Jadoo Power NABII (http://rbi.ims.ca/4915-544). Professional users who count on the availability and continued usage of key electronic tools have a fuel cell option. The NABII power system attaches to an end product instead of the battery and never needs to be removed. Instead, N-Stor energy cartridges, with hydrogen absorbed in a metal hydride solid, plug into the NABII and are replaced and refilled when depleted. Jadoo Power engineers developed a patented, digital interface to provide accurate state-of-fill and other fuel management data from the cartridges. The interface uses a low-power microcontroller to continuously update the user with power status to avoid downtime.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
