[Wayback/Archive] peter purgathofer: “today i gave a talk, where the…” – 🌱 hci.social
today i gave a talk, where the setup was that i had to share my presentation over zoom, but i didn’t have a second screen. this usually meant that i have to forgo seeing my presenters’ notes because my notebook’s screen would be the shared presentation screen.
i recently found a little HDMI-fob that fakes a second screen; i can now see my presenters’ notes on the built-in screen, while the presentation is on a hallucinated second screen.
simple and effective.

Wonder how well it does with a combo of APC and Victron UPS systems.

It was pretty hard to find any model/part-number information on optional video boards for the Dell 3060/5060/7060 Micro series (also known as Regulatory Model D10U and Regulatory Type D10U003).
These models by default had HDMI (version 1.4) and full-size DisplayPort (version 1.2) and additionally could ship with these configurations:
There was (seems not available any more) a serial port (:
Further below are some links I found, but first a ink to a good post on differences between 3060/5060/5070:

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).

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:
