Drawdio at Sabot

April 29, 2011

Several month’s ago,

hack.rva held a weekly, month long, class on the drawdio. This class was taught to three middle school students at Sabot School in Stony Point. During the class, basics of soldering and electrical circuits were taught while also slowly assembling the drawdio circuit. At the end of the class, the students made a movie teaching what they learned and showing off a little bit. These wonderful kids are proof that nobody should be scared of electronics–a healthy dose of science is good for ya!

RedBull Creation

March 25, 2011

At last night’s weekly hack.rva meeting things were progressing as usual. There were some folks in the workroom, soldering irons in hand putting the final touches on their SpokePOV kits in preparation for the class coming up. Other people were in the conference room checking out some new hardware a member brought in. Out of nowhere the call came. “Hey everyone? You might wanna come in here. There’s something cool about to happen.” At a place like the hackspace where something cool is always happening this sort of announcement gets a lot of raised eyebrows. Interests piqued, all rooms cleared out to the ante room. There stood a new face and lots of RedBull.

The newcomer introduced himself as a representative of RedBull who wanted to formally invite hackrva to participate in the RedBull Creation contest. He told us about RedBull working with the hacker / maker community and gave us some, not much detail on the background of the contest. Having delivered his message he had one more thing to give us; a gift. He alluded to the gift being a mystery challenge unto itself.

 

Armed with this knowledge we eagerly dug into the gift; a small rectangular box wrapped in heavy paper similar to a grocery bag. Inside we found an ornate laser cut wooden box. The top interlocked with the sides like square key teeth in a lock. There was an inscription on top. A grand welcome to a challenge of technical prowess, problem solving, sleuthiness,  as well as trivial knowledge.

 

We removed the contents of the box and after some soldering, connecting it to a TV,  a computers USB port, and even an original Nintendo Entertainment System controller the gift had us firmly within it’s geeky little grasp.

What secrets did the box hold? What mysteries would we defeat? Come to the next hack.rva weekly meeting to find out. You’ll be amazed.

Spoke POV Class, April 30

March 12, 2011

I’d say, “Pimp your bike” but it should be “Geek your bike.”

Spoke POV  (Persistance Of Vision) is a device to attach to a bike wheel to display graphics as the wheel spins. It has a row of LED’s running parallel to the spokes, and they are pulsed in sync with the rotation of the wheel to create graphics. You define the graphics. People have made Pacman chasing a ghost, and lots of cool stuff. See it in action here:

Hack.rva will have a class where you will build a Spoke POV for your bike. We will help with the assembly and soldering. The price includes the kit. There are three levels. Details can be found here:

Join us and build your own Spoke POV!

Now at a New Location

March 12, 2011

Hack.rva has moved to 1906 North Hamilton street, Suite E. We are in the back left corner of the courtyard. We have an open meeting every Thursday night from around 7:30 to 10PM. There is no formal meeting. It is just a bunch of people building, destroying, coding, talking about technology, computers, programming, or anything that comes to mind. Sometimes people bring their latest cool project, like a Dirod electrostatic generator, or a Spoke POV. People bring junk they don’t want, and other people grab the junk for a project. Come by and hang out any Thursday night.

Call for Class(es)

September 25, 2010

Everybody needs some class, and hackers are no exception. That’s why we’re calling upon you, blogreading community, to contrive and develop and teach any and all that tickles your inspiration.

Be it knitting, quilting, cooking or making of any sort, a class can be made of it. We’d be interested in seeing new and interesting API’s highlighted. Come and shed light on any developments that have enlightened or inspired you recently. These can occur in an official capacity, with tickets sold and red carpets rolled out, or they can be in the form of five to fifteen minute lighting talks or developer sprints.

Please visit our wiki, become a wiki contributor, and drop a line in the classes section. Or, join our mailing list and provide the information there. As a wiki mod, I’ll be happy to post it to the wiki for any and all to see.

Hackerspace Expansion!

July 26, 2010

“Many hands light work makes.” Jim D. told me that. I’m too ignorant to know who he was quoting, but I reckon it’s true.

It started at 0700 on Saturday, the 24th day of July, 2010. I was tasked with porting the hack.rva wiki from it’s current location to a new one with better access control. It was built in about fifteen minutes and hardened enough in about half an hour. I told hack.rva via the mailing list. Fifteen minutes later John and others had joined the fight and we had the majority of the wiki ported by 1000. At 1130 I rolled to the space to throw my hands in with the others in an effort to expand our space.

Will was already there, working on a project of his own design; a diagnostic breakout of some kind that would help him troubleshoot failing window relays in his ride. Flux was flying and the whole place fairly reeked of solder fumes and madness. It smelled like impending victory. At 1230 he had to break for a lunch appointment for some lads from his old campfire.

As soon as Will departed, Carlisle rushed in struggling under the weight of a cooler that was filled to it’s upper edge with sodas and waters and other means of hydration and tools that we would definitely need. If a thing is worth doing, its worth doing right. Soon the space was alight with wild-eyed hackers and makers that all shared a lust for a larger workspace and a higher order of organization. In a frenzy of scrambling hands and feet, all of the dead, near-dead and soon-to-be revitalized tech was moved away from our work area. Following this, the relocation of the wall began. There was some initial deliberation as a solid plan of attack was formed. Then screwdrivers, electric screwdrivers and drills began driving and screwing and drilling away.

Making short work of the wall.

One team was making short work of the wall while another began to assess our lighting needs and available options. A team was dismissed with a list of parts consisting of Corey, the half-mad getaway driver, and I, the harbinger of the list. Lowe’s was our scheduled port of procurement. The team departed.

In the space, snags were appearing in some of the most inconvenient places. A distress call was made and a line-item was added to the list. Longer drill bits were needed to defeat the wall, and we weren’t about to be stopped by something as simple as Newtonian physics. Corey found his way to the aisle of bits and deftly produced one of the proper shape and function. The list fulfilled, we rushed out the door with loaded carts. Filling the car as hastily as we could manage, we jumped in. The immaculately tuned engine roared to life and the smell of roasting tires filled the parking lot as we made a desperate attempt to evade the long arm of loss-prevention.

Upon our arrival at the space, we were greeted with cheers of approval. Tools and various apparati and unsundries were handed out to eager makers waiting to accomplish their tasks. Luke, the light-bearer for the moment, inquired, “How ’bout that chain?” Chain? Rats! We had forgotten the chain that was needed to hang the fluorescent fixtures. We hung our faces instead, in shame. Luke dismissed us, and we were off for another grand caper.

In the meantime the other denizens of the space had all they needed to wire up the rest of the lights. A less-than-structurally sound ladder was extracted from the lobby cave on floor One. Let it be known that there are isn’t a coward among hack.rva, but we all can read, and the ladders 250 pound weight limit was enough to dull some of our eagerness to mount the rickety wooden beast and handle the work that waited on the ceiling. Luke, Jim and a few others that I can’t recollect as Corey and I had only recently arrived from our latest bout of chain-thieverings, had mustered the cojones to summit the ladder, with some folks footing, and begin the truly arduous task of threading wire, strapping conduit and mounting boxes and outlets to the ceiling, into which we may later plug the newest round of fluorescent lamps in.

Some were footing ladders, some were reorganizing and others were putting the finishing touches on the wall. It took the better part of three hours to handle the electrical work, up to and including testing. Our final task was to reorganize the tech. This consisted of shifting everything but the library to another part of the space to be inventoried at a later date. At 1900, we parted ways. The Work Waits!

A cleaner space

* There was nothing stolen in the process of writing this blog entry, or in the process of expanding our space. We’re not on Lowe’s most wanted list, but rather their faithful and loyal VIP customer list.

Python Class Recap

July 22, 2010

The first Python class is over! Thanks to all who attended!

At the class we tinkered with Tkinter and slung SQL commands with SQLite. Next time there may be some GTK programming tossed in, or possibly a bazaar breakout for those that have never tried version control.

Now it’s your turn! I’m placing a call to all Python programmers in HackRVA to share some code with the rest of the group. You can do this via the mailing list. Naturally I ask that you please refrain from posting anything that will get you fired. I’d like to see what sort of applications everyone likes to work on.

I’ll start, I have a CRUD application on Launchpad that has some sort of neat stuff in it. I’ve started automated testing of the interface via D-Bus and there’s some SQLAlchemy in there for folks who have never worked with object-relational-mappers to look at. You can browse the code at http://launchpad.net/eesu.

Have fun programming folks! Also, you don’t necessarily need to post code. You can describe what workflow you prefer, suggest IDEs that we may never have heard of and inform us of interesting libraries and design patterns. Grow, build and communicate!

Intro to Python, this Saturday!

July 12, 2010

Come learn about python this SaturdayThis Saturday, from 10:30am to 04:00pm, is the Introduction to Python Programming class by Clint Grimsley. We’ll be covering a wide range of topicalities and tools to help everyone get started in a language that’s equally suited to rapid application prototyping as well as full scale application development and heavy data-lifting. You too can learn the language that helps companies like AstraZeneca, Honeywell, Industrial Light & Magic and Google keep their operations running smoothly. We’ll also be covering how python is used pervasively throughout certain operating systems and applications to provide application programmer access to functions that you thought always required user intervention.

Come get plugged in and learn a language that will help you be more productive no matter where your hackery leads you!
