Final Post!

Posted by toast May 3, 2011

Dear Intertubes,

      We did it, we have made what many  thought was impossible, a class  room clicker with a KNOB! So why did we  go with a student feed back  device? We polled a bunch of teachers, all  the ones who weren't drunk  wanted just this, an affordable class  clicker! So thats what we set out  to do. What is so great about our  knobby clicker? First off its cheep,  cheep, cheep! Student units cost  $10 and teacher base stations cost a  whopping $7 dollars, both are  significantly cheaper than comparable  commercial products. The PCB  design is single sided for easy DIY  fabrication. Except for the radio  and microcontroller (that are still  simple enough to source online),  all parts are widely available at your  local electronics store and if  necessary parts can be interchanged with  similar parts. We are  particularly proud of our dope web user interface  which is easy to use  and easily extensible, coming preconfigured with  widgets such as roll  call, multiple choice questions, focus group, and  buzzer. It also comes  with pong! Way awesome! Here are some videos,  check 'em out!


This is a screen cast of some of the web user interface widgets:



so exciting!


Heres a little demo of multiple choice in 3 answer mode:

 



impressive, no?


And you all wanted to see the focus group in action didn't you?



of course you did.



Our documentation can be found HERE. We will continue to update our repository in the coming weeks.

Third Post!

Dear Adoring Fan Base,
Here at HacDC, the district's number one hackerspace, we have been hard at work. The last two weeks have seen much progress on our kickass GGHC entry. The bits of hardware are now talking to each other through thin air using the awesome power of electro magnetic waves. The current challenge is scaling the current set up to be able to handle lots and lots of units. Next week Elliot hopes to start implementing uber knobs. The web app is going well, the framework is in place, and test web pages are looking oh so good. We are particularly proud of how easy and intuitive it will be to extend the web interface. The next big hurdle is going to be working out the web to serial interface.
xoxo,
hacdc


p.s. We just solved the serial interface problem, turns out it wasn't a problem. The next big hurdle is refilling the fridge, seems we drank all the beer.

Second Post!

So its been a week since our last trek to the interwebs to report on our GGHC progress. We have made some.

 

Toast spent countless hours partying with teachers and high-school IT staff, trying to understand what educators really needed from the open source community. Brad burned the midnight oil, spending many late, post-work nights hammering out a web interface for our project that didn't lead browsers to panic at the threat of cross site scripting. Elliot has been using his awesome sourcing powers to find us the ultimate deal on components, while making tough choices on the physical implementation of our mind-blowing project.

 

This week we have decided to unveil our ultimate, inventive, creative and totally unique answer to the Great Global Hackerspace Challenge, we're making a classroom clicker!

 

The basic system is comprised of two elements: student clickers and a teacher's aggregator (Elliot wants to call this the "aggro-gator", Brad is skeptical).  The clickers are based around a microcontroller connected to a radio transceiver, with buttons, an LCD screen, and an analog rotary knob! The teacher's unit receives data from the students' clickers and passes them off to an integrated web server with flexible display options. Other options we're interested in investigating include peer-to-peer interaction between the students' devices and extensible scripting on the teacher side.

 

Q.E.D.

Hey all,
This is HacDC checking in with the first blog post for the Great Global Hackerspace Challenge. We're a non-profit, member supported, community space that provides the tools and expertise to make, break and improve technology. We offer multiple classes a week on everything from yoyoing to microcontrollers. This week We're looking forward to the launch of SpaceBlimp IV to gather more data on near-space. The HacDC braintrust include artists, space flight controllers, computer scientists, econometricians and professional partiers. We plan to use every mind with spare cycles to beat the pants off our competition and educate the children (who are the future of tomorrow).
Our core philosophy is founded on the three B's: beer, brainstorming and high-fives. HacDC's goal is to create the atmosphere and community to empower people with the knowledge and skill to accomplish their projects. We are a do-acracy. We encourage our members to do anything that needs doing in our space. In that way our space can be a bit chaotic, but it's all in good fun. Membership is cheap and open, and we welcome anyone from the greater DC area to join.
This week we really took the three B's to heart. After a few nights of "meeting" we've come up with some killer ideas, some may even be implementable. We were vaguely disheartend when we found out that other hackerspaces had similar plans.  What can we say, collective subconscious?   We have decided that our only recourse is to do it bigger and better than everyone else. 
Stay tuned for more update. HacDC out.
