Week 5 - Journal

For this week's assignment, Simple device was required to be built and simulated using TinkerCad, In a blazing hot weather I could think of nothing but a cold glass of water and imagining as if a cold breeze is passing by 🫠.

That was when it hit me, "Make a Fan", So I decided to build a simple desk fan.

Using TinkerCad:

1. All components were inserted, (DC Fan: the main purpose of the device is to cool down the area around it, LEDs to show that the device is ON and resistors for safety.)

2. Power Supply (supposed to simulate the 5v adaptor) was set (5V,2A), as DC fan require 5V to operate effectively.

3. Components were connected in such a way that illustrates which side in positive and which is negative ( Red +ve, Black -ve).

4. Made sure that the fan and LEDs are connected in parallel, then started the simulation to ensure no components will be damaged

1. The circuit was built according to the one simulated (but used different on/off switch due to the size of the breadboard).

2. Cut the needed Cardboard parts to build the enclosure.

3. Integrated the LEDs, switch and the fan into the cardboard, Removing them from the breadboard and connecting them to it using extra jumper wires.

4. made sure the 5V adaptor connection is fixed well.

5. Sealed the enclosure using glue.

Cutting the components' openings in the cardboard part as neat as possible since I used a thick cardboard this time.

Also in order to make it as neat as possible, faces were cut Separatly so when it came to assembly I had to use tape.

Troubleshooting was the first step actually to be done but no wires were faulty, all wires worked perfectly but crocodile wires occupied large space, if any other component is to be added then the enclosure must be changed.

Solution for these things is just to consider extra size and dimensions for a fully-intact Cardboard that can be folded into a closed box.
