System Integration¶

In my system integration page, I will be documenting how I brought the hardware, electronics, and the software together, and make them work together as one functional system.

Cardbox prototype¶

Our instructor made us make a carbox prototype of our final project. This activity was very (emphasis on ‘very’) helpful to us. It made us think about where we were going to mount all out electronics and how they were going to be connected to eachother.

This is how mine turned out after HOURS of hardwork.

This is when I open the door to the box. The small hole in the front is for the electromagnets to lock the door. As you can see there are 6 compartments for each iPad.

Here is a clearer view of the inside of the compartment. I have made a smaller compartment under each space for the iPads to place my pressure sensor which leads to the back of the box, for good wiring.

This is the top of the box where I will be mounting my electromagnets and RFID reader.

This is the hidden compartment where I will be placing my extension cord to charge the iPads and mounting the microcontrollers in.

CAD design¶

After I was done with the design of the enclosure, legs, and slots for the solenoids, I moved on to making a more precise CAD design by bringing all my components together. You can click here to get more details on my designing process.

I used GRABCAD to add models of my electronics to my design. To learn how to use it, go through my documentation by clicking here.

Here are details on my final CAD design after I was done assembling it.

Electronics holder¶

To properly hold my electronics in place and make my system more ogranized, I made sure to assign a specific place in my box for all my components by designing and 3D printing a holder for each one of them.

I have hyperlinked the fusion files to my fusion at the end of this page

Assembly¶

Now that we are mostly done with the electronics and the designing and fabrication of the physical components, we can bring them together!

I drilled the legs I printed into my enclosure.

NOTE: The door hinges will be store bought and I initially planned on using screws to attach the metal plates(therefore, the holes) but due to the lack of time and a flaw in the design(the metal wouldn’t attach properly to the magnet after using screws), I decided to just use super glue instead. So kids, always make sure to think again and again about your design plans and assembly it as quick as possible so that you spot those mistakes early on.

I then added the door with the hinges. I attached the metal plates I have designed specifically for the electromagents to stick onto to my door in the perfect position so that it attachs properly.

Here is a picture of me assembling it.
