Toy R/C Car Upgrade to Hobby Grade Parts

See the original posting on Hackaday

[HobbyPartz] wanted his toy grade Radio Controlled (R/C) to drive a bit more like the real thing, so he upgraded it to hobby grade electronics.

If you didn’t know, there’s a pecking order in the R/C world. There are the toy grade cars which you can find at your local big box store, and the hobby grade cars, which grace the shelves of the local hobby shop. Toy cars often come with great looking shells – Corvettes, Lamborghinis, Porsches,  or even Ferraris. It often seems like the manufacturer spent all their money licensing and molding the shell though because the …read more

What Are @HostBinding() and @HostListener() in Angular?

See the original posting on DZone Python

To understand @HostListener and @HostBinding, you should have basic knowledge about directives in Angular. There are three types of directives in Angular:

  1. Component
  2. Attribute Directive
  3. Structural Directive

The basic difference between a component and a directive is that a component has a template, whereas an attribute or structural directive does not have a template. To understand these two concepts, let us start by creating a simple custom attribute directive. The directive below changes the background color of the host element:

An IoT Christmas Tree For Your Hacker-Mas Celebrations

See the original posting on Hackaday

Smart Christmas trees may soon come to mean something more than a fashionably decorated tree. Forging ahead with this new definition, [Ayan Pahwa], with help from [Akshay Kumar], [Anshul Katta], and [Abhishek Maurya] turned their office’s Christmas Tree into an IoT device you can watch live!

As an IoT device, the tree relies on the ever-popular ESP8266 NodeMCU — activated and controlled by Alexa, as well as from a web page. The LEDs for the tree — and the offline-only tree-topper controlled by an Arduino Pro Mini — are the similarly popular Neopixels.

For those viewing online, a Raspberry Pi …read more

Have Your Own 200 Water Street Digital Clock

See the original posting on Hackaday

On the front of a building in New York City, above a branch of the ubiquitous Starbucks coffee chain, there is a clock. It is no ordinary clock, the 200 Water Street clock is an art installation created by the artist [Rudolph de Harak], and consists of 72 lighted numbers which are illuminated in sequence to show hours, minutes, and seconds. It is a landmark of sufficient fame that [Jason Ben Nathan] and [Eldar Slobodyan], Cornell University students of [Bruce Land], decided to make their own tribute to it as their course project.

It’s a fairly straightforward build, thanks to …read more

Watch: video of a stable plasma torus

See the original posting on Boing Boing

https://youtu.be/Ht0_Kkx5-YU

Caltech posted video of a stable plasma torus, created by engineers using water and a dielectric plate: “lightning in a bottle, but without the bottle.

In addition, engineers working with the plasma noticed that their cell phones encountered high levels of radio frequency noise—static—while they were in the same room as the experiment. It turns out that the plasma ring emits distinct radio frequencies. “That’s never been seen before. We think it’s because of the piezo properties of the materials that we used in our experiments,” Pereira says, referring to the materials’ ability to be electrically polarized through mechanical stress—in this case, the flowing of water.

They’ve got no idea what it might be useful for, but have already filed a patent on the method for genereating the torus. Commercial proposal: a pretty random number generator to replace the lava lamps in Cloudflare’s HQ.

The movies that transported and troubled us in 2017

See the original posting on The Verge

Throughout the final week of 2017, culture writers from across Vox Media will be chatting about the best works of the year. In this installment, Vox’s Todd VanDerWerff, Alissa Wilkinson, and Genevieve Koski; The Verge’s Tasha Robinson; and Polygon’s Julia Alexander talk about the movies of 2017.

Todd VanDerWerff: My favorite movies in 2017 weren’t escapism, not precisely, but they did take me so thoroughly out of my own point of view that reentering reality afterward could feel a little like resurfacing after a deep-sea dive. From the intimate details of Lady Bird to the bleakly comedic terror of Get Out, from the cat’s-eye-view shots of Kedi to the sudden plunge into the vastness of infinity in A Ghost Story, movies often felt like a…

A look back at the state of racial representation in Hollywood this year

See the original posting on The Verge

2017 was a good time for racial representation in movies. From films like Hidden Figures to Coco, it seems that Hollywood is more invested than ever in telling stories with diverse leads. Not all of the news is good, however; the past year also saw two more whitewashing controversies thanks to the live-action Ghost in the Shell and Netflix’s Death Note, and people of color on the big screen still lag far behind their populations in real life. Although it’s difficult to square all these trends into one easily understood narrative, especially as no single report out there has all the numbers and data, we can still piece together a general idea of how this year stacked up against years prior.

Get Out, which premiered in February, explored…

HQ Trivia is now available in beta from the Play Store

See the original posting on The Verge

Earlier this month, HQ Trivia announced that the app would finally be available for Android users, allowing them to pre-register to download it. The app is now available in the Google Play Store’s Early Access section.

The game launched this past fall on iOS. The Android app is still in beta, and the product page notes that the app is potentially unstable. Recode reported earlier this month that the company is working to raise money from venture capitalists for a potential $100 million valuation. The addition of an Android app will likely help boost its user base.

Created by Vine co-founders Rus Yusupov and fellow co-founder Colin Kroll, the game is a live trivia contest that has become extremely popular in recent months. Players…

Voice interfaces beginning to find their way into business

See the original posting on TechCrunch

 Imagine attending a business meeting with an Amazon Echo (or any voice-driven device) sitting on the conference table. A question arises about the month’s sales numbers in the Southeast region. Instead of opening a laptop, opening a program like Excel and finding the numbers, you simply ask the device and get the answer instantly. That kind of scenario is increasingly becoming a… Read More

The Verge Playlist: New Year’s Eve

See the original posting on The Verge

What’s the worst that could happen tonight, the most loaded night of the year? You could have no one to kiss or no one to get drunk with, or worse — you could have both and still not have a good time. It’s so much pressure and even the nicest things you can think of will likely involve so much “walking outside” and “being in a crowd” and “money,” that it couldn’t possibly be worth it. A new year? I’ve seen 940 of them already. An alternate plan that I believe is very good is to sit at home and watch a warm, non-challenging movie about love and friendship and wearing turtlenecks under blazers. For example: the best New Year’s Eve movie of all time, Nora Ephron’s When Harry Met Sally, which features an unhelpful explanation of the song…

The Verge 2017 tech report card: Apps

See the original posting on The Verge

The biggest story about apps in 2017 was, well, stories. Snapchat still deserves the credit for coming up with the concept, and Instagram shamelessly ripped it off back in 2016, but this year, everyone got on board. WhatsApp added stories (and then later made them less prominent after users complained). Facebook added stories (and tried to guilt users into using them with digital ghosts of friends.) Medium — a largely text based app — added stories! YouTube added stories! It’s stories all the way down as far as the eye can see.

Of course, there’s a very good reason for all this — stories are popular, and popular places on the internet are ripe for that sweet advertising money.

Aside from stories, though, the past year saw Instagram’s…

The newest DJ at this Prague nightclub is a KUKA arm robot

See the original posting on The Verge

A club in Prague named Karlovy Lazne has recently introduced a robot DJ that alternates with a human to program music for the dance floor throughout the night, as reported by Reuters. Now in rotation for a few weeks, the robot has software that allows it to choose songs, select CDs from a rack, insert them into CDJs, and then play the songs. It also has some pretty sweet dance moves.

The club employed a robotics firm to have the robot specifically made for DJing. It’s an adaptation of a KUKA arm primarily used in the automotive industry. Rigged with software that helps it choose songs, the robot’s pincers grab CDs, and then show off some moves before placing them in one of the two CDJs in front of it. It’s unclear from the article if the…

A new featurette for Netflix’s Bright reveals the backstory that should have been in the film

See the original posting on The Verge

Netflix recently began streaming its big blockbuster Bright, and it hasn’t been entirely well received by critics. The action film is set in a modern fantasy world where elves, humans, and orcs live alongside one another, but it only alluded to the larger world that drives much of the story. To help fill in those gaps, Netflix released a short video that highlights all of the history of the world that would have made the story a bit more comprehensible.

Bright might not have been great film, but it did introduce viewers to an intriguing fantasy world; it just didn’t explain any of it. The movie follows a human police officer and his orc partner after they discover a magic wand, and fight to escape with their lives from various criminal…

Twitter ended the year on a fascinating run

See the original posting on TechCrunch

 It’s been pretty easy to point at Twitter and, with each quarterly moment when it discloses its financial guts, let out a long exasperated sigh. But then something interesting happened in the back half of 2017: it went on a rather spectacular run, and though ending on a bit of a slump, it looks like it could finish the year up more than 25 percent — which, by Twitter terms, is… Read More

Old Logic Analyzer becomes New PC Case

See the original posting on Hackaday

There are a lot of cool ways to wrap a case around your custom PC build. But the off-the-shelf stuff doesn’t really set your machine apart from the herd, no matter how many RGB LEDs you put inside. If you really want to stand out, think out of the box, and build your PC into the case of an old logic analyzer.

Looking for a little retro cool factor, [Bob Alexander] turned to the world’s boneyard, eBay, and rounded up a dead H-P 1653 logic analyzer. State of the art in 1989 but not worth repairing by [Bob]’s lights, so …read more

The Verge 2017 tech report card: Headphones

See the original posting on The Verge

My best way to look back on 2017 in the world of headphones is to consider the things I wasn’t able to say a year ago.

The best portable headphones today are wireless. That wasn’t true last year — at least not in my Beoplay H6-loving judgment — however Bowers & Wilkins’ PX have shot to the top of the charts with an exquisitely tuned sound, handsome looks, and solid battery life. The noise-cancelling PX are a transformational pair of headphones because they take NC cans out of their traditional role of being merely functional and into the competition for best sound quality. Gone are the days of Bose singularly dominating the NC field with awesome ergonomics but mediocre sound: today we have all the big names like Beats, Sony, and…
