A Future Kit stereo headphone amplifier built into an ordinary deodorant stick bottle. I was worried to turn it up all the way as it could break my headphones; although you couldn’t tell in the video, it really does get THAT loud!
-9V battery
-on/off switch
-stereo input/output
-Volume Control (I used the dial that would normally be turned to push out the deodorant)
This project was done for IEEE in Stony Brook University.
