Hackaday UK Unconference Needs You

August 6, 2017 by Mike Szczys 34 Comments

Hackaday’s first ever conference in the United Kingdom will take place on September 16th. Get your free ticket right now for the Hackaday UK Unconference!

An Unconference is the best way to put your finger on the pulse of what is happening in the hardware world right now. Everyone who attends should be ready to stand and deliver a seven-minute talk on something that excites them right now — this mean you. The easiest thing to do is grab your latest hack off the shelf and talk about that.

Talks may be about a prototype, project, or product currently in progress at your home, work, or university. It could also be an idea, concept, or skill that you’re now exploring. The point is to channel your excitement and pass it on to others in a friendly presentation environment where everyone will cheer as your story unfolds.

Hackaday doesn’t often have the opportunity to organize live events in Europe which is why we’re so happy to partner with DesignSpark, the exclusive sponsor of the Hackaday UK Unconference. DesignSpark is the innovation arm of RS Components and will have some staff on hand at the Unconference. They share our excitement in bringing together the Hackaday community throughout the UK. It is with their support that we are able to book an incredible venue and offer admission at no cost to all attendees. Hackaday events fill to capacity quickly, so get your ticket now before they are gone.

We have already asked a few of our friends in the area if they will be there. Seb Lee-Delisle who wowed us in Belgrade with his laser projection wizardry plans to be there. James Larsson is part of the crew that started the Flashing Light Prize and will be on hand. Phoenix Perry is always on the cutting edge of where people and technology meet and we can’t wait to hear her talk. Mike Harrison of Mike’s Electric Stuff will be around and likely teasing some secret Hackaday hardware he’s spearheading. James Bruton of XRobots (and a Hackaday Prize Judge) is coming, as is Saar Drimer who you may know as the person behind the beautiful hardware art of Boldport. Several Hackaday editors will be there; Elliot Williams, Jenny List, and I will all be on hand. All that’s missing is you.

We’ll flood into the Culture Space at Canada Water on the east side of London starting at 13:00. Tea, coffee, and snacks will be served throughout the afternoon and we’ll provide dinner as well. Anyone who is still standing when we close the doors at 21:00 is invited to join us at the pub afterward (we’ll get the first round).

As always, Hackaday’s success is based on the community of hackers, designers, and engineers that make it up. Please share the link to tickets on your social media and pester your friends to attend. Most importantly, don’t shy away from this speaking opportunity. We want to hear your story and this is the place to tell it. See you in London in just a few short weeks!

UPDATE: Wow, that didn’t take long. The tickets are claimed, but make sure you get on the waitlist. A lot can change in the next five week’s and we’ll be pestering all ticket holders to be there or give their seat up for someone on the waitlist.

Superconference Interview: SpriteTM

August 3, 2017 by Brian Benchoff 1 Comment

SpriteTM, or [Jeroen Domburg], has a bit of a following around these parts. He’s installed Linux on a hard drive the hard way. He can play Snake on his keyboard. He’s cared for several generations of Tamagotchis. In short, there are very few people who have both the technical ability and sense of humor to pull off what [Sprite] does.

At last year’s Supercon, we pulled Sprite aside to talk about his work and his latest hack, the tiniest Game Boy ever. He talked about his Supercon keynote, and how to hack the crypto challenge in last year’s Superconference badge in an hour without solving any of the puzzles. Now, we’re happy to present that interview today, available below.

While we very much doubt many people could — or would — take four conference badges and rick roll the entire Superconference for the badge hacking session, we’re still looking for eager and capable presenters. The Call for Proposals is now open for the 2017 Hackaday Superconference. If you have a story of hardware heroics, creativity in CPLDs, a passion for prototyping, or an ambition for technological art, we want you to share your story. Even if you don’t, that’s fine, too: tickets are still available for the Superconference in Pasadena, California on November 11th and 12th.

Eclipse 2017: Where Will You Be When The Sun Goes Away?

August 2, 2017 by Dan Maloney 62 Comments

In less than a month, on August 21, 2017, the Moon will cast its shadow upon the Earth, a relative pinprick at only 60 miles across. The shadow will begin in the Pacific Ocean off North America, make landfall south of Portland, Oregon, and rake diagonally across the United States. Charging southeastward at about 2000 miles an hour, the path of totality will touch 12 states before racing off into the Atlantic Ocean around Charleston, South Carolina.

Those are the dry facts of the eclipse, the wheres and the whens of an event that hasn’t been visible to a majority of the US population in 47 years. But beyond the science and the natural wonder of the celestial alignment lies a simple question: Where will you be when the sun goes away?

An Eclipse from a Volcano

Bullseye! The center of totality passes right through North Menan Butte in Rexburg, ID.

For me, the answer is simple: I’ll be smack dab in the middle of totality on top of an extinct volcano in eastern Idaho. To see an eclipse is pretty cool; to watch the mechanics of the heavens work above you while standing in a unique geological feature will be far cooler.

It will take me eight hours to drive to Menan Buttes with my family from our home in the Panhandle; Idaho is an enormous state. We’ll be camping on private land outside the southern butte, probably in pretty rustic conditions and without a lot of rough camping experience. OK, none. But I don’t care because I want to see totality, and the 92% totality we’d see if we stayed home just won’t cut it.

While most people will likely have their eyes cast heavenward with their cheap cardboard and plastic eclipse glasses or shade 14 welding lens when the big moment arrives, my eyes will be locked on the ground to the west of our vantage point. Menan Butte stands about 500′ above the flat, featureless Snake River plain, and I intend to watch the moon’s shadow racing across the planet toward us. That’s the draw for me, and I hope I get to see it.

That’s not to say I won’t look skyward once the shadow is upon us, gazing in wide wonder at the incandescent dance of our sun’s atmosphere against the suddenly dark sky. I’ll bask in the unnatural twilight, listen to the gasps and cheers of my fellow watchers, and feel the sudden temperature drop, which should be quite marked in the east Idaho drylands. We’ll have about two minutes of totality before the shadow races east toward the vast majority of the US population, and I plan to enjoy every second of it.

Hackaday Eclipse Meetups

Aside from just watching the eclipse, there’s plenty else to do. Hackaday.io members across the country are hosting Hackaday Eclipse Meetups, where like minded folks can mix and mingle before the eclipse. If you know where you’ll be to watch the eclipse — like an extinct volcano, for instance — and you don’t mind sharing the experience with some of your fellow enthusiasts, be sure to post a meetup on the Eclipse Meetups page. Make your event page and we’ll send you some eclipse glasses with the Jolly Wrencher on the side of them for you and your guests.

Have you started thinking of what you’re going to bring with you to the viewing? There are a lot of eclipse projects, from pinhole cameras to watch the eclipse safely, to the Ham operators who will be taking advantage of localized ionospheric changes to make long-distance contacts. Those of us with telescopes might want to build a low-cost solar filter. Someone will likely be trying to prove General Relativity somewhere along the path of totality, and we’d love to see the rig for that. And there will no doubt be petabytes of photographs and videos taken with everything ranging from smartphones to professional cinematic cameras. We’d love to hear what you’re planning and see your setups. And even if you’ve got something cool that’s not eclipse related, bring it along. It’s always a good time to talk shop for hackers.

This Weekend: Vintage Computer Festival West

August 1, 2017 by Mike Szczys 3 Comments

Next weekend is the Vintage Computer Festival West, held at the Computer History Museum. Hackaday is once again proud to sponsor this event that brings together the people and hardware that drove the information revolution. [Bil Herd] and [Joshua Vasquez] will be on hand representing the Hackaday Crew.

This year’s talks show an impressive lineup of people. [Bil Herd] will be on stage with a collection of other engineers who secured Commodore’s place in history. The Computer History Museum has a very active restoration program for original computer hardware. Friend of Hackaday, [Ken Shirriff], has been working on a restoration of the Xerox Alto and is on the panel giving a talk about the process. And just to cherry-pick one more highlight, there’s a talk on system debugging before you even turn the thing on — a topic that can save you from having a very bad day with very ancient hardware.

A great part of VCF is that the exhibits are often either hands-on or demonstrations so you can actually play around with hardware which most people have never even seen in person. Add to that the collection at the Computer History Museum plus some extra exhibits they have planned for the event and you’re likely to run out of time before you make your way through everything.

Since we’ve mentioned the Computer History Museum, we also have some upcoming news. A bit later this month, Hackaday Contributor-at-Large [Voja Antonic] has been invited to visit the museum, record his oral history, and deliver to their collection an original Galaksija computer — wildly successful first as a kit and then as a manufactured computer which he built in Yugoslavia 1983. Congratualtions [Voja]!

Look What People Brought To Breakfast At DEF CON

August 1, 2017 by Mike Szczys 14 Comments

Sunday was our Breakfast at Hackaday meetup and a swarm of folks showed up, take a look at the hardware they brought with them! Vegas can be a tough place to set up a meetup — especially if you don’t want to rent a room. We filtered into a Starbucks across the street from Caesar’s and ended up packing the high-top table areas. It turns out you get a really funny look from the baristas when you go through the coffee line and ask for four dozen pastries and a few buckets of coffee.

About 30 minutes before official start

Too busy talking hardware to look

The size of the space made it hard to get a picture of the entire crowd. I did manage to get a posed photo with the people who showed up about a half hour early. Once it filled up all I got for crowd shots were people with their back to me and heads down comparing hardware projects — that might actually be more appropriate for DEF CON where people generally don’t want to be photographed (case in point our bandanna wearing friend).

Swag, pastries, and RF hacking

print your Storm Trooper helmet

custom headgear

There was a ton of different hardware on hand. If you look at a picture of the swag and pastries tables, look closely at the high-top behind that. There were a couple of people hacking on RTL-SDRs before we arrive (which means they were at least 45 minutes early).

I’m a fan of wearing your hardware projects at events and this year was really great for that. First, a Captain Phasma helmet from The Force Awakens. It’s 3D printed in ABS, using an acetone/ABS slurry to glue (actually to weld) the parts before sanding and painting to finish the job.

Dragonfly badge (proper name: Sympetrum)

AND!XOR badges within BT range

Most of the hacks on hand were unofficial hardware badges built specifically for DEF CON. I was at the Badge Build’s meetup and have a megapost on everything I saw there coming out a bit later. But here we get a look at the dragonfly badge which [Kerry] brought along with him as well as the rectangular PCB that was the prototype. The AND!XOR crew was in the house and I decided to bug [Hyr0n] about the password hashes I was trying to crack from their badge’s firmware. He pulled up the app and it wasn’t surprising to see so many of the Bender on a bender badges in the area. Their botnet was a huge hit this year!

At some point, I was handed this book-like box which had been laser cut and etched out of plywood. It’s a beautiful piece and I had no idea what I would find inside. Turns out it’s a complete quadcopter-badge fun kit. I must have been so enthralled with the electronics when we covered this badge a few weeks back that I completely missed the beautiful box they built for it.

Inside the box, you’ll find two versions of the badge (one that flies, the other that blinks and has a red PCB handkerchief), a separate PCB that is the controller, and a goodie bag with extra batteries and charging hardware. We didn’t fire this up at the meetup, but we’ll have it at the Hackaday Superconference for you to play with. It was really great to get a group picture with so many of the people who worked on making this badge happen.

There was one high-top over in the corner that had been mobbed with people all morning and I only got a look at it when the crowd started to clear out around noon. [Brian McEvoy] built a custom controller for OpenSCAD and did a great job of bringing along a demo. A tablet is running the software, with the controller connected via USB. There are 3 knobs on the right that allow you to adjust height, width, and depth. The fourth knob is for adjusting precision. That precision is displayed in a very clever way. You can see the LED strip with has a red dot on the right (the decimal point) and three colored pixels to the left of it. These are the tens, hundreds, and thousands, but just turn the crank until the red dot is at the other end of the strip and you’ll be setting precision to tenths, hundreths, etc. [Brian] even added a button you can hold down to 10x the precision without making a permanent adjustment. The project is driven by a Teensy LC board.

Is wonderful to see the Hackaday Community turn out for a meetup like this even though so much other stuff is going on at DEF CON. Thank you to all of you for coming to say hi, share your stories, and show off your handy work!

“Borrow” Payment Cards With NFC Proxy Hardware

July 31, 2017 by Mike Szczys 31 Comments

Contactless payments are growing in popularity. Often the term will bring to mind the ability to pay by holding your phone over a reader, but the system can also use NFC tags embedded in credit cards, ID card, passports, and the like. NFC is a reasonably secure method of validating payments as it employs encryption and the functional distance between client and reader is in the tens of centimeters, and often much less. [Haoqi Shan] and the Unicorn team have reduced the security of the distance component by using a hardware proxy to relay NFC interactions over longer distances.

The talk, give on Sunday at DEF CON, outlined some incredibly simple hardware: an NFC antenna connected to a PN7462AU, an NRF24L01 wireless transceiver, and some power regulation. The exploit works by using a pair of these hardware modules. A master interfaces with the NFC reader, and a slave reads the card. The scenario goes something like this: a victim NFC card is placed near the slave hardware. The master hardware is placed over a payment kiosk as if making a normal payment. As the payment kiosk reader begins the process to read an NFC card, all of the communications between it and the actual card are forwarded over the 24L01 wireless connection.

The demo video during the talk showed a fast-food purchase made on the Apple Pay network while the card was still at a table out in the dining area (resting on the slave hardware module). The card used was a QuickPass contactless payment card from China UnionPay. According to a 2016 press release from the company, over two billion of these cards had been issued at the time. With that kind of adoption rate there is a huge incentive to find and patch any vulnerabilities in the system.

The hardware components in this build aren’t really anything special. We’ve seen these Nordic wireless modules used in numerous projects over they years, and the NXP chip is just NFC build around an ARM core. The leaps that tie this together are the speed-ups to make it work. NFC has tight timing and a delay between the master and slave would invalidate the handshake and subsequent interactions. The Unicorn team found some speedups by ensuring the chip was waking from suspend mode (150 µS) and not a deeper sleep. Furthermore, [Haoqi] mentioned they are only transmitting “I/S/R Block Data” and not the entirety of the interaction to save on time transmitting over the 24L01 wireless link. He didn’t expand on that so if you have details about what those blocks actually consist of please let us know in the comments below.

To the card reader, the emulated payment card is valid and the payment goes through. But one caveat to the system is that [Haoqi] was unable to alter the UID of the emulator — it doesn’t spoof the UID of the payment card being exploited. Current readers don’t check the UID and this could be one possible defense against this exploit. But to be honest, since you need close physical proximity of the master to the reader and the slave to the payment card simultaneously, we don’t see mayhem in the future. It’s more likely that we’ll see hacker cred when someone builds a long-range link that lets you leave your NFC cards at home and take one emulator with you for wireless door access or contactless payments in a single device. If you want to get working on this, check out the talk slides for program flow and some sourcecode hints.

Looking Forward To SHA2017

July 30, 2017 by Jenny List 17 Comments

We’re at the start of August, which can only mean one thing. Europe’s hackers and makers are about to converge in a field somewhere for a long weekend of sitting around drinking beer and Club-Mate, eating unhealthy street food, being assaulted by some of the most underground chiptune electronic dance music on the planet, sharing the fruits of their labours with their peers, and gazing lovingly upon other people’s hacks. This year it’s the turn of the Netherlands, for over the first full weekend in August that country will host the SHA2017 outdoor hacker camp in a scouting camp on the polders. It promises to be quite an event, with just short of 4000 attendees spread over several fields, arenas, and social areas, and we’re going to be there. Tent and power lead with Schuko plug sorted, massive pile of stickers secured, DECT phone charged, emergency supplies of PG Tips packed.

There is so much to take in at these events that it can sometimes be difficult to catch everything. One can do the rounds as diligently as possible and still miss some of the cool stuff, so this is where you come in. Are you going to SHA? Are you bringing anything you consider cool to the event? Tell us about it in the comments, we’d love to hear about it as would we’re sure the rest of our readers.

Meanwhile, if you think you’ve missed the boat, don’t panic! At the time of writing, there are about 180 tickets still unsold, but they’ll be going fast! Head over to the SHA2017 tickets site to get yours.

(The stripey header, in case you were wondering, is SHA2017’s branding using as you might have guessed, the SHA algorithm to generate HTML colours. What you see are the colours for “Hackaday”.)
