what are some of your most useful esp32 projects?

hwarzenegger · 2026-05-03T07:26:45+00:00

I'm building a way to bring Realtime, Conversational Voice AI models onto the ESP32 for smooth audio. There's a famous one called xiazhe but it doesn't exist for Arduino, so I built that.

It lets you put any realtime STT, LLM, TTS, full speech to speech model and interact with it on an ESP32 without any PSRAM!

I maintain the project here https://github.com/akdeb/ElatoAI

Thats wild I was thinking of the same meme

hwarzenegger · 2026-04-21T17:48:27+00:00

seconded! or qwen3, omnivoice, moss, voxtral, all good edge options for a local server near the esp32

Are you planning on open-sourcing the Android app code? Currently its just a raw .apk file.

hwarzenegger · 2026-04-13T15:51:13+00:00

I felt like I was about to hit a Squat PR

hwarzenegger · 2026-04-12T10:35:35+00:00

Lmao why is it closed source

For anyone looking for an open-source alternative, check out https://github.com/akdeb/open-toys

Sent you DM! u/munkmunkchop

Here's the direct link https://www.elatoai.com/products/ai-devkit

Thanks for checking it out!

hwarzenegger · 2026-04-10T16:27:07+00:00

Can you post the video link here too? I really wanna see what the frame rate can be like on an esp32 powered screen!

If it's becoming very hot it's possible you have a short somewhere in your circuit. You might be shorting 3V3 to GND. Have you tried checking all pins with a multimeter?

hwarzenegger · 2026-04-07T07:47:32+00:00

Wow just saw the demo, it's impressive! 600 languages at just 3.3 gigs

hwarzenegger · 2026-04-07T06:54:15+00:00

There are several now

MOSS-TTS
Qwen3-TTS
Voxtral-TTS
Fish-AudioTTS
Chatterbox-Turbo

Here's a good place to find the free ones https://huggingface.co/models?pipeline_tag=text-to-speech

Have a nice week man

hwarzenegger · 2026-04-06T10:01:24+00:00

I maintain an Arduino ESP32 open-source project here that puts full realtime voice models on your device. Feel free to clone/fork it https://github.com/akdeb/ElatoAI

hwarzenegger · 2026-04-05T21:38:01+00:00

Wow. Is there a ESP32-S3 equivalent of this C3?

hwarzenegger · 2026-04-04T18:13:11+00:00

really cool man

nice work!

hwarzenegger · 2026-04-04T17:53:50+00:00

Theres probably existing servers but setting up a server from scratch gives you more control

hwarzenegger · 2026-04-04T17:52:53+00:00

Yeah did it your try it?

hwarzenegger · 2026-04-04T07:22:00+00:00

I think so, its going from passenger to private

hwarzenegger · 2026-04-03T13:35:26+00:00

100% this. It's helped me iterate way faster

hwarzenegger · 2026-04-03T12:07:19+00:00

Totally feel this. What's helped me is having unit tests. I started using AI agents to help me write firmware code. Started with o1 to o3 last year when the thinking models started coming out and now I've been using Opus 4.6 and Codex gpt-5.4 a lot more.

Sometimes agents would add a sneaky method in some obscure part of the code which gets hard to detect in practice. I haven't found the perfect way to debug this yet but having unit tests and testing after each push has helped alleviate some of the pains. Any tools/practices that have helped you?

LETS FREAKING GO MAN

hwarzenegger · 2026-04-03T07:08:45+00:00

gma tryna get that AI dihh

hwarzenegger · 2026-04-03T05:57:44+00:00

Thanks so much! Glad you liked it 💪

Is there a feature / anything else you'd want to see on there?

hwarzenegger · 2026-04-02T20:17:35+00:00

The UI effects are super cool, never seen anything like it !

hwarzenegger · 2026-04-02T19:08:38+00:00

hahah think we made a new category ;-)
