What every computer science major should know. Portfolio versus resume Having emerged from engineering and mathematics, computer science programs take a resume-based approach to hiring off their graduates.

What every computer science major should know

A resume says nothing of a programmer's ability. Every computer science major should build a portfolio. IEEE Spectrum: Technology, Engineering, and Science News. Arduino Isn’t Just For Hackers ← Paul M Furley. Arduino turned out to be the perfect match for JF Machines Ltd, a manufacturer of industrial digital printing machines.

Arduino Isn’t Just For Hackers ← Paul M Furley

The open source platform offered them supply security, enormous flexibility and simple PC interfacing, all at an incredible price. Back in 2009 I worked in JF Machines Ltd – the family firm – producing the user operator software for their new digital printing machine, the PicoColour (if you’re imaging a desktop printer, try 1.5 tonnes of precision-engineered printing press…) Picocolour digital inkjet printing machine Like many high-tech manufacturers, JF Machines has historically used both in-house electronics and programmable logic controllers (PLCs). As a quick primer, PLCs are proprietary devices which typically employ a high level language – or even graphical user interface – to describe complex system behaviour.

The PLC is a great sell: simple machine control, little hardware design required and so on, but the flaws soon become apparent. Enter Arduino. The_evolution_of_stencil_technology. T-Pro SG50 5 Gram Micro Servo. THIS IS ONE SUPER MICRO 5G SERVO pole motor and indirect drive give this micro the extreme torque needed for larger aircraft, yet in a size that fits park flyers.

T-Pro SG50 5 Gram Micro Servo

Who buys from us??? Our servos are used by many manufacturers all over the world in helicopters, small to mid-size r/c airplanes, and many schools and institutions (mostly those engineering dudes)! How I Accidentally Kickstarted the Domestic Drone Boom. At last year’s Paris Air Show , some of the hottest aircraft were the autonomous unmanned helicopters—a few of them small enough to carry in one hand—that would allow military buyers to put a camera in the sky anywhere, anytime.

How I Accidentally Kickstarted the Domestic Drone Boom

Manufactured by major defense contractors, and ranging in design from a single-bladed camcopter to four-bladed multicopters, these drones were being sold as the future of warfare at prices in the tens to hundreds of thousands of dollars. In May, at a different trade show, similar aircraft were once again the most buzzed-about items on display. But this wasn’t another exhibition of military hardware; instead, it was the Hobby Expo China in Beijing, where Chinese manufacturers demo their newest and coolest toys.

Companies like Shenzhen-based DJI Innovations are selling drones with the same capability as the military ones, sometimes for less than $1,000. Rascal Micro hands-on (video) Not far from the bustling labs of Northeastern University is the even more bustling hacker space known as Artisan's Asylum.

The roughly 30,000 square foot complex is home to more than 100 makers, tinkerers and artists who building all sorts of crazy contraptions. Dangerous Prototypes 3D project models. We’ve started to build SketchUp 3D models of our projects.

Dangerous Prototypes 3D project models

To automate the process we’re using the EagleUp export/import script. It builds a 3D model of the PCB and arranges models of components onto the board. Sounds simple right? It is pretty easy, but you still have to find or build models for all the parts. Once the parts are built you have to match their 3D origins to the origins of Eagle footprints, and name them the same. We’ve built a small library of components of our parts from various 3D Warehouse models to compliment the ones already available for download at EagleUp. As a feature we will be releasing a 3D model of one of our projects every Monday. Creating Printed Circuit Boards with a INKJET Printer. When I first started looking into how to etch my own printed circuit boards, every Instructable and tutorial I found used a laser printer and ironed on the pattern in some sort of fashion.

Creating Printed Circuit Boards with a INKJET Printer

I don't own a laser printer but I do have an inexpensive inkjet printer. This Instructable will show you how to use your inkjet printer to etch your own printed circuit boards, as well as be able to display a printed component footprint on the top side of the board giving you a professional looking design. For this instructable you will be working with chemicals and power tools. Please wear appropriate protective wear. i.e. goggles, latex gloves, etc. KTechlab IDE: Open source software for microcontroller simulation.
