Well, I finally finished documenting my latest creation:

https://www.avrfreaks.net/index.php?m...

This is the project folder, including a brief description. Photos of the complete device and a bit more instructions are on my site here: http://daqq.eu/index.php?show=pr...

This project is hereby released as opensource.

So:

The Concealed codelock (CC for short) is a design of mine, which can be used in a similar fashion as a safe lock, such as that on the picture above.

The rotation sensor used here is just a simple 10k potentiometer. The concealability in this is that you can use a double potentiometer. One part of the potentiometer will be used for the lock and the other one for something else, such as a amplifier, or any other normal home apliance that has a potentiometer for something.

Sweet! But, remember
No picture didn’t happen, can you post a picture of the dial at least and is it numbered A-D or what?
Good job,
John

Resistance is futile…… You will be compiled!

Keep in mind, that it is better to have the actual unlock
method to be separate from the user input area. Example: If doing a access control for a door, then the device that enters the unlock code is located on the non-secure side of whatever is keeping safe, and the actual unlocking device, say a relay output , will be on the secure side of the door .....
The unsecured side of the door may just send a code (SPI,TWI...) to the actual unlocking device.

I'll believe corporations
are people when Texas executes one.

It's more of a proof of concept device. Nothing meant for some high security systems :-D
