Strip LED Controller for ESPHome
Nov 09,2025
This PCB allows controlling 7 LED strip channels up to 24V and 10A per channel. I use it to control a RGBCWWW color stripe and a CWWW white stripe with the same device. It also has an input for a push button.I use it with ESPHome but any other ESP32 based firmware should work,

ESP-AirSense SCD30
Quispe Nov 07,2025
Indoor air monitor built on ESP32-WROOM-32, 1.8″ TFT 128×160 SPI (ST7735), and Sensirion SCD30 (NDIR). The SCD30 measures CO₂ in 0–40,000 ppm (typical calibrated band 400–10,000 ppm). Firmware samples every 2–10 s, applies ABC (Automatic Baseline Correction) and supports manual offset calibration (e.g., outdoor ~400 ppm) so you can set a “healthy” target (commonly ≤800 ppm) and derive clear ventilation guidance.On-device UI sh...

DIY Meshtastic Using ESP32 : Build Your Own Private Off-Grid Network
Joseph Nov 01,2025
Project OverviewThis project delivers a complete, custom-designed PCB solution for building Meshtastic mesh network nodes. Unlike traditional communication methods that rely on cellular towers or Wi-Fi infrastructure, this device creates decentralised, long-range networks using LoRa technology. Multiple nodes automatically relay messages between each other, extending coverage across vast areas while consuming minimal power.The Problem It SolvesStaying connected in remote locations has always bee...

Xbox Controller with ESP32
Arnov sharma Oct 31,2025
Greetings everyone and welcome back. here’s something I’ve been really excited to share.I’ve been working on a simple but powerful setup that connects an Xbox controller to an ESP32-C6 DevKit over BLE and displays all the input data live on an ILI9341 SPI screen. It started as a way to visualize controller input—buttons, triggers, and analog sticks—in real time. But once I saw how responsive it was, I realized this could be much more than just a visualizer.The real reason behind this build is a ...

From Unboxing to Coding - Radar Clock on Elecrow’s 2.1 HMI Display
Pavleski Oct 24,2025
Today I received a shipment with a large round LCD display from Elecrow. The device is packed in two boxes so that it is fully protected from damage during transportation. Inside there is a display, a USB cable for power and communication, as well as an additional cable for connecting an external module. This is CrowPanel 2.1inch-HMI ESP32 Rotary Display 480*480 which has some really impressive features:- high-performance ESP32-S3 chip- WiFi and low-power Bluetooth- capacitive touch screen ...

CustomBoot-32
Oct 23,2025
The project focuses on creating a custom PCB that integrates the Blue Pill (STM32F103C8T6) with ESP32 WROOM-32E.The ESP32 hosts a website, receives two firmwares via OTA, creates memory partitions, and initializes a File System in one of the partitions.On the STM side, a dual-image Bootloader requests firmware based on user input, verifies it, allocates it in flash memory, and executes it.The firmware transfer is carried out via UART.

Gravitymon PCB for ESP32c3 Zero PET
Oct 22,2025
Gravitymon is a electronic hydrometer software that can be used to measure gravity and temperature duringfermentation of beer and report the progress to a number of external services. Is uses a gyro to measure thegravity since there is a correlation between gravity an the density of the fluid. Based on the density thehydrometer will float at a different angle. The graph below is an example on how the fermentation processcan be tracked.https://gravitymon.com/Note! In this version the R1 + R2 need...

Making a Retro Analog NTP Clock with Unihiker K10 - Arduino IDE Tutorial
Pavleski Oct 17,2025
 Some time ago I presented you a way to use standard Arduino libraries on the Unihiker k10 development board. Specifically, the project consisted of using the TFT-eSPI library and an integrated sensor with the result displayed on an analog meter. This time I will present you a project where I will test the Wi-Fi functionality as well as using the A and B buttons. And again I use a combination of "unihiker_k10.h" and other standard libraries. These buttons are connected to a pin on the ...
