- Finalizing outlook.

Outcome | Final Journal Video:

Progress : 

- Touch up calculation for finalization of internal mechanics.

- Added components for support in internal mechanics.

- Improvisation and adapting to new trial and errors.

- Tidying up internal notch and latches.

- Cleaning up outer look.

- Securing overall locks and internal mechanics.

Beta test 

FEEDBACKS

- Instruction word too small 

- Can't find the return ball place

- Instruction might need indication of number

CNC cut the shell of the capsule machine

- the outcome of plywood from CNC doesn't met our expectation

we use wood filling to fill those faulty holes.

-attach every layer together and follow the mechanics of our alpha test

15 Nov 2018

START TO BUILD !

• Fixing bug and ready files for cnc cut

• We calculate the wrong size again 

22 Nov 2018

Working on the base layer

1 Nov 2018

Prototyping

• Using cardboard to build out the prototype

Error & mistake faced

• wrong calculation 

Prototyping for the buttons and Servos

1. Research on the code 
2. bug fixing

Protoyping- .2

capsule machine mechanics try out

ERROR

• broke wires
• need to find out a way to stable the servo
• calculation problem

• sodering wire

PROTOTYPE OUTCOME 

For feedback

• too many steps for user
• change a way to release the ball.
• instead of word instruction, use icon would be better

CHANGES  ON THE MACHINE

We decide to change the ball release door from 

"User take out the ball from the compartment" to 

"The ball release itself when user press the start button"

Proceed with the design

- capsule machine use a "present box" concept for the design outcome

-Getting Message from others its like a surprise

FLOWCHART

1. User have to read thru the instruction shown in-front of the machine to understand how to use it.
2. After they read the instruction they are require to press the button at the  end of the instruction
3. Upon user press the button, a compartment at right-side below  of the box will open by a servo, and there is an empty ball inside for user to take it out.  There will be a green light LED shines on the ball, until user take the ball out the LED will become red.   
4. User will take the ball write and message to place in the ball. Then user need to toss it into the machine 
5.  Once the ball has being toss into the machine, a servo will unlock the latch for user to spin the notch.
6. In return user get a ball that has written message by other people.
7. As instruction stated user need to return the empty ball back to the compartment.
8. Once the compartment micro-switch detect the ball has being placed back the LED will return green again.
9. And the servo will lock the compartment door.

• usually the mechanics of  a toy capsule machine is operated by coin
• only a round object can push up the "obstacle" that blocks the notch

Solution

1. This capsule machine is no longer control by coins
2. if the sensor sense someone toss a ball into the machine, another motor will put the "obstacle" latch to let user to spin the notch

Below is the full mechanics concept of this capsule machine

The concept mechanics of the capsule machine

1. Once the sensor sense user toss in a ball, it will open up the latch and let the ball fall in

2.at the same time the notch will be unlock by showing green led

3.the ball holder will lead the capsule ball to the exit point of the machine
