Rob Cai over on Instructables has created his personal model of the basic online game House Invaders utilizing an Arduino Nano. Nonetheless, in contrast to most different initiatives that might sometimes incorporate some type of LCD or OLED display screen, he selected to make use of a small black and white cathode ray tube (CRT) show recovered from an outdated video intercom system.

As his first step, Cai wanted to find the analog-only video enter on the salvaged display screen in addition to discover its rated provide voltage. From right here, he constructed a really minimalistic tiny arcade cupboard out of cardboard and used sizzling glue to hitch the panels collectively. However earlier than he might assemble something, Cai wrote his port of House Invaders by designing a number of sorts of 2D sprites and loading them into a number of arrays. Outputting a video sign was completed by way of the usage of the TVout library, which takes an array of pixels and writes them sequentially to the designated RCA video output pin, in addition to syncing every body with a secondary pin.

The controls for the sport are comprised of 5 buttons, with 4 on the left for transferring in a sure route, and the final one on the fitting for firing the participant’s laser upwards.
