this is some what of a question or challenge and if the answer to this is align with our thoughts it will be a job offer. We would like to develop AS SMALL AS POSSIBLE (Question 1: How small can it be?) device which is possible to communicate with from a phone in a as effective and cheap way as possible (Question 2: What communication system is to be used?). On a given request, no matter where the application is, from a phone this device shall give a sound and or a buzz (and should be able to make two different ones). And then to some more questions. Question 3: How long will a battery last? Question 4: What could the estimated price to the consumer on mass production be?
Hope to find some answers and also a good freelancer to hire.
