This is incredible - I definitely wanted to do the same for my kid once he gets a bit older so I'm bookmarking this.
I read through the whole thing and found it informative, LLM or not. To all AI low effort naysayers I think for a working parent this maybe would not have been possible to write in reasonable time without the aid of Claude.
You can just buy a ready project, its called Toniebox here in germany and I think its also available in america and maybe other countries..the figures that contain the rfid chip that then access the cloud stuff are kind of expensive but if you inclined to hack your way you could get a second hand tonie box and then go with teddycloud..saves you probably some engineering steps and its a proven platform with community
edit2: I just realised that I got an emotional reaction to this. This guy, the one who slopped the article, knew that the toniebox existed. But instead of researching if there is an existing project, or some way to contribute to someone else, decided that he wants the fast dopamin and build his "own" thing which is in the end a slopped copy of something that already exists in a mature ecosystem with a lot of support officially and inofficially. But that wasnt good enough for the ego here. I am projecting hard, but that is how emotions during the first coffee work
love it! incredible! and you got it to work at first attempt!
i really need to start to find time to my own unfinished..or not started projects that are little bit similiar.
annd you made your own pcb?! what the actual .. i was thinking that's something you'll need to have years of experience and 5 revisions
This is an excellent project! Congrats and thanks for sharing! (LLM writing notwithstanding)
I wonder if it would be a good base to create a kids phone / yogurt-cup telephone: no screen, no keyboard, just a box and figurines, and to call someone up you put the figurine on the box. It could be boxes-only (only people with a box can call or be called) or it could be more general: kids only have boxes and figurines, but the machine is able to call actual phones.
First off - well done, this is amazing. Secondly, it's a fascinating read how you basically figured it out, one mistake at a time, like not connecting or fastening the battery correctly. This is the way! We make mistakes and figure things out in our journey to make something interesting, and learn along the way.
This is really sweet. Reminds me of an old client I worked for called Museum in a Box (https://museuminabox.org/). It was started by George Oates (ex. Flickr).
3D printed figurines on top of a box which would activate museum style narration and multimedia. It was based on a Raspberry PI though which is different from this project but in many ways, it was the same.
I am mostly into software my whole life. I want to dabble with hardware and electronics in the future and this post taught me many things that’ll be very useful when I do.
Tnx for writing every bit of the building process in an easy to understand way and also open sourcing it.
I absolutely hate AI writing as well, but I suspect since the author is French, and the underlying code in their GitHub project [1] uses a lot of French naming, that it was more of a translation aid.
I wanted to give my three kids a screenless story box (inspired by the Toniebox gesture) but I was deeply annoyed by the closed ecosystem and subscription-like models of commercial alternatives.
So, despite knowing absolutely nothing about electronics three months ago, I decided to build one myself using an ESP32, an NFC reader, and a Bambu Lab printer. I learned everything the hard way, from accidentally creating short circuits to routing 491 tracks by hand on my first custom PCB with KiCad (and using Claude to double-check my math).
The box serves its own local web page to upload MP3s/M4As, streams web radios, and handles self-updates over Wi-Fi with a built-in safety net in case the network stack crashes.
Everything is fully open-source (firmware, KiCad files, 3D models under MIT license) on GitHub: link in the article
I’d love to hear your thoughts, feedback on the PCB routing, or answer any questions about the build!
I'm planning something like this. I already have Home Assistant with Music Assistant working, so playing radio and music and audiobooks in rooms are already possible with my phone. I plan to add ESPHome device with NFC reader to trigger plays so it's easy for the kids to use it. Just need to find where I left my roll of 50 NFC stickers.
One suggestion: In my opinion, kids nowadays are very familiar with charging devices with USB-C. Powering the device with USB-C will be much easier. Worse case scenario, I'll use some small portable power bank and place it inside.

Kudos to the author.
edit: the author actually references the toniebox but as I hate him by default because of his slop, here a link https://forum.revvox.de/t/teddycloud-cc3200-newbie-guide/925
Here some ccc presentation: https://media.ccc.de/v/37c3-11993-toniebox_reverse_engineeri...

I think even as an adult I would enjoy that.

I liked the look of your box too. Keep up!
You’re not buying a player, you’re buying a subscription [...]
I particularly hate the first one, don't AI sloppers notice how horrible it is to read "No x, no y, no z"?
had to stop reading from that point onwards.
