I have a reasonable knowledge of electronics and wiring
but my difficulty lies in the circuit
board designs, especially when IC`s are involved. Fortunately this site has some very good people willing to help. I have been helped a lot by Doug, (RNinMunich) who is always happy to advise.
Due to only requiring a small quantity of electronic items such as LED`s at a time, I buy most of them through ebay. I would recommend bright_components for LEDs and resistors. They sell most things needed for the boat build
er where electronics are concerned. 😊
