The exposure time control circuit diagram

Published:2011/3/30 21:49:00 Author:Ecco | Keyword: Time exposure

To assure the quality of the photogragh, this device can satisfy the shutterbug to control the time of exposure. It has the advantages of high accuracy in time controlling, having universal function such as time exposure, light-dimmer, pressure regulating and so on. Enlarging bulb or iron, electric blanket and lamp. The electric applianceses, such as electric fan and dynamo. etc. can be connected to the output socket CZ, and the output is controlled by the silicon capacity. For example, the pure resistive load can provide the power with 600 W; capacitive or inductive burden make the output be smaller than 300w.   (View)

Sensitive Oscillator Circuit Diagram

Published:2011/3/30 21:42:00 Author:Ecco | Keyword: Sensitive Oscillator

As shown as below, this oscillator is a type without steady-state harmony which composed of 555, R1, R3, C1 and optics triode VT. The internal resistance is changed with the illumination, and when the light is strong, it presents in low resistivity, when the light is weak, t presents in high resistivity. So the frequency of oscillator changes with the light in the range of 1Hz～6.5kHz. So the oscillator is available to make blind man to explore the way, early dawn report Xiao etc. situation.   (View)
