you're welcome!  Post #9  
let me try,my eng is poor,so that i hope you could understand what i say.

the original diyer's projet:

1.modify the power supply :add a power plug receptacle(easy to change the power line),change the old power transformer to a 50W 17V~X2 EI transformer(look at the pic below).


+5v to crystal, digital output board
+5v to mainboard
+5v to display ,control panel
+12v to motor drive

2.change the original electrolyte caps to philips caps or nichicon caps,and the terylene caps to polypropylene caps.

3.change the 3pin crystal to a high quality 4pin crystal. and take out the 1M resistor and the 33pf cap at the 71pin(xin) and 72pin(xout) of the saa7341.the high quqlity crystal's out pin solder to the 71pin of the saa7341.the 32pin of the 7341 is the digital output, solder it to the digital output board's(by buy) input pin.








the green board is the digital out board.

4.add a infrared remote control:


add 4 components: the sony's infrared receiver , 4.7k 100 resistor and a BC560

想玩玩

做的不错..

yanzhouzhu

请问&lt;我爱DIY&gt;这样一改电源开关不起作用了你是怎么解决的呢?

ahgh789

请问一下能把加装红外遥控的部分说得详细点吗？

bj1876

学习

呵呵

这样该开关一定是没用了.要另外加,四脚晶镇很好那里搞的能帮我搞一个吗?

呵呵

另外我想问 下这个机器光头线很难拆下,手进不去,我是连头带板拿下再拆头的,老兄是怎么拆的呢?
