It’s not hard to drastically increase the production value in your videos by adding a camera slide to your shot — in fact, [Derek] shows us how to make a decent camera slide using parts from IKEA for less than $30.
The hack makes use of a cutting board, glider and hook accessories, a triple curtain rail, and two ceiling fixtures. The ceiling fixtures are simply used to make a mount for the curtain rail to rest on. [Derek] shows us an easy way to make the carriage with some careful drilled holes in the cutting board — he’s added a 3D printed tripod head for mounting the camera, but really you can use whatever you want.
It’s a pretty simple and easy to build rig, and the results are quite impressive — just check out the following video to see!

Some people look at IKEA LACK tables as cheap furniture. Our readers look at them as a blank canvas. [Klaas] has turned a LACK Side table into an interactive LED table featuring 144 RGB LEDs. After attending a class on WS2801 pixel strings at his student IEEE chapter, [Klaas] was inspired to design something of his own. He settled on an IKEA LACK table and started sketching. He didn’t actually have a table on hand, so he had to deduce the size from the website images and dimensions. He calculated a usable size of around 45cm, which was pretty close to the mark. After running a few tests, [Klaas] determined that a 12×12 grid of squares 35mm on a side would provide that enough resolution to play simple games. The 35mm x 35mm grid would also be small enough for the LEDS to illuminate. He used a laser cutter to cut the an interlocking grid from 3mm MDF. A base plate with 144 12mm LED holes was also cut out, and the entire assembly was glued together.
For illumination, [Klaas] settled on WS2812B LEDs, as they were cheaper than their WS2801 couterparts. The WS2812B’s also snapped easily into his 12mm holes. At this point [Klaas] actually purchased his IKEA table and proceeded to cut a huge hole in it. The grid glued right in, and some aluminum L-profile cleaned up the top edge. Driving all those LEDs would need a bit of processing power, [Klaas] chose a Teensy 3, and the well-known OctoWS2811 library. He also added a USB host shield, which allowed him to use an Xbox 360 USB game pad as his controller. For software, he created a simple Tetris clone, and ported snake from the Arduino game shield. A menu and some scrolling text ties everything together. The only thing left to add is a glass top. [Klaas] hasn’t settled on clear or diffuse glass yet. We a suggest clear to avoid hiding any details of this great build.

[Dzl] and his rather serious looking son are metal detector enthusiasts. But when they couldn’t find their store-bought metal detector earlier this summer they just went ahead and built their own. [Dzl] starts his write up with an explanation of how most oscillator based metal detectors work. This one differs by using an Arduino to read from the metal detecting coil.
The circuit starts with an oscillator that produces a signal of about 160 kHz which is constantly measured by the Arduino. When metal enters the coil it alters the frequency, which is immediately picked up the Arduino. Instead of that characteristic rising tone this rig uses a Piezo buzzer, issuing the type of clicks you’d normally associate with a Geiger counter.
The last part of the build was to find the best coil orientation. They settled on thirty turns around a metal bucket. An old Ikea lamp is the perfect form factor to host their hardware which seems to work like a charm.
This rather bulky looking wall wart is actually a computer mouse. Sure, it may cause your hand to cramp horribly if used for any length of time. But some would say it’s worth that for the hipster value of the thing.
The rather odd shape is somewhat explained by the fact that this was sourced from Ikea. After gutting the transformer found inside the plastic case he had plenty of room to work with. He drilled a hole so that the sensor from a Logitech USB optical mouse can pick up the movement of the mouse. He also got pretty creative when it came to the buttons. The two prongs of the wall plug pivot horizontally to affect the momentary press switches inside.
After the break you can see a quick demo of the project. [Alec] doesn’t consider it to be complete. He wants to make a couple of improvements which include adding weight to make it feel more like the original wall wart, and finding a way to hide the hole he drilled for the sensor.

There are a lot of hacks out there for Ikea’s Dioder LED light set. [Lambertus] wanted to create an easy and affordable ambilight while keeping the hardware modifications to a minimum. He also wanted anyone to be able to easily duplicate his work. He recently wrote in to share his successful solution.
The customizations boil down to three main steps: solder the ICSP connector wires to the test points on the Dioder PCB, connect a PIC programmer to the ICSP port (and reprogram), and attach a 5V RS-232 device to the ICSP port. The software was the most difficult part of the procedure for [Lambertus]. The PIC16F684 didn’t contain the required UART and PWM controllers, so he had to get crafty. Fortunately he’s done all the work for us, and lists the necessary .hex file he created on his site.
By adding support to boblight, his new ambilight is working with his media center very nicely. There’s a little demo video after the break.

[Victor] may be onto something when it comes to project enclosures. He’s using a picture frame to house his electronics projects. This is made especially easy by the variety of sizes you can find at Ikea. Possibly the most important dimension is to have enough frame thickness to sandwich your components between the glass and the back plate of the frame.
The project seen here is a temperature data logger. The frosted diffuser covering everything but the LCD screen and gives you a glimpse of what’s mounted to the back panel. He connected the four different protoboard components, along with a battery pack, to each other use right angle pin headers. They were then strapped to the back plate of the frame by drilling some holes through which a bit of wire was threaded. He even cut a hole to get at the socket for the temperature sensor and to attach the power input. So that he doesn’t need to open the frame to get at the data, the SD card slot is also accessible. His depth adjustment was made by adding standoffs at each corner of the frame, and replacing the metal wedges that hold the back in place.
You don’t need to limit yourself with just one. This UV exposure rig uses three Ikea frames.
Get some Pac-Man fever while sitting on this couch thanks to the arcade rig built inside of the coffee table. The controls are a bit more sparse than more dedicated MAME rigs, but you should still be able to play most of the classics with four buttons and a joystick. After all, you need to reserve some room to put your feet up when you’re not gaming.
[Manny Flores] started the project with a Lack table from Ikea. The top is anything but solid. After tracing the outline of his LCD screen and cutting through the surface he discovered this is more of a beefed of cardboard than it is wood. The honeycomb of paperboard inside the surface of the table makes it really easy to clear out some space. In fact, when it came time to add the arcade buttons he just used a utility knife to cut the openings. Inside you’ll find a Raspberry Pi which interfaces with the buttons and joystick via an iPac USB controller board. A set of powered speakers mounted on the underside complete the design.
