We invited [Jay Doscher] to give us a view into his process designing 3D printed parts for the impressive array of cyberdecks we’ve covered since 2019.

[Jay] got his start as a maker through woodworking in high school, getting satisfaction from bringing something from idea to reality. After a more recent class in blacksmithing and ax-making showed him what he could do when really focused, his hardware hacking really took off and his line of cyberdecks and other portable computers was born.

If you’ve heard of Tinkercad, you probably think it’s just for kids. While designed as an educational tool, [Jay] found that Autodesk’s younger sibling to the professionally powered (and priced) Fusion 360 had everything needed for making cyberdecks. If you’re willing to work around a few limitations, at the low-low price of free, Tinkercad might be right for you too.

What limitations? To start, Tinkercad is only available in a browser and online. There’s also no guarantee that it will remain free, but [Jay] notes that with its educational focus that is likely to remain the case. There is no library of common components to import while modeling. And, when your model is complete the options for exporting are limited to 2D SVGs and 3D STL, OBJ, and gaming-focused GBL formats. [Jay] has converted those to other formats for laser cutting and the STEP file a machine shop is expecting but admits that it’s something that adds complexity and is an annoyance.

In the talk, [Jay] discusses moving from his initial “cringy” explorations with Tinkercad, to his first cyberdeck, a little history on that term, and the evolution of his craft. It’s mostly a hands-on demo of how to work with Tinkercad, full of tips and tricks for the software itself and implications for 3D printing yourself, assembly, and machining by others.

While quite limited, Tinkercad still allows for boolean operations to join two volumes or the subtraction of one from another. [Jay] does a wonderful job of unpeeling the layers of operations, showing how combinations of “solids” and “holes” generated a complex assembly with pockets, stepped holes for fasteners, and multiple aligned parts for his next cyberdeck. Even if you already have a favorite CAD tool, another approach could expand your mind just like writing software in Strange Programming Languages can.

Before there was the Internet, there were a lot of would-be Internets. Compuserve comes to mind, as do Prodigy, GEnie, Delphi, and the innumerable BBS systems that were once gateways to worlds beyond our CRT monitors and 300 baud Hayes Supermodems.

Service providers varied by region, of course. The French postal and telephone service rolled out their service, Médium interactif par numérisation d’information téléphonique, in 1978. Mercifully and memorably shortened to Minitel, the service was originally intended primarily as an online telephone directory, and later expanded to include other services. [Kevin Driscoll] and [Julien Mailland] recently resurrected a Minitel terminal, a Videotex terminal that was the gateway to the service. The terminal they used, a model 1B, is a stylish machine with a monochrome CRT display and compact “AZERTY” keyboard. [Kevin] and [Julien] built a Videotex server for it using an Uno and a logic-level converter to keep the two talking. Using the hardware, they’ve developed a Twitter client, a webcam display, and dumb Linux terminal.

[Julien] and [Kevin] previously authored a great history of Minitel that’s worth a read. And we’ve seen a few Minitel hacks before, including converting one to USB for use as a Raspberry Pi terminal.
