Five bucks will buy you a STRÅLA lamp from Ikea. It’s a battery operated hanging lamp that pipes the light out through multiple branches of fiber optic bundles. But you’ll only get white out of this, which is pretty boring. [Boris] decided to swap out the stock LED for an RGB unit and drive it with an Arduino.
The lamp nucleus is just a couple of pieces of plastic which can be popped apart to reveal the shard of PCB hosting one LED. The body of that diode is flat on the top, and [Boris] filed down his replacement to match the form factor. There are only two conductors in the wire that runs between that PCB and the battery pack, so he replaced them with four conductors (R,G,B, and GND). His prototype uses the Arduino’s PWM capabilities to control the colors, but [Boris] recommends transitioning to a simple chip like a PIC 12F675 or one of the smaller ATtiny microcontrollers after you’ve got the bugs worked out.
See how this turned out in the clip after the break.

[Jeremy Walworth] has been dumpster diving again. He noticed that his neighbor had a bucked of nice-looking wood out at the curb for garbage collection. He inquired about it and learned that it was an Ikea bed that had broken, and that the original hardware was still there in a separate bag. He dragged it to his lair and built this wine rack out of the parts.
The reused rails and hardware provide five shelves for the bottles. [Jeremy] wanted each vessel to stay in place if the shelf wasn’t full, so he grabbed a piece of mill work from the home store and cut dividers which were glued in place. Now he’s able to show off up to sixty bottles for just a couple of bucks in material expense.
It seems like Ikea is able to sell furniture for less than the cost of the materials sourced locally. We think this is a fantastic way to find parts for your own hacks, as the components that break can often be cut down to undamaged pieces. We also make sure to check the As-Is section on each visit for the ‘leftovers’ that are usually sold for pennies. Who know’s maybe you’ll find the parts you need to build a camera mount for documenting projects.
[Phillip] and the crew at Voltaic Systems took a look at the Sunnan solar powered desk lamp from IKEA a while back, and while they thought it was pretty useful, there were definitely some things they wanted to change.
First on their list of revisions was to increase the capacity of the stock battery pack. Taking the lamp apart and unscrewing the pack’s lid revealed a set of 3 AA cells, which they swapped out for higher-capacity models with more than double the watt-hour rating.
A beefed up battery is a good start, but the lamp’s tiny solar panel has no hope of topping off the batteries outside of Death Valley. To ensure that they get a nice full charge, a small jack was wired into to the battery pack, allowing the group to connect any size external solar panel they pleased.
Finally, [Phillip] and Co. wanted the ability to charge an iPad2 from the lamp’s battery pack. They hacked in a small USB connector and a slightly modified MintyBoost board to provide a little extra juice to their tablet.
While they are still testing the modifications, they say that everything is working nicely, citing that the extra battery capacity and charging abilities are a great addition.
Hackaday reader [chrysn] picked up a 3-button RGB model DIODER light from IKEA and thought he might as well take it apart to see what he could do with it. Having seen several DIODER hacks featured here, he knew it was easily hackable, but he didn’t want to simply rehash what other had already done.
All of the DIODER hacks we have come across thus far incorporate some sort of AVR chip or add-on board to expand its capabilities. [chrysn] saw that the controller already had a PIC16F684 inside, and thought that installing his own firmware onto the existing hardware would be a far more simple solution. He installed a small programming cable onto the DIODER’s control board, and using his PICkit2 programmer, flashed the chip with a custom firmware image.
His modifications worked great, and [chrysn] says that there is plenty potential in the existing hardware to have all sorts of fun with it. Even so, he notes that there are several AVR-flavored drop-in replacements that can be used if that happens to be your microcontroller family of choice.
Panning time lapse photographs always look pretty cool, but there’s that whole “making a panning time lapse” rig that gets in the way of all the fun. [Getawaymoments] put together a tutorial quite a while ago showing how to use Ikea egg timers as cheap and dispensable panning units, and has updated his instructions with a pair of refreshed designs.
He stumbled upon two new egg timers at Ikea, the Stam and Ordning, which sell for $1.99 and $5.99 respectively. The Stam is a small plastic model that can be fitted with a set screw, to which most cameras can be mounted. A small bushing can also be installed in the timer’s plastic base, allowing it to be mounted on any standard tripod.
The Ordning is a beefier unit capable of withstanding more abuse than its plastic brethren, hence the larger price tag. A few minutes on the drill press makes room for a metal bushing, allowing the Ordning to be installed on any tripod as well.
The hack isn’t high tech, but we’re impressed with the results he was able to get with these simple kitchen timers. For the cost and time required to build them, they are sure to give most other panning rigs a run for the money.

Cable management can really be an eyesore, but a little creative camouflage and you can have a cellphone charging station that also serves as decoration.
[Kitesurfer] wanted to use one of the cubbyholes in his new Ikea book shelf for charging but wasn’t keen on the rat’s nest of wires that would go along with it. Also not wanting to take on the challenge of wireless charging he hit the As-Is section of the home furnishing giant and grabbed a leftover board that matched the same finish as the cabinetry. It now serves as a false-back for the charging center behind which a power strip and wall-warts hide.
This covers up the problem, but a blank white box filled with the business end of the charging wires isn’t a whole to better. As with a magic show, the trick is in redirection. [Kitesurfer] cut a hole in the false-back and added the guts of a digital picture frame. Right now he’s got it scrolling through different charging icons, but it’s easy enough to change up the slide-show if he gets tired of them. We’d love to see a subsequent hack that lets the picture frame access the photos on your phone via Bluetooth.
ArduinoArts is animating an inexpensive Ikea lamp as a contest entry. Seeed Studio’s Toy Hacking Contest calls for the competitors to work their magic using the Grove Toy Kit, which is an extensible sensor connection system for the Arduino. Most of the items in the kit were used to add interactivity to the lamp. Check out the video after the break to see the motion that two servos provide. The lamp can move its shade back and forth as if shaking its head, and the whole arm assembly can rotate in relation to the base. The sensors detect when you’ve repositioned the lamp head and the device will yell at you if it doesn’t appreciate its new pose. It also reacts to noise and motion, switching on the LED that replaces the original bulb in both cases, and asking: “Are you Sarah Connor” when motion is detected. These basic modifications really make for some fun animatronic behavior.
