Electromagnetic Field’s Badge Hanging in the Balance

Making conference badges is a tough job. Unless you’re sitting on a gold mine, you have to contact a whole bunch of sponsors for help, work the parts that you can get into a coherent design, and do it all on the quick for a large audience. The EMF team is this close to getting it done, but they need some sponsorship for the assembly. If you know anyone, help them out! If they can’t line something up in the next two weeks, they’ll have to pull the plug on the badge entirely.

Electromagnetic Field is a summer-camp hacker convention / festival that takes place in England and is now in its third iteration. As with other big cons, the badge is a good part of the fun.

The 2016 EMF badge looks to be amazing. It’s powered by an ST STM32L4 low-power micro, a color LCD screen, a TI CC3100 WiFi radio module onboard, and a ridiculous number of other features including a gyro and magnetometer, and a giant battery. It’s also a testbed for the brand-new MicroPython, which aims to bring everyone’s favorite scripting language to embedded processors. In fact, they’ve largely built the MicroPython WiFi drivers for the badge.

If they can’t get a sponsor, all is not lost because everything is open source. We’ll all reap the benefits of their hard work. But that’s not the point. The point is that hundreds of hackers will be standing around in a field outside of London without the most audacious badge that we’ve seen designed dangling from their necks.
If you know anyone who can help, get in touch?

Navid Gornall Eats His Own Face

Navid Gornall is a creative technologist at a London advertising agency, which means that he gets to play with cool toys and make movies. That also means that he spends his every working hour trying to explain tech to non-technical audiences. Which is why he was so clearly happy to give a talk to the audience of hardware nerds at the Hackaday Belgrade conference.

After a whirlwind pastiche of the projects he’s been working on for the last year and a half, with tantalizing views of delta printers, dancing-flame grills, and strange juxtapositions of heat sinks and food products, he got down to details. What followed was half tech show-and-tell, and half peering behind the curtain at the naked advertising industry. You can read our writeup of the highlights after the video below.

Reinventing VHDL Badly

A few years ago, Philip Peter started a little pet project. He wanted to build his own processor. This really isn’t out of the ordinary – every few months you’ll find someone with a new project to build a CPU out of relays, logic chips, or bare transistors. Philip is a software developer, though, and while the techniques and theory of building hardware haven’t changed much in decades, software development has made leaps and bounds in just the past few years. He’s on a quest to build a CPU out of discrete components.

Search the Internet for some tips and tricks for schematic capture programs like KiCad and Eagle, and you’ll find some terrible design choices. If you want more than one copy of a very specific circuit on your board, you have to copy and paste. Circuit simulation is completely separate from schematic capture and PCB design, and unit testing – making sure the circuit you designed does what it’s supposed to do – is a completely foreign concept. Schematic capture and EDA suites are decades behind the curve compared to even the most minimal software IDE. That’s where Philip comes in. By his own admission, he reinvented VHDL badly, but he does have a few ideas that are worth listening to.

Meet Up with Hackaday this Saturday in San Mateo

We’ll be at Bay Area Maker Faire and we want to have a beer with you on Saturday night.

Two years ago we headed off to the Bay Area Maker Faire and thought we’d invite friends and acquaintances to congregate at a bar on Saturday night. Anyone who’s been to the Faire (or been through a harrowing weekend of working a booth) knows that a bar stool and frothy beverage are a great way to recuperate. The turnout was amazing, we easily filled up O’Neill’s Irish Pub with that first meetup, and the Hackaday BAMF Meetup was born. Last year we packed it to the seams. This year we’re planning for an even bigger turnout that will go late into the evening.

I’ve only ever heard one complaint about this event; the band is too loud. This year O’Neill’s doesn’t have a band lined up so everything seems to be coming up roses. Come hang out with us! If you RSVP we’ll buy your first beer. Bring your stories, your easily transported hacks to show off, and have fun with the eclectic and enthralling community that turns out for this, the greatest meetup on earth.

Hackaday Letter from the Editors

If this is the first you’ve heard about this year’s meetup, you should subscribe to our weekly newsletter. Every week, a Hackaday Editor writes about what’s been going on that week, and shares a few of the most interesting posts from the past seven days. You can sign up for it in the sidebar to the right or with that signup link I just shared. If you’d like to know what you’re getting yourself into, here’s the most recent newsletter which we sent out on Friday. It’s a mini Hackaday delivered to your mailbox.

Madison Maker Faire

Saturday was the first Madison Mini Maker Faire. In this case, it’s Madison, Wisconsin (sorry Madison, SD I didn’t mean to get your hopes up) where I live. Of course I’m not the only crazy hardware hacker in the area. As soon as I got there I almost tripped over Ben Heckendorn who also lives in the area.

ben-heck-gameboy

Check out that incredible Giant Game Boy the he was exhibiting. Okay, you think to yourself: Raspberry Pi and an LCD. Wrong! He’s actually using an FPGA to drive the LCD. Even cooler, it’s using an original Game Boy brain board, which the FPGA is connected to in order to translate the handheld’s LCD connector signals to work with the big LCD.

Hackaday At Hamvention

There are a few interesting Hackaday gatherings going on next weekend. The first is the Bay Area Maker Faire. Most of the Hackaday and Tindie crew will be in San Mateo next weekend, and we’re giving away free tickets to the Faire – a $70 value, free to Hackaday readersHackaday is crashing a pub on Saturday night. There’s also a super-secret meetup on Sunday. Don’t tell anyone.

On the other side of the country, there’s an even better convention for people who build stuff.. It’s Hamvention, the largest amateur radio meetup in North America. I’m going to be there. Find me and pick up some Hackaday swag. I’ll be posting to the Hackaday Twitter all weekend.

The main purpose of my visit is to document the immense swap meet. There will be over a thousand vendors hocking their wares, from antique radios to gauges and other electronic paraphernalia. It is the biggest draw to Hamvention, and by every account I’ve heard, it’s impossible to look at everything.

It might be impossible to look at everything, but apparently I’ve very good at separating the wheat from the chaff at ham swaps. During my last visit to the W6TRW swap meet in Redondo Beach, I found an UltraSPARC laptop (!), and a wooden modem from the mid 60s. On Friday, Saturday, and Sunday, it will be my job to document all the oddities of Hamvention.

Depending on how many people I meet at Hamvention, there might be a semi-official Hackaday get together after the show. The US Air Force Museum at Wright-Patterson would be cool, but Ihop or Denny’s would be far more realistic. Look for the guy in the Hackaday hoodie flying a Hackaday flag and he’ll give you some sweet stickers and swag.

Phoenix Perry: Forward Futures

There were a lot of very technical talks at Hackaday Belgrade. That’s no surprise, this is Hackaday after all. But every once in a while it’s good to lift our heads up from the bench, blow away some of the solder smoke, and remind ourselves of the reason that we’re working on the next cool project. Try to take in the big picture. Why are you hacking?

image5[Phoenix Perry] raised a lot of big-think points in her talk, and she’s definitely hacking in order to bring more women into the field and make the creation of technology more accessible to everyone. Lofty goals, and not a project that’s going to be finished up this weekend. But if you’re going to make a positive difference in the world through what you love to do, it’s good to dream big and keep the large goal on your mind.

[Phoenix] is an engineer by training, game-coder by avocation, and a teacher for all the right reasons. She’s led a number of great workshops around the intersection of art and technology: from physical controllers for self-coded games to interactive music synthesis devices disguised as room-sized geodesic domes. And she is the founder of the Code Liberation Foundation, a foundation aimed at teaching women technology through game coding. On one hand, she’s a hacker, but on the other she’s got her eyes on a larger social goal.
