Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Flex Box – Modular Storage Organizer Box System #3DPrinting #3DThursday

benjaminkott shares:

This flex box system is an evolution of my original organizer box, but it’s not just a version 2 – it’s essentially a completely new model. While it shares similar size ranges with the original, the scope has expanded so much that it deserved its own release. The dimensions have been reworked with fine-tuned spacing and sizing for a more controlled, predefined set that enables multiple decorative hole patterns

Simulate Thermal Performance in Autodesk Fusion

Autodesk Fusion shared this video on Youtube!

Learn how to perform a thermal simulation in Autodesk Fusion with this step-by-step beginner-friendly tutorial.

In this video, Autodesk Certified Instructor Elizabeth Bishop walks you through how to run a basic thermal study to evaluate how your design performs under heat conditions using the Simulation workspace of Autodesk Fusion.

You’ll learn how to set up a thermal study correctly, analyse heat transfer in a real model (pipe example), test whether your chosen materials can handle thermal conditions and understand practical use cases like cooling fins and insulation.

This video is perfect for engineers, product designers, and students who want to validate designs using FEA thermal analysis in Fusion.

The TI-84 Evo graphing calculator

The TI-84 Evo The TI-84 Evo is a next-generation graphing calculator featuring integrated Python programming, a 3x faster processor, and a USB-C port, designed to replace the TI-84 Plus CE Python. It includes an icon-based menu, a larger graphing area, and supports both Python and TI-Basic for coding. It is approved for major exams, including SAT, ACT, and AP.

It features an ARM Cortex CPU running at 156 MHz, delivering 3x faster performance than previous models, along with integrated Python programming via a USB-C port.

Includes built-in CircuitPython support, allowing users to write and run Python code directly on the calculator.

It acts as a successor to the TI-84 Plus CE Python which used a separate ARM Cortex M0 co-processor. It offers a faster, refined experience with a new icon-based user interface.

A broken bike sync led to reverse engineering Wahoo’s hidden debug mode

Noah Clements’ bike rides stopped syncing to his phone. That was it. That was the whole reason he ended up reverse engineering Bluetooth packets, decompiling an Android APK, and getting greeted with “WELCOME TO HELL DEVELOPER” on his cycling computer.

I ride a Wahoo ELEMNT Bolt v3. It’s a solid GPS cycling computer – maps, sensors, the works. But at some point my rides just stopped syncing to the companion app on my phone.

The Bolt v3 runs a custom Android build.

See how Noah dug through the code, found the developer menu and ended up documenting the full BLE protocol, the file transfer system, and more.
