NERP Tonight: A Simple Wireless Link for Serial Data

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.

Amongst the Maker community ZigBee® is usually thought of alongside the XBee® modules from Digi Corporation. The little blue irregular-hexagon shaped boards mean “wireless data” to a lot of folks. XBee is in fact the name of a family of wireless data modules that share the same form factor and blue color. The family includes ZigBee modules, DigiMesh modules, WiFi modules, and IEEE802.15.4 radios. Depending on the model, the data radios can do point-to-point, peer-to-peer, star, and mesh networks.

If you’d like to play around with wireless data a good place to start is replacing a serial cable with an XBee Series 1 module. There are two power levels to choose from: a 1mW module that can work to a distance of 300ft, and a 60 mW module that can work to a distance of one mile (in perfect conditions).

The Series 1 modules are usually used as IEEE 802.15.4 data radios. ZigBee and several other protocols are built on top of 802.15.4.The 802.15.4 spec provides the physical and MAC layers to serve higer level protocols. It’s a just enough support to get bytes sent from A to B. One nice thing about working close to the metal is that, once the hardware is set up, it’s fairly easy to push bytes around. You can even make up your own simple ad-hoc protocols if needed.

Tonight at NERP, I’ll show how to set up a wireless data link between two devices that can communicate at 300 to 115200 baud. I’ll show XBee XPB24-AWI-001’s moving serial data, and how to set up and test the modules using the X-CTU software from Digi.

As a side-note, the Internet of Things is creating a demand for better and cheaper wireless data connections. It is common for the Things to speak a local protocol that is propietary or unique to their class of device and for the relevant parts of the machine to machine dialog to be passed upstream through a server or bridge.

ZigBee® is a trademark of the ZigBee Consortium

Last 36 hours for submissions!

designcontestWe’re down to the wire here, everyone! This is your last chance to submit designs before the deadline! Get ‘em in before the voting starts in 2 days!

You can submit your entries throughout this month of September, with the deadline on the 30th. after that will be a week of member voting. The winning submission will get a complete set of the shirt (any size), sticker, and pin, as well as a “special meet and greet with the president of Pumping Station: One” (Bry asked me to include that last bit).

Guidelines for submissions:

  • Designs are for the tees, 1″ buttons, and 3″ stickers(round or square, depending on the chosen design). Unless you think the design will be optimized to look good in all three formats, I suggest you edit your designs for each application. By all means, have the same elements in each, but keep in mind that the button has less space for detail than the shirt.
  • Unless you’re designing in vector format, make sure your original copy will be of sufficient size and detail. The canvas you work in should be about 10″ wide by 15″ tall and at LEAST 400PPI if not working in vector.
  • Be excellant! No inappropriate themes. Remember that PS: One is a safe space, I know we have just f@*!ing do it as a central theme, but keep it PG or your entry will be invalid for the contest.

Send your submissions to info@pumpingstationone.org with “Design Contest Submission” in the Subject line

Galileo Girls

logo

We are teaming up with Intel, Coder Dojo Girls and Coder Dojo DCU to bring about a special event for the International Day of the Girl on October 11. A day long hackathon style to give an introduction to the Galileo board. The participants will learn basics of coding an embedded environment and get hand an experience with hardware. The second half of the day will focus on creating electronic fashion  wearable technology and funky robots.

Attention!

There will be an AGM on Tuesday 14th October, the meeting is open to all (member and non-members alike) and is a chance to discuss issues around the space, review activities that have taken place over the year, and put forward suggestions about Hackspace. There will also be elections for the positions of Directors of the space.

If you have and points of order/interest that you would like raising add them below or to the mailing list and we can get a running order together.

Hope to see you there!

Two Applied Sciences Events this Tuesday, Sept. 23rd!

As written by Ryan:

First up is SEM Office Hours at 7 PM

We’d previously had problems with the SEM’s vacuum system that prevented us from looking at new samples. This is now fixed! So to celebrate, I intend to do some sample preparation. (We’ve got a 3D printer nozzle to measure and examine, and a piece of color slide film covered in mold.) This will be the first time I’ve opened the sample chamber for a public demonstration.

I’d also like to thank two people who made this possible. Bruce McConachie donated the funds to purchase the parts to repair the scope. And Fitterdave did some very difficult TIG welding to fabricate a custom adaptor.

We we will be ending SEM Office Hours early to accommodate the second Applied Sciences event of the evening. At 8:30, Elizabeth Koprucki will be presenting a lecture: Explore Our Solar System: Data from Space and What You Can Do With It.

So come on out, and, in the words of the venerable Sarcastic Rover:

Let’s Do A Science!

Beer Church Brew Day: Saturday 9/20

We’ll be having a beer tasting and brew day on 9/20 (Saturday) at 12:00PM noon. We normally brew on Sundays, but we’re mixing it up this time. We’re looking to make an Octoberfest Lager or a Märzen, but it’s really up to whatever the people who are going to participate in the brew want to do.  Our temperature control system Chillmon is working, so any fermentation temperature is possible.

The brew is a very hands on workshop, even first timers can try their hand at various parts of the brewing process including recipe development, prep, mashing, grain grinding, mashing, sparging, boiling, pitching, kegging, and setting up our in-house bar.  We go from malt, hops and yeast infusions all the way to serving out of our chilled tower tap system. If you just want to watch and listen, that’s fine too. Any idea or person is welcome.

We’ll be tapping our Rosemary Stout for the first time this Saturday. If you’d like to share anything please bring it (craft brew, homebrew, whichever)! We love to talk about your homebrew or the interesting beer you made or found that you want to experience with other beer aficionados.  You must be 21 years old to attend Beer Church.

What’s a hacker?

I get asked about being a hacker, what's a hacker, isn't hacking bad etc etc, all the time. Thanks Nova Labs for putting together this video which says everything I would have!
