I generally refer to myself as just a "maker" as wood isn't the only medium I use, though the majority of the woodworking I've done is "furniture" - a table, freestanding shelving, several desks now, two bespoke fire surrounds, several other things. To date I've made just one box!
AJS - I understand your reticence at using the term "maker", but I think from your self explanation that is indeed what you are, expecially if you are using plastic and electronics as I do.
I'm pretty certain most "inventors of things" - that we now use everyday would have been considered "irresponsible" by thier more staid peers, so it's not really fair to use that against other makers, do you not call yourself a driver merely because of the other idiots on the road? A great many of our everyday items came about in whole or in part because of "mistakes" or outright failures when attempting to get a different outcome.
