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

Simple Cute Dog Keychain with LED's

CH591D module- BLE5.4, USBC, RTC, ws2812b

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.

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.

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.

BenchVolt PD is an open-source, USB Power Delivery-based bench power supply capable of delivering up to 100 W through multiple DC-DC converters and LDO channels. It provides adjustable and programmable outputs(waveform capable), current monitoring, and real-time voltage/current display — all powered directly from a USB-C PD adapter.

Open Hardware and Firmware for a Hall-sensor-based 6-step BLDC motor controller using PIC18F Microcontroller.

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