I will be creating a tomato design that will include an OLED display, a joystick for menu navigation and Neopixels around the design. I will fabricate two tomatoes, that will be able to communicate and set up a synchronous timer for group work.
My plan is to make the inside of the design by 3D printing to house the microcontroller and other brains. I would then surround the 3D print in Neopixels and make a mold to create a translucent silicon shell for the design so that the Neopixels will shine through. The neopixels will be green when the timers start and will slowly turn red as time develops and you reach closer to a study/work break.
When I started making this project, I made it with my girlfriend in mind. I wanted a way for us to both stay motivated while working, and thus designed the box in a way that meshed with her interests and motivations. Thus, I changed the design from a tomato-shape to a plant-pot holder since she loves plants and the environment. I also added other features to the design that I will discuss later that follows this trend.
What will it do?
It will set up timers for focused work time, and allow multiple people to create a shared timer
Who's done what beforehand?
There have been implementation of other Pomodoro timers, but none that I have found that include both hardware and creates a shared timer
What will you design?
A small tomato shape that will include microprocessors, LEDs, and a display
What materials and components will be used?
Electronics, soldering, CNC Milling, 3D printing, casting/mold-making
Where will come from?
I will be ordering parts off of amazon and digikey
How much will they cost?
Spreadsheet is attached here
What parts and systems will be made?
The outer body, the decals, the code, and the circuit boards will all be made by me.
What processes will be used?
I will be using 3D printing as an additive manufacturing method, desktop milling and vinyl cutting as methods of subtractive manufacturing, soldering, RFM69HCW chips for networking, and mold-making/casting for a diffuser for the Neopixel LED ring.
What questions need to be answered?
- Are ATiny3216s able to communicate via RFM69HCW radio signals?
How will it be evaluated?
It will be tested for functionality with individual timer usability, and if the radio communication between devices work
