When repairing a section of pipe in an existing run, don't try to cement (solvent-weld) all the new couplings. Most drain ...

This report describes a series of experiments which were undertaken to determine the reduction in noise power radiated from heating radiators when flexible couplings are inserted in the feed pipes.

We suspect that [Les Wright] has pew-pewed his way through more than a few laser projects in his lab, including his latest experiments with fiber coupling of lasers. The video below is chock full ...
