I started working on the Pi-Lock the start of summer 2013. Presented with the problem of installing a security system in a factory for a low cost and high efficiency and overall control, I decided to opt for the Raspberry Pi and the infinite IO addons.
Here are the first pictures of what it the pi-lock looked like post summer development:
Photo of the side view. The Yellow and white wires are linking the Raspberry’s GPIO pins to the prototype board (purchased from Adafruit), for use with the RFID reader and LEDs.
Here’s a front view of the face of the Pi-Lock. Three LEDs, red, blue and green indicate various statuses, and a simple keypad is stuck on front of the face.
