The origin of this project stems from a discussion about the RP2040 MCU (the first microcontroller from Raspberry Pi). At the time, we were discussing how to build a simple desktop/graphical user interface for the RP2040 MCU, and I casually mentioned, “Why not just run some old operating systems?” After saying that, I suddenly thought … Read more
MAKER: Shiura ／Translated by: Qu Wujin The fifth generation of the “Hollow Clock” is a comprehensive improvement and refinement based on previous versions. This clock features a thinner and cleaner ring design (only 7mm), complete with scale markings. Its appearance has almost no exposed screw heads (except for the center of the hands), making the … Read more
MAKER:DIY GUY Chris／Translated by: 趣无尽 The six faces of this colorful glowing cube are made up of a 5 X 5 WS2812 LED matrix, with each face connected through reserved soldering points. Each matrix plane is driven by an RP2040 chip, and theoretically, you can enlarge this cube and increase the number of cubes to … Read more
As many may know, Proteus is an EDA software that supports the simulation of microcontrollers. It has previously been used to simulate 51, AVR, PIC, MSP430, etc. Over time, it has gradually added support for Arduino, Raspberry Pi, and STM32. In the latest version (v8.17 sp4), Proteus has started to support MicroPython simulation. Below, I … Read more

In a previous article, we introduced a logic analyzer built using a serial port. Today, we will discuss a logic analyzer based on USB2.0+FPGA. Before we begin, let’s introduce a logic analyzer’s host software – sigrok. Without good host software, even if the hardware is built, the experience will not be good. sigrok Here is … Read more
