Unless you’ve spent some time in the industrial electrical field, you might be surprised at the degree of integration involved in the various control panels needed to run factories and the like. Look inside any cabinet almost anywhere in the world, and you’ll be greeted by rows of neat plastic terminal blocks, circuit breakers, signal conditioners, and all manner of computing hardware from programmable logic controllers right on to Raspberry Pis and Arduinos.
A well-crafted industrial control panel can truly be a thing of beauty. But behind all the electrical bits in the cabinet, underneath all the neatly routed and clearly labeled wires, there’s a humble strip of metal that stitches it all together: the DIN rail. How did it come to be, and why is it so ubiquitous?

DRM has become a four-letter word of late, with even media companies themselves abandoning the practice because of how ineffective it was. DRM wasn’t invented in the early 2000s for music, though. It’s been a practice on virtually everything where software is involved, including arcade cabinets. This is a problem for people who restore arcade machines, and [mon] has taken a swing at unraveling the DRM for a specific type of Konami cabinet.
The game in question, Reflec Beat, is a rhythm-based game released in 2010, and the security is pretty modern. Since the game comes with a HDD, a replacement drive can be ordered with a security dongle which acts to decrypt some of the contents on the HDD, including the game file and some other information. It’s not over yet, though. [mon] still needs to fuss with Windows DLL files and a few levels of decryption and filename obfuscation before getting the cabinet functional again.
The writeup on this cabinet is very detailed, and if you’re used to restoring older games, it’s a bit of a different animal to deal with than the embedded hardware security that older cabinets typically have. If you’ve ever wanted to own one of these more modern games, or you’re interested in security, be sure to check out the documentation on the project page. If your tastes are more Capcom and less Konami, check out an article on their security system in general, or in de-suiciding boards with failing backup batteries.
If you are going to do something as a joke, there is nothing to say that you can’t do a nice job of it. If you’re like [Michael], a whimsical statement like “Wouldn’t it be funny to put Gründerzeit-style doors on the server cabinet?” might lead down a slippery slope. True to his word, [Michael] not only installed the promised doors, but he did a darn nice job of it.
Buying new doors was the easy part because the door frame and hinges were not standardized back then, so there was nothing on the server cabinet to his mount doors. He walks us through all the steps but the most interesting point was the 3D printed door hinges which [Michael] modeled himself and printed in steel. His new hinges feature his personal flair, with some Voronoi patterning while matching the shape of the originals. We love seeing 3D printed parts used as functional hardware, and hinges are certainly a piece of hardware meant to hold up under pressure.
This is not the first 3D printed door hardware we’ve seen. Check out this innovative latch printed as a single piece and here’s the skinny on making flexible objects yourself.

A well-stocked liquor cabinet is a necessity for the classy gentleman or gentlelady who likes to entertain. Having the proper spirits and mixers on hand to make anything from a martini to a sidecar is always a solid way to ensure guests have a good time at your cocktail party. In the past, a beautifully crafted cherry or walnut liquor cabinet was enough to impress visitors with your affluence. These days, if you don’t want to look like a pauper, you have to take it a step further.
[Elias Bakken] and his uncle [Mike Moulton] have decided to take liquor cabinets into the 21st century with a semi-automatic liquor cabinet called Latskap. The project is still in progress, and in the prototyping stage, but their build log on Hackaday.io is showing a lot of potential. It shouldn’t be long before they have a fully functional prototype finished.

We see an awful lot of arcade cabinets around here, and so it’s pretty unusual for a build to get much more than a second glance. But, this beauty is just too good not to mention. The entire build, named “Ready Player One” as a nod to the engrossing Ernest Cline novel, is detailed in [scoodidabop’s] post on Reddit.

Let’s face it, we all love arcades, but not all of us can fit a full size stand-up in our homes. [Bentika] knew the solution was a bartop style cabinet, but it had to be designed and built to his specifications. You see, [bentika] is an aspect ratio nerd. Only a proper 4:3 screen would do for emulating games designed for just such a display. Modern 4:3 displays are hard to come by, unless of course you have an iPad handy. The 1024 x 768 screens used on the early model iPads are perfect for the task.
Driving these screens used to be a chore, but thanks to hacker reverse engineering and overseas manufacturing, these days, controllers are only a few clicks away. [Bentika] ordered a controller for the iPad 1 screen from eBay. What he got was a controller that only worked with the iPad 2 screen. Thankfully he had a pile of old iPads to play with, so it wasn’t an issue.
[Bentika] designed his cabinet using AutoDesk 123D based upon reddit user [joshendy’s] basic outline. His final cut patters were created with Adobe Illustrator. He was able to get the entire cabinet laser cut for around $160, including materials. Cabinet assembly was easy, thanks to plenty of square gussets used to align the various pieces.
The controller for this arcade is of course a Raspberry Pi 2 running RetroPie. [Bentika] used a control block to interface the joystick and buttons to the Pi itself. RetroPie lends itself to “keyboardless” operation, he didn’t have to bring any of the Pi’s USB ports outside the case.
We have to say the final results are very nice. This system has all the portability of a CRT based bartop setup without the weight. You can check out more discussion of this hack over on [Bentika’s] Reddit thread, or click past the break for the video.
