Let the Sleepy Weepy Pillow lift your spirits and rock you gently to sleep. With its moisture sensor, it knows when you’ve been weeping. It does more than acknowledge your sadness, though, it will even buoy your spirits with the song or inspirational message of your choice. Using a recordable greeting card you can include your own soothing message or music, sure to make you feel a little better.
So buck up, buttercup. Choke down that last sob and warm up your soldering iron, it’s time to take matters into your own hands to make yourself feel better. It's time to make a pillow that knows when you're sad!

After wiring all the components into a stripboard, leads were attached from the terminals of the greeting card to the relay and the stripboard circuit was attached to the back of the electronic greeting card.
