Here is a neat home made cannon that uses the power of a shop-vac! “Make a simple cannon out of some tube and a vacuum cleaner. Play with the different types of tube and the length and diameter of the tube. Some will work better than others. Change the type of projectile, too. For some fun, try shooting marshmallows or mini marshmallows. There are endless possibilities with this project.”
Here is a cool project that you could build for about $20.00. Check out the full build details. “This project details a small & simple, but very powerful USB charger for your mp3 player, camera, cell phone, and any other gadget you can plug into a USB port to charge! The charger circuitry and 2 AA batteries fit into an Altoids gum tin, and will run your iPod for hours!
Great idea but I wonder how much practical use most of these will get. Well I guess lots of people want to see the wall behind my monitor. 🙂 If you are looking for other cool webcam things check out Phillip Torrone playing with the Logitech Quickcam Orbit MP. “Webcams finally got an upgrade with the SOIOS 55-Cam 360. It has a 0.35-megapixel sensor and FireWire support. With 360-degree, 270-degree,
This robot looks like an interesting project. If you can wait for a bit they will have some control boards available for sale soon. “Looks as if some enterprising hacker has built himself a robot that runs off a Nintendo DS handheld. The proposed specs are here: # 20 Digital Input/Output for multipurpose use. # Customizable with you own Motors and Sensors # Wireless programming and controling. # You can
Nice small gadget but I can see problems in the future when trying to deploy more horsepower to the desktop. It is a nice way to reclaim some space in a cramped cubical though. “The Jack PC may not turn out to be a jack-of-all-trades but still it stands apart with its breakthrough power consumption and miniature size. Jade Integration will roll out its skinny Jack next month that fits
Want to rule the world? Sprinkle some AI into some computers and give it a try. “My idea to expose this naive, simple-minded “brain” to the Internet and collect in this way an average internet personality was probably a little cruel, thousands and thousands of people were talking to the “kid” without any moderation, but the result that I got at the end was amazing. After being on-line for three
Ryan from Googlemarks brought us the NERF Rifle a short time ago. Well he is back at it, this time he has built a microcontroller based capacitive sensor. “Capacitive sensors have historically been regarded with fear and hostility among hobbyists. They’re notoriously flaky, unreliable, and difficult to design. Further, they traditionally fall in the “analog domain” which is something the casual microcontroller hobbyist can sometimes wince at. They usually require
