Hello there,

Isn't the Annyoing PCB annoying enough for you?
Here, take the case and let your "victims" open the case first...

If you're expecting a design masterpiece, I'm sorry to disappoint you.
The simplest design with no frills.

I've made a small opening in the side so that you can turn the PCB on and off - I think the annoyed victims won't find the little switch...

Before the top layer is printed, the printer pauses so that you can insert the Annoying PCB.
