The goal of this project was to create an outlet which can be controlled over WiFi. The custom PCB converts 110VAC to 5VDC used to power the ESP12F, joins an access point and hosts an html page at a static IP address.
A 3D printed case was created in Solidworks by exporting the PCB as a DXF so that I could get perfect alignment of the mounting holes and push buttons.
A laser cut acrylic top and bottom add finishing touches to the design, both for safety and demonstration.
This design focuses on good practices like short return paths, avoiding ground bounce, appropriate use of the ground plane, and safe 110VAC isolation.
The board works as advertised and is able to switch a 5amp load safely. I have tested over the university wifi and have found it to work as expected.
