Hmm I was just going off the Firefox estimate, maybe there's some browser difference?

Good point - are there any low cost or at least widely available integrated IC receivers? There's the MAS6180C but that doesn't seem to be commonly available at any of the big distributors. GPS works, but then your clock needs to

I don't understand why in the age of dirt cheap Espressif modules people keep doing DIY clocks with micros that don't have WiFi for S/NTP. It's the same with a lot of the expensive nixie clocks. At least throw in an RTC!

Unfortunately a lot of engineers who do this don't appreciate that flash has limited write cycles, and the issues with upgrading non-reproducible systems down the line.

Yes, excellent point regarding secure boot (for good or for evil)!

Openwrt also makes an excellent base embedded distro - it's designed to run from a read-only root which is important for any serious embedded device, whilst still having the ability to add packages. The common ringlogger simplifies sys

Just in case this puts anyone off motorcycles: - Uphill starts are easy compared to a manual car as you operate the rear brake and accelerator using different parts of the body - Stopping facing down a slope requires the use of the brakes a

Another possible confounding factor is that these aircraft have different operational profiles. The 747 variants were likely be to employed on longer haul routes whereas a 737 will be doing multiple individual flights per day in more crowde

If your router supports OpenWRT that's a good alternative that doesn't require any additional boxes/boards and is simpler to set up networking-wise. There's a nice UI that generates the QR codes or config files ready for

KiBot [0] is super handy for this, the documentation has an explicit section on CI/CD usage. It does have to basically script drive the GUI to achieve some functionality which has now been added to the kicad cli, so hopefully going for

Some of the marketing mentioned private keys so I stupidly assumed a per transmission negotiation mechanism but of course they probably just mean "symmetric key". A per tag key extraction would be annoying though presumably. The P

Nice article - is the idea to communicate with the tags with their stock firmware using another CC25x series chip or dev board? Unfortunately, that might be tricky without the private keys in the controller. User manual [0] describes a per

Having worked with both the ESP-IDF experience is far better than Cube MX or even HAL. FreeRTOS is properly integrated out of the box, and stateful drivers are implemented as FreeRTOS tasks. There are decent escape hatches if you need to ge

Personally, I'd would say another advantage is sdk. IMO ESP-IDF is up there with Silabs and nRF in the top tier of dev experience. Then STM/TI etc and Microchip a very distant last. The ESP32 isn't ideal for basic battery stu

I run Openwrt on an Edgerouter-X nowadays and it's rock solid. Has same/better routing perf + stability as the original ubnt firmware, but with native wireguard, full package management, a much better UI, much better configuration
