A Real All-In-One Printer Should Have A Computer In It, Too

August 16, 2019 by Dan Maloney 14 Comments

With printers generally being cheaper to replace than re-ink, there are plenty of cast-offs around to play with. They’re a great source for parts, but they’re also tempting targets for repurposing for entirely new uses. Sure, you could make a printer into a planter, but slightly more useful is this computer built into a printer that still prints.

This build is [Mason Stooksbury]’s earlier and admittedly useless laptop-in-a-printer build, which we covered a few months back. It’s easy to see where he got his inspiration, since the donor printer’s flip-up lid is a natural for mounting a display, and the capacious, glass-topped scanner bed made a great place to show off the hybrid machine’s guts. But having a printer that doesn’t print didn’t sit well with [Mason], so Comprinter II was born. This one follows the same basic approach, with a Toshiba Netbook stuffed into an H-P ENVY all-in-one. The laptop’s screen was liberated and installed in the printer’s lid, the motherboard went into the scanner bay along with a fair number of LEDs. This killed the scanner but left the printer operational, after relocating a power brick that was causing a paper jam error.

[Mason]’s Comprinter II might not be the next must-have item, but it certainly outranks the original Comprinter on the utility spectrum. Uselessness has a charm of its own, though; from a 3D-printed rotary dial number pad to a useless book scanner, keep the pointless projects coming, please.

Original Xbox Gets Hardware Transplant, And Is Very Fast

January 24, 2019 by Lewin Day 54 Comments

The original Xbox launched way back in 2001, to much fanfare. This was Microsoft’s big first entry into the console market, with a machine packing a Pentium III CPU, and commodity PC hardware, contributing significantly to its bulk. Modding was a major part of the early Xbox scene, and as the original hardware has grown too feeble to keep up with modern tasks, enterprising makers have instead turned to packing the black box with modern hardware. The team at [Linus Tech Tips] decided that other builds out there weren’t serious enough, and decided to take things up a notch.

The build starts with a passively cooled compact power supply, a Core i5 8400 6-core CPU, and a GeForce RTX2070 to handle graphical tasks. Parts were carefully selected for a combination of performance, packaging, and with an eye to the thermal limits inherent in stuffing high-powered modern hardware into a tight Xbox shell.

All manner of oddball techniques are used to make the build happen. The GPU is connected through a PCI Express cable, which we were surprised to learn was a thing, given the nature of high-speed signals and long transmission lines. The Xbox shell had its original metal insert and plastic standoffs removed, with an aluminium inner shell being CNC cut and bent up on a pan brake to act as a new internal chassis. There’s yet more carnage to come, as the GPU has its extraneous DVI port hacked off with a grinding wheel.

In the end, after much cutting and cajoling, the parts come together and fit inside the case, making the sleeper build a reality. It’s fun to watch the team fiddle with config files and struggle to load and play local multiplayer games, as they realise that there are just some things that consoles do better.

Regardless, it’s an impressive casemod that goes to show what you can pull off with some off-the-shelf parts, a well-stocked workshop, and some ingenuity. If you’re looking for more case mod inspiration, try out this all-in-one printer build. Video after the break.

Case Mod Takes “All In One” Printer To The Next Level

May 15, 2018 by Tom Nardi 14 Comments

You’ve seen printers with scanners in them, printers with copiers in them, even ones with the ancient technology known as “facsimile” built-in. But have you ever seen a printer with a full gaming computer built into it? No? Well, you still haven’t, technically. There’s no printer to be had anymore inside this re-purposed HP Photosmart 6520 case, but it’s probably the closest we’re going to get.

[Jacob Lee] wrote in to share this awesome build with us, which sees the motherboard, graphics card, ATX power supply, and hard drives all fit seamlessly into the shell of a disused “All-in-one” style printer. Incredibly, he even managed to integrate an LCD into the top; which hinges open when in use and gives a look down into the madness that makes this build tick.

To say there’s a lot of hardware packed into this thing is an understatement. Which is all the more impressive when you consider that he] didn’t take the easy way out for any of it. He could have used a mini-ITX motherboard, or a slim PSU. He could have even dropped the graphics card for integrated. No, [Jacob] is clearly a subscriber to the “Go big or go home” ethos.

As if putting all this gear inside of a normal looking printer case wasn’t impressive enough, he even went as far as adding female ports for Ethernet, HDMI, and USB on the rear of the device to give it a stock look. He mentions there’s some room for improvement with the USB ports, but the power switch and IEC port really look like they could have been original components.

In the age of the Raspberry Pi and other diminutive computers, we don’t see too many proper desktop computer projects anymore. Fewer still that are so well executed and creative. We don’t know how many other people might be trying to stick a computer in a printer case, but if they’re out there, the bar has just been set pretty high.

High End PC Gets A Rustic Woodworking Piece Of Art For A Case

May 4, 2018 by James Hobson 17 Comments

As [Matt] from [DIY Perks] was about to assemble a new PC, he decided to take a unique direction when it came to building a case. Despite the appearance of a woodworking piece with weird industrial radiators, there is actually a full-fledged, high-end PC hidden inside.

Those radiators are a pair of almost-the-biggest-you-can-buy heatsinks — one of which has been modified to fit the graphics card. Separating the graphics card’s stock cooling fan unit cut down significantly on noise and works with the stringent space requirements of the build. Those fans however keep other components on the card cool, so [Matt] cut pieces of copper plate to affix to these areas and joined them to the heatsink with a heat pipe, bent to shape. The elm wood case then began to take shape around the graphics card — cut into pieces to accommodate the heat pipes, and sealed with black tack to dampen the ‘coil whine’ of the GPU; it turns out the likely culprit are the MOSFETs, but close enough.

Stretched PC Case Turned GPU Cryptominer

February 23, 2018 by Tom Nardi 39 Comments

We don’t do financial planning here at Hackaday, so we won’t weigh in on the viability of making money mining cryptocurrency in such a volatile market. But we will say that if you’re going to build a machine to hammer away at generating Magical Internet Monies, you might as well make it cool. Even if you don’t turn a profit, at least you’ll have something interesting to look at while you weep over your electricity bill.

Sick of seeing the desktop machine he built a decade ago gathering dust, [plaggle24w5] decided to use it as the base for a cryptocurrency mining rig. Of course, none of the original internals would do him any good, but the case itself ended up being a useful base to expand on. With the addition of some 3D printed components, he stretched out the case and installed an array of video cards.

To start with, all the original plastic was ripped off, leaving just the bare steel case. He then jammed a second power supply into the original optical drive bays to provide the extra power those thirsty GPUs would soon be sucking down. He then designed some 3D printed arms which would push out the side panel of the case far enough that he could mount the video cards vertically alongside the case. Three case fans were then added to the bottom to blow air through the cards.

While [plaggle24w5] mentions this arrangement does work with the case standing up, there’s obviously not a lot of air getting to the fans on the bottom when they’re only an inch or so off the ground. Turning the case on its side, with the motherboard parallel to the floor, allows for much better airflow and results in a measurable dip in operating temperature. Just hope you never drop anything down onto the exposed motherboard…

Mining Bitcoin on desktop computers might be a distant memory, but the latest crop of cryptocurrencies are (for now) giving new players a chance to relive those heady early days.

Flood Damaged 386 Gets A Modern Rebuild

February 11, 2018 by Tom Nardi 28 Comments

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.

Old Logic Analyzer Becomes New PC Case

December 31, 2017 by Dan Maloney 26 Comments

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, he removed 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.
