IoT For Makers

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> Make your own ClockClock   Now  let's build our own clockclock. Materials Here's what you need for this post: Raspberry Pi 4B(2GB Memory) : 1EA Electrodragon RGB Matrix HAT : 1EA P3 64X64 RGB LED Matrix : 3EA Hub75 cable : 3EA LED Power cable : 2EA 5V 20A Power supply : 1EA This is a picture of three 64X64 panels connected. Jumper settings for 1/32 scan mode 64X64 RGB LED matrix has 1/32 scan modes. So you must use E signal pin. Henner Zeller exp

So far I've covered a lot of blogs that mainly use Raspberry Pi + RGB Matrix HAT. The reason is that the display content can be handled freely. In particular, using the OpenCV and PIL modules in Python, various contents can be produced. The RGB LED Matrix is ​​so popular and widely used that there are many commercial products also. Users who unfamiliar with programming can also create their own content using specialized products for the RGB LED matrix, such as the HD-D15. My other blog has covered how to use this product. But I still love the combination using Raspberry Pi + RGB Matrix HAT. In previous posts, we have seen how to use up to 3 LED chains in one HAT. Normally, up to 12 LED Matrix can be connected in one daisy chain, but this value depends on the size of the LED Matrix, the performance of the Raspberry Pi, and the CPU resources required for real-time content creation. Assuming that up to 12 32 X 64 LED matrixes are connected per chain, it is theoretically possible to c
