After [Travis]’s media server died a couple months ago, his brother [Nick] secretly plotted to replace it for Christmas. Admitting it to be an “asinine Rube Goldberg” arrangement, [Nick] wanted something custom and remarkable for his sibling. Rather than go the normal SATA route, 38 USB hot-swap laptop drives were clustered together inside a custom leather enclosure with a bronzed glass top.
[Nick] picked up 45 of the 500GB drives for only $350 and designed the project around those. He spent $1000 on matching metal docks for each of them, powered by $800 worth of PCIe quad independent USB controllers – no hubs. A $550 Xeon motherboard with 14 USB ports, 16GB of RAM, a basic video card and a 1000W power supply rounded out the electronics.
Under Windows 8.1 all drives are arranged in a single giant array under Storage Spaces, no raid.
Everything was built into a wood-framed coffee table wrapped in high-end leather that [Nick] spent 65 hours hand stitching himself. Fancy brass corner braces hold the frame square. All the wires were run underneath the table so the visible surfaces are clean and clear. The table structure is lifted up on legs made from half-inch square barstock bent into a hairpin and bolted to the underside.
All together [Travis]’s Zerg-Berg media server cost in the range of $4500. [Nick] intends it to be something that lasts him a very long time.
See the video below for [Nick]’s
rationalization explanation of the hardware and methods chosen.

Either in need of a coffee table or suffering a severe lack of upscaled electronics, [Darren] just finished up a great build for his living room. It’s a huge, scaled up version of a UV erasable EPROM with an infinity mirror in place of the fused quartz window.
[Darren]’s coffee table was inspired by an earlier build by the geniuses at Evil Mad Scientist. A few years ago, they built a 555 footstool that was scaled up about 30 times its normal size. Even at footstool scale, the 555 is still relatively tiny.
[Darren] is using a similar construction technique by forming the legs of the EPROM out of laminated plywood. Since this build is significantly larger, building the entire device out of solid, laminated plywood would result in an unwieldy and expensive piece of furniture. Instead, [Darren] constructed the legs and sides out of plywood laminations, covering the ends, top, and bottom with plywood panels. The result is a hollow EPROM/coffee table that’s still structurally sound.
If you’re a bit confused after counting the number of pins on the coffee table, you’re in good company. This is technically a scaled-up version of a 16-pin 0.600″ PDIP, something that a quick googling suggest isn’t historically accurate. Maybe there was an EPROM with a 4-bit wide data bus somewhere in the annals of electronics history, but we’re happy with saying that a completely accurate scaled-up ROM would be far too big for [Darren]’s living room.

[johannes] writes in with a pretty impressive LED table he built. The table is based around WS2801 serially addressable LEDs which are controlled by a Raspberry Pi. The Pi serves up a node.js-driven web interface developed by [Andrew Munsell] for a room lighting setup. The web interface controls the pattern shown on the display and the animation speed.
[johannes] built a wooden coffee table around the LED matrix, which includes a matte glass top to help diffuse the lighting. An outlet to plug in a laptop and two USB charging ports are panel-mounted on the side of the enclosure, which are a nice touch. The power supply for the LEDs is also inside the enclosure, eliminating the need for an external power brick.
While [johannes] hasn’t written any software of his own yet, he plans on adding music synchronization and visualizations for weather and other data. Check out the video after the break to see the table in action.

[Matt Silver] usually enjoys a cup of tea in the evening. Unfortunately, this habit can be frustrating and dangerous while sitting in bed. He rectified the problem by building this awesome space-saving table, which can be stored on the ceiling of all places! Depending on the supplies you might already have, this could be a relatively cheap build of about $40 or less. [Matt’s] using pine board for everything, but notes you could save time and money by re-purposing an existing coffee table. You will, however, need to make the ceiling frame to support it.
At the heart of this build is our favorite rope—Paracord 550. [Matt] used a single piece to tie the whole thing together, which can cause the table to lower crooked, but [Matt] found he can keep it level by putting a hand on it while it descends. You also get mechanical advantage from the pulleys this way! If you’re not crazy about the potential unevenness, you could redesign the pulley and eyelet layout to allow for four ropes to ensure a reliably horizontal surface.
Why not pair this idea with the portable electronics lab we shared a few days ago? You could have a full series of drop-down tool labs in your workshop. Think of all the space saving opportunities!
[Flyingpuppy] sent us this tip about her cleverly-concealed pull-out lightbox drawer. Her resolution for the new year was to make more art, so she filled this coffee table with art supplies and decided she’d draw while relaxing in front of the television. She also wanted a lightbox nearby, which originally involved hacking the entire tabletop with some acrylic, but she eventually opted for a simpler build: and it’s portable, too! The drawer’s lights are battery-powered, so you can pull the entire thing out of the table and drag it onto your lap, if that makes drawing more comfortable.
[Flyingpuppy] sourced seven inexpensive LED units from her local dollar store, which she mounted to the back of the drawer with some screws. The rest of the drawer was lined with white foam board, the bottom section angled to bounce light up onto the acrylic drawing surface. Because she needs to open the case to manually flip on the lights, she secured the acrylic top magnetically, gluing a magnet to the underside of the foam board and affixing a small piece of steel to the acrylic. A simple tug on the steel bit frees the surface, providing access underneath. Stick around for a video below.

First a quick announcement. We changed our “Kickstarter” category to “Crowd Funding“. We get a huge number of tips about crowd funding projects. We’re always interested in details. If you’re trying to get your crowd funding campaign on our front page make sure you’ve shared as many gritty project details (development process, problems/successes along the way, etc.) as possible . We usually prefer if this is done in a separate blog post from the campaign page itself.
Here’s a peephole hack that purportedly cost four grand. It uses a full on DSLR for the peephole hardware. Add a motion sensor and maybe you’ll be able to learn the faces of the neighbors who live on your floor. [via Gizmodo]
[Matthias] tells us that support for Rigol DS1052E oscilloscopes has been included in the 3.11 version of the Linux Kernel. Prior to this, getting the hardware to work on Linux was a hack, and a buggy one at that. For what it’s worth, here’s confirmation that support was added.
A post about reverse engineering the FitBit Aria Wi-Fi scale was sent in by [Christopher]. This makes us wonder if you could patch into a digital scale, using your own electronics to spoof the FitBit version?
We always keep our paperboard six-pack carriers so that we have a way to transport our homebrew beer. But rolling into a party with this laser-cut beer caddy which [Daniel] designed looks a lot cooler.
Texas Instruments has an MSP430 Selection Guide (PDF) which we found interesting. The first nine pages or so are pretty much just marketing, but several pages of parametric tables found after that make for a great collection of data on the hardware families. [via Dangerous Prototypes]
[Antoine] spared no expense building a coffee table that showcases his old motherboards. The illuminated glass and wood art piece rang in at around $400 in materials. We’re a little more minimalist with our home decor. We still want something along the lines of this LED matrix version.
Speaking of LED matrices, [Mario] dropped off a link to his LED Space Invaders game in the comments of last week’s Game of Light post. What we can’t figure out is why so many people hesitate to send in a tip about their awesome projects?
[Hoogen] did a fantastic job of building arcade hardware into this Ikea coffee table. Sound familiar? We just looked at another Ikea coffee table arcade, but this one goes quite a different route. It uses a Ramvik table which has a very deep drawer in the end where the controls are located. The image to the left shows that you’re going to have a problem with the joystick when you try to close it. [Hoogen] came up with a clever mechanism to overcome this issue.
This is not an emulated system. It uses a JAMMA board called the iCade 60-in-1 to bring sixty classic arcade games to the build. To interface with this hardware [Hoogen] included a JAMMA full cabinet wiring harness. The inset image on the right is pretty small, but it shows the speaker mounted in the back of the drawer, as well as the control surface angled down. This tilting surface is what allows the controls to move out of the way when closing the drawer. This happens automatically as described by [Hoogen] in his write-up.
