Modding RGB cooler

   Now pass to making the electronic part of the mode, namely to the special effects controller that will control the light diodes.
   Single-chip processor ATMEGA8 is the heart of our special effects controller. A peculiar program was written for the processor and was programmed into its permanent memory with the help of programmer. The following manual will teach you how to program such processors without assistance, how to assemble the programmer and the controller itself.
This article is intended for prepared reader, that’s why I won’t describe in details the principle of operation of the circuit itself. The circuit is simple and contains very few details what makes this modding available even for the beginners…
  Thus, lay out the printed circuit board of the controller according to the pattern. Draw lanes and etch it in ferrichloride. (The circuit board layout is given for DIP case, ATMEGA8 can be planar, so you’ll have to redraw the board in the event of TQFP or MLF cases).
 
 

Tin:

Solder the elements. Solder a panel for 28 needles in case of single-chip.
