Absolute Overkill IKEA Lampan Lamp Hack

Sometimes too much overkill isn’t enough. [Jesus Echavarria] hacked an IKEA Lampan light for his daughter to add color LEDs, a timer, Bluetooth control over the hue, and a local override knob. The result: a $5 lamp with at least $50 of added awesomeness. Let’s have a look at the latter.

The whole lamp system is based around a PIC microcontroller and WS2811 LEDs for the color light show. Since the lamp was already built to run a 40W lightbulb, and [Jesus] wanted to retain that functionality, he added an SSR to the build. Yeah, it’s rated for 5,000W, but it’s what he had on hand.

Top-ElementsNext comes the low-voltage power supply. [Jesus] needed 5V for the PIC, and used the guts from a cheap USB charger as a quick and dirty 5V converter — a nice hack. To power the HC-05 Bluetooth module, which requires 3.3V, he wired up a low-dropout voltage regulator to the 5V line. A level-converter IC (74LVC07) gets the logic voltage levels straight between the two.

A fuse for the high-voltage power line, screw-terminal connectors all around, and a potentiometer for manual override round out the hardware build.

On the software side, [Jesus] set up the knob to turn on and off the built-in lamp as well as control the colors of the LED ring. That’s a nice touch for when his daughter wants to change the lamp’s color, but doesn’t want to go find her cellphone. But when she does, the SPP Pro app sets the colors by sending pre-programmed serial commands over Bluetooth to the PIC in the lamp.

All in all, a nice build, well-documented, and with enough rough edges that none of you out there can say it’s not a hack. Nice job [Jesus]! We can’t wait to see what he does next… robot lamp anyone?

20 MPH IKEA Poäng Chair With Aerospace-Inspired Control Panel

Spending time at work sitting on the same drab chair can get boring after a while, even if you’re lucky to use a comfortable recliner. If you want to win the Office Olympics, you need something with a bit of pep. [StuffAndyMakes] wanted to build a completely ridiculous motorized office chair. A couple of years in the making, and he’s ready to unleash the 20 MPH IKEA Poäng chair with aerospace-inspired control panel!

The OfficeChairiot MkII, as he has christened it aptly,  is a motorized IKEA Poäng comfy chair. It uses off-the-shelf scooter parts to roll around : Batteries, motors, chains, sprockets, tires, axles, and  bearings. The OfficeChairiot MkII is basically three main parts – the Chassis, the Control Panel and the comfy chair. One of the main parts of the chassis is the motor controller  – The Dimension Engineering Sabertooth 2×60 motor controller – which is also used in beefy battlebots. It’s capable of carrying 1,000 lbs. of cargo and can feed the drive system up to 60 amps per motor channel .

The brain on the chassis is an Arduino Mega which can be controlled via a hand held remote. The Mega also receives data from various sensors for motor temperature, power wire temperature, ambient air temperature, wheel RPM’s, Accelerometer’s, seat occupancy and GPS data. The firmware is designed to ensure safety. The hand held remote needs to ping the on-board Arduino twice a second. If it doesn’t hear from the Remote for whatever reason, the unit stops and turns off the lights.

The Control Panel is one crazy collection of switches, buttons, displays, a missile switch, a master key switch – in all over 30 switches and buttons. All of the devices on the panel are controlled via a second Arduino Mega, helped by a custom multiplexer board to help connect the large number of devices.

Here are a few more features the OfficeChairiot MkII boasts of :

  • 1.5 Horsepower from two 500W scooter motors
  • 20W stereo and MP3 sound effects
  • Weapons sounds, 15 different fart sounds, car alarm, horns, etc.
  • All LED lighting: Headlights, turn signals, 88 undercarriage RGB LEDs
  • Plenty of homemade PCB’s
  • Custom built aluminum body panels (with help from Local Motors, the people behind the 3D printed car)

Aside from the handcrafted wood chassis and circuits boards and firmware, it’s all off-the-shelf stuff. [StuffAndyMakes] plans on open-sourcing the schematics, C++ code and CAD drawings – so post some comments below to motivate him to do so soon. We’d sure like to see a few more of these being built, so that Office Chair racing becomes a competitive sport. Check out the video after the break.

Internet Knows Your Every Move Thanks to IKEA and ESP8266

[terenceang] got his feet wet with the ESP8266 WiFi module by hacking up an IKEA Molgan PIR light. The stock PIR light simply lights when motion is detected. [terenceang] added some extra functionality to it by making it send notifications to his phone as well.

The default configuration of the stock PIR light was to only work at night. This is done with a photo diode. It was removed to make it work in daylight, along with several other components. He removed a handful of current limiting resistors to disable the hi output LEDs. One was preserved as a visual indicator. The onboard voltage regulator didn’t supply enough current for the ESP8266. [terenceang] used some electronic wizardry and was able to solve the problem with an opto-coupler.

The one thing he would change is moving from battery to mains power, as expected battery life is less than two weeks.Schematics, source code and tons of great pictures are available on his blog. If you want to give it a try but need a crash course check out the recent news that the Arduino IDE works with ESP8266, or give direct programming a try.

Shower Occupancy Sensor Keeps Peace/Eliminates Odor at the Office

When the first two prototype ingredients listed are paperclips and Post-it notes you know it’s going to be good. The problem: one shower stall at work with numerous co-workers who bike to the office. The solution: a occupancy monitor that is smart enough to know that someone is actually in the room. You know what we’re talking about, a sensor that knows more than whether the door is open or closed. [James] got wise and built a sensor to monitor whether the door is bolted or not. We think this method is far superior to motion-based systems.

This uber-smart sensor is simply a pair of paperclips anchored on a rolled Post-it note substrate and shoved in the receiver on the door jamb. When the bolt is locked from the inside it pushes the paperclips together completing the simple circuit. This is monitored by a Spark Core but will work with just about any monitoring system you can devise. What we’re trying to figure out is how to ruggedize the paper-clip hack which we can’t think will perform well for very long. It looks like there’s room to bore out a bit more inside the receiver hole. Perhaps leaf switch with a 3D printed mounting bracket?

Oh, and kudos on the Ikea food storage container for the enclosure. That’s one of our favorite tricks for hacks which are installed for the long-run.

Basic IKEA Wall Light Turned Smart and Colorful!

WallLight-DSO

[Daniel Grießhaber] just finished his latest electronics project and we love it. He’s taken a cheap IKEA wall/ceiling light and completely revamped it with RGB LEDs and intelligent control!

The light he used is called the LOCK, and is a mere 1.79€ or about $4 USD. It has lots of room inside and a nice frosted glass dish which results in some excellent color diffusion. He’s designed a nice big circular PCB to mount inside off of the original mounting points. To do this, he used Eagle software to create the circuit and his trusty desktop CNC to mill out the pattern.

To control the lights he used an old ATMega8 board he had lying around, with the Arduino IDE and WS2812 Library. He’s outlined all the parts, diagrams and program sketches you’ll need to make your own over on GitHub.

Unfortunately the LEDs aren’t quite as bright as he hoped so it can’t be used to replace a regular room light — instead he plans on turning this project into sunrise timing light in one of the bedrooms — still pretty cool!

Koch Lamp is 3D Printed with a Twist

Koch Lamp

[repkid] didn’t set out to build a lamp, but that’s what he ended up with, and what a lamp he built. If the above-pictured shapes look familiar, it’s because you can’t visit Thingiverse without tripping over one of several designs, all based on a fractal better known as the Koch snowflake. Typically, however, these models are intended as vases, but [repkid] saw an opportunity to bring a couple of them together as a housing for his lighting fixture.

Tinkering with an old IKEA dioder wasn’t enough of a challenge, so [repkid] fired up his 3D printer and churned out three smaller Koch vases to serve as “bulbs” for the lamp. Inside, he affixed each LED strip to a laser-cut acrylic housing with clear tape. The three bulbs attach around a wooden base, which also holds a larger, central Koch print at its center. The base also contains a PICAXE 14M2 controller to run the dioder while collecting input from an attached wireless receiver. The final component is a custom control box—comprised of both 3D-printed and laser-cut parts—to provide a 3-dial remote. A simple spin communicates the red, green, and blue values through another PICAXE controller to the transmitter. Swing by his site for a detailed build log and an assortment of progress pictures.

 

MacGyver Made IKEA Camera Slider

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!
