What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Prototype Gallery

These photos and videos provide a detailed look at this project’s development.

We recently came across 2 excellent products. The Wemos D1 mini Arduino compatible wifi development board and the Nextion USART HMI display. Both of which are affordable, easy to use and powerful.  

Therefore, we have decided to build an IO board which combines the two to become a wireless display with touchscreen. It will serve as the backbone of our future projects and hopefully should be useful for many others.

Lots of IOs (GPIO, i2c, Serial) are available

Features:

  • Can be used as a standalone wireless touch screen display for Raspberry Pi or other IOT projects. Developers can use the Nextion design tools to build user interfaces and deploy onto the Nextion screen.  An API is provided out of the box to set values and get feedback from the HMI.  You won't need to write a line of Arduino this way. 
  • Can also be used as a weather station if you add the optional sensors, API is provided to read the data wirelessly
  • If you like to make modifications to the API, you are more than welcome to!  The source of the API will be open sourced during the delivery of rewards.
  • Fit nicely to the display. The PCB and the display screw holes fit perfectly. 
  • Can be used as a Arduino development board. All of the IO of the Wemos D1 mini are exposed and functionalities can be expanded, like adding thermometers and pressure sensors.

A few example of how it can be used:

  • As a wireless HMI - Use Nextion Editor to design the UI and deploy onto the display.  Connect the wireless display to your wifi network and use the pre-loaded http / mqtt api to control and receive input to/from display. You don't need to write any Arduino code.

  • As a weather station - Plug in the optional weather station pack sensors onto the board, connect to your wifi network and get sensors data via HTTP api.  You don't need to write any Arduino code
  • As a development board for your IOT project - Customise with your Arduino code and be creative.  You have access to Digital and Analog IOs / i2C and serial port.

Sample case #1 - Multi-location weather station

Sample case #2 - Raspberry Pi Server Farm Monitor

Another application we have built using Wireless HMI is this Raspberry Pi Server Farm, again using the API, no Arduino code is needed. Visit here for more details.

Risks and challenges

As you can see from the video and product demos, the prototype is pretty much working and completed state. Our engineering and development are very confident in delivering the product on time with satisfaction.

Possible Risks of delay:
- Unexpected manufacturing problems during initial production. We will ensure that they are found as early as possible to minimize delays
