Re: Nothing In Particular

Saga STILL HAVEN'T AGREED TO THE REPAIR of my LandRover even though the other party admitted fault immediately (over 6 weeks ago). After many weeks of hassle, I raised a complaint and was called last Monday and was assured it'd be approved by Tues, or Wednesday at the latest. Tuesday: Nothing Wednes...

Re: Nothing In Particular

So what's your view of the running costs and capability of your system Nick ? I've looked into them and decided to hang fire.. hence the 2nd wood burner. It's difficult to compare systems... Our heat pump was installed as part of the complete "green" self-build and conversion we did in 20...

Re: Nothing In Particular

Running a 3-phase vs single phase heat pump only gives a few more percent in efficiency but it all counts. It wouldn't be cost effective to put in 3-phase especially for the heat pump, but we had it on site already as these originally were farm buildings. Sizing your generator to the necessary load ...

Re: Nothing In Particular

3phase motors are more efficient than single phase ones.

Re: Nothing In Particular

I have a couple of chain saws and a heavy log splitter Steve. Don't have a log splitter (rely on the brother in law for that) but do have the chainsaw and wood burner... One plus for doing what I did for the National Trust is that we get free wood from the estate - they have barns full of the stuff...

Re: Nothing In Particular

Having an alternative power source, isn’t the way forward.. “ I’m alright Jack” (no pun intended) isnt fixing the problem of our total reliance on electric going forward, whilst being greener. How can a storm wipe out power supplies, assume its from substation to the end user. Aren’t all new suppli...

Re: Nothing In Particular

Just think of the scenario if this rare weather situation occurs in 10 years when everyone has heat pumps and electric cars.... I wonder what the issues are with the HV grid - is it lack of maintenance, ensuring trees cannot hazard cables etc, as the pylons and cables are designed to cope with real...

They pipe speakers are called Pluto’s- https://www.linkwitzlab.com/Pluto/intro.htm I know that these are celestial names (Pluto, Orion etc.), but I can't help but notice that PLUTO was a top secret pipeline delivering fuel under the English Channel to the beach heads after D-Day...

Re: Millett LR + TP Opus + AMB α24 reboot

Can't see any 100n caps decoupling each chip's Vcc/Vdd - well, there are no chips as such, but decoupling pins 1 & 2 of J1 would be a good plan. Crowbar (diode) between pins 1 & 2 of J1 as well, plus possible tiny power LEDs for both usb & iso sides. No need for decoupling Nick, that'll...

Re: Owston meet 27+28 Nov 21-add your name here

Nick - can you go back and edit in the details into Mike's photo post as and when they become available - it'd be really useful! Pretty please? FWIW, though it'd been great to do a 9+ hour round trip to see what was happening in Owston, seeing the first grandchild for the first time was awesome... (...

Re: Pre-Owston Natter 26th Nov

And when it gets really cold, you can turn it on. Nah, that's when all the output transistors blow up. :shock: :lol: I used to have a humongous Perreaux 2150B 400W class A amp in my workshop that used to idle at about 60C. If it wasn't for the desk space and enormous electricity bills, it'd still b...
