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.

Call for NYC World Makerfaire Volunteers!

We’re looking for at least 2 more volunteers to help out with Noisemakers (Github link) at the World Makerfaire in NYC September 20-21st. We’re getting sponsorship for a booth at the Makerfaire, and it would be awesome to have as many volunteers representing Pumping Station: One as possible.

noiseotron2

There is also a vote currently to get funding to make the noisemaker kits, which each cost about $5. The details are here.

You would get free entry into the Makerfaire for volunteering, and we’re just looking for people willing to volunteer a few hours; we are going to be at the booth Saturday and Sunday from 11 AM-2 PM. You will have plenty of time to enjoy the Makerfaire:)

Staying in NYC is pricey, but I have reserved a hotel room 2 mi from the Makerfaire and would be willing to split with people (so far the room is split between 2).

Please email me if you are interested in volunteering and representing PS: One at the World Makerfaire!

Thanks!

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!

CNC Build Club – Let’s Talk Stepper Motor Drivers.

178

Stepper motor drivers are the things that power most of our DIY CNC projects.  There are dozens of choices.  What makes a good driver?  We will talk about that.

I will bring as many as I can find, which could be a dozen or more. Gecko’s, Leadshine DSPs, Pololu, Panucatt, Allegro, TI and others. I even have a three phase closed loop driver and motor.

 

2133angle2_zps989f1d86

 

Special attention will be given to the Trinamic TMC261. This is a new-ish driver chip that has a lot of cool new features. The most interesting is it’s sensorless load detection. This means the driver can sense the load on the motor. This allows it to do a few new tricks. One is to dynamically adjust the current. You can set the maximum current quite high, but it will only go that high if the load on the motor requires it. This keeps the driver cool, yet allows it to power through higher loads and accelerations. The other trick is stall detection. If the motor totally stalls this is sensed and a fault pin is activated. This is being used by people to eliminate end stop switches. Rather than using pots and pins to set these values, you use and SPI bus. The driver also has a very high voltage range for a chip this size of 9-60VDC. Stepper motors love higher voltages

eval

I have a eval board we can play with.  This board has a motion controller on board and can take the steppers up to ludicrous speeds.


The CNC Club is a monthly meeting of Chicago area people passionate about learning, building and using digital fabrication equipment.  It is held at the Pumping Station One Hackerspace.  It is open to non members.  We also have a Google Group calledCNC Build Club.
