When Is Damascus Steel Not From Damascus?

If you grow up around a working blacksmith’s forge, there are a few subjects related to metalwork on which you’ll occasionally have a heated discussion. Probably the best known is the topic of wrought iron, a subject I’ve covered here in the past, and which comes from the name of a particular material being confused with a catch-all term of all blacksmith-made items. I’ve come to realise over recent years that there may be another term in general use which is a little jarring to metalwork pedants, so-called Damascus steel. Why the Syrian capital should pop up in this way is a fascinating story of medieval metalworking, which can easily consume many days of research.

Damascus? Where’s That?

The Damascus steel you’ll see in YouTube videos, TV shows, and elsewhere is a steel with complex bands and striations on its surface. It’s often used in knife blades, and it will usually have been chemically treated to enhance the appearance of the patterns. It’s a laminate material made by pattern welding layers of different steels together, and it will usually have been worked and folded many times to produce a huge number of very thin layers of those steels. Sometimes it’s not made from sheets or ingots of steel but from manufactured steel products such as chains, in an attempt to produce a result with more unusual patterns.

Is That A Record Player In Your Pocket Or…

If aliens visited the Earth, they might find our obsession with music hard to fathom. We have music in our homes, our cars, and our elevators. Musical performances draw huge crowds and create enormous fame for a select few musicians. These days, your music player of choice is probably the phone in your pocket. What our grandparents wouldn’t have done to have a pocket-sized music player. Wait…, it turns out they had them. [Rare Historical Photos] has pictures and other material related to the Mikiphone — a “pocket phonograph.” We don’t know how it sounded, but it is a fantastic piece of work visually. Actually, thanks to the [Stanford Archive of Recorded Sound], you can hear one of these rare machines playing in the video below. If only it were playing Toni Basil.

The device was made in the 1920s and had a decidedly strange tonearm. You wind it up with a gigantic key mechanism. There’s no electricity. A bakelite resonator became the speaker attached to the tone arm. The device was made in Switzerland by a company that started in music boxes. However, the design was the work of two brothers named Vadász.

Framework Motherboard Turned Cyberdeck

The beauty of a modular ecosystem lies in how it allows individuals to repurpose components in unconventional ways. This is precisely what [Ben Makes Everything] has achieved by using a Framework laptop’s motherboard and battery to create a slab-style cyberdeck. (Video, embedded below.)

The Framework motherboard presents an excellent choice for custom portable computer projects due to its relatively compact size and built-in modular I/O port options, all based on USB-C. Framework even released additional documentation to support this use-case. It’s significantly more powerful than the standard Raspberry PI, which is typically employed in similar projects. Ben chose a 2400 x 900 IPS display that can draw power and video through a single USB-C cable. For user input, he opted for an Apple keyboard and an optical trackball with a PS2 interface. He utilized a Arduino Pro Micro as a PS2-to-USB adaptor, using the remaining pins on the Arduino as a versatile interface for electronic projects.

The enclosure is crafted from machined aluminum plates with 3D printed spacers to secure all components. The screen can be tilted up to 45 degrees for more ergonomic desktop use. The Framework motherboard is equipped with four USB-C ports for peripheral devices; [Ben] allocated one for the display and another for a USB hub which connects the keyboard, Arduino, and external USB and HDMI connectors. The remaining USB-C ports are still available for original Framework expansion cards.

The completed project not only looks fantastic but may also be highly functional. It would have been a great entry in our recent Cyberdeck Challenge.
