Sip & Puff Using Raspberry Pi With Google Home

What we are trying to do is to open up the solution to all people with disability to work with us or other Makers, so that they can have a low-cost and effective design. And, can be able to build instantly, so rather than spending thousands of dollars for a commercially available Sip & Puff, the cost can be lower down which much more affordable for patients to support their other expenses.

We wanted to help, so we came up with the design of a device for people with disability to use and experience the power of automation. Our Sip & Puff switch is a breath operated device design to mount to all wheelchairs or desktop bound patient. We want to make our own Sip & Puff as an affordable solution by providing an Open source design using Raspberry Pi with an easy to build and available source of hardware assembly. This device will give people with disability more access in technology and more opportunities in digital connection.

I will post the source code here soon, if you want to add more features for this device you may do so..

Thanks everyone!

Raspberry Pi Product Overview

Product Details

Raspberry Pi 3 Model B+ is the latest computer board from Raspberry Pi. It is a development of the previous Raspberry Pi 3 Model B, offering improved speed and functionality. What is a Raspberry Pi? A Raspberry Pi is a compact computer board which offers endless opportunities. Simply plug in your TV, keyboard, mouse and power supply, and you are ready to go. There is a whole family of Raspberry Pi’s available to you, each providing various functionalities. There are also add-on boards available to enable other uses, such as camera and LCD display modules.The great thing about Raspberry Pi is that it is suitable for almost all age groups. Whether it’s introducing programming to children, or used by engineers to make complex computer-controlled systems, anyone can use one. Why choose Raspberry Pi 3 Model B+? If you’re looking for great speed and connectivity, the Raspberry Pi 3 Model B+ is for you. Whether you want to learn computer programming, or trying to incorporate Internet-of-things into your workplace, the B+ model can help you achieve your goals. It would be impossible to tell you everything that a Raspberry Pi can do as, with some help from add-on devices, there are no limits to your imagination. From media players to full IOT integration, education to gaming, monitoring working conditions to work productivity, and even controlling your own robot, Raspberry Pi covers a huge range of applications. The B+ features Power over Ethernet (PoE) functionality which works alongside the PoE HAT board (173-5595). So you can now power your Raspberry Pi board whilst providing Ethernet connectivity at with the same cable. Pi 3 Model B vs. Pi 3 Model B+ The new B+ board actually uses the same footprint as the previous B model and the Raspberry Pi 2. Therefore you can use it as an upgrade to existing projects or even use most existing cases. The new B+ model features upgraded board components to help your applications and calculations run faster and smoother. The B+ also features an exciting 64-bit quad core processor running at least 10% faster than the previous model. It also has improved thermal management. What’s on-board?
