hey... Hey!, HEY!!!, 1.1gr muscle wire actuator for under $10!?


Has anyone seen this before?.

For the people with experience with muscle wire actuators, what are your thoughts on it?
I've seen the datasheet but I couldn't tell if the contraction and release times are good or not.

In my previous job, I looked at something similar to replace solenoids in irrigation valve applications. The problem was the high power consumption. In this case, almost half an amp. Maybe, if they came up with a smaller, more efficient version, it could work.

I wonder if they were built with less output force, the cunsumption would go down right? do we really need 70 grams of force?

Ahh, the current. Somehow I overlooked that.
Still, it would be a nice thing to hack into.

But You would need 2 of these to go two ways from center right?

Thoughts of another one of their products. http://www.sparkfun.com/datasheets/R..._datasheet.pdf
1.2grams as is but it needs to be opened and a shaft added. Lightening oportunities maybe

I have a couple. Very slow compared to actuator.
