Ikea Desk Lamp That Will Defend Your Lungs

November 15, 2016 by James Hobson 23 Comments

While some people may enjoy the occasional whiff of noxious smells — gasoline, axe body spray, etc — prolonged exposure to fumes is not good for your health. This goes for soldering too, isn’t it about time you added some abatement to your bench tools?

Inspired by some of the fume hoods we’ve featured before — take note, ye who art lacking projects — [Georg Sluyterman] put together his own Ikea lamp fume extractor.

The most striking feature is that it’s mounted on an Ikea desk lamp making for convenient positioning and minimal clutter. A NeoPixels strip lights up your soldering space while the PIR sensor activates the fan when it detects movement. A WeMos D1 Mini is included for WiFi connectivity but that feature still down the road a little bit. The functionality that is in place is still quite impressive; more on that after the break.

Clever Use Of PVC To Make A Standing Desk At Work

March 16, 2014 by James Hobson 35 Comments

[Daniel] and his coworker [Chris] were interested in the concept of standing desks — unfortunately, the company wasn’t about to buy them a new desk to test it out — so they decided to modify the tables themselves!

The IKEA tables they are using have three adjustable legs — just not that adjustable for standing. The challenge was to modify these tables in such a way that it can easily be reversed — they didn’t want the facilities department to get mad at them! Originally they wanted to use steel legs for structural stability, but discovered they’d have to do quite a bit of modification to the steel tubing with tools they didn’t have. So they chose PVC instead.

[Chris] had remembered seeing a hack here on heating up PVC pipe to make it malleable — try as we might we weren’t able to find what he was referring to, but a quick search on YouTube brings up lots of tutorials on how to do it.

Scratch-built Desk Adjusts So You May Sit Or Stand

May 21, 2013 by Mike Szczys 52 Comments

custom-height-adjustable-battlestation

Knowing that this desk was built from scratch is pretty impressive. But the motorized legs that raise and lower the desk to any height really puts the project over the top.

Surprisingly this started off as a computer case project. [Loren] upgraded his hardware and couldn’t find a case that would organize it the way he liked. His desk at the time had a glass top and he figured, why not build a new base for the glass which would double as a computer case? From there the project took off as his notebook sketches blossomed into computer renderings which matured into the wooden frame seen above.

Much like the machined computer desk from last December this uses motorized legs to adjust the height of the desk. These cost about $50 each, and he used four of them. If you consider the cost of purchasing a desk this size (which would not have been motorized) he’s still not breaking the bank. This battlestation is now fully functional, but he does plan to add automated control of the legs at some point. We think that means that each has an individual adjustment control which he wants to tie into one controller to rule them all.

Motorizing An IKEA SKARSTA Table

January 23, 2019 by Tom Nardi 38 Comments

We’ve been told that standing at a desk is good for you, but unless you’re some kind of highly advanced automaton you’re going to have to sit down eventually no matter what all those lifestyle magazines say. That’s where desks like the IKEA SKARSTA come in; they use a crank on the front to raise and lower the desk to whatever height your rapidly aging corporeal form is still capable of maintaining. All the health benefits of a standing desk, without that stinging sense of defeat when you later discover you hate it.

But who wants to turn a crank with their hand in 2019? Certainly not [iLLiac4], who’s spent the last few months working in conjunction with [Martin Mihálek] to add some very impressive features to IKEA’s adjustable table. Replacing the hand crank with a motorized system which can do the raising and lifting was only part of it, the project also includes a slick control panel with a digital display that shows the current table height and even allows the user to set and recall specific positions. The project is still in active development and has a few kinks to work out, but it looks exceptionally promising if you’re looking to get a very capable adjustable desk without breaking the bank.

The heart of the project is a 3D printable device which uses a low-RPM DC gear motor to turn the hex shaft where the crank would normally go. A rotary encoder is linked to the shaft of the motor by way of printed GT2 pulleys and a short length of belt, which gives the system positional information and avoids the complexity of adding limit switches to the table itself.

For controlling the motor the user is given the option between using relays or an H-Bridge PWM driver board, but in either event an Arduino Nano will be running the show. In addition to controlling the motor and reading the output of the rotary encoder, the Arduino also handles the front panel controls. This consists of a TM1637 four digit LED display originally intended for clocks, as well as six momentary contact tactile switches complete with 3D printed caps. The front panel’s simple user interface not only allows for setting and recalling three preset desk heights, but can even be used to perform the calibration routine without having to go in and hack the source code to change minimum and maximum positions.

We’ve seen all manner of hacks and modifications dealing with IKEA products, from a shelving unit converted into a vivarium to a table doing double duty as a cheap plate reverb. Whether you’re looking for meatballs or some hacking inspiration, IKEA seems to be the place to go.

Pulley Lamp Stands Up With You

October 14, 2016 by Elliot Williams 33 Comments

Standing desks are either the best thing since sliced bread, or the fastest way to make your legs tired and get you ridiculed by your coworkers in the bargain. This leads some folks to compromise and make standing desks that can be re-lowered to sitting height when you need to take a break. But now the distance from your desktop to the light source that illuminates it has changed. We can’t have that!

[John Culbertson] came up with a very elegant solution to the “problem”. He made lights that are suspended on pulleys that raise and lower with the desk itself. We’re not sure that you’re in the same situation he is, but we’re sure that you’ll agree that he did a nice job.

Besides the pulley mechanism, the light shades are a work of art. [John] clearly wanted a retro feel, so he used low-voltage lightbulbs, but augmented them with LED strips to pump out the lumens. All in all, there’s a tremendous attention to detail in the project, and it shows.

Disclaimer: your humble author is writing you this missive from a standing desk. Ours is just a regular desk put up on bricks — a temporary solution that’s become permanent. We’re always keeping our eyes out for mechanisms to make the desk convertible, but everything that we’ve seen is either overkill or ridiculously overpriced or both. It’s hard to beat 24 bricks at $0.35 apiece. Anyone have any suggestions?

Of course, with an adjustable desk come the problems of moving your lighting along with it, but [John] has solved that one for us.

IKEA BEKANT sit/stand desk with a new controller attached

LYFT: Standing Up For Better IKEA BEKANT Control

April 18, 2024 by Kristina Panos 6 Comments

The IKEA BEKANT sit/stand desk is kind of a lifesaver — even if you don’t personally go between sit and stand much, the adjustability makes sharing the desk a breeze. Sharing was the case in [Matthias]’ house during the pandemic, as he and his wife took turns using the desk. Switching between their two preferred heights quickly became annoying, so [Matthias] engineered LYFT, a replacement controller that stores up to four settings.

In addition, the new SAMD21-based controller allows them to raise and lower the desk without having to hold the button down. And finally, having a digital readout showing the position is just plain cool. As you’ll see in the manual (PDF), LYFT is as easy to set up and use as the average flat-packed product.

In order to make this work, [Matthias] had to figure out how the desk’s motors communicate out of the box, and he did so with the help of a BEKANT controller project by [Greg Cormier]. You won’t find LYFT at the blue and yellow, at least not yet; for now, you’ll have to shop Tindie or build it yourself.

Keebin’ With Kristina: The One With The Pocket Cyberdeck

March 12, 2024 by Kristina Panos 10 Comments

When you find something you love doing, you want to do it everywhere, all the time. Such is the case with [jefmer] and programming. The trouble is, there is not a single laptop or tablet out there that really deals well with direct sunlight. So, what’s a hacker to do during the day? Stay indoors and suffer?

The answer is a project like Pocket Pad. This purpose-built PDA uses a Nice! Nano and a pair of two very low-power ST7302-driven monochrome displays. They have no backlight, but they update much faster than e-paper displays. According to [jefmer], the brighter the ambient light, the more readable the displays become. What more could you want? (Besides a backlight?)

The miniature PocketType 40% is a little small for touch typing, but facilitates thumbs well. [jefmer] added those nice vinyl transfer legends and sealed them with clear nail polish.

All of the software including the keyboard scanner is written in Espruino, which is an implementation of JavaScript that targets embedded devices. Since it’s an interpreted language, [jefmer] can both write and execute programs directly on the Pocket Pad, using the bottom screen for the REPL. I’d sure like to have one of these in my pocket!
