Bitmain forced to shut down Israel operations due to cryptocurrency bear market


It appears the downturn of the cryptocurrency market is having a ripple effect (pun intended) on the industry. Numerous blockchain businesses have been forced to close down or lay off staff to survive – and the latest one is Bitmain. The mining giant is the latest to be hit by the cryptocurrency bear market and is shutting down its Israel-based development center, Bitmaintech Israel, Globes Israel reports. The development center was set up two years ago, and will close this week laying off its 23-people-strong staff in the process. Gadi Glikberg, head of Bitmaintech Israel and VP at Bitmain, will…

‘Loot boxes’ in video games could be giving kids a gambling problem


The number of children with gambling problems has “quadrupled to more than 50,000 in just two years”, according to recent reports. The alarming figures come from the UK Gambling Commission’s latest annual statistics, which showed that the prevalence of problem gambling among children had risen to 1.7 percent, compared with 0.4 percent in 2016, and 0.9 percent in 2017. To put these figures into context, problem gambling among teenagers overall has actually been declining in the UK over the past 20 years. A review of research revealed that in 2000, roughly 5 percent of teenagers met the criteria for problem gambling – by…

Microsoft Teams is growing ridiculously fast


A report from Spiceworks shows that adoption of Microsoft Teams – the Slack rival from Redmond – is growing rapidly and is set to become the second-biggest workplace chat app by 2020, surpassing both Slack and Google Hangouts. The findings come from a survey of 900 IT companies distributed across the US and Europe. Spiceworks found that the penetration of Microsoft Teams grew from 3 percent in 2016 to 21 percent in 2018. This growth can be attributed partially to the fact that Microsoft made Teams available globally in 2017. Previously, it was only available to business users of Office…

PlayStation Classic Hacked Live on Stream

When Sony announced they planned to release their own classic/mini/plug-n-play system this year, many fans were filled with excitement at the chance to relive countless classic games from the 90s. However, once the actual list of titles were made public that excitement faded as reality set in. So many favorites like Crash Bandicoot and Spyro the Dragon were left off the final PlayStation Classic list, no doubt due to the complexity of licensing agreements. That will all soon change now that [YifanLu] cracked the PlayStation Classic live on a Twitch stream thus laying the ground work for swapping-in a “more curated” list of classic PlayStation games.

Over the course of three days, [YifanLu] documented the process in real-time of cracking the PlayStation Classic’s security armed with little more than a keyboard. The crux of the hack came from fellow hacker [madmonkey]’s revelation that the firmware update files were signed with a key that had been mistakenly left behind on the device by Sony. Or as [YifanLu] stated, “One key is, ‘Hey am I Sony?’…The other key is saying, ‘Hey I am Sony.’ They distributed the key that identifies [themselves] uniquely and this key doesn’t expire for another 50 years or so.”

Once inside [YifanLu] was able to sideload a prototype image of a Crash Bandicoot over USB. He simply overwrote the first title on the list, Battle Arena Toshinden, and could launch the freshly injected game from the PlayStation Classic menu screen. The video below is from Day 3 of the PlayStation Classic hacking series, so skip to timecode (03:44:45) to see the results in action. For a bit more nuance there are another 15 hours or so of video to catch-up on [YifanLu]’s Twitch page. Here’s to everyone getting their favorite onto the PlayStation Classic in the near future.

PUBG Mobile’s Global Finals proved that mobile esports are serious business


When you get invited to fly to Dubai to watch a bunch of people play a game on their phone, you don’t say no. Especially when the people are professional gamers, the prize is $600,000, and the game is PlayerUnknown’s Battlegrounds. The idea of a heated esports tournament taking place in the world’s most poshest playground intrigued me, so I packed a suitcase with ‘modest clothes’ (as the invite specifically instructed) and hopped on a plane.

South Korean bank wants to use blockchain to reduce human error


South Korea’s second largest bank is in the middle of rolling out a blockchain-based system designed to reduce human error. Shinhan Bank is using the blockchain for Interest Rate Swap (IRS) transactions. The bank purportedly implemented this system at the end of November, local news reports. Interest Rate Swaps can get quite complicated, but fundamentally they are a type of futures contract based on swapping an interest rate between a number of parties. Two or more parties can enter into a swap contract and agree to pay each other based on the increase (or decrease) of interest rates. It allows…

Hydrogen Powered Nerf Blaster Is Dangerously Awesome

Nerf blasters have been around for decades now, exciting children and concerning parents alike. Most are powered by springs or compressed air, and are the ideal holiday toy for putting delicate family heirlooms at risk. Not content to settle for the usual foam-flinging sidearm, [Peter Sripol] decided to take things up a notch.

The build starts with a MEGA CYCLONESHOCK blaster, which uses the larger red NERF darts as ammunition. Water tanks are rigged to the outside, fitted with stainless steel electrodes. The original spring & plunger firing  assembly is then removed, to make room for a firing chamber made out of copper pipe. A small taser-like device is used as an igniter. When the charging switch is pressed, current is passed through the electrodes in the water, which splits the water into hydrogen and oxygen gas. This is then passed to the firing chamber, where it can be ignited by the taser module, activated by the trigger.

Despite some issues with the blaster occasionally destroying darts due to what appears to be overpressure, it is capable of higher shot velocities than the stock blaster. For all its complexity, performance is somewhat hit and miss, but the cool factor of a handheld hydrogen bubbler is hard to ignore. [Peter] does note however that the combination of explosive gases and dangerous catalyst chemicals make this one build that’s probably best left to adults.

If this NERF hack isn’t dangerous enough, you might prefer these Taser darts instead. Video after the break.

Honor’s new View20 gets a 48MP rear camera and an under-screen selfie camera


Huawei’s Honor just fired a massive volley in the smartphone megapixel war. At an event in Hong Kong, the company announced its latest model — the Honor View20. This phone comes with a 48-megapixel rear-facing camera, and a selfie camera that’s embedded within the screen. Powering the rear-facing camera is Sony’s IMX586 sensor, which is coupled with the AI and image processing features of Huawei’s HiSilicon Kirin 980 chipset. This is the same SoC that’s found its way into phones like the Huawei Mate 20 Pro and the Honor Magic 2, and is certainly no slouch. The View20 has a…

From SPIDriver to I2CDriver

Communicating with microcontrollers and other embedded systems requires a communications standard. SPI is a great one, and is commonly used, but it’s not the only one available. There’s also I2C which has some advantages and disadvantages compared to SPI. The problem with both standards, however, is that modern computers don’t come with either built-in. To solve that problem and allow easier access to debugging in SPI, [James Bowman] built the SPIDriver a few months ago, and is now back by popular demand with a similar device for I2C, the I2CDriver.

Much like the SPIDriver, the I2C driver is a debugging tool that can be used at your computer with a USB interface. Working with I2C is often a hassle, with many things going on all at once that need to sync up just right in order to work at all, and this device allows the user to set up I2C devices in a fraction of the time. To start, it has a screen built in that shows information about the current device, like the signal lines and a graphical decoding of the current traffic. It also shows an address space map, and has programmable pullup resistors built in, and can send data about the I2C traffic back to its host PC for analysis.

The I2CDriver is also completely open source, from the hardware to the software, meaning you could build one from scratch if you have the will and the parts, or make changes to the code on your own to suit your specific needs. If you’re stuck using SPI still, though, you can still find the original SPIDriver tool to help you with your debugging needs with that protocol as well.

Christmas POV Display Makes Viewer do the Work

Hackaday readers have certainly seen more than a few persistence of vision (POV) displays at this point, which usually take the form of a spinning LED array which needs to run up to a certain speed before the message becomes visible. The idea is that the LEDs rapidly blink out a part of the overall image, and when they get spinning fast enough your brain stitches the image together into something legible. It’s a fairly simple effect to pull off, but can look pretty neat if well executed.

But [Andy Doswell] has recently taken an interesting alternate approach to this common technique. Rather than an array of LEDs that spin or rock back and forth in front of the viewer, his version of the display doesn’t move at all. Instead it has the viewer do the work, truly making it the “Chad” of POV displays. As the viewer moves in front of the array, either on foot or in a vehicle, they’ll receive the appropriate Yuletide greeting.

In a blog post, [Andy] gives some high level details on the build. Made up of an Arduino, eight LEDs, and the appropriate current limiting resistors on a scrap piece of perfboard; the display is stuck on his window frame so anyone passing by the house can see it.

On the software side, the code is really an exercise in minimalism. The majority of the file is the static values for the LED states stored in an array, and the code simply loops through the array using PORTD to set the states of all eight digital pins at once. The simplicity of the code is another advantage of having the meatbag human viewer figure out the appropriate movement speed on their own.

This isn’t the only POV display we’ve seen with an interesting “hook” recently, proving there’s still room for innovation with the technology. A POV display that fits into a pen is certainly a solid piece of engineering, and there’s little debate the Dr Strange-style spellcaster is one of the coolest things anyone has ever seen. And don’t forget Dog-POV which estimates speed of travel by persisting different images.

[Thanks to Ian for the tip.]

Hackaday Links: December 9, 2018

SpaceX launched a rocket this week, and things did not go as planned. The hydraulics on the grid fins were stuck when the first stage started its atmospheric recovery, and the booster became a fish. The booster landed about a mile or so offshore, which meant we got some great footage of a failed landing, and there are even better shots of the guts of a landed booster. [Scott Manley] whipped out a video showing the ‘new’ discoveries of what’s going on inside a Falcon 9 booster. Interestingly: the weight of the upper stage is carried through the thrust plate of its engine (which makes sense…). There’s a lot of pneumatic stuff going on, and while the composite interstage is very strong along the long axis of the rocket, it doesn’t like being slammed into the ocean.

Winter is coming, and that means you should take your car out during the first snow, drive out to an empty parking lot, and do donuts. I am not kidding this is how you learn to drive in the snow. How do they do it in Russia? They weld 3000 nails to a steel wheel. Does it work? For a while, then the nails bend. We’ve seen this done by drilling screws through a tire, and that works much better; it’s less length for the screws to fulcrum over.

Aaay, we got a date for Sparklecon! It’s February 1-3rd in the endless suburban wastes of Fullerton, California. It’s in an industrial park, there’s a liquor store around the corner, and there’s a remote-controlled couch. Get on it.

Bose Wants You to Listen Up for Augmented Reality

Perhaps it is true that if all you have is a hammer every problem you see looks like a nail. When you think of augmented reality (AR), you usually think of something like the poorly-received Google Glass where your phone or computer overlays imagery in your field of vision. Bose isn’t known for video, though, they are known for audio. So perhaps it isn’t surprising that their upcoming (January 2019) AR sunglasses won’t feature video overlays. Instead, the $200 sunglasses will tell you what you are looking at.

The thing hinges on your device knowing your approximate location and the glasses knowing their orientation due to an inertial measuring system. In other words, the glasses — combined with your smart device — know where you are and what you are looking at. Approximately. So at the museum, if you are looking at a piece of art, the glasses could tell you more information about it. There’s a video showing an early prototype from earlier this year, below.

Does this make sense? Hard to say. A picture is worth a thousand words, so there are clearly some limits to what you can do with only audio. In fact, we’d dare say that despite the marketing phrase “Bose AR Enabled” the glasses aren’t really AR at all. It is more “position-aware audio.”

Of course, if you want to use them to listen to tunes, they’ll do that too. But so will earbuds and those will probably be more private. In fact, we were a little surprised these are built into sunglasses.

According to Bose:

From a technology perspective, the platform consists of truly aware audio devices that allow you to enjoy your digital audio alongside your real-world environment, a robust collection of sensors that enable a new heads-up, hands-free user interface, and developer libraries that enable partners to create new audio experiences in areas such as music, gaming, fitness, travel, and communications.

Battery life is 12 hours for standby and 3.5 hours for actual use with a 2 hour recharge time. The glasses are lightweight, but still quite a bit heavier than a conventional pair of sunglasses.

Unless a killer app appears, this looks like a swing and a miss. Earphones without cups and an orientation sensor doesn’t strike us as the next big product category. Then again, we aren’t marketing gurus, so maybe this is what every kid wants in their stocking. Remember, there’s no camera so you aren’t going to, say, look at a resistor and hear its value whispered in your ear.

If these were $25 or even $50, they might be a gimmicky replacement for headphones. At $200 we think it is a hard sell. If you want to do real AR, there are open source designs. The software is straightforward enough. Do you want these? Why? You could build your own version pretty easily? If you did, what would you do with it? Tell us in the comments.

Stove Alarm Keeps The Kitchen Safe

Gas cooktops have several benefits, being able to deliver heat near-instantly, while also being highly responsive when changing temperature. However, there are risks involved with both open flames and the potential of leaving the gas on with the burner unlit. After a couple of close calls, [Bob] developed a simple solution to this safety issue.

The round PCB sits neatly behind the knobs, affixed with double-sided tape.

Most commercial products in this space work by detecting the heat from the cooktop, however this does not help in the case of an unlit burner being left on. [Bob]’s solution was to develop a small round PCB that sits behind the oven knobs. Magnets are placed on the knobs, which hold a reed switch open when the knob is in the off position. When the knob is turned on, the reed switch closes, powering a small microcontroller which beeps at regular intervals to indicate the burner is on.

It’s a tidy solution to a common problem, which could help many people – especially the elderly or the forgetful. It integrates neatly into existing cooktops without requiring major modification, and [Bob] has made the plans available if you wish to roll your own.

On the other end of the scale, you might want an alarm on your freezer, too.

Generating Power with Wind, Water, and Solar

It is three weeks after the apocalypse. No zombies yet. But you do need to charge your cell phone. How do you quickly make a wind turbine? If you’ve read this project, you might reach for a few empty water bottles. This educational project might not charge your phone without some extra work, but it does illustrate how to use water bottles to make a workable air scoop for turning a crank and possibly generating electricity.

That takes care of the wind and water aspects, but how did we get solar? According to the post — and we agree it is technically true — wind power is a form of solar power since the wind is driven by temperature differences created by the sun. Technically true!

Short of an apocalypse, this probably isn’t a very practical project, but we liked it as a possible school project. Most of it can use scrap materials. The only things you might have to buy is a motor, some bearings, and some cheap nuts and bolts. You might even have all of it, depending on how much junk you hoard.

If you do use this as a student project, it is worth pointing out the duality throughout. The post talks about how a fan and a turbine are the same devices. It also uses a motor as a generator. In each case, you might design something for better performance when used one way or another, but a surprising number of transducers can operate in both directions. For example, speakers make poor but useable microphones. LEDs can sense light, as long as light can get to the die.

Now if you want to go all out, fire up your 3D printer. There are several possible designs.
