UK 13 Amp Plug and Mains Extension Lead Safety Issues

Introduction

The initial purpose of this post was to raise awareness of a UK 13 Amp Mains Extension Lead Safety Issue. I came across it by chance when I landed on the PlugSafe site. I’ve taken the liberty of reproducing their information below and enhancing their picture. Full credit to PlugSafe for making us all aware.

As a consequence of a comment on the initial post I have also included an issue with the safety of 13 Amp Mains Plugs too. Continue reading “UK 13 Amp Plug and Mains Extension Lead Safety Issues”

Radio Controlled Wall Clock In My Shed

Introduction

I have for some time wanted a reliable time piece outside my house. I don’t actually require an exact time outside anymore than I do elsewhere, but I do need to get the grass cut by teatime. So, I have acquired a Radio Controlled Wall Clock for my shed.

I have had the difficulty of not being able to see any of the indoor clocks easily through the windows from outside the house. Although I have a wall clock in the kitchen I have to open the door to see it. Reflections on the windows make it difficult to read otherwise.

Condensation Free Bathroom Mirror

Introduction

This post describes how to make a condensation free bathroom mirror using an automatic mirror heater. See the one I made in 2007 here. Look carefully and you will notice the condensation around the edge but not in the central heated area.

Without a heater it would be impossible to use the mirror without first wiping it with a towel. Cold mirrors usually mist over again after wiping.

With an active mirror heater it’s possible to get straight out of a bath or shower and use the mirror immediately.

Using A Digital Signature With Outlook

Introduction

This article covers some of the issues involved when using a Digital Signature. Each Digital Signature is generated from a Digital Certificate (otherwise known as a Digital ID) issued by a certifying authority.

All examples given are created using Microsoft Outlook 2010 on a PC using Microsoft Windows 10, but the principles apply to other versions of Outlook and other email clients.

This article has been written to compliment my previous article Make Safe Financial Transactions.

Anyone using an Apple Mac can get appropriate certificate information in this article published by TechRepublic entitled: How to configure digitally signed email in Apple Mail.

Lighting Charts – Which Lamp Do I Need?

Introduction

We are all trying to reduce energy costs and CO2 emissions by choosing modern alternatives to incandescent lamps. Here are some lighting charts to help you select the best lamp for your situation. Since the decline of incandescent lamps there have been many alternatives made available based on fluorescent tubes bent in many ways to condense a long tube into a confined space.

I had my first Philips SL prismatic Compact Fluorescent Lamp (CFL) lamps soon after they came on the general market back in the 1980’s. I only recently sent my last one to recycling after deciding that even my shed could do better than have one of those long time warm-up devices.

Fluorescent Tubes

In the early days of low energy lighting there was nothing better than the good old fluorescent tube, usually confined to kitchens and garages in the British house. I still had two twin fluorescents in my kitchen until 2015. If you want the room lit without shadows that’s the way to do it. After much searching in 2003 I found some streamlined fluorescents fit for the modern era to replace my old fluorescent ‘chunky boxes’. Unfortunately they went off the market and I struggled to find a decent looking replacement that didn’t cost a fortune. There were some problems with the ones I used. They had a self destruct mechanism built-in. The plastic fixings for holding the wires in place on the frame all deteriorated under the ultraviolet light given out by fluorescent tubes. I replaced them with zip ties but they suffered from the same problem.

Lamp Brightness

To get back to the point of this article, which is to advise on the brightness of replacement lamps, I have chosen to publish a chart by espares lighting chart which seems to relate to the UK/European market and another by ovo-logo which relates to the American market and appears to suggest their lamps emit more light than European lamps, e.g. UK/European 100W ≅ 1300 lumens, American 100W ≅ 1600 lumens (see A USA Lighting Chart).

WordPress Fatal Error Out of Memory

How I Resolved ‘Fatal Error Out of Memory’ For A Single Post

After much editing  of my WordPress post entitled ‘How A Toilet Silent Fill Valve Works’ , since I wrote it in May 2014, (there must have been at least 150 edits, and I changed it from a page to a post too) I suddenly had this ‘Fatal Error Out of Memory’ script on the WordPress White Screen of Death when I tried to edit it:
