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.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
My first project, Hackable Raspberry Pi Power Switch, was well received with 170 backers.
It’s now sold by more than 5 retailers world wide.
It’s a Raspberry Pi Power Switch with infrared remote which has an onboard programmable Attiny85 MCU. The main purpose is to gracefully turn on and off Raspberry PI with onboard power button and Infrared remote.
It was reviewed by MagPi, the official Raspberry Pi Magazine. It received a 4 out of 5 rating. I went back to the drawing board and improve further.
Introducing the Hackable Pi Switch HAT:
