Question: what is the best thing you made

I would say the best thing I have made would be the instrument which scans underground, it has the possibility to save lives from detecting things like mineshafts which houses and buildings could collapse into, as well as things like buried explosives in warzones

It is a rewarding feeling, making something like that, plus I got to mess around with all kinds of crazy electronics, including fibre optics and amplifiers putting out thousands of volts of electricity!
