Idea 1: Refine the lamp from Sinclair’s class
My first idea is to build on the lamp I previously made in Sinclair’s class. The plan is to 3D model and enhance the hand-crafted parts, making them more functional and refined. I’ll add a lighting function that can be customized for different moods.


Idea 2: Therapy pet toy
Inspired by the talking bass, I’m creating an interactive pet plush toy that responds to sound. I’ll create mannikin and patterns for the appearance (maybe using AI modeling to do that from a photo of someone’s dog), tear down a walking dog toy to reuse the gears, integrate a Bluetooth receiver and speaker into it. It will allow the toy pet to chat with its owner as if it can do therapy, and companion the owners with body movements.

Idea 3: Interactive Pet Memorial Urn Light
For pet owners who want to keep a meaningful connection with a beloved pet, this interactive night light offers a unique way to honor their memory. The plush toy contains a small box inside to hold pet ashes with herbs to preserve it, and can light up as a bedside companion. When you call your pet’s name, a warm-colored breathing light will glow, creating a sense of presence and companionship. (maybe add a speaker to it so that it can play a recording of the pet’s vocal sounds.)

Lynn, these are all amazing ideas! Great brainstorm. I can’t tell you which one to pick, but can offer some recommendations for each idea:
1. Lamp
Where would the LEDs go? And the microcontroller? What is the user experience like? You could use capacitive sensing to make the metal part of the lamp touch-reactive. Here are some examples:

2. Therapy pet toy
This sound board: https://learn.adafruit.com/adafruit-audio-fx-sound-board?view=all is perfect for this project, if you want to playback pre-recorded sound. get one with amplifier if you intend to connect speakers. you can trigger this sound board using serial or a digital output from your Arduino, based on audio volume sensed using a microphone connected to an analog input. Here’s a microphone that would work:

or https://www.adafruit.com/product/1063
If you want to control the playback remotely, here is a project that does that over bluetooth:
https://learn.adafruit.com/phone-activated-talking-dog-collar but you could use the same concept to control it over wifi as well.
I also want to show you a more advanced project that actually talks back https://www.youtube.com/watch?v=_yApuo9uIGY
3. Interactive Pet Memorial Urn Light
This is a sweet idea. Speech recognition is pretty complex, but my buddy Shawn has a tutorial about it:

I’m happy to chat more about any/all of these, just reach out on slack or email.
