Planespotter Spots Planes, Tracks Destinations

July 17, 2016 by 11 Comments

Ever looked up in the sky and wondered where all of those planes above you were going? [squix] no longer has to, thanks to his ESP8266-based Planespotter.

He built this nifty device to grab the details of the flights he sees taking off from Zurich airport. It’s a neat build, running on an ESP8266 that receives ADS-B data from ADS-B Exchange. This service allows you to query the ADS-B data with a specific location.

[squix]’s plane tracker sends a query to ADS-B exchange for flights in his location and below a certain height (so he sees ones that are just taking off), then displays the received information on the OLED screen. He says a display-only version will run you around $20, while the full version that also receives and shares data with the ADS-B Exchange will cost you about $50. That’s a lot cheaper than a plane ticket…

It’s Time For Direct Metal 3D-Printing

May 19, 2016 by 75 Comments

It’s tough times for 3D-printing. Stratasys got burned on Makerbot, trustful backers got burned on the Peachy Printer meltdown, I burned my finger on a brand new hotend just yesterday, and that’s only the more recent events. In recent years more than a few startups embarked on the challenge of developing a piece of 3D printing technology that would make a difference. More colors, more materials, more reliable, bigger, faster, cheaper, easier to use. There was even a metal 3D printing startup, MatterFab, which pulled off a functional prototype of a low-cost metal-powder-laser-melting 3D printer, securing $13M in funding, and disappearing silently, poof.

This is just the children’s corner of the mall, and the grown-ups have really just begun pulling out their titanium credit cards. General Electric is on track to introduce 3D printed, FAA-approved fuel nozzles into its aircraft jet engines, Airbus is heading for 3D-printed, lightweight components and interior, and SpaceX has already sent rockets with 3D printed Main Oxidizer Valves (MOV) into orbit, aiming to make the SuperDraco the first fully 3D printed rocket engine. Direct metal 3D printing is transitioning from the experimental research phase to production, and it’s interesting to see how and why large industries, well, disrupt themselves.

WingBoard: Wakeboarding Behind An Airplane

January 10, 2016 by 36 Comments

[Aaron Wypyszynski] or [Wyp] for short had a dream as a youngster about jumping out of a plane and “carving through the sky” (paraphrasing the video embedded after the break), so when he grew up [Wyp] went ahead and pursued that dream.

What that boyhood dream produced is [Wyp] offering to pull you through the sky on what looks like a proper model of a blunt nosed paper airplane glider. Seems to be a bit like wakeboarding for skydivers, cause that needed to be a thing.

Tracking Nearly Every Aircraft With A Raspberry Pi

July 18, 2015 by 19 Comments

FlightAware is the premier site for live, real-time tracking of aircraft around the world, and for the last year or so, Raspberry Pi owners have been contributing to the FlightAware network by detecting aircraft flying overhead and sending that data to the FlightAware servers.

Until now, these volunteers have used Raspis and software defined radio modules to listen in on ADS-B messages transmitted from aircraft. With FlightAware’s new update to PiAware, their Raspberry Pi flight tracking software, Mode S transponders can also be detected and added to the FlightAware network.

Last year, FlightAware announced anyone with a Raspberry Pi, a software defined radio module, and an Internet connection would earn a free FlightAware enterprise account for listening to ADS-B transmitters flying overhead and sending that information to the FlightAware servers. ADS-B is a relatively new requirement for aviators that transmits the plane’s identification, GPS coordinates, altitude, and speed to controllers and anyone else who would like to know who’s flying overhead.

Mode S transponders, on the other hand, are older technology that simply transmits the call sign of an aircraft. There’s no GPS information or altitude information transmitted, but through some clever multilateration in the new PiAware release these transponders and planes can now be tracked.

To get the location of these transponders, at least three other PiAware boxes must receive a signal from a Mode S transponder. These signals, along with a timestamp of when they were received are then sent to the FlightAware servers where the location of a transponder can be determined.

The end result of this update is that FlightAware can now track twice as many aircraft around the world, all with a simple software update. It’s one of the most successful applications of crowdsourced software defined radio modules, and if you’d like to get in on the action, the FlightAware team put together a bulk order of ADS-B antennas.
