Hi Pete, This is a cool device! The design documentation is very comprehensive. Is the objective behind the wearable computer development is to manufacture and market it to pet owners? As Charles question in his post what is the piece price for the device?
I'd like to be clearer on the price I stated in my reply to Charles:
The $22 BOM price is the cost of buying the parts. That is an accurate estimate. I can't say what they would retail for, but typically, you would multiple by at least 8 for a product that does not yet have too much competition in the market place.
If the product is in a competitive product category, it may still cost at least 5 times the BOM price to the consumer if it is regarded as superior. The BOM cost of an iPhone 5 is $200, and it retails for almost 5 times that.
I would love to develop it into a product, but I don't have the resources to do so. I am happy to give free advice to anyone wanting to go ahead with it.
