Hackaday Munich: DJ Muallem, Workshop Info, and More

DJ Muallem

btn-get_ticketsIf you don’t have your ticket to the Hackaday Prize Party at Hackaday Munich you better scramble for one. We are excited to announce that [muallem] is the DJ for the event. He is the driving force behind the music at the Bob Beaman Club in Munich and is sure to deliver a set to remember. Don’t take our word for it, we’ve been cranking his Soundcloud channel for a couple of days now and it’s hard to wait the two weeks left before the party starts.

Workshop details whether you have a ticket or not

For those able to show up during the afternoon we have started to post details about the workshops. One point of confusion has been the All-day tickets versus the Workshop tickets. Here’s a rundown:

  • Workshop tickets were limited based on the hardware we are able to bring to the event with us.
  • All day tickets are welcome to participate in the workshops if you bring your own hardware to hack. Of course you are also welcome to come and watch, visit, or work on a completely separate hardware hack of your own!

If you have a ticket you’ll want to check out the details about getting a head start (by pre-loading embedded development software and learning a bit about the challenges). If you don’t have a workshop ticket we’re recommending hardware you can bring in order to participate.

So far we’ve posted about the Roboto and Moog workshops but will add details about Reverse Engineering and Computer Vision workshops soon!

The Hackaday Prize: Space Trip or Cash?

There has been a brewing debate about whether the winner of The Hackaday Prize (who will be revealed live at Hackaday Munich) will take the Trip to Space or grab the $196,418 in cash. Tell us which what you would do and why.

The Hackaday Prize: Interview With A ChipWhisperer

chipwhisperer

Every finalist for The Hackaday Prize has some aspect of it that hasn’t been done before; finding the chemical composition of everything with some 3D printed parts is novel, as is building a global network of satellite ground stations with off the shelf components. [Colin]‘s ChipWhisperer, though, has some scary and interesting implications. By looking inside a microcontroller as its running, the ChipWhisperer is able to verify – or break – security on these chips. It’s also extremely interesting and somewhat magical being able to figure out what data a chip is processing simply by looking at its power consumption.

We have no idea who the winner of The Hackaday Prize is yet, and I’m hoping to remain ignorant of that fact until the party two weeks from now. Until then, you can read the short interview with [Colin O'Flynn], or check out his five-minute video for the ChipWhisperer below:

New to the Store: Bulbdial Clock and Free Shipping Option

New to the Hackaday Store today is the Bulbdial Clock by Evil Mad Scientist Laboratories. I’ve had my eye on this kit for years and finally pulled the trigger after visiting [Lenore] and [Windell] at their shop a few weeks back. Assembling the beautifully-engineered kit was a delight, and I have a handful of hacks I’d like to try out — some of which I mentioned in the product description.

Free shipping based on order price

We always listen to what the Hackaday community has to say. After receiving several requests for better international shipping prices we came up with a way to ease the pain for orders no matter where they are headed. All domestic orders totaling $25 or more now receive free shipping. All international orders totaling $50 or more now receive free shipping.

Is there anything else you’d like to see different about the store? How about a hackable product you think we should stock? We’re listening via the store contact form.

The Hoverboard You Can Build At Home

Press embargoes lifted today, heralding the announcement of the world’s first hoverboard. Yes, the hovering skateboard from Back to the Future. It’s called the Hendo hoverboard, it’s apparently real, and you can buy one for $10,000. If that’s too rich for your blood, you can spend $900 for a ‘technology demonstrator’ – a remote-controlled hovering box powered by the same technology.

Of course the world’s first hoverboard is announced to the world as a crowd funding campaign, so before we get to how this thing is supposed to work, we’ll have to do our due diligence. The company behind this campaign, Arx Pax Labs, Inc, exists, as does the founder. All the relevant business registration, biographical information, and experience of the founder and employees of Arx Pax check out to my satisfaction. In fact, at least one employee has work experience with the innards of electric motors. At first glance, the company itself is actually legit.

The campaign is for a BttF-style hoverboard, but this is really only a marketing strategy for Arx Pax; the hoverboards themselves are admittedly loss leaders even at $10,000 – the main goal of this Kickstarter is simply to get media attention to the magnetic levitation technology found in the hoverboard. All of this was carefully orchestrated, with a ‘huge event’ to be held exactly one year from today demonstrating a real, working hoverboard. What’s so special about demoing a hoverboard on October 21, 2015?

next year

I defy anyone to come up with a better marketing campaign than this.

The meat of the story comes from what has until now been a scientific curiosity. Everyone reading this has no doubt seen superconductors levitated off a bed of magnets, and demonstrations of eddy currents are really just something cool you can do with a rare earth magnet and a copper pipe. What [Greg Henderson] and Arx Pax have done is take these phenomena and turned them into a platform for magnetic levitation.

According to the patent, the magnetic levitation system found in the Hendo hoverboard works like this:

  • One or more electric motors spin a series of rotors consisting of an arrangement of strong permanent magnets.
  • The magnets are arranged in a Halbach array that enhances the magnetic field on one side of the array, and cancels it on the other.
  • By placing the rotors over a conductive, non-ferrous surface – a sheet of copper or aluminum, for example – eddy currents are induced in the conductive surface.
  • These eddy currents create a magnetic field that opposes the magnetic field that created it, causing the entire device to levitate.

That’s it. That’s how you create a real, working hoverboard. Arx Pax has also developed a method to control a vehicle equipped with a few of these hover disks; the $900 ‘Whitebox’ technology demonstrator includes a smart phone app as a remote control.

If you’re still sitting in a steaming pile of incredulity concerning this invention, you’re in good company. It’s a fine line between being blinded by brilliance and baffled by bullshit, so we’re leaving this one up to you: build one of these devices, put it up on hackaday.io, and we’ll make it worth your while. We’re giving away some gift cards to the Hackaday store for the first person to build one of these hoverboards, preferably with a cool body kit. The Star Wars landspeeder has already been done, but the snowspeeder hasn’t. Surprise us.

Hackaday Munich Speaker: Sprite_TM

Plans for Hackaday Munich are coming along quite nicely. Today we’re happy to announce that [Sprite_TM] will be speaking at the event. Click that link above and make sure you get your tickets for November 13th. You can do some hands-on hacking at the Embedded Hardware Workshop, hear the talks, find out which of the five finalists will be the grand prize winner, and enjoy The Hackaday Prize Party along with the Hackaday crew.

You may also know [Sprite_TM] as [Jeroen Domburg], one of the judges for The Hackaday Prize. That’s him on the left in the image above (we love a good avatar!). If you follow Hackaday, you should already be thrilled about meeting him and hearing his talk. The last talk we remember reading about was an epic hard drive controller hack. Just last month we saw a well-executed clock radio overhaul from him. While we’re on the topic, his micro-bots were a spectacular project.

[Sprite_TM] has also offered to help out with the reverse engineering workshop. We’re hard at work making sure everything is in place for those afternoon hacking events. As we solidify details we’ll be adding workshop pages (and emailing those already registered for Hackaday Munich) to let everyone know what to expect. We can report that we have shipped [Sprite_TM] a Bus Pirate so that he can be familiar with it. This will be the primary tool provided for this particular workshop.

The entire Hackaday crew is looking forward to it. See you there!

Think Before You Measure – Old Test Gear and Why It Is Awesome

Good, workable test gear is key to enabling our hobby. In this post we will discuss where to procure it at rock-bottom prices, what to look for, how to fix it, and how to tailor your laboratory practices around gear that may not be reliable.

We are lucky to be living in an era with plentiful high-quality test gear. Since the Second World War, surplus test gear has been in abundance at low costs enabling hobbyists, innovators, and academics to experiment and build great things. If you are willing to think before you measure you can save serious amounts of money and have a professional laboratory in your home.

Where to buy
The obvious answer is eBay, but the deals on test equipment are at the hamfests. Don’t be fooled by the name. Hamfests sell much more than amateur radio equipment. Hamfests are swap meets where hobbyists trade electronics of all kinds. Check out the ARRL hamfest calendar to find the next local one near you! I suggest you arrive early, however. The culture of hamfests tends to favor showing up as soon as the doors open and leaving about two hours before the official end. The early bird gets the worm!

Hackaday Munich — Get Your Ticket Now!

If you’re anywhere remotely near Munich in November you’re not going to want to miss this. Hackaday is throwing our first European event! The fun runs from 12:30-23:30 on Thursday, November 13th, 2014.

Take the afternoon off of work

Tell your boss this is professional development, then grab all your hacking gear and head on down to Technikum at the Munich Kultfabrik.

Our set of workshops will test your embedded skills whether you’re a beginner or seasoned veteran. These include controlling small robots, working with audio processing from a Moog synth, reverse engineering some mystery hardware, and trying your hand at machine vision.

Try win the afternoon’s challenges. Implement the fastest and most reliable robot brain, design the best Moog synth add-on circuit. Or prove your logic skills by coding a perfect Computer Vision game solver. We’ll bring some prizes for those that show the most clever and impressive skill.

Take in the talks and learn the winner of The Hackaday Prize

Beginning at 19:00 we present a couple of talks about embedded hardware sure to impress the most discerning of hackers. Immediately following we will announce the Grand Prize winner of the 2014 Hackaday Prize. This Open Hardware build is the project that made it through more than 800 entries to secure a trip into space and eternal recognition from the Hackaday community.

Finish the day with a party

Finally, we’ll dim the lights and turn up the music for The Hackaday Prize Party. Enjoy some food and beverages, get yourself 3D scanned, try your hand at some vintage video games, and enjoy the company of the Hackaday Community. In attendance will be [Mike Szczys], [Brian Benchoff], [Aleksandar Bradic], [Jasmine Brackett], and [Ben Delarre].

We’ll see you there!
