This is a DIY Ghost Box like the Ovilus ghost hunting device. While I don’t believe in ghosts, I do think ghost hunting gear is fascinating. This box chooses words out of a 1000 word dictionary based on magnetic field and temperature changes. The code is available for free on GitHub: https://github.com/kevinl95/ghostbox
Electronics:
1x Adafruit Feather M4 Express (If substituting, make sure you either buy a board with a DAC for the speaker or build one)
1x Adafruit 9-DOF Accel/Mag/Gyro+Temp Breakout Board – LSM9DS0
1x Adafruit Illuminated Toggle Switch with Cover – Green
1x Adafruit Thin Plastic Speaker w/Wires – 8 ohm 0.25W
1x Adafruit Lithium Ion Battery – 3.7v 2000mAh
CAD and STL files can be accessed from the Thingiverse project page!
Adventures in Problemism 
Kevin,
Tried to start on your version of the Ovilus, but in the code, can’t find the file “english.h”. Can you point me in the right direction?
Thank You

Sorry about the late response- it comes from the Arduino Text to Speech library which is a dependency: https://github.com/jscrane/TTS
This will also get you TTS.h and sound.h
