Felix of LowPowerLab posted an update on his DoorBell Mote project: My first DoorBell Mote prototype was working nicely and it allowed monitoring the door bell (while also triggering it remotely – toddlers love it). But I wanted more. On weekends the family likes to get a well deserved nap during the day and often […]
Energy Wristband monitors energy usage on home
https://www.electronics-lab.com/energy-wristband-monitors-energy-usage-on-home/
by Matt Venn: A wristband that tells you energy changes in your home. It connects via a Raspberry Pi computer to a base station like a ‘current cost’ or similar. When a change in energy usage occurs, the wristband vibrates and a small LED bargraph shows your current usage from 1 to 4. Energy Wristband monitors […]

2 New Families from Microchip
https://www.electronics-lab.com/2-new-families-from-microchip/
by elektormagazine.com: Microchip has introduced two new 8-bit MCU families with integrated Core Independent Peripherals (CIPs). You may be thinking that 8-bit processors are unlikely to cut the mustard for many of today’s applications but built-in interconnected CIPs combine to perform functions autonomously, without intervention from the processor. This makes these new 8-bit families suitable […]
