Sophi Kravitz Talks The Tech Behind Art

Hackaday’s own mythical beast, Sophi Kravitz makes some amazing collaborative tech-art pieces. In this talk, she walks us through four of the art projects that she’s been working on lately, and gives us a glimpse behind the scenes into the technical side of what it takes to see an installation from idea, to prototype, and onto completion.

Watch Sophi’s talk from the Hackaday | Belgrade conference and then join us after the jump for a few more details.

Hackaday Belgrade was Hardware Center of Universe on Saturday

One of my favorite conversation from Saturday’s Hackaday | Belgrade conference was about border crossing. This guy was saying the border station coming into Serbia needed a separate lane with the Skull and Wrenches on the digital sign since it was obvious the two cars in front of them were also packed with people coming to the con (and all the custom hardware that travels with the Hackaday crowd). The thought of caravans full of hardware hackers were on their way to this epic gathering.

We packed the place, selling at least 50 tickets past our limit in the last few weeks to people who just wanted to get in and didn’t mind not being able to get their hands on one of the sweet badges. I recall meeting people who came from Romania, Bulgaria, Greece, Slovenia, Spain, Italy, Switzerland, USA, Germany, France, UK, and of course Serbia. If you were there and I missed your country let us know in the comments.

Obviously the main event is the incredible slate of talks that happen at our conferences. We had great presenters at last November’s SuperConference — our first every conference — so we’re delighted to say that our second was just as good. (We anticipate a third this fall.) Hackaday is so thankful for all of the speakers who donated their time and talent to share their knowledge and experience with our worldwide community.

Among my favorites were Seb Lee-Delisle’s talk on his many huge laser and projection mapping installations, Mike Harrison’s drilldown of the absolutely stunning engineering that went into Eidophor projector systems, Dejan Ristanovic’s fascinating talk about the on-again off-again history of Internet in Serbia, Sophi Kravitz’s collaborative work with polarizing materials, and Voja Antonic’s talk on the many trials of designing the conference badge which cleared out the world’s stock of more than one type of Kingbrite LED modules. If you missed the live stream of these talks don’t worry, we recorded all of them. It will take a bit of time to edit and post them so keep your eyes on the front page.

Announcing Hackaday Belgrade’s Talks and Speakers

Hackaday is hosting a hardware conference in Belgrade on April 9th. This is arguably our first-ever European conference, and for the last few months we’ve been putting together a hackable conference badge, a list of speakers, and a set of hands-on workshops. Now, we’re finally ready to announce the workshops and talks for Hackaday | Belgrade. You can check out the scheduled talks and workshops below.

Tickets for Hackaday | Belgrade are still available, and tickets for the workshops will open up today. Tickets are also cheap – $35 for a regular ticket, and about $10 and $30 for the robot and DIY musical toy workshops, respectively. The workshop tickets are only to cover material cost, and you’ll get to take your project home with you.

The conference will be a blast. There will be bands and DJs, badge hacking competitions, and ten hours of talks and workshops. If you’re going, or are still on the fence, hang out on the event page to get the inside info on a few Hackaday events that will happen the night before and the day after.

Packed with Amazing People

mike
If you don’t recognize the name you will almost certainly recognize his internet persona: Mike’s Electric Stuff. He’s been regularly featured on the front page of Hackaday as he churns out a unique body of work like tearing down Flir’s low-end gear to discover it’s identical to their high-end offerings.

Hackaday is a global community and that is what makes Hackaday | Belgrade spectacular. We are still accepting proposals for talks through February 15th but haven’t yet made all of the decisions regarding presenters — you should submit a proposal! We’ll publish an article about all of the presenters once we have wrapped up the call for proposals. Expect to hear back about this around February 22nd.

One thing I am very excited about is that Mike Harrison will be at the conference. His talk will cover his exploration of an absurdly expensive and complicated relic which was used in the 1950’s for large-format video projection. Mike’s ability to unlock understanding of complex (and awesome) electronics is quite amazing; this talk is not to be missed. But Mike is just one of a dozen presenters from all over Europe. Several members of the Hackaday crew will be on hand and the venue will be packed with hundreds of fellow hardware hackers. You won’t want to miss this.

You Will Hack This Badge

hackaday-belgrade-badge-prototypeThis is the first Hackaday event where we have an active electronic badge. Voja Antonic has been hard at work with the design and just published the first details a few days ago.

The central feature of the badge is an 8×16 LED matrix driven by a PIC microcontroller. It’s running a USB bootloader which will let you flash your own custom code without needing a programmer. We were speaking with some of our friends over at Microchip regarding the bootloader and they offered to supply all the microcontrollers for the badge, an offer we were happy to accept.

Voja has already programmed the first demo application seen here, it’s Tetris written in assembly language. Impressive!

We were overwhelmed by the popularity of badge hacking at the Hackaday SuperConference last November. You can bet that badge hacking will be one of the most popular activities at Hackaday Belgrade. I have written a hardware emulator to work on some animations. It uses the SDL2 library to display the LED matrix and take three button inputs (the final badge design will have four buttons arranged in up/down/left/right configuration). Our hope is to host a demoscene competition that is open to anyone, whether you can attend the conference or not. More on that later.

Live Music and Hacking

As the evening sets in and the talks wind down, we have lined up bands and DJs to take the stage and carry us well into night. You won’t have to stop the badge hacking or anything else that you’re into, but you won’t have to solder in silence either.

As you can tell, this conference goes way beyond talks. This is hardware culture and you’ve just got to be there. Running from 10am until 2am, there’s more than enough to keep you occupied for one day. But make sure to hang out on the event page to get inside information on other non-formalized social events that will happen the night before and the day after. See you in Belgrade!

Developed on Hackaday : HaDge update – it’s a HACK

Work on HaDge – the Hackaday con badge, continues in bits and spurts, and we’ve had some good progress in recent weeks. HaDge will be one conference badge to use at all conferences, capable of communicating between badges.

Picking up from where we left off last time, we had agreed to base it around the Atmel D21, a 32-bit ARM Cortex M0+ processor. To get some prototype boards built to help with software development, we decided to finish designing the HACK before tackling HaDge. HACK is a project that [Michele Perla] started that we have sort of assimilated to act as the prototyping platform for HaDge. We wanted a compact micro-controller board and hence opted for the SAM D21E – a 32 pin package with 26 IO’s.

[Michele Perla] had earlier designed HACK based on the larger 32 pin SAM D21G and used Eagle to hack-brddraw the schematic and layout. Using the Eagle to KiCad script, he quickly converted the project and got on to making the board layout. I took up the rear guard, and worked on making his schematic (pdf) “pretty” and building up a schematic library of symbols. While [Michele] finished off the board layout, I worked on collecting STEP models for the various footprints we would be using, most of which I could get via 3dcontentcentral.com. The few I couldn’t were built from scratch using FreeCAD. The STEP models were converted to VRML using FreeCAD. Using [Maurice]’s KiCad Stepup script, we were able to obtain a complete STEP model of the HACK board.

HACK is now ready to go for board fabrication and assembly. We plan to get about 20 boards made and hand them out to developers for working on the software. The GitHub repository has all the current files for those who’d like to take a look – it includes the KiCad source files, PDFs, gerbers, data sheets and images. The board will be breadboard compatible and also have castellated pads to allow it to be soldered directly as a module. Let us know via group messaging on the HACK project page if you’d like to get involved with either the software or hardware development of HaDge.

In a forthcoming post, we’ll put out ideas on how we plan to take forward HaDge now that HACK is complete. Stay tuned.

Shmoocon 2016: The Best Conference Booth You’ll Ever See

Shmoocon is here, and that means a dozen or so security companies have bought a booth and are out to promote themselves. Some are giving out shot glasses. One is giving out quadcopters. It is exceedingly difficult to stand out in the crowd.

At least one company figured it out. They’ve built a game so perfect for the computer literate crowd, so novel, and so interesting it guarantees a line in front of their booth. Who are they? Fortego, but that’s not important right now. The game they’ve created, BattleBits, is the perfect conference booth.

The game play for BattleBits is as simple as counting to two. You’re presented with an eight-bit hexidecimal number, and the goal is to key them into a controller with eight buttons for 1, 2, 4, 8, 16, 32, 64, and 128. The answer for 0x56 is 01010110, and the answer for 0xFF is mashing all the buttons.

BattleBits Screenshot

To anyone not familiar with hex, there’s actually a rather handy trick to the game: you only need to memorize 16 different numbers. Hexadecimal numbers are easily broken up into nibbles, or groups of four bits. All you need to do is solve one hexadecimal digit at a time.

The controllers, or ‘decks’ as they’re, are built around a BeagleBone and a custom cape running a mishmash of Javascript and Python. When the game starts the player or players are presented with random bytes in hexadecimal format. Input the right bits in the shortest amount of time and you’ll work your way up the leader board.

This is by far the best conference booth I’ve ever seen. The creator of the BattleBits hardware, [Riley Porter], says he’ll be releasing the design files and code for this game so anyone can make one, something we really look forward to.

[Riley] also got a video of someone entering nibbles super, super fast.

Hackaday Links: November 8, 2015

[Burt Rutan] is someone who needs no introduction. Apparently, he likes the look of the Icon A5 and is working on his own version.

Earlier this week, the US Air Force lost a few satellites a minute after launch from Barking Sands in Hawaii. This was the first launch of the three stage, solid fueled SPARK rocket, although earlier versions were used to launch nuclear warheads into space. There are some great Army videos for these nuclear explosions in space, by the way.

[Alexandre] is working on an Arduino compatible board that has an integrated GSM module and WiFi chip. It’s called the Red Dragon, and that means he needs some really good board art. The finished product looks good in Eagle, and something we can’t wait to see back from the board house.

The Chippocolypse! Or however you spell it! TI is declaring a lot of chips EOL, and although this includes a lot of op-amps and other analog ephemera (PDF), the hi-fi community is reeling and a lot of people are stocking up on their favorite amplifiers.

[Jeremy] got tired of plugging jumper wires into a breadboard when programming his ATMega8 (including the ‘168 and ‘328) microcontrollers. The solution? A breadboard backpack that fits right over the IC. All the files are available, and the PCB can be found on Upverter.

In case you haven’t heard, we’re having a Super Conference in San Francisco later this week. Adafruit was kind enough to plug our plug for the con on Ask an Engineer last week.
