If 3D Printer, Then Custom Aluminum Extrusion Brackets

See the original posting on Hackaday

Aluminum extrusions are a boon for mechanical assemblies, but they require a stock of brackets and other hardware to be kept on hand. [mightynozzle] has decided to make things a little easier for prototyping and low-stress assemblies by creating a collection of 3D printable brackets for aluminum extrusions. 3D printing your own bracket hardware means faster prototyping, and if the assemblies don’t need the extra strength and rigidity of metal brackets you can just stick with the 3D printed versions.

The files are on Thingiverse, and include STL files of common brackets as well as an OpenSCAD script for customizing. …read more

Poor Man’s Laser Scanner Probably Won’t Shoot Your Eye Out, Kid

See the original posting on Hackaday

Yes, laser cutters that come off the slow boat from China are more affordable than ever, and with some tweaks and hacks they can turn out some decent results. But if you just want a laser lightshow that’ll draw boxes on your living room ceiling, this simple X-Y laser scanner might be a good platform to build.

Let’s say right up front that there are more than a few safety issues with [ThingEngineer]’s 3D-printed two-axis scanner. He’s well aware of these potential retina-cooking issues and duly notes that a good pair of laser safety goggles is a must and that …read more

Hangprinter Build Videos

See the original posting on Hackaday

We figure with the rise in 3D printing, it is time for a new Finagle’s law: Any part you want to print won’t fit on your print bed. There was a time when a 100 mm x 100 mm bed was common for entry-level printers. These days, more printers have beds around (200 mm)2. A hangprinter’s work area can be larger. Much larger. [Thomas Sanladerer] is building one, and has a series of videos about the build. You can see the first one below, but there are several posted, including about 11 hours of recordings of live sessions …read more

Everything coming to Netflix in January

See the original posting on The Verge

The new year is just around the corner, and that means a whole new slate of movies and TV shows to watch on your streaming service of choice will soon be on their way. Netflix will be kicking the new year off in a big way, and it comes down to four words: Tim Burton’s original Batman.

Okay, that might not be a huge slam dunk for everyone else, but I’m certainly excited about it. The service will also be adding a wide selection of new original movies, like Mike Flanagan’s thriller Before I Wake (January 5th), the Jack Black indie comedy The Polka King (January 12th), and A Futile and Stupid Gesture, the Will Forte comedy about the origins of National Lampoon (arriving on January 26th, shortly after its premiere at the 2018 Sundance Film…

All the features I’m still getting used to on the iPhone X

See the original posting on The Verge

Since the week before Thanksgiving, I’ve been using the iPhone X. Prior to that, I was using the iPhone 8 Plus, which Apple loaned me. During the busy fall reviews season, I also used the Google Pixel 2 and briefly used the Essential smartphone.

But this article isn’t a round up of these new phones or a direct comparison of all four. It’s about the iPhone X.

Some of my fellow Verge writers determined that iPhone X is “easily the best smartphone ever made.” There are a lot of things to love about the iPhone X, including its ridiculously long battery life, excellent camera (front-facing Portrait mode!), and just how fast the thing is. I can see why my co-workers found true smartphone love. I haven’t yet.

Nearly a month later, I’m still…

Better 3D Printing Through Holography

See the original posting on Hackaday

When most of us think about 3D printing, we usually think about a machine that melts plastic filament and extrudes it through a nozzle. But we all know that there are other technologies out there that range from cutting and laminating paper, to printing with molten metal or glass. Many of those are out of range for the common hacker. Probably the second most common method uses photo resin and some light source to build the layers in the resin. Researchers at Lawrence Livermore National Laboratory (LLNL) and several universities are experimenting with a new technique that exposes photo resin …read more

New trailers: Ready Player One, Annihilation, and more

See the original posting on The Verge

I haven’t seen The Last Jedi yet (I’m going Saturday night!), but I’m excited to catch it this weekend. That’s not something I would have expected two years ago: I’ve never been a big Star Wars fan, but The Force Awakens is such a perfect start to the new trilogy that it was able to change that.

What I love about The Force Awakens (and what I suspect longtime Star Wars fans dislike about it) is that it treats Star Wars as myth in order to usher a new generation into that world. The movie is built on the idea that you’ve heard about but never bought into Star Wars, and it sweeps you along with a surprising amount of humor and some wonderfully earnest characters. The very first scene in The Force Awakens even goes out of its way to make…

Are you still using an RSS reader?

See the original posting on The Verge

It’s been close to five years since Google decided to shut down Reader, the ubiquitous and beloved RSS news client. At one point, I used to do almost all my internet reading through RSS. I kept my feeds meticulously clean, poring over personal blog entries and tabbing quickly down the news, opening stories that piqued my interest. The loss of my favorite platform felt like a personal betrayal.

After Reader died, I switched to Feedly, which I’m still using today. But my relationship with it is very different. If Reader was a neat lawn, my Feedly is now an overgrown lot. I’ve got nearly 30,000 unread articles across 186 feeds, including several for websites that no longer exist — I leave some of them on the list because I’m lazy, and some…

Don’t Get Caught Up In Blockchain Hype

See the original posting on Hackaday

It’s the story of the moment, isn’t it. As the price of Bitcoin continues on its wild and crazy rollercoaster ride, everyone’s talking about cryptocurrencies, and in almost mystical terms, about blockchains. Perhaps to be a little more accurate, we should report that they are talking about The Blockchain, a single entity which it seems is now the answer to all ills.

Of course, there is no single blockchain, instead blockchain technologies form the underpinnings of the cryptocurrency boom. Since little dollar signs seem to be buzzing around in front of everyone talking about that subject, it has attracted the …read more

Digital Kiln

See the original posting on Hackaday

A kiln or foundry is too often seen as a piece of equipment which is only available if a hackspace is lucky enough to have one or individuals are dedicated enough to drop the cash for one of their own. [The Thought Emporium] thought that way until he sourced materials to make his own kiln which can also be seen after the break. It costs half the price of a commercial model not including a failed—and exploded—paint can version.

As described in the video, these furnaces are tools capable of more than just pottery and soft metal baubles. Sure, a …read more

The Smartest Air Freshener In The Room

See the original posting on Hackaday

Many automatic air fresheners are wasteful in that they either ceaselessly spritz the room, and manual ones need to be — well — manually operated. This will not do in an era of smart products, so Instructables user [IgorF2] has put together an air freshener that does more than check if you’re around before freshening things up.

The air freshener uses a NodeMCU LoLin and an MG 995 servomotor, with a NeoPixel ring acting as a status light. Be aware — when the servo is triggered there is a significant spike in current, so be sure you aren’t powering the …read more

Chrome 64 Beta Adds Sitewide Audio Muting, Pop-Up Blocker, Windows 10 HDR Video

See the original posting on Slashdot

Chrome 64 is now in beta and it has several new features over version 63. In addition to a stronger pop-up blocker and support for HDR video playback when Windows 10 is in HDR mode, Chrome 64 features sitewide audio muting to block sound when navigating to other pages within a site. 9to5Google reports: An improved pop-up blocker in Chrome 64 prevents sites with abusive experiences — like disguising links as play buttons and site controls, or transparent overlays — from opening new tabs or windows. Meanwhile, as announced in November, other security measures in Chrome will prevent malicious auto-redirects. Beginning in version 64, the browser will counter surprise redirects from third-party content embedded into pages. The browser now blocks third-party iframes unless a user has directly interacted with it. When a redirect attempt occurs, users will remain on their current page with an infobar popping up to detail the block. This version also adds a new sitewide audio muting setting. It will be accessible from the permissions dropdown by tapping the info icon or green lock in the URL bar. This version also brings support for HDR video playback when Windows 10 is in HDR mode. It requires the Windows 10 Fall Creator Update, HDR-compatible graphics card, and display. Meanwhile, on Windows, Google is currently prototyping support for an operating system’s native notification center. Other features include a new “Split view” feature available on Chrome OS. Developers will also be able to take advantage of the Resize Observer API to build responsive sites with “finger control to observe changes to sizes of elements on a page.”

Give Workshop Pencils a Flush-Mounted Home

See the original posting on Hackaday

Pencils and pens are apt to go wandering in a busy workshop if they don’t have a handy storage spot. For most of us a soup can or an old coffee mug does the trick, but for a prettier and more useful holder [Stuff I Made] has a short video demonstrating a storage unit made from an elbow fitting and a scrap piece of plywood. He cuts a plywood disk that is friction-fit into one end of the elbow, then it gets screwed into a wall making an attractively flush-mounted holder in a convenient spot.

With the right joint the …read more

Turning Saw Blades Into Throwing Stars

See the original posting on Hackaday

The holidays are nearly upon us, and if you haven’t found the perfect gift for the Mall Ninja in your life yet, this latest hack might be just what you’re looking for. On his YouTube channel, [The Nocturnal Alchemist] demonstrates how to make ninja throwing stars (shuriken) out of an old circular saw blade. One could probably argue that a circular saw itself is close enough to throwing star if your only goal is to wreck some stuff in your backyard, but with this method they’ll have that official samurai look.

To start the process, he hits both sides of …read more

Coin cell powered sea turtle research

Hacking and tinkering are always fun and games, but one just has to appreciate when all efforts are additionally aimed towards doing something good. [Nikos] sets an example by combining his interest in technology with his passion for wildlife conservation by creating a low cost and ultra-low power temperature logger — and he is using a coin cell for it.

As the founder of a sea turtle conservation project in Greece, [Nikos] enjoys building scientific instruments that help him and his team on their mission. With a goal to log the temperature every 10 minutes over a period of at …read more
