Spring Gallery Night 2012

Spring Gallery Night 2012

I’ll be joining my fellow makers from Milwaukee Makerspace for Spring Gallery Night this Friday, April 20th, 2012 at the World Famous Bucketworks in Milwaukee, Wisconsin…

The last month or so has been crazy-busy, and it’s been difficult to find the time to work on a project, and I ended up shelving a few ideas and building something I’ve wanted to build for the last two years or so. It’s another drawing machine… sort of. It’s still very much in-progress, but you can stop by and check it out (along with much cooler stuff from some of my friends.)

Arc-O-Matic 328

ArtWorks for Milwaukee will also be there, and they do some great work with Milwaukee-area youths, so even if you don’t like our crazy mix of art, technology, noise, and robots, come on down and show your support for the ArtWorks crew.

Skill Badges (Part II)

Welcome to Part II of my self-awarded skill badges! (See Part I for background.)

Speaking of badges, there’s been some talk of badge systems, and some hackerspace/makerspace things happening where we might get to the point of awarding badges to members, maybe using Les Orchard’s Badger code, or maybe something else. It’s in the works… that’s all I can say right now. (And that’s pretty cool, right!?)

Programming

Programming: I will award myself the Programming badge based on the fact that I’ve gone from BASIC in the 1980s to Perl in the 1990s to PHP in the 2000s and Processing in the 2010s. That’s like 30 years of programming!


QR code

QR code: Flags on cupcakes for Bay View Gallery Night at Milwaukee Makerspace last year… Done!


Robotics

Robotics: I’ll pitch Friday Night Drawbot for this one… Some of the other things I build have bot in the name, but this might be the only true robot. (Plus, I just built a second Drawbot.)


Soldering

Soldering: Heck yes to soldering! I first learned to solder when I was a teenager, and I did take electronics classes in high school. I’ve learned in the last two years though that my technique was crap. No matter, it’s much improved lately. I’m only doing through-hole stuff, but I think that counts.


Welding

Welding: This one is questionable. I did a bit of welding at a demo we had at Milwaukee Makerspace, but I’m still not at the point where I could do it all on my own. I should do more welding this year…

Skill Badges

I decided to award myself some badges, I mean, no one else is gonna do it, right? Badges? Badges! Yeah, all those awesome badges you’ll find over at Adafruitthose badges.

And, no, I’m not the first to show some badges, and hopefully not the last either. At Milwaukee Makerspace we often refer to ourselves as “Skill Collectors” so these badges fit in nicely with that idea.

3D Printing

3D Printing: I think I’ve earned this one. While it’s true my RepRap is only (about) 80% done, I’ve managed to tame the MakerBot CupCake we have at Milwaukee Makerspace.


Bike Repair

Bike Repair: As a kid I used to fix my bike all the time. Also, when I was in college I managed to rescue a bike from a dumpster behind a frat house in Madison and re-built it into a completely usable ride.


Catapult

Catapult: I seem to remember building a small catapult out of scrap wood and rubber bands when I was a kid. I’m pretty sure I scared the cat with it. (Since I have no photographic evidence I should probably try to earn this one again.)


Circuit bender

Circuit bender: I supposed I did do this thing… but let’s be honest, that was pretty simple, and again, I should do much better to earn this badge.


Drawdio!

Drawdio!: I have built a Drawdio! I wasn’t really happy with it though, and I want to rebuild it into another device, but that’s a project for another time.


Dumspter Diving

Dumpster Diving: I’d actually have a sash full of these. Besides the bike I mentioned above, things I’ve gotten from dumpsters include: stereos, books, money, a photocopier, food, clothing, tools, and on and on and… I’ll stop before I embarrass my family any more.


(ESD) Electrostatic discharge

ESD (Electrostatic discharge): Have you ever grounded yourself by touching something metal before installing something new inside your computer? In the olden days when I had a Macintosh IIvx I used to put on rubber soled shoes, attached a wrist strap and treat RAM like it was highly explosive. Of course nowadays I install new RAM while eating pizza and sipping whiskey. (RAM also costs about 1/10 what it did back then.)


Hacked Kinect

Hacked Kinect: All I’ve got so far is that we did some 3D scanning of heads at Milwaukee Makerspace, and then reduced the complexity of the models, and 3D printed one of them. (It’s a work in progress.)


HTML 5

HTML 5: I’ve built more than one thing using HTML 5. The first one was probably the Evil-O-Mator.


Lasers

Lasers: Although it’s been a learning process, I’m getting good results from the Laser Cutter now.


LEDs

LEDs: I’ve definitely done projects with LEDs. My CheerLight is one of them.


Linux

Linux: Although it took me a few years to get into Linux, I now own about 3 Linux machines and administer 5 more. I like Linux. (Well, for servers anyway.)


Magic Blue Smoke

Magic Blue Smoke: Sadly, I have released the Magic Blue Smoke at lease once… and at least once it wasn’t my own equipment. Oops!


Metric System

Metric System: Ah, the good old Metric System! I really didn’t use it much until recently. Working in the RepRap world, and with the laser cutter, and other hacker/maker things, I’m starting to get used to it. (Sort of.)


Micro-controllers

Micro-controllers: Do Arduinos count? Does the Teensy count? Then yeah, I got this one…


Multimeter

Multimeter: I probably first used a multimeter in 1986, and while I still have a lot to learn about them, I can handle the basics, so that’s something.


Whew, I didn’t realize there were so many badges!

That said, I’m going to break this post into two parts, and I’ll cover the rest of my skills (or lack of skills) in the next post…

Laser. Cut. Wood. (Part II)

Laser Cut Box

In our last adventure cutting wood we had success! And it was good… So I decided to try the awesome BoxMaker again and I’m pleased with the result as compared to the previous attempt.

Above you’ll see the template I created from BoxMaker with a light bulb on one of the faces. I got the original bulb from OpenClipArt and tweaked the SVG file in Inkscape until I was pleased with it. (I may still need to adjust a few of the thinner areas, but I definitely like it.)

Bulb Box

In the next image you can see the results of the cut. This is using 3mm Baltic Birch plywood, which I highly recommend for the 25 Watt Laser Cutter that Milwaukee Makerspace has.

There’s actually one extra piece in the lower center which you’ll notice has straight lines, and is not part of the box, but this is the interesting part…

One thing about using the laser cutter is determining what settings to use. For this cut I used 100% power with 3.2% speed. It takes a few passes to complete the cut (maybe 4 or 5) but it works. I found that at slower speeds there is a higher risk of flames (which are bad!) and you can char the wood a bit too much. I actually didn’t care about the charring as I will be painting this box, but if you want less charring, up the speed a little bit, and know that you will need more passes.

Burninator

Oh yeah, the interesting part! In the image above, I’ve highlighted two areas. In the bottom red rectangle you’ll see a lot more charring. This is due to the long straight line that the laser cutter follows when cutting. I noticed that the notched areas, with lots of small short lines, had much less flame, while the long continuous lines had a lot more flame. (It was still within an acceptable amount of flame, but this is why I didn’t want to go lower than 3.2% for the speed.)

So I’m definitely calling this one a success, if only due to the fact that I’m pretty certain I’ve got good settings to use when cutting 3mm Baltic Birch plywood.

Also, lasers are awesome!

CNC Control Panel Progress

It’s a known problem that I take on too many projects, and that tends to make some of them drag out longer than they should… has it really been more than a month since I started this one?

Yes it has. In my UI Mockup/Diagram Apps post, I was working on a control panel for the CNC Router we have at the Milwaukee Makerspace.

First Attempt

The image above was my first attempt to hack something together. I wanted to do a layout with paper to get a good idea of the physical size of things. As you may notice, the buttons are big, and make the whole thing fairly large. Larger than I wanted. So through a few posts I connected with a fellow maker in Madison who offered me some smaller buttons…

Control Panel

Once I had the smaller buttons, I sat down with some paper and the calipers, and started measuring things, and making the new layout. These were, like the previous attempt, just some rough sketches on paper. Once my paper sketches were done, I moved on to Inkscape, and made the digital version of my control panel.

Paper Mockups

I then went back to paper, by printing out my files, to get a feel for the size and spacing of everything. I didn’t go as far as mocking up an actual 3D model, though it would have been easy with some foamcore or matte board, but it’s one more step to take if needed.

Cut Panel

And as long as I was at the makerspace for some laser-related shenanigans, I figured I’d cut a test of the control panel using acrylic. (I’d like the final done in wood, but I had some scrap clear acrylic on hand, and it’s easier/faster to cut than wood.)

As is often the case, I screwed up one bit of the file, and the lower-left cut is too large. The two holes on the right are waiting for buttons I don’t have yet. Right, make that: buttons I didn’t have yet. More buttons showed up, but they are slightly smaller, so I’ll meed to re-size things again before the next cut. Back to the old drawing application, as they say.

And hey, I better finish this project soon, because there’s talk of adding a 4th and 5th axis to the router! I don’t really mind though, because so far I’ve really enjoyed the process, and I’ve learned a lot along the way, so even if this thing is outdated by the time I finish it, I’ll just start on an upgrade. :)
