Minimum Viable Arduino Project: Aeropress Timer

My trick is to re-use the filters. After the first few presses, the filters clog up somewhat and coffee doesn't drip through them as fast. So you can stir and let the mixture sit for a while, without resorting to maneuvers like the inverted method, which are unsafe for groggy programmers who haven't had any coffee yet that morning.

But, I thought Arduino had become officially evil once it joined Qualcomm. Besides which a Raspberry Pi Pico is cheaper than any Arduino-branded board ever was. So I'd just program this type of thing in MicroPython.

I do see that in the article, the project used an Adafruit Trinket M0, a very cute little board that has CircuitPython already installed. So I wonder why not just use CircuitPython. Anyway though, it's a Cortex M0 board, rather than the traditional Atmega that the Arduino world grew up using.

They have - but for less technical users their IDE is not too bad, and there are way too many bits out there relying on it, including lots of stuff not arduino, plus it's open source. And as it reloads files on changes can be used with a real editor as well. So for the software side I'm inclined to stick with that thing.

For hardware side it's different - but every interesting arduino has shitloads of clones available. In the past I've been buying those only for special use cases where there were no genuine arduinos to support the project - now since they got crazy it's only clones, and whenever I touch any of my old projects I'm updating the list of materials to recommend buying clones. You can still get nano clones for just a bit over 1 EUR each, so for projects where that is enough that's hard to beat value for the money.
