This Weekend: The Greatest Hardware Conference

October 31, 2018 by Brian Benchoff 4 Comments

The Hackaday Superconference is this weekend and it’s the greatest hardware con on the planet. Tickets are completely sold out, but you can still get in on the fun by watching the livestream and joining Supercon chat.

For everyone who will be here in person, the entire Hackaday crew is busy as beavers preparing for your arrival. We’re assembling badges, rigging AV for the talks, stuffing goodie bags, calling caterers, and taping cables to the floor. This is by far the biggest Superconference yet.

Doors open at 9 am Friday at the Supplyframe HQ. This is your first chance to get your hands on the fantastic Supercon Badge that’s a freakin’ computer. The day is filled with badge hacking, workshops, badge talks, and a launch party. [Rich Hogben] and [Andrew Bakhit] will be doing live IDM sets on Friday night, as we celebrate into the wee hours of the morning.

Saturday, doors open at 9 am over at the Supplyframe Design Lab as we turn on the livestream and get the main event under way with over 50 speakers and workshops. Badge hacking continues throughout the weekend, and this year we’ve added the SMD Soldering Challenge to the fun. There will be meetups during Supercon; the Tindie meetup and the amateur radio meetup are both Saturday at 1 pm.

Vinduino Water-Smart Farming – Now With LoRa!

October 25, 2018 by Roger Cheng 9 Comments

Our five rounds of Hackaday Prize 2018 challenges have just wrapped up, and we’re looking forward to see where the chips fall in the final ranking. While we’re waiting for the winners to be announced at Hackaday Superconference, it’s fun to take a look back at one of our past winners. Watch [Reinier van der Lee] give the latest updates on his Vinduino project (video also embedded after the break) to a Hackaday Los Angeles meetup earlier this year.

Vinduino started with [Reinier]’s desire to better understand what happens to irrigation water under the surface, measuring soil moisture at different depths. This knowledge informs more efficient use of irrigation water, as we’ve previously covered in more detail. What [Reinier] has been focused on is improving usability of the system by networking the sensors wirelessly versus having to walk up and physically attach a reader unit.

His thought started the same as ours – put them on WiFi! But adding WiFi coverage across his entire vineyard was not going to be cost-effective. After experimenting with various communication schemes, he has settled on LoRa. Designed to trade raw bandwidth for long range with low power requirements, it is a perfect match for a network of soil moisture sensors.

In the video [Reinier] gives an overview of LoRa for those who might be unfamiliar. Followed by results of his experiments integrating LoRa functionality into Vinduino, and ending with a call to action for hackers to help grow the LoRa network. It sounds like he’s become quite the champion for the cause! He’s even giving a hands-on workshop at Supercon where you can build your own LoRa connected sensor. (Get tickets here.)

We’re always happy to see open-source hardware projects like Vinduino succeed, transitioning to a product that solve real world problems. We know there are even more promising ideas out there, which is why Hackaday’s sister company Tindie is funding a Project to Product program to help this year’s winners follow in Vinduino’s footsteps. We look forward to sharing more success stories yet to come.

Hackaday Superconference: Tickets And Proposals

July 9, 2018 by Mike Szczys 15 Comments

Get your tickets now for the 2018 Hackaday Superconference. Join us November 2nd-4th in Pasadena, California!

This is the ultimate hardware conference. Hackers, designers, and engineers from all over the world converge — from the greenest beginners to those who have made history with their designs. This is the Hackaday community, these are your people, and you need to be here. Supercon is your chance to experience all things involved in hardware creation — the weekend is filled with unparalleled talks and workshops — but the experience of Supercon transcends the organized event. We call it a conference but it’s truly a hacker village with a who’s-who of hackerdom in attendance.

Call for Proposals

We want you to present a talk (or a workshop) at this year’s Supercon! Please submit your proposal using this form.

The number one question we get about CFP is “I’m excited about X, should I submit a proposal?” The answer is yes. Don’t self-eliminate — if you have an idea for a talk we want to hear from you. Supercon is a flat conference, your proposal will be judged on the idea and how you plan to present it, not on how many other amazing speaking slots you’ve secured.

To help get your mind moving about topics, we suggest that you consider this list of themes your talk might fit into: Engineering Heroics, Prototyping, Research, Product Development, Full-Stack Fabrication, and of course Wildcard.

Tickets! Get Your Tickets Here!

Are you a true believer? We’ve just opened up the Call for Proposal today, so we can’t tell you who’s speaking or what workshops will take place. However, we suspect there are many of you ready to take the plunge right now. Those first 96 true believers get an incredibly low ticket price of $128.

Standing room only during a 2017 Hackaday Supercon talk

Even at full price, the admission fee is an incredible value (see for yourself). Each ticket comes with admission for all three days, a custom hardware badge to hack on, admission to the Friday kick-off party and Saturday Hackaday Prize party, food and beverage throughout the conference, and much more.

This is the fourth year we’ve hosted the Hackaday Superconference. You can check out all of the talk videos from last year, there’s a slew of articles on the event, and of course an incredible hardware hacking scene throughout. In large part, the packed and jovial community atmosphere is why we’ve added Friday as a full day of workshops and badge hacking!

Get your ticket and book your travel. We look forward to hanging out with a huge chunk of the Hackaday community at Supercon!

Alan Yates: Introduction To Vacuum Technology

December 7, 2017 by Jenny List 17 Comments

When we mention vacuum technology, it’s not impossible that many of you will instantly turn your minds to vacuum tubes, and think about triodes, or pentodes. But while there is a lot to interest the curious in the electronics of yesteryear, they are not the only facet of vacuum technology that should capture your attention.

When [Alan Yates] gave his talk at the 2017 Hackaday Superconference entitled “Introduction To Vacuum Technology”, he was speaking in a much more literal sense. Instead of a technology that happens to use a vacuum, his subject was the technologies surrounding working with vacuums; examining the equipment and terminology surrounding them while remaining within the bounds of what is possible for the experimenter. You can watch it yourself below the break, or read on for our precis.

In the first instance, he introduces us to the concept of a vacuum, starting with the work of [Evangelista Torricelli] on mercury barometers in the 17th century Italy, and continuing to explain how pressure, and thus vacuum, is quantified. Along the way, he informs us that a Pascal can be explained in layman’s terms as roughly the pressure exerted by an American dollar bill on the hand of someone holding it, and introduces us to a few legacy units of vacuum measurement.

In classifying the different types of vacuum he starts with weak vacuum sources such as a domestic vacuum cleaner and goes on to say that the vacuum he’s dealing with is classified as medium, between 3kPa and 100mPa. Higher vacuum is beyond the capabilities of the equipment available outside high-end laboratories.

Introduction over, he starts on the subject of equipment with a quick word about safety, before giving an overview of the components a typical small-scale vacuum experimenter’s set-up. We see the different types of vacuum gauges, we’re introduced to two different types of service pumps for air conditioning engineers, and we learn about vacuum manifolds. Tips such as smelling the oil in a vacuum pump to assess its quality are mentioned, and how to make a simple mist trap for a cheaper pump. There is a fascinating description of the more exotic pumps for higher vacuums, even though these will be out of reach of the experimenter it is still of great interest to have some exposure to them. He takes us through vacuum chambers, with a warning against cheap bell jars not intended for vacuum use, but suggests that some preserving jars can make an adequate chamber.

We are then introduced to home-made gas discharge tubes, showing us a home-made one that lights up simply by proximity to a high voltage source. Something as simple as one of the cheap Tesla coil kits to be found online can be enough to excite these tubes, giving a simple project for the vacuum experimenter that delivers quick results.

Finally, we’re taken through some of the tools and sundries of the vacuum experimenter, the different types of gas torches for glass work, and consumables such as vacuum grease. Some of them aren’t cheap, but notwithstanding those, he shows us that vacuum experiments can be made within a reasonable budget.

Superconference Interview: Alan Yates

August 26, 2017 by Brian Benchoff 5 Comments

In 2015, virtual reality was the future, which means we should all have it right now. One of the most technologically impressive VR sets is the HTC Vive, an amazing piece of kit that’s jam-packed with sensors and has some really cool tech going on inside it.

One of the developers of the HTC Vive and the ever-important ‘Lighthouse’ position sensors is [Alan Yates]. He’s of Valve and gave a talk at last year’s Superconference on Why the Lighthouse Can’t Work. Being able to determine the absolute position of the Valve’s headset is hard, but absolutely necessary for VR. Anything else would be an incomplete VR experience at best, and give you nausea at worst.

We sat down with [Alan] after his talk last year, and now that interview is up. You can check that out below.

Superconference Interview: Ben Krasnow

August 16, 2017 by Brian Benchoff 2 Comments

Ben Krasnow is a consummate prototyper. He’s built a machine that makes the perfect chocolate chip cookie, he has a ruby laser, and he produces his own liquid nitrogen in-house because simply filling up a dewar is too easy. If you need a prototype, Ben is the guy to talk to.

Ben gave a talk at last year’s Hackaday Superconference on prototyping quickly and verifying technical hypotheses. The philosophy can be summed up simply as, ‘Build First, and Ask Questions Later’. This philosophy served him well when he wanted to see if backscatter x-ray machines were actually more effective than metal detectors at TSA checkpoints. The usual bean-counter protocol for answering this question would be to find an x-ray expert, wait weeks, pay tens of thousands of dollars, and eventually get an answer. Ben simply built his own backscatter x-ray machine from parts sourced on eBay.

After the talk, we asked Ben about the limits of this philosophy of building first and asking questions later. With the physical and mental toolset Ben has, it’s actually easy to build something that can get in the ballpark of answering a question. The problem comes when Ben needs to prove something won’t work.

Answering this question is all a matter of mindset. In Ben’s view, if a prototype works, a hypothesis is verified. Even if it’s a complete accident, he’s totally okay with the results. Some of his other colleagues have an opposite mindset — if a quick and dirty prototype doesn’t work, a research hypothesis is verified.

This rapid-proof-of-concept mindset is something we see a lot in the Hackaday audience, and we know there are some of you out there who have a mind and garage that is at least as impressive as Ben’s. We’ve extended the Call for Proposals for the 2017 Hackaday Superconference. If you have a story about rapid prototyping or just making the perfect chocolate chip cookie with robots, we want to hear about it. Tickets are still available for the Superconference in Pasadena, California on November 11th and 12th.
