Disappearing kitchen island

[Tim Thaler] has been redoing his home, adding some fancy automation here and there. But when it came to the kitchen, he went all-out by installing an iPhone controlled disappearing island. In the video clip after the break you can see [Tim] dial up some extra counter and storage space from his smart phone. One click causes it to slowly rise from the depths, shedding the carpet tiles as it goes.

Directly beneath the kitchen is an unfinished storage room. [Tim] framed a hole in the floor above, and sourced a used scissor lift for about $380 to do the heavy lifting. It operates smoothly and isn’t all that loud. It sure makes for an interesting feature if he ever decides to sell the place.

We thought it was a nice touch that the storage room hiding the mechanical parts of the hack has a hidden entrance. You must travel through the billiards room in the basement to access it, turning the ball rack to unlatch the entrance.

Dimming control for an Ikea solar desk lamp

[Frank] decided to augment his desk lamp’s features by adding dimming controls (translated). Since the light source is a triad of LEDs the best method of dimming their intensity is to use Pulse Width Modulation. That’s the method that he went with, and luckily the SUNNAN lamp from Ikea which he’s using as the donor for the project has just enough room to squeeze in the parts necessary for this hack.

You need two main bits to use PWM with a lamp like this; a microcontroller (or possibly a timer chip like the 555) and a transistor to protect that chip from the current necessary to run the LEDs at full brightness. [Frank] went with an ATtiny13 and a 2N2222 transistor, both quite common and very inexpensive (you can even pull the microcontroller from a light bulb if you know where to look). Two buttons were added to the top of the lamp base which allow for up and down controls. There’s even an SOS function which is triggered by pressing both buttons at the same time. [Frank's] happy to show off the completed project in the clip after the break.

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.
