We (Procept) are looking for an engineer who has experience in the implementation of filtering and compensation techniques for inertial platforms (especially those involving the use of MEMs based gyroscopes and accelerometers).
The candidate must have had practical experience in such systems and have a high level of proficiency in both the mathematical and practical aspects of such a system.
If you believe you have the skills required, please apply and provide details on the relevant practical and theoretical experience you have.
Note that while the company is based in Australia, this is expected to be a role which can largely be carried out remotely. Note also that as this will be a contract position, you will need to be appropriately registered to provide such services. Please provide confirmation of this in your application.
Detroit-based visual artist Bethany Shorb’s “Supplemental Restraint System” is born from classic American and vintage European sports car parts harvested from wrecked vehicles. Her work is tightly wrapped in an outer skin made exclusively from previously deployed airbags, beaded and sutured back together forming another protective barrier in an imagined automotive crash narrative, then further fetishized in glass scientific vitrines. Also included in the show are neon and automotive emblem text assemblages as obsessive tropes on car-culture.
Holding an MFA from Cranbrook Academy of Art, New York area native Bethany Shorb has dabbled and excelled in disciplines ranging from sculpture, to fashion and graphic design, to photography, to multimedia and music. She has performed around the country as Toybreaker and as half of DethLab. As founder of Cyberoptix, she has designed a vast catalog of innovative couture, including the costumes for Skinny Puppy’s 2004 world tour. Some of the more complex, custom made ties are made with deconstructed vintage, recycled or other environmentally sustainable materials. Her work has been featured in various design blogs and print publications such as The New York Times Style Magazine, Details, Fiberarts, Bust, BPM, Adorn, and Industrial Nation.
THIS month’s chemical section is dedicated to that noble and glorious purpose of celebrating the Fourth of July in noisy fashion—and with cannon crackers and colored fire that can safely be made in your own lab. However, before plunging into a pile of recipes and formulas it is necessary to warn you fellows to be extremely careful in preparing these mixtures. In themselves they will not blow up until brought into actual contact with fire or through extreme friction, but remember always that you are working with explosives—regardless of how mild they may be away from fire.
To overcome the dangers of friction it is well to mix your powders in small doses. A simple way is to put them on a sheet of fairly substantial paper and, by picking up two ends, rolling the powder back and forth as you raise and lower your hands alternately. But where you must use your pestle and mortar—watch out for friction!
Ever wake up one morning and say “today, I’m going to design my own banknote”? Of course, we all have. But earlier this week, I decided to act on that impulse. And just last night, I printed and laser cut my first batch of bytecoins at Metrix.
Although I did get some nice shots, I couldn’t help but feel that they don’t quite capture the full experience of a real live lightning machine. While I can’t do much to recreate the visceral smell of ozone and nitrogen compounds formed by the ionizing sparks, or the reverberating whine of the beautiful but deadly spark gap, I did have an idea for bringing another aspect of the lightning show to the interwebs.
Why that particular camera? Partly because I found someone dumping a bunch of them on eBay for cheap, but also because they run CHDK, the infamous scriptable firmware for Canon cameras. This let me write some code to streamline the process of taking ten photos all at once, and then get them off of the cameras in a reasonable manner. By wiring all of them to the same 10-port USB hub, and using CHDK’s syncable USB remote feature, I was able to wire up a single button to make all of the cameras fire at once. Collect all the photos, find all of the good ones that are actually in focus, get them aligned and color balanced and scaled, and away you go. Bullet time lightning.
On Wednesday’s NewsHour, science correspondent Miles O’Brien looks at a growing effort to get kids more enthused about science, engineering and math: “Maker Faire” in San Mateo, Calif. It’s an event where scientists, engineers and builders converge every year to celebrate building cool things, and a playful love of invention.
U.S. students have been lagging behind internationally, when it comes to science and math education. So far behind, it’s been called a STEM crisis. (STEM is short for science, technology, engineering and math.)
While at the Maker Faire, Miles caught up with Adam Savage, co-host of “Mythbusters,” whose work is as close to the “Make” ethos as you can get.
While metallic inks have been used to manufacture electronic devices using inkjet printing technology, the silver pen offers users the freedom and flexibility to construct electronic devices on the fly, says Jennifer Lewis, the Hans Thurnauer professor of materials science and engineering at the University of Illinois who led the research team along with Jennifer Bernhard, a professor of electrical and computer engineering.
“The key advantage of the pen is that the costly printers and printheads typically required for inkjet or other printing approaches are replaced with an inexpensive, hand-held writing tool,” said Lewis. “This is an important step toward enabling desktop manufacturing (or personal fabrication) using very low cost, ubiquitous printing tools.”
For everyone who finds mathematics incomprehensible, boring, pointless, or all of the above, Glen Whitney wants to prove you wrong.
He believes that tens of thousands of visitors will flock to his Museum of Mathematics, to open in Manhattan next year, and leave invigorated about geometry, numbers and many more mathematical notions.
“We want to expose the breadth and the beauty of mathematics,” said Mr. Whitney, a former math professor who parlayed his quantitative skills into a job at a Long Island hedge fund. He quit in late 2008 with connections to deep pockets and a quest to make math fun and cool.
Two years ago, he and his team built a carnival-like traveling exhibit called the Math Midway, a proof-of-concept for the coming museum. It includes a tricycle with square wheels of different sizes that visitors can ride smoothly around a circular path ridged like a flower’s petals. An accompanying sign explains why: The undulating circular surface rises and falls exactly to offset the odd shape of the wheels, so that the tricycle’s axles — and the rider — remain at the same height as they move.
These LED strips are fun and glowy. There are 32 RGB LEDs per meter, and you can control each LED individually! Yes, that’s right, this is the digitally-addressable type of LED strip. You can set the color of each LED’s red, green and blue component on/off and fade between colors. The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip. 3 digital output pins are required to send data down.
The strip is made of flexible PCB material, and comes with a waterproof sheathing.
You can cut this stuff pretty easily with wire cutters, there are cut-lines every 2.5″/6.2cm (2 LEDs each). Solder to the 0.1″ copper pads and you’re good to go. Of course, you can also connect strips together to make them longer, just watch how much current you need! We have a 5V/2A supply that should be able to drive 1 or more meters (depending on use)
They come in 5 meter reels with a 0.1″ molexy connector on the end, and are sold by the meter! If you buy 5m at a time, you’ll get full reels. If you buy less than 5m, you’ll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it.

Please note that this item does not come with an Arduino (you’ll need one to use with the shield), or an SD card. It does come with the RTC battery, however. The kit is un-assembled, You’ll need some basic soldering skills to put it together, but even if you don’t have much experience you can get it done in under 1 hour.
SD card interface works with FAT16 or FAT32 formatted cards. 3.3v level shifter circuitry prevents damage to your SD card
Real time clock (RTC) keeps the time going even when the Arduino is unplugged. The battery backup lasts for years
Included libraries and example code for both SD and RTC mean you can get going quickly
Prototyping area for soldering connectors, circuitry or sensors.
Onboard 3.3v regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run
