那種電路適合我呀???
2007-08-25 9:52 pm
我是一個電子初學者,我對一些電器電路很感興趣,經常看一些電子和物理書(都有一年),所以對基礎電子零件都有一定認識(但不是很專業),,,現在我好想親手做一塊電路板出來....希望大家介紹一些適合我程度的電路給我實習下(最好簡單d),,,,,,謝謝

✔ 最佳答案
你有無足夠工具? 你所指做一塊電路板, 是指???電路板分:1. 印刷電路底板, 需要很多設備. 2. 萬用底板, 需要用電烙鐵焊接線. 3. 麵包板, 只需插線.
簡單D, 可以到電子零件行選購一些套件, 已包零件, 印刷電路底板, 只需有電烙鐵便可, 複雜和簡單都有, 價錢由廿零蚊至幾百蚊都有.
可到以下網址找找你喜歡的電路:

你若想用套件, 到羈寮街華輝有很多音樂門鐘選擇, 那裏亦有很多電路製作的書.

very simple
穩壓電路
it is simple circuit, all u need is a transformer (220v to around 10v-15v), 2 e-Cap (~1000uF, 25v), 2 ceramic cap (0.01uF, 25v) and a power regulator IC (78xx, xx is the voltage, say if u need 5v you need 7805), this can also be used as one of the tool in your future study
計時電路
a NE555 IC and a few cap and resistor, can be used to control simple on/off application if you add some driver circuit of small relay
震盪電路
2 transistors, few cap and resistor can generate audio frequency.
you can find the above circuit in the internet...

you have the answer already before posting the question, do you?
