A small simple device to help users fall asleep. The Sleep Coach was designed to be easy to manufacture, and the design and code are open source (see license at bottom).
- Creates a pattern of light that you match your breathing to
- Breathing rate is decreased during sleep, so this helps ease you into sleep faster
- The maximum brightness can be adjusted on-the-fly using the wheel potentiometer on the back
- One-button operation
- Set up the sleep coach on a night stand or table next to your bed.
- Turn on the sleep coach and adjust its angle to either shine in your eyes or on a wall or ceiling.
- Begin coaching, and match your breathing to the pattern of light
- Fall asleep faster!
I have been conducting a study to collect data on the Sleep Coach to see if it actually helps users fall asleep.

So far I have had great success with the sleep coach, but I only have a sample size of 5 users. I'm always looking for more study participants!
- ATtiny85
- 8 pin DIP socket (recommended)
- 1-sided copper board
- 330Ω resistor
- 10 mF capacitor
- 4 red LEDs
- Tact button
- Wheel potentiometer
- Battery holder for 2 AA batteries
For my version of the mechanical design:
- 3.5" 1/4-20 bolt
- 1/4-20 wing nut
