.
