Silicon Labs announced a new family of secure, ultra-low-power Zigbee system-on-chip (SoC) devices designed for eco-friendly IoT products deployed in mesh networks. The EFR32MG22 (MG22) family delivers the smallest, lowest power SoCs optimized for Zigbee Green Power applications. Based on Silicon Labs' Wireless Gecko Series 2 platform, the MG22 SoCs are an ideal choice for Zigbee devices powered by coin cell batteries or energy-harvesting sources. Target applications include smart home sensors, ...
(or singles awareness day)   Everyone has a love in their life, their partner, pet, a television show, and for others it is their favourite electronics project that takes pride of place in their application or showcase.   Though for most of us, we do not always love our electronics, in fact, they can be the bane of our existence. Whether it's the work virtual private networking not functioning, computer memory deciding to fail, or our mobile phone not having signal.   For me re ...
I'm starting to get more experience with my laser and I'm trying to do some photo engraving on craft wood.  It's taking a lot of iterations to figure out the correct settings for transit speed and power for different materials and my workroom is starting to smell like a fireplace !   I had planned to do some active ventilation and/or air filtering when I started using the laser to cut wood as that generates a lot of smoke but I'm discovering that engraving is also problematic even ...
Whether you are a fan of them or not, flexible touchscreens will be a major part of future technology in both the public and private sectors, and researchers at RMIT University have discovered a new material that could forever change how they are made. This new process is so unique that it could drastically reduce production times as well as production cost, paving the way for cheap, ultra-thin and flexible touchscreens in every home!   The ultra-thin and ultra-flexible electronic materia ...
Introduction   More experimenting. This time I thought I'd have a look at the output characteristics of a JFET. Sometimes these things go well and sometimes they don't. This one didn't go too well but, for all that, I'm going to blog it as I did it rather than try and tidy it up.   The output characteristic is how the drain current behaves with changing drain voltage and is usually shown for a series of fixed gate voltages. Here is an example from a datasheet. This is for a 2SK355 ...
