At that moment in time, the "Hobby" computer was cut of the edge technology:- compatible with both of the major Z80 operating systems of the time: CP/M and ZX Spectrum- single (256 x 192) and double (512 x 192) screen resolution- hardware switchable...
For now, updates are only being made to the github repository. https://github.com/edson-acordi/4bit-microcomputer Main Features: Implements a 4 bit CPU2k x 16 Program Memory (up to 4k)2k x 4 RAM (up to 4k)4 Output Ports (16 outputs)4 Input Ports (16...
This time I will show you how to make a sensitive Pulse Induction metal detector which is based on ARM STM32 microcontroller, which has significantly better features than Arduino and is also cheaper. It can detect metal coih at distance of 30cm,...

I plan on using this bus as the backplane for supporting R&D for my Kestrel Computer Project. Signals are as follows:SYSCON Signals.50MHZ. A 50MHz reference clock generated by the backplane. NOTE: This doesn't mean that the bus has to run at 50MHz; you're...
Control the classic General Instrument SP0256-AL2 speech chip and AY-3-8910 sound generator with a Raspberry Pi and this Python library. The SP0256-AL2 was originally available in the early 1980s in speech add-ons for the VIC-20, Atari 8-bit computers,...
Introduction Most electronic systems can be explained using this diagram. Systems consist of inputs that connect to the outside world, some form of processing or control and outputs to interact with the outside world. If the system needs...
This project is the continuation of this link Will we run out of water? There is water almost everywhere on earth but when we talk about fresh water, there is only 2.5% on our planet. Too many people on this planet do not have access to potable water....
After the Teensy 3.0 took me to the world of ARMs I quickly wanted to try different chips. While the Teensy boards and tools are great, they are limited to a very specific set of Freescale chips.ST sells ARM chips as well, so I got a nucleo board which...
Hardware ESP-32: The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESp32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes...
ESP_8_BIT is designed to run on the ESP32 within the Arduino IDE framework. Schematic is pretty simple: ----------- | | | 25 |------------------> video out | | | 18 |---/\/\/\/----|---> audio out | | 1k | | | --- | ESP32 | --- 10nf | | | | | v gnd |...

The work by others to port Arduino BASIC to the Smart Response-XE device was of interest, but I wanted a few enhancements to extend battery life (auto shutdown) and I wanted an easier way to do math on the console rather than typing "PRINT" everytime...
See info on the bottom of the description.Floppy disk drive (FDD) basic notes: Floppy disk is a magnetic medium. The data are stored on magetic disc, which is beeing rotated during the reading process. Speed of the rotation of disk is 5 times per second....
This project began with a request from the Incredible AquaGarden, who were busy building an aquaponics system as part of their project located next to the high school in Todmorden, UK. After researching the subject I advised that the available...
