Saving the world

I'm having a lot of fun in isolation, and one of the more unusual things I have been doing is that I bought a goat. You see, I've been helping a charity I support with their website to fix a few niggles, clean up the presentation, and improve search engine optimisation, as well as set... Continue Reading →


I'm on day 10 of 84. Just short of 12% of the way through. Nearly 1/8th of the way through. Which sounds better? 50% sounds good for when I reach day 42 – I'll celebrate by visiting the other end of the caravan. I'm coping quite well, I think. I've always been a bit of a... Continue Reading →


Last Monday I was advised by the NHS that I am a high-risk patient and I should self-isolate for 12 weeks. This was confirmed by my cancer team – no surprises there. Thankfully I have neighbours who are food shopping for me. Notice from the NHS about self-isolation. I was supposed to return to the... Continue Reading →

Sad story

Sadly, Okonomiyaki, my my lovely and ancient (>17 years old) cat probably had her back broken by a vehicle in the campsite today. Thankfully the vet was open despite the lockdown announced on Saturday and only 5 minutes walk away. After a very short examination it was decided that she should be put down because...

All Around My Hat in Russia

Watching a sci-fi series on Netflix, Better Than Us, and as it's a Russian production I was surprised to hear one of the characters humming the melody to All Around My Hat. 🤨 It starts here:

Voltage reading problems

Having the laptop connected to the ESP board via USB while it is charging pulls the voltage reading down, thus switching the relay off at high voltages. This means suboptimal charging opportunities while I experiment with the solar management system. A solution is to do away with the USB connection by utilising the WiFi capabilities...

Boiling a kettle for 10 hours

The controller keeps a record of how much power has been generated. I installed a solar power system while in the UK but I didn't bother connecting up the solar panel until I got to Spain where our local star actually makes an appearance. This is the system: The charge controller and breakers. The bare... Continue Reading →

The relay has finally arrived

The SSR-40 DD Solid State Relay So I've put the relay in place of the LED and connected it to the 12V supply for the peripheries and discovered a problem. Putting the ESP module into deep sleep switches the relay off – which is what you'd expect if you think about it. So, here's the original... Continue Reading →


It's not always like this. I went to Coín last Thursday to meet Manolo. I was a bit bored so I fancied a drive and what a drive it was! Coín is a smallish town nestled in a group of mountains about 200m above sea level. As I approached the brow of the last mountain... Continue Reading →

Exploring code techniques

The relay should arrive by Monday, fingers crossed. It will go where the green LED is. In the meantime I continually have to keep an eye on the solar system, during which time I while away the hours reading, feeding the cat, browsing the web, and, my project for today, exploring ways of writing code...

Some code

I am designing a system to optimise solar charging opportunities for: laptopphonebackup battery for phoneAA rechargeableshandvac This is facilitated with a NodeMCU micro-controller ESP8266 (ESP-12E module): This is so I don't have to keep an eye on the system during the day to prevent the leisure battery from being damaged. I am waiting for a... Continue Reading →
