Is there any way that if a person takes the outside box apart they can open the door? (Without the RFID tag that is), or is it only the antenna of the reader in the box? (and the LED)
Looks nice, simple to use and effective.I like the RGB LED too. I think it is much neater than having 3 seperate LEDs...I like the programming card but not so sure about the eraser card. I suppose if you have a small number of people then it'll be good SmileyIs there any way that if a person takes the outside box apart they can open the door?

What happens when power is out - can you still operate the door using a regular key with and without power?
At the very last of the movie, a box mounted on the wall inside is shown, and text saying that it houses the arduino.So I guess that it is only the reader and led in the outside box
The "outside box" was a blessing. I had no idea what I was going to use to water proof this thing outside. I was at my local home improvement store and just wandered the aisles until this thing popped up in front of my. its a "weather proof gang box" Its intended use is put it over an electrical outlet outside of your home. Once I had all the components inside and had it all working correctly I siliconed the box shut. So I could get it open if I had to, but at the same time...its shut really well - and completely rain proof.
Well I presumed that it was just the reader and the LED but if someone got into it could they send serial down one of the wires or something to get it to open. I presume even if this is the case you would need to know the code to be able to send it so you might as well program your own card.I presume from this analysis, there is no way someone can electrically 'brute force' open the door that you know of by using the connections that there are outside.
The lock itself is activated trough a solenoid, right?I wonder what'd happen if someone put a really high voltage trough it. Would it blow the entire system up? Would it unlock the door somehow? Or nothing would happen?
Yes if some one opened the outside box and somehow manipulated the rfid reader and figured out which pin was the rx and then some how hooked up to that and then spoof a valid RFID tag that I have in the system...they could gain entry... I suppose...
and also some sort of logging to see time stamps and cards coming and going.
The next things I would like to add are both lock out times E.G. - card1 only opens the door from 7am-11pm. So card1 could never open the door at 2am.
SD would be good or maybe an ethernet shield, external logging and access. Maybe some kind of remote locking/unlocking.Someone rings you up cos they don't have a card, you then open the door remotely. Maybe have a network webcam set up on the control page too.
