I don't know whether the powers that be on this forum will allow me to blast my own trumpet loud and clear but my latest book has just been published. It contains some chapters on weather/climate-related subjects but it has not forecast the icy blast from the East in northern Europe. However, it has little content on printed circuitry other than where our industry may be polluting. It can be found at https://www.amazon.co.uk/Green-Heart-Perhaps-Singing-Date/dp/1786938243/ or https://www.amazon.com/Green-Heart-Perhaps-Singing-Date/dp/1786938251/ or https://www.amazon.de/Green-Heart-Perhaps-Singing-Date/dp/1786938251/
