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.

This project is an RF Signal Scanner built using an ESP32, AD8317 RF detector, and various other components. It's designed to detect and measure RF signals in the environment and display the signal strength on an OLED display. It's useful to find hidden cameras, wiretapping devices, and other RF-enabled devices.

I've been trying to make accessible and beautiful GPIO pinouts since I started one for the Raspberry Pi in 2013 [1]. I've since given the Raspberry Pi Pico [2] and Pico 2 [3] microcontrollers the same treatment when they launched. Recently I've updated these with a new "Upside-down" view to complement the rear view, giving a pinout in the right orientation to match your project. The Pico sites are all hand-coded single HTML pages with supporting CSS and minimal JS. They are set up to optionally install as a "Desktop" web app. They also degrade into a somewhat usable table in lieu of CSS and…

This is a projected I started that blends both the fun of playing a split screen multiplayer driving game and controlling real rc cars. The cars can also be controlled via bluetooth gamepads and is meant to be easily hackable.

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! me and my friends together built an 8 bit CPU implemented in Logisim purely from scratch. The control unit of this system does not implement the generic microcode ROM or any kind of RAM. This was made purely from discrete logic gates and coded the system to run different programs. key features: Custom 16-instruction Harvard ISA, 8-bit fixed format, 4 general purpose registers Hardwired control unit built entirely from AND/OR gate logic matrix Dual-phase clocking to eliminate race conditions Bootstrap Control Unit that cold-boots via ROM-to-RAM transfer Early-exit conditional…

Hi! My name is Ben, and I recently updated my audio dev board "Sonatino" after receiving a lot of good feedback from the initial launch a year ago. I began working on this after building a few projects that required audio capabilities. I was getting tired of wiring up external DACs and amplifiers to ESP32 boards, so I decided to look for a more compact, integrated solution. The available options either had larger footprints, non-standard connectors, or features that I didn't typically need for my projects. That's when I started working on a custom PCB that could be a sort of "audio swiss…

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.…

I made an alarm clock that blows up capacitors to wake you up. There are more details on the Github repo but it's made from an esp32-c3 as the microcontroller, with 3 capacitor slots. There are relays on each capacitor slot to put 15v reverse voltage on the capacitor, with 5.1 ohm resistors on each slot for current limiting in case the capacitor shorts out. I also chucked in an SSD1315 OLED to show the time and a menu to configure it, although there's a web UI as well. The esp32 also means you can fetch the time from NTP. It also functions as a small heater since I used LDOs to step down 15v…

A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to…

Hi everyone. I've recently released control-components, a C++ library I've been using for most of my embedded projects. It is written in C++17 (with some features from C++20) and uses STL and FreeRTOS under the hood. It contains a lot of building blocks that is commonly used in embedded and IoT projects: finite state machines (FSM), various counters, synchronisation primitives, system loops, sensors, schedulers, HTTP, WiFi, Web GUI, and much more. It also provides GitHub CI workflows for build automation (ccache, various checks). In general, it's a good starting point for an ESP32 project.…

It's been a while since this ESP8266 VNC Client library has been out. https://github.com/Links2004/arduinoVNC Today I finally got my ILI9341 display, so tried to set it up as a remote display for the Raspberry Pi. Here's a demo video and photo. https://www.youtube.com/watch?v=aVFWgACP6sw https://www.instagram.com/p/BDJwURSkdY_/ On the Pi, all you need to do is start a TightVNC server, something like this vncserver :1 -geometry 320x240 -depth 16 -name "ESP VNC :888" -alwaysshared -s 0 -nocursor -broadcast The ESP8266 connects…
