This project implements the control of 2 lighting sets using a PIC18F252 microcontroller. The advantage of the digital controller is its increased flexibility. The brightness of the light sets are controlled using phase angle firing method, but with the intention of investigating the implementing of a burst firing method.
PCBs have always been my own personal Holy Grail, I’ve always wanted to make them on my own. Most online sources gave methods that involved using photoresist coating and UV exposure to make the patterns on the board. I’ve looked high and low for photoresist, and havent found it to date. Besides, if dust settles on the photoresist before it dries, it causes holes in the final PCB. Added to this is the "cooking period" under a UV lamp… basically way too much trouble for me. I was content with methods such as "Pseudo-PCBs" until I found out a way to make excellent quality PCBs without photoresist.
This is a description of how I currently implement circuits. These may not be the best ways to build circuits given the circumstances, but it works for me. Other methods (not covered here) include the dead-bug style, Manhattan style, etc. For more info on these, search for "dead bug style" using Google. PCB etching too, has several methods, many of which are either out of reach or impractical for the average experimenter.
