Tuxador

A simple, secure door entry/open counter.

Still in the planning phase.

Goals

• Make a basic, cost-effective counter
• Use an easy platform (this project will be used to teach)
• Support one doorway and a tamper switch, or two doorways
• Support proper security open/close/tamper/short loop
• Configurable ability to modify or reset the counter
• Indicate power on time, last tamper/short, last open
• All indications on inexpensive LCD display
• Directly mounts to common 16x2 character display or 1.8" Color LCD
• PCB design allows for destroying debugging interfaces
• 4-layer PCB, in cheap fab size, to bury any programming / debugging traces

What is this useful for?

Some potential uses of this project include:

• Secure doors or closets with internal access logs
• Door entry audible alarm
• Generic upcounter for anything one might use one for
