Virtual Tetris

Introduction The idea to my mechanically scanned game system came from Bob Blick's mechanically scanned clock, so I thought that I also had to implement a clock on my virtual game system. The clock can simulate both a digital and an analog clock. Due to that the resolution of the clock is only 24x16 pixels, it is hard to show the time in both cases. In the case of the digital clock, scrolling the time over ...

Virtual Tetris

Introduction Tetris is a very simple, but elegant game. Blocks of four bricks each are falling down in a play field, and the player can rotate and move the block sideways. When the block hits ground or another block below, it stays there. If one line of bricks is full, then that line is removed. As the game is running, the falling speed increases. The goal of the game is to keep playing as long as possible, ...

Virtual Pong.

Introduction The game Pong was the world's first video game in the early 70's, it is a tennis lookalike game where a ball is played with two rackets, which are moved up and down by each player. The ball can bounce at the floor and the ceiling. This version is implemented with the virtual game system It was the first game I made for the system. Features Some special features of the game is that it is possibl ...

Virtual Game System – A game console with a mechanically scanned display.

Introduction If you move a bright light fast by the eyes, it will leave a line behind because the human brain and eyes are slow to interpret fast changes in light intensity, leaving an afterglow. If a row of LED’s is moved sideways while the LED’s intensity is changed, an image will shortly visualize in the air where the LED’s are moved. If this is done several times, for example if the LED’s are mounted on ...

SX-Pong

After making the tetris game, it was very easy to make a Pong game. The game Pong was the world's first video game in the early 70’s; this is a modern version of it, made with a little bit less hardware than the original version. In my version, the video signal is generated in software. The video generating hardware is a 5-bit DA converter built with a few resistors. Usually the video signal is generated in ...

SX-Tetris

The first game I made in color using SX-chips was Tetris. Tetris is an old Russian computer game where you should try to fit in block into a play-field, quite simple but really fun. All blocks are built from four bricks (the name Tetris is derived from the ancient greek word for four: "tetra"), there are seven combinations of the four bricks as seen here to the left. This version is using my SX Video Game S ...

SX Game System

This page describes a SX28-based color video game system I made during year 2002. Now, beginning of 2007, almost five years after I made the first design I've updated the layout of the PCB and added a version of the PCB that has built-in gamepads and I also have made it possible to buy PCBs, preprogrammed chips, color carrier oscillators and of course complete kits from me in my web shop. Since all games us ...

PIC-Tetris

Introduction I have made the game Tetris using a PIC16F84 running @ 12MHz. Tetris is an old Russian computer game where you should try to fit in block into a play-field, quite simple but really fun. All blocks are built from four bricks (the name Tetris is derived from the ancient greek word for four: "tetra"), there are seven combinations of the four bricks as seen here to the left. This version is using m ...

Building the PIC16F84 based game system

This text describes how to build my PIC16F84 based game system, before you start you should read through the whole text one time. Note that many components are sensitive to too much heat and will get damaged if you heat them too much when soldering. The drawn placement images show components to mount in each step in black and the components mounted in previous steps in gray. When soldering the components on ...

PIC Game System

This page describes a PIC16F84-based video game system I made and first published back in the beginning of 1998. Now, beginning of 2007, nine years later I've updated the layout of the PCB and also updated the source code to also be able to run on a PIC16F628A as Microchip is phasing out the 16F84 and it will soon not be able to be bought. The final new "feature" is that you now also can buy PCBs, preprogra ...
