FlyingCam Is A Sweet DIY Webcam On A Stick

March 12, 2025 by 5 Comments

Imagine you want to monitor a pot on the stove to see if it’s boiling over for just a few minutes, but you don’t want to have a dedicated permanent IP webcam solution in your kitchen. [Sebastian Duell]’s FlyingCam hijacks an IKEA lamp gooseneck to become something you never knew you needed: a wireless camera for short-term random remote observation. It’s a beautiful combination of 3D printing and commercial device re-use, and when paired with his DIY wireless screen, it’s a complete solution.

The guts of this project aren’t critical, or expensive. It’s built around one of those ESP32 single-board webcams, with an added fan, battery pack, antenna, and a power switch. You turn it on, and the AP in the ESP32 fires up, or optionally connects to your network. Point the camera at your target and you’re set, at least if you want to sit by your computer. But [Sebastian] also designed a nice simple remote screen, so you can keep tabs on your spaghetti wherever you roam around the house.

We love the attention to keeping the design simple here, both in form and in function. It’s a one-task device, so it’s important that it be extremely easy to use, and it’s hard to beat just pointing the thing and turning on a switch. And it doesn’t hurt that it’s good looking to boot.

IKEA stuff is cheap and cheerful, but often it’s missing just that one functionality that we want. What good is an air-quality sensor without MQTT logging capability, for instance? Or a standing desk that can’t remember set heights? Get hacking!

“Some Assembly Required” Makes Us Love Things More

March 2, 2025 by 36 Comments

For the maker looking to turn their project into a business, trying to price your widget can be a bit of a conundrum. You want to share your widget with the world without going broke in the process. What if you could achieve both, letting the end user finish assembly? [PDF]

While over a decade has passed since Harvard Business School released this study on what they dub “The IKEA Effect,” we suspect that most of it will still be relevant given the slow pace of human behavior change. In short, when you make someone become part of the process of manufacturing or assembling their stuff, it makes them value it more highly than if it was already all put together in the box.

Interestingly, the researchers found “that consumers believe that their self-made products rival those of experts,” and that this is true regardless of whether these people consider themselves to be DIY enthusiasts or not. This only holds if the person is successful though, so it’s critical to have good instructions. If you have a mass market item in the works, you probably don’t want to require someone with no experience to solder something, but as IKEA has shown, nearly anybody can handle some hex screws and Allen wrenches.

If you’re looking for more advice on how to get your invention in people’s hands, how about this Supercon talk by Carrie Sundra about manufacturing on a shoestring budget or this video from Simone Giertz on her experiences with manufacturing from idea to finished product. You might want to steer clear of people promising patents for pennies on commercials, though.

A Look Inside IKEA’s Vallhorn Motion Sensor Teardown

December 7, 2024 by 25 Comments

A good source of hackable home automation parts has come for a while in the form of inexpensive modules offered by large retailers such as Lidl, or IKEA. They’re readily available and easy to play with, they work with open source hubs, so what’s not to like! As an example, [Circuit Valley] has an IKEA Vallhorn motion sensor for a teardown, it’s as you might expect, a passive infrared sensor (PIR) sensor coupled with a Zigbee interface.

Inside the ultrasonic welded case is a small PCB and a Fresnel lens on the inside of the top cover, and a small PCB for the electronics. We applaud the use of a Swiss Army knife can opener as a spudger. The interesting part comes in identifying the individual components: the Silicon Labs EFR32MG21 SoC is easy enough, but another mystery 8-pin chip is more elusive. The part number suggests an Analog Devices op-amp for signal conditioning the PIR output, but the pinout seems not to support it and from here we think it’s too expensive a part for a budget item like this.

There’s a handy header for talking to the SoC, which we’d love to report is open and ready to be hacked, but we’re not getting too optimistic. Even if not hackable though, we’re guessing many of you find uses for these things. Continue reading “A Look Inside IKEA’s Vallhorn Motion Sensor Teardown” →

IKEA BEKANT sit/stand desk with a new controller attached

LYFT: Standing Up For Better IKEA BEKANT Control

April 18, 2024 by 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.

IKEA’s Billy Bookshelf Is A Useful 3D Printing Enclosure

August 29, 2023 by 49 Comments

The results from your 3D printer may be improved if you use a dedicated enclosure for the job. This is particularly helpful for printing certain materials which are more sensitive to cold drafts or other thermal disruptions to the working area.  If you want an elegant solution to the problem, consider getting yourself an IKEA Billy bookshelf, says [wavlew].

The Billy makes a remarkably elegant 3D printing workstation, overall. It’s got a nifty slide-out drawer that makes a perfect mounting point for a 3D printer. It lets you slide out the printer for maintenance, using the controls, or extracting finished prints. It also naturally features plenty of storage for your filament, tools, and other accoutrements. When it comes to the business of actually printing though, you just slide the printer inside and shut the door. Its thermal and noise isolating performance can also be further improved by adding a silicone door seal.

We love this idea. Too often, 3D printers are left chugging away on messy desks, where they’re subject to blasts from AC vents and other disruptions. Having everything tidily tucked away in a cupboard neatens things significantly, and could also prove helpful if you pursue fume extraction, too.

If you’ve identified any other nifty maker applications for IKEA furniture, be sure to let us know!

IKEA LACK Table Becomes Extremely Affordable DIY Copy Stand

June 16, 2023 by 14 Comments

A copy stand is a tool used to capture images of photos, artwork, books, and things of a similar nature. It holds a camera perpendicular to a large and flat surface, upon which the subject rests.

A threaded rod provides effective vertical adjustment.

They are handy, but there’s no need to spend a lot when [BlandPasta]’s DIY copy stand based on a cheap IKEA LACK table can be turned into an economical afternoon project with the help of simple hardware and a few 3D printed parts.

The main structure comes from a mixture of parts from two LACK tables: one small and one normal-sized. A tabletop is used as the bed, and the square legs make up the structural parts with the help of some printed pieces. A threaded rod combined with some captive hardware provides a way to adjust the camera up and down with a crank, while one can manually slide the horizontal camera mount as needed to frame the subject appropriately.

This is a clever remix of IKEA parts, and the somewhat matte white finish of the LACK complements photography well. Adding some DIY LED lighting is about all it takes to get a perfectly serviceable copy stand that won’t break the bank.

A Lightweight Smart Home Server

June 6, 2023 by 31 Comments

Working towards automating a few things in a home often seems simple on the surface, but it’s easy for these projects to snowball into dozens of sensors and various servos, switches, and cameras strewn about one’s living space. The same sort of feature creep sneaks into some of the more popular self-hosted home server platforms as well, with things like openHAB requiring so much computing power that they barely function on something like a Raspberry Pi. [Paulo] thought there should be a more lightweight way of tackling a project like this, and set about building his own smart home server with help from some interesting software.

The project is based around the Dirigera hub from Ikea, partially because [Paulo] is planning to use other smart home devices from Ikea as he can easily find them where he is, and also because these devices tend to use Zigbee, a non-proprietary communications standard. This means that if he ever wants to swap out the hub for another one in the future, it won’t be difficult to do. From here the major hurdle is that using the default software from these devices is fairly limiting, so [Paulo] reached for a Raspbee 2 Zigbee gateway for use with a Raspberry Pi and an extremely lightweight and customizable web server called Mako to make this happen. Using Lua as the high-level language to tie everything together he was able to easily deploy the server to control the Ikea hub and devices and automate them in any way he sees fit.

While it is true that software like openHAB and others already exists to do virtually any home automation task that could be imagined, if you’re looking to do something with a bare minimum of computing power something like [Paulo]’s solution is likely going to be the fastest and most reliable method of getting a few things automated around the home. If you’re looking for something completely open source and built from the ground up, though, we have seen a few alternative smart home solutions like this one which don’t rely on any proprietary hardware or software, but do take a little bit more effort on the user’s part.
