Here’s The Reason The FAA’s Drone Registration System Doesn’t Make Sense

Last week, the US Department of Transportation and FAA released their rules governing drones, model aircraft, unmanned aerial systems, and quadcopters – a rose by any other name will be regulated as such. Now that the online registration system is up and running.

The requirements for registering yourself under the FAA’s UAS registration system are simple: if you fly a model aircraft, drone, control line model, or unmanned aerial system weighing more than 250g (0.55 lb), you are compelled under threat of civil and criminal penalties to register.

This is, by far, one of the simplest rules ever promulgated by the FAA, and looking at the full text shows how complicated this rule could have been. Representatives from the Academy of Model Aircraft, the Air Line Pilots Association, the Consumer Electronics Association weighed in on what types of aircraft should be registered, how they should be registered, and even how registration should be displayed.

Considerable attention was given to the weight limit; bird strikes are an issue in aviation, and unlike drones, bird strikes have actually brought down airliners. The FAA’s own wildlife strike report says, “species with body masses < 1 kilogram (2.2 lbs) are excluded from database,”. The Academy of Model Aircraft pushed to have the minimum weight requiring registration at two pounds, citing their Park Flyer program to define what a ‘toy’ is.

Rules considering the payload carrying ability of an unmanned aerial system were considered, the inherent difference between fixed wing and rotors or quadcopters was considered, and even the ability to drop toy bombs was used in the decision-making process that would eventually put all remotely piloted craft weighing over 250g under the FAA’s jurisdiction. We must at least give the FAA credit for doing what they said they would do: regulate drones in a way that anyone standing in line at a toy store could understand. While the FAA may have crafted one of the simplest rules in the history of the administration, this rule might not actually be legal.

Giving The C64 A WiFi Modem

If there’s any indication of the Commodore 64’s longevity, it’s the number of peripherals and add-ons that are still being designed and built. Right now, you can add an SD card to a C64, a technology that was introduced sixteen years after the release of the Commodore 64. Thanks to [Leif Bloomquist], you can also add WiFi to the most cherished of the home computers.

[Leif]’s WiFi modem for the C64 is made of two major components. The first is a Microview OLED display that allows the user to add SSIDs, passwords, and configure the network over USB. The second large module is the a Roving Networks ‘WiFly’ adapter. It’s a WiFi adapter that uses the familiar Xbee pinout, making this not just a WiFi adapter for the C64, but an adapter for just about every wireless networking protocol out there.

[Leif] introduced this WiFi modem for the C64 at the World of Commodore earlier this month in Toronto. There, it garnered a lot of attention from the Commodore aficionados and one was able to do a video review of the hardware. You can check out [Alterus] loading up a BBS over Wifi in the video below.

Reverse Engineering The ARM ALU

[Dave] wanted to learn more about the ARM architecture, so he started with an image of the ARMV1 die. If you’ve had some experience looking at CPU die, you can make some pretty good guesses at what parts of the chip have certain functions. [Dave], however, went further. He reverse engineered the entire ALU–about 2,200 transistors worth.

RGB LED Ceiling Display

yP8PoVDisco Floor’s are passé. [dennis1a4] turned them upside down and built an awesome RGB LED ceiling display using some simple hardware and a lot of elbow grease. His main room ceiling was exactly 32 ft x 20 ft and using 2 sq. ft tiles, he figured he could make a nice grid using 160 WS2812B RGB LEDs. A Teensy mounted in the ceiling does all the heavy lifting, with two serial Bluetooth modules connected to it. These get connected to two Bluetooth enabled NES game controllers. Each of the NES controller is stuffed with an Arduino Pro Mini, a Bluetooth module, Li-Ion battery and a USB charge controller.

Bluetooth is in non-secure mode, allowing him to connect to the Teensy, and control the LEDs, from other devices besides the NES controllers. The Teensy is mounted at the centre of the ceiling to ensure a good Bluetooth link. Programming required a lot of thought and time but he did manage to include animations as well as popular games such as Snake and Tetris.

LED_Ceiling_deadbugThe hard part was wiring up all of the 160 LED pixels. Instead of mounting the 5050 SMD LED’s on PCBs, [dennis1a4] wired them all up “dead bug” style. Each pixel has one LED, a 100nF decoupling capacitor, and 91 ohm resistors in series with the Data In and Data Out pins – these apparently help prevent ‘ringing’ on the data bus. Check the video for his radical soldering method. Each SMD LED was clamped in a machine shop vice, and the other three parts with their leads preformed were soldered directly to the LED pins.

The other tedious task was planning and laying out the wiring harness. Sets of 10 LEDs were first wired up on the shop bench. He then tacked them up to the ceiling and soldered them to the 14 gauge main harness. The final part was to put up the suspended ceiling and close the 2 sq. ft. grids with opaque plastic.

[dennis1a4]  did some trials to figure out the right distance between each LED and the panel to make sure they were illuminated fully without a lot of light bleeding in to adjacent panels. This allowed him to get away without using baffles between the tiles.

Check out the video to see a cool time-lapse of the whole build.

Madeline Gannon The Robot Tamer!

Let’s be honest. Who doesn’t want an industrial six-axis robot arm in their garage to do their bidding? Introducing [Madeline Gannon], the Robot Tamer!

The only tricky part is… if you received an industrial six-axis robot arm, would you be able to control it to do your bidding (easily)? Having taken robotics courses myself in college, and worked with ABB robots like this one, I can tell you, it’s not exactly plug-and-play. Yeah, there’s the teach pendant and you can pretty quickly teach the robot to do a repetitive task well, but unless you’re setting up your own mini manufacturing line — what’s the point? You’re going to want to inject some CNC code or something and have it carve you a sculpture! Or pour you a mixed drink I guess…

Maybe [Madeline] has the answer. Working as an artist in residence at Pier 9, she’s created wearable markers and a motion capture system that allows a giant ABB robot to see, and respond to your movements in a shared space.

Hackaday Links: December 20, 2015

If you don’t have a Raspberry Pi Zero right now, you’re not getting one for Christmas. Who would have thought a $5 Linux computer would have been popular, huh? If you’re looking for a new microcontroller platform you can actually buy, the Arduino / Genuino 101 is available in stores. This was released a few months ago, but it still looks pretty cool: DSP, BTLE, and a six-axis sensor.

If you don’t know [David], the Swede, you should. He’s the guy that launched a glider from a high altitude balloon and is one of the biggest advocates of tricopters. Now he bought an airplane wing for his front yard. It was an old Swedish air force transport aircraft being broken up for scrap. Simply awesome.

Chocolate chips. Now that the most obvious pun is out of the way, here’s how you make DIP8 cookie cutters.

[Barb] is over at the Crash Space hackerspace in LA, and she has a YouTube channel that goes over all her creations. This week, it’s a layered wood pendant constructed out of many layers of veneer. Take note of the 3M 77 spray glue used for the lamination and the super glue used as a clear, hard finish.

Star Wars was released and we have a few people digging through the repertoire to see what [John Williams] lifted for the new movie. Here’s musical Tesla coils playing the theme for the Force.

Flickr gives you a full gigabyte of storage, but only if you upload JPEGs, GIFs, and PNGs. That doesn’t prevent you from using Flickr as your own cloud storage.

We know two things about [Hans Fouche]: he lives in South Africa and he has a gigantic 3D printer. His latest creation is an acoustic guitar. It may not sound great, but that’s the quality of the recording. It may not play great, but he can fix that with some acetone vapor. It would be very interesting to see 3D printing used in a more traditional lutherie context; this printer could easily print molds and possibly even something to bend plywood tops.

Starting in 1990, [deater] would make a yearly Christmas-themed demo on his DOS box. You can really see the progression of technology starting with ANSI art trees written in BASIC, to an EGA graphical demo written with QBASIC to the last demo in 96 made with VGA, and SoundBlaster effects written in Turbo Pascal and asm.

3D Printed Hydraulics

[Robert MacCurdy] at MIT wants to change how people think about hydraulics. Using fluid can be very useful in systems like robots, but it is often the case that the tubing that carries hydraulic fluid is not an integrated part of the overall design. [MacCurdy] and his colleagues have modified a 3D printer to allow it directly include hydraulic components as it prints.

The idea is simple. The team started with a printer that uses a liquid ink that is UV cured to produce solid layers. The printer has the ability to use multiple liquids, and [MacCurdy] uses hydraulic fluid (that does not UV cure) as one of the print materials. Just as you can use a 3D printer to build structures within other structures, printing the hydraulics allows for complex closed systems that use the UV-cured resin as mechanical parts that can transfer pressure to and from the hydraulic system.
