Physical Computing - Week 2: Application for Switches and Circuits
TITLE: Vending Flashlight
DATE: September 2016
INSTRUCTORS: Tom Igoe
TOOLKITS: Analog Circuits
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.
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.
