Optical signal receiving circuit

Published:2011/4/29 23:31:00 Author:Nicole | Keyword: optical signal receiving

This circuit adopts a IR-B2M type photoelectric cell to receive optical signal. The optical signal can be visible light or infrared light, when it uses LED or semiconductor laser as light source, the best modulation frequency is 0.5~2.0kHz. When the light shines on photoelectric cell, the produced AC voltage is amplified by Q1, Q2, you can clearly hear the sound with a earphone, after a transformer which is fitting with the earphone resistance.   (View)

New timer switch circuit diagram

Published:2011/5/3 2:06:00 Author:Ecco | Keyword: New , timer , switch

The new timer switch circuit has the variable time adjusting function, it also has a countdown show feature, which shows the remaining regular time of the circuit at any time, therefore it is especially useful. The entire circuit is simple, easy to make, easy to use, suitable for installation in a variety of occasions. IC1 model is NE556 (NE555 can also use the two chips to instead). IC2 model is CD40110. The digital tube should use common cathode and high brightness LED. C1 uses the oil capacitor with the voltage in 400V, the capacity in 1μF . K1 uses the JRX-13F relay with pull-in voltage in 12V (to improve contact capacity, you can use two sets of normally open contacts in parallel). RP1 uses 0.5W ~ 1W shank potentiometer. S1 uses pole button switch. The remaining components are shown as the chart.   (View)
