device which detects the shape (movement) of an animal, and plays a sound, and rotates an object


i want a device which detects the shape (movement) of an animal ( see : [login to view URL] )

and plays a sound (for example : the barking of a dog)

and rotates an object (for example : a thin (3-5mm), light, plank (wood or plastic), which has the shape (outline) of a dog)

if possible, the animal must be detected at 360°, if not, back and front (90°90°), and then the object must rotate towards where the shape was detected

the device must work in winter conditions (around -15C, with wind, rain, snow, frost)

the device must work independantly and be portable (powered by a battery and a small photovoltaic panel ?)

ideally i must be able to tweak the detection sensivity (distance of shape, size of shape), the kind of sound played, the volume of the sound, in which condition the device should play the sound / rotate the object (for example once every xseconds)

maybe play a sound randomly, from a list of sounds (so that i can decide which to use depending on its effectiveness to scare these animals...)

work description :

->design the circuit, design the code (using arduino board?), suggest the parts to use

->note : you only have to work on the circuit design and code, i will buy / make the parts (shape of the dog, roof/box for the device).

->test it until it works well on your side

->send me the schematic of the circuit, and the code to control the board, and instructions to assemble the circuit / code / parts

->give me a list of components / parts to buy (preferably in the same webshop to reduce shipping fees, also preferably with fast delivery (not months !))

->once i have received all the components / parts, i will assemble it on my side and test it

->once the device works as described, the work will be considered finished and i will release the milestones

->at the end, i will create another milestone to pay your freelancer fees. (5USD per milestone ?).

->there is no time constraint to complete this project, as long as we make regular progress and that you answer my questions / requests fast enough.

->concerning the amounts of the milestones, there will be one of 100EUR at the start, and depending on how it goes and what you need (as long as it is reasonable), i will add others.

(nothing is fixed, let's discuss of what is possible or not...)

Thanks for your help,


about the shape / weight of the object to rotate :
i think that it would be better if it is very light, so it could be a statue made of expanding foam (painted), or something similar to a kite (with a light plastic skeleton and a thin plastic (painted) fixed on the skeleton)

the goal is to give the illusion of a scary dog (or of a scary predator) with a (painted) shape and a sound...

finally i want a simpler version of the device :
one or several motion detectors, which can detect a big shape ( human / deer ) which triggers a sound (barking of a dog) and 2 lights (LED)
then we may improve / add others functionalities to the device.
