Since it will be outside 24/7, maybe we should install a weatherized
or skinnable keyboard? as if we dont, that may invite yet more keypad
fails down the road -

Actually we can just use a usb numpad if we want to keep it simple.
I actually I completely forgot, I got stole a usb 10key numpad from work
for this purpose. i'll try and bring it in this weekend, but that shouldn't
stop anyone from screwing a keyboard to the wall.
I'd also love to see the RFID working again, or atleast repurpuse that for
something else. It's just sitting there right now (if it's even still
there).

whoops, forgot to include niki
oh and to get into sudoor 192.168.1.42 (from the sudo network) you need to
have your key added by Jordan or William buddington. Or I guess i have
root, I can also do that if you send me your key.

Hello,
All of you receiving this want to breathe new life into the door.
Just to let you know, right now the raspberry pi that control the keypad
and the electronic latch mechanism, I set it to reboot itself every 4pm and
4am. That's been happening for the last few months.
My recommendation, without totally re-engineering it - which you are
welcome to do by the way - is this: Replace the keypad with a usb-keyboard.
Most of the errors come from the keypad disconnecting, not the uptime of
the Rasperrby pi. We know the pi is more stable than the keypad because
even when the keypad doesn't work, the web-interface unlock usually still
works.
Web interface unlock is a webserver running on "tamale" which is another
pi upstairs in sudo. And it calls the opendoor.py script which runs on the
downstairs doorpi, i call this pi "sudoor" by the way.
So. The quickest hack that i've been meaning to do for a while, is replace
the keypad, with a usb-keyboard.
That involves:
1. physical installation of a keyboard outside (screwing it to the wall
somehow)
2. tweaking the code baron.py in /root/sudoor/keypad/ (or some such on
sudoor) to take use the raw_input() command rather than the get_serial()
(because the keypad works over serial).
2.1 I also had this idea that we could use the caps lock key light as an
indicator, you can make it flash if the code is incorrect or whatever.
2.2 just thinking now too, if we use the raw_input() then we should also
catch the Keyboard_interrupt() exception and ignore it, so people can't
exit hte baron program cos they have the keyboard.
2,3 this will allow non numeric passwords if we want.
I don't mind consulting a bit, but my intentions have just been left for
too long, so ask me any questions you need, and be bold.

until we nail down the cause, if theres a usb power issue might a dumb
workaround be a scheduled power cycle every N hours? i.e., connect the pi
to an outlet timer..if we/anyone haz one of those to donate?
