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”

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:

Thread by @dosdude1 on Thread Reader App – upgrading storage from 512GB to 8TB on an M3 Max MacBook Pro

Posted by jpluimers on 2025/02/19

Cool thread: [Wayback/Archive] Thread by @dosdude1 on Thread Reader App – upgrading storage from 512GB to 8TB on an M3 Max MacBook Pro (images at the bottom of this blog post: they are large):

Just finished my most difficult Apple Silicon storage upgrade yet… 512GB to 8TB on an M3 Max MacBook Pro! This was especially difficult, as it required installing around 100 extra tiny components to use the second set of 4 NANDs…

Because I didn’t have schematics for this model, I had to painstakingly hand draw this diagram to locate the correct position of each component, which I derived based on a schematic for a similar model. Definitely took a long time!

If I need to have a Silicon Mac upgraded, this is one of the people to keep an eye on and when needed visit [Wayback/Archive] Technical Support – DosLab Electronics.

Dosdude1 has been active in this field of work for quite some time. A nice article on earlier work is [Wayback/Archive] Collin Mistr’s Open-Hardware 2.5″ IDE SSD Aims to Bring Speedy Solid-State Storage to Vintage PCs – Hackster.io.

Some notes on mini/micro Apple //e emulators

Posted by jpluimers on 2025/01/30

Retro computing is wildly popular, and with the rise of low cost single-board computers (SBCs for short), both Apple //e and ][+ emulators plus extension cards have proliferated,  based on Raspberry Pi (or even their RP2040 microcontroller based Pico), ESP32 or predecessor ESP8266 microcontrollers and others.

Some links for my archive:

Modifying your receiver/amplifier: Converting Phono Inputs to Line-Level

Posted by jpluimers on 2025/01/02

For my link archive: [Wayback/Archive.is] Converting Phono Inputs to Line-Level

It shows for some receiver models how to have the Phono input signals bypass the preamplifier (preamp) so they effectively become Line level inputs and there is no need for an extra devices that undoes RIAA equalisation.

If that fails, then you need something like the [Wayback/Archive.is] Line level to phono input converter diagram:

Pentium FDIV bug – 25 years ago; Ken Shirriff reverse engineerded the cause under a microsope

Posted by jpluimers on 2024/12/31

A small introduction is the Pentium FDIV bug – Wikipedia article which already has some of the highlights..

Ken Shirriff however went all the way in, and used a microscope to focus in on to the actual cause.

He wrote two Mastodon threads on it watching (most recent first, with a link to his blog post) making a good year’s end read:

And there is of course this, that predated his microscope work [Wayback/Archive] Ken Shirriff: “I recently saw an amazing Navajo rug…” – OldBytes Space – Mastodon Read the rest of this entry »

SCANSNAP iX100 SCANNER REPAIR MANUAL – PFU Ricoh Store

Posted by jpluimers on 2024/11/28

Ordered because all of a sudden, my scanner would only charge over USB, but not connect to any computer any more over USB (likekly because the Micro-USB connector on the mainboard was broken which is odd after just a few 100 inserts which is odd as it should last 10k+ cycles according to USB hardware – Wikipedia) [WaybackSave/Archive] SCANSNAP iX100 SCANNER REPAIR MANUAL – PFU Ricoh Store.

It costs only USB 0.00, so I hope they will send it outside of the USA.

When ordering, you have to agree with these:

When I don’t receive the manual, hopefully the translated version of this video will be of help: [WaybackSave/Archive] Reparación Scanner Fujitsu ScanSnap – Puerto De Carga Micro USB – YouTube -> Fujitsu ScanSnap Scanner Repair – Micro USB Charging Port – YouTube.

Como me pasa muchas veces esto grabe este video. Me piden que repare algo que ya intentaron reparar de la manera incorrecta.

->

As this happens to me many times, I recorded this video. I am asked to repair something that they already tried to repair incorrectly.

Queries:
