|Unlocking a Combination Lock
Using a Stepper Motor
In this project you will use a stepper motor to unlock a standard combination lock. The power of this project is that it uses an old computer such as a 286, 386, or 486 and a few parts that should cost less than $5.00.
Instead of building from scratch I have repurposed one of the robots from my previous robotics project. You can read up on that project here.
|How-To the Build Unlocking Device|
|Instructions||An overview and description of how to build the unlocking device.|
|Schematics and Drawings||An electronic schematic of the device. This is a repurposing of the robotics schematic.|
|Pictures||Pictures, showing the device connected to a lock including a video of it working.|
|The Software||This is the software used. The complete annotated source code is provided as well as a executable copy. It's very alpha but it demonstrates the basic concept.|
