Pseudonymous maker “mars91” has constructed a pocket-friendly handheld console, designed to run the basic sport of Snake or the once-viral Flappy Chicken on an RGB LED matrix — beneath the management of a Microchip ATtiny1616 microcontroller.
“A pocket-sized gamer that makes use of an 8×8 RGB pixel matrix to play Snake, Flappy Chicken, and another retro video games you may design,” mars91 explains of their creation. “I believe vivid RGB LEDs look nice, and needed to create one thing that showcases them. I began with the basic sport of Snake and ended up with each Snake and Flappy Chicken, all programmed with minimal parts.”
The custom-built circuit board — which incorporates the supply code for Snake on its silkscreen layer — is constructed round a Microchip ATtiny1616 microcontroller, linked to 5 buttons: 4 path buttons and a fifth that can be utilized to change between the 2 video games loaded within the firmware, or extra should you add your individual. There are pads for an Adafruit DotStar 8×8 RGB LED matrix, an influence swap, and a CR123A battery holder on the rear — together with connections for an UPDI programmer, the board missing USB connectivity for programming.
“The LED matrix asks for an electrolytic capacitor as a result of potential fast and excessive present attracts when many LEDs are turned on directly,” mars91 explains of 1 specific design quirk. “This sport solely lights up a number of LEDs at a time (except you are good at Snake), so I selected to not use a capacitor. I’ve examined this board for hours and mine works with out them.”
