Foundation licensee here in the UK, working on my Intermediate (and hoping to pass that exam this year). I manage the radio system for the UK Discworld Convention (every other year, next instance August 2026), and I…
Simplified English is a thing that exists, for clarity - see for example https://simple.wikipedia.org/wiki/Practice I don't know if the parent comment was trying to equate American English and Simple English - I can see…
XRF will go a millimetre or so into the sample AFAIK - it's mainly useful for finding alloy contamination, e.g. "this is 99.99% gold" vs "this is 73% gold and 27% other things" - you really want to use both techniques.…
Huh, impressive - I guess I'm out of date (and/or the people I listen to about such things have a working XRF already and don't want to replace a working unit).
On the individual scale, something like a Sigma Metalytics resistivity analyser (passes an electric field through the sample, checks to see if resistivity, conductivity, weight or size all match up to what you'd expect…
I don't think it's a dumb question, though I guess some might question its relevance. Side-comments can be interesting, though. I don't know why they did it, but it follows the same pattern as the pi400 - develop a…
Three "bad" missiles over a five minute period. The hit on the WCK convoy killed the latest 7 out of over 200 aid workers who have been killed in Gaza since this latest war began.
Do you have a copy of the hardware manual for the thing? If so, I believe the Connections Museum would love to borrow it :)
Yeah, same here: I upgraded to an FP4 about three months ago (from an increasingly-broken-down Samsung Galaxy S9), after puzzling for a while over whether I should wait for what looked like an imminent FP5 or just grab…
The thing is, there ARE chunks of spectrum dedicated to digital comms within the amateur radio bands. Here's a link to the VHF band plan we use here in the UK - obviously I can't speak for other countries:…
TBH, I don't have a problem with Rust so much as I have/had a problem with a section of the rust community. The shouting fanbeings of rust put me off looking into it for years, because when I kept getting "rewrite it in…
No, but I see what you mean. Generating hydrogen and methane using electricity will probably never be that efficient, but if you have spare power then using it to get 60% of its energy back again in the form of future…
Yeah, I'd like to see those figures too, and I think they might surprise you (and me). I don't have figures or references to hand here, but as I understand it modern heat pumps should be good down at least a little way…
In the context of heat pumps, a "backup heating strip" is a resistive heating element - electricity goes in, heat comes out just like an old electric heater. They're generally used during defrost cycles for the external…
I always forget the size difference between US and UK homes (I assume toomuchtodo is speaking from a US perspective). Here, in my three-bedroom UK house I'm on a 60A service fuse and considering updating to 100A in the…
"Affordances" are a UI design concept - they're things that the design of an object makes you think you can do with that object, if that makes sense. In this context, door handles afford being pulled (because they stick…
It is indeed a concern, and I suspect that's why they're recommending any wikihous project include a full-house MVHR system (see About=>Product, the bent arrow near the middle of the image map). MVHR is the solution…
I really want to see more electric conversion kits for existing cars, I must admit. It seems like such a waste to throw away what is in many cases a perfectly good chassis/geartrain/body/etc just because you want to…
They're not so much unreliable as ... really not very sensitive, as I understand it. Viral load in covid sufferers follows a curve with a rapid ramp up and a slower ramp down, both PCR and lateral-flow devices require a…
Most air-tight houses have an integrated MVHR (mechanical ventilation with heat recovery) system, which is kind of the inverse of an HVAC setup. There's a constant small air current being moved through the house, and…
pv == photovoltaics - rooftop solar panels, in this case.
Correct, the British Royal Air Force.
Looks like that trial's currently not accepting new participants, but thanks for the link - I'll keep an eye on it in case that changes. The retrofit plan that an eco-retrofit architect is currently drawing up for me…
The whole bill of work is as follows: * Full external-wall-insulation (180mm thick) with brick slip dressing so it doesn't stick out like a sore thumb amidst all the brick houses in the road. * Triple-glazed windows and…
Possibly-relatedly, I'm in the process of getting some retrofit work done on my house to improve its insulation and reduce the carbon costs of heating it. I absolutely had not appreciated that a place like this, an 80s…
