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
