3 thoughts on “Bethany’s Final Project Brainstorm”

  1. Bethany, I love your sketches. Consider submitting them as part of your final dossier, and using them as a website wallpaper, etc.

    1. differentiating sounds (frequency detection) with arduino requires some advanced coding using FFTs (fast fourier transforms)– it’s outside the scope of what you’re expected to know, coding-wise. More info: https://learn.adafruit.com/fft-fun-with-fourier-transforms

    2. Is this device to keep you from scrolling in the middle of the night? Or to stop folks from bothering you? Either way I guess I don’t see why it needs to be a physical device, rather than an app that locks down functionality on your phone (maybe more possible on Android than iOS). Project is feasible but doesn’t sound super fun to me. lock-style solenoid: https://www.adafruit.com/product/1512 featherwing seven segment display in red: https://www.adafruit.com/product/3108

    3. wifi signal strength detection isn’t officially supported with the ESP8266, though the web says it’s available by digging deep in to the closed source docs. hard pass.

    4. motion triggered light is completely feasible, you can use the PIR sensor from your kit and take a look at this audio fx board that is easy to trigger from your arduino: https://www.adafruit.com/product/2217 (needs a speaker too)

    5. mood mirror is totally feasible, but better with bluetooth than wifi. I’ve used this one before: https://www.adafruit.com/product/2829 but there is a cheaper one here that should work the same: https://www.adafruit.com/product/3406 . However you’d be using the Adafruit Bluefruit LE Connect app and picking a color or clicking a button labeled 1 2 3 or 4 (or up, down, left, right), no custom interface for selecting a “mood” with an associated color. It’s an ok conceit as far as I’m concerned, but you may not like it.

    6. motivational clock is totally feasible using IFTTT and IoT class lesson 4’s code. Not quite sure why this has to be a physical device rather than an app, but i’m sure you could think of some reason (maybe it plays sound samples like your idea #4, maybe it also sends motivational stuff to others when you press a button on it, etc. etc.)

    Please let me know if you have more questions or need further help in choosing.

  2. Thank you for the feedback, Becky! I was busier than I thought after talking to you this morning, so I didn’t get the chance to make sketches for my other ideas, but I’ll summarize here:

    7. Shirt or other clothing item with graphic (cup or battery maybe?) that gradually fills up with light as you get closer to reaching your steps for the day.

    8. Introvert Meter: Wristband, necklace, or other wearable that tracks your social interaction through listening to ambient noise, and texts you when a set maximum amount of interaction has been reached.

    9. Wallet that locks itself when your bank account drops below a set amount of money to stop you from spending.
    OR 9.5 Wallet that transfers X amount of money to your savings account any time you open it

    Please let me know if any of these seem better or more feasible to you than my previous ideas!

  3. Hi Bethany, these are also fun ideas!

    7. fitbit is supported by IFTTT, but not sure if you get granular data about approaching your goal or just meeting it
    8. feasible, here is a microphone: https://www.adafruit.com/product/1713
    9. this idea reminds me of this project: https://consumerist.com/2010/12/07/smart-wallets-react-to-electronic-spending-by-refusing-to-open/ Bank account projects are tough because of all the authentication required to connect to banks. Stocks and mutual funds work through the Finance IFTTT service, and auto-savings can be accomplished with the Qapital service. For detecting wallet-opening, you could use a light sensor like the one in your kit.
