“This is another one of my clock projects this time inspired by marble clocks. However, not wanting to replicate an existing design I created my own. Where most marble clocks contain a large number of marbles, this design is minimalist …
“MikroLeo project files (schematic, PCB, assembler, emulator/debugger, circuit simulation file, documentation, example of programs etc). MikroLeo is a 4-bit microcomputer developed mainly for educational purposes and distributed for free under open-source licenses. 4-bit Didactic Microcomputer The project is in …
“Suddenly, I got the idea to make a line follower robot without using a microcontroller. After that, I started researching this topic but can’t find any proper guidance. So I started simulating and building logic for each functionality, such …
“Vectron VGA Plus Text Mode simplifies displaying text with retro computers and microcontrollers by hiding the pixel-level details. Supply only row and column positions, and an ASCII character code, to write text to a 40x30 character VGA display. How It …
“Blinking RGB LEDs with 555s and a handful of 74-series logic The goal of this project is to display colorful patterns on a strip of WS2812 or SK6812 RGB LEDs (aka NeoPixels) without the help of an MCU. Addressable RGB …
“After various experiments and failed attempts to design a 7400-based computer, I came to a quite minimalistic 8-bit approach which is nevertheless pretty versatile and can utilize a surprisingly large amount of memory resources. The CPU core itself executes its …
“Hello and welcome back! Over the last few months, I am in the process of making a mechanical 7 segment display that uses PCB coils or electromagnets to actuate the segments. I had a lot of fun while learning new …
“32 bit RISC-V homemade In this article I will describe how I designed and made a functional 32 bit RISC-V CPU at home. Specifications: “Max” clock speed: 500 kHz Program memory: 512 kB RAM size: 512 kB VGA …
“Hello and welcome back to another Instructable. In the previous two Instructables, I have shown you how I created PCB coils in Kicad using a Python script, covered the basics of an H bridge, and showed you how I will …
“The MK1 CPU is composed of several modules, all connected trough a common 8-bit BUS, the status of each module is shown by dedicated LEDs. The clock module is designed to allow step-by-step execution; in automatic mode the clock speed …
