Math videos and math puzzle sculptures

While at Botacon 0 I had the singular pleasure of attending George Hart‘s presentation on “Cool Geometric Forms” and then actually meeting him afterward.  His mathematical and geometrical sculptures and puzzles are spectacular.  If you haven’t seen them, you really need to check out his website.  In any case, earlier this week I learned of a web video/blog series from someone named Vi Hart where the author would post videos of math doodles, puzzles, games, accompanied by whimsical and informative narration.

It wasn’t until I read her post about using a MakerBot for the second time, just this afternoon, that I realized that the father she referred to was none other than the George Hart I had met at Botacon.

I can only hope, that if I am a very very good father, teacher, role model, and example that one day someone will meet my daughter and then tell me what a wonderful/intelligent/witty person they think she is.  George, if you read this – you should feel as proud as I one day hope to be.

Happy Birthday to me!

On December 15, 2009 I purchased this domain name and started blogging about my MakerBot, “Bender.” 1

It has been a fun, wild year of blogging.  I started off pelting everyone on the MakerBot Operators’ group with questions, then started posting here a bit, then started posting here A LOT.

As I’ve mentioned, I don’t have any tech background at all.  I just try to make up for that with enthusiasm and a willingness to (let’s say, aptitude for) making a fool of myself.  I was gushing about 3D printing the other day and one of my co-workers asked why I don’t work in some some kind of tech field.  My response was that my real dream job would be to get paid to make and do cool, awesome, and clever things all the time.  2

I’ve had a really great time blogging here for the last year and over at MakerBot for the last three and a half months. 3  I get to write about all the stupid things I’ve done (and warn people how not to ) and the all awesome and cool things other people are doing.  The comments have been especially awesome – with people offering insight, advice, and <cringe> corrections. 4

So!  Thank you for your advice and suggestions and encouragement!  With a little luck, we’ll see another post like this next year!

  1. You may notice a few posts from just before that date.  That happened because I had originally purchased a different domain name and blogged there before settling on MakerBlock.com. []
  2. Mind, doing clever things is my dream job.  In reality, I’d try to do clever things and end up doing silly entertaining things. []
  3. I hope you’ve enjoyed it too! []
  4. It’s basically been my dream job.  :) []

Planning for time travel isn’t as easy as you might think

It is my intention to travel in time in about three days.  My plans are as follows:

On Thursday December 9, 2010 I plan to travel back in time 3 hours along my personal timeline.

On Sunday December 12, 2010 I shall travel forwards again by 3 hours.

Upon meeting people I shall declare unto them, “Lo!  I am from the future!  And it is a glimmering shiny place!  I cannot wait for you to see it!”

Help with the Disc Shooter?

The other day I sketched up a concept of a disc shooter – the style that used to be available in grocery store aisles at about my eye level.  Strangely enough I noticed over time they moved them lower and lower on the shelves until they stopped carrying them entirely.

In any case, I’d really like to print out an open source version of a disc shooter.  I was figuring that since we’re such good friends and all, you’d be willing to help out.  I’ve already gotten the ball rolling and posted my work designing the various components.

I realize this is a frivolous use of your time, but wouldn’t it be cool to be all “pew pew!” and then I’d be all “pew pew pew!” 1

  1. I want to print mine in clear PLA so I can see the bits inside working and the discs in fluorescent red so they’re easier to find. []

MakerBlock Testimonial from Les H

A few weeks ago I was contacted by Les H. about helping his company prototype a design.

Jay is very knowledgeable about his machine’s capabilities and any pitfalls.  His advice enabled us to get a pretty good first prototype out quickly, which showed some deficiencies in our design, and recommended changes to make the design more robust and enable his machine to print it easily.  We are about to make the second run.  Jay’s suggestions about wall thickness, design elements and dimensional requirements have made us pretty sure that this will be the one we use (unless I make a mistake on layout or measurements).  What he printed for us was exactly what we specified, and he worked with us to accomplish a moderately difficult design shape.  I am not a mechanical designer, so his assistance filled many gaps in my knowledge. Check out the photos.  It all fit together right the very first time.

My advice, go with Makerblock for your prototyping needs.

Regards,

Les H

They had originally expected to go through several design iterations before getting a usable prototype.  By exchanging a few e-mails and discussing their designs we were able to eliminate those intermediate print jobs.

Thanks Les!

Has anyone ever finished a printed chess set?

I’ve seen multiple chess pieces on Thingiverse, but I’ve never seen a full black and white (or any two-toned, for that matter) printed chess set.  Do you know if anyone has ever done this already?

I’ve got all 16 pieces in black ABS, but have been struggling with PLA.  Then, as I am wont to do, I’ve gotten distracted with this or that project.  I’m determined to print out all of the pieces in time for Botacon.  I’d really like to play a fellow MakerBot/RepRap operator with a totally printed set.  I’m less concerned the type of board we’re playing on – it could be a piece of fabric for all I care.
