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.

The DUO Travel is for hobbyists who want a device to program on-the-go, and is completely programmable without any external peripherals.

DUO Travel Hardware

The DUO Travel features a 16 by 2 character LCD, a 14 button keypad, an ATMega328, and 32 KB of EEPROM for program storage. The ATMega328 contains 32 KB of flash for firmware storage and 2 KB of SRAM.

The DUO Travel is powered by a standard 9-volt battery. When powered on, the DUO Travel draws 15 mA, and has an estimated battery life of 36 hours.

As an optional configuration, you can purchase the DUO Travel screwed into a hinged plastic case. The dimensions of the case are 5.5" by 4" by 1.4".

DUO Travel Software

The default firmware installed on the DUO Travel is DUO Travel OS. This firmware lets you write programs in a proprietary language called DUO Travel Code. This language is designed to be robust and easy-to-use.

DUO Travel Code features include:

  • Multi-character variable names
  • Arithmetic operators with order of operations
  • Floating point numbers, mutable strings, and lists with dynamic length
  • Custom function declaration
  • Global and local scope
  • Math functions and file manipulation functions

Here is an example DUO Travel Code program which displays prime numbers:

Why Kickstarter?

The DUO Travel has already been fully designed and is ready for production. I need a large number of preorders to keep the price of components low. Your funding will go directly toward the parts shipped in each computer.

Risks and challenges

This project relies on the availability of components from various suppliers. If the suppliers are out of stock, the project may be delayed. I will keep my backers informed if this happens.
