DIY USB Servo-Guided Water Gun

Posted by timothy on from the seasonally-inappropriate dept.

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!"

    Are you saying this doesn't matter? Legions of Wicked Witches will be stopped by this new weapon. Fill it with holy water and we may survive the vampire hoard.

    This is all that matters.

    Can't you see... If one person builds one, then another will have to build one as well to defend themself. And, so, it escalates. Then comes the larger more powerful water gun. Then the mobile water gun. Then a brilliant but misguided developer creates an artificial intelligence. Building such a weapon will ultimately lead to IT armageddon. Think of the children!

    Fill it with holy water

    Kids today are not evil enough. Fill it with a mix of 3-methyl-1-butanethiol, 2-quinolinemethanethiol, or similar mercaptans (http://en.wikipedia.org/wiki/Skunk#Anal_scent_glands). Even using a dilute solution, your victim will have no friends for a week.

    It might even keep the kids off your lawn.

      It's like beer, only less so.

      Oh, so it's like American beer.

      My favorite old Aussie joke:

      Q. Why do Americans like their beer freezing cold?

      A. So you can tell it from piss.

    vampire hoard

    Are you suggesting there is someone out there stockpiling vampires in case of a vampire shortage?

    No. Absolutely not. Nobody is doing that.

    Completely unrelatedly, does anyone know if butchers will deliver blood directly to your basement? I'm never quite sure how to ask.
