I'm waiting for some Android tablets. I expect many items to go missing in transit, as striking workers make a point.

It uses a big main battery and a CR2032 - is the main battery user replaceable and is it expensive? I'd hope it's user replaceable. 20 hours will become 16 etc. with time and use.

I'd deffo buy a spare battery while they're still making them, otherwise you might be desperately going at the casing with a Dremel in a couple of year's time attempting a repair.

That'd keep this 40W electric blanket which is presently making me sweat, working for 6.4 hours at the garden. I'm completely inside the "Mummy style" sleeping bag which contains it now, and it's forming a hood keeping my head warm too. Now that I have turned my central heating off completely, I'm going to see how long this remains bearable to use. But so far, so good. Mostly.


When I lived in a ruin, a few years ago, I built a room within the ruin 10ft square and 7ft high with a foot of cheap rockwool insulation on all faces. With good draughtproofing too it only needed me and my laptop to keep it warm.
Did you say that your solar trailer generated 1000W a day? Which panels did you use and how much would a home setup cost, for placing against the windows? Would such situated panels even generate 1000W a day with the same number of panels? This electric blanket needs 960W a day to run continuously, so may be able to provide personal heating for free? (After initial purchase of solar gear and battery of course, but I suppose I could start by using my existing ebike battery).

(Wh, not W...)... Sadly, not in the winter. Mounted vertically or very steeply I.e. perpendicular to the sun, in a proper blue sky condition you can expect a similar yield of about 3Wh per W of labelled peak power, but in overcast that goes down to close to zero. So the average is woeful unless your proportion of sunny days is quite high.

But that needn't matter in this case, because you are after heat, and south facing vertical glass I.e. windows are excellent at capturing 'solar gain' during winter months in our northerly latitudes.

A well insulated space, which could be a single room within a house, or an insulated shed, with a decent sized south facing window will be amply heated during sunny daylight hours. Including within the insulated space 'thermal mass' will soak up daytime solar gain and keep you warm during the dark hours. The window needs to be high spec double glazing, and curtained during darkness for best effect.

This is the sad thing about UK housing: this is basic physics and sensible design, does not have to be expensive, but for best results has to be done at the design and build stage.

RM are bloody useless. I bought something off Ebay, when it arrived it was the wrong Item.

I returned it to the seller (Signed for) and he sent the correct item plus my return postage. He never got the returned package and the RM tracker showed it was still at the drop off point.

They assured me it had been picked up and gave me a claim form, filled in and sent off with original proof of postage as required. They lost that as well and then refused to process any subseguent claim because I no longer had the original receipts etc (Because they had lost them). Screen shots were not good enough.

I was also told that they no longer request a signature due to Covid (This was only a few months ago). So paying for a "signed for" service is simply fraud as far as I'm concerned.

It's little wonder RM is is dying a death, I for one am no longer prepared to send anything other than a letter using their service.

Absolutely shocking! :eek: I was dreading the prospect of the new Android tablets I've ordered getting lost due to issues caused by the strikes, but if all that happened to you BEFORE the strikes, I'm even more nervous than I was before. A usual 4 day delivery could take weeks, or weeks to resolve.

Did they say that they could have helped you, if you had sent the receipts by recorded delivery? Depending on the item's value, I would have chased the Royal Mail through Small Claims Court.

Thank you for that information - I now compelled to ask how long it would take to charge my 19.2Ah battery at 2A or 4A, using this 100W pedal generator? I hear pedalling is a good exercise, which might also keep me warm - pedalling with effort would be a novelty for me: thanks Bafang firmware!

My windows are useless for trapping heat, even with black curtains and double glazed panels, in any direction.

A bit late for that I'm afraid. I noticed I have cavity wall insulation, while drilling through the walls to install an alarm system. When unheated, my home is never as cold indoors as outside. But it's not 31.9 degrees Centigrade, anywhere outside my sleeping bag at least.

via evri.
In my experience, Hermes (now Evri) used to be the absolute worst... but now if the package is too large for the letterbox, the couriers have to prove the exchange has taken place, by taking a photo showing the delivery address's open doorway and the recipient.
