Fingerprinting is an important element of crime scene investigation. You may have heard that Superglue (cyanoacrylate) can be used to develop fingerprints. But you might not be aware that this technique can easily be performed at home with everyday materials. So in this project, I am going to teach you how to develop fingerprints with the Super Glue fuming method.

Neuroscientists and engineers at the University of Waterloo's Computational Neuroscience Research Group have built the world's largest functional model of the human brain. Named Spaun or the Semantic Pointer Architecture Unified Network, the simulated brain has a 784-pixel digital eye for visual input, and a robotic arm that scribes tangible output.
In this week's headlines: NASA is sending a 3D printer to the International Space Station to be used for printing spare parts and tools. BMW has its first all-electric hatchback called the i3. The car offers an 80 to 100 mile range and multiple eco-friendly, low energy options.

Dave shows you how it's not that hard to find that mythical $50 analog oscilloscope on ebay. At least in the US and UK. It's not impossible, it turns out. For more, check out: http://www.eevblog.com/forum/blog/eevblog-498-how-to-get-a-$50-oscilloscope-on-ebay/
In this week's headlines: Drone It Yourself turns random objects into RC quadrotors: A Drone It Yourself project turns just about anything into a quadrotor drone with the addition of a few motors and a control unit. Twinkind 3D photo booth scans your body in a flash: A company called Twinkind in Hamburg, Germany is offering a 3D portrait service that creates your very own mini-me.
A recent paper by researchers in the Built Environment Research Group at the Illinois Institute of Technology announces some troubling news for at-home and cubical rapid prototypers; the emission spewing from desktop 3D printers could be releasing harmful nanoparticles.
The Omron D6F-PH MEMS differential pressure sensor is compact and provides high-accuracy with superior resistance to environments. High accuracy of ±3% RD, linearized and temperature compensated, digital output (I2C communication), and high flow impedance to reduce the influence of bypass configuration...
This episode features: Researchers at the University of Bath are developing a device that trains the brain to turn sounds into images, which could be used as an alternative to invasive treatments for blind and partially-sighted people.
What is an FPGA, and how does it compare to a microcontroller? A basic introduction to what Field Programmable Gate Arrays are and how they work, and the advantages and disadvantages. FPGA Stuff in Dave's Amazon store: http://bit.ly/1ayoNiV
Silvia Todd is launching her first Kickstarter campaign at the age of 12 after designing a painting robot. To make her idea a reality, Silvia approached Lenore Edman and Windell Oskay at Evil Mad Scientist Laboratories (EMSL), a Silicon Valley company that designs and produces specialized electronics and robotics kits.

Today on Engineering Newswire, brought to you by Interpower Corporation, we're mapping blood vessels to recognize your face, spicing up swamps with robotic frog mates, and swimming with the robotic fishes, literally, not figuratively, no one died.
A robotics team from the University of Queensland has created two versions of a single-use UAV. The unmanned aerial vehicles, which are usually associated with clandestine military operations, are both designed to relay environmental information.
