[Ryan] a.k.a. [1o57] comes from an age before anyone could ask a question, pull out their smartphone, and instantly receive an answer from the great Google mind. He thinks there’s something we have lost with our new portable cybernetic brains – the opportunity to ask a question, think about it, review what we already know, and reason out a solution. There’s a lot to be said about solving a problem all by yourself, and there’s nothing to compare to the ‘ah-ha’ moment that comes with it.
[1o57] started his Mystery Challenges at DEFCON purely by accident; he had won the TCP/IP embedded device competition one year, and the next year was looking to claim his title again. The head of the TCP/IP embedded competition had resigned from his role, and through a few emails, [1o57] took on the role himself. There was a miscommunication, though, and [1o57] was scheduled to run the TCP/IP drinking competition. This eventually morphed into a not-totally-official ‘Mystery Challenge’ that caught fire in email threads and IRC channels. Everyone wanted to beat the mystery challenge, and it was up to [1o57] to pull something out of his bag of tricks.
The first Mystery Challenge was a mechanical device with three locks ready to be picked (one was already unlocked), magnets to grab ferrous picks, and only slightly bomb-like in appearance. The next few years featured similar devices with more locks, better puzzles, and were heavy enough to make a few security officials believe [1o57] was going to blow up the Hoover dam.
With a few years of practice, [1o57] is turning crypto puzzles into an art. His DEFCON 22 badge had different lanyards that needed to be arranged to spell out a code. To solve the puzzle, you’ll need to talk to other people, a great way to meet one of [1o57]‘s goals of getting all the natural introverts working together.
Oh. This talk has its own crypto challenge, something [1o57] just can’t get out of his blood:

In case you haven’t been reading Hackaday for the last few weeks, we just had an amazing 10th anniversary party in Pasadena this weekend, full of workshops, talks, and a party that reportedly went until four in the morning. One of the amazing hackers we invited to give a talk was [Quinn Dunki], creator of Veronica, the modern 6502 computer stuffed inside an old radio.
We first saw Veronica a few years ago, but [Quinn] figures she’s been building her computer for about five years now. She’s a software developer by trade that decided one day to dip her toes into the murky seas of hardware development and build a computer from the ground up. She chose the 6502 as the brains of her contraption, laid out everything on single-sided boards etched in a kitchen, and connected everything with a backplane. Right now it has a USB keyboard, (technically a PS/2 keyboard with a USB plug), NES controllers, a VGA display, and a monitor and Pong in ROM. [Quinn]‘s goal was to build a computer that could program itself, and after five years, she’s accomplished that goal.
[Quinn] admits her software background was responsible for a few of her admittedly bad design choices; the VGA is generated by an ATMega microcontroller, working under the theory that if she could clock the micro fast enough, she could do VGA. She now believes an FPGA would have been a better choice for video output, but now that the video circuit is done, she probably won’t revisit that problem.
There is one thing missing from Veronica, and something that [Quinn] will be working on in the future: mass storage. Right now every program Veronica can run is either stored in ROM or entered via the keyboard. A hard drive is the next problem to solve, either with an SD card, or a Compact Flash or IDE hard drive.
I’ve been a huge fan of EMSL for quite some time now, and my recent field trip proved that it has earned the name Evil Mad Scientist Laboratories for a good reason. For instance, look at the reflection in the glass near the bottom and you’ll glimpse the hearse that [Lenore] and [Windell] have sitting in front of the shop. But stop at the threshold, inside there are delights that ate up a couple of hours without me even noticing. And they thought they were going to get work done that day.
Don’t judge me by my appearance. This is late afternoon on a summer Saturday in Sunnyvale. Why does that matter? Obviously summer Saturdays in Silicon Valley always start with the Electronics Swap Meet and Engineer’s breakfast! That was a ton of fun but if you’re doing it right it’s also a bit tiring. No worries, a shot of excitement came over me as soon as I walked in that front door.

I became aware of harmonics and the sound of different shaped waveforms early in my electronics career (mid 1970’s) as I was an avid fan of [Emerson Lake and Palmer], [Pink Floyd], [Yes], and the list goes on. I knew every note of [Karn Evil 9] and could hear the sweeping filters and the fundamental wave shapes underneath it.
I remember coming to the understanding that a square wave, which is a collection of fundamental and (odd) harmonics frequencies, could then be used to give an indication of frequency response. If the high frequencies were missing the sharp edges of the square wave would round off. The opposite was then true, if the low frequencies were missing the square wave couldn’t “hold” its value and the top plateau would start to sag.

Yeah, check out that line-up poster. We’re so lucky to have an unreal collection of talented people pitching in to make this event happen. This Saturday is going to be Epic! Good thing since we’re celebrating 10-years-of-Hackaday!
What’s that you say? You don’t live in Los Angeles and are going to miss out? We’ll be live-streaming the event on:
You should put this feed on in the background while you hone your solding skills on that project you’ve been meaning to finish.
We will also be recording and posting the talks so that you may watch at your leisure.
Here’s a quick run-through of all that we have going on:
The day will start with three workshops, the first is a tiny-robot build based on [shlonkin's] design. The second is a lockpicking workshop hosted by [datagram] and [Jon King]. And the third is a Lithium charger workshop and build hosted by [Todd Black].
The afternoon brings the mini-conference with major talks by [Ryan '1o57' Clarke], [Steve Collins], [Quinn Dunki], [Jon McPhalen], and [ThunderSqueak]. There will be Lighting Talks by [Tod Kurt] and [Arko], as well as special appearances by Hackaday head editors from the past decade.
In the evening we’ll move into party mode. Music is presented by [The Gentlemen Callers] with interactives by [Deezmaker] and [Two Bit Circus].
Of course there will be a handful of the Hackaday writers in town for the event as well. [Adam Fabio] will be leading the robot workshop, [James Hobson] will be leading a build-off throughout the day, and [Mike Szczys], [Brian Benchoff], and [Bil Herd] will be on hand to do whatever is needed.
If you are interested in attending there may still be tickets available. We have been sold out but we’ve asked anyone who is unable to attend to cancel their ticket so new tickets become available as that happens. Yep, fans of Hackaday are courteous people. Yet another reason to celebrate.

You may be used to seeing rack mounted equipment with wires going everywhere. But there’s nothing ordinary about what’s going on here. [Elecia White] and [Dick Sillman] are posing with the backbone servers they’ve been designing to take networking into the era that surpasses IPv6. That’s right, this is the stuff of the future, a concept called Content Centric Networking.
Join me after the break for more about CCN, and also a recap of my tour of PARC. This is the legendary Palo Alto Research Company campus where a multitude of inventions (like the computer mouse, Ethernet, you know… small stuff) sprang into being.

It is with great pleasure that we are able to announce the final slate of speakers for Hackaday’s 10th Anniversary on October 4th in Pasadena. There are still around 30 tickets left for the conference so get yours now!
The most recently confirmed speaker is a man of many names. [Ryan Clarke] may be better known as [LosT], [1o57], or [Lostboy]. For years he has been driving the flagship contest at DEFCON by generating cryptographic puzzles that run far and deep through the 4-day conference and beyond. His talk will venture into the art and science of putting together these challenges, and the lengths at which determined hackers will go to solve them. His site gets taken over each year for DEFCON, so you might want to explore his Twitter account if you’re looking to learn more about this mysterious figure.
The other four speakers have already been mentioned in the initial announcement and last week’s follow-up. [Steve Collins] will discuss how his early interest in hacking led him to become an engineer at NASA. [Quinn Dunki] will have her scratch-built Veronica computer on hand and explain the adventure of the impressive project. [ThunderSqueak] will help us wrap our minds around the concept of non-binary computing, and [Jon McPhalen] will present the benefits of multi-core embedded processing versus traditional interrupt-based design.
We can’t wait for this amazing afternoon of talks which is just one week from Saturday. We hope to see you there!
