How To Build an Arduino Wireless Network with Multiple NRF24L01 Modules

In this tutorial we will learn how to build an Arduino wireless network, composed of multiple NR24L01 transceiver modules. You can watch the following video or read the written tutorial below. OverviewAs an example I made a network of 5 nodes and each of them can communicate with any node in the network and at the same time they can work as both transmitters and receivers. This example is actually set up in a way that explains how to make a much larger network, or to be precise, we can have a total of 3125 modules communicating to each other on a single RF channel. So let’s take a look how it works. In my previous tutorials we have already learned how to make a wireless communication between two Arduino boards using the NRF24L01 modules and the RF24 library. Now in addition to this library, we will use the RF24Network library, which enables in an easy way to build a wireless network with many Arduino boards communicating to each other. Here’s how the network topology works.A single NRF2…

DIY Desktop Light Sculpture

My latest project, the Desktop Light Sculpture, is a digitally fabricated object featuring a 3D-printed base and laser-etched acrylic inserts. Inside the base you can find a neopixel matrix, a Qduino Mini, and a few other basic electronic components for usability.The idea for this project is dependent on edge-lighting the acrylic. What this means is that when light is applied to the edge of a piece of acrylic, it will be picked up by any etched parts on the surface of the plastic as well as along its edges. This creates a beautiful visual effect! The major element of this project is definitely the digital fabrication. I really love that there are two parts to design that have very different design constraints. The first, the 3D-printed base, needs to be designed to fit the electronic parts, hold the acrylic, and separate the light from each row of LEDs (as to not affect a neighboring piece of acrylic). The parameters offer a good design engineering challenge, but offer less in the way …

Maximise system performance with Microchip’s dual-mode power monitoring IC

Single IC offers industry-leading accuracy for real-time power measurement of AC and DC power supplies31 July 2018, New Delhi,[NASDAQ: MCHP] — In systems that use both AC and DC power, the implementation of dual-mode power monitoring traditionally requires multiple ICs to ensure superior performance and accuracy. Growing applications such as solar inverters, smart lighting and cloud servers often use both modes to maintain safe operation, with AC as the main power source and DC as backup or vice versa. To optimise performance and ease development of these systems, Microchip Technology Inc. has released a flexible dual-mode power monitoring IC that measures both AC and DC modes with industry-leading accuracy of 0.1 percent error across a wide 4000:1 range. Power calculations and event monitoring are included with a single IC, reducing bill of materials cost and firmware development time.

Small Low-On-Resistance MOSFET relays from Omron

Manchester, UK – 31 July 2018 – Thanks to the new S-VSON technology, the G3VM series from Omron, available from Rutronik UK, is characterized by a very small form factor. It is suitable in particular for high current and low on-resistance.The G3VM41QR is designed for a load voltage of up to 100 V and a continuous load current of 0.65 A. A high dielectric strength of 500 V/min between input and output and an ambient temperature range of -40 °C to 110 °C complete the high-end features.
The MOSFET relay is therefore ideally suited for semiconductor test devices, test and measurement devices, communication devices, data loggers and security applications such as camera surveillance or smoke detection systems.
More information on the G3VM series from Omron can be found on the e-commerce platform post Small Low-On-Resistance MOSFET relays from Omron appeared first on Electronics Maker.
