Project mention: Show HN: AI Toy I worked on is in stores, media code OSS | news.ycombinator.com | 2025-10-131.) Not something I did. I only worked on the software.
4.) Contracted because I wrote the Open Source libraries it uses. I created https://github.com/pion/webrtc and https://webrtcforthecurious.com the company reached out to me because https://github.com/sepfy/libpeer didn't work with Pion. Turned out to be a libpeer bug (which I fixed)
> were you really hooked
I have been doing hardware + WebRTC with lots of different projects since then. https://www.youtube.com/@seandubois86 unpaid, that's my proof at least :)
> Hooked on the technology stack.
Yes I enjoy doing WebRTC + C https://github.com/awslabs/amazon-kinesis-video-streams-webr... (one of original authors) so I enjoy the tech a lot.
> Hooked talking to Santa
I enjoy the unexpected behaviors of Voice AI at this moment in time. In the video I asked Santa about pi, and it responded in a way I didn't expect. I find it absurd/entertaining.
> Do you have kids that you built it for
Yes. I have a few toys/personalities that I built for my kid. They make up funny scenarios/personalities and I change the prompt and put it in a different toy. It's fun.
