#ultrasonic — Public Fediverse posts

I help a technically versatile friend to run a small workshop to built a #pippyg #batdrecorder. It automatically records the #ultrasonic sounds of #bats. Any experience out there on the building process or the quality of the finalized device (if assembled correctly)?

Some #Homelab success today:

Finally finished a rough de-duping of my old music files, enough to justify setting up #Navidrome for streaming from my home server.

So I did! Even got it up and running on my phone and my wife's phone. Trying out #Amperfy on my wife's iOS and #Ultrasonic on my GrapheneOS.

So far so smooth!

I wish there was a way for my wife to build her own library out of our super large library (that is mostly my files)... but we can probably find a work around for that later.

Review: NeoBlade Wireless Ultrasonic Cutter

https://www.seerofsouls.com/review-neoblade-wireless-ultrasonic-cutter/

Thanks to the folks over at HOZO Design for sending over their newest product for me to review, the NeoBlade Wireless Ultrasonic Cutter. Previously they had sent me their NeoRuler and their M-Cube Laser Level which are two really great products.

Estonia based company stops shipment of product to the U.S.. The company stops short of saying they can't afford the #tariffs . Instead they claim, "inconsistencies in how import tariffs are applied." Based on other reports, there's probably some truth to that. After all, Trump changes the amount of penalty he's placing on other countries almost every day. #vinyl #ultrasonic #music

Oh man, I have this #Xiaomi #T700 #smart #ultrasonic #toothbrush for more than a year I guess and I never scored higher than 91 points. I did notice that at some points it stops oscillating for a split second but never really thought why.

This week I stumbled upon a note that you should brush your teeth in quadrants. Boom 🤯. Turns out it stopped after 30 seconds so that I knew that it’s time to switch to the e next quadrant. Today I scored 95 and the brush displayed a crown 👑 😂

🔊 One exploit I love to demo: nUHF / #ultrasonic tracking. Digital mics can pick up sound not audible to humans embedded in ads, apps, or even lightbulbs (yes, really). You couldn't hear it, but your machine did.
