I hope FUTO does start caring about language support, because for example their AI powered text prediction is only available for English. I'd happily train a model for them in my native language if they provided instructions on how to do so. And I'd help with swipe typing too.

That solved the problem of ads in games much better than DNS :D

Some suggestions: - What I miss from NAND Game is the challenge of optimizing for efficiency. You'd build a component and it would let you know if it could be built with fewer NAND gates and you'd try to simplify the circuit. For example, while I did "NAND it" with 4 transistors, I did "The dual" with 5 and given the explanation I got afterwards I could have used one less. - This definitely needs to get better on mobile - The description for the first level using BitLine and BitLineBar (I think that was the Sense Amp?) doesn't really explain what it's supposed to do and I had to deduce it from the truth table.

100% this. I had a very, very miserable time setting up two systems and trying to get them running a version that was supported. The worst part is SBCs that stop getting OS updates and become permanently locked in to a specific version. Which also forces the rest of your hardware to use the same version. Using a Jetson Nano with Ubuntu 18.04 in 2022 was lots of fun...

Last year I met a couple of university students working on a robot and out of curiosity I asked what they were using as a microcontroller and the software stack. They were running ROS. When they said they still hadn't upgraded to ROS 2 yet, I could feel their pain...

I started robotics at a young age and began with small builds with LEGO motors and sensors, getting a feel of how each one works and how to interact with them with code. Then I got to much more advanced programs with LEGO Mindstorms EV3, learned about things like PID controllers practically and even started taking part in some competitions. Next, I went to writing actual code (as opposed to block-based programming) on microcontrollers like the micro:bit (and a few years later the Raspberry Pi Pico). I deepened my knowledge of how electronics work and learned how circuits work. I eventually got into a team with a few friends and we built a human-size robot combining 3D printing, a bunch of circuitry, ROS, 2 SBCs, Arduinos, a LIDAR and OpenCV for face/object recognition. This took years of learning step-by-step to achieve.

This is obviously not the path you'd take, robotics was what brought me into programming and you're probably going for the opposite.

You're not going to build a perfect robot or electronic device from the start and you shouldn't try to either. Get a microcontroller that's newcomer-friendly and play around with it. A micro:bit mostly emphasizes on the end result, with a built-in display and sensors and many plug-and-play modules to get you going. A Raspberry Pi Pico is much more flexible, but also requires you to learn about wiring and doing more things yourself. If you prefer coding in C, go for an Arduino. An ESP32 is also a good choice. It's a good idea to get a 3D printer and learn CAD in parallel, as it's a great way for a hobbyist to create actual tools that are more than a bunch of wires.

Once you get enough experience and confidence in your skills, you'll want to get into more advanced projects. Use your knowledge to plan them out, research and learn the technologies you're going to use (you can't learn everything beforehand and each piece of hardware is something different) and enjoy the journey from prototype to finished project.

And by the way (you didn't mention it but other comments here are so I'll give you an opinion on that), ROS is nearly always overkill for hobbyist robotics projects :D

I hope that helps you start your journey!
