笔者有一台随身听单放机,它给我带来很大的欢乐。可最近却使我感到苦脑。因电池用了一大堆,花去很多钱,虽然也有可充电电池,不是忘了充电,就是充电太耽误时间,怕麻烦。想买一只市售整流器价格很贵,无奈之下我就想到利用身边闲散配件自制一个整流电源。于是,自己动手在未花多少钱的情况下制作了一只输出电压在3 V、电流在350 mA的整流器。有兴趣者不妨自己动手自制。
I have a Walkman player, it brought me great joy. But recently I felt bitter. Due to a lot of battery used, spent a lot of money, although there are rechargeable batteries, not forget to charge, that is, too much time to charge, for fear of trouble. Want to buy a commercially available rectifier price is very expensive, desperation I thought of using self-made spare parts around a rectifier power supply. So, do it yourself did not spend a lot of money to create a case of the output voltage of 3 V, the current 350 mA rectifier. Interested parties may wish to do it yourself.
