Things are getting real now. Check the list below for the last round of confirmed speakers to the 2017 Hackaday Superconference. This brings our slate of speakers to 32, but we’re not done yet.
Hackaday is adding an extra day to the Superconference by starting the festivities on Friday. Again this year we have an excellent custom hardware badge in development. It’s hard to pull yourself away during the Supercon for badge hacking so this year you can check in on Friday and let the hacking begin. Since you’ll be in town early, we’re also throwing a party at Supplyframe office (minutes walk from the main venue) for all Supercon speakers and attendees.
But we’re still not done. 32 talks, an epic hardware badge, and an extra day of festivities, what else could there be you ask? Two things: workshops and the Hackaday Prize party. Supercon will play host to eight hardware workshops this year. We’ll announce workshop presenters and topics next week but I can tell you they’re superb this year!

We’re excited to announce the next batch of speakers for the 2017 Hackaday Superconference.
We are especially pleased to welcome Michael Ossmann as a speaker. He presented an RF design workshop at the 2014 Superconference which was sold out, standing room only, and still turned away dozens of people before becoming a hit on the Internet. This year he takes the stage with colleague Dominic Spill as they focus on infrared communications and the uses and abuses of such.
Dr. Christal Gordon threw down an incredible talk on biologically inspired sensors last year and we suspect she will outdo herself this year. Her talk will cover the fanciest of cutting-edge sensors and the trade-offs of selecting the new hotness for your designs. Coming out of this you will know when to go with a suite of tried and true components and when to make the leap to new tech.
Several of this year’s Hackaday Prize Judges will be on hand and presenting talks. In addition to Christal Gordon and Danielle Applestone (announced as a speaker last week), we’re thrilled to have Anouk Wipprecht — internationally known for her work in fashion and engineering, pushing the boundaries of how technology can interface with humans — as a speaker. Nadya Peek from the Center for Bits and Atoms who spoke at Supercon in 2016 with a harrowing tale of an impromptu engineering challenge in Shenzhen has confirmed that she will speak this year.
The ever-popular Sprite_TM will be at Supercon. He has a reputation for bringing the house down with fantastic presentations, be it the Tamagochi Matrix or the Tiniest Game Boy. And we are proud to present the Art Director for Hackaday — Joe Kim will be speaking about the curious connection between art and technology and how developments in one push the other forward.
Ever wonder about the air you’re breathing in the house or at work. So does Natalia Mykhaylova whose work begins to monitor and catalog that information. She will discuss the state of our HVAC systems and what it looks like to bring them into the information age.
Below you’ll find the confirmed speakers we’re announcing today. We’ll have more, as well as a list of confirmed talks next week. Get your ticket now, they will sell out.

For want of a better use of a spare Raspberry Pi Zero W and a set of LogitechZ-680 surround sound speakers, [Andre van Kammen] hacked them together to make them stream music playing from his phone.
It was stumbling across the Pi Music Box distribution that really got the ball rolling, and the purchase of a pHAT DAC laid the foundation. Cracking open the speakers’ controller case, [Kammen] was able to get 5V of power off some terminals even when the speakers were on standby — awesome! — which the Pi could use. Power and volume are controlled via the Pi’s GPIO pins with a diode to drop the voltage and prevent shorts.
Now, how to tell whether the speakers are on or off? Well, a pin on the display connector changes to 4.3V when it’s on, so wiring a 10k resistor and a diode to said pin is a hackable solution. Finishing off the wired connections, it proved possible to cram the pHAT DAC inside the controller case with the GPIO header sticking out the back to mount the Pi upon with no other external wires — double awesome!

You’ll find the best hardware talks at the Hackaday Superconference. This year, we received over 140 proposals for a few dozen speaking slots. Although we’re still working through the proposals, today we can announce a few of the accepted and confirmed speakers so far. Below you’ll find about a third of the total slate of speakers.

[Scott] had a simple problem – he was tired of leaning over his work bench to change the volume on his speakers. He desired a system that would readily allow him to switch the speakers on and off from a more comfortable distance. Not one to settle for the more conventional solutions available, [Scott] whipped up a RADAR-activated switch for his speaker system.
The build relies on a surprisingly cost-effective RADAR module available off the shelf, running in the 5.8GHz spectrum. At under $10, it’s no big deal to throw one of these into a project that requires some basic distance sensing. [Scott] decided to keep things simple – instead of going with a full-fat microcontroller to control the speakers, a 74HC590 IC was used to create a latch. Each time the RADAR module senses an object in close proximity, it toggles the state of the latch. The latch then controls a transistor that switches the power for the speakers.
Overall it’s a build that combines a modern integrated RADAR module with some very simple control logic to create a functional build. Of course, there’s so much more you can do with some 74-series logic. Video after the break.

If you have an interest in audio there are plenty of opportunities for home construction of hi-fi equipment. You can make yourself an amplifier which will be as good as any available commercially, and plenty of the sources you might plug into it can also come into being on your bench.
There will always be some pieces of hi-fi equipment which while not impossible to make will be very difficult for you to replicate yourself. Either their complexity will render construction too difficult as might be the case with for example a CD player, or as with a moving-coil loudspeaker the quality you could reasonably achieve would struggle match that of the commercial equivalent. It never ceases to astound us what our community of hackers and makers can achieve, but the resources, economies of scale, and engineering expertise available to a large hi-fi manufacturer load the dice in their favour in those cases.
The subject of this article is a piece of extreme high-end esoteric hi-fi that you can replicate yourself, indeed you start on a level playing field with the manufacturers because the engineering challenges involved are the same for them as they are for you. Electrostatic loudspeakers work by the attraction and repulsion of a thin conductive film in an electric field rather than the magnetic attraction and repulsion you’ll find in a moving-coil loudspeaker, and the resulting very low mass driver should be free of undesirable resonances and capable of a significantly lower distortion and flatter frequency response than its magnetic sibling.
