MarekThings I've Built
Parallax Propeller based character terminal with retro keyboard.
This terminal is nothing original, but I found a use for my TI99/4A retro keyboard controller and with Propeller chip being so easy as an I/O controller, I am building a simple character terminal app. to control my MKHBC-8-Rx homebrew computer.
Arduino based aquarium feeder and light on/off scheduler.
Built with Arduino Nano, I2C LCD and 2 buttons, step motor, re-purposed battery operated fish tank feeder from Walmart and a relay for light on/off function. It is used on a real fish tank at my home for more than a year now.
Retro keyboard controller for micro-controller projects.
This is TI99/4A matrix keyboard with AT89S52 micro as a controller, serial interface similar to PS/2 (but simpler protocol) with Data and Clock lines. Easy to connect to Parallax Propeller or other micros.
MKHBC-8-Rx
This is still in progress. A MOS 6502 based 8-bit generic purpose microcomputer. Currently controlled with serial terminal, but being an expandable architecture I am adding peripherals as I go. Currently: RS-232, Banked RAM, RTC, MOS 6502 @2 MHz
LED Matrix Text Scrolling Message controller.
LED Matrix Text Messaging/Prompter controller. Based on AT89S52 (8051 compatible) built with chained LED matrix displays with individual controllers/shift registers, RS-232 as controlling interface and internal scripting engine and storage.

Thank you for liking my #Homemade Floating Point Interpreter for 6502. In order to comprehensively check the operation of the interpreter, I was able to run the Fourier transform program as some scale of operation, and I just added it to the article yesterday.
Marek, Just seen the arduino fish feeder etc. I too keep fish and shrimps, intended to build something like this for ages, just never got around to it.
Hi Marek,
Thanks for liking and following the Interak Z80 computer system.
