Open architectures for processors too? It looks like it can be done, and probably in the near future. The project of an “open hardware” CPU, entertained only in the academic work until now, is now ripe for commercial purposes. At FOSDEM in Brussels (international conference on open-source projects), which took place in February…
Given two batteries, it chooses the one to connect to the load based on the voltage measured at their poles. It can also be used to switch DC power supplies. The growing demand for portable devices capable of working where there is no power grid or it is not convenient to use it is…
An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
Make use of an ad hoc module by AMS in order to make a precious Arduino based tool. It will allow analysis of materials, including food and drink, through the spectrum obtained with a light stimulus and a sensor, and shown on the serial monitor. Spectrometry is an analysis technique that enables the identification…
Let’s get familiar with a programming language optimizing how we can write code for our Fishino boards, hosted on the board itself. Programming 32-bit Fishino boards can be an easy and light task by using specific tools and platforms; we have found it out in part one of the stories (published in this year’s…
We introduce a programming language to optimize code for our Fishino boards. Part one. What do squirrels and our appreciated little fishes have in common? Very little apparently, but actually, as you will see by reading this article, they have a lot in common, because the combination of the two “critters” can lead to…
Let’s optimize power consumption for our Arduino-like boards using specific hardware solutions and a dedicated software library. We recently had many requests about solutions to reduce power consumption for our Fishino boards, particularly from those – among the designers – who need to activate them for short periods of time: for instance, in…
Let’s learn all the aspects of the most renowned web hosting service, and familiarise with it, thanks to a sample application. In the previous post, we let you know Git and in particular, we focused on explaining how to use it in order to archive a firmware project on your PC and to…
Let’s learn about the firmware management and versioning tool that is at the root of GitHub, and to be able to use it. In order to become a good programmer, it is not enough to know the most popular programming languages, to know how to write the corresponding code, to create more or less…
The latest robot from Waveshare, it adds interesting features to the qualities of its predecessor. You were able to appreciate the instructional robotics platform on wheels called Alphabot, in an article dedicated to it, and you were able to see it in its version with Arduino controller. Alphabot, we remind you, is a robot…
A multirole board, that stands out for its very low energy consumption and the possibility to be remotely programmed, emerges in the rich landscape of the IoT modules. When talking about IoT, we usually refer to devices that are powered by batteries and that are scattered in the environment, for the purpose of acquiring and…
Created for the most famous social network, it displays in real-time the number of likes received by the related Facebook profile, through a giant 5-digit display. Since social networks were born, and Facebook in the first place, it became commonplace to express approval for a comment, a photo or a content in general (which…
