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.

Compatible Arduino’s

The Sunflower Shield is compatible with a wide range of Arduino and Arduino clones, however there are some which are not compatible. The Sunflower Shield requires 5V to be supplied from the Arduino itself, and some Arduino clones, specifically 3.3V versions such as the Arduino Pro 3.3V, feature 3.3V on the pin typically specified as being 5V. These 3.3V varieties are not compatible as 5V is required for the Sunflower Shield itself.

Known compatible Arduino’s for the Sunflower Shield: 

Uno, NerO, Leonardo, Mega 2560

(Others may also be compatible.)

Shipping

We will ship all Kickstarter rewards globally from the United States of America by using a registered parcel costing approximately $9 USD for domestic and slightly more for international.

Any import duty or VAT is the responsibility of the backer, whom we assume is an individual rather than a corporation.

Please note that we can ship to most countries with the exception of Argentina, Cuba, Iran, Iraq, Lebanon, Libya, Myanmar/Burma, North Korea, Somalia, Sudan, Syria, Ukraine, and Yemen.

Risks and challenges

In order to reduce the frustration of backers, we chose to work ahead of time and made sure that the project was as close as possible to mass production before launching this Kickstarter campaign. The development and tooling costs are paid for and the funding required is purely to cover the costs of the production runs.

Here are some potential risks and how we plan to address them:

Business, Budget, Finance:

We decided to launch our Kickstarter the "right way" by forming an LLC, obtaining a tax ID, and business banking services. We have a budget, modeled our potential income, identified pitfalls, created wiggle room within our budget, and have spoken to several different successful Kickstarter launchers about what problems they ran into.

Electronic Hardware Production:

All project members have experience in electronic production and assembly, and have used contract manufacturers in the past to produce commercial and non-commercial electronic products. While we do not claim to be experts, we know what it takes to successfully take a design from an idea to full production.

We have suppliers lined up, and to the best of our knowledge, should be able to deliver without any problems.

In summary, we believe the risk in backing this project is extremely low.
