This glove is something of a medical breakthrough. It's used in conjunction with a musical keyboard to teach the wearer how to play simple songs. The thing is, instrumental proficiency isn't the end goal. This is aimed at returning sensation to patients who have had a spinal cord injury. Many of the test subjects -- all of which had the injuries more than a year before participating -- experienced … [Read more...]
This rather normal-looking power strip hides a secret inside. It's called the Power Pwn, and it conceals hardware which facilitates remote penetration testing of a network. It really is the ultimate in drop hardware as you can quickly swap it with existing power strip. Who's going to question it? It's got almost all the bells and whistles. There's dual Ethernet ports, Bluetooth with 1000' … [Read more...]
This system of hybridizing your home's electric appliances is an interesting take on solar energy. It focuses on seamlessly switching appliances from the grid to stored solar energy as frequently as possible. There's a promo video after the break that explains the setup, but here's the gist of it. Follow along on the pictograph above. We start on the left with solar panel. This feeds to a … [Read more...]
[Shahriar Shahramian] is playing with some liquid nitrogen in order to see how various components react to extremely low temperatures. After the break you will find forty-one minutes of video in which he conducts and explains each experiment. This does have practical applications. If you're designing hardware for use in space you definitely need to know how the hardware will be affected. We've … [Read more...]
For their recent high altitude balloon project LVL1 member [Brad] programmed a pretty complicated brain based on an Arduino. It was responsible for collecting data from all of the sensors, and reporting back in a few different ways. One of the things he did to simplify the project was develop a task scheduler for the Arduino board. It lets you add functions to a queue of jobs, along with data … [Read more...]
The Stylophone - a musical toy from the 60s - is a surprisingly simple piece of engineering. With a simple metallic keyboard played with a stylus and just a handful of transistors, the Stylophone was able to produce a few marvelous for their time sounds, and is the equivalent of a pre-[Stradivarius] violin for the electronic music scene. [Simon] tore apart an original Stylophone, and did a … [Read more...]
[Dave] noted that in a recent poll of FPGA developers, emacs was far and away the most popular VHDL and Verilog editor. There are a few reasons for this - namely, emacs comes with packages for editing your HDL of choice. For those of us not wanting to install (and learn) the emacs operating system, [Dave] got Notepad++ to work with these packages. Notepad++ already has VHDL and Verilog … [Read more...]
