All things MakerBot! MakerBots, RepRap, and robots!

MOAR CUPCAKES! Or, am I being a glutton?

Posted on by

MakerBot just announced they’re dropping the price on the MakerBot Cupcake CNC Ultimate kits to a ridiculously low $455.00.

I already own a Cupcake CNC, named “Bender.”  He’s been fully upgraded with an automated build platform, MK5, and a few printed upgrades as well.  (Right now it has a Unicorn instead of the MK5 installed.)  I already own a Thing-O-Matic, named “Flexo.”  My Thing-O-Matic is fully upgraded with a MK6 stepper extruder and a few minor printed upgrades.

Do I really need more plastic printing production capacity?  I don’t know.  Do I have a new name for a potential new robot lined up?  No, I really don’t.

Do I really want another 3-axis CNC robot?  Yes.  Yes, I do.

Back from Maker Faire SF Bay Area 2011!

I’m exhausted! 1  What a great time!

I got to spend time with my family, see some amazing stuff, meet some great people, and see some old friends.  I also ate some junk food!  Perfect weekend all around.

I got to meet several people for the first time – including beak90, DocProfSky, DNA.  A few people mentioned they liked my OpenSCAD tutorials, which just made my day.

  1. So exhausted I didn’t get to publish this post until just now… [↩]

Pick me! Pick me!

Okay, I’ve gotten the clearance from Pattywac to join in the United We Stand team design challenge.  Although I voluntarily take myself out of the running from every challenge, I love participating.  They’re just too much damn fun.  :)

I never participate in the judging on these things – but it would look a little odd to have me be both someone who blogs about something and a guy who is the subject of the blog post.  Blogging here at MakerBlock.com, I happily post about anything that comes to mind, even if it is ridiculously self-indulgent.  However, I really don’t want the posts at MakerBot to be about me – I want them to be about the awesome stuff people are doing in the DIY 3D printing community.

The potentially ethical problem I faced with this most recent challenge is that as a team design challenge, I wouldn’t want to disqualify an entire team of people just because I was on it. 1  So, my proposal to MakerBot and Pattywac was that as part of any team, I would agree to forgo any winnings of any kind. 2  This was acceptable to both.

So, are you interested in collaborating on this design challenge?  I’d be especially interested in getting collaborative help on any of my existing projects, going from my highest interest3 to lower interest4 :

  1. Clockwork spider5
  2. Open source disc shooter
  3. A printable clock that actually keeps time
  4. A sonic screwdriver
  5. A dalek that can rotate it’s head, roll, and move it’s gun, eyestalk, and plunger6
  6. A better Voltron
  7. A puzzle box
  1. And, really, having me on your team is hindrance enough. [↩]
  2. I just want to feel included! [↩]
  3. #1 [↩]
  4. #7 [↩]
  5. I’ve already had input and help from Dna on this [↩]
  6. Mad props to innovationbylayers for the existing dalek on Thingiverse [↩]

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…

Posted on by

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

Creating an Online Profileinator

Posted on by

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.
