The Door Lock

To make the wooden clasp that will keep the door locked, I first started sketching what I think the clasp should look like.

After I sketched out the clasp, I traced one of the four drawings out onto a piece of wood.

When I finished tracing my drawing onto a piece of wood, I cut out the tracing with a dremal cutting tool.



Proof of Concept

For my project I plan to attach a micro-servo to a slide lock, and mount it on my door as a locking mechanism. To move the slide lock back and forth, I will use a finger scanner to lock and unlock the door.

Proof of Concept

For phase one of my project, before I involve the fingerprint scanner, I will make the door locking circuit work. To achieve this I will need a servo to rotate the slider lock, a slider lock that the servo will move, and finally some AWG wire.


For my project I want an easy way to lock and unlock my bedroom door. The main reason I think this would be a useful investment, is simply because of the lack of keys we have for our doors. We literally only have one key, and that one key is the hardest thing in the world to use. Because our doors are so old, the doorknobs are super wobbly and the key-unlocking mechanism is loose. However, with this fingerprint scanner I will have the capability to lock and unlock my door with the greatest of ease and precision. So that, summed up in a paragraph, is the reason I would like to make a biometric fingerprint scanner.
