Every time i check the site, they are out of stock

Awesome project, awesome watch platform.

wow, it is a really nice project, the only thing i’d change is the reed switch, i’d put it in the servo/pcb case to protect it..

but then you might need a stronger magnet. maybe a neodynium?

A little overkill unless you are Fort Knoxx. A little expensive as you better hope your watch lasts more than two years as I haven’t had one to last more than a few years.

Good project though…

Wow … This rules. TI really pulled something with their watch platform. I’m definitely getting one too !

@ Kirov , if you saw the movie you would have seen that you still can use you’re key in case of dead batteries or loss of watch .

@ClutchDude:

Sweet, I’m totally throwing that in with my next DigiKey order. Digikey.ca does the whole duties and taxes thing right on its site so we don’t have to pay UPS/FedEx/Canada Post their brokerage and handling fees.

Thanks for all the feedback guys. Glad my roommates and I aren’t the only ones who will be enjoying our door lock :)

You definitely can still use the door without power. In fact, we had to do this for a couple days during testing. However, you need to be careful and turn slowly, as you are turning the shaft of a high-torque servo as well as the lock.

@isama – Yes, we wanted to put the reed inside the box too, but it wasn’t possible with the magnets we had. I am considering some alternatives now, like better magnets or perhaps a plain ol’ switch.

The Chronos watch kit comes with a USB dongle that can communicate with the door. My next feature is going to be to design a web interface that can unlock my door from a remote computer (or my iTouch!)

We’re still in the process of refining our code and adding features, so stay tuned to Ziyan’s blog: http://ziyan.info

Very nice hack of the watch features, way to think outside the box using the accelerometer that way! This is also one of the few “dorm room lock” projects that actually involves a fair bit of security. Anyone could learn your knock or sniff a plaintext rfid message (someone sniffed my bus pass last year, luckily it was a buddy of mine) but very few people have ths particular watch and the message is also encrypted!

The only major change I would make is to have a mechanical lever or something to allow you to move the lock from the inside without opening the box if the power fails you.

This is a sweet hack and deserves the props! I hope to see more like it!

Great use of the watch. I like this idea much better than the finger print scanners or the normal RFID systems.

The first thing this reminded me of was the Spy in TF2.

Well is a nice project but what will happen if a thief steal ur watch or the battery of the watch go off? :) I will be locked outside my home ! :O
