Mame cabinet springs to life from Ikea furniture

[Jed] built a MAME cabinet into some flat pack furniture (translated). For the housing he chose an Ikea Ramvik side table. This is a perfect piece of furniture for the project for several reasons; it’s cheap, coming in at under $70, it’s a reasonable height to use while sitting on the sofa, it has a built-in drawer that will hide the guts of the system, and it was designed to use a piece of glass as the table surface.

The electronics are pretty straight forward. A notebook computer runs the MAME frontend, with an auxiliary screen which is framed nicely under the glass. Controls are standard coin-op type buttons soldered to the contacts on the PCB from a USB joystick. The brushed aluminum bezel added to the surface of the table keeps the modern finished look that one would want with a showpiece like this one.

We always like to keep our eyes open for hackable items when visiting Ikea. Make sure to check out their As-Is department (preferably as soon as they open) to find hackable furniture on the cheap.

Roller curtains with your graphics on them

[Lenore] added a bit of customization to her office window hangings by fitting roller curtains with custom printed fabric. The treatment seen above is a $20 Enje roller blind from Ikea but that logo is all Evil Mad Science. The weight at the bottom of the fabric uses a friction-fit plastic insert that can be stapled onto new material. Some fusible tape was ironed onto the sides to finish those edges, and the roller at the top has strong adhesive that remains for a second use after peeling off the original material.

A fabric printer was used to produce this rendition of shades. But we’d like to see some conductive thread added for a fabric-based display that can be rolled up when not in use.

Airport Express speaker mashup

[Wei] salvaged the internals from an Airport Express that had a blown power supply. From there he built this streaming music box. The case is from an IKEA clock with the face removed. He added some decorative fabric around a grill to make an acoustically transparent front panel. Inside you’ll find the Airport guts connected to a USB charger (replaces the dead PSU) and a set of powered stereo speakers. This simple mashup looks good and frees up space in your junk-parts box.

RGB Lamp bulb replacement

Wanting to make some unique and interesting gifts for his nieces as well as improve his PCB skills and expand beyond Arduino, [Jay] has made these color changing Ikea lamps. He’s using an ATTiny2313 for the brains, a handful of RGB LEDs plus 3 warm white LEDs to keep the wife happy. you can download the schematic and PCB files if you want to reproduce this one yourself. You can see his PCB making skills have improved since the nursery room temperature monitor. We think his nieces will be pleased with their gifts.

Did that table just move?

A table and chair that can move around by themselves? What’s next, suicide boothsself-replicating robots, and Star Trek styled tablet computers? It seems that [Adam Lassy] is moving in that direction. He took this furniture from Ikea and made some neat modifications to give it mobility. Each of the four legs has wheels on them and the legs themselves rotate in unison to change the direction of travel. We could see the table as a more practical drink delivery system than the Bar2d2. It certainly would make for some great late-night pranks but the chair motors need to be silenced before that can happen.

LEDs invade coffee table crevice

That’s a lot of LEDs, and a little bit of glass cleaner. [Tobias] spiced up his IKEA coffee table by adding 6144 LEDs. This is a larger realization of SparkFun’s LED coffee table which used 64 8×8 modules. [Tobias] sourced three display boards from Sure Electronics for a total of 96 8×8 modules. These boards are addressed through a serial interface; four serial lines for each board but a shared data bus for each of the row select pins and the data/latch/clock pins.  This method uses 19 of the 20 pins on the Arduino that drives the display. After the break you can see a demonstration. If this is more than you need there’s always the 112-LED and 81-LED table projects that can produce a full color range. [Read more...]

Ikea Dioder hack

[Joseph] wrote in to tell us about his Ikea Dioder hack. The Dioder is a lighting system with a silly name from Ikea. It is basically 4 RGB LED bars that are connected to a controller that will cycle their colors in different manners. They aren’t individually addressable, and at $50 aren’t really that great of a deal for people who could build their own. [Joseph] thought that maybe, if the features could be extended, it could be a decent lighting system. He bought it and began searching. Disappointed by the lack of hacks available, he cracked it open and began brainstorming. Ultimately, he decided to interface it with his computer. He can now control it with software, so making an ambilight clone shouldn’t be too difficult.

He does mention that he thought of making 4 independent drivers so that each light bar could be a different color. We agree that this would be the next logical step, possibly even rewiring for individual access to each LED.
