Delayed light out circuit of motorcycle brake light

Published:2011/3/31 2:26:00 Author:Nicole | Keyword: delayed light out, motorcycle brake light

The circuit principle as shown: S1 is power switch, controlled by frame lock, S2 is brake light control switch. closing switch S1, because the voltage in both ends of capacitor can be sudden changed, IC's ② pin is low level, brake light H on, a few seconds later, C1 is discharged, then the IC's ② pin voltage is higher than 1.6V, light H off. When the driving motorcycle is slow down or stop in an emergency, switch S2 is closed and shortened circuit both ends of C1 then discharge, turn switch IC's ② pin into low level, brake light H is lighted immediately, S2 resets, H is extinguished after a few seconds later. IC in the circuit is high power switch integrated circuit TWH8752, the maximum current is 4A, H is rear brake light, R1 is 470K, C1 uses 16V, 47μF electrolytic capacitor, C2 uses 25V, 2200μF electrolytic capacitor, VD1 uses 1N5408 rectifier diode. If it needs to change the delay time, just to change the values of R1, C1 appropriately.   (View)

General-purpose function generator

Published:2011/4/17 20:52:00 Author:Ecco | Keyword: general-purpose , function generator

Signal generator can be divided into three parts: the sine wave and triangle wave generator, counter and pulse and ramp generator. The circuit is as shown, XR2206 adopts voltage controlled oscillator, the frequency adjustment is achieved by potentiometer RP5 (10k), it is easy to adjust to the frequency in one-thousandth. If you change the resistance of the fixed resistor R3, the resistance of the RP5 could also be changed. Sine and triangular waves is different from other similar instruments, the attenuator switch Sl only can change the magnitude of signal, it does not affect the bias voltage. According to the need, the fixed attenuation can be got (to 20dB, the voltage ratio is 10), it adjusted by R6, fixed resistor R7 connecting in parallel. It also could connect to rheostat to adjust resistance. Although the adjustment of resistance is more expensive, but it is easy to implement.   (View)

NE555 alarm circuit diagram

Published:2011/4/17 20:36:00 Author:Ecco | Keyword: alarm circuit

The alarm is composed of two parts of the transmitting and receiving. Transmitting circuit is shown in Figure 1. It consists of two vibration temperature circuits with different frequencies and they are composed of two 555 time-base circuits. When the two ends of CK are in short circuit, the first(IC1) 555 constitutes a low-frequency shock temperature circuit, the frequency F1 is mainly decided by C1, R2, the output frequency of pin 3 is the low-frequency signal of F1. When the output of pin 3 is in high level, the second (IC2) 555 constitutes a high-frequency shock temperature circuit, the frequency F2 is mainly decided by C3, R4, and F2 much higher than F1, so the output of pin 3 is the pulse modulated signal of F2. The modulation signal throughs the driving circuit composing of Q1, T1, C5, C6 and produces high frequency modulation pulse on the power line, the voltage of high frequency modulation pulse is decided by transmission distance.   (View)

74 series digital circuit of 7497 synchronous 6 binary coefficient multiplier

Published:2011/4/2 3:58:00 Author:Ecco | Keyword: digital circuit , synchronous 6 , binary coefficient, multiplier

Executive fixed coefficient or variable coefficient fractional frequency: typical highest clock frequency 32MHz; When clearing, choose input for low level, counter begins the work, the output frequency equals to input frequency multiplied by input coefficient divided by 64. H is high level, L is low level, X is uncertain, others are digital reading. 1. This is a simple chart to show the clearing function. The state of clock and strobe will make an influence on the logic level of Y and Z. For example, the unit /cascade is in low level, the output will keep high level. 2. The coefficient in input terminal is constant or variable coefficient input. 3. The unit/cascade is not allow to output Y.   (View)
