Adventures in Circuitry!

 

How this quest started…

Every Valentine’s Day I like to make a special valentine with my son’s portrait. It usually involves some sort of crafting. This year (2018), I resolved to do something entirely different!

It wasn’t long before I was CIRCUIT OBSESSED and was, constantly, looking for things to ELECTRIFY! I advanced from one LED to many, from series to parallel circuits, from copper tape to solid wire, from one battery to multiple batteries with switches, buttons and dials, sound, lights and motion. 

Halloween got the circuit treatment…

As did Dia de los Muertos…

 

Even the Coney Island “Put On A Funny Face Mask Contest”…

Soon I was hacking everything in sight.

An Indian Buddhist shrine I’d rescued from the trash years earlier…

Two Exploratorium and one Chibitronics course later…

Interactive Illuminated Mandala

Can’t resist resistors if you want an illuminated RAINBOW mandala! No other way around that circuit! When using a combination of LEDs with varying frequencies, resistors help regulate the flow of electricity so that it gets distributed accordingly/efficiently.

Resistor resources:

To calculate resistor value/Ohms, given voltage supply & voltage drop. Click screenshot below. My parameters: 6 volt power supply, varying voltage drop values depending upon color and necessitating a dedicated resistor per LED and the ability to illuminate 8-9 5mm LEDs. A series circuit would have required considerably more voltage, but a parallel circuit required soldering a dedicated resistor to EACH LED.

CIRCUIT SAMPLER – for an Exploratorium Course

LIGHTS! MOTION! SOUND!

CIRCUIT SAMPLER 1

AMNH course –

Genetics, Genomics, Genethics

As part of the final project, I devised an Alien Genetics Assessment that included options for  illuminated alien DNA traits.
