教如何用旧寻呼机改升压电路

<P>旧寻呼机很多人都留有在家里,现在我跟没有学过电子的和不方便买到升压电路的人如何</P>
<P>将废物改成LED驱动,可以用一个AA,也可以用两个可充AA或AAA电的电筒。</P>
<P>但先要在电子店买到低压起动的超白LED灯,因为寻呼机出来的电压只有3.02V.,</P>
<P></P>
<P>这是一个坏的数字寻呼机。我们要的只是红笔圈子里的四个小东西。</P>
<P>把别的所有零件拆下来只要其中四个把板子剪到最小。</P>
<P>+号为正极,绿色为负极,</P>
<P>电解电容可以用机上大一点的贴片电容代替这样体积可以变小一点, </P>
<P>.,也有一些寻呼机是这样的电感</P>
<P>和二极管有点不同,
</P>
<P>要最小的部分,
剪下成这样子</P>
<P>最后就。。。。

哪里有卖呢?

<P>好,回去后拆机再看一下,虽说是好的,可已经很久没用那东西了</P>

找点6101 6102 6103 效果很好的价格也底</DIV>

我刚用过,6103驱动3只有点勉强,只有3.1V,厂家说了,我买的8050是假货,我可是从进口电器上拆的。让我试场效应管,没时间。

6102和6101是什么IC.一般的电子店有售吗?样子如何的,有人帮忙放出来给看看吗?买回后用什么电路呢?谁可以教一下我.谢谢

我也想知道。

楼主辛苦了!

我觉得拆你要的那几个零件自己焊还方便些,不用电路板,搭线焊接就可以,可能比你的那个体积还要小

楼上的,受电感功率的影响不能扩容,功率大后电压会下降,电源内阻较大

用大电流的本坛有专门制作文章参考,呼机电路有很多元件,http://bbs.leowood.net/web/leowood/forum/incomefiles/20058181884057987.JPG黄色电容两端就是3v,电路图没有

但先要在电子店买到低压起动的超白LED灯,因为寻呼机出来的电压只有3.02V.那不是太浪费了啊,直接买个升压电路得了,这个DIY的代价有点高.
