Make: Live – Milwaukee Makerspace

Make: Live

It seems strange that it was just February that the Milwaukee Makerspace was finally settling into their new space and I stopped by to shoot a few photos. About two months after that they had their open house and now just two months after that we worked with Make: Live as part of the Hakerspace Roadshow.

I ended up talking with Matt from Make: Live about my Photo Booth project, and he pitched the idea of including the Milwaukee Makerspace in Make: Live’s Hakerspace Roadshow. The guys were more than happy to be a part of it, so we took it from there.

Make: Live

I did the camerawork, via the Logitech C910 connected to my MacBook and we did a test Skype call with Tim from The DHMN before Make: Live called us. The quality suffers a bit from the whole process, but it is a live show. It was challenging, but I think it turned out well.

Walking around with the MacBook, looking at the screen while the camera pointed outward was not easy. The image was flipped since Skype expects the camera to be facing you, not away from you. I don’t know if there’s some trick/hack for reversing the screen, but it would come in handy.

If you haven’t seen the video yet, check it out. It was also great to see the other spaces, Twin Cities Maker, i3Detroit, and Noisebridge. It was inspiring to see all the other space, and fun to work with Make: Live. I hope we can collaborate again in the future!

The Future of Open Source (Part II)

Open Source

In our first piece, The Future of Open Source, I talked a bit about hardware, and touched on community, as well as mentioned a few specific companies. This time I’ll talk about specific pieces of hardware.

Let’s start with the Arduino. The Arduino is probably the most successful piece of open hardware. There’s an estimate of 300,000 Arduinos “in the wild” as it were, and if that does not count “official” Arduinos, I can see that number easily being double.

Recently Phillip Torrone published an article titled: Why the Arduino Won and Why It’s Here to Stay:

While it’s nice that Arduino is open source, and commercial use is allowed if you make a clone, it’s not the biggest reason, which is why it’s down near the end of the list. However, that isn’t to say it doesn’t matter at all. Specialized derivatives can be made without paying someone or asking anyone. It’s open source hardware so a company or school can use it without any per-seat licensing. There’s no risk that it will be discontinued and the software gone forever. If you want a new feature, you can spend the time and get it added. When thousands of people have a small stake in something, or ownership, they care more. Does anyone even debate if open source software is a good idea any more?

I think part of the reason the Arduino (and its clones) have flourished is due to the community built around it. Thanks goes out to the people who are really into doing things with Arduinos, and sharing their work with others, and helping out on the forums, and teaching classes, and basically connecting with others and evangelizing the Arduino platform.

The first Arduino I purchased was the “official” Arduino Uno, which I acquired from Adafruit Industries. I remember finding out about Adafruit from the web site ladyada.net, run by Limor Fried (Lady Ada) who runs Adafruit. The fact that she had shared so many project details online led me to her business, and I became a customer. My Uno is what I consider my “top of the line” Arduino, and I feel pretty confident that it will work with any shield I get, not have any weird quirks to work around, and that buying it supported the Arduino project. Chances are when a new “official” version of the Arduino comes out, I’ll but that one as well.

I do have other Arduinos, like the Boarduino, also purchased from Adafruit. I wanted another Arduino, at a lower cost, that I could dedicate to a project. It fit the bill, and supporting Adafruit was something I felt good about doing. I’ve also got a Diavolino, from the folks at Evil Mad Scientist Laboratories. As I mentioned in my blog post, The Diavolino comes in at about $13—less than half the cost of an Uno—though there are some compromises with the Diavolino. If these compromises don’t affect you, it’s a nice little Arduino board. And as for the folks at Evil Mad Scientist Laboratories, they’re pretty awesome, just like Adafruit, and I feel good supporting them.

Now we move away from the US and over to China. I’ve got two “Seeeduinos” from Seeed Studio. I know some people would prefer not to buy from China, and if these were cheap knock-off products from a questionable company, I’d agree, but Seeed Studio seems to be a pretty well respected member of the open hardware community. They were a sponsor of Maker Faire, they helped with the radiation detection project after Japan’s Fukushima incident, and they actually develop a number of innovative products. If all they did was make a cheaper Arduino, I probably wouldn’t be as supportive of their efforts. As it is, I think they provide some friendly competition for others in the Arduino space, and do plenty of other things to be a good citizen of the open hardware community.

I’ve already mentioned the Evil Mad Scientist Laboratories gang, and their Diavolino, but I’ll also talk about the Egg-Bot. I bought the Egg-Bot kit because I think it’s awesome. Here’s the description of it: “The Eggbot is an open-source art robot that can draw on spherical or egg-shaped objects.” See? Awesome! (I’m sort of a fan of art robots.) Now, the Egg-Bot is awesome, but it’s an open & shared kind of awesome. Every time I demo it, I explain to people that it’s an open source device, and you can download the software for free, and you can download the plans to build your own for free. I’ve see a SphereBot, a Completely printable Eggbot, a Fischer Technik Eggbot, and an EggBot Makerbot Attachment over on Thingiverse, as well as many Egg-Bot design files. (Heck, you could even make an Egg-Bot out of LEGOs.)

The point of all this is, the Evil Mad Scientist guys aren’t out to crush anyone who tries to make an Egg-Bot… they encourage it. They’ve grown a community of users who help each other out, sharing what they’ve learned along the way. This helps make people fans of Evil Mad Scientist Laboratories, and the Egg-Bot, and be more willing to support their future endeavors.

But hardware, just like software, and life itself, is often a compromise, consisting of grey areas, like the Teensy. While I used a Teensy for The Button, and it was perfect for it, I still hope to move to an open source alternative if possible. I covered most of this in my Teensy vs. Atmega32u4 Breakout Board+ post. I’ll get my hands on an Atmega32u4 Breakout Board+ and see how it stacks up against the Teensy for future projects.

So where does that leave us, and the future of open source? Personally, I see open hardware as a choice sort of like buying food. You can choose to support companies you know, like, and trust, and you can even go to the local farmer’s market and talk to the people who make the food. I hate to use the word “sustainability” (only because I think it gets overused) but I think it fits. A sustainable future through open source. Works for me…

The Photo Booth

Last year I was invited to a co-worker’s wedding. And, since so many weddings nowadays involve being creative on a budget, they had a photo booth there that they set up themselves using Sparkbooth, a great little Adobe AIR-based application. A few weeks later we were having our annual work party, and I was tasked with making a photo booth a reality. Since then I’ve been working on building a better photo booth experience.

NOTE: Need a button? Now you can buy one! Visit our store or Etsy.

For the first one I set up, I used my MacBook Pro. We connected a Sony PD-150 video camera via FireWire and selected it in Sparkbooth rather than using the built-in iSight camera. (The iSight is a small camera, with a tiny lens, so the video camera ended up providing a better image.) We also put a little sticker on the space bar that said “PRESS HERE TO TAKE PHOTOS” and hoped for the best. It worked, but there were just too many moving parts to deal with, like the camera on a tripod behind the MacBook, and a light clamped onto the tripod. It wasn’t elegant.

The Sparkbooth software is great and provides a ton of features, including the ability to upload photos to Flickr, Facebook, Tumblr, Posterous, or a dozen other sites. There are some optional features that would require a keyboard—if you prompt people to enter their name, email, a comment, or choose if they want the image uploaded or not—but the main interaction is through pressing the space bar to start the picture-taking process.

If you need a space bar, you may need a keyboard… unless you build something that can emulate a space bar. When I saw The AWESOME Button on Make, I knew what I had to do. I had to build a button.

Ready for Pushing
The Button

The button is simple, and built into a metal case. It should stand up to abuse that a normal keyboard might not, and it’s pretty simple. You can’t really press the wrong button, there’s only one.

Once I had the button, I set about getting my old iMac set up as the photo booth machine. Not being happy with the built-in iSight (the iMac is about 4 years old, and it’s definitely not as good as the latest round of iSight cameras), I ended up taking the Canon ZR800 from Time Lapse Bot and using that. It worked OK but wasn’t ideal. I didn’t want to have to deal with a tripod and more cables, etc. (I even ended up testing a floor-mount camera holder I built which took pictures of shoes for a specific event—don’t ask!)

Ultimately I settled on using a Logitech HD Pro USB Webcam C910. Its image quality is much better than the iSight, and there’s just one cable to plug in. Just one problem… while it worked fine with my MacBook, no matter what I tried, I could not select it in Sparkbooth on the iMac. I tried everything, including different versions of Adobe AIR, different versions of Mac OS X, reformatting the drive, a clean install… nothing would work. I ended up disconnecting the built-in iSight thanks to some help from iFixIt.

The Photo Booth
The Completed Photo Booth

So I now had the button and the camera. I then needed something to hold it all together. I wanted a stand to put the iMac on that was about the right height for a “typical human being,” and by that I mean: about my height. (You can also easily adjust the camera by just tilting the iMac a bit.) I ended up building a simple pedestal out of plywood and painting it white. I used thin plywood to save on weight since it needs to be somewhat portable. You can’t see it in the photo but the back has been left open, and there’s an internal shelf for the keyboard and mouse. I keep those handy in case of trouble, or if I need to change any settings in the software. The shelf actually helps structurally as well.

For the light, I used a small IKEA clamp light (you’d be amazed how hard it is to find a small, good-looking clamp light.) There’s an L-shaped piece of plywood behind the iMac that’s held onto the stand with a c-clamp. It works for now. I may upgrade the light in the future.

Booth Photos
Photos from the Booth

Here’s a selection of photos from the first official use of the Photo Booth. (Yes, there are two Munchkins on the back wall—it was a “Wizard of Oz” themed party.) I’m asking for a bit of forgiveness in calling this a “Photo Booth” at this point because, while it does take photos, there isn’t an actual booth yet… I need to save something for Phase II of this project…

Stay Tuned!

Makey Birthday!

Makey Birthday

Hey folks, it’s a month out from my birthday (June 18th is the day!) and while I typically appreciate the gifts people buy for me, this year I want to make a request, and it goes like this:

1. Make me something!

Yeah, you (together with your own two hands) should make me something. Chance are you’re creative in some way. Maybe you can knit, or draw, or paint, or write a poem or a short story, or compose a song, or take an amazing photo, or maybe you are good with tools, can work with wood, can weld, or cut paper and glue it together, or maybe you make things in the kitchen, like lovely cakes or pizza pies.

If you need some inspiration, check out some of the stuff they highlight on Make, or check out the Flickr photos in the Make or Craft pool. If you really don’t think you can make something yourself, Etsy has things that other people make.

2. Give me money.

Yeah, those are the choices. Either you make me something, or just give me money. (Any amount is fine.) Seriously. Don’t go to the store and buy some mass-produced consumer good. Just make me something, or give me money. How simple is that?

Note #1: In the event you give me money instead of making me something, the money will be used to procure things like food or gasoline.

Note #2: In the event that I get awesome handmade gifts from people, I’ll blog about them, as long as people give me permission to do so.

Simple Sandbags

Typically when we do larger video shoots we hire a grip truck, and the grip truck is loaded with stands, and scrims, and lots of sandbags. Mmmmm, sandbags!

The sandbags are pretty nice. Thick canvas with strong handles, and pretty darn heavy. Of course if you make your own sandbags you can make them smaller and lighter, or bigger and heavier. Customize them as you wish!

Here’s my recipe for simple sandbags:

  • Sand
  • Plastic bags
  • An old pair of pants
  • Cord

It’s pretty simple really. Take a plastic bag, and put some sand in it. Tie it shut. Put it inside another plastic bag. (Try to get all the air out of it if possible.)

Once you have the plastic bag the size and weight you desire, find an old pair of pants. Cut the legs off. Make sure they are long enough to fit the plastic bag into.

Slide the bag inside the pant leg, and tie up the ends with some cord. That’s it.

Simple Sandbag

You could actually sew the ends shut, but then you need a sewing machine, and you need to know how to sew, and then these aren’t really “simple” sandbags anymore.

These also don’t have any handles, but again, we’ve kept it all pretty simple.

Simple Sandbag

Your new sandbags are now ready to hold your stands down, weight down your dolly, or be used as a makeshift cinesaddle.
