If you have space at home...you can put it in your glass cabinet or something like that as a decoration...That's what I intend to do with my old polaroid camera...but I don't have space for a glass cabinet to display some decorations yet haha..
Then as time past as you change your equipment...your items can form some kind of "historical" decorations of technology over time.
P.S: I meant if your old stuff is camera or lens....if it is some accessories then you have to think of other alternatives.
Thanks for feedback.
I am making plan for my old D40.
I saw some ppl convert old camera to IR. My friends all have better. Want to check with CS friends how many ppl does the IR convert or got more option be giving to S Army.
