Small servo and simple build is great for beginners!
Who is there?
Not an intruder that’s who. Imagine a world where no one can easily open your door anymore. I traveled to the nearest locksmiths to create a kit that focused on door security.
While at the locksmith they challenged me that I couldn’t make a secure locking mechanism that WASN’T a key that could a hold door in place. Well, even though this could have been my imagination I challenged them!
Burglars no more! What you get out of this kit is the power to create your own rhythmic switch to make your door unlock. The rhythmic switch I use is the sound of a knock one makes when they… knock on a door.
In all seriousness I teamed up with two hardware and software engineers to accomplish this task. It took us a total of 2 months to finalize and complete the design.
You’re going to love it and make intruders second guess before breaking into your room.
