For my link archive: swSIM and swICC by Tomasz Lisowski, two open source repositories to enable SIM card emulation

I wonder how this evolved, as the links are from fall 2022:

GitHub – PiSCSI/piscsi: PiSCSI allows a Raspberry Pi to function as emulated SCSI devices (hard disk, CD-ROM, and others) for vintage SCSI-based computers and devices. This is a fork of the RaSCSI project by GIMONS.

Cool (and available both for regular Raspberry Pi and Raspberry Pi Zero):

[Wayback/Archive] GitHub – PiSCSI/piscsi: PiSCSI allows a Raspberry Pi to function as emulated SCSI devices (hard disk, CD-ROM, and others) for vintage SCSI-based computers and devices. This is a fork of the RaSCSI project by GIMONS.

I wonder how it compares feature wise and performance wise to [Wayback/Archive] BlueSCSI (which is Raspberry Pi Pico based, see [Wayback/Archive] index – BlueSCSI v2 Documentation, and now has a [Wayback/Archive] BlueSCSI Wi-Fi Desk Accessory – joshua stein which is open source at [Wayback/Archive] jcs/wifi_da – BlueSCSI Wi-Fi Desk Accessory for classic Mac OS – AmendHub and important to for instance [Wayback/Archive] Adding Wi-Fi to the Macintosh Portable – joshua stein).

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…”
  4. [WaybackSave/Archive] ⚡bacteriophage⚡ on X: “@ok1cdj @MehdiHacks nah, based on ADUM4160 so only 12Mbps data rate. ADUM4165 with 480 Mbps is preferable”
  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.]

Thread by @mariusheier on Thread Reader App – USB-A to USB-C. A @cursedconnector ? Or genius?

Posted by jpluimers on 2025/02/20

Cool:  [Wayback/Archive] Thread by @mariusheier on Thread Reader App – USB-A to USB-C. A @cursedconnector ? Or genius?

Image on the right is larger on [Wayback/Archive] Gdn-fwFW4AAao2D.jpg (964×772)

I think it is genius, as it is way shorter than what I found on sites like Amazon, ebay, Aliexpress and others.

For now I am using ones from Amazon that are a tad bit too long (thereby putting too much stress on the USB C output of my laptop), but they are charging only (no video capability): [Wayback/Archive] USB C Female to USB Male Adapter Pack of 3, Type A Power Supply Charger Cable Adapter for iPhone 11 12 13 Pro Max, SE, iPad Mini 6 Air 4 5, Apple Watch iWatch 7, Samsung Galaxy S20 S21 S22 Plus Ultra FE: Amazon.de: Computer & Accessories (image below)

The one Marius posted about is also charging only, but shorter: [Wayback/Archive] 1-10PCS Type-C 3.1 Female to Double-sided USB Am Male Connector 2.0 Charging Version Adapter with PCB Board Inside – AliExpress

Compare with the picture of the Amazon one:
