Decided to build a container for my arduino. Emptied out a nice curious box that I use for holding tie tacks and stuff. Marked drill holes by placing the board in and using a ball point. Fired up the drill and then remembered I have no idea what size of hole I need for the stand-offs. Two firsts: I have never needed stand-offs before. I have never lacked for them. Oh sure, I could rip apart my computer. Or I could rip apart my Sun. Or I could find more elsewhere. Option 3.
