this week's assignment mini smart device made with cardboard, has two different outputs, so let me think about what can do.
I love American coffee and latte, I found it on Amazon, and it was costly.
so, it inspired me to make a coffee mixer for making excellent foam in coffee
For soft ware: use tinker cad to design the circuit and simulate it to try it first.
For modeling: use cardboard, glue gun , scissors
For Hardware: use adaptor 9 volts as a power source, jumpers, mini breadboard to collect jumpers, crocodile jumpers , switch to pen and close the circuit, bulb for lighting, Dc motor
simulating circuit
First, open Tinker cad and create a circuit, then choose the component of the circuit that I mentioned above.
I connected the output component in a parallel circuit.
Put the negative and positive from the 9v adaptor to the breadboard, connect the positive (1) side switch with the positive side, and ground the (0) side of the switch in a different place in the board. The positive side of the switch makes current go through the circuit, and the negative(ground) side opens the circuit and prevents the current from flowing.
Connect the LED the negative with the negative side and the positive with the ground(0) side of the switch.
Connect the DC motor to the negative with the negative side and the positive with the ground (0) side of the switch.
Try simulation to make sure that the circuit is right.
First, for the cardboard: I cut the cardboard as the body of the device a rectangle 15*17 cm to make a cylinder shape, and made a hole for the led, The top circle part made a place for the switch and power. and for the motor a smaller cylinder with a radius of 3.5 cm and 3.5 height and closed with 3 com radius circle .
Then, for the circuit: set the pins of the power source on the breadboard the red jumper as positive and the brown as negative, then connect the switch with jumpers and set the pen of a green jumper as positive and the yellow one in another line.
for dc motor, connect the crocodile jumpers with the motor and the other side with male\male jumpers, put a motor on its cardboard part and set the pin of a black jumper with negative and the red pin with the positive yellow jumper of the switch.
For the bulb, connect with male jumper with green as negative and yellow as positive, set the pin of green on bread board with the negative side and yellow on the positive side with yellow one of the switch.
collect the wires with tape
Finally, test the circuit, then put all components together on cardboard and rearrange them to show the final project, I tried to make the mixer with copper wire and connected it with the dc motor with tape.
Finish the cardboard with the glue gun and put your magic touch on it.
first, I used a 5v adaptor as a power source, I found the dc motor was slow, and when I added the copper mixer with the motor it stopped, so I replaced it with a 9v adaptor and it was much better.
It was very interesting to create a device that I actually use and make myself.
in this EOW we made a mekathon and it was very funny .
my team choose to design the body like a scorpion and we named it Azza (عايزين عزة 😂)
the vibes were hard and very competitive but we had fun and enjoyed it 💕
