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…
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…
Really neat clean code! 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…
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…
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…
I think the most recent surge is due to LLMs, the only way to (easily) apply them is to have some form of code like textual representation of your problem domain so "circuits as code" is the obvious way to wedge them…
The article links to a Linux implementation that does it with off the shelf WiFi hardware. You do need specific features in the hardware/firmware, but there are consumer devices that have that e.g. Atheros AR9280.…
The cable is cooled by a mix of water and glycol, which runs through the cable and also cools the connector pins. Tesla use this in their supercharger cables, as without it the cable would be too heavy.…
Marimo does this for python, by tracking dependencies. https://marimo.io/
This is really well documented with lovely schematics, and the link in the github to the proper "korg style" toggle switches [1] on AliExpress is worth the read. The code [2] is very nice as well, showing how clean a…
Smallest Swissbit do is 512MB, but that's as it's SLC flash so far lower capacity. https://www.swissbit.com/en/products/product-finder/products... Looking at pricing, 1GB is only about 25% more in unit quantity.…
Brushless drone motors suffer from too high a kV (~operating RPM), needing a lot of gear reduction for this kind of application, but I take your point about volume. Gimbal motors (also in drones) are closer to what is…
Reducing the RAM requirement to 8GB to fit this on my Macbook Air M2 (with room left for other running apps), I get the same figure (66 GB/s) regardless of the number of threads. If I actually set it to the size of…
You can "freeze" micropython modules and have them saved in flash with Micropython, where flash only stores the precompiled bytecode. If your module contains stored data in the form of an immutable object, like a string…
Some other existing options in this space (not all web based) are - https://pymeasure.readthedocs.io/en/latest/ python Framework for running science experiments, getting hardware to go through a set of steps and plot…
If its "just storage", how is it any better for this application than a zip file?
This sales pitch ignores cloudflare workers, which sound pretty similar to me, with both webassembly and key-value storage. The distinguishing part of the articles option seems to be that webassembly functions are…
Texas Instruments has also done interesting work in this area with "Compute Through Power Loss" where they use the non volatile FRAM in some MSP430s as working memory [1] I don't think it needs the kind of compiler…
There is the mikrobus, grove, and qwiic connectors, all of which will be GPIO, I2C and likely (for Mikrobus) SPI as well. The reason the SoC says "up to 170" as they are multiplexed with the ethernet, display and camera…
Its (presumed) competitor, MIPI-CSI is not open source either. SLVS-EC looks easier to interface with an FPGA at least, presumably the voltage levels are closer to standard, unlike MIPI D-PHY's exotic dual level…
For production,its best to specify the important properties as you say, then let the contract manufacturer figure it out, rather than spend ages finding the cheapest 100nF 10V X5R 0402 cap. If it really matters, then…
There is hardware available with the same microcontroller (ESP32) in a thick watch style case, but I don't know if anyone has ported meshtastic to it yet. On the face of it, power usage looks a bit higher due to the LCD…
Very interesting how they made this work on iOS, given so many failed (before the Apple/Google protocol was released). A lot of the design documentation references the UK market, I wonder if VMWare were…
The DDC interface, which is an I2C bus that allows for bidirectional communications to read EDID data, so you know what you are plugging into. Hot plug detection via the HPD line, so you can tell if you are plugged in…
