stresslet

This was a project I worked on with my friends for the STEAM Tank project in May. We made it to the finals and won a couple of awards for our design!  Our CADDed design^^^ the circuit would live inside the large "mother" bead in the middle.  I designed our circuitry prototype--from our schematic to the basic breadboard version. It's a bracelet that reacts to stress-- the first of its kind because bracelets like these either only focus on reacting OR monitoring to stress but we do both! Furthermore, we made it stylish and added many personalized response mechanisms so that it can be used effectively in every day life.  1) Schematic The circuit has a few different parts: There's a microprocessor that controls which "response" mechanism is getting voltage depending on the stress levels recorded and sent to it by the Pulse Sensor-- a premade monitoring Heart Beat monitoring part found online. The response mechanisms would be an LED that would tell the user to op...

the music box

 11/7/24 Just a couple weeks ago I created a macropad that would accelerate music for music lovers as part of the hackpad challenge.  It included three components: PCB design, 3d case CADing, and firmware.  1. PCB design:  Designed schematic on kicad first.  Conversion into PCB design. (This is a 3d view).  Has three keys (pause, forward, play backward) and one OLED that displays the song name. 2. Case CADing  It took a bit longer than I would have liked to figure out how to move things in fusion. 3. Firmware  There are still some glitches I have left to fix here.  Things I want to improve:  *Maybe make one of the keys a shortcut to Spotify? App cuts take time and I had a time crunch but maybe next time? *Firmware can be more thought through  Things I liked:  *The CADing came out nicely : )
