This is a pillow... with featuers. Who doesn't want a pillow with features? What we've got here is an exciter on a plate of polypropylene stuffed inside a pillow. Its an emerging technology- I've never actually seen it done diy before. That being said, inspiration comes from a real product- the Dream Pad, which went on SharkTank. This one also has a little scent pocket sewn in.

The Idea In theory you should be able to lay your head down and only hear your music. No one else should be able to hear your music. This is untestedd

The Build The audio feature is gained through a plate inside the pillow. You'll want some way to restrict the plate to the exact center of the pillow (and the back of it- the side more touching your bed) but still be removable. My idea is to sew a pillow specifically for this purpose..

The plate has a 3D Printed back to make the outline smooth in the pillow. You'll want to cover this with foam.

The Plate Use whatever is easily machinable- cut to an outline, and can vibrate. I plan to use Polypropylene, but the beauty of the system is how easy it is to switch to something else. Its just two screws (M4 flat screws) into two inserts (M4 8mm inserts)

Important Point on Plate Your use of washers is important here. You don't want the back to touch the plate (probably. I haven't built it) so put a washer in between the two, and on the front of the screw so you don't rip through your material- especially if its thin-ish polypropylene like me..

The Electronics

On the plate you have your electronics. They're all held in place with adhesive, and you'll need special adhesive if you use polypropylene plastic (plus rough up the surface first)

The electronics are simple. There is a Makerhawk Bluetooth Audio Module, a Pam8406 amp, and the exciter. You can actually use whatever exciter you want, even with this project, but make sure to match your amp and exciter- and unless you want to add boosters, make sure it can all run on the 5v that the Makerhawk needs.

Programming Included in this project is a small Python desktop app that pairs to the makerhawk and plays a spotify song on an alarm function. This is a little bit jank, and just for my purposes. As it stands you need your computer on all night for this to work. But if you want to use it, setup is wildly simple..

Important Electronics Notes

Don't just print the electronics enclosures and call it good. You want electronics shielding on everything- everywhere you can. You also want a capacitor on the Amp.
