Yeah, the math I did was for heating water by 50 kelvins for a 9 l/min showerhead, which in hindsight was probably overestimating it. It'd make sense if the actual answer for most people was 2-4 seconds
>> 1. Always sad for me to know how much popular are wireless chargers, wasting 47% more energy aprox for charging the same as a wired charger.
Sure, but compared to everything else we use, smartphones use almost no energy. The one I'm typing this on has a battery capacity of 12 wh; if you have a resistive electric water heater, standing in a hot shower during the winter for an extra second would offset half of that.
In the meantime, I'd highly recommend PlatformIO over the Arduino IDE for writing code for embedded- besides having a much nicer UX, (they recommend using their VSCode extension, which is great, but they also have extensions for a dozen other IDEs) it natively supports way more boards and frameworks.
Holy shit, this is some clever marketing.
Kinda wonder if any of their employees were part of the warez scene at some point.
