Hi Tildes,

I'm looking to introduce my children (aged 10 or so) to simple electronics (blinking lights, simple sensors, ...). I've played with Arduino in the past, but I see that there are now many competing options: Arduino, cheap rip-offs, RPi zero, adafruit, ESP32, ... It's easy to get lost!

Which do you recommend? Ideally, I'd like something cross-platform and open-source, easy to set up (ideally a kit with everything included), and of course not insanely expensive.

Edit: thanks everyone for the good advice! There are so many good options...

If you want to, feel free to find the thing you're talking about and link to its pages on Anilist, MAL, or any other database you use!

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

The Showcase has now been live for a week, and I'm thrilled with all the incredible projects that got completed this year! Congratulations to all participants!

While the experience is fresh, I want to gather some feedback for next year's Timasomo. Use this thread to identify:

• Positives
• Negatives
• Tweaks
• Suggestions

Basically, what should we keep the same for next year, and what should we change? Feedback is welcome from anyone, but in particular I'm interested in hearing from Timasomo participants.

Also, I put this out there last year and I'll put it out again this year: if anyone is interested in running Timasomo for 2022, please let me know! While I'm happy to run it and can certainly do it again next year, I do think it's important for events like this to have community ownership and not be dependent on one particular user. I think it is more sustainable for the community if there is a sense of distributed/shared responsibility. Thus, if you have any interest in managing the event, please let me know either here or by PM.

This thread is posted weekly - please try to post all relevant US political content in here, such as news, updates, opinion articles, etc. Extremely significant events may warrant a separate topic, but almost all should be posted in here.

This is an inherently political thread; please try to avoid antagonistic arguments and bickering matches. Comment threads that devolve into unproductive arguments may be removed so that the overall topic is able to continue.
