Re: Arrows

Method: Rather than visualise this with arrows, I drew lines. One advantage is that a line can be in either direction so I could determine this later. It was just a case of drawing lines between dots on a 4 x 4 grid. Since there are seven 7-spot arrows, seven of the eight possible lines of length 3 ...

Re: Arrows

Why would this challenge be impossible if the set consisted of one 1-spot, seven 2-spot and eight 3-spot arrows? Spoiler to second part: Consider that the chess board would have black and white squares. Arrows with one spot or three spots would point to a different colour square. In order to finish...

Re: Car battery ID

Hi Julian, You seem to have had bad luck with your batteries at about 1 year. Cheap batteries and a lot of cranking probably did it. The lower CCA battery should have been enough though. The better battery required less cranking and lasted many years. I have come to be suspicious of multimeters as ...

Re: Car battery ID

I had a K-reg Diesel Astra once which didn't start as easily as it should have done. When I replaced the battery with a calcium one of the heavier duty recommendation, the car started much more easily. I don't remember what the difference in CCA was, maybe 20 to 30% of the old one, but the starter m...

Re: Large scale UK power cuts

Simple AC motors would run slow, which means fans cooling them would run slow, hence they could burn out. Three-phase induction motors are often run as variable speed drives via inverters. The required voltage is proportional to speed, and the speed is primarily determined by the frequency. An inve...

Re: Large scale UK power cuts

I suspect the power cuts were partly the EU's fault... Nah, forget the EU! Things have been going downhill ever since they repealed the Corn Laws. :) I think that that is a very good point. We never had power cuts in the mid-1800s. It is only after the corn laws were repealed that we have had these...

Re: Pressure Sprayer container leak

Filler rods are new to me and I cannot immediately identify a source. I wonder if a strip cut from a scrap LDPE container could be used? I see that the melting temperature of LDPE is 120-180 deg C. I have soldering irons and a hot air gun - an iron is liable to be too hot and the gun not localised ...

Re: Large scale UK power cuts

Generating capacity is lower than it used to be, so power shortages are more likely. Electric cars anyone? There are a lot of new houses being built around my way and elsewhere that will need electricity. When is gas being phased out for domestic cooking and heating? That said, would it not be sens...

Re: Can't connect to the internet

Anyway, will try resetting the router first and take it from there. The router is what connects to the outside world. Home plugs or wifi are just the internal network in your house.

Re: Pressure Sprayer container leak

The letters "PE" appear on the base which suggests either polythene or polyethylene (high or low density not apparent) Polythene, polyethene and polyethylene are differrent names for the same thing. I would expect PE to be low density polythene, although it is sometimes abbreviated to LDP...

Not as crazy as it sounds. :lol: I know a plumber who did that with a copper central heating pipe after he holed it with a nail. (In his own CH system, not a customer's.)

There should be a symbol somewhere on the container (probably on the bottom) to say what it is made of, https://www.pstt-cpd.org.uk/ext/cpd/primary-qr-site/plastic-recycling-symbols/ The container will be made of a thermoplastic which cannot easily be glued.

Re: Which cloud, if any?

I use three hard drives in rotation. I can fit more than one backup on each. I also use blu-ray disks for additional backup. These are easy to store off-site.

I have never used cloud storage for backups. What happens to the data if it rains? :)
