Very pretty. Awesome application.A couple of questions. Does it matter what the rating of the LDR is? and it looks like you are using a total of 8 batteries is that correct or are there only 4?
A piezo wing flapper and a 555/boost power supply?
Maybe the solution was overkill, but the firsts usually are. As a unique wedding day touch, it was top drawer! Congrats, maker; best wishes, bride & groom.
This is a neat project indeed. My guess is a small gearmotor, although I can think of a couple of ways to do it using a small motor similar to the vibration motor in a pager. Then a PWM drive to slow it down, and it is done, except if it needs to be checking for movement to tigger the motion.
But this project could indeed be the start of another fad.
He purchased the butterfly as seen in the photos, I'm not sure what the wings are made of but it looks like some fairly thin cloth/nylon/spandex type material. In the Instructable he says that the wings will be finished in fabric that matches the dress.
A moving mechanical butterfly in your hair would really turn some heads. It seems that DelFly is on to something similar although they could use some tips in making their ornithopters more "butterfly" looking. And, of course, remove the camera as well. Getting it to alight on top of the brides hair whilst in the course of reciting her vows would also get a few "wows".
Some of this technology has been perfected and mass marketed in the RC helicopter and airplane world. Minature recievers, lithum ion batteries, tiny servos made from motors and a leadscrew occuping less than 1/2 of a CC. The green led in this case tells the operator that the system is powered and ready. I would have modified a Ready to fly Blade MCX which costs $135 and includes a co-axial 4 channel helicopter, 4 channel radio, battery and charger...
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
