Physical Computing - Week 2: Application for Switches and Circuits

TITLE:  Vending Flashlight

INSTRUCTORS:  Tom Igoe

COLLABORATORS:  N/A

TOOLKITS:   Analog Circuits

 

INSPIRATION

This is an application for switches and circuits. In the course Pcomp, we were asked to create a stuff using self-made switches and LED circuits. I was inspired by a song named Old 45s, it sings:

If you think romance is dead and gone,
Find an old jukebox full of 45’s,
Pop a nickel in it and it all comes back to me

So I decided to do some changes with my flashlight project before, and turned it into a “JukeLight”, which you pop a coin in it and it will create light.

 

RAW MATERIALS AND TOOLS

The Circuit and The Switch. Actually, I used a 3V mini E10 light bulb instead of a LED, but the circuit was the same as the LED’s.

 

THE PROCESS

FINAL WORK

 

THE TAKEAWAYS

A tool named iCircuits, which is useful to draw a circuit on Mac! Tom also suggests Cirtuits.io and Fritzing to draw circuit diagram.

Read the pack instructions and labels of the accessories, it helps a lot!

Different kinds of metals have different amount of resistor, sometimes you could remove the resistor of your circuit for the total amount of resistors.
