NEW! PIC C Programming Tutorial Posted

by Squintz on Feb.21, 2010, under How-Tos, Soup

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!

We got our 501(c)(3) status!

by Squintz on Feb.15, 2010, under Infrastructure, Soup

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.

Talking Dirty to MicroControllers!

by solovus on Feb.07, 2010, under Projects

Wednesday was the day we finally got together and started the tedious process of mastering microcontrollers.  What began with just some simple LED illumination evolved and progressed throughout the evening.  In the end we had individually, but collectively, written programs for interpreting analog inputs, displaying binary values, and performing counting and reset operations.  The evening was pretty fulfilling for some less experienced members and refreshing for the remainder.  Another microcontroller experiementation session is being planned for 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.

Our CNC Can Kick Your CNC’s Butt!

by bsom on Dec.06, 2009, under CNC, Projects, Soup, Videos

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…

Our CNC Machine’s First Cuts

by bsom on Dec.04, 2009, under CNC, Projects, Soup, Videos

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.

Robonova-1′s First Steps

by bsom on Dec.03, 2009, under Projects, Soup, Videos

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.

Robonova-1 Construction

by bsom on Nov.24, 2009, under Projects, Soup

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.

Cornstarch Monster Video

by bsom on Nov.22, 2009, under Projects, Soup, Videos

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.
