Microsoft’s Todd Holmdahl is heading up the effort to engineer scalable quantum hardware and software.


Microsoft has been on a quest to build the holy grail of computers for over a decade, dumping tons of money into researching quantum computing and the company says they are ready to transition over to the engineering phase of their endeavor. At least that’s what MS executive Todd Holmdahl aims to accomplish by developing the hardware and software to do so.


Like most cutting-edge tech development, nothing is set in stone and more often than not failure is a big part of the effort, something Todd is well aware of considering he was the person who spearheaded the Xbox, Kinect and HoloLens. As head of the team to bring about a scalable form of quantum computer, Todd is partnering with some of more renowned researchers in the quantum field including Leo Kouwenhoven (Delft University of Technology professor) and Charles Marcus (Niels Bohr Institute professor), both of which received funding from Microsoft to research theoretical topological qubit computing.



It’s all in the anyon braids, which form the logic gates that theoretically make quantum computing possible. (via MS)


To bring their quantum computer into reality, Todd and his team are turning to quasiparticles known as anyons, which will form the logic gates needed to perform computations. The problem with quasiparticles is that they are extremely unstable and tend to disintegrate in a matter of milliseconds shortly after being formed. Anyons by themselves exist in two dimensions and exhibit both an on and off state at the same time, however to make them stable and suitable for use in computing a third dimension is needed.


Hence the braiding, which is done by rotating the worldliness of a pair of anyons, which can’t be merged and therefore form a stable state and act as a logic gate. The team has already started to braid these anyons in the hopes of creating those logic gates that form the basis for quantum computing. Since the particles can exist in two states they can theoretically double the amount of computing power exponentially- so if one is capable of doing two calculations and two can perform four (and so on), imagine what a billion (or the equivalent amount of transistors found in today’s CPUs) can do!


On the software side, the team is working on trying to frame the software necessary to accompany topological quantum computing. So far, they have developed a series of tools to help them simulate a quantum computer in order to get a better understanding. The language they used to build the tools is called LIQUi|> (Language-Integrated Quantum Operations) with the characters at the end denoting how operations are written in math terms. The team hopes that using LIQUi|> will help pave the road to build the algorithms that can take advantage of quantum computers.


While they are making strides in their lofty endeavor, it will still be a ways off before quantum computing will come to fruition. My guess is that it will be another 10 to 20 years before they can produce a physical working model and probably several more before they can be manufactured on a larger scale. Still, it is exciting to see that we’re on the cusp of harnessing a computational power that used to be thought of a science fiction.

Even More Moto Mods!

Posted by Cabe Atwell Dec 26, 2016


Motorola is increasing its edge with modular phones by adding new snap-on Mods to its Z model, enhancing capabilities to include a range of features. An array of modular magnetic snap-ons to Motorola’s Z phone, which enhances the device’s capabilities to include a projector, camera lens, and high-powered charger (via


In an age where cell phones are falling in both price and reusability, the modular approach to capabilities taken by Motorola is refreshing. The idea is simple-modular phones allow for enhanced capabilities by adding more modules-in this case, Mods- that snap on to the back of a smartphone magnetically.


The modular component adds an additional feature while attached to the original device. So far, Motorola’s Z phone is leading the way with these features. Motorola claims that the Mods were designed with future generations of Moto Z’s in mind, so that if you buy a boombox feature or a lens feature for today’s current Moto Z, it will still work on the next model.


Additionally, to create each modular add-on, Motorola partnered with different industry leaders in design and engineering. The speaker Mod was created through a partnership with American electronics company JBL, and the camera Mod with optics company Hasselblad.


These are not merely gimmicks, but highly functional, high quality devices in their own right. As such, there are a few cons. Each Mod comes with its own battery, which charges independently of the smartphone. That means if you attach a Mod to a not-yet-fully charged Moto Z, and start charging, the juice first goes to the phone, then the Mod. It is possible to charge them separately, of course, but be aware that the Moto Mod system relies on battery power-and lots of it. That could be a reason why the latest Mod, a Mophie battery pack, came out recently. Providing 3,000mAh of power time, it clamps onto the phone as any other Mod, lengthening the time between charging. This feature is only another $80, and a carport feature, produced in partnership with Incipio, is only $65.


Motorola plans to produce even more Mods in 2017 than 2016, according to Moto Mods director John Touvannas. That has to make you wonder, what next? Are they going to invent needs we didn’t know we had, or come up with features that are actually useful? Possibly both. A call for solicitations from users resulted in some 380 pitches for new Mods, ranging from baby monitors to breathalyzers. If the Moto Mod team is able to take a new look at preexisting features, they could create enhanced features that offer something for everyone

Qualcomm processors will now be able to run Windows 10 giving the ability to run high powered Win32 apps. Qualcomm making the big announcement at WinHEC (Via Qualcomm)


Qualcomm made headlines a few months ago for making the biggest semiconductor deal ever. Now, they have another big announcement in store. Qualcomm and Microsoft are teaming up to bring Windows 10 to Qualcomm’s mobile processors. Thanks to this, Qualcomm’s Snapdragon processors will be the first ARM-based processors to fully support Windows 10. The announcement was made at WinHEC where attendees got to see a demo of the full desktop version of Photoshop running on a Snapdragon CPU via emulation. So why is this such a big deal?


Qualcomm’s chips, such as the Snapdragon, are high powered and are supposed to offer the best experience when it comes to streaming, watching movies, and even making phone calls. Most of the company’s processors are found on mobile devices and though they are powerful, most chips found in smartphones still aren’t strong enough to run energy consuming apps, like Photoshop and other Win32 apps. Bringing Windows 10 to these processors changes that. Qualcomm’s next generation of processors have the ability to run Win32 apps via x86 emulation on Windows 10.  As they showed in the demo, these chips will now be able to handle such high powered apps, bringing a desktop experience to your mobile device and stronger processors to standard PCs.


Both Qualcomm and Microsoft believe Windows 10 PCs powered by Snapdragon will be available as early as next year. Not only will the new devices fully support Windows 10, but they’ll also include Gigabit LTE, and superior Wi-Fi housed in a fanless design that’s meant to provide a long battery life. This is also big news for Microsoft because it may allow them to build a smartphone with the ability to run Win32 apps along with other UWP apps. Microsoft tried breaking into the smartphone game with its Windows phone, but it couldn’t compete with Samsung and Motorola. With Qualcomm on their side it could allow them to create something better and more powerful that the Surface Phone.


This isn’t the first time Windows attempted to run ARM devices. They previously gave it a shot with the OS Windows RT, but the results were not so successful. The biggest issue was ARM-based Windows programs were not synonymous with the standard 32 bit programs. Because of this, developers were forced to rewrite their programs to be compatible with Windows RT. Though some are still suspicious that the processor will run the apps via emulation, it’ll still be interesting to see if this will give Microsoft the break they need to finally create a successful smartphone. It could also give Qualcomm the support it needs to give Intel a run for their money.

Lime Microsystem’s LimeSDR features Snappy Ubuntu Core, allowing anyone to write their own apps for any number of projects. (via Lime Microsystems)


Back in June of this year, Lime Microsystems successfully funded their LimeSDR platform on Crowd Supply, garnering over $777K with a $500K goal. The company touted the board as ‘a low-cost, open-source, apps-enabled, software defined radio’ that can be used for everything radio- cellular base stations, media streaming, drone/RC control, IoT, you name it. What’s more, since the board is open-source in every way and outfitted with Snappy Ubuntu Core, users can write their own code or apps and share them with others in much the same fashion as the Raspberry Pi and Arduino communities.



Think of the LimeSDR as a development board for radio-based projects as it can handle a myriad of wireless communication standards including UMTS, LTE, GSM, LoRa, Bluetooth, Zigbee, RFID, as well as a wide frequency range of 100 KHz to 3.8 GHz. Lime’s choice of electronics makes it easy to use whatever standard you want as it features the company’s LMS7002M MIMO FPRF RF transceiver paired with an Intel/Altera Cyclone IV EP4CE40F23 FPGA, allowing it to carry out DSP (Digital Signal Processing) tasks on the hardware.


Rounding-out the LimeSDR is 256Mb of DDR2 of onboard RAM, a Cypress USB 3.0 controller, Rakon RPT7050A oscillator, 10 U.FL (6 RX/4 TX) connectors and a series of programmable LEDs. So what has been happening with Lime Microsystems since the successful crowd-funding campaign? According to a Crowd Source update, they are busy acquiring all the components needed to build the boards before they can ship them to those who pledged and are on course to deliver them all by the end of January of next year. Those waiting should check their email as the company will send a message the exact date their LimeSDR will arrive.


Lime Microsystems has also been recently lauded by Frost & Sullivan, who gave the RF company their Technology Innovation Award for their LimeSDR platform and “acknowledging the rising importance of programmable radio frequency (RF) in an increasingly software-driven world.” While there are many competing RF boards on the market, the main reason F&S bestowed their prestigious award to Lime was that none of the competition featured open-source hardware and software or was capable of a wide frequency range, noting that some of the other SDR boards even featured Lime’s RF transceiver chips.


While nobody has yet received their LimeSDRs, it will be interesting to see what the maker community does with them. Will there be a thriving code/app-based community shortly after launch or will it be sometime before there is significant shareware people can use for their projects?

A team from the University of Florida took inspiration from the popular franchise for a new type of wearable tech. The solar panels are integrated into the woven fabric (image via University of Florida)


Wearable technology is on the rise with the release of smartwatches and accessories like FitBit. But no one has quite gotten the integration of smart tech with clothing just right. There are still several kinks creators run into; bulky batteries, textiles that hold an electric charge, and comfort. One team from the University of Florida is trying their hand at wearable tech and it may be what we’ve been waiting for.


Rather than using chunky batteries, the team created solar power clothing with the ability to store the sun’s energy. They achieved this by making filaments that can be crafted into textiles, which then give them the ability to store and use the sun’s energy. The filaments are made out of flexible copper ribbons equipped with a solar cell on one side and an energy storing layer on the other side. It's a type of "supercapacitor" material. Which is genius, since the cap' can efficintly gather all energy generated from the solar cells quickly. With an entire shirt, let's say, all made of supercap material... the surface area of said capacitor would be enormous. The energy density they claim is 1.15mWh/cm^3 (and a power density of 243 mW/cm^3).


During the testing phases, the team sewed them into a square piece of yarn, which can then be sewn into jackets or other outwear to get energy to power devices, like phones. This new tech improves on the major limitations of solar cells. Traditional cells are limited in their portability since they have to store the energy they produce in battery or have it flow into a power grid.


solar clothes 3.PNG


Believe it or not, the inspiration behind the tech was actually taken from the popular Back to the Future franchise, specifically the self-lacing Nikes from the second film. Along with this, they also had the military in mind. Soldiers overseas are at a risk of extreme exhaustion and heat stroke from carrying over 30 pounds of batteries in the hot sun. This new wearable tech will relieve some of the weight by eliminating the batteries completely.


Aside from being used for the military, the team believes the technology can be used for other things, like electric cars. Because the solar cells can be integrated easily into fabrics, are portable, and don’t rely on chunky batteries, it could be the breakthrough wearable tech has been looking for. Imagine wearing a coat or hoodie with the ability to charge your phone. No more freaking out over low batteries or carrying around battery banks. It’ll be exciting to see what the team can do with the tech in future. For now, make sure to keep your phones properly charged.

A team from UC San Diego used old tube technology to create a chip without semiconductors. This is what the semiconductor free chip would look like. (Image via UC San Diego)


The fashion world is proof that old is new again. How else can we explain ‘overalls’ becoming popular again? But it seems that concept is not an exclusive one – it’s coming to the world of technology. Thanks to new research from the University of San Diego, vacuum-tubed powered computers will be making a comeback.


Researchers from UC San Diego used vacuum tubes to create the first semiconductor-free, laser-controlled microelectronics device, which uses free electrons. This groundbreaking discovery could lead to better solar panels and faster microelectronic devices. Though it is old technology, the vacuum tubes proved to be more effective because they don’t have the same limitations as semiconductors based on silicon and other materials.


Traditional semiconductors cause the electron velocity to be limited due to its resistance of the materials. The electrons also need a zap of energy is needed to get them pulsing through the band gap, which is caused by insulating properties, like silicon. Vacuum tubes dodge these problems since the electrons can be dislodged to carry a current through space. But this doesn’t mean vacuum tubes don’t have their own problems. They require over 100 volts or a powerful laser to knock the electrons loose. The researchers at UC San Diego tackled this problem head on and found a solution in building gold mushroom like nanostructures with parallel gold strips. Combining this with a lower amount of voltage, the electrons were easy to dislodge.


So what were the results? Using the vacuum tubes showed a 1000 percent increase in conductivity. This leaves more electrons available for manipulation. Because of this the tubes can act as a transistor, power amplifier, or photodetector, which are all things semiconductors do. But the tubes will work with less resistance and the ability to handle higher amounts of power.


Right now this is just a proof of concept. There’s still a lot that testing researchers have to do to ensure these vacuum tubes will actually work for the long term. Dan Sievenpiper, the author of the research paper published in Nature, says the next step for the team is to understand their limitations and how far they can be scaled. The team also wants to test the applications in electronics, environmental applications, and even weapons.


The research sounds promising. Hopefully, this application will move from proof of concept to actually being used to make devices, like solar power panels, faster and more efficient. Then maybe more people will be convinced to switch over to solar power for their energy.

TI INA301EVM - "High accuracy, high slew-rate current sense amplifier with integrated high-speed comparator optimized for overcurrent protection."
TI INA301EVM - "High accuracy, high slew-rate current sense amplifier with integrated high-speed comparator optimized for overcurrent protection."


I saw this board and thought it was pretty useful... see why below...


Need your SBC to sense current somewhere in a DC circuit, what’s the best way to do it? Yes, you attempt to make a circuit to do so… or you can just save the time and buy one. I’m a big advocate of “not building a project before building a project.” You want your SBC or MCU to sense current for some reason, not spend any amount of time creating and troubleshooting a way.


I saw this board from TI and thought it would make a good addition to one’s dev board cache. Very few kits I’ve come across has any way of sensing current.


The TI INA301EVM (an evaluation board) is a current sensing device that amplifies the voltage measurement across a chosen shunt resistor in line with the current source. This analog output device amplifies the signal so that it is suitable for a microcontroller to read its input to an ADC. The INA301 (series) can operate on a supply voltage from 2.7V to 5.5V while operating up to 36V on its input.


When measuring current from a device or wire/trace, the voltage is read across a shunt resistor from 0V to 36V range. The output has 2 settable modes, via the reset pin hooked up to one of the GPIO pins of the microcontroller, set high or low.


The first mode is transparent mode, which the analog out follows the analog in signal, which is intended to be connected to the ADC pin. The other mode is latched mode. Where an alert can be set using the value of the Rlimit resistor, when an overcurrent is detected, the ALERT pin is pulled low for the microcontroller to detect on its GPIO pin. To determine your Rlimit resistor value, You choose the voltage threshold for the voltage to trip at, using Vlimit in the following equation:

Threshold limit-setting resistor value,  RLIMIT = VLIMIT / ILIMIT

  1. 4 V / 80 µA = 50 kΩ



The device has an excellent temperature range from: -40 C to 125 C


Low supply current consumption: at 700uA


The elavuation board has 3 different differential amplifiers. 20, 50, 100-V/V gain. Why do you need this? In case the resulting voltage measurement off the current sense resistor is too low to read for the system.



Application and use: 

Battery Monitor

This device can be used as Battery Monitor where a microcontroller is using the analog output of the INA301 to measure battery current consumption overtime.


Power Supply

Current monitor with alarm, the microcontroller can monitor the alarm pin of the INA301 and go into shutdown or sleep when current consumption is too high. This alarm function can also be used as a signal to turn other devices on and off based on the set current alarm.

The Chipsetter ONE is an automated pic-and-place machine that assembles PCB electronics using component trays and an array of tape feeders that can utilize different sized SMTs. (via Chipsetter)


Anyone who has ever assembled their own PCBs can tell you that it’s a time consuming process that becomes a monotonous nightmare if you have to assemble more than one. Those who prefer to farm that chore out to a manufacturer can tell you that often times it’s costly and can take weeks to receive them depending on how many are needed.


In an effort to alleviate those issues, Chipsetter has designed a desktop pick-and-place machine that can assemble PCB electronics in-house in a matter of minutes. In fact, the Chipsetter ONE makes it easy to switch over to different PCB jobs as the tape feeds are modular and can be swapped-out on the fly depending on user’s needs.



Chipsetter designed the ONE using an automated vacuum head that’s outfitted with dual articulated arms that are capable of picking and placing two electronic components at a time with a size ranging all the way down to 0402. It has a placement speed of up to 1250 component placements per-hour and can accommodate boards of up to 13.5 X 10-inches.



The Chipsetter ONE can handle up to 40 8mm tape feeders at a time as well as components from cut-tape and tube packages. I like what I'm seeing here...


As far as tape feeders go, the ONE can handle up to 40 8mm feeders as well as 12 and 16mm feeders as well. Components can also be supplied using cut-tape, tube packages and JEDEC/custom trays- or even a dual combination of package platforms. The pick-and-place machine has an accuracy of 30-microns thanks to a pair of cameras, situated above and below the 8-position auto-tool changer, making it incredibly reliable with component placement. The top camera actually inspects and corrects component alignment while the bottom corrects any misalignment with in-place components.


On the software side, the platform handles everything so there is no setup or programming needed, even for different circuit board projects. Users simply send the manufacturing data, including Centroid and BOM files (in .csv format) from their favorite EDA platform to the machine and it does the rest.


There are a few drawbacks to Chipsetter’s ONE, as users need to apply the solder paste manually, which can get messy if not done correctly. Users also need their own reflow oven, as the ONE does not come equipped with one. This makes it hard to justify the price tag, which comes in at just over $3,500 US. Makers who manufacture several circuit boards per year probably would not benefit from using this machine, however small businesses who churn-out dozens per-year would probably find it beneficial from producing their PCBs in-house.


Chipsetter is currently coming to an end of an unsuccessful Kickstarter campaign to manufacture the ONE with reaching only $66,714 of their target goal of $104,895 and it’s uncertain if those interested will be able to get their hands on one in the near future.

The team at the university uses voxels and ultrasound waves to keep the pixels floating in mid-air. These pixels are actually floating in mid-air (via University of Sussex)


With most of our times spent staring at screens, the clear, crispness of displays are important. Every year devices seek out pixels that are better and make for the ultimate viewing experience. But what if the pixels floated in midair? The University of Sussex has created an experimental display, dubbed JOLED, made of a grid of voxels that measure 7x6 voxels high and wide. That’s not the mind blowing part. The voxels look like multi-colored spheres that float in mid-air.


Looking at the testing footage, it looks like a magic trick or CGI footage, but this is very real. The spheres stay in the air by ultrasound speakers that put out high-pitched and high intensity soundwaves, which are inaudible but forceful enough to keep the spheres in the air. The pixels themselves are coated in titanium dioxide, which gives them an electrostatic charge which allows them to be manipulated in mid-air with a change in the electric force field.


So what can this technology be used for? The team at Sussex is currently testing how the display can be used to provide on-demand media. They see it as a screen appearing in front of the viewer and then the objects fall to the ground once the video is finished. They also want viewers to be able to interact with it. Sounds like something out of The Matrix. The team also wants to up the pixel density along with the colors displayed.


It’s definitely cool to see these pixels float in the air looking like it was created with movie magic. But don’t expect to see the display for yourself anytime soon. The team still has a lot of work to do before they make this technology a reality. Recently, the team presented their findings at Japan’s ACM User Interface Software and Technology Symposium. This technology could lead to new possibilities for media, including mobile and game designers. 


Who knows, this is what our displays could look like in the future. For now, we’ll have to shell out a lot of cash for those flat old 4K TVs. Or.. is it time to dust off the CRT?

Russian and European scientists believe T-rays will be faster than electromagnetic fields when running computers. Will T-rays make our computers faster?


No one looks forward to going to the airport and in recent years the experience has been more unpleasant thanks to TSAs. Security is important, but there’s a sense of dread and unease when walking through a body scanner. But while getting scanned to make sure you have the proper sized shampoo, did you ever think the TSA technology could be used to speed up your computer? Russian and European scientists are currently testing the method and published their findings in Nature.


No matter how fast your computer is, it can always be faster. Memory is what keeps our computers from being lightning fast. Memory cells on a PC are switched via an external magnetic field, but it’s not necessarily the fastest method. But this new process proposed by scientists would forego that. Rather it would use terahertz radiation (T-rays), the same ones found on airport bdy scanners. The T-rays could speed up the rate at which cells reset by a factor of 1000. This could then be used to make faster memory.


T-rays (Terahertz-driven anisotropy fields) emit a series of short electromagnetic pulses that hit the cells at high terahertz frequencies making them faster than the average electromagnetic field. But don’t expect to find t-rays blasting through computers any time soon. Scientists are still testing the method. So far they’ve tested it on a weak ferromagnet, thulium orthoferrite (TmFeO) with great success. The results also showed the T-rays’ effect was ten times greater than the external magnetic field making this method faster and more efficient. But the T-rays have yet to be tested on computer memory cells. You’ll have to wait on getting a super speedy computer.


Because T-rays can dish out quick, precise scans of organic and mechanical material, they have other uses as well. Some proposals include looking for weapons inside of luggage, scanning broken microchips, and looking into fragile texts. If this method does actually work on computer memory cells, it would be a huge improvement for high performance computers. Even the tiniest boost could make a big difference depending on the application. Scientists are still working out all the kinks but hopefully we’ll have an update on this development soon.

A research team at the University of Colorado-Boulder is using wastewater from breweries to help cultivate ion battery electrodes. A diagram of the process researchers use the wastewater (Photo from University Colorado-Boulder)


For some, beer is the ultimate refreshment, but thanks to researchers at the University of Colorado-Boulder, it can also be a power source. Researchers have found a way to transform brewery runoff into low-cost lithium-ion battery electrodes. Talk about getting a buzz. This is a great way to recycle the waste. When a brewery makes a single barrel of beer it takes around seven barrels of water to make it. The wastewater then has to be filtered before it’s thrown out, which also costs brewers money. Using the waste to cultivate batteries not only recycles the matter, but it saves money as well.


The process of using the wastewater for ion batteries is similar to beer making according to the Colorado researchers. They cultivate the feedstock in wastewater, which produces Neurosporacrassa, a fast growing fungus. This sugary fungus can then be used to make anodes for the ion batteries. The researchers say the wastewater is ideal for the fungus to grow in. The wastewater also helps researchers note the fungus' chemical and physical processes from the beginning.


Researchers are in the testing phases with the process now, but as long as tests prove successful it has the potential to be used on a wider scale. This process could help breweries limit their wastewater costs and manufacturers would have access to an incubating medium for battery technology components that are cost effective. So far, one brewery is one board with the research team: Avery Brewing in Boulder. This new partnership will allow the team to test the process on a wider scale. The team, led by Tyler Huggins and Justin Whiteley, recently took part in the finals of a US Department of Energy-sponsored incubator competition at the Argonne National Laboratory in Chicago.


Recycling wastewater to help ion batteries is a great step forward in helping to reduce waste on the planet. This process prevents the waste from just sitting in giant vats in the brewery. It also saves them money and happy breweries make for tastier beer, probably. Who would've thought beer could actually be used to make batteries. And you thought the best thing they did with beer is make fried foods with it.

Yoyogi National Gymnasium replaced the wooden floor with 400sqm of SEfl LED Video-flooring from Glux. (via rentGlux)


The B. League basketball games in Tokyo have kicked off with the first beginning with Alvark Tokyo against the Ryukyu Golden Kings at Tokyo’s Yoyogi National Gymnasium. The game itself is just like any pro basketball game, however the MVP in this case isn’t the best player but rather the court itself as the traditional wood planks have been replaced by LED display panels.

All of the sections of the court, including the center circle and free-throw lines are prominently displayed just like any regulation court but that is where the similarities end as graphics and animations are projected on the floor when something significant happens in the game.


For example- during the tip-off both team names encircle the center circle and explodes away during the jump. A successful 3-pointer will result in number 3 graphic and dunking results in an explosion and/or the player’s bio displayed on the court. What’s more, players can be tracked with tracer lines and circles that follow them as they traverse up and down the court.



The court itself is made up of 1,680 individual displays that are about 20-inches from edge to edge, measuring out at 400sqm. The panels are actually a product of China-based Glux who are known for their creative LED displays, which were prevalent for the opening ceremony of the 2008 Olympics in Beijing, the 2010 Shanghai World Expo and the 2010 Singapore Youth Olympics.



For the Yoyogi Gymnasium, Glux used their SEfl LED Video-flooring, which has a pixel density of up to 36,864 (dots/m2), a refresh rate of 1MHz and a contrast ratio of 2000: 1. Each panel is covered by a transparent PC ABS protective mask and is made using a strong waterproof carbon fiber frame, making it incredibly durable and able to withstand over 1,000 pounds and great for playing basketball on.



Workers installing the SEfl LED flooring, which is done in the same fashion as some anti-static tile floors found in server rooms.


The LED flooring is installed in almost a similar fashion as some modular anti-static floor tiles found in server rooms, which uses aluminum floor beams to connect each panel while metal latches lock them in place, making it easy to switch out panels if problems arise. Each LCD panel also has its own power supply built in as well as a CAT6 port to interlock the panels together for use as massive single display or a ton of smaller ones, all of which can be controlled using a single laptop or PC.


As the video shows, the end result of putting together a bunch of LED floor panels is certainly impressive but I have to wonder if it interferes with the players. Blinding isn’t a problem as each LED display has a film over the ABS protective mask to subdue its brightness and glare but I can’t help wondering if they get motion sickness during animations.

The Invader mixes an old school turntable with a embedded record

(Photo from Thud Rumble)


Hoping to do something similar to this with a Raspberry Pi, but in the meantime....


The art of DJing has been around since the late 70s. Over time the art form has evolved and adapted to new technology. Some find the use of computers in DJing an innovation; others see it as lazy and prefer the old school way. But both methods offer something different the other doesn't have. Isn't there a way to bring the best of both worlds together? A group of DJs may have answered the call with their latest turntable, The Invader, which features a mixer and an embedded computer.


The project is created by DJs Qbert, Yogafrog (Ritche Desuasido), Rich Johnson (DJ Hard Rich), and Killa-Jewel (Julie Fainer). They had the idea four years ago when their company, Thud Rumble, was having an open house and Rich Johnson expressed his desire to make a mixing machine for them. The dream is now a reality. Showing off prototypes at Intel's IDF keynote, The Invader looks like an old school mixer with a touchscreen display running Windows 10. The turntables run on the company's own Traktor mixing software, but any DJ app that runs on Microsoft's OS will work.


The prototypes are pretty tall, but the company wants to make it no taller than two centimeters so it'll easily slip inside a backpack. The turntable has standard features found on most mixing board, like faders in the middle of the board and volume controls for each deck above. There are also eight buttons along the side a DJ can set up to play different cuts in a song. The board runs on Intel i5 and i7 processors, if you couldn't guess, and comes with additional HDMI for video mixing. Currently, there's no soundcard, but the company are working with Native Instruments for a future audio interface.


The Invader is still in the early phase of development and the creators are looking to add more features. The printed circuit board needs to be finalized along with the standard audio ports. These ports allow you to switch to phono so you can scratch actual vinyl. The Invader also gives you some customization choices from laser-etching options to choice of rubber or old school arcade buttons for video game enthusiasts. So what is the price for this new turntable? It'll be priced at $1,699. It sounds like a lot, but compared it to the Pioneer DJ DJM-S9 mixer for Serato, which costs the same without the built-in computer. The Invader will ship at the end of the year.


This turntable is an innovative way to mix the old school with the new. And best of all, it lets you have the best of both world without having to lug around a laptop. Macbooks may be light, but why risk bringing all that data around with you? The Invader gives you everything you need in this all-in-one turntable. But this doesn't mean it could pose some problems. For one, most DJs use mixers provided by venues. Some may not have an issue with bringing their own mixer, but others may not want to do so. Also, with a laptop you have instant access to your songs and mixes. With this turntable you may have to move your songs to the embedded computer. Hopefully, the songs will be easily accessible. Either way, it's a new way to think about an artform as old as Djing.

If you’re looking for a quick and simple way to convert your ECAD files into MCAD, you may want to check out (now part of the Autodesk empire). What’s more, users can view and manipulate the models in 3D as well as modify those models in a limited fashion i.e. hiding unwanted objects and changing-out simple components. Once the 3D model manipulation is complete, it can then be downloaded in several different formats for use on most MCAD systems. was actually designed by the creators of CADSoft and wanted a simplistic system for engineers that wouldn’t break the bank, didn’t take forever to install and didn’t require a Ph.D. to use. Their intention was to make the data-language bridge between ECAD and MCAD as simple and straightforward as possible over a web-based platform using desktop or online CAD tools. is capable of reading/writing in a number of different formats in order to be compatible with a number of different ECAD and MCAD systems. As it stands now, reads IDF 2/3 ECAD interchange formats as well as the IPC-2581 format and Cadsoft Eagle files. As far as writing goes, it uses STEP and IGES 3D data exchange file formats, allowing different format files to flow back and forth with relative ease.


It is also compatible with most every CAD system on the planet, including CadSoft Eagle, A host of Mentor suites (BroadStation, Expedition, etc.), SolidWorks and PTC Creo just to name a few. A complete list of systems can be found here ( As far as features go, has a simplified built-in component library and simple tools to help position them on the 3D model. If users need a specific component that is not listed in the library, it will then offer a suitable replacement based on the original components name, size and type. Of course, users can always substitute their own if they prefer and even save them in’s library for future use.


Security for isn’t the best in the world, but it is effective as far as online browser-based platforms go. Is anything online truly secure? Once a model is uploaded, the platform extracts the necessary data from the shape of the PCB and component layout from the file and then deletes it. The board’s data is then compressed and encrypted before being stored for later use. The user can also delete that data file if the need arises.


Is an end-all conversion and manipulation tool for producing ECAD/MCAD models? No and it was never meant to be but it can come in handy, especially when subtle model adjustments and conversions need to be done quickly and remotely. Since it’s browser-based, you can use it anywhere, making it a versatile tool to keep handy when away from home.
