Betascape was this previous weekend and Harford Hackerspace was on hand with robots, lightning bug jars, and general awesomeness. We setup early Saturday morning between Baltimore Node and the First Lego League representatives. The day was spent forging various cardboard blades with crayons and stickers with various children blacksmiths quietly honing their craft. All in all we gave away approximately 50 swords to young lads and lasses who,  no doubt, brought these mighty cardboard weapons to bear against a variety of fiends.

The previously mentioned Baltimore Node was there demonstrating various projects such as air powered rockets and some sort of power tool drag racing. Set up across from us was The Digital Media Center from Johns Hopkins  demonstrating cloth circuitry and teaching others about cloth circuits. The National Electronics Museum was setup in the back with some kind of robot (which I did not see). Various other people included a company demonstrating a 3D picture taking technology, Bryan Dolge with a makerbot, as well of a bunch of gamemakers in the game making section.

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.

Robot Fest 2010 has come and gone. Some of the many interesting exhibits this year included the pneumatic rocket experience provided by the Baltimore Node, the many Lego Mindstorms projects, Maker Bot demonstrations, various art demonstrations, and a fashion show.

Make coverage and more pics here.

We’d like to thank everyone that stopped by our exhibit to view the Oobleck demonstration, PIC micro-controller LED arrays, the hand-powered Arduino random movie quote generator, build some cardboard robots, or just hang out and talk electronics. We had a great time and we hope to see everyone next year. Our next event will be at ArtScape in Baltimore. In the meantime, feel free to come by and do some hacking on one of our open hack nights.

Congratulations Eileen Barnett!

Eileen is the winner of Harford Hackerspace’s first ever raffle and she is the proud new owner of an iRobot Roomba. She also received Hacking Roomba book.

When we first contacted Eileen she thought we were pulling her leg. Once she overcame the initial shock and realized she had actually won, Eileen got even more excited.

We would like to send a special thanks to everyone who supported Harford Hackerspace by purchasing a raffle ticket and visiting us at RobotFest 2010 for the drawing.

We just posted a new tutorial called Programming PIC Microcontrollers with C. It’s designed to get you started programming using MPLAB and CCS C Compiler. The only hardware you need to get started is the PicKit2 or PicKit3 which comes with a demo board. The demo board contains 8 LEDs, 1 Potentiometer, and a Pushbutton all wired and ready to go.

Check it out Here!

Harford Hackerspace is pleased to announce that we have received our official letter of approval from the Internal Revenue Service giving us 501(c)(3) non-profit, charitable status.

We started our adventure of becoming a charitable organization in July 2009 with the help of Nick Farr from HacDC. Nick took time out of his busy schedule to visit our Hackerspace and go through the rough draft of our IRS Form 1023. Without him we would have made a few mistakes on our form. A very special thanks goes out to you Nick.

In October 2009 we put the stamp on our envelope and sent our application to the IRS hoping for the best. A lot of hard work went into preparing the application. It’s a 26 page application and several of the questions require written responses. To keep the application reviewer from guessing at what we do we included several project examples and  took photos of us working as a group.

On January 11th 2010 we got a request for more information. Apparently this is standard procedure for all applicants. The questions were fairly straight forward and we were able to call the IRS agent directly and ask her questions. After faxing her our answers the lady quickly reviewed them and told us over the phone that she was recommending us for our 501(c)(3) status.

Today, we finally received our approval letter complete with our 501(c)(3) exemption number. It has been a long time coming but I am sure all the hard work will pay off in the near future.

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…

The CNC machine’s construction has advanced to the point where we can begin to cut items.  Being a bunch of teenagers trapped in adult bodies, someone decided that we should cut a throwing star from sheet aluminum.  One copy of CamBam and 6 minutes later and the star was ready to be cut!  After a few adjustments and a bit snapped in half from being dragged through the metal too fast, the cutting was underway.  The star took about 10 minutes to cut and was an excellent first attempt at metal production.  The next step is to use the CNC to cut more precise parts for itself and help bring about the Robot Armageddon.   Special thanks to our newest sponsor, CamBam, for supplying us with a free copy of their most excellent software.  Note: The soundtrack to this video may change at any time as we are experimenting with YouTube’s AudioSwap feature.

Very quick video documenting our Robonova’s first steps, warts and all…  A bit rough since he has yet to be properly calibrated or balanced and his battery pack is still hanging off of his back.
