"Klappriger Blubberfetzen" "Nervendes Riesenungemach" "Windige Pupswindel"

Who doesn't like to be insulted? Schimpfolino is an evil gadget that always has a saying ready. Small, handy, power saving. And completely useless. You need a PCB and some parts listed below. It's easy to build and long lasting for everyday use. Insert battery, press the button and recieve your daily insult!

Huch, Englisch? Kann ich nicht. Schnell hier hin.

Schimpfolino is a random curse word generator with 12.288.000 possible combinations right now. That should be enough for a while. It's suitable for children (but still evil), maintenance-free and the battery lasts for years. And with the right case, it's an evil monster, like the Nokolino shaped case below! Just press the button, receive an insult, after eight seconds it turns off again. That's it. Evil. You can print the case in black! Black is an evil color. It is so evil. It is so evil that it hurts many people that are good!

What's new?
