555 musical flashing electronical ball circuit used in the game of passing hydrangea macrophylla

Published:2011/7/18 5:18:00 Author:nelly | Keyword: flashing electronical ball, game, hydrangea macrophylla

IC1 adopts the time base circuit 555, the monostable delay circuit is composed of IC1, R1, R2, RP1, C1. Before playing the game, the switch SN should be cut off, 555's 2 foot is high level( it is connected to VDD by R1), 555 is in reset state. When playing the hydrangea macrophylla, you must press SN first then pass the hydrangea macrophylla, due to 2 foot's low level, 555 is set, the high level which is outputed by 3 foot provides IC2 with working voltage. When you arepressing SN, C1 discharges inside the chip by 555's 7 foot; after it, SN cuts off, the chip internal discharge lamp turns off, C1 is charged by R2, RP1, when C1's voltage is charged to 2/3 VDD, namely, 6 foot level reaches resetting voltage, 555 turns to reset state, 3 foot turns to low level, IC2 is no electricity and it stops phonating.   (View)

DC / DC converter circuit diagram composed of NE555

Published:2011/7/24 21:57:00 Author:Ecco | Keyword: DC / DC converter

This is a converter circuit without transformer. In the circuit, power transistors VT1 ~ VT4 form the bridge circuit with alternating switch working mode, and when VT1 and VT4 are turned on, VT2 and VT3 are turned off, and it has the opposite turn in the next cycle, that is, VT2 and VT3 are turned on, and VT1 and VT4 are turned off. Bridge's A and B output AC voltage with rectangular wave, which is converted into DC voltage by the rectifier bridge VDB. NE555 is the oscillator circuit, and the oscillation frequency is decided by the R1, RP1 and C1.   (View)

Telephone disconnection detection circuit diagram

Published:2011/7/24 21:45:00 Author:Ecco | Keyword: Telephone disconnection detection, MOSFET

The chart shows the telephone disconnection detection circuit, which is based on the offset micro power consumption oscillator provided by telephone lines, and it generates differential signals, which is added to the circuit by the high voltage capacitor. These capacitors can provide the necessary isolation, and only when the output load of the oscillator itself is negligible, the detection circuit can detect oscillation. Oscillator uses the astable multivibrator composed of VT1 and VT2. This oscillator depends on the transistor collector resistance.   (View)
