DIY USB Servo-Guided Water Gun
An anonymous reader writes "What better way is there to learn something than by making your own DIY gadget? Here's a new video showing how to use a common hobby servo, in conjunction with a small water pump, to create a USB controlled water gun! You can use your keyboard to aim and fire at an unsuspecting passerby. Both fun and educational, this project looks like a great DIY weekend project for any IT guy, wanting to make sure people think twice before asking a stupid question!"
What is this? News for nerds? Stuff that matters?
Think of the children!
Can't. The judge says I've got to atleast think at a barely legal capacity.
