MakerFaire North Carolina, We’ll See You There!

June 14, 2012 by Caleb Kraft 1 Comment

This weekend, June 16th, the North Carolina Maker Faire will be happening. This is the 3rd year for this event and from what we’ve seen in the past, it should be pretty good.

We realize that every site has its niche of event coverage that they should deliver. Engadget/Gizmodo need to show new phones and got to big apple announcements. Joystiq needs to be at E3. We feel like we should be where people are hacking/building things. In an effort to reach those places, Maker Faire pops into mind pretty quickly. [Jeremy Cook] will be at this one walking around and doing interviews as well as having a booth for his personal site jcopro.net . If you see him, don’t hesitate to go up and say hi, maybe he’ll have a custom cut vinyl hackaday sticker left to give out.

We plan on hitting as many other similar events as we can swing (sorry, looks like no one can make it to toorcamp this year). Our writers are located all over the country so if you hear of an event you think we would enjoy, shoot us an email. Maybe we can attend!

Toorcamp Is Coming!

June 13, 2012 by Caleb Kraft 12 Comments

Hey, I like a good party like anyone else. I’ve been drooling over some of the projects coming out of burning man for years. However, the ratio of “gettin’ crazy” to “build awesome stuff” seems to be slanted in favor of the party experience. There’s absolutely nothing wrong with that. However, when I saw this, my eyes welled up with tears of joy.

ToorCamp is Burning Man with less drugs and more hacking. This summer ToorCamp will take place on the northwest corner of the staggeringly beautiful Olympic Peninsula. Just get yourself out there!

Located at the Hobuck beach resort near Neah Bay WA, Toorcamp is a 4 day event that should pull in roughly 1,000 enthusiastic hackers. There are four “villages” that you can wander through; the lock picking village, the hardware hackers village, the maker’s village, and the crafting village. All should include bountiful talks and hands on workshops. There’s also a quiet camp if you really really want to avoid the inevitable sporadic parties.

LayerOne Badge Hacking Twofer

May 31, 2012 by Mike Szczys 2 Comments

Here’s a pair of LayerOne Badge hacks that actually included the RC as intended by the badge designers.

First up, we have the autonomous RC car built by [Arko]. He calls it Stanley Jr. as an homage to the Stanford DARPA Grand Challenge vehicle. It uses an Arduino shield to add a servo with an ultrasonic rangefinder on it. The lets the vehicle drive a bit, stop and scan the horizon, then drive some more. The hope is the rangefinder will keep it from running into anything. There’s a quick test run embedded after the break.

On the right is the badge hack which [Zjpahle] finished up after the contest was already over. He also chose to go with an Arduino shield, this time it’s an IMU board. But he added a standalone Arduino board to the vehicle which drives some EL wire (ground effects) and adds IR sensors to the front of the car. The IR sensors are for obstacle avoidance, and the IMU lets him tilt his badge for direction control.

We looked at the winner of the badge hacking competition on Wednesday. That hack didn’t involve the car, but used the badge as a Morse Code beacon.

Morse Code Beacon Wins The LayerOne Badge Hacking Contest

May 30, 2012 by Mike Szczys 2 Comments

Ham skills prevail in this year’s LayerOne badge hacking contest. [Jason] was the winner with this Morse Code beacon hack.He got a head start on the competition after seeing our preview feature on the badge hardware development. It got him thinking and let him gather his tools ahead of arrival.

The hardware is segregated into two parts of the board. The lower portion is a take on the Arduino, and the upper portion is a wireless transmitter meant to control some cheap RC cars. [Jason] figured this was perfect for conversion as a CW beacon (continuous wave is what Morse Code is called if you’re a ham). The first issue he encountered was getting the badge to play nicely with the Arduino IDE. It was setup to run Slowduino firmware which uses the internal oscillator. [Jason] soldered on his own crystal and reflashed the firmware. He found that the transmitter couldn’t be directly keyed because of the shifting used in the RC car protocol. He cut the power to the transmitter, and found that it could be more accurately keyed by injecting power to one of the other pins. Check out the video after the break for a better explanation of his technique.

LayerOne Badges Stop Bullets; Drive Away

May 24, 2012 by Mike Szczys 13 Comments

We love badges. And we’ve really got to thank [Charliex] for taking the time to write a huge post about this year’s LayerOne badges, especially since they’ve got their backs up against the deadline for pulling everything together in time.

Here it is, the stock badge on the left, with an add-on shield on the right. Now the original intent was to make this badge the chassis of an RC car. [Charliex] chewed through his development time trying to source toy cars that could be gutted for parts that would mount easily on the badge. This looked promising at first, but turned out to be folly. Instead what we have here is an Arduino compatible board with an RF transmitter which can be cut off and used separately if you wish. Attendees will be able to use the badge to take control of the toy cars (cases of them have been shipped to the conference), with the option to use the USB functionality to facilitate automation.

So what about stopping bullets? There is a bug in the module [Charliex] used to export the board design from Eagle. They came back from the fab house as 0.125″ substrate. That’s pretty beefy!

The conference is this weekend… better get on that!

Build Your Own Radar System

April 28, 2012 by Mike Szczys 23 Comments

How we missed this one is anybody’s guess, but one of the presentations at DEFCON last year covers a DIY radar build. [Michael Scarito] talks about the concepts behind radar, and then goes on to show that it’s not too hard or expensive to build a setup of your own. We’ve embedded his 45 minute talk after the break.

The two large pieces of hardware above should look familiar. They’re descendents of a favorite hacking project, the cantenna. The can-based long-range antenna is most popular with WiFi applications, but we’ve seen it used for Bluetooth as well and it’s not surprising to see it here. The rest is a lot of sensing hardware and enough math crammed into the coding to make your ears droop.

If you make it far enough (exactly 39 minutes into the talk) [Michael] shares some links for more information on the build. We think living vicariously is enough for us, but if you manage to build your own setup don’t forget to post a project log!

Time To Get Serious About Going To LayerOne

April 26, 2012 by Mike Szczys 2 Comments

This year’s LayerOne Hacking and Security Conference is right around the corner. But it’s not too late to attend. You can still get a block-rate hotel room if you register by the end of April, and registration for the two-day event only costs a hundred bucks. It’s scheduled for May 26th and 27th in Anaheim California.

As usual, the Speaker lineup is quite impressive. Everything from Android Malware to embedded exploits and botnet adventures will be discussed. And then there’s the perennial favorite lock picking and hardware hacking villages. Did we mention badges? We’d bet it was this pick-and-place machine which helped assemble this year’s pile of badges. We haven’t seen any word on what they might include, but there’s a hacking contest so plan to pack your tools.
