Sodium sulphate
Sodium carbonate
Sodium percarbonate(I'm not a chemist but) sodium hydroxide isn't listed and I presume it would be as it's hazardous?

so is grinding finer, reducing dose, increasing contact time by grinding finer for the same dose or reducing pump pressure.
Hmm, thanks. I've always found this quite a difficult process. The pump pressure is fixed as well as temperature so I'm only working with dose and grind. And I feel like I'm generally skirting between clogging the machine and producing some over-extracted sludge, or something sour. At the middle point between the two with a 30s extraction it also seems to be sour.
Will have to experiment with a dark roast and see what happens

I feel like I struggle with sourness on 90% of my shots. But it's really hard to compare without a second machine. I'm generally using 3rd wave fancy stuff in a range of roasts, but nothing that is like Italian-style dark which is maybe what I should be using.
I need to go to some cafes that do a definitely good espresso I guess to compare
Edit: mostly I'm doing milk drinks though which means I'm not too bothered about a suboptimal espresso

I've always struggled with my shots on my Bambino Plus, just read this:
Lots of beginner home baristas are picking up the Bambino Plus because of the great features vs the low cost, and it really is a stonking machine for the dosh, but there's a recurring theme among bambino plus users, and that is sour shots.
This is just an issue with lighter roasted beans.
If you're using a more traditional darker roasted espresso blend with the Bambino Plus, its factory pre-set brew temp (which you can't change) should be about right, and you should be able to pull some great shots for enjoying neat or as the base for milkies, or Americano.
If you're using lighter roasted beans, though, you're probably going to need to up the brew temperature to pull out more of the sweetness, and the inability to do this with the Bambino Plus is likely to lead to sour shots.
My personal opinion is that if you're planning on using lighter roasted coffee beans rather than the more traditional darker roasted espresso blends, the Bambino Plus probably isn't the best machine for you.
Is that correct, that 93°C is too low temp. for a light roast?

Thanks for this by the way, I had seen that one but it was out of stock everywhere.
I like handlebar mounting because it gives you the option of using a front roll when bikepacking and it's easy to remove. I found a couple of other options, coincidentally both on Wiggle:
Exposure "e-bike handlebar bracket" - okay but doesn't give you much adjustability due to the triangular shape of the mount

Lezyne e-bike centre forward mount - also okay but not super robust.

B&M alu is probably the most likely to survive a bashing I suppose.

While stacking has uses for decreasing noise it will not increase resolution.
You definitely can as long as the PSF is bigger than one pixel. You can't decrease noise and resolution at the same time (well you can, but you're trading one off against the other). You obviously can't do better than the diffraction limit

Anyone have one of these? Would half of it be sufficient for a light or do you need both halves?
I want a handlebar light mount - currently I've got this one which is perfect aside from the fact you have to unwrap the bars if you want to remove it. I don't have dynamo lights on the bike all the time

I think it makes sense that some portion of the private school fees is reinvested in education for the general public (ie. 20% VAT). The current ruleset is that the school says "we're a charity so we can't take a profit and have to reinvest in education" and in practice that means buying a tennis court for the fee-paying students. That's not really investing in education in a charitable sense, you're just providing a service to rich people
If you bring in a tax on private school fees, make them retain charitable status, and ringfence the money for education, you get the correct outcome which is that any money spent on school fees benefits the students at the school as well as all children in state education (to a lesser extent)
Edit: if extra "profit" is spent funding bursaries that is a similar outcome, but this way the state is mandating that 20% of the fee goes towards state education, whereas bursaries are at the school's discretion, so the school gets to make the decision between a new swimming pool or taking a couple of inner city poor kids. You're setting a minimum level of charitable public good.
Tea bag straight in the caddy: accelerates the mingingness of the compostable bag and contents
Tea bag in the sink: doesn't dry out because of people using the tap
Tea bag on the dish on the side: looks disgusting
There isn't really a good solution. I squeeze it out in the sink and then put it in the compost
If you squeeze the teabag into your tea you might as well just reuse an old teabag out of the compost, since you clearly lack taste buds
