Some links on USB 2.0 and 3.0 galvanic isolators

Posted by jpluimers on 2025/02/27

Will likely need some of these in the future (be remember: USB 2.0 in Bulgaria and 3.0 in Germany price difference is about 10-fold) as galvanic isolation can reduce risks of gear blowing out a lot, for example when working with SDR (software-defined radio – often USB devices) and roof antennas:

  1. [WaybackSave/Archive] Mehdi on X: “What is a (USB) galvanic isolator, and when do you need one? It protects your expensive USB gadgets and also your host computer/laptop from noise, ground loop and power surges. An isolator basically sits between your computer and the target device, allowing full USB data …”
  2. [WaybackSave/Archive] Mehdi on X: “@oktayegi If you mean whether SDRs also can work via this isolator, then yes. Almost every device should work. Here’s a SDRPlay: …”
  3. [WaybackSave/Archive] Ondra OK1CDJ/OL0M🇨🇿/SV0SYH/J42T🇬🇷 on X: “@MehdiHacks Check this…”

  5. [WaybackSave/Archive] Archimago’s Musings: MEASUREMENTS: Intona 7055-C USB 3.0 SuperSpeed Isolator. And Darko & Lavorgna hear no difference with the Silent Angel ethernet switch. [Importance of open discussions.]

A long while ago, I participated in a Twitter thread that started with a translation of some important accessibility posts by Bianca Prins, then extended it to the concept to archivability:

[WayBack] Thread by @jpluimers: “I am going to first translate this, then extend this to archivability…. @jpluimers […]” #UXdesign #accessibility.

TL;DR

  1. make sure what you create is accessible
  2. ensure your (online) content is archivable
  3. help archiving content

Let’s go
