This is actually being tried, starting this month, in my area ( https://www.bbc.co.uk/news/uk-wales-56293250 ) Monthly council tax will double for properties that do not have occupants. This is due to my area having over

When you're docked in a marina or similar its unlikely there would be space. When you're sailing or motoring somewhere you want the minimum drag\resistance through the water, and more importantly, the waves would smash them to pi

I'd heard of this as a theory many times before, I didn't know someone had actually built one! Good site too, thanks for the link.

This is a good summary and I agree with the vast majority of it, with the exception of >"Beware of “wet sand”. These areas can seem bottomless and usually require assistance" sentence. I'm no expert but I do drive on UK b

If you need to control mains AC loads, I highly recommend something like the Sonoff Wifi switches. They're similar to the wifi "Smart plugs" you can get these days but are aimed at fixed wiring installations and they're

I parsed that on first read as "no (arms or legs)" instead of "(no arms) || (no legs)" and was very surprised!

I live near Dinorwig pumped storage hydro and can highly recommend the tours they do if you're in the area. The tour bus drives into the mountain and stops literally a few metres from the generating turbines where you can get out and t

As a slightly related precedent, some early trucks used an engine->generator->wires->electric motor system as an electric transmission as this worked better than the early gearboxes. On a bicycle, the wiring would certainly be easy

Thanks for sharing that, I notice they have an overlay for ocean temperature as well, so you can visualise both the heat flows and absolute temperatures on the same map: https://earth.nullschool.net/#current/ocean/

I can highly recommend the "Wemos D1 Mini" for starting with ESP8266 as it's tiny, cheap but can be plugged in to a PC to be programmed over USB and has pin headers and readily available shields for getting started quickly. I

Really nice to hear that. After having Pi's for years, I've just picked up 2 fitpc2's, one I've made into a small headless DVR for my single IP camera (running Shinobi\Node) The other I was hoping to put Kodi on to sit b

I'm surprised this isn't higher on HN given the tech nature of the attack. Gatwick is one of the busiest airports in the UK and having flights suspended for 24 hours is major disruption. A few quotes from the BBC's live incid

Very cool but really, really needs a volume control so that I can set the radio volume separately to the other tabs I have open.

Stainless steel cable is used in the fixed rigging (mast stays) of yachts precisely because of it's anti-rusting properties. Unfortunately the stainless still has to be completely replaced every 5-10 years because it weakens to the poi

We tried this with our fleet of landrovers. Each one has a waterproof interior and is plumbed with sprinkler pipe with hoze-lock connectors on the back of the vehicle so it can be plugged in to the water supply. It doesn't work, the wa
