    Home Control

    This model includes an ESP-32, an I2C OLED display, a hall-effect sensor, and an endstop/button. The fun challenge I implemented in this design was building my own encoder wheel solution. For this I created a wheel which had a series of embedded magnets in the perimeter. Using a Hall effect sensor mounted next to…

  • HDD External Mount

    HDD External Mount

    This model allows for 3 hard drives to be mounted vertically and in the open. This was an admittedly strange necessity for me; however, my server chassis has been entirely filled with other components, so I had to move the hard drives outside. I wanted them open so they could receive passive cooling from…

  • Dense Sample Holder

    Dense Sample Holder

    In my lab work, we produce hundreds of samples to be tested. Traditional sample holders take up lots of space, so I designed this portable sample holder. It comes in two sizes (10 or 5 sample trays)The sample trays slide into a storage box that can be screwed tight, with a lid that has…

  • Angled Bowl

    Angled Bowl

    This is an example of Fluid forms, which are traditionally a challenge in CAD software. This was done in Autodesk Inventor as an exercise. It fits a standard dog food bowl and keeps it at a 15-degree tilt. This is what I use as a catch-all in my home.

  • Burrito Feedo

    Burrito Feedo

    The Burrito Feedo is the solution for a my very hungry cat. Available automatic cat feeders had two main problems for me 1. They don’t actually measure the food weight, just activate a dispenser for a set time2. They are always automatic, meaning the cat won’t recognize you as the provider of food. To…
