NERP Tonight — NVIDIA’s CUDA: 192 Parallel Procesors

NERP is not exclusively Raspberry Pi, the small computer  interest group at Pumping Station:One in Chicago.  NERP meets  every other Monday at 7pm at Pumping Station:One, 3519 N. Elston  Ave. in Chicago.

Tonight at NERP, Sevin Straus will give an introduction to NVIDIA’s CUDA architecture. CUDA uses a cpu to farm out pieces of a task to the parallel processors in a video graphics chip (GPU). [more below]

Nvidia wants lots of developers to know about CUDA. To that end, they have put together a complete development environment. In the best of all worlds, the environment should be usable on Linux after simply running “install.sh”. It’s never really that simple. Sevin has put together a working develpment system targeting the Jeston development board. Tonight he’ll show us how he did it and some of the included demos.

A sense of what CUDA is about would include these thoughts collected from various parts of the CUDA website:

CUDA® is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU). A GPU consists of thousands of smaller, more efficient cores designed for handling multiple tasks simultaneously.

GPU-accelerated computing is the use of a graphics processing unit (GPU) together with a CPU to accelerate the compute-intensive portions of tan application to the GPU, while the remainder of the code still runs on the CPU. From a user’s perspective, applications simply run significantly faster.

Dream Hackers Club

Lucid Dream: any dream in which one is aware that one is dreaming. 

A few of us got together to discuss lucid dreaming this past Sunday. Among the things we talked about were; the benefits of lucid dreaming, the possible evolutionary explanations for dreaming, and personal lucid dreaming experiences.

We left off with a group challenge to try at home:

1. Wake up earlier than normal.

2. Play ambient tropical ocean sounds.  Click here for ambient music or find your own.

3. Go back to sleep with the ambient tropical sounds playing.

With this experiment, we want to see if we can affect our dream’s setting through audio. You may be able to hear the sounds in your dream, which could place your dream on a tropical beach.

I hope to use these meetings as a way to explore how we can use lucid dreaming, with intention and purpose, to improve and explore ourselves. How can we hack our dreams to get more out of them? Can lucid dreaming become part of our creative process? Join us at our next meeting and feel free to try out the group challenge.  We will discuss our experiences with this experiment together.

Next Meeting: Sunday, Aug 10 at 7pm in the kitchen

Kitchen and PS:Yum Update

PS:One Kitchen

PS:One Kitchen

 

 

 

 

 

 

 

Our kitchen was built about a year ago to fulfill the desires of a group of foodies at Pumping Station: One called PS:Yum. They wanted a place to be able to cook and store food that was separate from the shop. Since then, the kitchen has hosted many fun events like Beer Church and a liquid nitrogen ice cream social. Within the last two months–since June 16th, to be exact–the kitchen acquired a new area host. I recently got a chance to sit down and interview Arturo, the aforementioned area host. He has done amazing work with the kitchen so far and has even grander plans for both it and PS:Yum in the near future.

Since becoming area host, Arturo has not just made the kitchen cleaner and more functional, but has also added much useful kitchenware. Recently, he bought new table and drying mats, to make cleaning up after snacks much easier. He has also started recycling cans, which he plans to melt them down for their aluminum. There was an impromptu hot dog party in the kitchen recently thanks to him. It was a lot of fun and really encouraged people to utilize the kitchen for more than just cooking. The kitchen fulfills a similar function to a water cooler at work; it is a place to get refreshed and take a break from projects to talk to your peers.

PS:Yum now includes anyone who enjoys cooking at PS:One and the people who eat food cooked during PS: Yum events. This essentially broadens the original group to include most people at the space. The high interest shown in PS: Yum is very encouraging. Future plans for the group include allocating some land from the alderman for an urban community garden. Other plans include a session where our amateur chefs cook recipes that IBM’s Watson artificial intelligence has created. Even more future uses for the kitchen include doing applied science experiments and holding cooking related lessons. Contact Arturo, Noonie, or Ryan for more information.

I have to say I am extremely impressed the hard work Arturo has accomplished in such a short period of time and look forward to more improvements and events from the kitchen. Good luck on your future kitchen and cooking endeavors, Arturo!

YouTube Preview Image

You are all invited to an exciting night of gambling-free poker!

Players of all skill levels are welcome! We will be playing Texas Hold ‘Em to raise money for the Noise-o-tron kits we will be teaching people how to build at the South Side Mini Maker Faire this Saturday. We provide this demo for free to Maker Faire attendees, and we’d like to keep it that way so we can help educate as many people as possible! Food will be provided; feel free to bring your own drinks.

So how does the gambling-free part work? The entry fee for playing at a table is $10, and you’ll get a stack of chips to play with. When you are done playing, you turn in your chips for raffle tickets. Each dollar in chips that you have will convert to 1 raffle ticket. At the end of the night, we will have a raffle for 1st and 2nd prizes. Don’t worry, you do -not- have to be present at the raffle drawing to win. As long as you’ve turned in your chips, you have a chance of winning. We will notify the winners via email, and you will get your prize ASAP. What prizes do we offer? You’ll just have to wait and find out! We promise that you’ll like them.

Also: We are looking for a third dealer. Justin and I will be dealing all night, but we would really appreciate it if someone would volunteer to help us deal another table.

NERP Tonite: The New Raspberry Pi B+, and The BeagleBone eQEP

NERP is Not Exclusively Raspberry Pi, the small computer and embedded systems interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago.

Tonight at NERP, Craig LeMoyne will introduce the new Raspberry Pi Model B+: the new and improved version of the highly successful Model B. We will have a side by side comparison with the Model B and highlight the changes.

Servo motors are computer controllable motors that do pretty much the same thing as stepping motors. From a systems perspective they have nothing else in common. Servos use feedback to adjust the motor’s position and velocity. The difference between the target speed (or position) and the measured speed (or position) is called error. Without error, the motor has no reason to move. The type of sensor usually used to detect a motor’s position is called a quadrature encoder. Although servo systems can give better performance than steppers in some situations, servos are more complex and more expensive than steppers. Part of the complexity is reading and making sense of the encoder. Adafruit has posted a video in which Drew Fustini has a good job of introducing some techniques for accessing the special eQEP quadrature decoder module in the BeagleBone Black.

https://www.adafruit.com/blog/2014/07/15/how-to-read-the-position-of-a-rotary-encoder-connected-to-a-beagleboneblack-txinstruments-beagleboardorg/

A PS:One member (me) has a project that aims to use the BBB’s eQEP to control an Etch-a-Sketch. Tonight I’ll show some of the technology that’s involved and progress on assembling the system.

The Internet’s Own Boy: The Story of Aaron Swartz

Come out to see the recently premiered documentary about the life and struggles of Aaron Swartz, Reddit co-founder and political activist.

From Wikipedia:

“Swartz was involved in the development of the web feed format RSS,[3] the organization Creative Commons,[4] the website framework web.py[5] and the social news site, Reddit, in which he became a partner after its merger with his company, Infogami.[i]

Swartz’s work also focused on sociology, civic awareness and activism.[6][7] He helped launch the Progressive Change Campaign Committee in 2009 to learn more about effective online activism. In 2010 he became a research fellow at Harvard University‘s Safra Research Lab on Institutional Corruption, directed by Lawrence Lessig.[8][9] He founded the online group Demand Progress, known for its campaign against the Stop Online Piracy Act.”

NERP Tonite: Pingo means “pin, go!”

NERP is Not Exclusively Raspberry Pi, the small computer and
embedded systems interest group at Pumping Station:One in
Chicago. NERP meets every other Monday at 7pm at Pumping
Station:One, 3519 N. Elston Ave. in Chicago.

Luciano Ramalho is a member of Garoa Hacker Clube in Sao Paulo,
Brazil (http://hackerspaces.org/wiki/Garoa_Hacker_Clube).
Tonight at NERP, Luciano will tell us about the Pingo
project in progress at Garoa HC
(http://www.pingo.io/docs/intro.html). Pingo aims to make
interconnecting small controllers of all sorts easy and
transparent, so that they can use each other’s peripherals. An
example use case would be using Python on a Beagle (or similar)
to effectively “program” one or more attached Arduinos.

From the website:
“Pingo provides a uniform API to program devices like the
Raspberry Pi, BeagleBone Black, pcDuino etc. just like the
Python DBAPI provides an uniform API for database programming in
Python.

The API is object-oriented but easy to use: a board is an
instance of a Board subclass. Every board has a dictionary
called pins which lists all GPIO pins on the board. Each pin is
an instance of a Pin subclass with attributes that you can
inspect to learn about its capabilities.”
