Ideas: PoV Yoyo, Press-fit food || Classes, Spring 2011

Mmmmm.... classes.
Started out with:
2.008 (Make a yoyo)
6.131 (Power electronics)
6.042 (Math for CS majors)
6.003 (Signals and Systems)
6.004 (Computation Structures)
Some HASS class

Now:
2.008 (Make a LED persistence of vision yoyo)
6.131 (Power electronics)
MAS.863 (How to make almost anything)
21M.611 (Foundations of Theater)
Possibly either 6.003 or 6.004, still.

In other words, I was ecstatic when I heard I got into MAS.863 and that flipped me in favor of not double-majoring in 2 and 6 (unless I decide to take an extra semester or something).

==mas.863==
Our first assignment:

• design, make, and document a press-fit construction kit http://academy.cba.mit.edu/classes/computer_cutting/index.html

Trying to think of interesting new ideas, I thought of pressfitting food (sparked by my interest in etching poptarts for nyancat poptart). The hunt for a suitable material is on...

Other materials guy: http://web.mit.edu/bin/cgicso?options=general&query=bredt came up with powder solution for 3d printing

(Other people's projects, which overlapped with some of my other ideas:

• animal figurines http://fab.cba.mit.edu/classes/MIT/863.10/people/Sarah.Hirschman/02cutters.html

===2.008===

In the meantime, I've also been ignoring the present day and contemplating the near future of 2.008. I think we're supposed to be making paperweight designs or something, but my partner is a but hard to contact, so I've fallen back on daydreaming about LED persistence-of-vision yoyo's. Doesn't seem to have been done already, surprisitngly. And now for linkspam research:

PoV
Other products

• $5.16 PoV Fan http://www.dealextreme.com/p/customizable-text-handheld-led-message-display-cooling-fan-gadget-3-aa-17850

• Looks a lot like this other fan featured on hackaday:

• Teardown: http://hackingwithgum.com/2009/10/06/hacking-the-cenzic-pov-fan/
• large chip is the EEPROM (type of memory), with 4 pin headers to read/write
• there must be a sensor (hall effect sensor? it's a DC motor) in the circuit somewhere, but not easily discernible (perhaps it's covered by epoxy?)
• I only have one so I haven't taken apart my own fan yet
• $35 PoV Top (Luminodisc) http://www.gizmine.com/gzar/luminodisc.shtml

• No teardowns available on the web, no cheap Chinese knockoffs either (and this is from 2009)
• Nice closeup vid: http://www.youtube.com/watch?v=UDzsrCLxPb8

RFID tags idea: oohh, someone in a previous 863 class had a similar idea for not forgetting things. Or rather, exact 

same idea! Haha. http://fab.cba.mit.edu/classes/MIT/863.08/people/nadya/week1.html
