Homemade door opener and monitor

Interesting build, the author built his own arduino based board for it too.  I like the build but…it looks like its just a basic back and forth over bluetooth to open/close the door (not very secure). http://www.instructables.com/id/Bluetooth-Door-Opener-Monitor/

Add Spritz encryption to your Arduino

I have heard of the encryption method before.  Don’t know much else beyond that.  It sounds promising but I wonder how much space it takes up on the arduino.  And how fast it is. http://hackaday.com/2015/12/12/encryption-for-arduino-with-spritz/
