ATtiny vs. Arduino Mini

Left: ATtiny (based on not having a Control module, instead wiring the button input directly to all ATtiny microcontrollers).
Right: Arduino Mini (it looks crazy, but it is actually quite straight fwd, and in my opinion simpler than the previous circuit i proposed.
We can “chalieplex” up to 8 * 7 = 56 lights – n*(n-1).
The sketch is a bit messy, but hopefully it makes a little bit of sense).

Summary

Notes

ATtiny microcontrollers with more in/out pins >> http://www.microfusion.de/e-/Microcontroller/AVR-Overview/ATtiny.html
issues:
– arduino programming supported?
– can microcontroller power more than 4 LEDs at one time anyway?

Bright Red SMD LED Options (for Rua’s Cape)

In order of appearance on fabric sample (see bellow):

365-1546-1-ND LED 0.33W RED WTR CLR 3.5MM – $0.43000 <-- this looks to be the best (and cheapest option!) for rua's cape

XPCRED-L1-0000-00401CT-ND LED RED XLAMP CLR SMD – $2.44000

67-1345-1-ND LED 3X2.5MM SUP RED CLR CERM SMD – $1.28000

475-1315-1-ND LED TOPLED ADV 625NM RED 6PLCC – $1.12000

1080-1259-1-ND LED SHUEN 1W HI POWER RED SMD – $3.53000

LEDs not featured on above sample:

160-1506-ND LED 7.6MM SQ ALINGAP RED CLEAR – $0.53800 <-- this looks to be the best (and cheapest option!) for rua's awakening flowers

TLWR7600-ND LED TELUX 4PIN RED 2100MLM – $0.55000

365-1392-1-ND LED RED WATER CLEAR 6MM SMD 0 1.91000 $1.91

Awakening flowers by night:

Pickable flower by day, and night:

Testing software PWM on ATtiny85:

In the script there are three or four scenes in which flowers are picked. Only in one of the scenes does it explicitly mention that the flower lights up as soon as hemming picks it (this is when he is recalling how he met pali). Could also add a pressure sensor to the stem, so that the more it is squeezed the brighter it gets.

How should these flowers should look? simple/extravagant, real/futuristic, natural/industrial….? Sketches for a set of three different looking flowers that all light up as soon as they are picked (the stem is touched). As they are held, their light(s) starts to pulse. for the pickable flowers i will use RGB LEDs, meaning that they can also change colour to white/orange/yellow/gold and red.
In addition to having the flower light up as soon as they are picked, i am trying to make one of the flowers open up using nitinol wire (a shape memory alloy), similar to this example >> http://vimeo.com/18650899

Photos of scene:

Rua will have to trigger the lights on her cape, once to indicate the arousal cycle, and then again once she has come, to start dimming the lights. her cape could have a tie or clasp on it that she opens/closes naturally as part of the scene and also works as a trigger event.
another idea would be to have a pressure sensor attached to rua’s cape, so that the harder she squeezes the more arousal she indicates. the pressure sensor could be flat and in the hem of the cape, or it could be something like this pompom pressure sensor >> http://www.flickr.com/photos/plusea/4953569835/
(to simplify things, one idea i had was that the lights in rua’s cape don’t light up individually, but rather pulse (dim and brighten) together, and the flowers surrounding her are the lights that light up individually.)
