Hackaday Links: August 30, 2015

A month ago, we ran a post about [Jim]’s rare and strange transparent microchips. He’s back at it again, this time taking a look at the inner workings of MOSFETs

The Unallocated Space hackerspace is moving, and they’re looking for a few donations to get the ball rolling.

Yes, it’s a Kickstarter for a 3D printer, but the LumiPocket is interesting, even if only on the basis of the engineering choices. It’s a UV laser resin printer, and they’re using a SCARA arm to move the laser around. They’re also doing a top-down resin tank; it requires more resin, but it seems to work well enough.

Around DC or northern Virginia? We’re going to be there on September 11th through the 13th. We’re holding a Hackaday Prize Worldwide meetup at Nova Labs in Reston, Virgina. Sign up now! Learn KiCAD with [Anool]! Meet [Sudo Bob]! It’ll be a blast.

Not around DC or NOVA? This Wednesday we’ll be hosting another chat on .io.

The GEnx is one of the most beautiful and advanced engines in the world, and that means [Harcoreta] oven on the RC groups forums has made one of the most beautiful electric ducted fans in the world. On the outside, it looks like a GEnx, including reverse thrust capabilities, but inside it’s pure electronics: a brushless motor rotates a 100mm, 18-blade fan. He’s hoping to mount it on a Bixler (!). We can’t wait for the video of the maiden.

Closing out DEF CON 23

We had a wild time at DEF CON last week. Here’s a look back on everything that happened.

defcon-23-hackday-breakfast-thumbFor us, the festivities closed out with a Hackaday Breakfast Meetup on Sunday morning. Usually we’d find a bar and have people congregate in the evening but there are so many parties at this conference (official and unofficial) that we didn’t want people to have to choose between them. Instead, we made people shake off the hangover and get out of bed in time for the 10:30am event.

We had a great group show up and many of them brought hardware with them. [TrueControl] spilled all the beans about the hardware and software design of this year’s Whiskey Pirate badge. This was by far my favorite unofficial badge of the conference… I made a post covering all the badges I could find over the weekend.

We had about thirty people roll through and many of them stayed for two hours. A big thanks to Supplyframe, Hackaday’s parent company, for picking up the breakfast check and for making trips like this possible for the Hackaday crew.

Hat Hacking

For DEF CON 22 I built a hat that scrolls messages and also serves as a simple WiFi-based crypto game. Log onto the access point and try to load any webpage and you’ll be greeted with the scoreboard shown above. Crack any of the hashes and you can log into the hat, put your name on the scoreboard, and make the hat say anything you want.

Last year only one person hacked the hat, this year there were 7 names on the scoreboard for a total of 22 cracked hashes. Nice work!

  • erich_jjyaco_cpp    16 Accounts
  • UniversityOfAriz     1 Account
  • @badgerops             1 Account
  • conorpp_VT             1 Account
  • C0D3X Pwnd you    1 Account
  • D0ubleN                   1 Account
  • erichahn525_VTe     1 Account

Three of these hackers talked to me, the other four were covert about their hat hacking. The top scorer used a shell script to automate logging-in with the cracked passwords and putting his name on the scoreboard.

I’d really like to change it up next year. Perhaps three hats worn by three people who involves some type of 3-part key to add different challenges to this. If you have any ideas I’d love to hear them below, or as comments on the project page.

[Eric Evenchick] on socketCAN

eric-evenchick-socketCAN-defcon-23-croppedOne of the “village” talks that I really enjoyed was from [Eric Evenchick]. He’s been a writer here for a few years, but his serious engineering life is gobbling up more and more of his time — good for him!

You probably remember the CANtact tool he built to bring car hacking into Open Source. Since then he’s been all over the place giving talks about it. This includes Blackhat Asia earlier in the year (here are the slides), and a talk at BlackHat a few days before DEF CON.

This village talk wasn’t the same as those, instead he focused on showing what socketCAN is capable of and how you might use it in your own hacking. This is an open source software suite that is in the Linux repos. It provides a range of tools that let you listen in on CAN packets, record them, and send them out to your own car. It was great to hear [Eric] rattle off examples of when each would be useful.

Our Posts from DEF CON 23

If you missed any of them, here’s our coverage from the conference. We had a blast and are looking forward to seeing everyone there next year!

Help Decipher the DEFCON Badge

The 23rd DEFCON — the Western Hemisphere’s largest hacker conference — doesn’t start until tomorrow but Thursday has become the de facto start for regulars. [Brian] and I rolled into town this afternoon and are working on gathering as much information as possible about the badge challenge.

This year the badge is a 7″ vinyl record. Traditionally the badge alternates years of electronic badges and ones that aren’t. Spend your weekend pulling your hair our trying to solve the puzzles. Check out all the pictures and information (updated as we gather it) and work together collaboratively for a solution by requesting to join the crew on the Badge Hacking page.

Hackaday Breakfast on Sunday

Iocn of Coffee CupIf you’re in town Sunday morning, come nurse your hangover with [Brian], [Eric], and me. We’re headed to Va Bene Caffè at 10:30am on 8/9/15. It’s just across the street in the Cosmopolitan. Request to join this event and I’ll send you a reminder so you don’t forget. You can also hit me up on Twitter for a reminder. See you then (and don’t forget to bring hardware to show off if you have some!).

PS- The Hackaday WiFi Hat is in play. Anyone have the chops to hack it this year?

Meetup in Boston this Thursday

Hackaday is headed to Boston this week. Meet up with us on Thursday at 6pm to show off your projects and meet other hackers in the area. Admission is free, just tell us you’re coming.

We’re hosting a Hackaday meetup at Artisan’s Asylum hackerspace. That name should sound familiar. This is the group that decided to throw down the robot gauntlet with Japan. We can’t wait to see what that’s all about first hand!

While in town we’ll also be stopping by the MIT Media Lab, a legendary den of cutting edge research that springs forth wave after wave of awesome inspiration. If you know of any projects going on there that we just shouldn’t miss please let us know below. We’re also looking for suggestions of other places we should check out while in town.

See you Thursday!

Hackaday Prize Worldwide : Maker’s Asylum New Delhi

Join me on July 18th for Hackaday Prize Worldwide: New Delhi — a KiCad workshop, hardware show & tell, and a chance for you to meet other hackers and makers in the area.

Hacker spaces are on the rise in India, a development that really excites me. When I helped co-found India’s first, community Hacker Space – Maker’s Asylum – in Mumbai, things were pretty lonely. And this was less than 2 years back in 2013 November. Last month, we opened New Delhi’s latest, and the Maker’s Asylum’s second space. There’s already a couple of other hacker spaces in New Delhi, and you can now find hacker spaces in Mumbai, New Delhi, Pune, Bangalore, Chennai, Cochin, Meerut, Kolkatta, Surat, Ahmedabad, Dharamsala, Hyderabad, Ramachandrapuram – and the list continues to grow.

To help build the community, and to bring the opportunity presented by the Hackaday Prize to local hackers, I hosted Hackaday Prize Worldwide events at the Maker’s Asylum in Mumbai and at Workbench Projects in Bangalore. This month, on July 18th, I’ll do another Hackaday Prize Worldwide event at the Maker’s Asylum in New Delhi. I love talking about, and supporting, Open Source Hardware at every opportunity. So for this event, I’ll be doing a fairly long and detailed workshop on KiCad – the awesome, open source EDA tool – lasting several hours. At the end of the day long workshop, I hope to get fellow hackers to complete a design that can be sent off for PCB fabrication. After a short break in the evening, we will have a Show-n-Tell, getting the assembled folks to show off the projects they are working on. There are a number of them who have submitted entires for the Hackaday Prize, so it will be interesting to hear them talk about their experience and share tips and ideas.

We can hold only a limited number of folks at the event, and slots are quickly filling up. So, if you’re in New Delhi or somewhere close by, do RSVP at this link quickly. Looking forward to an interesting event. Check out some pictures from the opening party of the New Delhi Maker’s Asylum after the break.

The Spirit of Hackaday Shines in Shenzhen

Hackaday loves to spread the message of the hardware hacking lifestyle. That’s only possible where there are hardware hackers willing to spend their time getting together to talk the future of the hardware industry, and to celebrate where we are now. We’re honored that you came out en masse for our Shenzhen Workshop and Meetup!

Zero to Product

[Matt Berggren] has presented his Zero to Product  workshop a few times now as part of our Hackaday Prize Worldwide series. This spring that included Los Angeles, San Francisco, and ten days ago it was Shezhen, China.

We partnered with MakerCamp, a week-long initiative that pulled in people from all over China to build a Makerspace inside of a shipping container. Successful in their work, the program then hosted workshops. The one caveat, Shenzhen in June is a hot and sticky affair. Luckly our friends at Seeed Studio were kind enough to open their climate-controlled doors to us. The day-long workshop explored circuit board design, using Cadsoft Eagle as the EDA software to lay out a development board for the popular ESP8266 module.

Come to our Shenzhen Meetup and Tell Your Friends

This Saturday we’ll be in Shenzhen hosting a meetup at Bionic Brew at 19:00. Join us there and bring along your own hardware projects to show around. Everyone loves hearing about that latest build!

Even if you’re not in the area you can help us out by spreading the word. Tell your friends, share on your social media, and let us know about anyone in town who you think we should reach out to. Here’ s a poster if you want to print it out and hang it at your hackerspace, workplace, or other area where awesome people congregate.

The things you can do at this meetup: Laugh, drink, eat, and be happy. Talk excitedly about datasheets and timing diagrams. Pretend you hate talking about timing diagrams while being secretly giddy that someone wants to hear what you think of them. Recount your epic battles to meet production deadlines. Show off that latest blinky LED project you just got working. Meet a ton of awesome people. You can RSVP here to tell us you’re coming. See you soon!
