Do you know TetrisClock? TetrisClock is a WiFi clock made of falling tetris blocks. Runs on an ESP32 with an RGB LED Matrix. <TetrisClock on the RGB LED Matrix by Brian Lough> I'm a big fan of RGB LED matrix and I wrote many posts about RGB LED Matrix in my blog . I like to display the screen using OpenCV on the Raspberry Pi to the RGB LED Matrix. However, the TetrisClock shown in the figure above works on the Arduino family of ESP32 MCUs. I also posted a post implementing TetrisClock on ESP32 at https://iot-for-maker.blogspot.com/2020/04/led-9-rgb-led-matrix-drive-with-esp-32.html . But I wanted to implement this beautiful clock in Raspberry Pi, so I googled hard, but couldn't find any good examples. Eventually, I decided to analyze the code written in C language and implement it in Python and OpenCV. In the picture above, it consists of four large numbers indicating hours, minutes and small letters indicating morning(AM) and afternoon(PM). Original code analysis Number ...

ClockClock24 Do you know ClockClock24? ClockClock24 is kinetic art by Humans since 1982. Twenty-four analog clocks form a large digital clock. Clever arrangement of the clock hands transforms the analog clocks into seven-segment displays. <captured from https://www.humanssince1982.com/clockclock24>  Here's an introduction video. This fantastic clock can also be purchased directly online Moma Design Store . But the price is not easy. The price is surprisingly 5,400 $ <Moma online store> I came across a page a few days ago that implemented Clock Clock 24 on the Raspberry Pi. The url is https://manu.ninja/clock-clock-24-on-a-raspberry-pi-using-web-technologies . This work is implemented on the web using Javascript. I wanted to implement this work in Python using OpenCV. ClockClock24 development using OpenCV ClockClock24 uses a total of 24 clocks of 3(H) X 8(W). And 2X8 clocks display one of the numbers from 0 to 9. The numbers 0...
