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
