@niclas yea it does, its a plug-in system. You just plug it into an outlet.

@whitequark oh damn I'm really out of the loop. I vaguely thought Firefox was already using Servo, didn't know it was never quite finished.Mozilla is really taking a bad turn, probably for the better it moved under different governance.

I am kinda impressed with the 100% paper packaging, not even a plastic film on the display

Oura Gen 3 charger PCB. Am interested in figuring out how it works. It's a surprisingly expensive item (69€).On the back (which is facing upwards when installed into the charger) is this IR transceiver/receiver. It seems to communicate via the rings IR diodes which are normally used for SpO2 measurements.

Luckily fairly easy to trace board.The IR part seems to be a Vishay "BELOBOG" series IR receiver. So no sending, just receiving. I could imagine that its just to signal the charger about state to give feedback to the user via the status LED (e.g. done charging, pairing active etc). The voltage on the charging coil is about 22V in respect to GND and modulated at ~7MHz

I have the Oura charger fully reverse engineered by now and drawn up a schematic. Some capacitor values are guesses but circuit wise thats basically it. The LED bit confuses me, why do they have two GPIOs hooked up to each color of the RGB LED. One with current limiting resistor and one directly??

My updated scribbles. I do most of the reverse engineering in Photoshop.

The tension on the AM5 socket clamp is *intense*. I've never been this scared to clamp down a CPU.

You get these USB4/TB to PCIe adapters based on the ASM2464PD for around 50€.You can do non SSD stuff too as it is true PCIe tunneling and not a USB MSD to NVME bridge.So any PCIe device (even GPUs) work, including this SATA controller.The upcoming ASM2464PDX will also support birfurcation.F.e.:https://s.click.aliexpress.com/e/_EGbYHss

Reminder that PDFs can have file attachments. Esp. with datasheets they sometimes hide useful data.

Local trains are a fuck atm so put the folding bike setup back together. Nothing better than bikes to have a dependable last mile transit.

Qualcomm is easily the worst company to work with for any product if you are not a large established company. Not great to have them slurp up Arduino.Like even if you paid them for their god awful SDKs they are still actively hostile towards you as a customer.The only reason to work with them is because they bought up any leading IC solution in any mass market space. So if you do consumer electronics you have to deal with them sooner or later.https://www.qualcomm.com/news/releases/2025/10/qualcomm-to-acquire-arduino-accelerating-developers--access-to-i

From the NTSB investigation into the Titan submersible, thats the internals of some super expensive commercial deep sea camera they used and it contains some redacted @adafruit Qwiic/Stemma board and a Teensy 3.2Very funny that they requested to redact the markings.

Increasingly glad I bought all the RAM I need for the next few years a month ago...
