Digits is a wrist-worn sensor that recovers the full 3D pose of the user's hand. This enables a variety of freehand interactions on the move. The system targets mobile settings, and is specifically designed to be low-power and easily reproducible using only off-the-shelf hardware. The electronics are self-contained on the user's wrist, but optically image the entirety of the user's hand. This data is processed using a new pipeline that robustly samples key parts of the hand, such as the tips and lower regions of each finger. These sparse samples are fed into new kinematic models that leverage the biomechanical constraints of the hand to recover the 3D pose of the user's hand.
Flexible screens, wearable computers, conductive ink, wires that move like muscles: These are the materials that will make up the gadgets of the future, and they’re being dreamed up and developed in do-it-yourself hacker labs and garages all around the world. Sure, large manufacturers are working on these kinds of materials, too, but openMaterials co-founder Catarina Mota says the real innovation is coming from the bottom up as makers, hackers, and DIY enthusiasts figure out how to do “the future” for themselves in their own home labs. Smart materials have one or more properties that can be changed by external stimuli, such as temperature, moisture, a magnetic field, or an electric current. And these kinds of materials are changing how we think about hardware and what hardware is able to do.
HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone's headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation. HiJack has been tested with the iPhone 3G/3GS/4G, iPod Touch, and iPad devices. Power. The HiJack energy harvester can supply 7.4 mW to a load with 47% power conversion efficiency when driven by a 22 kHz tone from the output from a single audio channel on the iPhone 3GS headset port, all using electronic components that cost just $2.34 in 10K volumes.
A Tens machine is used to provide a drug free way of removing pain from your body ( TENS stands for Transcutaneous Electrical Nerve Stimulation ) .Here I will show you how to build your own Tens machine and reduce the amount of pills you use to stop pain .To Build this Tens unit, you will first need to buy a 555 timer IC . The 555 timer is very small about a quarter of the size of your finger nail .You can purchase one for about 25p from Maplins or Radio Shack etc . There are 2 types of Tens machine. High Frequency Tens uses frequencies in the range of 80 to 100 Hz. This blocks the pain impulses going to the brain . Low frequency Tens uses frequencies from 2 to 4 Hz .
Introducing the next big thing in tech-world: Android Arduino open accessory development kits. Do you have a great idea for an Android accessory? Then this Seeeduino Android ADK main board is the go-to choice for DIY’ers everywhere. Using the Seeeduino, you’ll be prototyping your custom designed product in mere hours.
[Gil] recently wrote in to tell us about some awesome research going on at UCLA. Apparently by layering some oxidized graphite onto a DVD and tossing it into a lightscribe burner, it’s possible to print your own super capacitors; some pretty high capacity ones at that. For those that are unaware, supercapcaitors are typically made using two electrolyte soaked, activated carbon plates separated by an ion permeable film.
A team of international researchers have created graphene supercapacitors using a LightScribe DVD burner. These capacitors are both highly flexible (pictured below) and have energy and power densities far beyond existing electrochemical capacitors, possibly within reach of conventional lithium-ion and nickel metal hydride batteries. The team, which was led by Richard Kaner of UCLA, started by smearing graphite oxide — a cheap and very easily produced material — films on blank DVDs. These discs are then placed in a LightScribe drive (a consumer-oriented piece of gear that costs less than $50), where a 780nm infrared laser reduces the graphite oxide to pure graphene.
In an industry where energy density tends to increase five percent a year, our achievement of more than doubling state-of-art energy density and lowering cost by half is a giant step towards realizing Envia's mission of mass market affordability of a 300-mile electric vehicle. Atul Kapadia, Envia Systems Chairman & CEO Since the inception of Envia, our product team has worked tirelessly and logged over 25 million test channel hours to optimally develop each of the active components of the battery: Envia's proprietary Si-C anode, HCMR cathode and EHV electrolyte.
In this interview, shot in Shanghai, I interview Ricky Ye, the founder of DFRobot , on some interesting aspects and real-world applications of Arduino , the easy-to use hardware platform with a simple programming interface. If you’re a software dev that’s always been just a little afraid of hardware (like me), check out our conversation and you’ll likely get cured. And then go read up on Processing . It’s even simpler than Java. (If you’re interested in learning more about Hackerspace Shanghai, where this was filmed – you can find it here .)
From Wiki Introduction HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone.
Here are various projects we are hacking on, have already done, or (further down the list) just occurred to us. Check out also the list of stuff you can try out in brmlab yourself . If you need something special for your project and you think that hackerspace would not mind to buy it or some of our members can find it at home, you can let us know on Equipment wishlist (and/or IRC and mailinglist) - just make sure that we do not already have it (check Equipment page). You are very much invited to ask around to gather support, interested people, ideas and advice for your projects, and we're looking forward to hearing about your progress, or seeing it by our own eyes in the hackerspace or at least on some meetup. Want to create a project ?
A sample of the OLED roof panel material, that can switch between being transparent and emitting light Image Gallery (2 images) What if your car had roof panels that let you see the sky during the day, but that lit the interior of the vehicle at night? This is now a distinct possibility, thanks to work being done by BASF and Philips.
As architectural design becomes more and more sophisticated, glass is playing significant role in building construction and decoration. It leads to a diversified demand in laminated glass, not only in safety and security purposes, but also aesthetics, design, art and view control etc. One of the most popular bonding interlayer films, nowadays, used for glass lamination is PVB. Despite PVB is expansive, PVB is delicate to handle.
