3D Scanning & Project Tinkering

3D Scanning My Head

Hi everyone! This week was one that I have been looking forward to since the beginning of the semester–we learned about 3D scanning! I have always been intrigued by the capabilities and implications of 3D scanning; it is so cool that we can use cameras/sensors to scan a physical object and create a digital representation of it. We learned about some different consumer-level 3D scanning products and were able to test one out that we have in the lab (we have an iPad attachment). Each of the class members scanned a bust of their head. We were then able to load these files on TinkerCad and fill-in/smooth-out any imperfections in our scans. We then put the edited files into Cura so we could obtain .stl files to then send to the 3D printers! Check out my Cura model and final print below:

A fun fact that I learned was that the Xbox Kinect sensor has the same scanning capabilities as the 3D scanners that we talked about in class. This was exciting for me because I have an Xbox Kinect sensor at home! The way it works is the Kinect sensor gets connected to a computer and we can then 3D scan an object with the proper software installed!

Project Tinkering

My group is waiting on one of our parts (the 7-Segment display) to come in so we can dive into the building of our prototype. However, this did not deter us from making progress on our project this week. We each performed different parts of our research needed, and I also started tinkering with our perfboard and wires (see picture below).

Perfboard/wire tinkering

The picture may look overwhelming with the wires, but this exercise was actually very beneficial in helping me understand the use of perfboards. Physically maneuvering the wires along the board allowed me to see where the different ports connect and which positive/negative currents would be affected by certain connections. I feel much more confident moving forward in the coming weeks when it comes to connecting our 7-Segment display and sensors.

One additional update that we have for our project is that we are going to utilize a push button counter instead of a sensor for our first prototype. This is because we want to be sure that our 7-Segment display is going to work with our creation before we dive into the depths of coding. Utilizing the push button will allow us to ensure that our prototype is properly created because we will be able to see our number on the display go up and down as we knowingly push the button. Alternatively, it would be more difficult to see where our prototype is correct/incorrect if we use the sensors right away because it would be harder to narrow down if an issue is with the sensor, coding, or wiring of our prototype.


Extra Note

While my group’s project most likely will not require soldering, I found a useful video on YouTube that gives further insight on this topic incase we any group does: https://www.youtube.com/watch?v=3N3ApzmyjzE. This video was beneficial because it allowed me to see how another individual used a perfboard and made his own creation. The more that my group learns about these boards and their different functionality, the better off we will be in using our creativity to make the best possible prototype!


Thank you!

Thank you for tuning in this week. More project updates are to come next week once we have all of our parts!

  1. Scott, it sounds like your project is coming along quite nicely! There seems to be a lot of detail and hard work going into it, which I also witnessed first hand in class last week. I also have an Xbox Kinect at home so it was exciting for me to learn that the same technology is being used in my class!

  2. Hey Scott! I love seeing your Cura file turn out so well! I think your scan was one of the best that was taken. I totally agree with your rational to do the push button first then dive into the code and laser sensors. I’m glad we got the code uploaded to the board this week, though!

  3. Hi Scott,

    Thanks for sharing the final product of your 3D scan- it looks great! I had no idea that the Xbox Kinect utilizes similar technology. I figured that it would definitely have some sort of edge detection capability, but I was really surprised to see from the video that it’s possible to do a full scan as well!

  4. Hi Scott- I was also looking forward to learning about 3D scanning all semester. Seeing scans of people around the room and having learned about different products that were made because of 3D scanning made me excited to try it out. The likenesses of the busts we printed were uncanny- my friends think mine is extremely creepy looking, but they all agree that it looks just like me.
