I`m originally a microbiologist specialising in respiratory viruses (but strayed into other viruses). I`ve reignited my physics A`level interest in electronics 1stly to mend a few devices and now to develop ideas I`ve had lurking in the back of my mind for years. Especially interested in audio circuits (despite some of my simplistic questions) I get irritated by patronising replies or pointless comments to peoples questions on here. You never know why someone is asking that question or what their background is (or what maarvel answering their question might give to the world in the end - don`t chase people away with silly or snide comments). ©
