persistence of vision toys

Scientific toys based upon the principle were developed in the early 1800s, but public fascination did not begin until the Victorian era. The illusion of films is based on the optical phenomena known as persistence of vision and the phi phenomenon.The first of these causes the brain to retain images cast upon the retina of the eye for a fraction of a second beyond their . If you have a row of LEDs moving very quickly, their light will hit different parts of your retina as they move. When the strings are twirled quickly between the fingers the two pictures appear to blend into one due to the persistence of vision. Each LED is connected to a data pin of the ATMega in series with a 100 ohm resistor making sure that the micro-controller pins were sinking instead of sourcing the current (most micros can sink more than they source).

Found inside Page 73As Jonathan Crary argues, widespread understanding of the persistence of vision, the phenomenon on which many optical toys relied, resulted in the introduction of temporality as an inescapable component of observation. I mounted a battery clip onto the back using some super glue and a single nylon screw (I only had one): As you can see, there is a keyring attached with dental floss to one side (I said it had to be stuff in my apartment!). is fairly difficult to read. Because the voltage drop across red LEDs is typically about 2v, this gives you a 1v drop across your 100 ohm resistor or about 10mA of current. Found inside Page 110Persistence of Vision Movies came to be through the discovery that if you moved a progression of images past the eye and the Zoetrope were fun optical toys that capitalized on this phenomenon, which is called persistence of vision.

Examples of common thaumatrope pictures include a bare tree on one side of the disk, and its leaves on the other, or a . Most used simple mechanical methods, such as spinning disks or turning spindles, to quickly transpose a series of pictures and so create the illusion of motion. 1. I fixed them on the schematic, but didn't bother on the PCB (notice the airwires). Found inside Page 104This play permitted children to test and refine their visual acuity in a controlled setting and to comment on and respond to optical displays around others.

When I was at the rock gym last week, one of the staff members had some gloves with blinking LEDs in the finger tips and was dancing around like an idiot. Dr. Peter Mark Roget learned of the persistence of vision effect and conducted experiments to investigate after images. This lets you "paint" images or text in the air. * A page on the Grand Illusions site discusses the point that "persistence of vision" is a misconception.
