A WIFI based solution would be much better for easy access to the home/network ecosystem Using an accurate RTC like DS3231 and Wifi chip ESP8266, a PCB was fabricated. Also there was a need to make a good case to host the electronics. Acrylic case making is cheaper as compared to 3d printing. Found an enterprising acrylic fabricator who made an amazing case. The power supply was embedded in the back of the case so it could be directly plugged into the wall socket or the ESP8266's USB power connector provided for at the side of the casing.

Teeny space in the WebVerse to shamelessly brag (document) about things that were attempted, things that worked and that did not, both in the professional and hobby fronts. Topics include hacking, modding, new ideas/ways of doing things in many domains (electronics hardware/software, making stuff, mechanical, etc). Maybe to inspire, learn, ignore or forget. It might not work for you. Try at your own risk. Thank you for stopping by and would be delighted to hear from you.
