Inspired by the knock to open hack, [ashish] put together a fairly simple DTMF decoder to control solenoid door unlocker and connected it to a Nokia 1100 cell phone. Call the phone, input the magic code, and the door unlocks.

(Page 1)2. Cool. Talk about a useful diy improvement. I think the creator/author of the device should patent it, if it's not already been patented, because this could make someone a fair amount of money, if it hasn't already.

6. #5: probably not all that farfetched of an idea. Though not sure about the stove in particular. But there are already IR controllers for lights/etc. Seems like it would be a short step to send the signal.
Good stuff!

7. There are all ready programs out for cell phones that will control your home computer like you were sitting in front of it. I wrote one in Java myself. This was two years ago.

8. The more things change, the more they remain the same. I rememeber seeing a project similar to this many years ago. It used the x10 home automation telephone decoder and appliance modules to control a solenoid door strike. If you lost/forgot your keys you simply called the automation from a neighbor's house or pay phone, turned on the particular module and the door unlocked. This was well before cell phones were widely known and before most people had answering machines.

9. #2, this kind of applications has been for sale for years, so this brings nothing new or worth of patenting.

10. For all you college students out there who have in-dorm landlines but never use them, just hook this up to your landline phone instead of a cellphone. Call your dorm to unlock the door, and you don't have to worry about wasting a cell phone.

12. How many of you have ever used those voice activated menus? The one for the US Post Office never worked for me until I started calling it all sorts of dirty names. Then it worked great.
That sure would be fun to hack as an add-on to this... "Open the **** **** door you ****!"

13. I'd like to have more than one device wired into this cellphone.
Then I could do other stuff like turn on/off my pc.
Quite a nice hack though.

My buddy Ray already has the patent on that, #5.

15. The terror boys in Baghdad have been doing this for years. Of course, they aren't unlocking doors when they dial their cell phones -- just blowing them up!

18. a hacker would not even have to brute force it if the lock picks up the tones let out loud by the phone just hide a recorder to capture the tones
