The video for this week is here.
Lights and the birthday tune done on the Arduino.
The upload is attached here.
This simple toy is my subject to teardown. Powered by AAA batteries it involves a rotatory motion and lit LEDs when a button is pushed.
The initial unscrewing yields the inside of the toy.
Taking out the useful part from the casing shows a button, 5 LEDs,small circuitry,a motor and connecting wires.
Exploring each section separately, the lighting component of the toy is shown. Consisting of 5 LEDs connected in a simple circuit.The only use of the circuit board is powering the LEDs,which are soldered to the board with wires.
The Pushbutton type switch is used to operate the toy.These switches complete the flow of electricity when they are pressed. When a pushbutton switch is in the on position, a spring inside the electrical device makes contact with wires that will allow the current to flow. Then, when the switch is pushed down again, the spring inside retracts, and this stops electrical current, deactivating the device.
For the rotary motion, the toy uses a brushed DC motor.
The final layout is shown as,
The tools used in this operation are,
Head- Making a mould and casting
Body- Making a mould and casting
LED Lights- A semiconductor wafer,multiple wafers are joined to become a semiconductor,Ultrasonic process to clean it.
Electrical components- Include highly detailed intricate processes,although very cheap to make.
The one design choice I like is the simplicity of the button placement. Very child friendly and surprisingly sturdy.
