Today I’m going to teach you how I design and built the “ULTIMATE ELECTRONIC DOOR LOCK” follow me on this step by step tutorial, I’ll explain every detail and trouble I had during the construction.
I hope you enjoy it!
As you can see in the picture above the case its made by 3 different pieces, the cover with a simple circular design, behind a 3mm acrilic sheet and at the end the box that contains everithing in it.
Oh, almost forgot it, I will put this device INSIDE a door, not on either side, so… it will sit flush with the door face.”
