LayerOne Demoscene Demoboard Party

The LayerOne conference is over, and that means this last weekend saw one of the biggest demoscene parties in the USA. Who won? A European team. We should have seen this coming.

There were two categories for the LayerOne demo compo, the first using only the LayerOne Demoscene Board. It’s a board with a PIC24F microcontroller, VGA out, and a 1/8″ mono audio out. That’s it; everything that comes out of this board is hand coded on the PIC. A few months ago, [JKing] wrote a demo to demonstrate what this demoboard can do. According to him, it’s the only reason Hackaday sold a single Demoboard in the Hackaday store:

First place for the Demoscene Board competition went to a remote entry – a team called COINE. The video and initial reactions of everyone in the room:

No one in the idea had any idea how this was possible. The hardware should not be able to do that. The resolution and number of colors are too high. It was, by far, the most impressive demo at LayerOne. That doesn’t mean the other submissions to the Demoscene board competition were overlooked. [jamisnemo]’s entry was well received, even though he ran out of time writing it:

The second category for the LayerOne demo competition was the ‘Secret’ Board. There were only 10 or 12 of these boards ever made , but there were still some impressive entries. The board itself is built around an ATMega88 – 8k of Flash, 1K of RAM, and 512 Bytes of EEPROM. If using an ATMega88 as a demo platform sounds familiar, you’d be right. [lft] built the Craft demo way back in 2008 around this chip. The Secret Board is designed to run this demo, and serve as a platform for a demo that implemented a framebuffer on the ‘Mega88:

In all, an excellent competition. It was well received by all attendees, and next year’s compo is sure to be even bigger. If anyone has any idea on how the big European capture these demos to video, please leave a note in the comments. No one at LayerOne could figure it out.

LayerOne Hardware Hacking Village

Go to DEFCON and you’ll stand in line for five hours to get a fancy electronic badge you’ll be showing to your grandchildren some day. Yes, at DEFCON, you buy your hacker cred. LayerOne is not so kind to the technically inept. At LayerOne, you are given a PCB, bag of parts, and are told to earn your hacker cred by soldering tiny QFP and SOT-23 chips by hand. The Hardware Hacking Village at LayerOne was packed with people eagerly assembling their badge, or badges depending on how cool they are.

The badges are designed by [charlie x] of null space labs, one of the many local hackerspaces around the area. The design and construction of these badges were documented on the LayerOne Badge project on, and they’re probably best con badges we’ve ever seen.

There are two badges being distributed around LayerOne. The first is an extremely blinkey badge with a Cypress PSoC4 controlling 22 individually addressable RGB LEDs. Most conference attendees received a bare PCB and a bag of parts – the PCB will get you in the door, but if you want your nerd cred, you’ll have to assemble your own badge.

There are still a few interesting features for this badge, including an ESP8266 module that will listen to UDP packets and drive the LEDs. Yes, a random person on the same WiFi AP can control the LEDs of the entire conference event. The badges can also be chained together with just three wires, but so far no one has done this.

The Speaker and Staff badge, based on a VoCore

The second badge – for speakers and staff – is exceptionally more powerful. It’s a Linux box on a badge with two Ethernet connectors running OpenWRT. For a con badge, it’s incredibly powerful, but this isn’t the most computationally complex badge that has ever been at a LayerOne conference. For last year’s badge, [charlie] put together a badge with an FPGA, SAM7 microcontroller, SD card, and OLED display. They were mining Bitcons on these badges.

The Hardware Hacking Village was loaded up with a dozen or so Metcal soldering irons, binocular microscopes, and enough solder, wick, and flux to allow everyone to solder their badge together. Everyone who attempted it actually completed their badge, and stories of badge hacking competitions at other cons were filled with tales of people sprinkling components on random solder pads. Imagine: a conference where people are technically adept. Amazing.

Pictures that Defeat Key Locks

We’re at LayerOne this weekend and one of the talks we were excited about didn’t disappoint. [Jos Weyers] presented Showing Keys in Public — What Could Possibly Go Wrong? The premise is that pictures of keys, in most cases, are as good as the keys themselves. And that pictures of keys keep getting published.

[Jos] spoke a bit about new services that offer things like 3D scanning and storage of your key for printing when you get locked out, or apps that ask you to take a picture of your key and they’ll mail you a duplicate. Obviously this isn’t the best of ideas; you’re giving away your passwords. And finding a locksmith is easier than findind a 3D printer. But it’s the media gaffs with important keys that intrigues us.

We’ve already seen the proof of concept for taking covert images to perfectly duplicate a key. But these examples are not so covert. One example is a police officer carrying around handcuff keys on a belt clip. Pose for a picture and that key design is now available to all. But news stories about compromised keys are the biggest offenders.

subway-keysA master key for the NYC Subway was compromised and available for sale. The news coverage not only shows a picture at the top of the story of a man holding up the key straight on, but this image of it on a subway map which can be used to determine scale. This key, which is still published openly on the news story linked above, opens 468 doors to the subway system and these are more than just the ones that get you onto the platform for free. We were unable to determine if these locks have been changed, but the sheer number of them has us thinking that it’s unlikely.

firemans-keysWorse, was the availability of fire-department master keys which open lock boxes outside of every building. (Correction: these are fire department keys but not the actual lock-box keys) A locksmith used to cut the original keys went out of business and sold off all their stock. These keys were being sold for $150, which is bad enough. But the news coverage showed each key on a white background, straight on, with annotations of where each type of key will work.

Other examples include video news stories about credit card skimmers installed in gas pumps — that coverage showed the key used to open the pump housing. There was also an example of speed camera control cabinet keys being shown by a reporter.

key-photo-duplication-layerone[Jos’] example of doing the right thing is to use a “prop” key for news stories. Here he is posing with a key after the talk. Unfortunately this is my own house key, but I’m the one taking pictures and I have blurred the teeth for my own security. However, I was shocked during image editing at the quality of the outline in the image — taken at 6000×4000 with no intent to make something that would serve as a source for a copy. It still came out remarkably clear.

Some locks are stronger than others, but they’re all meaningless if we’re giving away the keys.

See You at LayerOne this Weekend

LayerOne, the first level of security. [Brian Benchoff] and I are excited to take part in our first LayerOne conference this Saturday and Sunday in Monrovia California.

Anyone in the Los Angeles area this weekend needs to get out of whatever they have planned and try out this conference that has a soul. Get the idea of a mega-con out of your head and envision a concord of highly skilled and fascinating hackers gathering to talk all things computer security. Speakers will cover topics like researching 0day exploits, copying keys from pictures taken in public, ddos attacks, social engineering, and more.

It’s not just talks, there is a ton of hands-on at LayerOne as well. I plan to finally try my hand at lock picking. Yep, I’ve covered it multiple times and we’ve even had a session led by [Datagram] at the Hackaday 10th Anniversary but I’ve never found time to give it a roll. Of course electronics are my game and [Brian] and I will both be spending a fair amount of time in the hardware hacking village. We’ll have a bunch of dev boards along with us if you want to try out an architecture with which you’re unfamiliar. This year’s LayerOne badges are sponsored by Supplyframe; we’ll have something in store for the best badge hacks we see during the weekend.

See you there!

Seeing everything at Bay Area Maker Faire means a lot of time on your feet. By the end of the day the Hackaday Crew is ready to take a load off and toss back a tasty beverage. We invite you to join us on Saturday, May 16th starting at 7pm. All the cool kids will be there so please RSVP now.

It’s not compulsory, but a lot of people bring hardware they’ve been working on to show off at this meetup and you should too!

layerone-logoMay 23 & 24 LayerOne Conference

Every year our friends from NullSpace Labs organize the LayerOne Conference in Los Angeles. This is LA’s premier hardware security conference. This year Supplyframe is sponsoring the badges and Hackaday will be camped out at the Hackaday Hardware Villiage.

[Brian Benchoff] and [Mike Szczys] will be hacking their own badges while looking for awesome hacks other people are pulling off. We’ll bring plenty of swag and want to get everyone there to try at least some level of badge hack.

Revive The Demoscene with a LayerOne Demoscene Board

Demos, the demoscene, and all the other offshoots of computer arts had their beginning as intros for cracked Apple II, Speccy, and Commodore 64 games. Give it a few years, and these simple splash screens would evolve into a technological audio-visual experience. This is the birth of the demoscene, where groups of programmers would compete to create the best demonstration of computer graphics and audio.

For one reason or another, this demoscene was mostly confined to Europe; even today, 30 years after the Commodore 64, the North American demoscene is just a fraction of the size of the European scene. A very cool guy named [Arko] would like to change that, and to that end he built the LayerOne Demoscene Board.

If there is a problem with the modern demo scene, it’s that the hardware that’s usually used – C64s, Ataris, Spectrums, and Amigas – are old, somewhat rare, and dying. There’s also the fact that artists have been working on these old machines for decades now, and every single ounce of processing power and software trickery has been squeezed out of these CPUs. [Arko]’s board is a ground-up redesign of what a board that plays demos should be. There’s only one chip on the board – a PIC24F with three graphics acceleration units, color lookup tables, and the ability to output 16-bit VGA video up to 640×480 with 8-bit audio.

The first official competition with the LayerOne Demoscene Board will be at the 2015 LayerOne conference in Monrovia, CA on May 23. There are a few categories, including 4k and 64k JavaScript, Raspberry Pi, the LayerOne board, and a ‘Wild’ category. If you want to take a processor out of a toaster and make a demo, this is the category you’ll be entering. Of course Hackaday will be there, and we’ll be recording all the demos.

Below are a few examples of what the LayerOne Demoscene board can do, and you can also see a talk [Arko] gave at the Hackaday 10th anniversary party here. You can buy the Layerone Demoscene Board on the Hackaday Store

2013 LayerOne badge hacking contest winner


[Dynotronix] wrote in to share the news that he won the 2013 LayerOne badge hacking contest. In addition to the good news he included a description of his badge hack.

We got a good look at the hardware included on the badge several days ago. You may remember that it’s outfitted with footprints for 48 LEDs around the perimeter which are driven by two ICs. Looking at the image above it’s hard to miss the fact that [Dyno] didn’t populate any of that. He went right for the power of the XMEGA processor to analyze and generate signals.

But what specifically can you do with the signal this thing generates? Turns out a rather simple circuit can make it into a transmitter. [Dyno] concedes that it’s a remarkably finicky setup, but just a few components on a scrap of copper clad turned this into an FM transmitter. Check out the video where you can hear the sweeping alarm-type sounds pushed to an FM radio via his voltage controlled oscillator circuit which has a range of about fifteen feet.
