«Let's open the door by using overcomplicated solutions.»

"Unknown" is not in the list of possible values (Meeting, Workshop, Talk, Slacking, Conference, Hacking) for this property.

Notepad :


You are outside, you have a key for the door of the space but no fancy-schmansy garage port opener.

Expected outcome: the door opens.


Day 1

stuff that happened

  • A huawei dongle that catches incoming numbers with a python script (see Joren's blogpost)
  • Research on the build of the remote, conclusion: "not that simple", result : get a relay over the buttons powered by arduino.
  • Made schematics for arduino
  • An asterisk server that also fetches phonecalls but probably won't be used in this project.

the gameplan

Discussion in the end gave us some idea on architecture:

  • Beagle board
  • Usb hub
    • Huawei dongle
    • Usb wifi key / or usb network card
    • Arduino -> Relay -> dooropener


  • one utp cable running from space to appt in front.
  • one remote we can hack
  • server running in the space
  • Random electronics (including an arduino)


  • Be able to open door by using wifi
  • Be able to open door via the interwebs
  • Be able to open the door with your cell phone.
  • If possible: not necessary to leave a pentium running all the time (power)



  • Main chip : XE34AB / NICE FRO1

(can't seem to google it... maybe bad eyes)

  • The small 8-pin DIP labelled "93LC46" is a 1K EEPROM manufactured by Microchip. (datasheet)
