Merry Christmas, Joyous Kwanza, Happy Hanukkah, and (for the pagans) Enjoy the Winter Solstice!  Please enjoy this video from HaHa’s favorite high-voltage Brit, PhotonicInduction!  Enjoy! (And if you haven’t watched PhotonicInduction’s YouTube videos, DO IT NOW! They will change how you view high voltage forever.)

This isn’t a complete list or anything just some links to people’s albums we found. You should check out the entire albums because all the projects are really cool.  Here’s a video of the presentation and here’s some links to pics scoured from the web: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18.  Maximum Tech Photos: 1 2

Brooklyn, NY Here we come! Paul, Jeff, Miles, David (from left to right) will be headed to New York in July to compete against 15 other teams in the Red Bull Creation challenge.  You can read the official e-mail below.

The photo on the left was taken at 3am as we were finishing up our qualifying entry to the Red Bull Creation challenge.
Here is Popular Mechanics coverage of the winners.
Our submission:

Congratulations Harford Hackerspace! Great Joy!

Your team has made it to the final round of Red Bull Creation, and you are invited to come to New York to take part in the ultimate 72 hour build-a-thon!

Go ahead and jump up and down, run around, call everyone you know (most importantly your teammates) and do what you need to do to celebrate, cause you’re invited to take the final challenge! Yes it’s true. You Won.

This is what you gotta do next:

What are we going to do with our newly acquired vintage 1977 Lear Siegler terminal?  Why, we’ll play ASCII Star Wars Episode IV on it, of course!  Recently purchased at the 2011 Techno Swap Fest, this baby-blue beauty has classic 70′s styling, comfortable keyboard and gets 80 columns on the screen in a lovely white uppercase font.  It took some coaxing to get Baby Blue to play along with an Ubuntu-equipped laptop including tweaking some DIP switches hidden inside her chassis, some clever character substitutions in the ASCII Star Wars file, reading the datasheet for the terminal itself (thanks, Wikipedia!), and wiring up both a FTDI USB-to-serial converter and a MAX232 level converter IC.  But the results were worth a quick video.  Future improvements could include a way to hide the cursor (hardware modification?) and possibly speeding up draws by only painting the characters that have changed.  What do ya think?

Like most normal people, I enjoy blinky lights.  Although I helped build the ring of lights in the Tron disc, I was not involved with any of the hardware or software used to actually control the LEDs.  Prior to this project, I had never done anything more than simple PWM control of a few LEDs directly from a micro-controller, so I decided it was a good time to learn how to control a lot of LEDs.  Since this was done for the purpose of learning, I did everything as difficultly as possible, such as building my own LED array on a protoboard instead of just buying an array.  I also wrote code to bit-bang the serial data instead of just using the compiler’s built in SPI function.  But, I wanted a generic serial data module anyway after dealing with the Nokia 6100 and it’s weird 9-bit SPI.  The main point of the whole project was to simply do it myself without asking anyone at the space for help with anything.  I’m sure the code could be a lot better, but it does what it is supposed to do (I think).  :)

Harford Hackerspace took First Place in the first ever Baltimore Hackathon. It took nearly all 48 hours for us to plan and build RotoFoto. RotoFoto is an automated 3D imaging system that takes a series of 2D images of an object and stitches them into a 360 degree interactive image. This allows viewers to use simple mouse dragging gestures to rotate an object to see if from all angles. Watch the complete build in the below time lapse video. We will demonstrate the build shortly so check back soon.

This was a very cool experience for us. We were asked by Gary Mauler to appear on the Fox 45 morning news to promote Electronica Fest. We showed up at the National Electronic Museum at 5:30am to prepare for our 6:10am, 7:10am, and 8:10am live coverage. Unfortunately the segments were very short so we did not get to explain our own projects. However, our Cornstarch Monster project stole the show. See for yourself.

Me and my wife recently had our first child.  I’ve been trying to come up with some projects I can do for the kid.  Well, around this time of the year the fireflies go crazy around my house, so we came up with the idea to do led fireflies in a jar.  It should be something cool for him to stare at and is easy to build.

Schematics, C source code and hex file are available here on our wiki.  If you want to build one it should only take about an hour.

I’m planning on making a version 2 with some changes, stay tuned for that one.

Our first birthday!  Seems just like yesterday, HaHa was just a twinkle in Dave’s eye.  Check out this video of us enjoying some inkjet-printed confection.

This video is in response to the one posted here, where a Mr. Riley Porter moves a 35 pound dumbbell with his CNC.  We decided to try to trump his CNC’s weight-moving ability by pushing our machine to lift and move first 45, then 55 and finally 65 pounds!  We wanted to continue with the weight increases, but did not have a safe way to attach more weight to the Z-axis assembly.  Our CNC build is turning out to be quite the beast.  Now all it needs is a catchy name…
