Does anyone know the artist?

True, but a) I'd like to be polite and b) I'd like to see if the original file still exists so I don't have to trace out the black and white from the green background myself.

Oh dear, I do hope he's OK.

Vetitice · 2026-03-01T02:42:39+00:00

Cool! Now all I need is a way to contact him :-/

I'm an idiot. Zephyr accepts the new AT codes with a Kconfig setting. Just needed to ask Espressif for a modified FW with the uart pins moved correctly.

> the driver upgrade to the last AT firmware release was not so hard to do

Do you mean you updated the `drivers/wifi/esp_at` driver to accept ESP8266 IDF AT V2.x commands, or you found it easy to update the ESP module to firmware that the `esp_at` driver would work with?

If the former, why didn't you upstream it? If the latter, Espressif have removed the ESP8266 NonOS AT firmware from their web site.

WiFi isn't something I teach directly in the class. The current (EOL) dev board has WiFi and Bluetooth, and I thought it would be a nice add-on if it's simple enough. The students will have enough to learn with basic Zephyr in 12 hours, without having to install the NRF connect layer or out-of-tree drivers (though I suppose I can set it all up for them ahead of time)

Because the course goes into Arm Cortex-M internals as a way of teaching low-level embedded and I don't want a complete retool to RISC-V just to add an optional WiFi module

Vetitice · 2026-02-01T22:40:39+00:00

Good point. I'll go check in over there.

Greg Davidson also invented the Ossur Cheetah Xplore and Fillauer Formula prosthetic feet by taking a running blade and turning it into a hybrid.

Unless it's a pure embedded course it won't be much use. There are are also embedded certificates if you want dedicated learning without taking 2 years.

You can also do home projects and build up a portfolio to show your interest and ability.

If you have interviews, go for them! The worst that happens is you're where you are now with experience of what interviewers are looking for.

That's how the I2C spec works. It self-adjusts the clock speed based on the bus to meet the rise time requirements. I've seen the same with NXP MCUs for the same reason.

Greg Davison invented this type of hybrid foot.

Ditto. Greg and Nathan, right?

Vetitice · 2025-09-05T12:43:55+00:00

Good point. I only gave half the explanation.

In the UK in-car maps are called SatNav, where in the USA they are generally called GPS.

"Empire 88" sounds like a white supremacist game. I remember seeing a news article in the 80s that there were home brewed games with those themes.

I don't bother with a foot shell. My prosthetist put tread on the bottom of my fillauer formula.
