hexacon. well, hexapod jewelry and then someday a post about hexacon

i wanted to make jewelry
i also need prizes for saturday’s hexacon
hexacon2013.mit.edu

bought some supplies from http://www.yelp.com/biz/artist-and-craftsman-supply-cambridge, then lasercut some hexapods from a vector SVG file of my hexapod CAD files

I added some lock washers and made them asymmetrical, because I miss the ones that +Hanna Lin made for me a while back that look like this, but prettier and more functional.

Fatal flaw of acrylic jewelry: it only wants to face one direction, sideways, by default (I twisted it around to take this picture). Ah well. A puntly-hour’s worth of work.

  1. hexacon
    Hexapod conference funded by deFlorez humor fund! Been doing a lot of work refining the vision of the conference/convention and how to make it humorous and yet useful to attend at the same time.

    It will be like academic conference – hexapod dance off – giant hexapods – poster session and the humor will come out of the contrast.

    Hexacon!

    The lifecycle goes like this:
    – Pick a picture from the Android photo album
    – Run a Canny edge-finder on it to get to a black bitmap with white lines on the edges of the original picture. I used a splendid implementation by Tom Gibara– Run a vectoriser on that, to generate vectors along those lines. I couldn’t find one I liked, so I write one, which was easier that I expected.
    – Simplify the vectors – discard very short vectors, and replace straightish bits with straight lines. The Arduino can only store 300 points, so we have a strong incentive to optimise the vectors to within an inch of their lives.
    – Package the vectors up and send them over Bluetooth to the Arduino
    – Wait for the drawing ! 

    For speed, I’m working with very low-resolution bitmaps – 128 pixels square by default.

Hexapod conference? how to plan a conference budget?

caution: hexapods ahead. cc0

I applied to the deFlorez Fund for Humor at MIT. The application deadline for grants over $1000 was due at midnight, and at around 10pm I decided to apply for funds for a hexapod conference.

I should hear back by the end of MIT spring break (the 30th).

Funding decisions will be made approximately two weeks following the application deadline. If an award is made, disbursement of the award will take place once sufficient funds have been secured to hold the event.

 If they fund this, it will be hilariously awesome. However, the application is so hilariously rushed and badly written that I am actually really embarrassed. It was so much fun writing it though. The coherent parts were written by the lovely +Julia Hopkins (http://fluidarchive.blogspot.com/), including this beautiful part:

Please explain in one or two paragraphs how exactly this event fits the de Florez Humor Fund mission of “impressing students with the importance of humor in all aspects of life, both personal and business.”

Let’s face it. An MIT student’s personal life is their work life. Too few are prepared to find the humor in this, or prepared to acknowledge such humor exists. This conference epitomizes silliness in research, silliness in personal projects, and silliness in how we envision the technical world around us evolving. Moreover, it highlights the importance of this silliness in a student’s daily life. The concept of a hexapod, the concept of investing time and resources into something that, in the end, probably won’t change the world (unless you build it several stories tall and figure out how to give it a Godzilla complex), resonates with many an MIT student. This conference is to help them both acknowledge and celebrate all of the things in their research, classes, personal lives (for those that persist in imagining they have one, in any case), and business which have not gone the direction they anticipated, or which did not provide as much of an impactful result as they were envisioning.

I would try and explain the humor of wrapping all of this up in a metaphor of hexapods and then go on to wax eloquently (or perhaps just wax) about the philosophical implications of how a project which has gone nowhere can still impart necessary skills and life lessons, but that’d be spoiling the fun of it. You should come see for yourself the wonders of dancing hexapods, the hours of toil put into this utterly silly contraption, and experience your nervous laughter as this parody evolves into genuine humor acknowledging all of the ridiculous things humans do which, somehow, make the world a better place. We’re just not sure how yet.

Well, anyway.  How do you plan a conference?

Well, you decide on a mission (yes, conferences have missions) and then make a budget. This is a most excellent guide on missions and general conference thoughts: http://ctb.ku.edu/en/tablecontents/sub_section_main_125.aspx

e.g.

 The field needs a conference.  There are several possible reasons for this:
  • The field may be a new one, and still lack a clear identity.  A conference could bring together the people who are building it, and help to define it.
  • The field may not be cohesive.  People in it may not know one another, may disagree on methods or other issues, or may simply not realize how many others have similar interests.  A conference could bring them together and create networks that would expand and improve the work.

The mission of this conference would be to promote silliness at MIT.

Here is the budget I ended up with:

.
Item Cost Comments
.
venue rental fee connections (held in the N52 IDC space, using equpiment there)
.
food and beverage fee 300 (can be acquired from dumpsters but kind of sketchy)
.
transportation & lodging scholarships 500 to help people make it here
.
A&V, recording, livecasting equipment 150
.
speaker fee bribe with cookies
.
activity fee 100 (lasercut hexapod material – bristol board)
.
miscellaneous fee 100
.
prizes from reuse
.
.
Total 1150

(budget table in neater formatting here)

And here is my (rambling because I had no time) proposal:
https://docs.google.com/document/d/1rq3cIFy9j1FjbIYA67gpZCksZKgtXzLZrxkLw93_v2s/edit

The conference schedule (tentatively planned for May 4th) would be

9 – 9:30 registration, breakfast
9:30 – 10 keynote speaker
10:15 – 11:15, break, 11:30 – 12 five-minute lightning talks (+ 5 minutes questions), nine total
12 – 13 eat food and make hexapods (invite general public, including kids)
13 – 14 hexapod dance-off, other hexapod competitions (e.g. fastest?)
14 – 17 conference talks about specific topics (e.g. the use of hexapods in educational kits, in adaptive terrain traversing (climbing trees, over rough ground), in millirobotics)
17 – 18 pm Poster session and demonstrations, appetizers
