If you are fortunate enough to have already purchased your own Digispark board you can skip this build and move on to the main build.

You’ll also need a breadboard and prototyping hardware. The Fundamental Build: The Prototype Parts Required: This bootloader allows the device to emulate USB hardware and thus act like a keyboard. The Digispark is, however, little more than an ATtiny85 microcontroller with a funky bootloader called Micronucleus, which is another open-source project. You can buy the Digispark board online from various vendors, including the Australian Distributor: What separates the Digispark from other Arduino based development boards is its onboard USB capabilities. They ran a very successful Kickstarter to develop and produce the Digispark, which is a completely open-source Arduino based development platform. The heart of this project is a USB development board called the Digispark from a company called Digistump. I will provide as many examples of different functions as possible, which you can then adapt for your own custom pranks.

As all hardware is essentially handled by the single Digispark device, however, things will be more in-depth when it comes to the software and coding. You can use them to have a little bit of harmless fun with like-minded friends.ĭue to the simplistic nature of this project, it is fairly light on the hardware side. The good news for us pranksters is that you don’t need to use them purely in a productive sense. Having a rubber ducky means you don’t need to babysit the process and thus you’re free to do other tasks.

For example, I have used them in the past to install Windows on new computer systems, all with the same network configuration settings, via Telnet. THE BROAD OVERVIEWĪ regular USB rubber ducky is basically a programmable keyboard emulation device that allows a person to rapidly enter keystrokes to quickly perform a task on a PC, which they usually need to do many times. If you know someone who has a sense of humour and doesn’t shy away from a bit of light pranking this may be something you want to build. Their font randomly changes size, the caps lock key randomly toggles, or YouTube suddenly opens to a pop song from the late 1980’s from a guy called Rick, singing about never giving you up. Imagine your friend or colleague sitting at their desk typing out an important email or writing a report for an assignment, only to have weird and crazy things appear at random intervals. This project is for those of you who are known for being the practical joker in the home or office.
