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…

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…

I wanted this to be an art piece more than functional.It features a water fall mechanism which moves around a spout, via a stepper motor and pulley system (seen on the upper hub with spokes and teeth…

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…

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.
