3D Printed Cast/Prosthetic

Some time ago I started 3D scanning body parts and trying to print a diy cast that could be used anywhere in the world even if there is no hospital. This is the result! It is a nearly perfect fit to my arm. The Kinect camera does a great job- in the video you can see it even caught the contours of t...

Re: Arduino Cubesat (satellite) project

By popular request- here is the link to the files on my GitHub. https://github.com/MKme/Arduino-Satellite

Some solar panels just arrived so I may pick this project back up. I was hoping to laser cut a new frame but I cant seem to find a decent 1U laser template or SVG files. Still looking though.

iNav Telemetry with 3DR Radios

After DAYS of fighting I finally got the 3DR 433MHz radios to relay all the iNav data to my laptop.

https://youtu.be/XCQz9AeE2qA

This setup allows me to easily connect to inav with the PC in the air and send mission plans etc. I want to try HC12 modules or maybe LORA next :)
