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.

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.

HaHa member bsom acquired a Robonova-1 bi-ped robot kit for his day job and brought it to the space for us to assemble, configure and generally play with.  So far, the robot is about 85% done, requiring its wires to be properly tucked and its motors to be centered.  Then we can dig in and learn some hardcore RoboBasic.   Videos of the finished bot will be posted once he is up and running.

A while ago, HaHa member bsom introduced us to non-Newtonian fluids and the idea of using cornstarch and water in conjunction with a speaker/amp and function generator to produce what he called a “Cornstarch Monster.”  The video below is an excellent representation of what can be done with this simple yet captivating recipe.

Also, keep an eye on our new YouTube Channel, available here, for more videos, tutorials and technology dissections.

Tonight our CNC showed signs of life. We attached a pen and drew images of circuits, skulls, and Road Runner. The CNC Router was the first project we started working on and it has taken many nights of team work to get to this point. There is still a lot more to do. We started working on the Z-Axis tonight and once that is finished we will have to take most of the machine apart and make fine adjustments to make it as precise as possible. After that there is the long process of mastering the 3D Software.

The awsome guys from the Two Hands Projects unexpectedly dropped into Harford Hackerspace last night. The organizer, Bilal, was full of energy and really pumped everyone up. You’ll have to wait for the video to see what happened. Hopefully we will make the cut. In a nutshell they interviewed us and we showed off our space and our projects. Here are a few photos of them getting ready to record.
