When the widget you’re working on is powered by a battery or a USB charger, running it on the bench is probably pretty safe. But when the object of your …read more Continue reading Tricking a Smart Meter into Working on the Bench
There are a lot of good reasons to have a better understanding of one’s household power use, and that is especially true for those that do their own solar power …read more Continue reading Live Energy Monitor Helps Plan Power-Hungry Appliance Use
Just to intensify the feeling of impending zombie apocalypse of the COVID-19 lockdown in the British countryside where I live, we had a power cut. It’s not an uncommon occurrence here at the end of a long rural power distribution network, and being prepared for a power outage is something …read more
Sentenced to a year in prison for disabling networks, he changed a password to “f***you.” Continue reading Some beers, anger at former employer, and root access add up to a year in prison
Termineter is a Python Smart Meter Security Testing framework which allows authorised individuals to test Smart Meters for vulnerabilities such as energy consumption fraud, network hijacking, and more. Many of these vulnerabilities have been highlighte… Continue reading Termineter – Smart Meter Security Testing Framework
[Aleksejs Mirnijs] needed a tool to accurately measure the power consumption of his Raspberry Pi and Arduino projects, which is an important parameter for dimensioning adequate power supplies and battery packs. Since most SBC projects require a USB hub anyway, he designed a smart, WiFi-enabled 4-port USB hub that is also a power meter – his entry for this year’s Hackaday Prize.
[Aleksejs’s] design is based on the FE1.1s 4-port USB 2.0 hub controller, with two additional ports for charging. Each port features an LT6106 current sensor and a power MOSFET to individually switch devices on and off as required. …read more
The Internet of Things has been applied to toasters, refrigerators, Christmas lights, Barbies, and socks. Unsurprisingly, the Internet of Things has yet to happen – that would require a useful application of putting the Internet in random devices. One of the best ideas is a smart electric meter, but the idea behind this is to give the power company information on how much electricity you’re using, not give you an idea of how much power you’re pulling down. The answer to this is the Internet-enabled Kill-A-Watt, and that’s exactly what [Solenoid] is building for his entry into the Hackaday Prize. …read more
