About this project
Thank you so much, everyone for supporting us.
You took us through our initial target and you supported us when we set our first stretch goal, which we felt was pretty aggressive. And when we set our final stretch goal when we felt we were pushing the envelope, you joined in and you helped us there..... and then some.
Now, it is time for us to turn our attention to making sure that we can deliver your stuff in time. Follow the progress on our new forums by clicking below.
Once the Campaign has ended we will continue our support and reporting the progress of the project in our forums. The forums are for everyone, new users or if you're just curious, join in and make your voice heard.
Second Stretch Goal - Reached on the 31st of August !!
We have thought long and hard about it and we have decided to introduce a final rather aggressive stretch goal. Our engineering goals have from the start been to be able to deliver the best possible product to you as a supporter of our project. One point on the list of things that we have been wanting to do is to have the ESP210 module Fcc and CE approved. This is a costly and time consuming project, BUT If we can reach a 100.000 SEK before the end of the campaign we are in a position to do this as well.
So if you already are a supporter, tell your friends, co-workers, family, dogs and cats about our project about what we do. Every little contribution is highly valued.
If you are not already a supporter... what are you waiting for ? =) Its time to get on board.
First Stretch Goal - Reached on the 22nd of August !!
If we can reach the stretch goal of 60.000 SEK before the campaign is over we will add ready made expansion cables for all Adc4One and Io4One boards. In one end these cable directly connects to to the Adc4One and/or Io4One board and in the other end you can plug it directly in to a breadboard or a pin header connector. This is great both for quickly building prototypes and when connecting stuff inside boxes.
This project is about Connecting Your Things, nothing more, nothing less. Whether you are are an engineer building the coolest home automation gizmo to date, if you are just simply interested in knowing the temperature in the basement or if your spouse demanded a solar powered system that monitors the bird house and makes sure those small bird children are warm and comfy, we wanted to be able to provide you with the building blocks that would let you do this.... in a super easy way.
We wanted to create something that is as small, lightweight and easy as Lego to handle but that comes with the power of a big computer, that won't let you down in terms of storage space or performance. You really want that bird house to be secure, don't you ?
With the node.IT concept we think that we have done just that. A family of boards that ranges from a WiFi enabled controller board to A/D converter boards, I/O Expander boards Real Time Clocks and lots more that lets you create unlimited variations.
The idea of the project came to us late in 2014 and was to a large extent triggered by the introduction of the chip ESP8266, manufactured by the Chinese manufacturer Espressif.
Initially we tried many ideas of interfacing the device to other processors but we pretty soon found out that the processor that is already on board the ESP8266 is powerful enough to perform most required tasks. The early detours however gave us valuable knowledge about the device and its inner workings and the tools around it.
Instead we started to move in another direction and started to brake down what hardware components you normally would need to create things like alarm systems, environment monitors, surveillance equipment, irrigation systems...... and of course bird house monitors. We quickly realized that if we created a base controller with a minimum set of features such as the ESP8266, a USB to Serial transceiver and a simple voltage regulator you end up with a completely autonomous board that can be hooked up to a USB port and programmed directly, without any other circuitry.
This led us to the ESP210 module. A 27mm x 17mm module complete with everything needed to program the device and hook it up to wireless network.
The ESP210 includes all the necessary blocks that is needed to work with the device during development and/or in the final application. Multiple power supply options allows you to power the unit with voltages from 3.3V up to 7.5V.
As an example, with the ESP210 and a single MOSFET transistor we were able to create a speed controller for a model train within a few hours. After just another few hours we had created a system that we could push firmware upgrades over the air to the model. Imagine having an ESP210 for all the track switches, street lights, model house lights etc.
While the ESP210 module itself is very expandable, with easy access to all the GPIO's of the processor, it can be cumbersome to build some of the add-ons that you need your self. Here's where our +One and WorkStation boards come in, creating an entire infrastructure around the ESP210. The +One boards works very much like Lego bricks in that they plug on to the headers of the ESP210. The WorkStation boards can be considered the reverse of the +One boards in that the ESP210 plugs in to the WorkStation board. This way we can build add on boards that can build in every direction.
The base control board equipped with an ESP8266 Wireless LAN enabled micro controller. This module is equipped with 4 Mbyte of FLASH, an efficient voltage regulator and a USB to serial interface that allows you to upload code or communicate with a PC without having to connect any thing else but the USB cable.
A small number of +One boards have been defined and developed. These will be available when the ESP210 starts shipping and can be selected by choosing the appropriate reward. The list below has a short description of each board, click on the image to get to the Wiki for detailed technical information.
This is a Li Ion charger module with a controller that automatically charges the battery when needed.
An advanced sensor board with light, temperature, moist and barometric pressure sensors.
+One module with 4 extra GPIO lines with interrupt capabilities on each line.
A +One module with a 4 channel low power 12 or 16 bit A/D converter. You can add a total of two of these if you have a lot of analog data to collect
A battery backed up real time clock that comes with a unique EUI64 address.
A WorkStation board that expands your ESP210 with up to 8 analog (12/16 bit selectable) ADC channels, 8 normal GPIO lines as well as 6 Timer/Counter/PWM pins.
At the moment those are the +One boards that are defined and we want your help to bring more of these alive. Let us know what you want and we just might make it happen. For instance would you like to see accelerometers, MOSFET drivers, stepper motor drivers. Nothing is too crazy.
The ESP8266 device has good software support and there are at least three different SDK's that you can work with to create your applications.
We have decided to build our Ecoshpere around the Arduino IDE. So any software libraries that are required for +One or WorkStation boards or features required for the ESP210 to do its job will be developed for the Arduino SDK.
By using the Arduino IDE and its vast library of functionality you as a developer have endless possibilities when it comes to develop functionality for your systems. And with the built in 4 Mbyte of FLASH memory there is plenty of space to create file systems, web content, store sensor data and what ever you want to put there.
The node.IT project has its own github account (https://github.com/node-it) where you will find all drivers and other related software.
The node.IT system boards can be combined to build anything from very simple systems to advanced servers with display, buttons, a variety of sensors, memory cards etc. etc.
In this section we will try to give you a picture on what can be done by showing examples of what we do ourselves in our labs.
Example 1: - An environment monitor for our factory
Live charts from the example can be followed here.
Check out our wiki page describing the node.IT concept. It holds most information you need to get started and to see what you can do with all of this cool stuff.
Risks and challenges
In order to minimize any technical risks that we can foresee we have selected standard components as far as possible. We have been careful not to selected any exotic sizes that would be difficult to handle in production and the PCB's are all fairly standard.
Production will be done in our own production facility so we have full control over production schedules. Meaning that we can dedicate the full capability to this project should the need arise.Learn about accountability on Kickstarter
