Building The Hackaday Superconference Badge

October 11, 2017 by Brian Benchoff 36 Comments

The best hardware conference is just a few weeks away. This is the Hackaday Superconference, and it’s two days of talks, an extra day of festivities, soldering irons, and an epic hardware badge. We’ve been working on this badge for a while now, and it’s finally time to share some early details. This is an awesome badge and a great example of how to manufacture electronics on an extremely compressed timetable. This is badgelife, the hardware demoscene of electronic conference badges.

So, what does this badge do? It’s a camera. It has games, and it’s designed by [Mike Harrison] of Mike’s Electric Stuff. He designed and prototyped this badge in a single weekend. On board is a PIC32 microcontroller, an OV9650 camera module, and a bright, crisp 128×128 resolution color OLED display. Tie everything together with a few buttons, and you have a badge that’s really incredible.

So, how do you get one? You’ve got to come to the Hackaday Superconference. This year we’re doing things a bit differently and opening the doors a day early to get the hacker village started with badge hacking topped off by a party that evening and everyone coming to Supercon is invited! This is a badge full of games, puzzles, and video capture and isn’t something to miss. We have less than 30 tickets left so grab your ticket now and read on.

BOM Cost Optimization And Tindie Badge Engineering

October 6, 2017 by Brian Benchoff 16 Comments

For the last few months, I’ve been up to my neck in electronic conference badges. This year, I created the single most desirable badge at DEF CON. I also built a few Tindie badges, and right now I’m working on the logistics behind the Hackaday SuperConference badge. Sit tight on that last one — we’re doing something really, really special next month.

Most badge projects are one-off production runs. This is to be expected from a piece of hardware that’s only meant to be distributed at a single event. The Tindie badge is different. It’s now a thing, and we’re building multiple badges for all the cons and conferences Hackaday and Tindie are attending for the rest of the year. This means I have the opportunity to do hardware revisions on the Tindie badge. Right now I’ve built three versions of the Tindie and we’ve distributed about two thousand of these kits at DEF CON, Maker Faire New York, and the Open Hardware Summit.

After about two thousand units, I think we finally have this down. This is how I designed three versions of hardware in as many months and cut the BOM cost of each badge in half. This is bordering on a marginally impressive piece of engineering, and a great lesson on BOM cost optimization.

Teaching Electronics With A Breadboard Badge

October 3, 2017 by Brian Benchoff 19 Comments

Over the last year, the production of homebrew electronic badges for conferences has exploded. This is badgelife — the creation of custom hardware, a trial by fire of manufacturing, and a mountain of blinky LEDs rendered in electronic conference badges. It’s the demoscene for hardware, and all the cool kids are getting into it.

At this year’s World Maker Faire in New York, there was a brand new badge given out by the folks at Consumer Reports. This badge goes far beyond simple swag, and if you take a really good look at it, you’ll see magic rendered in breadboards and wire.

The Consumer Reports breadboard badge is simple and apparently designed to introduce kids to the world of electronics like the old Radio Shack, ‘100-in-1 Electronics Projects’ kits. Unlike most of the ‘beginner badges’ we’ve seen, this isn’t a badge where you only solder a few LEDs and a battery holder to a PCB. This is a breadboard badge. This is hacking with 74-series logic. This is an impressive piece of engineering given away by Consumer Reports. No one saw this one coming. I don’t think anyone at Maker Faire realized there’s now a viable way to create breadboard badges.

Make A Badge When There Is No Badge Yet

August 19, 2017 by Jenny List 10 Comments

What do you do when your keenly anticipated hacker camp releases details of its upcoming badge and you really want to have a go at coding for it, but there are no badges for you to try yet? If you are [Artdanion], this is not a problem, you simply build your own.

He found his requirement to interface with genuine hardware exceeded the abilities of the emulator that the SHACamp 2017 badge team had thoughtfully provided, so he reached for breakout boards for the ESP32, the MPR121 touch sensor, and the e-ink display, and assembled his own clone on a piece of stripboard. Not only did it provide him with enough to develop his own apps, he found when he brought it to the event that the public release of the official firmware ran on it with only a few configuration tweaks. He had an official event badge, that wasn’t the event badge. Is this the first time this has been done? We think it might be.

The home-made badge is an impressive piece of work, but it ties into an observation we made at the end of our review of the official version of the SHA2017 badge. The use of an ESP32 with well-designed peripherals and a solid firmware means that this is a design that is likely to form the bedrock upon which some future badges are built. [Artdanion] has proved how straightforward it is to clone, we’d like to be so bold as to make the prediction that we’ll see more developments of this platform at future events. Meanwhile this home-made badge is a neat achievement, and we can only imagine the surprise of the SHA2017 badge team on being presented with a clone of their work for reflashing.

The Latest Hacker Camp Badge Comes From BornHack

August 15, 2017 by Jenny List 9 Comments

If you’re a fan of outdoor hacker camps, or if you’re a SHACamp attendee who’s still coming down from the event high, you may already know about the upcoming BornHack 2017 hacker camp on the Danish island of Bornholm, from the 22nd to the 29th of this month. It’s a smaller camp than many of the others on the calendar, but it makes up for that with a quite reasonable ticket price, a much longer duration, and a location that is a destination in itself.

Today we have news of the BornHack badge announcement, and though the details are a little sketchy it’s safe to say that there should be plenty there to keep attendees occupied. The irregularly-shaped PCB contains a Silicon Labs “Happy Gecko” EFM32 ARM Cortex M0 microcontroller, a 128×64 pixel OLED display, and the usual array of I/O lines. There is no information about its connectivity as it seems the BornHack folks prefer to run a teaser campaign, but we’d be surprised if there wasn’t some kind of wireless module on the reverse.

Barring a transportation miracle it’s unlikely that any of the Hackaday team will be making it to BornHack, but that’s our loss. It may not be one of the larger camps, but it looks to offer no less of the atmosphere you’d expect from a European hacker camp. At the time of writing there are still BornHack tickets to be had, so head on over to their website if you fancy a week at a hacker camp on a Danish island.

Hands On With The SHACamp 2017 Badge

August 14, 2017 by Jenny List 24 Comments

The badge has become one of the defining features of a modern hacker camp, a wearable electronic device that serves as both event computer and platform for some mild software and hardware hacking. Some events have had astoundingly sophisticated badges while others are more simple affairs, and the phenomenon has even spawned an ecosystem of unofficial badges which have nothing to do with the event in question.

The SHACamp 2017 badge is the latest to come the way of a Hackaday writer, and certainly contains enough to be taken as representative of the state of hacker camp badges in 2017. It doesn’t have a star turn like CCCCamp 2015’s software defined radio, instead it’s an extremely handy little computer in its own right.

Friday Hack Chat: Crypto Challenge

August 9, 2017 by Brian Benchoff 2 Comments

It’s the middle of August, and that means all the hackers are back from DEF CON, safe in their hoodies, with memories of smoke-filled casinos, interesting talks, and, most importantly, crypto challenges.

This year was an ‘off’ year for DEF CON. There was an official badge, but it wasn’t electronic (which no one expected), and there was no crypto challenge (which no one saw coming). Nevertheless, there was already a vibrant community of badge builders, and the crypto nerds of DEF CON were satisfied by PCB locks from the Crypto and Privacy village, Benders, and Darknet phone dials this year.

How were these crypto challenges constructed? That’s the subject of this week’s Hack Chat. This Friday, we’re going to be sitting down with a member of DEF CON’s Crypto and Privacy village on how these curious codes are constructed, how a winner is determined, and the techniques used to solve these challenges.

This week, we’ll be talking about how crypto challenges actually work, how to put crypto in firmware, on laser-engraved acrylic plates, and in silkscreen on a PCB. We’ll be talking about how crypto challenges are created, and how you solve them. Special attention will be paid to testing a crypto challenge; that is, how do you make sure it’s solvable when you already know how to solve it?

Although this Hack Chat is only going to last an hour, there’s no possible way we could cover all the tips, tricks, and techniques of creating a crypto challenge in that time. If you’d like some further reading, [L0sT] showed up at our 10th anniversary party to tell us he created the puzzles for DEF CON over the last few years.

Here’s How To Take Part:

Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. This Hack Chat will take place at noon Pacific time on Friday, August 11th. Don’t know when the Earth’s sun will be directly overhead? Here’s a time and date converter!

Log into Hackaday.io, visit that page, and look for the ‘Join this Project’ Button. Once you’re part of the project, the button will change to ‘Team Messaging’, which takes you directly to the Hack Chat.

You don’t have to wait until Friday; join whenever you want and you can see what the community is talking about.
