Dean’s Dust Collection System

 

There are many exciting things happening in the shop lately including the ShopBot CNC router and dust collection system. The latter of which I will tell you about now. The dust collection system is a project that Dean is in charge of. He has been diligently staying late in the evenings to work on it, sometimes until 1:00 AM. The dust collection system will be made up of a filter, blower, a Clear Vue cyclone and ducting. The ducting will be attached to the ShopBot,  SawStop table saw, band saw, and other tools in the wood shop.

The air will be sucked into the cyclone by the fan, which runs on a 3 phase induction, 5 horsepower motor. It will then be filtered in two stages. The first stage is the cyclone, which will filter out heavier particles into a trash can below it. The second stage will be an actual filter that will trap all the smaller particles. After that, the filtered air will be blown back into the shop.

There is also a Dylos air quality monitor hooked up in the shop that keeps track of the particles in the air. It can be hooked up to a computer via an RS232 serial port for graphing purposes. Besides that, it displays the current readings on both large and small particles. The hope is that the readings will drop significantly after the dust collection system is up and running.

I would like to thank Michael S. for doing the wiring for this and Dean for his many hours of labor on this project. We all hope it will make the shop much tidier and I am certain it will. Also, Dean would like help installing the ducting, which arrived today!

Hackaday Prize: Emergence

The first two BEAM robots. Johnny and Frankie.

The first two BEAM robots. Johnny and Frankie.

The Hackaday Prize Contest is underway! Community voting has started and will continue until August 4th, which is the deadline for initial submissions. The Grand Prize is a trip to space, while the other prizes are pretty cool too. For example: A milling machine, a top grade 3D Printer and more down to 5th place. There are many minor prizes (read hundreds) as well. I encourage you submit your project on behalf of PS:1 or join a project that has already started. Also see if people want to collaborate on other submissions. The more we submit, the better chances of winning. More importantly, cool things will be made. That’s what what hackerspaces are all about, building stuff with or in a community. Here at PS:1 we have one project already underway with more ideas for additional entries. So far, Greg D. has started the Emergence Project, which combines artificial intelligence, robotics, and evolutionary biology. The results will be “to build a small swarm of robots, give them capabilities similar to that of individual insects, and see if emergent behavior arises through their repeated cooperation and interaction with each other.” The team consists of himself, Jenny, Justin C. and me, Anthony. The next meeting will be this Wednesday, July 9th, at 7-9 PM in the Electronics Area of Pumping Station: One.

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.”

Find NERP and Pumping Station:One
at http://www.meetup.com/NERP-Not-Exclusively-Raspberry-Pi/
and http://pumpingstationone.org/
Doors open at 6:30pm. The next meeting is July 7th, 2014.
NERP is free and open to the public.

Hands-On Science | Experimentation | Curiosity Knows No Bounds

Applied Sciences Chicago

This is a group for anyone interested in applied sciences, including optical and scanning electron microscopy, fermentation science, saponification, herbalism, astronomy and planetary science, and citizen science.

We started this Meetup because many people think science must be done in a lab with expensive equipment. We want to show how easy and fun scientific experiments can be. We will gather to do science, talk about news in the world of science, and have field trips to places like Yerkes Observatory in Wisconsin.

This group is open to people of all experience levels, from complete newbies to working scientists. Bring your curiosity and join us!

Also, please like our page on Facebook. Help us reach 100 likes by the end of July!

Artificial Intelligence Q&A with Tim Winkler, IBM

Applied Sciences Chicago presents:

What will you do with Watson:

Come out this Monday evening from 7-8 to do a Q&A with Tim Winkler, a former PS:One member and software engineer at IBM who works on Watson, the Jeopardy winning artificial intelligence.

Tim has worked for IBM for 10 years and on Watson for about 3 years. He works with natural language parsing and machine learning.

Watson processes unformatted data, i.e. natural language documents, and not structured databases, so part of Tim’s job is to work on ingesting that data and making sense of it. One of his current projects is cognitive cooking, in which Watson comes up with recipes for us to cook and is really awesome:)

Cognitive Cooking in the IBM Cloud:

So come with any and all questions about one of the most famous robots in the world:)

When: Monday July 7, 2014 7-8 PM
Where: Lounge

DC Circuits Class Notes

DC_circuits

Thanks to everyone who came and participated in the circuits class this past weekend.  There was a lot of material that was covered and there was no way to go through it all in exhausting detail.  So I’m making available a scanned PDF of the notes I wrote for the class.  Enjoy all the spelling errors, in addition to the one found above.  The edges might be cut-off in some areas, but it’s the best I can do:   DC_Circuits_SK

Also, Carl Karsten did the exhausting (and usually thankless) job of recording a video of the class.  It can be found here:

http://videos.pumpingstationone.org/video/32/basic-electronics-dc-circuits-class

The solution to the bonus question was never explicitly stated in the video, so here it is:

Hack Your Coffee!

image_9

Have you ever felt dissatisfied?

Have you ever woken up in the morning, considered all the projects you had ahead for the day, all the worthless meetings and teleconferences, and just said, “blah?”

You take a sip of your morning coffee, expecting a moment of brightness, goodness, something to cling onto by the fingernails, to hold you throughout the day, as you say to yourself, “You know, today is gonna suck, but at least I have this freshly brewed Java Supremo from Overpriced Cafe”?

You take that sip… and you say to yourself, “Really?  That’s it?  This is how my day is going to begin, not with a bang, but with a whimper?”

Yes, I too have felt that way.  I had wished there was a way I could seek out bold new flavor profiles in my morning coffee, beyond just “mild” “medium” and “strong.”  I wished there was a way to hack my morning coffee.

Thankfully, there are options.  Today, we are trained to only look for coffee at our grocer, or perhaps at the local cafe where we can pick and choose from pre-selected and pre-roasted coffee, perhaps even pre-ground, for our approval.  Or, we can do things the way our great-great-grandparents did it, which is, we roast our own damn coffee.  There are many ways to do this, one of which is with an air-pop popcorn popper.

image_3

That’s right, this noble device, previously only a monotasked tool to deliver copious amounts of fluffed corn to your gaping maw whilst watching reruns of ‘Love Boat’ and ‘Magnum PI’ can also serve as a way to roast our precious coffee the same way the pioneers did.  Well, not really, but close enough.

Currently only one batch of green coffee beans has been successfully roasted and served to unsuspecting denizens of PS:1 (No, those are not flavor crystals, THAT’S REAL FLAVOR DANGIT) to glowing reviews.  This is only a proof-of-concept batch at this point, with much more work and experimentation to be conducted, but with continued testing and sampling, the overall goal is to create a viable procedure, optimize the process, and eventually create the capability at PS:1 to roast coffee, and tailor to your specific discerning tastes.

The output of this project will include a wiki page with optional training, an understanding of the variables of coffee roasting and how to tweak the process to serve your tastes (i.e. using APPLIED SCIENCE to understand the roasting process), and recommendations on where to source green coffee beans.

More information is forthcoming in a future 300 Seconds of Fame!

PS:One and SSH present: Business Planning for Hackers, Creatives, and Other Out of the Box Types

20140626_0003

PS:One & SSH present: Business Planning for Hackers, Creatives, and Other Out of the Box Types

Facilitated by A. Catherine Noon of Writer Zen Garden.

Taking an idea from concept to execution poses unique challenges. One way is to just do it, throwing enough mud at the wall that eventually some will stick. This is time-intensive and may not yield much more than a mud-covered wall.

There’s a better way. Businesses have been around since the time of Babylon; why not experiment with some tools that have made others successful? A business plan can yield benefits not just from the process of clarifying your goals but as a funding tool. If you can crystallize your passion onto the page then chances are, you’ll have a shot at inspiring others as well.

After all, mud on a wall is mud on a wall.

Over twelve weeks, we will explore our own ideas using tools from right-brained artistic games to classic business school (like SWOT and budgets). You will need a copy of the book, The Creative Entrepreneur: A DIY Visual Guidebook for Making Business Ideas Real by Lisa Sonora Beam, available from Amazon, the Chicago Public Library, and other booksellers.

You will also need a blank journal book, at least 8.5” x 11”. I like the Strathmore 400 Series journals, available from retailers or Mister Art.com; their 12” x 9” is my favorite.

These will be held alternating Thursdays at Pumping Station: One (PS:1) and Southside Hackerspace Chicago (SSH:C). Addresses and links are below the schedule.

Our first four sessions have been well attended and productive. We work in a collaborative fashion, alternating between roundtable discussion and work/play time on our individual projects.

If you’re curious about the process or want to get clear about your own ideas for a business, please check us out.
