View source for Project:Tool Access Control/ACNode-cl

== Objective ==
* Get an reduced functionality acnode out there ASAP and add improvements incrementally as they are developed/needed.
* Have a platform that's fexible enough to do other things (power metering, display driving, etc)

== Updates ==

* 5-OCT-2014: Switching to a PN532 chipset reader, had to write a library for energia. issue with not enough current to drive the SSR relay being looked into by tgreer
* 12-AUG-2014: Problem discovered with support for mifare classic cards (old oyster, barclaycard)
* 11-AUG-2014: Ready for integration with the Lulzbot

== Specs ==

Minimal implemnentation.

Based on:
* TI Connected Launchpad ~ £15
* <s>RC522</s>PN532 chipset ~ £10
* Solid state relays for equipment control ~ £2 
* uln2003 Darlington array or similar to switch 5V from Connect Launchpad for relay ~ priceless

Cost: <£30
