The Arc-O-Matic Drawing Machine

Arc-O-Matic

Once again Gallery Night was a blast… This time myself and the Milwaukee Makerspace guys joined forces with Bucketworks and showed the art-lovers of Milwaukee what we do. (Make things!)

Since both Drawbots were busy at the Art Milwaukee Wedding event, I needed something new to show. (And yes, I did say “both” because there are now two rolling drawbots.)

Anyway, I saw this blog post over a year ago, and made a mental note to explore the idea more, and I did, and the result is the Arc-O-Matic: a robotic drawing arm that makes arcs. Well, that’s basically what it does at this point. See the Arc-O-Matic project page for all the details.

People seem to really like seeing machines that draw, which means I’ll probably keep on exploring the world of art robots.

File Under: FUN.

(Also, if anyone knows who I can talk to at Sharpie about a sponsorship, I’d appreciate it!)

Robot Art

So what did I do at DrawCamp? Well, I had the Friday Night Drawbot working hard at creating some drawings, and here they are for you to enjoy!

Friday Night Drawbot v3

Friday Night Drawbot

You may be familiar with our Friday Night Drawbot from back when it was at Version 1. Well, we’re now at Version 3, and there’s been much improvement. With Version 2 we made the body a bit shorter to get a tighter turn radius, and we’ve continued that trend with the latest revision.

We’ve also switched to AA rechargeable batteries, so no more disposable 9 volts. This means that we can use our eneloops and since we’ve got a dozen of them, we can run all day and switch them out as needed.

We’re also using a Diavolino from Evil Mad Scientist Laboratories now, which means we can use a shield, which means we’ve cleaned things up a bit as far as the wiring. The “brains” are also detachable from the rest of the body now. Speaking of the body, we’ve rebuilt that as well, and used hot glue and velcro in place of duct tape and rubber bands, so things are a lot more secure. (Don’t worry, there’s still gaff tape and rubber bands, but it’s much cleaner now.)

Friday Night Drawbot

Keep an eye out for the Friday Night Drawbot at the next event that somehow manages to blend art and technology…. or something like that.

(Oh, I’ll also be adding a bunch more info on the Friday Night Drawbot project page.)

Milwaukee Makerspace Grand Opening Recap

Grand Opening

The Milwaukee Makerspace Grand Opening & Mini Maker Fair was held on Saturday, April 9th, 2011 and wow, what an event it was! The photo above should give you a little indication of the crowd. It was “several hundred people” from the estimates I heard…

I’m mainly going to talk about my own experience, since I really didn’t get to experience much of the event, which is sad, and weird, but also cool.

So, I got there around 10am and Matt was heard to say “Hey look, Pete brought BarCamp!” due to the amount of stuff I tend to bring with me, including projects to show, camera equipment, tripods, audio equipment, projector, tables, Time Lapse Bot, and other things. I got set up at a table and put out my projects. As usual, I was way too ambitious, and actually pulled back and didn’t show everything. This was a good decision, as there was just too much going on. The two projects that got the most interest were the Egg-Bot and the Friday Night Drawbot.

The Egg-Bot is just, well, it’s just cool. I had to explain a number of times that I did not “invent” it, but I built it from a kit. I gave a brief explanation of it (including open source software/hardware, Inkscape, etc.) to a lot of people. One kid was interested in it, and I told him how much the kit cost, and then he complained it was too much. I then described the parts used to construct it, and as soon as I said “laser cut” he was like “oh, yeah, laser cut, OK!” and then he was sold, and thought it was something he should have. (I did point out that it was all open source and he was welcome to get all the parts and assemble his own.)

Eggs

I ended up printing about 50 eggs throughout the day, pretty much non-stop. I ended up doing someone’s name on an egg, and then printing one with the word “VEGAN” on it, and then at some point a mom asked if I could print a monkey. A monkey!? Well, off to OpenClipArt.org to find a monkey. And a candy cane. And a rose. And a cat. And the Rebel Alliance logo… I somehow ended up being a one-off egg printing factory! (But it was a lot of fun, and I learned a lot more about Inkscape.)

We gave away a lot of eggs, and I (mostly) remembered to tell people they were raw eggs, and advised the kids not to squeeze them, put them in their pockets, or drop the on the car ride home. One very young girl suggested I should have got up earlier that day (maybe 4am) so I could have boiled them all. As my excuse, I told people it would be easier to preserve them by blowing out the insides since they were raw. One woman gave us a dollar for an egg. (We added it to the Makerspace Donation bucket.)

Drawbot Action

And what would the day have been without some Drawbot action!?

I don’t know, but I do know I’m lucky Sam showed up and took on a lot of the Drawbot maintenance. He also ended up exploring Drawbot in ways I haven’t yet, using the Ultra Fine Point Sharpies, and the results were pretty darn good. I’ll try to scan some of the drawing this week. I’ve also got some reprogramming of Drawbot I want to do soon.

Oh, and I ended up telling a lot of people about the Arduino, and how the Drawbot worked, and explained that it was pretty darn easy to build, and if they came down to the Makerspace on a Thursday night, someone could probably help them get started with Arduino hacking.

Now, as for the rest of the event… I missed most of it! I was at my table for nearly 8 hours straight, with just a few quick bathroom breaks here and there while Sam watched the table. I think I need a “Back in 10 minutes!” sign or something. But really, it was a blast talking to so many people and answering questions… but it was also exhausting. I didn’t feel comfortable enough to just leave the table unattended for any large amount of time, so I’m not sure what the solution is… except to have someone else work the table along with me.

I have almost no photos to share from the event, and no video (except for the stuff Time Lapse Bot shot) so head over to the Flickr pool to see some more photos.

Oh, and word from the makers is that they all loved it, it was a great/successful event, and they can’t wait to do it again. Well, they can wait about a year maybe. :)

Sharpie Conditions

Drawbot Crazified

After I made the Friday Night Drawbot I told the folks at Sharpie about it, and they posted it on their blog.

The only problem was, I read their Terms and Conditions, and was unable to agree to all of them…

I figured I had a few options, either submit my post, and just ignore the wording of the Terms and Conditions, not submit my post at all (and I have done this in the past, given up on things due to the ToS, etc.) or I could submit it, but add a disclaimer… I opted for the disclaimer.

Terms and Conditions

I built a Drawbot that uses Sharpie Markers. (A Drawbot is a robot that can draw pictures)

Please note that in your Terms and Conditions I cannot agree to 3. B. (“each and every element of the Submission is an original work created by you” I used ideas that others have had, and code others have written. Drawbots have been around for many, many years. Open source hardware, and software, were used which were not created by me. I did however, write the post, and take all the photos. That work is all of my own.)

There was no way I could accept “every element of the Submission is an original work created by me” when I used other people’s code, other people’s ideas, and hardware that other people designed and built. Sharpie’s Terms and Conditions are not bad in any way, they just make it harder to take into account the culture of sharing that exists nowadays. I mean, lawyers like to see things in black and white, but there’s a whole lot of gray being created lately.

So the next time you’re confronted with an agreement, and a text box, let them know what you can and cannot agree with.

Also, I’d like to thank Sharpie for posting submission, even with the “disclaimer” I added to the description. I’m assuming most people don’t have an issue with the Terms and Conditions. I am not most people, obviously.
