Designing the Absurd

Remote-controlled Device

Ideation

We initially had a few ideas:

After discussing further we decided to go with a whole new idea,

Technical Stuff

Upon making the IR sender and receiver work, I decided to implement it using two Attiny 85 microcontrollers to save space. It is powerful enough to do what we want and it makes the circuit so much simpler and smaller.

We decided to use an electromagnetic module and attach a metal piece to the door so that it can be held in place and when a button is pushed the module will lose its magnetic field for a few seconds so that the door can be opened.

We 3D modeled and printed a container for the button to be in the proper height and also we have the curved edges to lead the ball towards the hole.
