Python on a Raspberry Pi Pico

As I'm learning Python and Micropython to ultimately write code for Dynamo for AutoCAD and Civil 3D, I'm playing with some basics. Writing Micropython for a Raspberry Pi Pico to read temperature and humidity then display the readings on a 16x2 LCD screen. My plan is to mount the setup in my network home lab to see the temperature inside the cabinet. I will 3D model and 3D print a mounting bracket for screen and Pico. Cool things to come.

Raspberry Pi - Cyberdeck

 This was a fun personal project. I created a 3D printed case for a Raspberry Pi 5 and a 7” Raspberry Pi Touch Display 2 screen. The case was modeled in AutoCAD using solids and 3D printed on my Bambu Lab X1 Carbon printer. The back panel was modeled with keystone inserts so I can use various keystone jacks for the rear I/O. The rear I/O consists of ethernet, USB and HDMI. I currently have a 3D Printed mouse in matching colors and a small keyboard. My plans are to use it for motoring my Unifi home network lab, home automation and media streaming box. I also plan to create a miniature stop light setup and controller using Python and Scratch. Learning Python should be fun. Enjoy!

Stafford County, Va. Road Project 360 VR Animations

 Here are the two 360 degree VR animations I created for a Stafford County, Va. Road Project. The model was built with a land surveyed surface, Civil 3D corridors, pipe networks and so on. I then brought everything together in Autodesk Infraworks then Autodesk 3D Studio Max for a little cleanup. I then imported the model into Epic Twinmotion. Rendering was processed on a BOXX Technologies rack mounted workstation with an Intel CPU and single NVIDIA 5090 GPU. Each video took about 18 hours to render. I then had to inject 360 metadata in order for YouTube to see the video in 360 degrees.

Click on a video then use your mouse to pan around. The videos can also be viewed in a VR headset. Be sure to change the resolution to 2160, 4K for best results and viewing experience.

AutoCAD 2026!

 AutoCAD 2026 has hit the shelves. Time to play with the new features.

Intersection Animation

 Here is an intersection I'm working on. It's built with AutoCAD/Civil 3D. The flythrough is created with Epic Twinmotion. I hope to have buildings added soon.

3D Modeling in AutoCAD for 3D Printing

 Here is a short tutorial on 3D printing AutoCAD 3D models.

Christmas Ornaments

 I'm drawing and 3D printing Christmas ornaments. They were modeled in Autodesk AutoCAD and Fusion 360. I used the 0.2mm and 0.4mm hotend assemblies on my Bambu Lab X1 Carbon for printing.

Autodesk University 2023 3D Printed Chip

 I created an Autodesk University chip I plan to hand out during the week of AU. I used AutoCAD solids to create the model. As for the QR code, I converted the QR code image to DXF and cleaned it up in AutoCAD. I tested the QR code with my smartphone while in AutoCAD and then in the Bambu Lab Studio slicer software. It worked so now to 3D print the model and test the QR code. I used Numakers PLA filament in three colors. The QR code works but I feel it can be improved. More to come!

Here are a few updated 3D prints. I used a 0.2 mm print nozzle for better accuracy. The downfall, it took twice as long to print compared to using the 0.4mm print nozzle.

3D Printed Miniature Traffic Control Box

I created a miniature traffic control box for a co-worker who is into miniature LED stop lights. The box will house the electronic controllers for the LED stop lights. The model was created in AutoCAD 2024 with 3D Solids then exported to a stereolithography (STL) file for slicing in the Bambu Lab software. I used yellow Numakers PLA+ filament. Total print time was around 14.5 hours. I had to make a few adjustments to the print speed and temperature to use the Numakers PLA+ filament.

Autodesk University - AutoCAD & General Design

Thanks to Autodesk for featuring my class on the main AutoCAD & General Design page.

Bambu Lab 3D Printer

My Bambu Lab X1 Carbon 3D printer has arrived. I test printed the Benchy boat. Everything looks good and printed fast. I'm looking forward to printing my CAD models. Stay tuned!
