Cloning Knobs For Vintage Testing Equipment

See the original posting on Hackaday

Knobs! Shiny candy-colored knobs! The last stand of skeuomorphism is smart light switches! Everyone loves knobs, but when you’re dealing with vintage equipment with a missing knob, the odds of replacing it are slim to none. That’s what happened to [Wesley Treat] when he picked up a vintage Philco tube tester. The tester looked great, but a single knob for a rotary switch was missing. What to do? Clone some knobs! You only need some resin and a little bit of silicone.

The process of copying little bits of plastic or bakelite is fairly standard and well-tread territory. Go to …read more

Epsom Salts Restores Lead Acid Battery

See the original posting on Hackaday

Despite a lot of advances in battery technology, lead acid batteries are still used in many applications due to cost and their ability to provide a lot of surge current. But they don’t last forever. However, [AvE] shows that in some cases a failed battery can be restored with — of all things — epsom salts. If it makes you feel funny to use the stuff grandpa soaks in when he has a backache, you can call it magnesium sulfate.

You can find a complete explanation in the video below (which includes [AvE’s] very colorful language), but fundamentally, the magnesium …read more

Strobe For Wood Turning Makes Inspection Easy

See the original posting on Hackaday

The lathe is a simple enough tool to understand, but requires much practice to truly master. During the turning process, it’s often necessary to inspect the workpiece. This generally necessitates stopping the lathe, waiting for everything to spin down, and then starting again. This can be a major time sink when added up across the full scope of a project. However, the magic of strobes can help.

The basics of [Darcy]’s project will be familiar to any hacker who has worked with rotating machinery before. The rotational speed of the lathe is measured, in this case using a reed switch …read more

Always Have A Square to Spare

See the original posting on Hackaday

Some aspects of humanity affect all of us at some point in our lives. Whether it’s getting caught in the rain without an umbrella, getting a flat tire on the way to work, or upgrading a Linux package which somehow breaks the entire installation, some experiences are truly universal. Among these is pulling a few squares of toilet paper off the roll, only to have the entire roll unravel with an overly aggressive pull. It’s possible to employ a little technology so that none of us have to go through this hassle again, though.

[William Holden] and [Eric Strebel] have …read more

MIDI Association Announces MIDI 2.0 Prototyping

See the original posting on Hackaday

MIDI was introduced at the 1983 NAMM show as a means to connect various electronic instruments together. Since then, our favorite five-pin DIN has been stuffed into Radio Shack keyboards, MPCs, synths, eurorack modules, and DAWs. The standard basically hasn’t changed. Sure, we have MIDI SysEx messages to configure individual components of a MIDI setup, but at its core, MIDI hasn’t changed since it was designed as a current-loop serial protocol for 8-bit microcontrollers running at 1 MHz.

Now, ahead of the 2019 NAMM show, the MIDI Manufacturers Association (MMA) in conjunction with AMEI, Japan’s MIDI Association, are announcing MIDI …read more

Somewhere Down in Africa Toto is Playing on Loop

See the original posting on Hackaday

Amidst the vast expanse of sand dunes in the Namib desert, there now exists a sound installation dedicated to pouring out the 1982 soft rock classic “Africa” by Toto. Six speakers connected to an MP3 player all powered by a few solar powered USB battery packs, and it is literally located somewhere down in Africa (see lyrics). The whole project, known as TOTO FOREVER, was the creation of film director [Max Siedentopf] who himself grew up in Namibia.

“I set up a sound installation which pays tribute to probably the most popular song of the last four decades…and the installation

Leaked image shows off three variants for the Samsung Galaxy S10 lineup

See the original posting on The Verge

Samsung will hold its next Unpacked event next month, where it’s expected to show off a “fully functional” version of its foldable phone, along with the next iteration of its Galaxy lineup, Galaxy S10. A new leaked image from Evan Blass shows off three versions of the phone, the S10E, the S10, and the S10+.

There have been rumors floating around since last fall that the S10 would come in three variants: the S10 and S10+ with a curved OLED screen, hole-punch selfie camera, and in-display fingerprint scanners, with a third (presumably the S10E), serving as a cheaper edition without all the bells and whistles. The company is also rumored to have been in discussions with Verizon to bring a 5G version of the phone to the US. A leak from…

Apple is once again selling its iPhone SE — for now

See the original posting on The Verge

Last September, Apple officially stopped selling its iPhone X, iPhone SE, and iPhone 6s models, following the release of the iPhone XS and XR. This weekend, MacRumors noticed that Apple has quietly begun to sell the iPhone SE once again in its clearance section.

The 2016-era phone is available in 32GB and 128GB sizes, with $100 and $150 knocked off the price, respectively. The phones are available in space gray, rose gold, gold, and silver colors.

It doesn’t appear that Apple has made the iPhone X or iPhone 6s for sale once again, but if you’ve been missing a decent phone with a headphone jack, this might be the time to pick one up.

Fortnite’s floating sphere exploded, leaving the island covered in snow and zombies

See the original posting on The Verge

Fortnite’s latest mystery is finally starting to unravel. Not long ago a floating sphere made of ice appeared in the game, leaving many players to wonder just what was going on. Now we have an answer, sort of: it exploded and a mysterious figure inside called the Ice King created a massive storm, which covered the entire island in snow.

It was a dramatic moment that included a towering, ghostly apparition appearing around Polar Peak, which kicked off the storm. In addition to the shift in weather, there are now ice monsters in the game — called ice fiends — which spawn from glowing blue stones scattered across the map. The new creatures also come with a new set of challenges where players can earn wintery gear and other bonuses.

Automate Your Home From the Clearance Rack

See the original posting on Hackaday

The month or so after the holidays have always been a great time to pick up some interesting gadgets on steep clearance, but with decorations and lights becoming increasingly complex over the last few years, the “Christmas Clearance” rack is an absolute must see for enterprising hackers. You might just luck out like [ModernHam] and find a couple packs of these dirt cheap wireless light controllers, which can fairly easily be hacked into the start of a home automation system with little more than the Raspberry Pi and a short length of wire.

In the video after the break, [ModernHam] …read more

11 new trailers you should watch this week

See the original posting on The Verge

I finally got around to watching Roma the other week. It’s a fascinating film, telling its story in a way that few others do — not quite through the intimate portrait of one character, but through a world of contrasts and colliding events.

Honestly, I couldn’t quite get a grasp on how to understand Alfonso Cuarón’s approach until I saw a tweet from Guillermo del Toro the other day. “In every sense, Roma is a fresco, a mural, not a portrait,” he wrote.

And it’s true. The background of each shot matters as much, if not more, than the foreground, and frequently they’re playing off one another in one big, looping narrative. I do wish the film had gotten closer to its main character, but del Toro’s analogy helps me appreciate its grander…

Happy Birthday, Edgar Allan Poe!

See the original posting on Boing Boing

Neil Gaiman says Edgar Allan Poe should be read aloud, and he’s right: he recorded this video of him reading “The Raven” in 2016 as part of Pat Rothfuss’s Worldbuilders charity drive. It’s Poe’s birthday today, and I can think of no better way to celebrate it than to listen to it again.

Other ways to celebrate this magnificent torch:

* The spectacular pop-up edition

* The 50s hipster argot edition

* The 1969 rock-and-roll version

* Vincent Price and Boris Karloff’s Raven-inspired magic duel

Discounted 128GB iPads, and hundreds off of LG OLED 4K TVs are this week’s best deals

See the original posting on The Verge

2019 has delivered some pretty decent deals already, and this weekend’s roundup showcases the wide range of tech that’s available for less. Super Bowl LIII and the Academy Awards ceremony loom, which means that some great deals on home entertainment gear like TVs and soundbars will be coming soon. But until then, let’s take a look at this week’s best deals.

Newegg is offering $40 off of the PS4 Pro with the offer code EMCTUUD67 used at checkout. Any discount on Sony’s 4K-ready console is rare, and given that 2019 will be another big year for the console (The Last of Us Part II, Death Stranding, Judge Eyes, and Ghost of Tsushima are expected to launch this year), it’s worth picking it up if you don’t have one yet.

Full Color Dot Matrix Is The Art We Need

See the original posting on Hackaday

Fans of 80s-era computer printing technology are few and far between, but Apple’s ImageWriter II was a beast of a printer. This tractor feed dot-matrix printer is nigh-indestructible. The print quality was actually pretty great. It was loud as hell, which is a mark of quality electromechanical components. It could do color, and color dot-matrix art on tractor feed paper is the aesthetic we need. If you’re not convinced yet, you can also take off the perforations from tractor feed paper and make a cool little paper snake.

Dolby made a secret app for recording studio quality audio on your phone

See the original posting on The Verge

Dolby has been quietly testing a new mobile app for recording and cleaning up audio under the codename “234,” as first spotted by TechCrunch. The app, which was available through a website sign-up form, lets you record audio (a la Voice Notes), cancels background noise, and then apply presets, with names like “Amped,” “Thump,” and “Bright,” to theoretically make your recordings sound more professional.

The sign-up site, which has since been deactivated, advertised the app by saying: “How can music recorded on a phone sound so good? Dolby 234 automatically cleans up the sound, gives it tone and space, and finds the ideal loudness. It’s like having your own producer in your phone.” Those are big claims. Luckily, I snagged a copy of the app…

Unobtanium Bezels Finally Modeled For 3D Printing

See the original posting on Hackaday

In 1991, Apple released the Quadra line of computers, named after their utilization of the new Motorola 68040 CPU. The Quadra line initially consisted of two models, the Quadra 700 and the Quadra 900. These two models, and the Quadra 950, released as a slight upgrade to the 900, were the peak of performance. You could conceivably load these machines up with 256 Megabytes of RAM, in an era where hard drives hovered around 80 Megabytes. This much RAM would cost as much as a house. These were powerhouses, the first ProTools workstations, and they ran Jurassic Park. If you …read more

Sonos Beam is $50 off in time for the Super Bowl

See the original posting on The Verge

If you want to improve on your television’s built-in speakers, which are likely to be terrible, there are a lot of ways to do it. The Sonos Beam soundbar is one of them, and starting today (until February 3rd), Amazon is reducing its cost to $349 for a savings of $50.

The Beam is Sonos’ most affordable soundbar by a long shot, and it’s made just a bit cheaper by this deal. Its good looks and a few unique features make it worth considering over cheaper soundbars. First, it’s a smart speaker and soundbar rolled up into one that supports Alexa voice commands, and Google Assistant is slowly but surely on its way. Once it’s plugged into your television’s HDMI ARC port (most, but not all, recent TVs have one), Alexa can power your TV on and…

Lime SDR (and Pluto, Too) Sends TV

See the original posting on Hackaday

If you have experienced software defined radio (SDR) using the ubiquitous RTL SDR dongles, you are missing out on half of it. While those SDRs are inexpensive, they only receive. The next step is to transmit. [Corrosive] shows how he uses DATV Express along with a Lime SDR or a Pluto (the evaluation device from Analog Devices) to transmit video. He shows how to set it all up in the context of ham radio. An earlier video shows how to receive the signal using an SDR and some Windows software. The receiver will work with an RTL SDR or a …read more
