Power a breadboard with a wall wart.
2.1mm Power Jack (TaydaElectronics.com, Part# A-4118) Double row pin header (Tayda, Part# A-198) 2 position screw terminal (Mouser.com, Part# 538-39880-0302). The screw terminal can also be had cheaper at Tayda, but I wanted it in black to match the 2.1mm jack.
Those 9 volt snaps always seem to have stranded wire leads, making them hard to plug into a breadboard. Tinning the leads can make them too thick to fit.. With this you can just plug the 9 volt snap leads into the screw terminal and call it a day. Or just plug a wall wart into the 2.1mm jack instead.
NOTE: Although you see holes, the 2.1mm jack holes are actually slots, so they work with normal “solder lug” style jack slots when fabricated (notice the rectangular outlines there). You do NOT need a jack with PCB pins.
