Automate The Freight: Amazon’s Robotic Packaging Lines

May 29, 2019 by Dan Maloney 50 Comments

In the “Automate the Freight” series, I’ve concentrated on stories that reflect my premise that the killer app for self-driving vehicles will not be private passenger cars, but will more likely be the mundane but necessary task of toting things from place to place. The economics of replacing thousands of salary-drawing and benefit-requiring humans in the logistics chain are greatly favored compared to the profits to be made by providing a convenient and safe commuting experience to individuals. Advances made in automating deliveries will eventually trickle down to the consumer market, but it’ll be the freight carriers that drive innovation.

While I’ve concentrated on self-driving freight vehicles, there are other aspects to automating the supply chain that I’ve touched on in this series, from UAV-delivered blood and medical supplies to the potential for automating the last hundred feet of home delivery with curb-to-door robots. But automation of the other end of the supply chain holds a lot of promise too, both for advancing technology and disrupting the entire logistics field. This time around: automated packaging lines, or how the stuff you buy online gets picked and wrapped for shipping without ever being touched by human hands.

There And Back Again: A Falcon 9 Launch Story

May 28, 2019 by Tom Nardi 23 Comments

It’s true that I’m not known for keeping particularly regular hours, but even I had my doubts about this plan. We’d go to sleep around midnight, wake up at 3 AM, drive up the coast aimlessly, then turn around and attend a full-day event where we’d have to maintain at least some semblance of professionalism. It was a bad idea, terrible even. But there I was at 11:30 PM sitting in a Waffle House with Thomas, the Supplyframe videographer, getting dangerously close to signing off on it.

Officially we were there to cover the Cornell Cup Finals being held at Kennedy Space Center, but as it so happens, our arrival in Florida perfectly coincided with the launch of CRS-17, SpaceX’s latest International Space Station resupply mission. Technically this was not part of our assignment. But really, what choice did we have?

Even if our respective bosses didn’t see it as a wasted opportunity, we had to consider the locals. In the few hours we’d been here, it seemed the launch was all anyone wanted to talk about. Everyone from the airport shuttle driver to the waitress who brought us our hash browns reminded us a rocket would be lifting off soon. If we didn’t go, then come Friday afternoon we’d be the only people in Cape Canaveral who didn’t have a personal account of the event. By all indications, an unforgivable cultural faux pas in central Florida.

Of course, the truth of the matter is that we didn’t actually need any convincing to go on this adventure. We had the supreme good fortune of finding ourselves in the vicinity of Kennedy Space Center a few hours before they were going to send a rocket thundering off into the black, and there was no way we could just sleep through it. No, there was never any choice in the matter. We were going.

Jumbo LEDs Make For A Handy ATtiny Beacon

May 1, 2019 by Tom Nardi 3 Comments

Inspiration can come from anywhere. Sometimes it’s just a matter of seeing an interesting part that you want to fiddle around with badly enough that you end up developing a whole idea, and potentially product, around it. That’s how [Bobricius] found himself creating this very slick little warning beacon, and looking at the end result, we think he made the right decision.

The Kingbright DLC-6SRD “jumbo” LED is actually six individual emitters built into a plastic diffuser. Interfacing with the device is simple enough; each LED has its normal anode and cathode leg, all you need to do is power them up. What [Bobricius] has created is a simple PCB design that the DLC-6SRD can plug right into, complete with a 2032 coin cell holder on the opposite side.

Of course, just lighting up all six elements at the same time wouldn’t be very interesting. [Bobricius] is controlling them individually right off of the digital pins of an ATtiny10 with the help of some Charlieplexing. This makes all kinds of interesting patterns possible, and as demonstrated in the video after the break, the current iteration of the project uses some very simple code to “rotate” the LED as if it was the flasher on an emergency vehicle.

The addition of a few blinking LEDs can make a world of difference in terms of nighttime visibility, so a cheap stick-on module that adds such a distinctive light pattern could be a very important safety device. It could also be useful for UAVs, following the FAA’s new rules which would mandate anti-collision lights for night flying.

Battlebots To The Skies!

May 1, 2019 by Bryan Cockfield 10 Comments

If you’re too young to remember Battlebots on the television, there are two things that you should know. First is that there are plenty of highlights of this epic robot battle royale on YouTube, and the second is that now there’s an even better version with drones instead of robots merely confined to land. It’s called DroneClash 2019, and it looks like it was amazing.

Not only were the robots set up in a box and asked to battle each other, they first had to navigate down a corridor with anti-drone measures. The drones have to make it through and into a battle royale in the final room. If this wasn’t good enough, the event was opened by a prince of the Netherlands and is put on by a university.

This is an annual event to push the state of the art in drone and anti-drone tech, but we’d be happy to see it optioned for a TV show. If it doesn’t, you might be satisfied with a giant human-driven robot competition from a while back, or maybe just head down the rabbit hole of old Battlebots clips.

Zach Archer: Live Coding 500 Watts For ToorCamp

February 28, 2019 by Brian Benchoff 2 Comments

ToorCamp is a five-day open air tech camping event held every two years somewhere around the northwest corner of Washington state. Think of it as something like Burning Man, except you can survive for three hours without water, there aren’t a whole bunch of scenesters and Instagram celebs flying in on private planes, and everyone there can actually build something. Oh, and ToorCamp has delivery drones that will send you creme brulee. These mini creme brulees were probably made with the hot air gun hanging off a soldering station. Don’t worry, you’re getting fresh air that’ll balance out the heavy metal poisoning.

For last year’s ToorCamp, the biggest welcome sign was a 40-foot-long illuminated ToorCamp sign. This was designed, built and coded by Zach Archer, and he was at the 2018 Hackaday Superconference to give us the details on how he made it and how it was coded.

Hackaday Links: February 24, 2019

Back To The Future Part II, released in 1989, told us the far-off future of 2015 would have flying cars, drones working for national newspapers, and self-lacing sneakers. Our best hope for flying cars is Uber, and that’s going to be hilarious when it fails. (Note to Uber: buy KSMO, Santa Monica airport, as an air taxi hub because that’s the most hilarious of all possible realities.) National newspapers — heck, even newspapers — don’t exist anymore. Self-lacing sneakers? Nike’s self-lacing sneakers brick themselves with a firmware update. Don’t worry, it’s only the left shoe.

HackSpace magazine Vol. 16 is out, and there’s a few pages dedicated to Tindie from the person who runs it, our fabulous [Jasmine]. There’s some good tips in here for Tindie sellers — especially shipping — and a good introduction to what Tindie actually is. The three-second elevator pitch of, ‘Etsy but for DIY electronics’ is not in the feature, though.

Is it duct tape or duck tape? That’s a silly question, because it’s ‘duck’ tape, but that’s not important. Gaffer tape is superior. [Ross Lowell], the inventor of gaffer tape, passed away last week at the age of 92.

[Peter Stripol] has a hobby of building ultralights in his basement. Actually, he has a hangar now, so everything’s good. His first two planes flew as Part 103 ultralights, however, there were design problems. [Peter] is using an electric powerplant, with motors and batteries, which is much lighter than a gas-chugging Rotax. However, he was still basing his designs on traditional ultralights. His now third build will be slightly more trimmed down, probably a little bit faster, and might just use 3D-printed control surfaces. Check out the intro to the mk3 airplane here.

[Matthias Wandel], the woodworking Canadian famous for designing the pantorouter, just built a three-legged stool. Sure, that doesn’t sound impressive, but check this out. All the weird mortises were done on the pantorouter, and there are some weird mortises here.

You’re only cool if you got chainz, so here’s some PCB chainz. This was done by [@jeffwurz] with OSHPark PCBs. The design, from as far as we can tell, is simple. It’s just a PCB without a soldermask, and a small cutout in one of the links. Assemble it into a chain, and if you’re clever, solder some resistor leads across the gap to make it a bit more solid.

ASMR, or officially, ‘autonomous sensory meridian response’, is the tingling sensation moving down your back induced by specific auditory (or visual) stimuli. That’s the scientific definition. On the Internet, it’s people breathing into microphones and smacking their lips. Yes, there are videos of this. Thousands of them. There are 11-year-old girls raking in the YouTube money posting ASMR videos. It’s weird and gross, and don’t get me started on slime videos. You’ve also got unboxing videos. The Raspberry Pi foundation found a way to combine ASMR with unboxing videos. I gotta respect the hustle here; ASMR and unboxing videos are some of the most popular content available, and the Pi foundation is not only combining the two, but doing so ironically. It’s exactly the content everyone wants to see, and it’ll bring in people who hate ASMR and unboxing videos. Someone over at the Pi foundation really knows what they’re doing here.
