“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 …
“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 …
“This is a homemade 7-bit SAR ADC using discrete components for principle study. The following is an introduction to a Successive Approximation Register Analog to Digital Converter (SAR ADC) that I made myself for principle study, and observing the conversion …
“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 …
“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 …
“This project is 7400 series logic ICs based clock. It keeps time solely based on discrete logic ICs and a stable clock source. For the display LEDs, I am using common anode 7 segment displays. This variant is 0.56 …
“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 …
“Vectron Handheld is a retro handheld gaming console based on the 6502 CPU. It has five input buttons (up, down, left, right, fire) and a 1.8” 128x160 18-bit color TFT LCD display. I have developed an implementation of Pong …
“NTP synchronized dot matrix clock showing temperatures and humidity.. Optionally the time source can be GPS. That is what some readers may think, what? Another dot matrix clock? In order to combine inside/outside thermometers with a nice and precise …
“After 20+ years of programming, I wanted to get some understanding of the electronics that make my career possible. I had built the basic individual logic gates with transistors on a breadboard, but to build anything meaningful I needed loads …
“This project is my simple Arduino compatible controller that has embedded Ethernet, and the capacity to drive some extra I/O lines for projects, such as a Remote thermometer, a Remotely accessible Fridge controller, and a Remote Humidity sensor. I …
