The H-cell is a unique integration “upgrade” kit for electric hobby R/C cars, designed as a drop in unit that can fit inside widely available Tamiya TT-01 type chassis. The H-cell system designed by Horizon Fuel Cell Technologies includes a 30W air-cooled, air-breathing and self-humidified PEM fuel cell stack with integrated bright blue light-emitting fans and a sleek aluminum casing.
The integration kit also includes electronic controls, a miniature pressure regulator and three 10L metal hydride canisters in a hydrogen storage “rack”. At maximum power output and with a single charge, the H-cell can run the car at 35 km/h for over 1 hour, as opposed to just 15 minutes with the conventional Nimh battery.
The price of the Hydrogen RC car kit is $1500.
A PicoCricket is a tiny computer that can make things spin, light up, and play music. You can plug lights, motors, sensors, and other devices into a PicoCricket, then program them to react, interact, and communicate.
For example, you can make a cat and program it to purr when someone pets it. Or you can make a birthday cake and program it to play a song when someone blows out the candles.
The PicoCricket Kit is similar to the LEGO MINDSTORMS robotics kits. MINDSTORMS is designed especially for making robots, while the PicoCricket Kit is designed for making artistic creations with lights, sound, music, and motion.
The price of a single PicoCricket Kit is $250.
