MAKE Asks: is a weekly column where we ask you, our readers, for responses to maker-related questions. We hope the column sparks interesting conversation and is a way for us to get to know more about each other.

This week’s question: Many of us are parts hoarders, and mostly with good reason: one never knows when something in the stash can come in handy. But what are parts or materials that you simply have an overabundance of? For other readers, what sort of projects would you use those parts for? Maybe in the comments thread we can get some match-making action going.

I have ten 4N32 Opto-Couplers that I don’t see myself using anytime soon. I’d gladly trade or give them away if you can find a use for them. Hit me up in the comments if you’re interested.
