Travel Uke From A Fallen Tree

December 12, 2022 by 6 Comments

When faced with what to build from the trimmings of the walnut tree in her yard, [Amy Qian] decided to build a headless travel ukulele. [via MAKE:]

Headless instruments relocate the tuners to the body of the instrument, and [Qian] had to do a fair bit of trimming and whittling on the body to make the tuners fit just right and still be operable via four scoops cut into the sides. After some initial troubles with the amount of friction on the strings produced by the mandrel, she replaced it with a set of ball bearings and a holder she machined out of aluminum.

We love how [Qian]’s extensive build log goes through the entire process of making this diminutive instrument from trimming dead walnut branches to building a playable instrument. Little details like the maple strip in the neck and the cocobolo accents really take this far beyond the cigar box instruments that start many down the path of luthiery.

Clean Slate Is A Vintage Amplifier-Inspired PC

December 9, 2022 by 9 Comments

Hacks that bring a vintage flair to modern electronics never get old, and [Jeffrey Stephenson] delivers with his Project Clean Slate inspired by vintage tube amps.

Thinking outside the traditional single box PC, [Jeffrey] built his computer into a series of component-specific boxes all attached to a platform housing the Micro ATX motherboard. The base is made of plywood with a birds-eye maple veneer and each of the component boxes features two different sizes of wire mesh to manipulate the viewer’s perception of the dimensions. Even the I/O and graphics card plates are custom made from aluminum for this build.

If you really want to dig into how this PC came to life, there’s a very detailed build log including every step of the process from bare board to finished product. We love when we get an inside look at the thought process behind each design decision in a build.

We’ve featured [Jeffrey] before with his Humidor Cluster, and you may also like this PC inside a vintage radio.

Mechanical Keyboard With A Framework Inside

November 30, 2022 by 31 Comments

Like the Commodore 64 and other keyboard computers of yore, the [Elevated Systems]’s CJ64 fits all of its processing and I/O into a single keyboard-shaped package.

This iteration of the project takes it to the next level with an enclosure milled out of aluminum instead of the mere 3D printed enclosure of the previous versions. With a Framework mainboard, the ports are configurable via the Framework expansion card system giving you even more options to customize this build. To round it out, this keyboard PC doesn’t scrimp on the keyboard part either with mechanical switches and MT3 profile keycaps.

If you’d like to build one of these for yourself, [Elevated Systems] has uploaded the 3D printed enclosure files to his GitHub repository. The files for machining are available as well, but only to patrons.

Are Slabtops The Future Of Computing?

November 25, 2022 by 114 Comments

The most popular computer ever was the Commodore 64 with its computer-in-a-keyboard form factor. If you have a longing for a keyboard computer with more modern internals, one of the easiest solutions today is to pull the screen off a laptop.

[Umar Shakir] wanted to see what the fuss was about regarding a recent Apple patent and took the top lid off of his M1 Macbook Air and turned it into a “slabtop.” The computer works great wired to a monitor but can also be used wirelessly via AirPlay. The approach doesn’t come without its downsides, of course. Newer MacBooks can’t access recovery mode without the built-in screen, and some older models had their WiFi antennas in the top lid, so making one into a slabtop will leave you desk-bound.

While [Shakir] focuses on MacBooks, this approach should work with any laptop. Apparently, it’s a cottage industry in China already. Back in the day, my own daily driver was a Pentium-powered laptop with its broken LCD (and lid) removed. It worked great with whatever CRT was nearby.

TinyLlama Is A 486 In Your Pocket

November 20, 2022 by 39 Comments

We love retrocomputing and tiny computers here at Hackaday, so it’s always nice to see projects that combine the two. [Eivind]’s TinyLlama lets you play DOS games on a board that fits in your hand.

Using the 486 SOM from the 86Duino, the TinyLlama adds an integrated Crystal Semiconductor audio chip for AdLib and SoundBlaster support. If you populate the 40 PIN Raspberry Pi connector, you can also use a Pi Zero 2 to give the system MIDI capabilities when coupled with a GY-PCM5102 I²S DAC module.

Audio has been one of the trickier things to get running on these small 486s, so its nice to see a simple, integrated solution available. [Eivind] shows the machine running DOOM (in the video below the break) and starts up Monkey Island at the end. There is a breakout board for serial and PS/2 mouse/keyboard, but he says that USB peripherals work well if you don’t want to drag your Model M out of the closet.

Portable Monitor Extension For Nintendo Switch

November 16, 2022 by 7 Comments

Handheld consoles are always a tradeoff between portability and screen real estate. [Pavlo Khmel] felt that the Nintendo Switch erred too much on the side of portability, and built an extension to embiggen his Switch. (YouTube)

[Khmel] repurposed a Dell XPS 12 LCD panel for the heart of this hack and attached it to an LCD controller board to serve as an external monitor for the Switch. A 3D printed enclosure envelops the screen and also contains a battery, speakers, and a dock for the console. Along the top edges, metal rails let you slide in the official Joy-Cons or any number of third party controllers, even those that require a power connection from the Switch.

Since the Switch sees this as being docked, it allows the console to run faster and at higher resolution than if it were in handheld mode. The extension lasts about 5 hours on battery power, and the Switch inside will still be fully charged if you don’t mind being constrained to its small screen while you charge it’s bigger-screened exoskeleton.

Shrinking The XBox 360

November 15, 2022 by 5 Comments

One of the coolest things in the retro gaming scene is making desktop consoles into portables. [Millomaker] is building an XBox 360 handheld, and the first step is shrinking the console’s motherboard.

Most 360 portables up to this point have been laptop-shaped instead of something handheld, but that hasn’t stopped people from trying to miniaturize the console further. [Millomaker]’s cut seems to be the most successful so far, shrinking the device’s motherboard down to the size of its old competitor, the Wii.

In the video (in French with available auto-translation) below the break, you can get the full harrowing journey during which several 360s sacrificed their motherboards for the cause despite [Millomaker]’s meticulous testing between component removals. This is truly an awesome mod, and we’re glad that the video shows not only the successes, but also the missteps on the way. It wouldn’t really be a hack if it was smooth sailing, would it?
