As any content creator knows, good audio is the key to maintaining an audience. Having a high quality microphone is a start, but it’s also necessary to reduce echoes and other unwanted noise. An isolation shield is key here, and [phico] has the low down on making your own.
The build starts with an IKEA lampshade, so it’s a great excuse to head down to the flatpack store and grab yourself some Köttbullar for lunch while you’re at it (that’s meatballs for those less versed in IKEA’s cafeteria fare). This is really more of a powder-coated steel frame than a shade, perfect as the bones of an enclosure. [Phico] hacks it open with a Dremel to make room for the microphone. Cardboard soaked in wallpaper paste is then used to create a papier-mache-like shell, which is then stuffed with acoustic foam. A small opening is left to allow the narrator’s voice to reach the microphone, while blocking sound from other directions. Finally, a stocking is wrapped around the whole assembly to act as an integral anti-pop filter.

It’s a tidy build, and while it looks a bit like a boulder to some, if you encounter a room full of ovomorphs that look just like this, tiptoe right out of there. IKEA hacks are always popular, and this laser projector lamp is a great example. If you’ve got your own nifty Swedish-inspired build, make sure you let us know!
The ThisAbles project is a series of 3D-printed IKEA furniture hacks making life easier for those without full use of their bodies. Since IKEA furniture is affordable and available across most of the planet, it’s the ideal target for a project that aims to make 3D-printed improvements accessible to everyone.
These hacks fit all meanings of the word “accessible”: Available worldwide, affordable, and helping people overcome physical barriers of everyday living. ThisAbles has support of multiple organizations including IKEA Israel. In their short introductory video (embedded below the break) they explained their process to find ways to make big impacts with simple 3D-printed modifications. From bumpers protecting furniture against wheelchair damage, to handles that allow drawers to be opened without fine fingertip control. Each of these designs also fit the well-known IKEA aesthetic, including their IKEA style illustrated manuals.
The site launched with thirteen downloadable solutions, but they have ambitions for more with user feedback. There’s a form where people can submit problems they would like to see solved, or alternatively, people can submit solutions they’ve already created and wish to share with the world. Making small changes to commodity IKEA furniture, these 3D printed accessories will have far more impact on people’s lives than the average figurine trinket on Thingiverse. It’s just the latest way we can apply hacker ingenuity to help others to do everything from simple daily tasks to video gaming.

We love to hack IKEA products, marvel at Raspberry Pi creations, and bask in the glow of video projection. [Nord Projects] combined these favorite things of ours into Lantern, a name as minimalist as the IKEA lamp it uses. But the result is nearly magic.
The key component in this build is a compact laser-illuminated video projector whose image is always in focus. Lantern’s primary user interface is moving the lamp around to switch between different channels of information projected on different surfaces. It would be a hassle if the user had to refocus after every move, but the focus-free laser projector eliminates that friction.
A user physically changing the lamp’s orientation is detected by Lantern’s software via an accelerometer. Certain channels project an information overlay on top of a real world object. Rather than expecting its human user to perform precise alignment, Lantern gets feedback from a Raspberry Pi camera to position the overlay.
Speaking of software, Lantern as presented by [Nord Projects] is a showcase project under Google’s Android Things umbrella that we’ve mentioned before. But there is nothing tying the hardware directly to Google. Since the project is open source with information on Hackster.io and GitHub, the choice is yours. Build one with Google as they did, or write your own software to tie into a different infrastructure (MQTT?), or a standalone unit with no connectivity at all.

Many people got their start with 3D printing by downloading designs from Thingiverse, and some of these designs could be modified in the browser using the Thingiverse Customizer. The mechanism behind this powerful feature is OpenSCAD’s parametric design capability, which offers great flexibility but is still limited by 3D printer size. In the interest of going bigger, a team at MIT built a system to adopt parametric design idea to woodworking.
The “AutoSaw” has software and hardware components. The software side is built on web-based CAD software Onshape. First the expert user builds a flexible design with parameters that could be customized, followed by one or more end users who specify their own custom configuration.
Once the configuration is approved, the robots go to work. AutoSaw has two robotic woodworking systems: The simpler one is a Roomba mounted jigsaw to cut patterns out of flat sheets. The more complex system involves two robot arms on wheels (Kuka youBot) working with a chop saw to cut wood beams to length. These wood pieces are then assembled by the end-user using dowel pegs.
AutoSaw is a fun proof of concept and a glimpse at a potential future: One where a robotic wood shop is part of your local home improvement store’s lumber department. Ready to cut/drill/route pieces for you to take home and assemble.

Children have always liked to learn by copying the adults around them, and thus have always desired toys that emulate the tools which their older forebears use on a daily basis. [rhoalt]’s daughter wished for an oven to play with, so a trip to IKEA was in order to get started.
The build begins with the IKEA Duktig, a beautiful fun-sized oven. [rhoalt] then breaks out the hacker staple foods of 7-segment displays, swanky backlit buttons and an Arduino Nano. Through some careful handiwork, the wooden panels that make up the toy oven are drilled and routed out to fit the components.
The electronics are all used to create an oven with a digital timer, and the final effect achieved is rather nice. The glowy buttons can be used to set and reset the timer, while an LED strip inside lights up to simulate cooking. [rhoalt] shares all the construction details along with some parent-friendly tips, like taping over the buzzer to reduce the volume, and ensuring the timer is limited to 10 minutes to avoid any late-night surprises.
It’s a tidy project with a strong sense of fun, and the presentation is top-notch. Even we older, jaded hackers light up for a good glowy-buttoned project, so we’re sure [rhoalt]’s daughter loves her new toy. For more toy oven action, check out this Easy Bake converted to USB. Video after the break.

Readers who took part in the glory days of custom PC building will no doubt remember the stress of having to pick a case for their carefully-curated build. You may have wanted to lower the total cost a bit by getting a cheap case, but then you’d be stuck looking at some econo-box day in and day out. Plus, how do you post pictures online to boast about your latest build if there are no transparent windows and a lighting kit?
While some may have spent more time choosing their lighted case fans than their optical drive, [Miroslav Prašil] was surely not one of them. When he decided to build a new NAS for his home network, [Miroslav] decided he wanted to put all his money into the device’s internals, and house his build in a wooden storage crate from IKEA. While the low cost was certainly a major factor in the decision, it turns out the crate actually offers a decent amount of room for hardware components. As an added bonus, it doesn’t look completely terrible sitting out in the living room.
In a detailed series of posts on his blog, [Miroslav] walks us through the entire process of building what he has come to call the “NAScrate”. Wanting gigabit Ethernet and a real SATA controller, [Miroslav] went for the ASRock C70M1, a Mini-ITX board with integrated dual-core AMD processor. While not exactly a powerhouse, it will certainly wipe the floor with the fruit-inspired single board computers that so often dominate these types of builds.
To get his clearances worked out, [Miroslav] rendered the entire build in OnShape, which gave him enough confidence in his design to move on to actual construction. The build involves several 3D printed parts, most notably some clever hard drive mounting brackets which allow the drives to be stacked into a space-saving arrangement while still leaving room for airflow between them.
[Miroslav] deftly avoids any religious debates by leaving off his particular choice for software and operating system on his newly constructed NAS, but he does mention that something like FreeNAS would be a logical choice.
While this may be the first wooden one we’ve covered so far, home servers in general are a favorite project for hackers, from budget-friendly scratch builds all the way up to re-purposed enterprise hardware.
It used to be a must-have on any hi-fi, a pair of moving coil meters or LED bar graphs, the VU meter. Your 1980s boombox would have had them, for example. VU, for “Volume Units”, is a measure of audio level, and the fashion for its visual measure in consumer audio equipment seems now to have largely passed.
The LED bar graph VU meters were invariably driven by the LM3915, a chip that contains a resistor ladder and a stack of comparators which can drive LEDs directly. [Juvar] has taken an LM3915, and used it to drive a set of opto-isolated triacs which in turn drive a stack of appropriately coloured mains LED bulbs concealed within an Ikea Vidja lamp. The result is a huge and very bright VU meter that is as much a lighting effect as it is a measure of sound level.
He’s posted a video of the lights in action, and we’ve placed it below the break. There is a cameo appearance from his cat, and one can’t escape the feeling that it is wasted on a small room and would be at its best before a dance floor. Still, it’s a neat lighting effect and a new use for a classic integrated circuit.
