Just a random thought. We're in a rural location and we saw some odd behaviour when bigger machinery was powered up. Turned out that our power quality wasn't great - nominally we have 100A 3phase but with only a 36A load the utility voltage was dropping from 240 to 210. A long and tedious...

I've seen one before - a dental mouth gag - it's screwed in to open up the jaws of someone who can't or won't open their mouth...

...perhaps that should be "dissecting"? "Explaining a joke is like dissecting a frog. You understand it better but the frog dies in the process." E.B.White

Used to live in St. John's NL back in the '80s. -40 used to happen in winter. C vs F? Doesn't matter. It's the same in both. We'd leave long sticks stuck in the ground next to the cars so we could find them in the morning. Cars had block heaters so you left them plugged in overnight to stop the...

Bit of a dichotomy. I'm a life-long Beekeeper. Wasps are incredibly important to the local ecosystem and if at all possible, should be left well alone. However, wasps can completely destroy a colony of bees in just a few days. In the autumn, wasps can try to invade a beehive to steal stores...

...which is a very good point. You have to start somewhere and a step-by-step tutorial can get you up and running. I admit to being a bit OTT with some of this stuff - frankly, it might be much simpler for the OP to use Arduinos as the ESP stuff, whilst wonderful in the longer term, is probably...

That's fine until you want to do something different or it goes wrong. Plus, and this is one of my pet peeves, a lot of "tutorials" contain errors which reflect a lack of understanding by the authors. I'm picky/borderline obsessive about this sort of stuff as I firmly believe tutorials should...

Blame it on the contractor, not me!! He was told to leave it... It is what it is... Little point in "if only..." Anybody in the Tunbridge Wells/Cranbrook area want a bit, you're welcome...

I used similar modules to monitor my beehives... difficult to just go and look at them when I was living 5,500 km away...

It has an inbuilt USB connector that appears as a COM port within the Eclipse IDE - you can then upload the compiled binary/program the ESP32 directly from the IDE without needing a separate programming dongle. There are other options as an IDE - PlatformIO, Arduino, even Visual Studio Code and...

Occasionally it works well - about two years ago, B&Q (who are the same group as Screwfix) had a silly sale on where I ended up getting a Dremel 4000 kit (about 40 bits, including the flexible extension and a case) for £40 quid., They often do "buy two power tools and the cheaper one is half...

I program mostly in C++ using Eclipse as my IDE and Git as the SCCS.

Well, that's odd as I have about 6 round the house all using WiFi... Supports 802.11 b/g/n Wi-Fi connectivity with speeds up to 150 Mbps.

That's the theoretical case, but not the practical realisation. Rayleigh scattering is not related to and has no effect on the sky temperature. Deep space is around 3K (-270C) but the earth's atmosphere is a great insulator (CO2, water vapour/cloud cover, dust etc.) plus all bodies (including...

Varies: from maybe 3" to 10"+

Regrettably they're only about 18" max - the contractor who was removing the bulk of the tree cut it up before I got there - bit annoying though - we had to use a contractor as it was a specialised felling as the tree had fallen over a road.

Just had to take most of one down and log it... Very dense... Is it good for anything? (Apart from spindles, toothpicks and skewers, that is...)

Ok, let's do some "simple arithmetic". Looking at Energy Cost Comparison (10/2021 figures, other similar tables are available) for example, assuming a new oil boiler running at 90% efficiency (i.e. a perfect installation & commission), that's 6.44p and 0.298 kg CO2 per kWh . The efficiency of an...

Interested in why you say that. What reference source gives that data?

The phrase "Hoist with his own petard" is from Hamlet, so yet another one down to Shakespeare. Interestingly, whilst a "petard" means a small explosive device in several European languages (including English), the etymological roots are from the French "pétard " which translates as "to break...
