Tell us about yourself!
Interesting. Although it is hard for me to read this (taken from lcd.h): ---本程序只供学习使用，未经作者许可，不得用于其它任何用途This procedure is for study only and may not be used for any other purpose without the permission of the author---Well that is precisely what I'll be using the code for: study it. Maybe I will make something similar to this too. Thanks for sharing!
Yes, that metallic tape probably is a good idea. I went for an aluminium plate with wooden strips around it and a thin wooden plate on top. In the plate on top I have installed two slow rotating fans (less sound) and the heat is duckted away. But then again I use far more power (approx 100W) and the whole setup is only slightly larger than yours is. Without the fans the temp would quickly rise above 60 Celsius (then I start burning my hands)
See my reply to ThinkTinker, I use far more power. BTW, I have mixed red, blue and white leds.
