All things MakerBlock: RepRap, MakerBot, Cupcake CNC, open source, and plastic building toys!

Men just don’t understand…

So, let’s say I was a tinkerer1 and you told me that you could show me a robot that could make things out of plastic that I would normally have to cobble together out of junk.  I would say that is awesome.

During the most recent Ask An Engineer Woz was2 talking about her knitting machine.  LIGHT BULB.

Honey!  Honey!  Guess what?!   Did you know there are such things as KNITTING MACHINES!?!  I mean, ROBOTS that would do all that tedious knitting FOR you!  We could just program it and it would just make stuff for us!  Isn’t this awesome?!  <Wait for squeals of glee>

.

…

Apparently there’s something about the act of knitting that is considered productive.  I don’t know.  I’m not convinced.

Isn’t humankind just all leading up to the point that we’re all like the Jetsons and I have a robot at work that pushes the single button for me.3 And jetpacks.  Can’t forget the jetpacks.

Where was I?

Oh, knitting robots.  Okay, here’s the thing – I may not be interested in knitting, but a knitting robot interests me. 4 5  I am not interested in knitting something myself any more than I am interested in actually building something layer by layer with a hot glue gun that shoots molten ABS. 6  But, I am interested in having plastic stuff just as I’m interested in having clothing.

Heck, if I had a super big and super fast knitting robot, I’d probably try to weave paper or cardboard into clothing and then wear it and then try to recycle it into something else. 789 1011

Also, this is what I believe a knitting robot would look like:

  1. which I am [↩]
  2. Was she? [↩]
  3. Reminds me of an old joke about a man and a dog and a data center.  Supposedly you only need one of each to run a data center.  The man to feed the dog and the dog to make sure the man doesn’t touch any buttons. [↩]
  4. Then again, a robot anything interest me. [↩]
  5. A robot carrot, you say?  Tell me more! [↩]
  6. I take that back.  Now that I think about it, a molten plastic gun might be kinda cool.  Bad analogy.  That’s not the point. [↩]
  7. And, I’d be all, *clap* *clap* Knitting Robot!  OoooooooooHHHhhhhhh Knitting Roooooobot!  Knit me a pony Knitting Robot. [↩]
  8. That pony doesn’t look happy enough.  Destroy that pony Knitting Robot.  Make me a HAPPY pony! [↩]
  9. Oh, this one is too happy.  Destroy this pony Knitting Robot.  Knitting Robot…  destroy all ponies. [↩]
  10. Knitting Robot, are you crying? [↩]
  11. Thanks to Dna for the link! [↩]

Love the smell of burning wood in the morning…

I just added a Relay Board Mounting Kit to my Cupcake.  It’s been a few months since I’ve assembled something from a laser cut kit, so having that now-familiar smell of burnt wood, ash, and singed adhesive…  Ah!  That takes me back to when I first assembled my Cupcake!

Anyhow, up until this morning1 my Relay Board was hanging off the side of my Cupcake by the very wires it was connected to.  In order to prevent it from shorting anything I had wrapped it in the anti-static plastic my circuit boards came in and then used electrical tape to seal it all up.  Not the best way to do things and certainly enough to prove the world at large that I’m NOT an electrical engineer…2

  1. It’s very very early or very very late, depending upon your perspective [↩]
  2. Like I had trouble convincing people before… [↩]

Creating an Online Profileinator

I’m always juggling multiple projects – that seems to be the mark of a Maker and/or a Maker with ADD. 1  I’m looking to tinker with a clockwork spider, an open source disc shooter, possibly an open source shooter compatible with Nerf darts, and now…  I’d like to create a web app that aids in the calculation of good profile settings.

I’ve downloaded a bunch of different Thing-O-Matic, Cupcake, PWM and RMP calculators off of Thingiverse and am tinkering with them to get a better understanding of how they run these calculations. 2  Once I understand these, I’d like to make a very simple front end for these calculations.

If you have a good idea of how these things work, please leave a comment or shoot me an e-mail through the contact form.  Thanks!

  1. Which, in my experience, might just be a redundant statement [↩]
  2. I’ve put out the call to Dave Durant to help me get a better grasp on these calculations… [↩]

Don’t think I’ve given up…

Just because I didn’t label the Clockwork Spider on Thingiverse as a “work in progress,” don’t think I’ve given up on it.  It exists now as an actual physically printed object and I’m very happy about that.  However, the legs are just a stand-in1 for nice spidery looking legs I’ve already designed.  There’s no point in printing the real legs up until I’ve gotten a mechanism that will make them work.

  1. As it were [↩]

I’m 7 for 7 on the Thing-A-Day challenge.  I originally didn’t think I’d be able to do this – making something new each day.  However, I’m dusting off old things that I haven’t uploaded yet, designing new things in OpenSCAD as tests and proofs of concepts as part of my research for upcoming tutorials, and it now seems very manageable.  In fact, I’ve build up a small reserve of things I haven’t had to tap into yet.

Robotics Work Area

My work area
My robotics work area

I thought people might be interested in seeing what my robot work area looks like. 1  Part of this last weekend was devoted to organizing the contents of the above library card catalog, putting things in appropriate drawers and labeling them. 2

You can’t really tell from the photo, but each of the Three-Dee printing ‘bots is sitting on a separate filament spindle kit.  I’ve got clear MakerBot PLA loaded underneath the Thing-O-Matic (“Flexo”) and black MakerBot ABS loaded under the Cupcake CNC (“Bender”).3 On the surface of the card catalog you can see a pink bracket I printed for my daughter so we can hang a bathroom towel4 at her level.  I’ve got a power strip duct taped down to the back left of the card catalog.  This has made the entire thing the perfect stand-up computing and soldering station.5

The drawer labels are difficult to read from that image – in large part because of my tragically terrible handwriting. 6  In case you’re interested, the highlights are:

  • Two different drawers labeled, “GLOWSTICKS”
  • One drawer labeled, “GLASSES”
  • One drawer labeled and filled with “NOTEBOOKS”7
  • One for “SPEAKER BADGES” of various kinds.  Admittedly, most are just from attending different conferences.  About a third are from when I was speaking at such conferences.
  • One drawer labeled and filled with various kinds of “TAPE”
  • One for “ORIGAMI” with paper and half-completed projects
  • One for “SANDPAPER” of differing grades
  • One drawer for “CABLES” and one for “USB CABLES”

I’m probably using almost 30 drawers, which is only half the front side of this library card catalog.  It’s got 60 such drawers on the front and back. 8 910  This monster occupies what was originally called a “living room.”  Now we just call it our “robot room.”  I was lobbing to change the name to either “The Robotics Lab,” “The Lah-BOHR-Ah-tory,” or the “Laboratory” but the idea did not receive the required 67% of household votes.

The way that I look at it – I could quadruple my robotics hobby and still have enough drawers for it all…

  1. It’s a bit messy, but worlds better than before I tidied it up. [↩]
  2. I had posted a description a while back, but this probably explains it all much better. [↩]
  3. FYI, Flexo has a small magnet installed behind the front panel.  That way I can affix a detachable magnetic soul patch. [↩]
  4. What color do you want, honey?  “Pink, PINK!”  *sigh* Now, if ONLY we had a robot that could make a pink towel hook for you…  “Daddy, stop being silly.  Of course we do!” [↩]
  5. I use a long wooden tray when I solder or assemble something with small fiddly bits.  That way if I drop something it falls into the tray. [↩]
  6. If anything, the JPG compression probably helps the readability. [↩]
  7. Including my DIY homebrew recycled paper and shopping bag analog notebook [↩]
  8. The sad part is this thing is SO huge and SO heavy that if we move, we’ll never be able to take it with us. [↩]
  9. It took an unreal amount of fuel, beer, and pizza to move it to where it is today. [↩]
  10. If you live in the Bay Area and are interested in it – drop me a line. [↩]
