Sleep, it turns out, is one of those things we all need. And we need a lot of it. So anything that can be done to help out sleep can help out our health, long term. Here’s more from Elite Worm:
This is a tiny electronic device I designed to fix my morning neck pain. This first version is based on a cheap ATtiny85 microcontroller, but after having some trouble with the limited amount of inputs and outputs available during the designing phase, I might switch to an ESP32 in the next revision. This project is meant to do something really simple, yet crucial! Every night, I tend to unconsciously switch my body to a position that feels comfortable but causes some stress in my muscles. That leads to having a sore and stiff neck morning after. This device has some nice features such as a mini vibration motor, an electronic switch, and a 3.7 V LiPo battery with an onboard charger. This time, I used 0402 sized resistors and capacitors, just to maximize my space.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
