Introducing MRT 360° – Multipurpose Rotary Table
Some time ago, I designed the first working prototype for myself and was thrilled with it, using it constantly for content creation. However, that version wasn’t perfect. It required extensive soldering and programming, which could be challenging for many users.
But let’s start from the beginning…
MRT v1.0
Version 1.0 was purely a proof of concept – at the time, I wasn’t sure if everything would work as I had imagined. I built the device using ready-made modules, including voltage regulators, a battery charger, a stepper motor driver, and an Arduino Mini board, which helped test the concept quickly. I also left extra space in the 3D model to allow for modifications, making it easy to refine using tools like a Dremel or a knife.
I made adjustments to the project by adding a hole in the 3D-printed base to install the potentiometer, making it easy to control the table’s rotation speed. Additionally, I developed a simple program to control the MRT.
My main reason designing the MRT was to expose my other designs ( for example PETmachine) which were too bulky for standard rotary tables available on the market. The second reason was simply my love for designing functional devices!
MRT v2.0
I wanted to share my project with everyone, so my next step was to improve it by making it more organized and easier to assemble.
I cleaned up the wiring, removed an unnecessary voltage regulator, added a button for controlling the rotation direction, changed the position and size of the power switch, relocated the potentiometer, and made the table wider and thicker for improved stability and usability.
However, soldering and programming were still required to successfully build the MRT.
MRT v3.0 (The Latest Version)
For the latest version of the MRT (v3.0), I aimed to make the assembly process even easier. I collaborated with my friend Łukasz Wudarczyk to design a custom motherboard that integrates all the necessary components in one place, and the ESP32 module will be pre-programmed. This eliminates the need for soldering and programming, making it accessible even to beginners.
Other components with pre-crimped wires, such as button, potentiometer, battery plates and stepper motor, can be easily connected to the motherboard using JST connectors. The motherboard features an ESP32 module, enabling Bluetooth functionality used in automatic mode.
The first prototype of the motherboard had some bugs and issues, which will be eliminated in future version.
The 3D model of the MRT main body had to be redesigned to create space for the new motherboard.
The MRT v3.0 can be easily integrated with a dedicated, fully 3D-printable lightbox ( equipped with 5V LED light strip), greatly enhancing the device’s capabilities.
MRT v3.0 – main features
- Manual mode (control rotation speed using physical knob);
- Automatic mode (connect your phone to MRT via Bluetooth for hands-free 360° photos);
- Built-in battery and USB-C charging port;
- 3D models and instructions prepared to provide an easy and pleasurable assembly process;
Manual mode
Simply turn on the device, and it will be in manual mode. You can control the table’s rotation speed using the SPEED knob or turn the rotation on/off with the MODE button. It’s perfect for creating video content!
Manual mode is ideal for those who need full control over rotation speed, allowing creators to adjust the table’s movement to suit their specific shot or content requirements.
The MRT offers great capabilities even without the lightbox. When the object doesn’t fit inside the lightbox, you can easily use your favorite studio setup to showcase the object.
Automatic mode
With automatic mode, you can easily capture 360° images for product displays or social media content – perfect for anyone looking to showcase their creations or products in stunning detail.
To use the automatic mode:
- Connect your phone with MRT via bluetooth,
- open system camera app,
- set your object on the MRT table,
- turn the SPEED knob to the extreme left (4 pictures) or right (8 pictures) position,
- press the MODE button and watch the shoot!
Using free background removing tools you can get incredible results!
In this way you can create high quality content for your website, social media or online store – everything with ease!
Built-in battery and USB-C charging port
With a built-in battery that lasts 2-3 hours of continuous use, the MRT lets you capture a full product shoot or video session without needing to recharge.
At startup, buzzer beeps indicate battery level:
- 1 beep = 0-25%
- 2 beeps = 25-50%
- 3 beeps = 50-75%
- 4 beeps = 75-100%
You can recharge the device at any time using a USB-C cable.
