Adam and Jamie from Mythbusters built a huge paintball gun that can shoot 1100 paintballs in an blink of an eye. When the balls crash on the canvas you can see a picture of the Mona Lisa. This was an attraction at an Nvidia event, I wonder how much the unit cost! I guess when you have a huge budget your mind can do wild. Via: Hack a Day
 We have seen lots of automated sentry guns over the past year but this Autonomous Paintball Sentry Gun by Zero Op is the first I have seen for sale. For about $3000 you could buy the system and have enough left over to buy some paintballs. If you need to guard a large open area this may be just the ticket.

Looking for a personal submarine? Have a look at the Triton 1000. Honestly what drew me to it wasn’t the actual sub but rather the design, I think this would make a great scaled down model. "The Triton 1000 is U.S. Submarines’ latest design and represents an advanced, light weight minimum volume 2-person configuration engineered specifically for deployment from megayachts. With an overall height of 1.8 meters and an
A recent study by Kevin Fu, an associate professor at the University of Massachusetts at Amherst and director of the Medical Device Security Center, has uncovered a weakness in some pacemakers. It turns out that pacemakers communicate with a computer during initial configuration. This wireless communication channel is not encrypted and provides test functions that can turn off the device! The research team has developed a countermeasure which allows
I have seen a few of these waterfall displays before. But this water display has some very impressive patterns. I think if the room lights were dimmer the effect would be enhanced. These systems use many solenoids which are computer controlled to drip at the right time. Via: HackNMod
Trossen Robotics just completed their latest project contest, the Xr-B3 didn’t win but it is a very cool creation! "He is powered by an AVR ATMEGA324P micro controller on a custom board that I made. He is using an XBEE module to communicate with my PC (and eventually with other robots). Onboard sensory includes: 2 Sharp IR sensors (for wall following and obstacle detection), an SRF-05 sonar sensor and
Kids don’t try this one at home! This DIY Flamethrower by Everett Bradford looks dangerous but it does a good job of imitating the fire throwing capability of Pyro from X-Men. "The Pyro System is my final project for a mechanisms class in the spring of 2008. It gives me the power that the X-Men character Pyro has"
