The IRF6648 is a 60V DirectFET power MOSFET that features a maximum on-state resistance of 7mV, which enables up to 30 percent lower device conduction losses compared to similar solutions. It is ideal for isolated dc-dc converters commonly used in telecommunications and networking systems. When it is used on the secondary side of a regulated 48V input, 12 output, 240W isolated converter, the power density of 72W/inches2 can be increased an additional 15 percent.

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.
