A replacement PCB for Hori Pad Mini controllers supporting software calibration & Hall Effect sensors.

This is the development kit using the Esp32-Wrover microcontroller that I designed.

This is a twin delta loop antenna designed for the 1200MHz band for HAM radio practitioners. It can be used by soldering an SMA connector.

A game console that fits in the palm of your hand, with 3 buttons, 9 pixels, and 5 games.

In this tutorial, I am going to show you guys how to design this "Transformers PCB Badge" and how to solder the components to it.

The development board uses the RP2040 microcontroller, you can order your own pcb as well as components to solder yourself.

An open-source ecosystem for putting Raspberry Pi on the IoT edge

R4TKN Deauther transforms the Ai-Thinker BW16 (RTL8720DN) into a dual-band 2.4/5 GHz Wi-Fi security lab tool, simulating disconnection events to audit and harden networks—featuring a portable, TFT-driven UI for authorized testing only.

In this tutorial I am going to create a chaser circuit that can drive 20 or more LEDs using 555 timer IC and CD4017 decade counter.

Introducing a cost-effective flight controller PCB designed for budget-conscious drone enthusiasts and educators: powered by the STM32F405RGT6, this board integrates the MPU6050 IMU and BMP280 barometer for stable flight in basic quadcopters and fixed-wing UAVs, offering a reliable, easy-to-integrate solution perfect for learning and experimentation, with open-source compatibility and simplified design.
