A storage history thread by @Foone: from USB Floppy drive back to Shugart via UFI/ATAPI/SCSI and everything in between
Posted by jpluimers on 2021/08/19
Quite some interesting bits in [WayBack] Thread by @Foone: “So if you want to use a USB floppy drive, you use a USB protocol called the UFI: Uniform Floppy Interface. What’s UFI? A way to embed ATAPI […]”
Via [WayBack] Kristian Köhntopp on Twitter: “PC Hard drive and floppy disk interfaces, and the people and companies that made them.”

Threaded Inserts in 3D Prints – How strong are they? – YouTube
Posted by jpluimers on 2021/03/17
They are much stronger than plastic threads, no matter how you create the plastic threads.
To make them even stronger, add shell thickness to the thread locations, either globally or by using modifier meshes. Modifier meshes work way better in Cura than in Slic3r.

Electronics-Salon DIN Rail Mount +/-20Amp AC/DC Current Sensor Module, based on ACS712: Amazon.com: Industrial & Scientific
Posted by jpluimers on 2020/12/24
For my link archive (this DIN rail device allow sensing current used by a circuit; models for 5A/20A/30A).
- DE [Archive.is/WayBack] Electronics-Salon DIN-Schienen +/-20amp AC/DC Current Sensor-Modul, basierend auf ACS712: Amazon.de: Gewerbe, Industrie & Wissenschaft
- COM [Archive.is/WayBack] Electronics-Salon DIN Rail Mount +/-20Amp AC/DC Current Sensor Module, based on ACS712: Amazon.com: Industrial & Scientific
Thanks Matthijs ter Woord for pointing me to this.
Schematics show it uses an LM317 linear voltage regulator (to get 5V out of a 8V-35V range) next to the ACS712 current sensor (based on the [WayBack] Hall effect) available in 5A, 20A and 30A varieties.
