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…
The Zero Multi-Power Supply is a powerful power supplier board for your electronics project and it offers a number of input and outputs and can easily be attached to a breadboard providing outputs from 1.25V-24V. Features are: Multi Input Multi Output Leave Input at the bottom board to support the board and balance the board Wide…
When the instantaneous power consumption exceeds the set values, it selectively disconnects the users, in order to prevent the electric meter to cut the power to disconnect. The management of the electricity users at home, intended as the possibility to define the operating priorities and to momentarily disconnect the ones that may be…
It enables a selective disconnection of a maximum of 7 users, once the maximum power set is exceeded, and by selecting the priorities, so to disconnect the less important ones first. Supervising the electricity, intended as both the monitoring and the management and even as a possible limitation and optimisation, is a topical issue…
If you would like to add a solar panel to your favourite backpack or bag you may be interested in a new tutorial published to the Adafruit website detailing how you can boost the power from a small solar panel to directly charge your smartphone store the energy in a lithium ion battery for use…
A robotics development platform based on a two-wheel mechanics plus pivoting wheel on which you can prototype applications, controllable with popular Arduino Uno, Raspberry Pi 3 boards or both. Robotics is one of the most engaging parts of electronics because it can combine different fields of knowledge and skills in the same project; in…
In the first installment, you had the opportunity of learning about our energy meter, and of learning about its details, with special attention the technical ones. Our energy meter is based on the coupling – by means of two measuring transformers – to an integrated circuit, that enables the detection of the values as…
Thanks to an innovative module, it analyses the electrical grid parameters and the consumption, by supplying them – via USB – to a computer, on which a dedicated software enables to display, collect and use the data for different applications. First installment. It is common to worry about how much electrical energy is consumed,…
PiGlass for sure is a remarkably cool and educational project you can tackle yourself. It’s based around a $10 Raspberry Pi Zero W, and to that you need to add the Pi Zero Spy Cam as well as a Bluetooth dongle, a battery pack, and a few other extras, including the specs themselves. You’re also…
The maker Justin Strawn has just unveiled his new creation: a Raspberry Pi travel companion which takes the form of a small device that offers a portable SD Card File Copier, Phone Battery, Computer and Internet of Things driver. The system is still a work in progress but Justin has published more details and files…
“These days, people tend to jump straight to rapid prototyping with a 3D printer. But, the reality is that it’s only rapid relative to traditional manufacturing. Even a simple design can take an experienced CAD operator hours to model, and then at least another few hours to print on a consumer 3D printer. In his…
Let’s get practical with some examples of combinations of sensors working at different voltages and references for the A/D converter of Arduino. Third and final part. After getting to know and having studied in details the ADC contained in the ATmega328P microcontroller which is equipped with Arduino Uno board’s and more, and after having…
