Could Camera Hardware Be The Physical Equivalent To USB-C?

[Mansour] presents an interesting idea in his essay A Common Thread — just as USB-C has become the “One Connector To Rule Them All” in the world of electronics, so too should his projects have a unified physical connection layer. A common thread, if you will.

Specifically, the 1/4″-20 UNC connector that was already on all his camera equipment. Unifying his stuff around that connector wasn’t a bolt from the blue brainwave. By the sounds of it, the idea evolved over time and only became intentional after he’d already started using it.

There’s something to be said for it, though. One thing is the convenience of knowing your various bits and bobs are going to fit together like they were made with LEGO. Another is taking away a whole set of decisions in the design process: it’s going to have a 1/4″-20 UNC fitting, so [Mansour] needs only decide if its going to be tapped into the material or if he’s using an inset or captive bolt.

It isn’t like a 1/4″ bolt is going to introduce a weak point in most things we build — with good hardware it can take a ton or more. On the other hand it’s not exactly resilient to torque, but [Mansour]’s camera bag had the answer to that, too: spring loaded locator pins that drop into holes on the female side to take up the torque. In the photography world, these are AARI pins. To us they just seem like a good idea.

Maybe you don’t see the point of avoiding redesigning the wheel every time for custom mounts and brackets. After all, that lets you come up the the ideal solution every time. On the other hand, [Mansour] has both simplified his design process and made decades worth of camera-holding objects — everything from tripods to stabilizing gimbals — accessible to all his stuff. It’s an interesting idea, and his full blog post is worth a read, even if it’s not likely the EU is going to force its adoption like it did USB-C.

Train Simulator Controller: July 2026 Progress Roundup

August 5, 2026 by Maya Posch No comments

For the past three years [Christopher Mitchell] has been working on his replica of a British Rail Class 800 control cab for a physical train simulator, with the July blog update providing many details on the progress.

The Class 800 series of trains is relatively new, having first entered service in the UK in 2017 on the Great Western Railway (GWR). Designed and built by Hitachi as part of their modular AT300 product series, they come in both purely electrical and diesel-electric hybrid configurations to deal with non-electrified rail sections.

Replicating the experience of driving a train is always a trade-off between what one would like and what is practical or affordable. With only a corner of his apartment to work with, [Christopher] has opted to focus on the instruments and controls in the cab, using real components where possible or building replicas for the remainder.

This entire control panel is to be used with simulators like Train Simulator and Train Sim World, using their controller APIs to both control the in-game train as well as to get feedback to be displayed on the real instruments and the various LEDs, such as those that indicate the state of the external lights. These are all controlled internally via a CAN bus, as is typical.

These instruments include genuine AWS sunflowers, part of the safety system that ensures that a driver has acknowledged a non-clear signal along the track. It’s another nice touch to a control cab simulation that’s shaping up to be rather close to the real deal.

Even if for the average person something like a Densha de Go! copy and associated controllers will likely suffice, there’s a lot to be said for having something closely resembling the real deal for a realistic game, whether it’s a train, car or airplane controller and associated instrumentation.
