Here is my project DRS4Baby Powered by amazon DRS..
Objective of this project is to design Low cost Solution for Amazon DRS based end products.. as a complete end to end solution with multiple slot use case.. This project uses cheap ESP8266 (<3$ ) which handles all Amazon DRS End Point APIs.. My product Registration webpage is based on simple java script for LWA process hosted on my blog http://drs4baby.blogspot.in/2016/11/registration.html ..
Your suggestions, Questions and Critics are welcome for this project.. I havent found a way to write blog here so posted as Question..
