This project is in the idea stage.
Next step would be to test if the new schematic could work before ordering the first PCB.
I made a huge LED clock with pieces of LED strip in 2013 using an ATmega328 and DS3231 RTC. It has been running great and keeping time just fine. Lets break it by upgrading it.
This project will upgrade the spagetti old circuit to an internet connected LED strip clock neatly on a PCB. The brains will be a Wemos D1 mini and will use NTP to synchronize the time.
The circuit recycles the same TPIC6B595 power shift registers and changes the ATmega328 for a ESP8266 and the DS3231 for a DS3231MZ. A 74HCT244 buffer translates between the 3.3V outputs of the ESP8266 and the 5V inputs of the shift register. The original circuit has a rotary encoder to set the light intensity and the current time. The new circuit will only use the rotary encoder to set the light intensity.

My Kicad library is used in this project.
