August 2014 Book Club

Thanks to everyone who made it to our July bookclub, despite it being mere hours before Dublin Maker. The next meeting will be 7:30pm, Friday 29th August. (And as some of us will be at EMF camp, we’ll be having a satellite bookclub meeting there as well!)

The book for August is ‘Sarah Canary’ by Karen Joy Fowler.

“When black cloaked Sarah Canary wanders into a railway camp in the Washington territories in 1873, Chin Ah Kin is ordered by his uncle to escort “the ugliest woman he could imagine” away. Far away. But Chin soon becomes the follower. In the first of many such instances, they are separated, both resurfacing some days later at an insane asylum. Chin has run afoul of the law and Sarah has been committed for observation. Their escape from the asylum in the company of another inmate sets into motion a series of adventures and misadventures that are at once hilarious, deeply moving, and downright terrifying.”

And because many people are away on holidays around now, and to be mindful that our dead-tree reading members can sometimes need time to locate copies, we’ve set the book for September as well, as ‘Permutation City’ by Greg Egan. More details next month.

And remember; all are welcome to come and chat about the book (members & non-members). Whether you’re in Dublin, or at EMF camp! No charge, ever. But usually some tea and a few biscuits.

*edit* Just a reminder that we have a goodreads group as well to help keep track of suggestions. Come join us!

New toys in TOG Spot Welder

As always at the BBQs at tog there is fire and dismantling of stuff involved. Group of us on Sunday during the BBQ took apart an old welder that was quite useless and converted it to a spot welder check out the video down below.

 

We also put up a few more pin hole photos of which will be posted in a few weeks.

Pre-Maker Faire Poker Night

playing-cards1

You are all invited to an exciting night of gambling-free poker!

Players of all skill levels are welcome! We will be playing Texas Hold ‘Em to raise money for the Noise-o-tron kits we will be teaching people how to build at the South Side Mini Maker Faire this Saturday. We provide this demo for free to Maker Faire attendees, and we’d like to keep it that way so we can help educate as many people as possible! Food will be provided; feel free to bring your own drinks.

So how does the gambling-free part work? The entry fee for playing at a table is $10, and you’ll get a stack of chips to play with. When you are done playing, you turn in your chips for raffle tickets. Each dollar in chips that you have will convert to 1 raffle ticket. At the end of the night, we will have a raffle for 1st and 2nd prizes. Don’t worry, you do -not- have to be present at the raffle drawing to win. As long as you’ve turned in your chips, you have a chance of winning. We will notify the winners via email, and you will get your prize ASAP. What prizes do we offer? You’ll just have to wait and find out! We promise that you’ll like them.

Also: We are looking for a third dealer. Justin and I will be dealing all night, but we would really appreciate it if someone would volunteer to help us deal another table.

Rules & strategy links for Texas Hold ‘Em

littleBits Projects

littleBits

Back in June we announced some Instructables Build Nights featuring littleBits and the new Arduino at Heart modules. We had a lot of members play with the ‘Bits during the last six weeks, and we’re still waiting for Steve to publish the detailed instructions on his “littleBits-powered Vomit-Inducing Machine”, but for now we’ll have to make do with the littleBits Arduino Annoying Machine that Eric and his son built.

I also got in on the action, with two Instructables that (sort of) go together; littleBits Serial Data and littleBits Serial Controller. All of our projects make use of the Arduino module, which add some great programming functions to the littleBits world.

If you didn’t get a chance to play with the ‘Bits yet, we will have four littleBits Deluxe Kits and a bunch of Arduino modules at the space to experiment with. They should be treated like a LEGO set; build something, then take it apart. Hopefully having some fun and learning something new along the way.

(Big Thanks to Instructables and littleBits for providing the kits to us!)

Building Patio Furniture for Fun and Profit

If you’ve ever looked to purchase patio furniture its either cheap and crappy …or expensive and still crappy.

So I decided to make my own. Because I wanted to drink beers on my porch and tell kids to get off my lawn.

With no further ado:

Before During After

Figure 1: My Porch Before, During, After

Step 1: Find Plans.

I’ve never used any Ana-White plans before, but I found these that seemed reasonable. After some review though, I found the cutlist sucks so any of the pieces with angled cuts are listed at final dimensions rather than initial rough cut dimensions. Namely the angled stretchers need to be cut long (34″ish) and then angled. Same goes for the back legs (~22″) and the 2×2 arm supports (~28″). So do your own due dilligence before slicing all your lumber up.

Step 2: Cut All the Lumber

Pine sucks and I hate paint. So I went with Cedar.

Rough Cedar

Figure 2: Rough Cedar from Menards

Cut Lumber

Figure 3: Cut to Size and Length

Rough Sand Cuts

Figure 4: Apply Belt Sander

I recommend using a belt/drum sander on any of the rough cuts to give it a cleaner finished look.

Step 3: Follow Directions (Assembly)

Aside from the cutlist, the plans are straightforward and easy to follow. I built the sides and back as assemblies because I couldn’t transport a completely assembled chair in my car.

Follow Directions part 1

Figure 5: Side Assembly

Following directions somewhat p1

Figure 6: Chair Back Assembly

I deviated from the design a bit as I didn’t feel like using a jig saw, so I just set the miter saw for 45deg and lopped off each corner of the back (which you’ll see in the final assembly pictures)

Starting Assembly

Figure 7: Starting Assembly

I transported the large pieces back to my apartment so I could put it together on-site. I don’t have any pictures of the middle steps, so it kind of jumps from here to completely assembled. Read the directions, you’ll know what to do.

Testing p1

Figure 8: Assembly Done (Structural Testing)

Ta da. A chair.

The beer made up for the sunburn.

Step 4: Finishing

Like I mentioned above, I don’t like paint. So I winged this phase of the project.

I like oil based finished to bring out natural color, so I grabbed a can of Danish Oil. Cedar is naturally rot and insect resistant, but since I had some spray Spar Urethane lying around I figured a coat of that couldn’t hurt either. Lastly, because I like the texture of wax finishes I applied Paste Wax to any of the upright surfaces where you’d touch the chair in normal operation.

Finishing

Figure 9: Done!

I applied the Danish Oil  by hand, which was a pain, but worked out well enough in the end it seems.

Step 5: Build a Second Chair

This second one is a little better finished based on some in-process learnings from the first chair. I picked up a countersink bit to help clean up the exposed screw holes and tried a little harder to be symmetric and even with the holes as well.

I need to either build a table, or figure out a way to add a cupholder feature. (But so far the porch itself works fine)

Step 6: Fin

Before During After

Each chair was something like $41 for material not including screws, glue, and finishes and took approximately 4 hours to cut, assemble, and finish.

NERP Tonite: The New Raspberry Pi B+, and The BeagleBone eQEP

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.

Tonight at NERP, Craig LeMoyne will introduce the new Raspberry Pi Model B+: the new and improved version of the highly successful Model B. We will have a side by side comparison with the Model B and highlight the changes.

Servo motors are computer controllable motors that do pretty much the same thing as stepping motors. From a systems perspective they have nothing else in common. Servos use feedback to adjust the motor’s position and velocity. The difference between the target speed (or position) and the measured speed (or position) is called error. Without error, the motor has no reason to move. The type of sensor usually used to detect a motor’s position is called a quadrature encoder. Although servo systems can give better performance than steppers in some situations, servos are more complex and more expensive than steppers. Part of the complexity is reading and making sense of the encoder. Adafruit has posted a video in which Drew Fustini has a good job of introducing some techniques for accessing the special eQEP quadrature decoder module in the BeagleBone Black.

https://www.adafruit.com/blog/2014/07/15/how-to-read-the-position-of-a-rotary-encoder-connected-to-a-beagleboneblack-txinstruments-beagleboardorg/

A PS:One member (me) has a project that aims to use the BBB’s eQEP to control an Etch-a-Sketch. Tonight I’ll show some of the technology that’s involved and progress on assembling the system.

The Hackerboat Reborn

A couple of months ago, we revived an old project, the Hackerboat. The original project was building a boat to circumnavigate the globe autonomously. This was, to put it mildly, rather a bigger thing than we could chew. So the revival is a bit more modest in scope -- we're building an autonomous boat capable […]

South Shore Frolics Parade 2014

2014 South Shore Frolics Parade

Why yes, we did take part in the South Shore Frolics Parade this year, though we had a small crew, our small crew is quite dedicated… to having fun!

We managed to build a float to promote Maker Faire Milwaukee, and put Karen on a phone book so she could see where she was going, and we also convinced Chris to put the Makerspace flag on his bike and ride really fast so it would wave in the wind.

Shane let them know who we are this year by carrying the Makerspace banner, with what appeared to be great stoicism. And of course, there were some tiny electric vehicles from the Power Racing Series. Audrey on Lotusaurus Wrecks, Tiffany on Iron Rose, and I piloted the oldest still-running car we have, Baby Burrito. (Tom also tagged along and did some driving, some walking, and organized a few drag races!)

Thanks to the GoPro camera mounted on my head, we were able to capture some of the action during the parade. So enjoy the view from the top of my noggin!

Mike B’s Chair

Chair

We know you’re wondering what Mike B. has made recently. Well, he made this chair. And he liked it so much he made another one. Now he’s got two chairs like this sitting on his front porch.

What did you make this week?

MARRIED TO A MAKERSPACE GEEK

logo

 

I’ve known since I met my Makerspace Geek husband that he could fix ANYTHING. It didn’t always look pretty but it would work. I’m reminded DAILY just how talented he is. Unfortunately, over the years, being somewhat of a minimalist, I ran out of things to put on his Honey-Do List. I would find myself, at times, racking my brain trying to think of something he could fix or make. Because after completing a task and joyfully erasing it from the fix-it/make-it board, he was happy, contented and fulfilled. Lo and Behold he discovered Makerspace. I should celebrate the day as one would a major holiday. It has transformed my little geek into a big geek. He LOVES Makerspace and I love that he has a place to go where he can share, with other like-minded individuals, all the geeky thoughts spinning in his head. He still shares some of that with me but I know that oftentimes my head kind of goes on blank mode and I find myself just looking at him, trying not to nod off and listen. After his joining and I got over his starting every sentence with something about Makerspace, or his approaching total strangers and handing out a Makerspace card, or striking up conversations with family and friends and droning on for, what seemed like hours, about Makerspace, I surrendered. Why??? Because it makes him darn happy, that’s why. And who doesn’t want to see someone they love being happy??

 

So now when we’re eating dinner and I see him chomping at the bit because he wants to be at the club, I wish him well on his merry way and sit back to a quiet evening. If I’m awake when he gets home I get to hear all about the goings-on. I admit to crashing, often before he gets home because when he does he’s often so jazzed that I then have trouble falling to sleep .
Thanks, Makerspace, for making a space for him

The Internet’s Own Boy: The Story of Aaron Swartz

Come out to see the recently premiered documentary about the life and struggles of Aaron Swartz, Reddit co-founder and political activist.

From Wikipedia:

“Swartz was involved in the development of the web feed format RSS,[3] the organization Creative Commons,[4] the website framework web.py[5] and the social news site, Reddit, in which he became a partner after its merger with his company, Infogami.[i]

Swartz’s work also focused on sociology, civic awareness and activism.[6][7] He helped launch the Progressive Change Campaign Committee in 2009 to learn more about effective online activism. In 2010 he became a research fellow at Harvard University‘s Safra Research Lab on Institutional Corruption, directed by Lawrence Lessig.[8][9] He founded the online group Demand Progress, known for its campaign against the Stop Online Piracy Act.”
