In theory at least, with the right PID settings you should be able to stabilise the process because the PWM control will just send shorter pulses to the large element. I have created temperature and humidity control systems for everything from swimming pools to hotel function rooms and...

A lot of these devices use a technique called pulse width modulation to turn the element on and off many times per second. Depending on the error (i.e. the distance from setpoint), the pulses will vary in length. As the error reduces then pulses get shorter. In this way the rapid, variable...

A unit is a kilowatt-hour (kWh). So a 1000 watt (1 kW) load running continuously for 1 hour consumes one unit. A 2000 watt (2 kW) load running continuously for half an hour also consumes 1 unit. A 2000 watt (2 kW) load running continuously for 1 hour consumes 2 units etc.

A great outfit for sure. I was lucky enough to hear the writer of this song, John Hiatt, perform it in Pistoia, Italy back in 2012. As for Sara Watkins, I've been a little bit in love with her for years due to her work with her brother Sean and mandolin player Chris Thile in their band Nickel...

Kin. A gritty Dublin gangland feud... 1st series on iplayer.

This is where your worlds collide @Chippy_Tea : :laugh8:

The SS Chronical 7 Gal is about twice the height of a 25L plastic bucket.

Starting the weekend with one of my favourite beers.

Enjoying a nice pint of London Pride whilst waiting for the gig to start… Just 4 hours to go. 😂

In that London for a concert tomorrow night so we’ve headed out for a curry…

And measured to perfection. If you put another coat of paint on that ceiling you'll need a shorter airlock! 😂

On the other side of the coin wind generation is making a major contribution at the moment. 😂 National Grid

Indeed. Cornwall is right in the eye as you say: Global Wind Map. All quiet here in Northern Ireland at the moment too.

Weather Report - 8:30 Not everyone's cup of tea I grant you, but I played this album non-stop on the old Pioneer cassette player in my beige mark II Ford Escort back in 1982 and I'm feeling nostalic this evening. 😊 Jaco Pastorius... man. This album and Steely Dan/Greatest Hits was all I...

New guitar arrived today. A lovely Gibson CS-336 (on the right) which asthetically looks very much like my Gibson ES-339 (on the left). They are cousins for sure but in terms of construction completely different beasts...

A final Aruba Ariba whilst we wait on a taxi to the airport…

Last day of our 40th anniversary trip to beautiful Aruba. Just waiting for another local brew to be served from Balashi Brewery, which is very popular here. It's quite a nice spot to have a beer too. 34°C at the moment...

We managed to find a little brew pub. They only have one beer on tap at the moment as they are having issues getting hops from the USA. It is a NEIPA. Quite a mango or maybe passion fruit flavour. Excellent mouth feel. A smooth drinkable beer. I will have a few of these…

A popular local beer. Barley malt, wheat malt and hops according to the detail on the bottle. Most refreshing.

We made it. 😎
