You could write a letter or poem about how your lover makes your heart beat (faster), but this leaves a lot to the imagination. As a true engineer you obviously demonstrate this with a top piece of electronics. If it concerns a declaration of love you can immediately overwhelm him or her with your (soldering) skills. The heart is supplied as a kit with separate circuit board and parts to practice soldering. This kit is not only fun to watch, but also very instructive to make.
