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

[Wayback/Archive] Electronic Basics by GreatScott! – YouTube
At the time of writing these were some 60 videos each 5-15 minutes long in reversed order (#1 at the bottom, #61 at the top).
This means it is about 10 hours of watching time well worth it.

When at look at a local Amazon site, they have plenty of stuff: [Wayback/Archive] Amazon.de : 10 inch rack
2023 example via [Wayback/Archive] Ikea Eket DIY 10″ Rack (UK) [build showcase] · Issue #22 · geerlingguy/mini-rack · GitHub:
Via [WaybackSave/Archive] Jeff Geerling on X: “Everyone in #Homelab knows about the DIY 19″ IKEA LACK rack… but did you know IKEA makes the perfect mini rack furniture, too? Presenting stirkage’s Eket rack! …”
[Wayback/Archive] Tweet JSON (image on the right).
That tweet and [WaybackSave/Archive] Jeff Geerling on X: “Indeed… there’s gotta be some nerd at @IKEA who’s ensuring certain furniture fits standard sized rackmount gear, right?” (image below via [Wayback/Archive] Tweet JSON) have some interesting replies, making the list of usable IKEA products at least this:

[Wayback/Archive] How TINY Can I go? The BEST Power Board is here! – YouTube – GreatScott!
I will try to remake an AliExpress PCB. It is a very handy voltage converter that can take a varying battery voltage and convert it into 3.3V or 5V while only requiring very little current (25uA) on the input. Sounds awesome, but the board is way too huge. That is why I try to push the size limits in this video to the minimum.

From a few years back when Lightning debugging cables were either expensive, hard or not to get at all: [Wayback/Archive] DEF CON 30 – stacksmashing – The Hitchhacker’s Guide to iPhone Lightning and JTAG Hacking – YouTube.
Basically it is a Raspberry Pi Zero with adapted firmware connected to half a lightning extension cable.
A textual description (I wish it was linked from the above video) is at [Wayback/Archive] stacksmashing – The hitchhacker’s guide to iPhone Lightning & JTAG hacking – DEF CON Forums, which in turn refers to:

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:

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:
