HOPE X is happening. There are tons of people here. Tons. So many that people (including me) have been turned away at the door for popular talks. Overall, we are having a great time and meeting some interesting people.

I admit to having zero lock picking experience. It’s something I’ve thought would be neat to learn about for a long time. Well, today was the day…. I attended the “Lockpicking, A Primer” presentation and it was great. They started with the basics, discussing the appeal of lock picking and where organized Lock Sport started. The presentation consisted of excellent graphics and clear explanations of the lock picking process. They went over the anatomy of a lock and how they work as well as the tools used and tool types. The talk also progressed into more advanced topics. There is even a lock picking village where you give it a go. I’ll be trying it out for sure.

Couldn’t make it to NYC for the event? All of the talks are streamed live. You’ve probably heard that Hackaday has a booth at HOPE this year. Swing by and say hi. You could probably convince us to give you a shirt!

We’re At HOPE X

July 18, 2014 by Brian Benchoff 5 Comments

For the next three days, Hackaday will be live, in the flesh, at Hotel Pennsylvania in NYC. It’s HOPE X, the biennial conference for hackers, code crackers, and slackers put on by the awesome folks at 2600.

Highlights of the event include a keynote from [Daniel Ellisburg], a video conference with [Edward Snowden], and a whole bunch of other stuff. Hackaday has a booth (thanks, overlords!) on the mezzanine right with the other vendors, right behind the Club-Mate table.

We’ll be putting up random updates from HOPE the entire weekend. If you’re visiting, stop by and we might have a t-shirt for you.

Backyard Brains: Controlling Cockroaches, Fruit Flys, And People

July 18, 2014 by Brian Benchoff 16 Comments

[Greg Gage] and some of the other crew at Backyard Brains have done a TED talk, had a few successful Kickstarters, and most surprisingly given that pedigree, are actually doing something interesting, fun, and educational. They’re bringing neuroscience to everyone with a series of projects and kits that mutilate cockroaches and send PETA into a tizzy.

[Greg] demonstrated some of his highly modified cockroaches by putting a small Bluetooth backpack on one. The roach had previously been ‘prepared’ by attaching small electrodes to each of its two front antennas. The backpack sends a small electrical signal to the antennae every time I swiped the screen of an iPhone. The roach thinks it’s hitting a wall and turns in the direction I’m swiping, turning it into a roboroach. We seen something like this before but it never gets old.

Far from being your one stop shop for cockroach torture devices, Backyard Brains also has a fairly impressive lab in the basement of their building filled with grad students and genetically modified organisms. [Cort Thompson] is working with fruit flies genetically modified so a neuron will activate when they’re exposed to a specific pulse of light. It’s called optogenetics, and [Cort] has a few of these guys who have an ‘I’m tasting something sweet’ neuron activated when exposed to a pulse of red light.

Of course controlling cockroaches is one thing, and genetically engineering fruit flies is a little more impressive. How about controlling other people? After being hooked up to an EMG box to turn muscle actuation in my arm into static on a speaker, [Greg] asked for a volunteer. [Jason Kridner], the guy behind the BeagleBone, was tagging along with us, and stepped up to have two electrodes attached to his ulnar nerve. With a little bit of circuitry that is available in the Backyard Brains store, I was able to control [Jason]’s wrist with my mind. Extraordinarily cool stuff.

There was far too much awesome stuff at Backyard Brains for a video of reasonable length. Not shown includes projects with scorpions, and an improved version of the roboroach that gives a roach a little bit of encouragement to move forward. We’ll put up a ‘cutting room floor’ video of that a bit later.

Marvin’s Marvelous Mechanical Museum

July 17, 2014 by Mike Szczys 9 Comments

Don’t call it an arcade. There are arcade-like things about it… like dance-based video games, Skee-ball, and tickets — oh so many tickets. But Marvin’s Marvelous Mechanical Museum is a one-of-a-kind that you need to visit next time you’re in the North suburbs of Detroit, Michigan.

[Marvin] was there in person, as he is many days. He talked with us for a few minutes and we’ve folded his interview, along with footage of many of the attractions, into the video above.

He’s been collecting for more than three decades. The attractions are packed into every bit of floor space, spilling up onto the walls, and hanging from every spot in the ceiling. There are true antiques from both home and abroad that could be referred to as automatons, rows of fortune tellers, a track of large airplane models that make a loop around the establishment when fed a quarter, and much more.

Some of the attractions were build for him, like the robot band you can make out behind [Marvin] during the interview. It is a MIDI-based build that allows songs to be selected from a touchscreen. Soon to be on exhibit is a Tesla-coil-based offering which [Marvin] commissioned after taking second place to [Nicolai Tesla] on a list of oddest museums.

Red Bull Creation: A Giant Daisy Wheel Printer

July 17, 2014 by Brian Benchoff 17 Comments

While most of the teams in this year’s Red Bull Creation didn’t really pay attention to the theme of ‘reinventing the wheel’, 1.21 Jiggawatts did. Their creation, a giant typewriter that can be suspended along the side of a building, takes its inspiration directly from 1970s typewriters and printers. Yes, it’s a giant daisy wheel typewriter.

The basic idea of a daisy wheel typewriter is a wheel with a few dozen petals, on the end of which is a single letter. To print a letter, the wheel spins around, and a solenoid mechanism strikes the letter against a piece of paper. This was cutting edge tech in the 70s, and was a fast (and cheap) way for computers to print out letter-quality reports.

1.21 Jiggawatts used a ladder as the rail to move down a line of text. The movement from line to line was supposed to be done by dangling the ladder off a chain with a few sprockets attached to motors. Unfortunately, the team couldn’t quite get the machine working for the competition and live event, but the build does show an amazing amount of creativity and respect for classic, forgotten technology.

The Party Was Bumping, Then The Fire Dragon Showed Up

July 16, 2014 by Mike Szczys 9 Comments

Epic Party.

I don’t use that label lightly. After the Red Bull Creation’s day of show and tell was over — winners having been presented with trophies and stuffed with barbecue over at Bert’s — people started to trickle into OmniCorp Detroit for the party.

Like all of the best parties we didn’t really see it coming. I grabbed a folding chair on the street out front with a beer in my hand and enjoyed a rotating variety of interesting people to talk with. [Brian] rolled up riding one of the trophies, a modified toddler’s tricycle that proves his future with a travelling circuit is still viable. They roped off the area and set up huge speakers for the DJ. Then two guys game lumbering down the street sharing the work of hauling a tub full of ice and 12-ounce clear glass bottles with colored liquid inside. Turns out they just opened a distillery down the street and decided to donate some vodka infusions for the festivities. Yum!

Upstairs, a couple hundred square feet of area was ringed by a bar (with wide variety of kegs, slushy drinks, and one of those hot dog rollers), couches, a few work benches, a second DJ booth, and a photobooth. We only got one picture before the smoke machine reduced visibility.

Unlike a lot of ragers I’ve been at, it was easy to start up a conversation with just about anyone. Living expenses are so low in Detroit and artists are flocking to the area. This is who made up most of the group. Fascinating people who are working on a multitude of different projects and have stories of building community on their streets while rehabbing houses that cost $1-2.5k to purchase but didn’t come with most of what you’d assume a house should.

Then the fire dragon showed up

Inside was packed and outside was starting to get crowded. Then the fire dragon showed up. Named Gon KiRin, it’s the collaboration between [Teddy Lo] and [Ryan C. Doyle] who was on Team Detroitus and is artist in residence at Recycle Here!, the build venue for the Red Bull Creation. The beast is built on the frame of a 1960’s dump truck and most of the building materials were found on the sides of the highway. The huge propane tank on the back allows it to breathe fire. I love that three daisy-chained 9-volts and two bare wires are the control mechanism for this. One thing became readily apparent; you don’t stand in front of Gon KiRin while it’s breathing fire.

The crowd piled onto the couches on top of the tail and at either rear hip. The dragons back also bore a continually rotating set of people. After midnight the guests really started to flood in. [Caleb] and I tried to close down the party but a few hours after midnight it didn’t seem to be getting any slower.

Capping off the weekend like this really proves that you need to get your team into next year’s Red Bull Creation. I got in the easy way — judges don’t have to stay up for 72 hours building stuff. Despite the sleep deprivation for contestants I didn’t come across anyone who wasn’t having a blast during the build, while goofing off, or trying to stay awake as this party got moving.

Bravo Detroit, you’re now on my short list of best party towns. Who else wants to be added to that list? Hackaday’s going to be in Las Vegas for DEFCON in a few weeks. Anyone know of parties planned that weekend and how we can get in?

Kumo Connect: From Automated Desktop And Backyard Gardens To Automated Everything

July 16, 2014 by Kristina Panos 8 Comments

photo hut I ran into a guy at Maker Faire Kansas City who I used to scoop ice cream with twenty years ago. We were slinging frozen dairy at a Baskin Robbins in a dying suburban strip mall that had a one-hour photo booth in the parking lot. It was just far enough away from our doorstep that dotting its backside with the hard-frozen ice cream balls that had been scooped and then not always accidentally dropped into the depths of the freezer was challenging. This guy, [Blake], kept a hockey stick hidden in the back room especially for this purpose. I never could get them to fly that far, but he was pretty good at it.

I hadn’t seen him since those days, and there he was manning a booth at Maker Faire. He looked quite professional, showing no hint of the mischief from those days of ice cream hockey. His booth’s main attraction was Niwa, a connected indoor garden. Having spent four years living and working in Japan after college, [Blake] did not choose this name arbitrarily: ‘niwa’ is Japanese for ‘garden’. He loves Hackaday and was more than happy to share his story.

Connecting with Nature

[Blake] is an avid gardener, but his wife does not share this passion. A few years ago, he took a new job that required travel on an almost weekly basis, which meant big trouble for his plants. Unfortunately, he couldn’t find what he wanted to ensure they were taken care of. You know what comes next: he decided he would design his own system. However, he had no experience with electronics.
