I think we are getting close to a functional beta of handyLock. handyLock is a Mac OS X application that allow you to lock your Mac when you move away from it. It use an Bluetooth device as a proximity keycard or card to accomplish this a no cost.

It is working pretty well on my side and I have not received much negative feedback so I think it is doing pretty good.

Features implemented so far are?

• Sensitivity gage to tune when the screen will lock to your specific Mac, Bluetooth device and environment.
• Application specific display sleep configuration to set how quickly the screen should blank out when away. Range from 1 minute to 3 hours
• Basic signal processing algorithm that should minimize inadvertent screen lock in case of Bluetooth interferences when you are working at your Mac
• Ability to hide/show Application Preference windows when it start
• Ability to add the application to the Login Items so it start when you login to your account
• Safety PIN in case the screen is locked and your Bluetooth device is not working. This will unlock the screen and turn the application OFF until you are ready to turn it back ON.

What is left to do?

• Provide a gage to tune the sensitivity to degraded Bluetooth signal when you work on your Mac
• Improve signal processing algorithm
• Implement other user suggested features
