A big part of the Hackaday Prize this year is robotics modules, and already we’ve seen a lot of projects adding intelligence to motors. Whether that’s current sensing, RPM feedback, PID control, or adding an encoder, motors are getting smart. Usually, though, we’re talking about fancy brushless motors or steppers. The humble DC brushed motor is again left out in the cold.
This project is aiming to fix that. It’s a smart motor driver for dumb DC brushed motors. You know, the motors you can buy for pennies. The motors that are the cheapest way to add movement to any …read more
Whether it’s through changes in the map itself or the introduction of new weapons like the Stink Bomb and the Thermal-Scoped AR, Fortnite Battle Royale continues to evolve with each passing week. So it’s no surprise that more changes are afoot for the world’s biggest video game. First and foremost, a new Playground mode will […]
Daguerreotypes – photos made with a process that used mercury vapors on an iodine-sensitized silvered plate – break down quite easily. The result is a fogged plate that that, more often that not, is completely ruined by time and mistreatment. However researchers at Western University have created a system that uses synchrotrons and “rapid-scanning micro-X-ray […]
Oakland firefighter Kevin Moore, who is black, was doing vegetation-management inspections, in full uniform, with a radio and identification, when residents became suspicious and called police. According to a supervisor, the fire department sends out pamphlets before the inspections, hosts community meetings, and does everything else they can to spread the word. If nobody is home, the law permits firefighters to conduct an outdoor inspection anyway. One day last month, a resident called the police about Moore and another sent the cops video of Moore ringing a doorbell to do an inspection. Then last week, it happened again. From the San Francisco Chronicle:
As Moore was finishing up, he said he turned around to find the resident outside near the front steps of the house, video-recording him on a cell phone.
He kind of startled me, Moore said. He says, Well, what are you doing here? I say, Were here doing our annual vegetation inspection. Then he asks for ID. I say no problem. He takes a picture of my ID and says I need to get a different one. Ive had that ID for years. Its kind of dark, and Im more of a dark-skinned black guy, but you can still see me.
Moore said he suggested that if the resident were still concerned, he could simply look out onto the street where a big red fire engine is right there.
On Sunday, TV Globo and SportTV journalist Julia Guimarães was reporting on camera from the World Cup in Yekaterinburg, Russia when a random asshole tried to kiss her. If only she could have punctuated her response with a swift kick to the nuts.
With more and more embedded systems being connected, sending state information from one machine to another has become more common. However, sending large packets of data around on the network can be bad both for bandwidth consumption and for power usage. Sure, if you are talking between two PCs connected with a gigabit LAN and powered from the wall, just shoot that 100 Kbyte packet across the network 10 times a second. But if you want to be more efficient, you may find this trick useful.
As a thought experiment, I’m going to posit a system that has a database …read more
Oculus is officially launching Oculus TV, its dedicated hub for watching flatscreen video in virtual reality, on the standalone Oculus Go headset. Oculus TV was announced at last months F8 conference, and it ties together a lot of existing VR video options, highlighting Oculus attempts to emphasize non-gaming uses of VR. The free app features a virtual home theater with what Oculus claims is the equivalent of a 180-inch TV screen. It offers access to several streaming video services, including subscription-based platforms like Showtime and free web television services like Pluto TV as well as video from Oculus parent company Facebook.
You can already watch a lot of non-VR video on Oculus Go; Showtime, Netflix, and Hulu have standalone…
Industrial manufacturing company Cemtrex has taken the idea of an all-in-one workstation to an entirely new level. Its sit / stand SmartDesk has everything from three monitors to a scanner built into a minimal setup that it says combines and reimagines all the needs of a modern office.
The desk has three 24-inch IPS touchscreen displays, which, combined, is a total of 72 inches. The company says that it uses a proprietary touch gesture system, so you can flip through images and documents with a wave of your hand. (Good luck if you spill something or break it.) Theyre all connected to a Windows PC thats powered by an eighth-generation Intel Core i7 and attached to the underside of the desk. Theres one USB 3.1 Type-C port, two USB 3.1…
Oculus is launching a TV app for users to check out streaming video content on a big virtual screen on the Oculus Go headset. The company highlighted Oculus TV at Facebook’s F8 developer conference as one of four new Oculus-built apps that would allow users to get the most out of the inexpensive headset. The […]
Only a few years ago, Google Earth was the only practical way to see all of Google’s satellite and 3D imagery. These days, Google Maps pretty much offers all of the mapping features that casual users need, but Google continues to quietly develop Earth and today, the company announced it is adding an area measurement tool […]
Getting mental health services can be burdensome. And if you’re already going through a tough time, you’re probably looking for help sooner than later. But based on the current landscape, it can take months to find the right therapist who also takes your insurance. This is where Meru Health hopes to come in. By providing […]
Illustrator Versiris has a new series called Video Games Retold, and the first episode is a worthy entry for the story of Dark Souls. It’s wonderful if you just want to revisit the game’s themes, or even if you never played and want to know the story line. (more…)
This is the Dual-rotor embedded multilink Robot with the Ability of multi-deGree-of-freedom aerial transformatiON, aka DRAGON. Designed at the University of Tokyo, this modular bot can rearrange its shape, from an agile snake to a spiral to a flying “L” shape. From IEEE Spectrum:
Whats exciting, though, is why this robot was designed to transform in the first place. The video, whichspoiler alertis actually a teaser for a 2018 IROS paper, shows the robot changing its shape in order to squeeze through a small gap, and we were told at ICRA that DRAGON is able to autonomously decide how to transform when given the constraints of the space it needs to pass through. Theres more potential here than just fitting through small spaces, though: The researchers conceptualize this robot as a sort of overactuated flying arm that can both form new shapes and use those shapes to interact with the world around it by manipulating objects. Eventually, DRAGON will wiggle through the air with as many as 12 interlinked modules, and itll use its two ends to pick up objects like a two-fingered gripper. And we can imagine DRAGON wrapping itself around stuff to move it, or using direct contact with the environment to do other exciting things.

Han Solo’s blaster used in “Star Wars: Episode VI Return of the Jedi” sold for $550,000 at a Las Vegas auction on Saturday. Turns out that Ripley’s Believe It Or Not bought it. Believe it… or not. The prop was part of a collection sold off by the movie’s art director James L. Schoppe. From Rolling Stone:
Other items at Saturday’s auction included an original “Biker Scout Blaster” (sold for $90,000) and an Ewok prop axe ($11,000) from Return of the Jedi.
However, Han Solo’s blaster fell well short of the record for the priciest Star Wars item in the franchise’s auction history: In June 2017, an R2-D2 unit that was seen in numerous Star Wars films sold at auction for $2.76 million, over its $2 million pre-auction estimate.
This time around, were requesting the homepage for Google.com and, at the same time, sorting a randomly generated array of 1 million numbers. This is going to take a few seconds, so its perfect for us to show how well this behaves. Were also going to measure the time it takes for the worker thread to perform the sorting and were going to send that value (along with the first sorted value) to the main thread, where well display the results.A few days ago, version 10.5.0 of Node.js was released and one of the main features it contained was the addition of initial (and experimental) thread support.
This is interesting, especially coming from a language thats always prided itself on not needing threads thanks to its fantastic async I/O. So why would we need threads in Node?
The Pax Era, a design-heavy, rectangular cannabis vape thats positioned as an alternative to the standard pen-battery-and-cartridge setup, didnt sell me when it came out in January. It has proprietary cartridges with a selection of extracts from a curated group of vendors. That seems to counter the versatility that made the flagship Pax product (which can be used with any dry herb or concentrate) so appealing.
An app and firmware update was released last week, however, so that hand-holding pays off. A new feature called session control helps the user control dosage in a more precise way.
Instead of just choosing the temperature, users can pick from a selection of…
Electric scooter sharing services are exploding on the west coast, but after users drop them wherever, they eventually need to be recharged. This fella got a little too ambitious for the cops in “catching” wayward scooters for recharging. (more…)
According to the Daily Beast, Right-wing goofball Glenn Beck’s media company is in serious financial trouble, but he doesn’t want to talk about it. This video begins with CNN’s Brian Stelter interviewing Beck about his support for Trump, and Beck is happy to scold Stetler by spouting hypocrisy and false equivalencies, but as soon as the subject of Beck’s ailing company is brought up, he has nothing to say.
