Digital Camera

A little history

An engineer by the name of Steve Sasson was the one to invent the first digital camera in December 1975. Steve Sasson was an engineer that worked at Eastman Kodak. He made a blog post to social media in the year 2007 talking about how he had came to making the digital camera.


"It had a lens that we took from a used parts bin from the Super 8 movie camera production line downstairs from our little lab on the second floor in Bldg 4. On the side of our portable contraption, we shoehorned in a portable digital cassette instrumentation recorder. Add to that 16 nickel cadmium batteries, a highly temperamental new type of CCD imaging area array, an a/d converter implementation stolen from a digital voltmeter application, several dozen digital and analog circuits all wired together on approximately half a dozen circuit boards, and you have our interpretation of what a portable all electronic still camera might look like." -Steve Sasson > Eastman Kodak

What Elements make a Digital Camera

-Cadmium

-Aluminum

-Nickel

-Lanthanum

Lanthanum

p+ =57

e- = 57

nᵒ =82

where does Cadmium, Aluminum,Nickel, and Lanthanum come from??

CADMIUM

The element Cadmium is produced in multiple countries. China, Japan, and Korea are the world's largest producers, followed by Mexico, the United States, the Netherlands, India, the United Kingdom, Peru and Germany.

ALUMINUM

The element Aluminum is naturally found in the form of bauxite (a rock that contains aluminum oxides an dioxides), an aluminum ore contains oxide, or alumina. We surface mine bauxite from places in Australia, Brazil, Suriname, Jamaica and other parts of the world.

NICKEL

The element Nickel is mined from multiple nickel ores such as= pentlandite and pyrrhotite (iron Nickel sulfides, the two most important nickel ores), garnierite (hydrous Nickel silicate), millerite (Nickel sulfide), and niccolite (Nickel arsenide).

LANTHANUM

The element Lanthanum is mostly obtained from lanthanum-rich monazite and bastnasite. Other lanthanum-bearing minerals include allanite and cerite. It is mined in the USA, China, Russia, Australia, and India

Recycling Digital Cameras

It is pretty easy to recycle used, broken, or unwanted cameras. Some brands sell prepaid UPS labels that allows you to take your cameras to a UPS store where they will properly dispose your camera. If you don't have the UPS labels then you can take it to you recycling center. If you do not know where your local recycling center is then just call town hall or library. They will feed the donated cameras through a conveyer belt dropping it to a large machine that shreds your cameras and then the pars will get put in groups, melted and mad into other digital cameras.

Lanthanum hydroxide= La(OH)3

This is an ionic compounds because ionic compounds are made up of metals and Lanthanum is metal
