Who says that spending hours locked away in a studio making music has to have a detrimental effect on your love life? Make your partner a musical bra - two birds, one stone.
The idea is simple: take the electronics from a cheap toy keyboard, take one brassiere (preferably of the stretchy, front-opening variety), a speaker and a soldering iron and follow this step-by-step Instructables guide.
The prototype features eight different sounds in each cup, triggered by in-built buttons (strips of conductive fabric separated with strips of foam). The speaker is out up-front while the batteries sit behind between the shoulder blades.
Make it, wear it, caress it, make sweet, sweet music…
