Henkel Loctite has introduced a new VOC-free, no-clean liquid flux designed to reduce solder balling defects. Called Loctite Multicore MF300, this high activity flux targets tough-to-solder surfaces such as oxidized copper. Non-flammable and halide free, MF300 is a low residue flux that meets U.S. air quality legislation. This resin-free liquid flux can be used in conjunction with most commonly used surface preservative materials, and it passes stringent Bellcore electromigration and J-STD-004 surface insulation resistance tests without cleaning.

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.
