Powering micro-controllers by Battery

Working with low-power applications, one of the most common topic are batteries. Questions like “Which one is the best battery?” is a very common one. We all know that there’s not a single answer for such question, and this post will explore the different options as well highlight the weakness and strengths of some common kinds of batteries.

Although this is can be considered a generic battery post, it has been written having low voltage micro-controller applications in mind, more specifically solutions like our Whisper Node product.

So the question the post tries to answer is: “Which is the best battery to power my micro-controller application?”

InfluxDB + Grafana for the IoT

Hello everyone, it has been a while since our last post. The Kickstarter campaign has proven to be quite involving, but things start to get back to normal and new posts will keep appearing.

As now we’ve an official product/platform, there’s a plan to start creating practical posts, complemented by video blogs to show real use cases step-by-step. Stay tuned!

Moving on, this post will present a very promising solution to store, presenting and analyse time series data. Perfect to save all the IoT data produced.

Connecting to the Internet

Talk² is all about communication and adding Internet connectivity to your project can easily bring it to the next level! Despite the fact that you can find a couple of alternatives to it, we would like to present our prefered way.

On this post we’ll briefly check the common ways of connecting an Arduino to the Internet, evaluate the Pros and Cons. After we’ll present the Talk² approach to this problem, explaining concepts and queueing techniques to build a much more robust and flexible solution.

The popular options

After some research we easily concluded that the most popular way people are connecting their Arduino to the Internet is by using a direct Ethernet connection. Some cases using shields or expansion modules, others by simply relying on the build-in Ethernet capabilities of the board/MCU.

Meet Talk²


Say hello to Talk², or Talk-Two or Talk-Square!

Today is our first post and we’ll explain a bit about this project. Before starting, feel free to follow us and leave you comments or suggestion. We’ll try to keep all details about this project as much up-to-date as we can, as well reply to any question you might have.

First come first: What is Talk² ?

In a sentence: Talk² is a microcontroller development solution with build-in communication capabilities. But in reality it takes a bit more than that to explain all the features and the problems it tries to solve.

You may noticed, we used the term development solution instead of development board, that’s because Talk² is designed to be a platform independent solution. In the real life it means that you’ll be able to make your Arduino project talk with a Raspberry Pi using wire or wireless communication. Better than that, you can reliably send and receive messages to your MCU from the Internet, which can be an AVR or ARM.

Solution Overview
