Door Alarm! 请各大大进来看-有电路和inductor照片了(有声有灯但没触摸驱动效果)
我要做个小的电子project.
比如,SOUND DECTECTOR SUIS,
LIGHT SENSOR CAMERA只要有光它就会直接拍相。。。等等。
请各位大大可以给我,idea和提供我电路吗?

对不起,大大...
我想问...能在网上察到那些零件在PASAR ROAD买得到吗?
因为我在网上找了些project design circuit diagram,但我又不确定在这里会买到吗.... |

Device purpose:
This circuit emits a beep and/or illuminates a LED when someone touches the door-handle from outside. The alarm will sound until the circuit will be switched-off.
The entire circuit is enclosed in a small plastic or wooden box and should be hanged-up to the door-handle by means of a thick wire hook protruding from the top of the case.
A wide-range sensitivity control allows the use of the Door Alarm over a wide variety of door types, handles and locks. The device had proven reliable even when part of the lock comes in contact with the wall (bricks, stones, reinforced concrete), but doesn't work with all-metal doors.
The LED is very helpful at setup.
Circuit operation:
Q1 forms a free-running oscillator: its output bursts drive Q2 into saturation, so Q3 and the LED are off. When part of a human body comes in contact with a metal handle electrically connected to the wire hook, the body capacitance damps Q1 oscillations, Q2 biasing falls off and the transistor becomes non conducting. Therefore, current can flow into Q3 base and D3 illuminates.
2.他是怎么运做的??HOOK没connect双头...人体触摸可以驱动???不明白
If SW1 is closed, a self-latching circuit formed by Q4 & Q5 is triggered and the beeper BZ1 is activated.
When the human body part leaves the handle, the LED switches-off but the beeper continues to sound, due to the self-latching behavior of Q4 & Q5. To stop the beeper action, the entire circuit must be switched-off opening SW2.
R3 is the sensitivity control, allowing to cope with a wide variety of door types, handles and locks.
Notes:
· L1 is formed winding 20 to 30 turns of 0.4mm. diameter enameled copper wire on R2 body and soldering the coil ends to the resistor leads. You should fill R2 body completely with coil winding: the final turn's number can vary slightly, depending on different 1 or 2W resistor types actual length (mean dimensions for these components are 13-18mm. length and 5-6mm. diameter).
3.这inductor 要自己做的????
· The hook is made from non-insulated wire 1 - 2mm. diameter (brass is well suited). Its length can vary from about 5 to 10cm. (not critical).
4.这是什么来的?也要自己做???
· If the device is moved frequently to different doors, Trimmer R3 can be substituted by a common linear potentiometer fitted with outer knob for easy setup.
5.Trimmer 是什么? R3不是resistor吗?
· To setup the device hang-up the hook to the door-handle (with the door closed), open SW1 and switch-on the circuit. Adjust R3 until the LED illuminates, then turn slowly backwards the screwdriver (or the knob) until the LED is completely off. At this point, touching the door-handle with your hand the LED should illuminate, going off when the hand is withdrawn. Finally, close SW1 and the beeper will sound when the door-handle will be touched again, but won't stop until SW2 is opened.
· In regular use, it is advisable to hang-up and power-on the device with SW1 open: when all is well settled, SW1 can be closed. This precautionary measure is necessary to avoid unwanted triggering of the beeper.

各位大大,请帮我...
我不是很明白这circuit 的运作.....
这个电路对初学者会有一定的难度。。
啊,你先前不是要做光控,声控的吗?
1.这是普通的speaker 吗???
2.他是怎么运做的??HOOK没connect双头...人体触摸可以驱动???不明白
3.这inductor 要自己做的????
4.这是什么来的?也要自己做???
5.Trimmer 是什么? R3不是resistor吗?
1。不是,是Piezo Buzzer
2。是人体电容令到振荡改变。
3。是。
4。是。钩在门把的裸铜线。
5。Trim-pot,可变电阻。

5。Trim-pot,可变电阻。
1. 懂了..这大概要多少钱??
2. 是人体电容令到振荡改变.
就是说人那HOOK只需挂在门巴那边,等人触摸了就会驱动?
3. 在PASAR ROAD可以买到0.4mm. diameter enameled copper吗?
4. 钩在门把的裸铜线这也可以买到吗?
5. trim-pot 也是potentialmeter?为什么我网上找trim-pot,它给和多RESISTOR和POTENTIALMETER的MODEL???
大大,以你的经验....所有这些东西是不是能在本地找到???
怎个CIRCUIT的完成大概需要多少钱?会超过RM100吗???
对不起!很多问题....
谢谢你帮.... |

少过RM1.00
2. 是人体电容令到振荡改变.

不是很具体,但也可以这么说吧。。。
3. 在PASAR ROAD可以买到0.4mm. diameter enameled copper吗?
随便找Single core wire 就可以了。
4. 钩在门把的裸铜线这也可以买到吗?
随便什么电线就可以了。
5. trim-pot 也是potentialmeter?为什么我网上找trim-pot,它给和多RESISTOR和POTENTIALMETER的MODEL???
trim-pot ,potentialmeter都可以用。
大大,以你的经验....所有这些东西是不是能在本地找到???
可以。

不会超过RM100。
但你要完成的时间就很难说。。。 |

对,但如果接错呢(运气不好)?又不知道那里错? 这时头就晕了。。。。 |

那是电阻的功率。你买时店员有问你就说要1/4watt的, 1/2watt的也可以用。
3.买回来后,要怎样CHECK到它是不1/4或多或少1/2W啊??
从体积就可以知道那是1/4, 1/2watt。
4.2΅2 25V Electrolytic Capacitor
100΅F 25V Electrolytic Capacitor
它的VALUE是多少啊????
5. PASAR ROAD没买价2.2F的....它是2.2micro F???
2.2uF 25V, 和100uF 25V。
6. 全部component后面那些注明的Volts买时也要跟着买吗??
16v也可以用。
7. L2_____________10mH miniature Inductor
这个我找不到啊... 要自己做?
可以买到, 它的样子是很像Resistor, 一般是青色。(Resistor是褐色,乳白色) |

这project对你来说会有难度,你可不可以做成,运气成分很高。
何不考虑作简单一点的?
你不是要做光控的吗? |
