My projects.
I am attending Idaho State University as an undergraduate in the College of Science and Engineering. I am pursing a degree in Electrical Engineering. I will be holding my projects here on this website. My projects will be updated over time.
In high school, I attended a state-wide drama competition with this Sorting Hat replica that I had made out of an old coat. On the interior of the hat, I had foam to hold its shape, tongs to control the mouth as a puppet, and a speaker with pre-recorded audios I could play from my phone via Bluetooth.
I purchased a Raspberry Pi 5, 8GB model for this project. I opted for the 8GB model to allow for faster response time by the AI models. The amplifier, speaker, and servo motors are being run by an ESP32-S3. The ESP32-S3 will listen when the button is pushed and stop listening when the button is released. After it finishes recording the audio, it sends it over WIFI to the Raspberry Pi 5. I have a server hosted on the Raspberry that then sends the audio file to a Whisper AI model to transcribe the audio. The transcribed audio is then used as a prompt to the “Sorting_Hat_brain” model which follows a Python script to stay in character and then generates a text response. That response is then sent to another AI model that generates a voice response from the text response. That new audio file is sent through WIFI back to the ESP32-S3 and played through the speaker.

Electromagnet Thor’s Hammer
Thor’s Hammer is one of those items everyone is curious about. How can no one but Thor pick it up? How can it summon lightning? While I may not have magic, I do have engineering. This project was meant to be a way for me to put what I’ve learned in university to practice. Inside of the hammer, we have an electromagnet and a battery pack. I started with a NC button to turn off the magnetic field and allow the hammer to be picked up. I quickly realized a button is too easy for a bystander to become “worthy”. I have used RFID tags in many other ideas and decided I want to try this as an approach to determine who can pickup Thor’s hammer. I now have an RFID card connected with an ESP32-S3 which runs the logic to see if the correct RFID tag is read and only then does the magnet turn off. To save on materials, I could use a smaller ESP32 model. I have a transistor in place to help the ESP32 logic pins control the current of the magnet. Otherwise, the magnet could ruin the ESP32.
