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.
