大量の超音波素子で広範囲型浮揚装置を作りました。

Here is a link to the previous work with an explanation of the principle.    • 超音波 物質浮揚装置を作ってみた！Fusion360と光造形3DプリンタPhoton...   (Japanese subtitles only) I made an ultrasonic levitation device before, but it was only effective in a small area. This time, I tried to make a larger one as a revenge. It seems that if made well, it can float water droplets and other objects. Unfortunately, no water droplets floated this time. Please enjoy the sight of a large number of foam beads floating and many ultrasonic elements lined up in a row. My technique is not very good, so I hope you will look at it with warm eyes. We are not planning to distribute 3D data or Arduino sketches on this channel. ＜tool and a material＞ [ANYCUBIC] Photon S　3D　printer [ELEGOO] Water washable UV Resin 405nm (White) [Riken Densen] Solder plated wire HLD-FSS 0.8N soft type [HiLetgo] Arduino Nano V3.0 ATmega328P CH340G 5V (Compatible) [HiLetgo] L298N Dual H-Bridge Motor Driver Controller Board [Amon] Amon Double Cord 0,2sq [GSI Creos Corporation] Mr. Finishing Surfacer 1500 Black [Daiso] Resin screen door [N/B] Aluminum U-shaped channel [N/B] Ultrasonic element 40kHz [N/B] Toggle switch [N/B] Wood ＜Music＞ 00:00 "Stellar Wind" by Unicorn Heads from YouTube audio library
