CH340C programmer [extra pins exposed]
M Feb 19,2023
I needed an CH340C programmer with some extra pins exposed (RST / CST) and because I didn't find one, I decided to build one. :)I wanted to keep it as small as possible, I chose to use 0603 resistors / capacitors/ LEDs. ME6211 is also a small footprint LDO. A small diode ensures reverse voltage protection.Hope you guys find this useful !If you’d like to say thanks, or buy me a coffee, a PayPal donation is always appreciated! ️

ESP12-F Relay Board
MakerIoT2020 Feb 12,2023
This is a general-use ESP12-F Relay board with Mains voltage on the Common of the Relay. An AC-to-DC power supply powers it.Most of the GPIOs are broken out.It features dedicated I2C headers ( 3v only), A DHT22 Header, optical isolation on the relay control line and additional 3v and 5v headers.CAUTION:The Relay contacts on this PCB are designed HOT ( Mains LINE voltage present on Common terminal). A maximum current of about 6A at 220v is assumed.

ESP32C3 WS8212 LED Control Over Node Red MQTT Broker
Useful Electronics Jan 30,2023
https://youtu.be/KY1ElV0qZDMIn this tutorial, a wirelessly controlled IoT lamp is built from scratch using ESP32-C3 MCU that is driving WS8212 addressable LED strip over RMT peripheral. The MCU is connected over MQTT to a broker that is running on a Raspberry pi. This will make exchanging command wirlessly with a smartphone connected to the same network possible. The browser based user interface side is handled by Node-Red dashboard, which is a very handy tool for IoT based applications.GitHub R...
