Famous industrial designers talk about iconic pieces of technology.
We asked prominent designers featured in this issue to help us see, through their eyes, pieces of technology that have influenced the way they think about their work. View these pieces of technology on the following pages or in this photo essay.
1972, Polaroid SX-70
Polaroid's first fully automatic, motorized camera was an instant design classic, even starring in a documentary the year it was introduced by company cofounder Edwin Land. The camera is detailed with tan leather and folds into a rectangle the size of a paperback book. Andrew Logan, principal designer at Frog Design, admires it for the "immediacy of a favorable output." He explains: "Instead of waiting days to see if you took a good photo, you could take it again right away."
Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor.
Most measurement devices can measure voltage. Two common voltage measurements are direct current (DC) and alternating current (AC).
Learn the fundamentals of creating an AC or DC voltage measurement system. See how to properly connect the signals to your data acquisition system for accurate acquisition.
