IKEA Lantern Houses Full-Featured Weather Station

From plain and utilitarian to the sleek and professional, there are a lot of ways to build a multifunction weather station. We’d thought we’d seen it all here, but building a weather station into an IKEA lantern is a pretty unique presentation.

There’s  an active community over at ikeahackers.net, and the variety of IKEA hacks they’ve come up with is pretty astounding. For this weather hack, [Richard Stevens] chose the Borrby, a $15 candle lantern. While it doesn’t exactly scream “weather station”, the form factor makes sense – plenty of room for electronics, easily replaced windows, and a nice cupola for mounting extra displays. [Richard]’s build includes a barometer, a hygrometer, and a thermometer, along with graphing displays for trends and historical data. There’s also an alarm clock and a rear panel bristling with more connectors and switches than an 80s-era HP oscilloscope. The wiring is admittedly “rats-nest style”, but as you can see in the video after the break, it works pretty well and looks good too.

Ikea Projection Lamp Makeover Adds LED Matrix and Raspberry Pi Zero

If you’re like us, it’s hard to walk through an Ikea without mentally hacking everything there into something else. The salad bowl? Parabolic antenna. Drawer slides? Linear motion rails. Storage containers? Etching tank. We admit that we still haven’t figured out what to do with that 1,000-pack of tea lights.

[Alain Mauer] pulled off an Ikea hack that we’ve always dreamed about. In particular, he took the Sprida projector lamp and wedged an 8×8 LED matrix and Raspberry Pi Zero into it.

The lamp in question is essentially a slide projector for kids. Before [Alain] got to it, it had an LED in the back, a mount for a slide in the middle, and a focusing lens on the front. His mod is simplicity itself: remove the LED and transparency, and place the LED matrix in the focal plane where the slide used to be. Reverse images on the LED in software to compensate for the lens, and you’re done.

The video says “Raspberry Pi Zero with WiFi” and the project title promises “IoT”, but we don’t see the WiFi in the build. We’re guessing that [Alain] will get around to it — it’s easily doable. (Doh! There’s a tiny USB WiFi dongle providing the obligatory wireless connection.) Anyway, the point is the projection, and we love it, and we’d be lying if we said it didn’t make us think about RGB matrices.

Fully Printed CNC On an IKEA Table

It seems that many 3D printer owners just aren’t getting the same buzz they used to off their 3D printers, and are taking steps to procure heavier machines. And making them in their home laboratories with, you guessed it, their 3D printers.

Following the pattern, [Michael Reitter], designed a 3D printable CNC around a IKEA MALM table. In order to span the length of the table for his X axis, he came up with a very cool looking truss assembly. The linear rails rest on top of the truss, and a carriage with the Z axis rides on the assembly. The truss has enough space in the center of it to neatly house some of the wiring. The Y-xis mounts on the side of the table.

Overall the mechanical design looks pretty solid for what it is, with all the rails taking their moments in the right orientation. We also like the work-piece hold downs that slide along the edge of the table. It even has a vacuum attachment that comes in right at the milling bit.

We’re not certain how much plastic this build takes, but it looks to be a lot. Monetarily, it will probably weigh in at a bit more than some other options. As many in the 3D printing world are discovering, sometimes there’s no reason not to leverage more mature industrial processes for lower cost large gains in accuracy and strength. Though, it’s pretty clear that one of the design goals of this project was to see how much one can get away with just a 3D printer, and we certainly can’t deny the appealing aesthetic of this CNC.

Video of it in action after the break.

Debug An IKEA Lamp Hack, Win A Lamp Controller

[Limpkin], aka Hackaday alum [Mathieu Stephan], is at it again, converting an IKEA lamp into a visual wake-up light. He wants to build an alarm that can be remotely triggered, He’s basing this project around a combination of an ESP8266 that handles the communication and timing, and a pile of 10-watt RGB LEDs. However, he is having a problem: every time he initializes the PWM (pulse width modulation) signalling that will control the level of the LEDs, his ESP8266 dev board reboots. So, he’s offering an interesting bounty for the person who finds the issue: figure it out and he will send you the lamp. Well, the PCB and components, anyway: you’ll have to add your own IKEA lamp. It’s an interesting approach to debugging a hardware problem, so feel free to take a look. The full hardware and software details are on his GitHub repository.

Flat Pack Elastic Band Lamp is a Thing of Beauty

[Matt] was looking for a project for his senior industrial design studio at Wentworth Institute of Technology. He ended up designing a clever lamp that can be flat packed. [Matt] started by drawing out designs on paper. He really liked the idea of combining curves with straight lines, but he wanted to translate his two-dimensional drawings into a three-dimensional shape.

zOz0ys6 - ImgurHaving access to a laser cutter made the job much easier than it could have been and allowed [Matt] to go through many designs for the lamp frame. The two main pieces were cut from acrylic and include mounting pegs for the elastic bands. The two plastic pieces are designed to slot together, forming a sort of diamond shape.

The final version of the lamp required that the elastic bands had holes punched in them for mounting. The holes were placed over the small pegs to keep the bands in place. [Matt] used 3/4″ industrial elastic bands for this project. He then used a 120V 15W candelabra light bulb to illuminate the lamp. The final design is not only beautiful, but it can be flat packed and manufactured inexpensively.

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.
