Find The Giant Jolly Wrencher At Maker Faire This Weekend

scaled_DSC_0038

Check it out, I made something really geeky for Maker Faire. If you’re going to be in San Mateo this weekend for Maker Faire Bay Area, watch for the floating Skull and Wrenches. I won’t be alone, and my compatriots and I will be loaded down with stuff to give away to those who ask for it. If you are hell-bent on finding us, just check this Twitter list as we’ll frequently be tweeting our locations and exploits.

Want to grab a beer with some other Hackaday folk? Even if you’re not attending the Faire, you can take part in the festivities. We’re descending on O’Neil’s Irish Pub on Saturday night. You might want to let us know you’re coming. You can show up unannounced, but we can’t guarantee that you’ll be able to squeeze into the 80-person-pub. If we have way too many hackers overflowing into the street we’ll probably split the party up and go bar hopping. The place is apparently right next to a train stop for your traveling convenience. We just hope to keep things tame enough to make it to Maker Faire again on Sunday morning, but we can’t guarantee that either ;-)

Developed On Hackaday: License Incompatibilities And Project State

mooltipass top pcb

It has been a while since we wrote an article about our ongoing offline password keeper project, aka the Mooltipass. Our last post was asking our dear readers to vote for their favorite card art, so what have we been doing since then?

For the last few weeks we’ve mostly been improving our current PCBs and case design for the production process to go smoothly. The final top PCB shown above has been tweaked to improve his capacitive touch sensing capabilities, you may even see a video of the system in action in the Mooltipass project log on hackaday.io. We’ve also spent some time refining the two most popular card art designs so our manufacturers may print them correctly. We’ll soon integrate our updated USB code (allowing the Mooltipass to be detected as a composite HID keyboard / HID generic) into the main solution which will then allow us to work on the browser plugin.

It’s also interesting to note that we recently decided to stop using the GPL-licensed avrcryptolib. Our current project is CDDL licensed, allowing interested parties to use our code in their own project without forcing them to publish all the remaining code they created. The GPL license enforces the opposite, we therefore picked another AES encryption/decryption implementation. This migration was performed and checked by our dedicated contributor [Miguel] who therefore ran the AES NESSIE / CTR tests and checked their output, in less than a day.

We’re about to ship the first Mooltipass prototypes to our active contributors and advisers. A few weeks later we’ll send an official call for beta testers, just after we shown (here on Hackaday) what the final product looks like. Don’t hesitate to ask any question you may have in the comments section, you can also contact us on the dedicated Mooltipass Google group.

Get Your Uni, School Or College Involved In The Hackaday Prize

We’ve been busy contacting design tech and electrical engineering education departments to tell them about The Hackaday Prize, but there are only so many of us and we could do with your help to get the word out.

Are you excited about The Hackaday Prize? Do you think more people at your school should know about it so they can take part? Either way, please help us help them by emailing prize@hackaday.com to let us know what program coordinators, student group, or other people we should contact. If appropriate, we have a bunch of promotional materials we would like to send out to some of these awesome hackers.

You can also help us by telling your hacker designer friends, posting about The Hackaday Prize on college social media (#HackadayPrize), or letting the student newspaper know. We want to get as many universities, colleges and high schools involved as possible. Many senior year project ideas would make great starting points for THP entries, and we want to make sure students take up this opportunity to show off what they can do (and hopefully win some stuff in the process). This makes a great summer project, and looks great when applying for colleges or jobs in the future.

Remember you have until August to get your entry in, but the sooner you post it on Hackaday Projects, the sooner you can potentially start winning rewards. We have hundreds of tshirts, stickers, patches, posters and other swag up for grabs on the way to winning The Hackaday Prize.

 

Hackaday At Maker Faire

Hackaday Meetup With HeatSync Labs And The Tymkrs

 

hackaday-meetup-tymkrs-hsl

We know a lot of hackers will be heading to Maker Faire next weekend. If you find yourself passing through Mesa, AZ on your way or you’re a local hacker enthusiast then please feel compelled to drop by HeatSync Labs on May 15th between the hours of 5pm and 9pm for an informal gathering. You will get to meet HeatSync Labs hackerspace members and The Tymkrs (Whiskers and Addie) who are founders of The Rabbit Hole hackerspace in Rochester, Minnesota. Sorry for the late notice, I thought it would be a great opportunity to organize an impromptu hacker meetup in order to include The Tymkrs as they pass through town on their epic summer road trip.

If people have a project or photos of a project they’re working on I would enjoy hearing all about it and I’m sure others would as well. I’m looking forward to visiting everyone that can attend!

For those who show up early there should be plenty of pizza, soda and Hackaday swag to go around. I’d like to thank the members of HeatSync Labs for kindly letting me schedule a Hackaday style meetup at their hackerspace on such short notice. There will be some food and drink so don’t be too late or you might go hungry.

Meetup address: HeatSync Labs 140 West Main St. Downtown Mesa, AZ

 

Sci-Fi Contest Winners

We’re happy to announce 16 winners of the Sci-Fi Contest! The Hackaday Crew is thoroughly impressed with pretty much everything that was entered. The 50 projects which were marked as “complete” spanned a wide range of Science Fiction universes, and showed off the talent of the hackers who posted them.

As a quick side note: Some people have confused this contest with The Hackaday Prize. That one is still on, runs into November, and offers a trip into space as the grand prize. Get hacking!

Prizes

all-sci-fi-prizes

We have a range of prizes for the winners. The Grand Prize winning team can choose between two packages, one is anchored by a pair of oscilloscopes (an OWON DS7102 and a Rigol DS1052E), the other swaps out the OWAN for a soldering station and a rework station. Top Prize winners can choose between three packages which offer a rework station, a soldering station, or a collection of dev boards. And finally, the community favorites can choose from several Sci-Fi themed prizes like Blu-Ray, DVD, coasters, toothbrushes, and other kitsch.  For a complete list of the prizes, check out the contest announcement.

Grand Prize: Demolition Man Verbal Morality Statute Monitor

Demolition Man Verbal Morality MonitorThe Verbal Morality Statute Monitor project was an early favorite of ours because the choice of Sci-Fi tech was perfect; a symbolic centerpiece of a dystopian future that can be perfectly replicated with current technology.

[tdicola] and his suspect partner [colabot] moved far beyond that favored status with a solid build that included mechanical design (which was quite a hack), hardware, and software.

The shiny unit hangs on the wall and listens for profanity, sounding an alarm and printing a citation whenever one is detected. We do hope that this ends up in a public space — perhaps a hackerspace full of foul-mouthed members. The delight of the Morality Monitor is that it can generate extra revenue and we suspect offenders will be happy to pay-up… well, maybe at first.

Second Place: Animatronic Iron Man MKIII suit

Animatronic Iron Man SuitThe scope of this project, which is the work of [Jerome Kelty] and [Greg Hatter], is impressive. The full-size Iron Man suit is wearable, true to the look of the film version, and packed full of animatronics. It won’t stop bullets, blow up bad guys, or fly… but it looks as if it can do all of that.

From helmet to boots the exoskeleton is packed with electronics. These are comprised mostly of things that light up, and things that move parts of the suit. But you also need a way to control that functionality and this is one of the most clever aspects of the design.

Each glove has an RFID tag reader in the palm area, with tags on the fingertips of the third and fourth finger. Closing your fingertip to your palm initiates a programmed sequence. All of this is well-documented in the Project Details section, with code and schematics for each subsystem shared as Build Logs.

Third Place: M.A.R.S.

sci-fi-winner-3-MARS-roverThis rover looks like an elegant insect. In a world full of clunky-looking robotics projects that’s high praise. The name of the project is an acronym for the MADspace Advanced Robtics System; a project which, from the start, sought to recreate an Open Design version of the NASA Rovers known as Spirit and Opportunity.

[Guus van der Sluijs], [Paul Wagener], and [Tom Geelen] turned this project into a showcase of what today’s widely available design software and fabrication tools can accomplish. Most of the connecting pieces were 3D printed (check out all of them in the components list), with 10mm aluminum tubing making up the rest of the chassis, and rockers to support the six wheels. Speaking of wheels, check out all the fab work that went into those! And we haven’t even mentioned the hw/sw which drives the thing!

Fourth Place: Back To The Future Time Circuit Clock

sci-fi-winner-4-BttF-ClockThis one has a very visceral hacked feeling which immediately made us take note. When you start to dig into the work which [Atheros] and [bwa] put into the Time Circuit Clock from the movie Back to the Future, the project really stands in a place of its own. Inspiration to build this came from a design which was posted by Hackaday alum [Phil Burgess] over at Adafruit.

The large collection of 14 and 7 segment display modules which make up the three parts of the clock are all hosted on about 23 PCBs which were etched as part of the development process. The electronic assembly is solid, with ribbon cables and modular design to keep it as tidy as possible. The frames for the displays are cut out of wood and the entire thing is controlled from a keypad. The clock, alarm, and FM radio make this a perfect bedside device — if you can abide being blasted by three colors of LED displays as you try to sleep.

Fifth Place: Marauder’s Map

sci-fi-winner-5-Marauders-MapThis one is hard to sum up with a single image, because The Marauder’s Map uses radio frequency communication to track beacon locations of boards like the one pictured here. Well, they tried to use this custom hardware but were unable to work out all the bugs and ended up showing the proof of concept using some EZ430-RF2500 dev boards.

We’re certainly not holding that against [phreaknik] and [ wahwahweewahh]. The amount of software that went into the mapping system is arguably more impressive than a bug-free prototype board would have been. The system can take the dimensions for any room, as well as locations of the base stations. It then polls the base stations to triangulate relative position of the beacons with great accuracy.
We have confidence that the custom boards will work at some point (this would actually make a great entry for The Hackaday Prize, right?).

Honorable Mentions

Glasses block light when they sense dangerIt was heartbreaking that these Peril-Sensitive Sunglasses didn’t make it into the top five. This, and the five projects above, were all in a tight race for the prizes. Since this project isn’t going to make the list of Skulled or Followed projects we’ve decided to award it one of those prize packages anyway in recognition of the wonderful work [Minimum Effective Dose] and his AI partner [Colabot] pulled off. The project is, of course, based on [Douglas Adams’] Hitchhiker’s Guide to the Galaxy tech which allows the wearer to avoid getting upset in times of peril. The shutter glasses originally meant for 3D television viewing have been modified to sense danger and block the wear’s view of it.

The rest of the Honorable Mentions are awarded the honor of being mentioned (in alphabetical order):

Community Favorites

There are also prizes for the most Skulled and most Followed projects. Here are those winners in rank order. This list was a snapshot from Wednesday, May 7th, and since Hackaday.io is a living site the totals will change over time. The five top winners are excluded from these prizes; Skulled winners cannot also win for Followers:

Ask Hackaday: Can The Lix 3D Printing Pen Actually Work?

Introducing Lix, the world’s smallest 3D printing pen that allows you to draw plastic structures in 3D. It’s only been on Kickstarter for a few days now, and already it has garnered close to a million dollars in pledges. An astonishing achievement, especially considering we can prove – with math and physics – that it doesn’t work as advertised. However, we’re wondering if it could work at all, so we’re asking the Hackaday community.

The device is powered through a USB 3 port. In the video, the Lix team is using a MacBook Pro. This has a USB port capable of delivering 900 mA at 5 Volts, or 4.5 Watts. Another 3D printing pen, the 3Doodler, uses a 2A, 12V power adapter, equal to 24 Watts. Considering the 3Doodler works, and they both do the same basic thing, there’s something extremely odd going on here.

Just as a comparison, here’s a wirewound resistor commonly found in the heating element or ‘hot end’ of a 3D printer. It’s a 6.8  Ohm resistor powered at 12 Volts. That’s 21 Watts. Here’s a heater cartridge, also found in quite a few hot ends. It sucks down 40 Watts. Once again, the Lix Kickstarter clearly shows the pen extruding filament using only 4.5 Watts of power. Something is really, really fishy here.

Intuition doesn’t hold a candle to math, so let’s figure out exactly why it won’t work.
