Thank you! I don’t think it’s faulty (but it might be a design flaw) because I have four of them with two different lamp shade designs bought at different times and they all exhibit the problem to some extent. I did wonder if something is odd about my wall (ceiling) voltage actually. But it’s...

Can you tell me why you chose those values (470nF + 100r)? I will order the one you suggested from RS, which comes in a through-hole package. They also sell https://uk.rs-online.com/web/p/rc-network-capacitors/6167682 which is 100nF + 100r and comes with flexible leads which would be easier to...

This is interesting. I actually have the components to make this, but I’d likely want to buy one to have it be tested / safer. I am confused about fitting between switched live and neutral though. Wouldn’t this in essence create a short when it’s such low resistance?

Hi, I have just is installed several Philips ceiling fans with LED lights – three Atlas models and one Bliss – in different bedrooms. These models are basically the same fan and light source, they just have different aesthetics. Significantly, the Bliss design lets more light out of the frosted...

Only one, in the downstairs hallway. Also note that - in the airing cupboard at least - there is no motorised valve on this mystery pipe. There is underfloor heating in all the bathrooms with their own thermostats but I have always assumed they are electric. Each bathroom has a small display...

There are actually four. Better picture here: The hot water comes in from the floor into the red pump. On the left it goes down through a motorised valve into the floor. This i assume is for radiators. Further to the left it bends around through another motorised valve and into the primary...

This explanation is brilliant. Thank you! That makes sense. And means I can just keep it as it is. For what it’s worth, Tado also has hot water control. I don’t think this is worth the cost but interesting to consider. Could you help me understand where it is and how this works, out of...

Hi, I’m trying to get my head around the plumbing in a new house. I intend to install a Tado smart thermostat system, but unlike my previous home, this one has two programming units and I am confused about how they interact and what one of them actually is for. The first part of my question is...

As far as I can tell there is a gap both in front of and behind the metal frame. So if I poke something into it, it falls out the other side. Maybe I can manage to bed some wire around the back so it doesn’t. Worth trying.

Correct. The threaded holes for the handle bolts are stripped.

there is clearance either side of the metal bracket that the bolts need to attach to. And this is encased in the uPVC itself. So it’s not obvious how to add something here

It has one bolt either side of a handle that turns in 90 degree increments. The actual mechanism is operated with a square spindle. So I guess “new style”? The two nothing bolts go through a hole in the uPVC and into a metal bracket which is inside the window itself. I suspect the bracket is...

Hi, On one of our uPVC windows, the handle has been pulled out by years of kids opening and closing the window and the handle being loose. Unfortunately it’s not just a matter of tightening the bolts, because the bolt holes in the metal bracket inside the window are stripped. The screws won’t...

That’s good advice. I have plenty of polarity reversing adapter leads . :)

I must admit I did not spend much money on the power supply itself. I’ve actually tested four different AC-DC power supplies for the 90V AC potential to ground. One is a £10 9V power adapter, plastic middle prong. Then there are a 12V and an 18V plastic-middle-prong adapters that are the input...
