Active-robots offer you the possibility to play with your own hi-tech robotic arm. The one I like it’s called The Lynx 5 and it can deliver fast, accurate, and repeatable movement. The robot features base rotation, shoulder, elbow and wrist motion, and a functional gripper. It’s made from ultra-tough laser-cut Lexan structural components, black anodized aluminum servo brackets, and custom injection molded components. The arm assembly has ball bearings for improved accuracy. The arm includes five Hitec HS-422 servo motors. One for the base, two for the shoulder, and one each for the elbow and wrist. An HS-81 is included for the gripper. The controlling of the arm is done by RIOS (Robotic arm Interactive Operating System) a Windows 95, 98, XP program. With RIOS, your robot can be taught sequences of motion via the mouse or joystick. The inverse kinematics engine makes positioning the arm effortless. This extremely powerful program uses external digital and analog inputs to affect the robot’s motion for closed loop projects. It’s available for about 450 $; for more information on this and other robot stuff you can visit they’re page at active-robots.com

Spicy Gadget Rolls has some great tips on extending the life of Lithium-Ion (Li-ion) batteries, the most common batteries these day’s. About battery storage: if you plan to store the battery for longer periods of time it’s recommended that the battery is 40 % charged and placed in the fridge (not freezer). If you store your batteries at 100 % charge level you will apply unnecessary stress that causes battery degradation. On the other hand if the charge level is too low the battery can become unusable quite fast due to battery self discharge. Read more about battery tips at Spicy Gadget Rolls
Although I don’t have the schematics for this one, from the video it seems all you need is a bunch of guys some beer and an old turbo-charger :).But I really recommend not to try this one at home, if you watch the movie you will see the gas’s turning the exhaust pipe glowing red, that look’s dangerous. If you need some information’s about home made jet engines or how to build one you can check this page
