Very old. Started in electronics with thermionic valves! Progressed into computing with machine code programming, then minicomputers and finally PCs and web based systems. Have kept pretty well up to date since retiring with Arduino projects (one commercially viable).
Am a maker, originally traditional woodworking/cabinet making. and model making. Increasingly using automation to compensate for arthritic hands.
Have GRBL CNC machine, 3D printer and an assortment of hobby lasers.
