solar panel layout + power specs
9 April 2012
Layout for the solar paneling – black lines are the structure of the petal (wood, aluminum, brass, or carbon fiber TBD), white lines are the solar panels.
The power specs are in yellow on the second drawing.
initial data logging from the solar panel
9 April 2012
Gabriella Levine has beautifully set up an arduino data-logging circuit for the powerfilm solar panel we’re looking at:

a real-time visualization of one solar panel’s voltage at no load is here
petal motion test #2
9 April 2012
Second motion prototype for the petal mechanism. And stapling little bits of rubberband to cardboard is much harder than it looks.
synth tests, round 2
27 February 2012
two prototypes, one with two piezo speakers (and no power supply), and one with two small speakers (with a regular power supply)
and here’s a model for what it’ll look like physically:
first digital squeezebox test
13 February 2012
first prototype for a battery-less synthesizer – either a crank-powered electronic music box or a digital accordian.
bridge rectifier example

this is from a VAWT wind turbine Dustyn Roberts and I built (it uses a stepper with two rectifiers):
