Having said that, we’ve not had snow or anything – there is no chance of it being a white Christmas for example. I’ve been buried away in my workshop now for some time, taking advantage of the bad weather to get stuck into some new learning.
On the right you’ll see my new toy – a home-made-from-scratch ultra-sound humidifier. The idea came to me one morning as she was griping about the room being dry. Inside the £2.99 B&M glass-with-wooden-stopper case is a £4.99 high intensity ultrasonic steamer from China, which when fed 24v (supply came with the unit) generates one hell of a lot of cold steam due to silent ultrasound vibration. Then follows an aluminium tube from B&Q, a 25mm processor fan (£1 from China) and a little convertor to take 24v down to around 3v (£ from China). The 5v fan forces air into the container and hence lots of very fine steam out. I dropped the voltage (to the fan) to reduce noise to virtually zero. Right now it is running flawlessly and I’m waiting to see how long it takes and how much water it takes to make an effective change to the room humidity – which, run by radiators and fire – tends to get a little dry at times.
The whole thing is on a Sonoff controller hooked back to my house system which knows how dry or otherwise the room is and controls accordingly. At least that’s the plan. How well it will survive cats sniffing, running dry and other daily challenges remains to be seen. Also needs a protective shield to stop the fan getting damp and make it look more presentable. It did occur to me that a somewhat more powerful version of this would be ideal for the pergola in the height of Spanish summer. We have misters but they provide rather large water droplets whereas this is REALLY fine stuff. Could be nice for compensating for the blisteringly dry heat in August.
Other than that, Maureen is doing her usual Christmas stuff, I’m focussed on my blog which is just about to tip 6,000 signed up visitors and needs lots of attention. Some day if the sun ever gets out we’ll get around to some outdoor activities.
