I am primarily Husband, Father, Grandfather. As a technologist, I have spent most of my working life working in IT. Now that I am retired my main interest is in the environment, gardening, ecology, air quality. See theoldgarden.ie, my passion, we are developing a community garden. I have an X1 Carbon and an older Qidi xPro. I use FreeCad for design and learn something new every time I sit down to do some serious design work. I qualified in Computer Science in Trinity College Dublin. I use Arduino's, Raspberry Pi's, mostly Python programming and a little C++ . Also see Climateresponse.ie.
