A Handheld Gaming PC With Steam Deck Vibes

Since its inception, the Steam Deck has been a bit of a game changer in the PC gaming world. The goal of the handheld console was to make PC gaming as easy and straightforward as a walled-garden proprietary console like a Switch or Playstation but still allow for the more open gaming experience of a PC. At its core, though, it’s essentially a standard PC with the parts reorganized into handheld form, and there’s no reason any other small-form-factor PC can’t be made into a similar system. [CNCDan] has the skills and tools needed to do this and shows us how it’s done.

The build is based around a NUC, a small form factor computer that typically uses the same low-power mobile processors and graphics cards found in laptops but without the built-in battery or screen. This one has an AMD Ryzen 7 processor with Radeon graphics, making it reasonably high-performing for its size. After measuring out the dimensions of the small computer and preparing for other components like the battery, joysticks, buttons, and even a trackpad, it was time to create the case. Instead of turning to a 3D printer, this one is instead milled on a CNC machine. Something tells us that [CNCDan] prefers subtractive manufacturing in general.

With all the parts assembled in the case, the build turns into a faithful Steam Deck replica with a few bonuses, like an exposed Ethernet port and the knowledge that everything can easily be fixed since it was built from the ground up in the first place. The other great thing about builds like these is they don’t need an obscure NUC for the hardware; you can always grab your old Framework mainboard for handheld gaming instead. Reminded us of the NucDeck.

Classic LED Bubble Displays Ride Again

Hewlett-Packard used to make some pretty cool LED displays, many of which appeared in their iconic pocket calculators back in the 1970s and 1980s. [Upir] tracked down some of these classic bubble displays and used them with a microcontroller. We love the results!

The displays featured here, the HPDL-1414, aren’t quite what would have been found in an HP-35, of course. These displays have 16 segments for reasonably legible approximations of most of the ASCII character set. Also, these aren’t just the displays; rather, a pair of the bubble-topped displays, each with four characters, is mounted to a module that provides a serial interface. [Upir] found these modules online, but despite the HP logo on the PCB silkscreen, it’s not really clear who made them. The documentation was a bit thin, to say the least, but with a little translation help from Google, he figured out the serial parameters and the character encoding. The video below shows him putting these modules through their paces.

Unusually for [upir], who has made a name for himself hacking displays to do things they weren’t designed to do, he stuck with the stock character set baked into this module. We think it would be fun to get one of these modules and hack the firmware to provide alternative character sets or even get a few of the naked displays and build a custom interface. Sounds like a fun rainy-day project.

This reminded us of another HP display project we saw a while back. Or, roll your own displays.
