Hospitals are much too loud for recovering patients to rest properly.
Our team designed this system with that in mind - a restful environment is a healthy environment.
This project is affordable ($50-30) and easy to use. Let's get rested!
Step 1: What You'll Need (the Pi)
Shown is a Raspberry Pi (with an SD card), a Wi-Fi USB and the Raspberry Pi power chord.
Our current project uses the Raspberry Pi 2B and a Canakit Wi-Fi USB 'dongle', but any iteration of Raspberry Pi will work, along with any universal Wi-Fi USB jack. If it says "Raspberry Pi compatible" in the product description, it'll work.
Step 2: What You'll Need (the Mic)
We found that any USB microphone will work- but it's always nice if it says "Raspberry Pi compatible" in the product description :D.
For our project, we used a USB with a headphone jack-soldered Mic we tore off of something else.
This was just for research purposes.
Step 3: What You'll Need (Computer Tools)
Any USB mouse and keyboard, and any screen with an HDMI input chord.
We used a Logitech wireless keyboard & mouse with a single USB jack.
Peeking in from the right is a HDMI cable (hello). It was connected to a TV and a desktop monitor.
Step 4: Getting Pushover
Go to Pushover.net and create an account.
Then, go to the applications tab and create a name for your future Rest Egg (we named ours The Rest Egg).
Copy down the user code and the application code (I emailed them to myself).
The Pushover logo is a trademark of Superblock ,LLC. All rights reserved.
Step 5: Getting Raspberry Pi Running
Go to https://www.raspberrypi.org/downloads/raspbian/ with your SD card inserted into your home computer.
Follow the directions for your computer type (i followed the mac instructions).
After loading it all up, insert the SD card into the Raspberry Pi, along with the USB keyboard and mouse, the USB microphone, and plug in an HDMI chord connected to a TV or monitor. Whew.
Last, plug in the Raspberry Pi.
Follow the on-screen instructions. You should see the above screen after you're done.
Step 6: Getting Rest Egg Running
Check out our Github at https://github.com/RestEggASU/TheRestEgg
Drag RestEggAudioAlert.rb into your Pi folder (located by first click on the little filing bin).
Drag OneLiners onto your desktop.
Paste the needed user and application codes into the correct portion of the RestEggAudioAlert.rb file.
Open LXTerminal; copy and paste the code at the top to run the program with the listed numbers.
Clap into the microphone. A message should appear, and an alert should arrive to your Pushover.net account.
Download the Pushover application on any device to have these message appear while you're away from your computer.
Step 7: Possible Cost Savings
The previous purchases seem too expensive?
If the Raspberry Pi Zero is available to you, order these other devices and you can create the RPi Zero-version of the Rest Egg for around $30. Plus, you can say you have a $5 computer the size of a stick of gum.
