Until a flood claimed its life, the 386 tower [Tylinol] found on the side of the road served him well as a DOS gaming rig. In the aftermath of the flood, the machine was left with ruined internals and a rusted case; it ended up being tossed in storage where it was slowly rotting away. But a recent idea got him to drag this old dinosaur back out into the light of day and give it a new lease on life with some modern gear.
For our viewing pleasure [Tylinol] documented the restoration of the computer, dubbed SErEndIPITy, from start to finish. The rebuild starts with tearing the machine down to the steel frame and sanding all the rust off. Luckily it looks like no structural damage was done, and a coat of engine enamel got the frame looking more or less like new. The original motherboard mounting solution wouldn’t work for his modern board, so he ended up riveting a piece of sheet metal in and drilling new holes for standoffs to thread into.
A nice element of this rebuild is that [Tylinol] didn’t want to drastically change the outward appearance of the machine. The customary yellowed plastic was left alone, and wherever possible the original hardware was reused. Rather than blow a hole in the case, he took his Dremel to the decorative ribbed design of the front panel and turned it into a stock-looking vent.
The real star of this rebuild is the LED CPU “Speed” display on the front of the case. In its original form, this was a fake display that simply cycled through predefined digits when you pressed the “Turbo” button on the front panel. By grounding them one at a time, [Tylinol] figured out which lines on the PCB controlled each segment of the display and wired it up to a Teensy 3.5. He was then able to write a C# plugin for CoreTemp to display the temperature.
The rebuilt machine is packing an i5-6500 processor, GTX 970 video card, and 8 GB of DDR4 RAM. Not exactly a speed demon compared to some of the modern desktops out there, but it certainly beats the original hardware. Incidentally, so does the Teensy 3.5 controlling the front panel display. There’s a certain irony there…
Cramming modern hardware into the carcass of an outdated computer is nothing new, of course. But we especially like the builds that take the time to make it all look stock.
There are a lot of cool ways to wrap a case around your custom PC build. But the off-the-shelf stuff doesn’t really set your machine apart from the herd, no matter how many RGB LEDs you put inside. If you really want to stand out, think out of the box, and build your PC into the case of an old logic analyzer.
Looking for a little retro cool factor, [Bob Alexander] turned to the world’s boneyard, eBay, and rounded up a dead H-P 1653 logic analyzer. State of the art in 1989 but not worth repairing by [Bob]’s lights, so he proceeded to remove the original 10″ CRT to make room for an alternate display. After a bit of experimentation, he settled on an LCD panel mounted behind a sheet of acrylic that he thermoformed to the shape of the CRT face. All the original guts were removed to make way for the motherboard and power supply, and a custom PCB to interface the original keypad and rotary encoder into the PC. The old buttons now launch various programs and the encoder acts as the PC volume control. The floppy drive made way for a USB hub, the BNC connectors became power and reset buttons, and a photo taken through the CRT bezel before the electronics were removed provides a window into the soul of the original instrument. It’s a really nice build, and totally unique.
Need some inspiration for your custom case mod? This wall-mounted render farm is pretty snazzy. Or perhaps you’d prefer something more apocalyptic, like this ammo can PC.
Remember the days when the television was the most important appliance in the house? On at dawn for the morning news and weather, and off when Johnny Carson said goodnight, it was the indispensable portal to the larger world. Broadcast TV may have relinquished its hold on the public mind in favor of smartphones, but an information portal built into an old TV might take you back to the old days.
It seems like [MisterM] has a little bit of a thing for the retro look. Witness the wallpaper in the video after the break for proof, as well as his Google-ized Radio Shack intercom project from a few months back. His current project should fit right in, based on an 8″ black-and-white TV from the 70s as it is. TVs were bulky back then to allow for the long neck of the CRT, so he decided to lop off the majority of the case and use just the bezel for his build. An 8″ Pimoroni display sits where the old tube once lived, and replicates the original 4:3 aspect ratio. With Chromium set up in kiosk mode, the family can quickly select from a variety of news and information “channels” using the original tuning knob, while parts from a salvaged mouse turns the volume control into a scroll wheel.
It’s a nice twist on the magic mirror concept, and a little different from the other retro-TV projects we’ve seen, like a retro gaming console or an old-time case for a smart TV.

YouTube User [Vuaeco] has come up with a novel idea, combining power tool battery packs to double the capacity.
Starting off with two slimline 2.0Ah compact battery packs, [Vuaeco] wanted a larger 4.0Ah rebuilt drill battery pack. These battery packs are different in size so it wasn’t just a case of adding in more cells in empty slots, instead he goes on to show us how to connect the batteries in parallel using some thin nickel strips. Once completed he modifies the battery casing so it fits another stack of batteries. He does this by bolting the top and bottom together with long screws, and insulating the otherwise exposed battery terminals with insulating tape. The final product isn’t as aesthetically pleasing as a real battery pack, but it looks good enough.
There are a few things we might have done differently, for instance providing some hard plastic around the insulation so should the battery get knocked in an awkward position it would still have a hard shell protecting it. Also, instead of combining the batteries together fully charged as the video suggests, we might have done the opposite approach and fully drained them, avoiding unnecessary risks. If you try this, how about giving it a 3D printed case?

We see a lot of old radio restoration projects around here, and we have to admit to having mixed emotions about some of them. It seems a shame to go through the effort to lovingly restore a vintage Art Deco case only to stuff it with a Raspberry Pi and Bluetooth. Seems like if you’re going to restore a radio, go all the way and bring the original electronics back to life. But this radio “restoration” avoids that issue altogether by cleverly concealing a full PC build in a vintage radio case.
Clearly a labor of love, [SolomonZaraa]’s two-year effort guts the radio but still manages to pay homage to the original beauty of the 1939 vintage Philco 39-80 “tombstone” portable AM radio. The first design decision was to retask the original tuning dial as an analog thermometer using an Arduino and a servo. Then a new back was added with an extension for the motherboard and PSU, a drive cage was added, and a surprise slot for the DVD drive was built into the speaker grille. Nice brass trim and a good refinishing of the case resulted in an impressive and unexpected presentation.
You don’t have to go far in the Hackaday Wayback machine to find an antique radio with updated audio, but we’re pretty sure this is the first antique radio PC case mod we’ve seen. Nicely done, [Solomon]!
Since the release of the Raspberry Pi, the hallowed tradition of taking game consoles, ripping all the plastic off, and stuffing the components into nice, handheld form factors has fallen off the wayside. That doesn’t mean people have stopped doing it, as [Akira]’s masterful handiwork shows us.
This casemod began with a Nintendo GameCube ASCII keyboard controller, a slightly rare GameCube controller that features a full keyboard smack dab in the middle. While this keyboard controller was great for Phantasy Star Online and throwing at the TV after losing Smash, the uniqueness of this controller has outshadowed its usefulness. [Akira] began his build by ripping out the keyboard and installing a 7 inch LCD. It fits well, and makes for a very unique GameCube case mod.
The rest of the build is about what you would expect – the motherboard for a PAL GameCube is stuffed inside, a quartet of 18650 batteries provide the power, and the usual mods – a memory card is soldered to the motherboard and an SD Gecko allows homebrew games and emulators to be played.
The completed project is painted with the same theme as [Samus Arans]’ Varia suit, making this a one of a kind casemod that actually looks really, really good.
For those of us with space to spare, our workbenches tend to sprawl. The others who are more space limited will certainly feel envy at [Love Hultén]’s beautiful Tempel workbench.
The workbench appears at first to be a modern interpretation of a secretary’s desk. There are some subtle hints that it is no ordinary piece of furniture. The glowing model of our solar system on the front, for example.
With the front folded down, rather than the expected leather writing pad and letter sized drawers, a few more oddities become apparent. The back is a pegboard which holds a small selection of tools. To the left, a checkered grid obscures speakers. Knobs control volume There are even USB ports. On the right sits another speaker. Banana jacks let you use the analog voltmeter. Most appealingly, the indestructible Hakko 936 soldering iron has been entirely integrated into the structure of the desk.
If you press the right button on the front, the desk will reveal its last secret. It contains an entire workstation somewhere behind the array of drawers on the front. A linear actuator pushes a computer monitor up from inside the cabinet, covering the pegboard in the back. Awesome.
There is a build log, but unfortunately it’s been imageshacked and only the words remain. We think [Love Hultén] has finally managed to build a soldering station that’s welcome in every room of the house except for the garage.
