NERP Tonight — Wireless Toys

NERP Tonight — Wireless Toys

The Internet of Things (IoT) need lots of options for wireless communication hardware. Lots of variables are involved in choosing the wireless chip or module that links your new Thing to all the other Things.

A popular last millimeter link is UART based serial. the big end of the link can be wifi, or uart-style data., or whatever convention you come up with. This class of hardware has been around for a long time. The serial to wifi link used to be called a com-port redirector. Commercial units could easily cost $200. The competition pressure brough on by the IoT movement has produced a crop of really inexpensive data links. They list now on Amazon for $2-$10. A lot of them have Arduino sample code available. I just bought two different boards from Amazon, and tonight I’ll evaluate one or both units and see what’s involved in making them go.

PS: Yum Watson Edition

1024px-IBM_Watson

Using a beta version of Chef Watson, we will attempt to create whatever wacky recipes come out of Watson’s “mind.” Come join us for some artificial-intelligence driven fun!

The way it works: you input ingredients that you have on hand into Chef Watson, which will then output a recipe for you, usually adding more ingredients. Feel free to bring your own, and we will probably be making a trip to Jewel.

Where: PS:One Kitchen
When: Tonight: Sunday November 23, 2014 at 6 PM

SIGBOT meeting: Thursday, November 20, 2014 @ 19:00

This month for SIGBOT, we’ll be having a special guest lecturer. One
of our own members, Darold Higa, will be presenting research he did
where he used genetic algorithm techniques to simulate interactions
between agents in settings that resemble our human history. The

Maker Art: (Another) Opening Tonight in Pilsen

DSC_6394 group

My knitted-circuit artwork, Electronic Damask, was in a gallery show, NoFi, at Chicago Artists Coalition, October 24 – Nov 13. The piece was a collaborative effort, put together through the volunteer efforts of close to two dozen PS:One members. PS:One really represented at the Oct 24 opening, and I managed to drag most of us in front of the camera for a group photo with the artwork. (Thanks to Everett for the photo!)

If you missed the fun that night, you’re in luck. Electronic Damask has already been tapped for another show, and with an opening tonight in Pilsen, from 6 – 10pm.

This show should be of particular interest to PS:One members. It’s called Technologic and it “celebrates making art through technology”. It features some amazing stuff made with 3D printers, LCD screens, CNC watercolor painting, and of course a certain knitted e-textile.

The gallery, Chicago Art Department, is located at 1932 W Halsted in East Pilsen’s Chicago Art District (#8 Halsted bus runs right past it). Tonight’s opening coincides with the district’s 2nd Fridays gallery night, so there will be other openings all over the neighborhood.

You can find preview photos of the show on the facebook page. Full info is below. The show runs until December 6.

TECHNOLOGIC
curated by Chuck Przybyl

Friday, Nov 14, 6-10pm

An exhibition that celebrates making art through technology. Work featured will include robotic drawing, 3D printing, laser cutting, textile circuitry, algorithmic art, image slicing, circuit bending, and prosthetics. Although often unsung – artists having access to new technologies has historically pushed and propelled creative endeavors. The exciting new technologies of today have been pushing the overall culture of DIY and propelling the Maker Movement. This is a participatory culture that embraces tools and empowers masses of people to innovate and create. Technologic explores and showcases not only how art is currently being produced with new tools, but how fringe technologies can be used in progressive and cutting edge ways.
Viewers also have an opportunity to “go deeper” to gain further insight through series of discussions and workshops as well information on the processes at the exhibit.

Technologic is curated by Chuck Przybyl for Chicago Art Department.
Artists: Tom Burtonwood, Christopher Furman, Harvey Moon, Luftwerk, Jesse Seay, Nathan Davis, Christopher Breedlove, Christian Oiticica, Leo Selvaggio, Antoine Kattar, and Russell Prather

Opening Reception Nov. 14 – 6-10 PM
3D Printing Workshop with Tom Burtonwood Saturday Nov – 15 – 2-5 PM
Panel Discussion  Saturday Nov – 22 – 2-5 PM

PS:One Knitting Pattern

2014-10-30 23.54.26

I’ve been tinkering with a knitting pattern based on the PS:One logo. This one knits up easily on our electronic machine, with a minimum of long floats. Find the pattern below– feel free to improvise and improve on it!

NERP Tonight — JTAG on the Brain

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.

Electric_hair_curler / Brain-Machine Interface

Joao (“Gamblit” on the PS:One mailing list) will give an introduction to JTAG at NERP on Monday. JTAG is an important tool for embedded developers, manufacturers, and hardware hackers who do reverse engineering. The JTAG interface is included in all but the smallest processors. For use in degugging, JTAG provides real-time read/write access to a chip’s cpu, i/o systems, ram, and mass storage. It gives a user live access points inside a running cpu from which they can take over its brain, or just burn a fresh rom.

Physically, JTAG consists of a small set of pins on a microprocessor, a hardware interface device, a cable connected to a host computer, and a (not physical) protocol. JTAG is most generally useful for programming the flash in embedded controllers. That much is simple. The rest, of course is software.

Joao’s tools and target will include:

– Linux Host (Fedora VM)
– GDB (GNU Debugger) and DDD as debuggers
– No IDE (VIM and direct GCC if I need it)
– Olimex USB JTAG and TIAO USB generic interface
– Olimex Atmega128 board (Atmel Atmega128 MCU)

Joao says:
I’ll be talking about flash programming and debugging software running on a
micro-controller. I’ll also be showing that it can read and set
micro-controller pins but not getting into depth about how that actually
works, as that would need some additional low-level explanation. Depending
on feedback and available time I might explore a bit of it.

Laser cut some simple masks for Halloween

Masks-graphic-WEB

 

There are a lot of online mask patterns that can be printed and cut out with scissors, but it would be much nicer to laser cut one. Let the laser do the hard work. I did these four mask designs tonight; they are perfect for a last minute costume for makers on the go or their kids. Now you can put the roll of toilet tissue back and do better than being a mummy this year. Download the patterns on Thingiverse here.

Solder Party this Saturday

WEB-Chip

This Saturday I’m celebrating my birthday with a solder party in the PS:One Electronics Lab. Everyone is invited to join me in building a large electronic art work for my upcoming gallery show No-Fi, at Chicago Artists Coalition.

There’ll be pizza, cake, drinks, and lots of knitted circuit boards. Come any time and stay as long as you like. We’ll be there til we run out of things to solder and/or food. Please RSVP on Meet Up so we can plan ahead.
