RGB-Matrix-LED-Mario-Bros.-Clock
Super Mario is my childhood memory, when I saw JnthasMario Bros. Clock project, I immediately decided to make one
Solder-Reflow-Plate
PCB based SMD reflow plates
RGB-LED-Matrix-YouTube-Sub-Display
Displaying live YouTube subscriber count using an LED Matrix and and ESP8266 (Arduino)
Wash-Hands-timer
The sketch uses ESP8266(D1 Mini) as a 30 second countdown counter to remind that hand washing must last at least 20-30 seconds to prevent diseases and minimize the spread of diseases.

Joule-Thief
uses 3 pcs of PCB to make the Joule Thief look like a battery
NE555_Door_Lock_Timer
NE555 timer was launched in 1971 and has a history of 50 years. It is easy to use, stable and cheap, so it is still widely used, and its output in 2003 was 1 billion. Now I use NE555 to make timers. Most of the control parts of electronic door locks use this circuit. The timing method is very simple, 1.1 x RC, which is not very accurate compared with MCU, but it is very simple
PCB-Christmas-Tree
When Christmas is coming, what can an electronics lover do ? A PCB Christmas tree of course ! The idea here was to make a simple Blinky Board that drives 13 LEDs in a blinky sequence. LEDs are driven by astable multivibrator circuit.
