NERP Tonight! FPGA’s with Ste

NERP is not exclusively raspberry pi, the small computer interest group at Pumping Station:One in Chicago.

Ste Kulov (like “steve” without the “ve”) is the signal processing guru of Pumping Station:One. He’s also a great teacher who’s enthusiastic about sharing his knowledge of the theory and practice of analog and digital circuit design. Tonight Ste will show NERP what FPGA (Field Programmable Gate Array) chips do and how to use the chip manufacturers’ development tools.

FPGA’s are very fast logic chips that can perform better than microprocessor CPU’s in a number of high throughput applications. FPGA’s are programmable, but FPGA programs aren’t necessarily seqences of instruction like a C program would be. In fact, on an FPGA you can “write” a CPU. All the cool kids are learning to use FPGA’s, and you should, too!

Tonight’s agenda from Ste:
1.) What are FPGAs & CPLDs and what do they do?
2.) Why would you want to use one?
3.) Explain how you would program one using a hardware description
language such as VHDL or Verilog.
4.) Go over a quick Verilog example & demo of displaying “NERP” on the
4-digit 7-segment display on my dev board.
5.) With the remaining time, demo off my Nintendo DS video output
project to illustrate the neat stuff you can do with these things.

NERP tonight with Drew: Beagle Bone and Pi Face

beagle-hd-logo

NERP is not exclusively raspberry pi, the small computer interest group at
Pumping Station:One in Chicago.

Tonight Drew Fustini will demo the Beagle Bone.

BeagleBone (http://beagleboard.org/bone) is an open source, low-cost
credit-card-sized Linux computer that connects with the Internet and runs
software such as Android 4.0 and Ubuntu.

BeagleBone is capable of interfacing to all of your robotics motor
drivers, location or pressure sensors and 2D or 3D cameras. It can also run
OpenCV, OpenNI and other image collection and analysis software.

Through HDMI, VGA or LCD expansion boards, it is capable of decoding and
displaying mutliple video formats utilizing a completely open source software
stack and synchronizing playback over Ethernet or USB with other BeagleBoards.

Drew will also hit the high points of a Raspberry Pi interface board called the
Pi Face (http://pi.cs.man.ac.uk/interface.htm)

Pi-Face Digital is the first of a range of interfaces to allow the Raspberry Pi
to control and manipulate the real world. It allows the Raspberry Pi to read
switches connected to it – a door sensor or pressure pad perhaps, a microswitch
or reed switch, or a hand held button. With appropriate easy to write code, the
Raspberry Pi then drives outputs, powering motors, actuator, LEDs, light bulbs
or anything you can imagine to respond to the inputs.

Circuits and Arduino (session 3) Sun. 3/18 12:30-2:30pm

Session 3 of the Circuits and Arduino class will meet Sun. 3/18. from 12:30-2:30pm. Session 3 will be Motors and Actuators part 1: Servos.

In session 2, we read analog sensor input into the Arduino, and had the Arduino print the data to a character display.  In session 3, we will read sensors with an Arduino, and then interpret the data to control the position of a servomotor. If you want to build an Arduino-controlled entity that has physical motion, this is a very good place to start.

Arduino printing sensor data to a character displayThe only new hardware component introduced this week will be the servo. I’ll have a small quantity of servos available for sale on Sunday for $12 ea. For class you will need only one servo, however there is the option to use more than that for your own experiments.

 

Who: everyone (members and non-members are welcome), seating is limited to 10 people. Reservations are preferred but not required.
Cost: $12 for a servo, unless you bring your own
When:
 3/18/2012 12:30-2:30pm  (Please note the time change.)

Circuits and Arduino (session 2) 3/4/12 3pm

The second meeting of the Intro to Arduino Class will be Sunday March 4 at 3pm. There are 10 seats available, but observers are welcome after the 10 seats are filled. In the first meeting, we learned about soldering and reading circuit diagrams by making an Arduino work-alike from raw components and a blank proto-board.

In the second class we’ll

  • learn to use a breadboard for doing quick “sketches” with electronic parts.
  • use a pushbutton, a photoresistor, and a potentiometer to learn about providing inputs into an Arduino program.
  • use a serial data connection to communicate with a small LCD character display that can show two lines of text.
  • have a first look at ways of powering our circuit when it’s disconnected from the computer.

If you weren’t at the first meeting and therefore don’t have a copy of the board we made, you can still participate by bringing your own Arduino or Arduino-compatible.

The session-2 kit has a breadboard, LCD character display, heavy duty 5-volt adapter, and a couple of other things. If you attend, you should purchase the kit. Price for the session-2 kit is $29.00

I’ll take reservations by email and payment for the kit on site.

 That’s probably all that will fit in two hours. Last time we ran significantly overtime. This time, we’ll keep it to two hours.

Who: everyone (members and non-members are welcome), seating is limited to 10 people.

Cost: $29 for the kit. and to arrange payment.

When: 3/4/2012 3-5pm

Reservations: email ed at kineticsandelectronics dot com

This will be a 4-part series or so. There are 10 seats available, but observers are welcome after the 10 seats are filled.

I’ll have a kit for sale on site to get people started. Price is $29.00. It has a board, chip, USB adapter, LED’s, and a couple of other things to get you started. Because I’ll be packaging the kits for the occasion, I ask that if you attend, you purchase the kit.

I’ll take reservations by email and payment for the kit on site or by Paypal.

The first session (2/19) basic description is:

  • How to Solder: Solder up an Arduino workalike.
  • How to run the Arduino development application on your laptop.
  • Basic Arduino program structure. Run an LED. (Hello World blinky).
  • Show where the built-in examples live in the IDE. Run an input example and an output example.
  • For inspiration, demo a couple of circuits with an Arduino and some connected hardware.

That’s probably all that will  fit in two hours.
Future sessions may discuss Arduino-compatible accessories, motors, simple sensors, and so on. There are many possibilities.

Who: everyone (members and non-members are welcome), seating is limited to 10 people

Announcing: Creative Code Workshops

:(

Creative Code Workshops

workShop[0] = Processing;

Over the past several decades of advancement in computer technology, a fledgling movement of computational and digital media art has emerged. Initially the province of a handful techno-savvy pioneers, today there is a wide range of tools and resources available to artists and designers, drastically lowering the barrier of entry for anyone interested in computer art. This series of Creative Code Workshops explores the sometimes-nebulous territory of Code-As-Art, bringing creatives and technologists together to make interesting, complex work.

In our first workshop, we will explore Processing, an open-source programming language and framework developed for the visual arts community. Originally created to teach computer programming fundamentals within a visual context, it has grown into a robust yet flexible platform serving both artists and pedagogues. Its open-source license has led to a vibrant developer community that has contributed to its extension into other regions of computational media, including computer vision, audio processing, networking, data visualization, and tactile media. This hands-on workshop will help both artists looking to get their hands dirty with computer programming and programmers looking to explore their creative side.

Where: Pumping Station: One. 3354 N. Elston, Chicago, IL.
When: Saturday, September 25th, 2010, 4pm.
Cost: FREE
Accessibility: Open to the public

  • BARcompany – Start a business over the weekend
  • Random other activities

Guests from a multitude of backgrounds will be in attendance, including programmers, developers, engineers, tech students, open-source advocates, entrepreneurs and business professionals.  Participants are encouraged to share, learn and break off into smaller focus groups, brainstorm and collaborate on any project or idea.  Professional networking is highly recommended.

Words really cannot describe this event! Take a look at the videos and pictures linked from their website:  http://barcampchicago.com/

BARcompany

Returning to BARcamp this year is BARcompany, which challenges small groups of participants to come up with an idea and create a company around it in about a day’s time. The resulting companies and ideas are presented at the end of the weekend to the conference attendees and to a panel of judges made up of local, influential people in the technology community. The team who organizes the best company has a chance to win prizes which may include server hosting for the developed web application, co-working space and possibly even some start up capital.
