Hi HN, I recently shared this on r/BCI and wanted to see what the engineering community here thinks. A while back, I got frustrated with the state of accessible BCI hardware. Research gear was wildly unaffordable. So, I spent a ton of time designing a custom board, software and firmware to bridge that gap. I call it the Cerelog ESP-EEG. It is open-source (Firmware + Schematics), and I designed it specifically to fix the signal integrity issues found in most DIY hardware. I believe in sharing the work. You can find the Schematics, Firmware, and Software setup on the GitHub repo: GITHUB…

Hi HN, I built EEGFrontier, a compact open-source EEG acquisition board based on the ADS1299 and an RP2040. The goal was to design a low-cost board that works with dry electrodes while exposing the full EEG signal chain — no abstractions, no closed firmware. What surprised me most during this project were the practical issues that datasheets don’t really prepare you for: grounding (REF/BIAS), noise coupling from digital lines, routing constraints, and how small layout decisions drastically affect signal quality. The repository includes full KiCad files, firmware, a BOM with cost…

As part of a little research and also some fun I decided to try my hand at seeing how small of an ESP32 board I can make with functioning WiFi.

I recently learned about some fascinating research done at MIT for potentially treating Alzheimer’s using light and sound stimulation at 40 hertz. Nothing has been proven yet, but it seemed compelling to me, especially given the safety and simplicity of the treatment (i.e., no drugs, no electrodes, just looking at light and hearing sounds). I wanted to try it myself, but was surprised how hard it was to find something free and easy to use to generate such pulses. Which is odd because I remember some freeware DOS program I tried back in the 90s which did all this kind of stuff (anyone know…

hi! video[0] The idea is you could carry around this hardware and ask it any questions about the conference. Who is speaking, what are they speaking about etc... it connects via WebRTC to a LLM and you get a bunch of info. This is a workshop/demo project I did for a conference. When I was talking to the organizers I mentioned that I enjoy doing hardware + WebRTC projects. They thought that was cool and so we ran with it. I have been doing these ESP32 + voice ai projects for a bit now. Started with an embedded sdk for livekit[1] that jul 2024 and been noodling with it since then. This…

Hi HN! This is an SDK for ESP32s (microcontrollers) that runs against OpenAI's new WebRTC service [0] My hope is that people can easily add AI to lots of 'real' devices. Wearable devices, speakers around the house, toys etc... You don't have to write any code, just buy a device and set some env variables. If you have any feedback/questions I would love to hear! I hope this kicks off a generation of new interesting devices. If you aren't familiar with WebRTC it can do some magical things. Check out WebRTC for the Curious[1] and would love to talk about all the cool things that does also.…

We built the smallest dual-band aircraft trackerfrom $48/mo▲95I grew frustrated with closed source ADS-B receivers a few years ago, and wanted to build a true low cost embedded ADS-B receiver from scratch for low power applications. I ended up developing a custom radio frontend that uses RP2040 PIO for Mode S preamble detection and demodulation, and also released the first open soruce implementation of UAT decoding on an RF MCU from TI (which works somewhat beyond the publicly stated specs for the chip). Today, ADSBee is a fully featured dual-band ADS-B receiver, with Mode S, ADSB, UAT ADSB, UAT TIS-B / FIS-B, a ton of configurable reporting…
