CNC Hip-Hop

CHC Hip-Hop

I don’t know if the Maker Movement has any hip-hop artists in its ranks, but at some point someone is going to want to write a rap mentioning CNC machines, so I’ve compiled a list of suitable rhymes for “CNC” and I present them here.

Note that some of these words/phrases are serious, and some of them are just for fun. It takes all kinds.

  • Jamboree (fun word)
  • Wait and see (should be in reference to the time it takes to finish a job)
  • Filigree (should be in reference to detailed artwork.)
  • My man Adrian B (should be in reference to Adrian Bowyer of the RepRap movement.)
  • Look good to me! (should be in reference to how a job turned out.)
  • Jubilee (fun word)
  • My main man Bre (should be in reference to Bre Pettis of MakerBot)
  • Bumblebee (fun word)
  • Bruce Lee (fun, but could also be in reference to strength/power.)
  • Guarantee (fun word, but could also be used in reference to how a job turns out.)
  • Tree (should be in reference to the consumable used for a job is wood, which comes from trees.)
  • Billy D[ee] (should be in reference to Billy Dee Williams or the other Billy D)
  • Whiskey (fun word, but you should think twice before combining alcohol with any power tools.)
  • Debris (should be in reference to the scraps/waste left after a cutting job is finished.)
  • Banshee (fun word)
  • Emcee [MC] (this one is obvious, I should hope.)
  • Waikiki (fun word, possibly only suitable for Jerry Isdale.)
  • Potpourri (fun word)

Alright! That should be enough to get started… can you think of any more?

Art Robots [video]

Art Robot

Here’s a video I put together to show how two of my art robots function. The video is playing right now in the gallery where some of the art is on display, as I mentioned previously.

You can do a lot with an Arduino, two servos, and a few other miscellaneous parts. ;)

Buy my thing! (But not from me?)

GoPro $$$

This is an interesting one, and I’m still not sure what I think about it…

I’ll start by saying that I’m a fan of open in that the sharing of knowledge is important to me, as is the sharing of sources, not just in software, but in other areas as well. Yes, there’s money to be made, but generally, besides the fact that money allows us to have a place to live, and food to eat, and all the other things needed to survive, I’m not really a fan. Money itself is boring, but it can allow you to do interesting things.

I recently posted about the GoPro Hero3 Frame I made. I made it because it was a thing I needed, and didn’t feel like spending $40 on the nice one that GoPro sells. I shared the design files because I thought they might be useful to others. I share things because I’ve gotten so much value out of others sharing things over the years. It’s been over 20 years that I’ve tried to live by that ideal. It mostly works.

I was quite pleased to see that someone found value in my sharing, and improved upon my design to create GoPro Hero3 Frame – Improved. Again, this is how I want the world to work. I made a thing, and someone else made it better. Everyone wins, right?

So anyway, I’m doing the daily browse, and I come across this blog post from Shapeways titled 3D Printed Stand for the OP-1 Synthesizer. I have little interest in a synthesizer stand, but I love 3D printing, and think it’s the future. In the post is a link to all the GoPro items on Shapeways. (Shapeways, for those who don’t know, lets people design things, get them 3D printed for themselves, and even sell them to others. It’s a great thing for people who don’t yet have a 3D printer, or want higher quality, or different materials, etc.)

Shapeways

Where was I? Oh yes, I click on the link to see the GoPro related items and see a GoPro Hero3 Frame and think “Hey! Someone else made one too! Cool!” and I read the text, and it sounds just like mine! Now, it was about 4am so my brain was a little slow… but I clicked on the link…

Shapeways

Holy Crap, that is mine! Yeah, that’s mine. And it’s for sale, but not by me. Here’s where you decide whether to freak out… and to what degree.

Now, I designed my item, and shared it freely on Thingiverse, and even used a Creative Commons Attribution License. I specifically wanted others to be able to have it. Mission accomplished, right? Right.

So the freakout… is it a good freakout, or a bad freakout, or a weird mixture? Do I want to be in the business of selling GoPro Hero3 Frames? Probably not. I have enough other business to deal with, and as I said, GoPro sells one, and it’s probably of much higher quality. Am I upset that someone is using my work? I shouldn’t be (right?) The description does say “Created by Raster” and has the URL (but not a link) the the Thingiverse page. But who is cadbury204? They have no designs of their own in their Shapeways shop. Is it some automated bot that pulls items from Thingiverse and sells them on Shapeways? I don’t know… if it is, does that change things? I don’t know…

If I think about the “spirit” of open source, as it’s ofter referred to, is this “cadbury204” following it? Are they providing value just by allowing someone to easily order the item through Shapeways? Are they just out to make money from the work of others? Again, I don’t know… I don’t even know if I should care, but I guess I do, mainly because I find it interesting.

And, I’m interested to hear what you think about it.

Plastic Sun on Lake Effect

Lake Effect

Remember last year when the Chipstone Foundation issued the Tool at Hand Challenge and I created a piece called Plastic Sun? Well, during the event I was interviewed by WUWM and the story aired on Lake Effect this past weekend.

You can check out the archive and if you want to hear my segment, here’s an MP3.

Enjoy!

The Making of MAKE

One of the great things about Milwaukee Makerspace is the inspiration you get from other people. Kevin recently used our aluminum forge to create a piece he calls FEAR, which he said was an update of Robert Indiana’s LOVE.

I’m not one to give in to fear, and I figured that with a new year beginning we should focus on something a bit more positive, so I created MAKE.

I also figured I’d walk through the process of creating this piece.

MAKE in Inkscape

While MAKE is three dimensional, it’s really just an extruded two dimensional form (sometimes called 2.5 dimensional) so I started as I often do, with Inkscape. I used Georgia Bold, which is the font Kevin used in his piece, and typed up the letters for MAKE.

MAKE outlined

I selected each letter and combined them into one object via the “Union” command under the “Path” menu.

MAKE outlines joined

At this point we no longer have editable text but an outlined object. We still have curved lines though, and that just won’t do for 3D printing, as we need all straight line segments.

MAKE with straight lines

I selected all of the segments and inserted new nodes. Once you have more nodes, you can convert all of the segments into straight lines. No more curves! If you add enough nodes the short straight line segments will look like a proper curve. (Adding more segments can increase the complexity of the file, which can increase the time to process and print it, so don’t go too crazy.)

MAKE reversed

After I had my artwork outlined, I exported it as a DXF file and brought it into OpenSCAD to extrude it. Also, here’s a trick: I actually flipped it 180 degrees in OpenSCAD so that it would face down on the print bed. I wanted the “front” of the piece nice and smooth.

MAKE

Here’s what it looks like in proper perspective… What’s that? You’re already getting inspired to make something? Excellent!

MAKE in plastic

And here’s our final piece. MAKE… in plastic… for your desktop. I like the white, but I definitely need to get more filament colors… I think this would look great in orange or red!

MAKE it BIGGER

I made an attempt at a larger version, but the old RepRap went a little crazy and the print failed about 15% into it. Still, it’s a pretty good MAKE if you ask me. Perhaps this one is more suitable for the wall than the desk.

(Note: grab the file from Printables.)
