Super Smash Bros. Melee is a multiplayer fighting game released for the Nintendo GameCube in 2001. For the last decade and a half, it has become one of the premier fighting game eSports, and it is the reason Nintendo still makes a GameCube controller for the Wii U. Smash Melee has an intense following, and for years the idea of an AI that could beat top-tier players at Melee was inconceivable – the game was just far too complex, the strategies too demanding, and the tactics too hard.
[Dan] a.k.a. [AltF4] wasn’t satisfied that a computer couldn’t beat players at Melee, and a few years ago started work on the first Melee AI that could beat any human player. He just released Smashbot at this year’s DEF CON, and while the AI is limited, no human can beat this AI.
If I can offer one piece of advice to the Hackaday readership, it is this: Never, ever, be the sole member of your hackerspace’s board that owns a large station wagon, unless you relish the thought of packing an entire hacker camp village into your vehicle and transporting it halfway across the country in the blazing August heat.
I’ve done my laundry, aired my tent, and just sorted the contents of a brace of Tesco bags into several categories: rubbish, food, camping gear and interesting stuff. As I write this, yesterday was teardown day for Electromagnetic Field 2016, an event that bills itself as “a non-profit UK camping festival for those with an inquisitive mind or an interest in making things: hackers, artists, geeks, crafters, scientists, and engineers”, and this is a personal account of the event from the point of view of both being part of the Oxford Hackspace village and of waving the flag for Hackaday and Tindie.
DEF CON has become known for the creative electronic badges, and now we get to see a variety of them dangling from lanyards every year. This year, the Queercon badge stood out as the one that got the most people asking “where did you get that?!” Once again, [Evan Mackay], [George Louthan], [Jonathan Nelson], and [Jason Painter] delivered an awesome badge for this con-within-a-con for LGBT hackers and their friends.
The badge is a squid shape, with a nifty clear solder mask, printed on black FR4, and routed with natural curved traces. The squid eyes consist of sixty cyan LEDs, with RGB LEDs on the tentacles. The eyes make expressions, and the tentacles light up with a selectable pattern. Hitting the “ink” button shoots your pattern out to all nearby devices using the 2.4 GHz radio on board, and a set of small connectors can be used to “mate” with other badges to learn patterns. Yes, the Queercon badge always has suggestive undertones.
After playing with it for the whole con, we think this badge has some good lessons for electronic badge designers:
This badge used a phototransistor as a light sensor to measure ambient light and set the brightness accordingly. With over 60 LEDs, this helped the two AA batteries last for nearly the entire conference.
This badge has a power switch. That switch turns the badge off. This probably sounds very obvious, but it’s also unfortunately uncommon on electronic badges. The switch means people turn the badge off at night, and don’t have to yank batteries when firmware glitches.
The badge had two expansion ports on the squid’s head for adding hats. These were given power, and the connector spec was published before the event. Our favourite? A unicorn horn with a rainbow LED inside.
Social Badges are Fun
This has been the fourth Queercon badge in a row that communicated with other badges to unlock things. This is actually a neat way to get people to interact, and leads to a whole host of suggestive puns. Badginal intercourse, anyone?
We’ve heard that next year’s badge is already in the works, and we look forward to seeing what these folks come up with next. For now, you can grab all the hardware design files and get inspired for your own electronic badge build.
A few years ago, [Kingpin] a.k.a. [Joe Grand] (A judge for the 2014 Hackaday Prize) designed the most beautiful electronic prank ever. The BSODomizer is a simple device with a pass-through connection for a VGA display and an infrared receiver. Plug the BSODomizer into an unsuspecting coworker’s monitor, press a button on a remote, and watch Microsoft’s blue screen of death appear. It’s brilliant, devious, and actually a pretty simple device if you pick the right microcontroller.
The original BSODomizer is getting a little long in the tooth. VGA is finally dead. The Propeller chip used to generate the video only generates text, and can’t reproduce Microsoft’s fancy new graphical error screens. HDMI is the future, and FPGAs have never been more accessible. For this year’s DEF CON, [Kingpin] and [Zoz] needed something to impress an audience that is just learning how to solder. They’ve revisited the BSODomizer, and have created the greatest hardware project at this year’s DEF CON.
This year’s DEF CON badge is electronic, and there was much celebrating. This year’s DEF CON badge has an x86 processor, and there was much confusion.
The badge this year, and every year, except badges for 18, 17, 16, 15, and 14, designed by [Joe Grand], and badges from pre-history designed by [Dark Tangent] and [Ping], was designed by , and is built around an x86 processor. Specifically, this badge features an Intel Quark D2000 microcontroller, a microcontroller running at 32MHz, with 32kB of Flash and 8kB of RAM. Yes, an x86 badge, but I think an AT motherboard badge would better fulfill that requirement.
As far as buttons, sensors, peripherals, and LEDs go, this badge is exceptionally minimal. There are eight buttons, laid out as two directional pads, five LEDs, and a battery. There’s not much here, but with a close inspection of the ‘chin’ area of the badge, you can see how this badge was programmed.
As with any  joint, this badge features puzzles galore. One of these puzzles is exceptionally hard to photograph as it is in the bottom copper layer. It reads, “nonpareil bimil: Icnwc lsrbcx kc htr-yudnv ifz xdgm yduxnw yc iisto-cypzk”. Another bottom copper text reads, “10000100001 ΣA120215”. Get crackin’.

VCF West is happening this Saturday and Sunday at the Computer History Museum in Mountain View, CA. This on of our favorite events; a celebration of the hardware that paved the way for our modern world. VCF attracts an impressive amount of rare and interesting computers and other technology items. That hardware doesn’t make it to the festival on its own. The people at VCF — exhibitors, speakers, attendees, etc — are themselves an incredible collection of stories from salvage and restoration to the inside story on the teams that made the computers in the first place. Check out some of Brian Benchoff’s coverage of VCF East earlier this year.
I ran into Vintage Computer Federation President Evan Koblentz ten days ago and he shared an interesting anecdote I think you’ll enjoy. Bil Herd was a featured speaker at VCF East a few years back. He was the Senior Design Engineer behind the Commodore C128 — obviously a fascinating person to headline the event. The year after Bil spoke at the festival, Evan as surprised to run into him wandering around the event again. Bil didn’t just want to speak, he wanted to see all the cool stuff and has attended, spoken, and conducted workshops at several of the festivals since.
Who will show up this year is anyone’s guess. But we know this event is incredible and you will be amazed at who you run into. It is important to recognize where our technology comes from, to celebrate those who made it happen, and to encourage young people to start on the path to becoming a computer engineering wizard. For all of these reasons we are happy to be sponsoring VCF West. On the inside cover of every festival program you’ll find this epic art by our Illustrator, Joe Kim. You can also click the image on the right to embiggen.
Joshua Vasquez will on hand for Hackaday at VCF West. He’s looking for the best bits to feature on our front page. If you want get a hold of him to show off your wares, or to grab some excellent Hackaday stickers, hit him up on Hackaday.io.
There’s a problem with software defined radio. It’s not that everyone needs to re-learn what TEMPEST shielding is, and it’s not that Bluetooth is horribly broken. SDR’s biggest problem is one of bandwidth and processing. With a simple USB TV Tuner, you can listen in on aircraft, grab Landsat images from hundreds of miles up, or sniff the low-power radios used in Internet of Things things. What you can’t do is make your own WiFi adapter, and you can’t create your own LTE wireless network. This is simply a problem of getting bits from the air to a computer for processing.
At HOPE last weekend, the folks behind the very capable LimeSDR and a new company working with Lime’s hardware laid out the possibilities of what software defined radio can do if you make a link to a computer very fast, and add some processing on the SDR itself.
