• Update on weirdness

    Update on site issues: (1. replies now need a title *and* something in the message box, 2. certain links are causing strange pop-ups on Apple devices, and 3. Some folks can't type anything into the text box.) Basically, a series of unfortunate events set us back on testing. We'll get to it as soon as we can, and hopefully things can get fixed by this weekend if not before.  More info: https://jackpineradicals.com/boards/topic/site-problems-more-info/

    How to 3-D print your own sonic tractor beam

    Last year Asier Marzo, then a doctoral student at the Public University of Navarre, helped develop the first single-sided acoustic tractor beam—that is, the first realization of trapping and pulling an object using sound waves from only one direction. Now a research assistant at the University of Bristol, Marzo has lead a team that adapted the technology to be, for all intents and purposes, 3-D printable by anyone (with some assembly required, of course).

    In addition to a fully detailed how-to video that the group produced for the public, the results of the work developing this do-it-yourself, handheld acoustic tractor beam will appear this week as an open access paper in Applied Physics Letters.

    Sonic levitation is not new, and the use of sound waves to push around macroscopic objects, or create patterns in resting sand and flowing water, is scattered throughout YouTube and has been for years. This technology, however, is not simply sonic levitation, using sound to push objects around.

    Based on similar fundamental physics used to create optical traps for decades, these tractor beams are true to their name in that they pull objects, trapping small beads—and even insects—at their foci.
