How-To Guide for that 8-Bit “Rickrolling” Jingle #Prank
Late last year I blogged about that 8-bit rickrolling jingle coin cell prank that disrupted – and entertained! – some people at Cornell’s main campus. Finally stumbled upon the original project – hosted at hackaday.io – that includes not only some more build shots & confirmation the battery used was a CR2032, but also some interesting backstory and six simple steps for creating your own ATtiny85-based prank.
This is a small device that plays a short 8-bit tune (never gonna give you up) every 30-40 minutes. It takes advantage of the ATTiny85’s watchdog sleep/interrupt function to greatly reduce power consumption. If the device were to play a 5-second tune every 30-40 minutes, its battery could theoretically last for a year or more.
When pranking, it can be hard to find a good balance between humor, price, and not pissing people off too badly. How do you create something that will draw people’s attention while at the same time not causing a significant disruption? I decided I wanted to create a device to accomplish such a task.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
