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 spend a chunk of time o

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 techniqu

Huh, impressive - I guess I'm out of date (and/or the people I listen to about such things have a working XRF already and don't want to replace a working unit).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 from a homogeneo

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 whole new

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 FP4 that was avai

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: [ https://rsgb

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 rust!

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 burnables may still be

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 below freez

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 air h

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 future (amusing

"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 out

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've s

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 change th

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 when it exhausts

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 doors throughou

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 brick-built ter

Hey, accident twins! I once had a Zippo lighter that was playing up - you could strike it and you could see the spark fly, but it didn't light. I sniffed the wick, yeah, definitely fuel evaporating off it. I struck the striker, yup,

To answer your question, the lifting technique I refer to works well on flat paper and variably well on non-flat paper. Something as delicate as a letterlock, I'd be seriously concerned about my hot knife nicking or tearing a part of

It's pretty easy to non-destructively lift a wax seal off of paper, with a sharp, hot knife and a bit of practice. You can then read the letter and reseal it with a touch more hot wax or the back of a heated spoon (to melt the back of
