Digital Attenuator Goes from Manual to Arduino Control

See the original posting on Hackaday

[Kerry Wong] comes across the coolest hardware, and always manages to do something interesting with it. His widget du jour is an old demo board for a digital RF attenuator chip, which can pad a signal in discrete steps according to the settings of some DIP switches. [Kerry]’s goal: forget the finger switch-flipping and bring the attenuator under Arduino control.

As usual with his videos, [Kerry] gives us a great rundown on the theory behind the hardware he’s working with. The chip in question is an interesting beast, an HMC624LP4E from Hittite, a company that was rolled into Analog Devices …read more

Star Trek: Discovery’s Season 2 Trailer Teases Spock, Christopher Pike, and Tig Notaro

See the original posting on Slashdot

CBS has released a “Season Two Premiere” for Star Trek Discovery, offering the first look at the upcoming season of the show on CBS All Access. The first season launched late last year and finished up in February after a brief hiatus. The Verge reports of what to expect from the upcoming season, which is expected to premiere sometime in early 2019: [It] appears to begin with Captain Christopher Pike (Anson Mount) coming aboard and taking control of the USS Discovery after a series of mysterious “red bursts” are detected, simultaneously spread out across 30,000 light years. Burnham later claims “Spock is linked to these signals.” New series guest star Tig Notaro makes a very Tig Notaro joke, Pike encourages the crew to “have a little fun,” Tilly yells about “the power of math” — a good time, in other words. (After all, the whole thing is set the tune of Lenny Kravitz’s “Fly Away,” so you know it’s real.) Bonus: at the end we meet another, very sniffly alien Discovery crew member, proving Saru and the bridge androids aren’t the sole non-humans aboard the ship, as we once feared. At the Discovery panel at San Diego Comic Con’s Hall H, a new Star Trek series was announced, called Star Trek: Short Treks. It is “a series of monthly short-form stories that will function like bonus content and air on CBS All Access in conjunction with the larger Star Trek: Discovery series,” reports The Verge. “CBS says Short Treks, which will air in installments of about 10 to 15 minutes, is ‘an opportunity for deeper storytelling and exploration of key characters and themes that fit into… the expanding Star Trek universe.'”

Open Source Laboratory Rocker is Super Smooth

See the original posting on Hackaday

Lab equipment is often expensive, but budgets can be tight and not always up to getting small labs or researchers what they need. That’s why [akshay_d21] designed an Open Source Lab Rocker with a modular tray that uses commonly available hardware and 3D printed parts. The device generates precisely controlled, smooth motion to perform automated mild to moderately aggressive mixing of samples by tilting the attached tray in a see-saw motion. It can accommodate either a beaker or test tubes, but since the tray is modular, different trays can be designed to fit specific needs.

Source code and schematics are …read more

Hello Vue: A Quick Tutorial on Getting Started With Vue

See the original posting on DZone Python

A quick tutorial on getting started with Vue, including the use of a component from Kendo UI for Vue. Designed to be a great starting point with an example that, like Vue itself, is scalable.

This tutorial is aimed at the first-time Vue explorer. I’ll show you how to create a simple example using Vue, and then I’ll add in some interactivity and a UI component, and finally add in more functionality and a Kendo UI component. While this tutorial demo is quite basic, it outlines all the key elements of adding in features and functionality using Vue. It would be very easy to expand on the demo code and swap in more complex components. My example, like Vue itself, is scalable.

Freeform has renewed Marvel’s Cloak & Dagger for a second season

See the original posting on The Verge

Marvel has largely taken a backseat this year at San Diego Comic-Con: Marvel Studios skipped the con, but there’s been a bit of news from its television divisions: it announced that the second season of Iron Fist will begin later this fall, and today, it revealed that its Freeform show, Cloak & Dagger will come back for another season next year.

The show follows two teenagers, Tandy Bowen (Olivia Holt) and Tyrone “Ty” Johnson (Aubrey Joseph), who gained superpowers from an accident. The show has proven to be extremely relevant, tackling issues such as racism, depression and drug abuse.

According to The Hollywood Reporter, Freeform has renewed the show for a second, 10-episode season, which will begin streaming in the spring of 2019….

Bananas Against Racism

See the original posting on Hackaday

This is a tale as old as time. Not love, it is about keeping something you made safe from those who would destroy something beautiful. In this case, the thing of beauty is a talking banana who reads Twitch and Youtube comments. The ne’er-do-wells are trolls seeking to ban-anana the account by forcing it to recite restricted words.

The problems stem from a visit from [Greekgodx], whose followers tend toward the dark side. When they set their sights on [Mike Nichols]’ yellow automaton, things slipped into a bleak place, and a twenty-four-hour ban falls on the fruit. A bunch of …read more

Joss Whedon is developing a ‘richly diverse’ Buffy the Vampire Slayer reboot

See the original posting on The Verge

Joss Whedon’s TV series Buffy the Vampire Slayer ended its original run back in 2003, but 15 years later, a new iteration of the show is in development. Deadline reports that Whedon and Midnight, Texas creator Monica Owusu-Breen are developing the series at Fox 21 TV Studios. There is no home yet for the new Buffy, but the plan is for the series to be pitched to cable networks and streaming services later this summer.

The original show followed Buffy Summers (Sarah Michelle Gellar), a “Slayer” destined to fight evil forces in her new hometown of Sunnydale. Inspired by Whedon’s feature film of the same name, the series ran for seven seasons, inspiring a spin-off series (Angel), a larger expanded universe of comics and novels, and a…

The next Star Wars novels will flesh out the prequel era

See the original posting on The Verge

Today at San Diego Comic-Con, Lucasfilm assembled a panel of its authors to preview the next crop of Star Wars books and comics. With Episode IX yet to begin production, the next couple of novels will focus on the prequel era.

Ever since Timothy Zahn wrote Heir to the Empire in 1991, books have been a major part of the larger Star Wars franchise, expanding the story beyond the films and introducing new characters. When Disney acquired Lucasfilm in 2012, the past books and comics — the Star Wars Expanded Universe — were rendered non-canon. But ever since, publisher Del Rey has worked with the Star Wars Story Group to coordinate all the franchise’s new stories across its various media to ensure that everything fits together and…

Watch the first trailer for M. Night Shyamalan’s Glass

See the original posting on The Verge

A year ago, M. Night Shyamalan scored a surprise hit with his film Split, about a teenager named Casey (Anya Taylor-Joy) being kidnapped and held hostage by Kevin Wendell Crumb (James McAvoy), a man suffering from dissociative identity disorder. The end of the film had a surprise: a direct tie-in to Shyamalan’s comic-book superhero homage Unbreakable, which led to an announcement that his followup film Glass would further connect the two films. At its Hall H presentation at San Diego Comic-Con today, Universal Pictures released a full trailer for the film.

The trailer introduces Dr. Ellie Staple (played by Sarah Paulson), a psychiatrist who specializes in “those individuals who believe they are superheroes,” addressing Bruce Willis’ U…

Failed 3D Print Saved with Manual Coding

See the original posting on Hackaday

Toast falls face down. Your car always breaks after the warranty period. A 3D print only fails after it is has been printing for 12 hours. Those things might not always be true, but they are true often enough. Another pessimistic adage is “no good deed goes unpunished.” [Shippey123] did a good deed. He agreed to make a 3D printed mask for his friend to give as a gift. It was his first print he attempted for someone else after about four months’ experience printing at all. After 20 hours of printing, he noticed the head was moving around in …read more

Star Trek: Discovery’s season 2 trailer teases Spock, Christopher Pike, and Tig Notaro

See the original posting on The Verge

CBS held a big panel Friday for the latest installment of the Star Trek franchise, Star Trek Discovery, offering the first look at the upcoming season of the show on CBS All Access.

Star Trek Discovery launched last year on the channel’s much-maligned digital platform, and was a new look for the Trek franchise: it broke a number of the series’ traditional conventions, and ended up being a much darker show than previous series installments, a move that has divided the fandom. The show, set about a decade before the original 1966 Star Trek aboard the eponymous USS Discovery, follows the disgraced Starfleet officer Michael Burnham after she’s found guilty of mutiny, stripped of her rank, and sent to space jail. When her services are…

Star Trek is getting a series of standalone mini ‘Short Treks’ episodes

See the original posting on The Verge

When Star Trek: Discovery’s original showrunner, Bryan Fuller, first met with CBS executives about bringing a new Star Trek series to the small screen, he proposed the new property as an anthology series, similar to the format and style of Ryan Murphy’s American Horror Story. That would allow a much wider lens on the larger Trek universe than any of the previous series or films had been able to accomplish. CBS was reportedly interested, but suggested he start with a serialized story first to test the waters.

With his exit from the show in October 2016 went any chance of a more eclectic take on Discovery — until now. This afternoon at the Discovery panel at San Diego Comic-Con’s Hall H, co-creator and current showrunner Alex Kurtzman…

The Walking Dead gets a season 9 trailer and October 7th release date

See the original posting on The Verge

The Walking Dead is preparing for a life after Rick Grimes, as both actor Andrew Lincoln and comic creator Robert Kirkman confirmed this week at San Diego Comic-Con that the show’s season 9 will be Lincoln’s last. Now, at The Walking Dead’s official Comic-Con panel today, AMC has released the first trailer for season 9 and confirmed an October 7th, 2018 premiere date.

Season 9 takes place after the “All Out War” saga of Kirkman’s comic, and it will be the first season in more than four years that showrunner Scott Gimple will not be in charge. Long-time writer and story editor Angela Kang will be taking over as Gimple assumes the chief content officer role of the expanding franchise, which includes Fear the Walking Dead and a number of…

Creating a Custom Element Decorator Using TypeScript

See the original posting on DZone Python

It’s a known fact that I’m betting on Web Components. The last time that I delivered a session about Web Components, someone in the audience asked me how he can remove some of the boilerplate he needs to write in order to create a custom element. I answered that you can probably use a compiler such as Stencil or a library such as Polymer or even write your own TypeScript decorator to do that.

So… a few days ago I had some spare time to sit and play with both Custom Elements and TypeScript decorators. As a result, I wrote a small code snippet that can help you to get started and build your own custom element decorator.

Arduino Powered Arcade Button Lighting Effects

As if you already weren’t agonizing over whether or not you should build your own arcade cabinet, add this one to the list of compelling reasons why you should dedicate an unreasonable amount of physical space to playing games you’ve probably already got emulated on your phone. [Rodrigo] writes in to show off his project to add some flair to the lighted buttons on his arcade controller. (Google Translate)

The wiring for this project is about as easy as you’d expect: the buttons connect to the digital inputs on the Arduino, and the LEDs on the digital outputs. When the …read more

Cargo is teaming up with Uber to satiate your mid-trip munchies

See the original posting on The Verge

Cargo, the company that sought to make ride-share vehicles a bit more like drive-by convenience stores replete with snacks and tech accessories for sale, has announced that it’s officially joining forces with Uber.

Cargo, which first launched in 2017, gives ride-share drivers boxes filled with free samples and purchasable snacks, along with tech gear like spare phone chargers and headphones. Drivers are promised that they can keep 25 percent of the sales, and $1 per item — even if the rider is just grabbing a free sample.

Right now, riders pay for these items through Cargo’s app, but Uber might bake these features…
