I have an idea for a project, a washer dryer detector.
Like most homes there washer dryer are in the basement. You go down there and put your laundry in them and wait for them to beep right. Well it’s like the tree that falls in the forest. Does it make a sound?
What if we made a tone detector that listens for the two different beeps and sends out an alert. It could be like an Alexa skill where you could say “hay Alexa tell me when the washer or dryer are done” and it response with “OK”. Or you could have an app on your phone that sends you an alert that your dryer is done and if it’s connected to your activity tracker or smart watch your wrist would buzz.
Now the problem is you forgot you put the laundry in and you’re at the mall shopping, oppose.
We could have Ken make an info commercial and sell them for 3 easy payments of 19.95, no wait for a limited time get two units for the same price just pay shipping and handling. We could call it the Clap on Clap off for the washer dryer. Ok maybe we need someone more upbeat then Ken.
We have most of the hardware needed except a way to detect the beeps coming from the washer dryer. You could wire something into the washer dryer but that would mean taking it apart and messing with the wiring and every washer dryer is different so that might not be a good idea.
So we need like a telephone encoder that can take sound and convert it to an 8 bit value that we can process. From there we use a Parallax WiFi module to connect it to our network and send out an alert that is picked up by an app. They always have an app for that right.
So the question is how to detect the beeps if no ones in the basement since it might not make any noise.
PS: we could also add in a water detector so when things overflow. I have one of those things that you set on the floor and it beeps when it detects water.
