It’s the 13th of February and your prospects are not looking good. You alternate between hating the holiday and signing up for a new free online dating service between bouts of sobbing. Let the tears fall down and wash away the pain, but don’t wallow in them.

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!

Step 1: Tools + materials

tools:
  • soldering iron
  • fabric iron
  • scissors
  • ironing board
  • sewing
  • machine/needle+thread
  • multimeter
  •  




 
materials:
  • 1 x BC547 transistor
  • 1 x LED (optional)
  • 1 x 5V relay
  • 1 x 7805 voltage regulator
  • 1 x 50k-100k potentiometer
  • 1 x 47ohm resistor 
  • 1 x 9v battery (and holder)
  • 1 x recordable greeting card
  • pillow fabric
  • scrap fabric
  • pillow batting
  • fine wire mesh / conductive fabric
  • fusible bonding matrix for fabric (Wonder Under/Stitch Witchery)
Remove the electronics from the greeting cards, but keep the stiff card back they are glued onto.

Step 2: Moisture sensor curcuit

This pillow works by sensing moisture and sending a signal to the electronic greeting card. I started this card working from this simple moisture circuit, but then went for an alternative route as designed by Jayefuu (credit for his schematic).

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.

It would be nice to have somebody care even if was jus a recorded song

I should rig up something like this to startle my daughter when she spills too much water on the floor when she's doing the dishes or taking a bath. Then she'll get upset, run to her room, and cry into her new sleepy weepy pillow . . .

Very good, but.......how bout modding this with a small low powered Taser, rather than gently cheering people up with song, it would smash them in the face with electric shock treatment.......the audio circuit could then say "dry your eye's fool and man up!"

My project design is the pillow you make for yourself, your project design is what you would make for your (soon-to-be) ex.

I like it!

can you turn it off? people who drool in there sleep wouldn't be very happy if it doesn't.

Nope.

Night-droolers and blubbery babies will keep tripping the circuit until the slobbery secretions, or the teary-eyed infants have stopped. Better suck it up, buttercup!
So evil...

I think J Timbs deserves a collaboration credit here.

I didn't want to drop specific names for wording...
But, if the JT side of the pillow get's a video then it only seems fair to share the flip side:
LOL... That's exactly what I was thinking when I saw the pillow...

JT could've sent it to Britney. ;)
