Early days at Watford Electronics

Popular UK hobby magazines like Practical Electronics, Everyday Electronics and Practical Wireless featured a wealth of constructional projects for electronics hobbyists to tackle. For most of us, getting components meant sending away for them by mail order. One supplier was Watford Electronics Ltd. of Cardiff Road, Watford, a supplier that I myself used in the 1970’s and 1980’s, as I’ve described elsewhere*. So I was delighted to hear from a former staff member at Watford Electronics, Ian Nicholls, who wrote to me with his interesting story describing life behind the scenes in the earliest days of Watford Electronics. I’ve précised it in this feature, for electronics enthusiasts who, like me, used to mail in to Watford Electronics in an era when home computing was also gaining popularity.

If you use aerosol air dusters regularly then you'll know some of the problems they cause, including freezing and condensation, never mind the high cost. An electric air duster offers many advantages over pricey aerosols and can pay for itself over time, as I explain in this article.

Samsung TV PIP (Picture in Picture) grayed out?

How to enable Samsung TV PIP If you have a Samsung TV - even if it’s a few years old - the chances are that it offers Picture in Picture (PIP) so you can view two channels at once. I’d never managed to get it working, not that I’ve tried much until now...

Has your Google Home Hub locked up?

It seems that scores if not hundreds of users of Google's First Generation Home Hub LCDs are now staring at blank screens through no fault of their own. No-one's got any answers and there's no sign of any support either.

A Google system or firmware update late last year is being blamed for bricking these Home Hubs (now called Nest Hubs) leaving owners in the lurch and needing to buy a new one - or ditch the thing altogether. Read more...

Windows 10 Right-click not working

If you’ve a laptop or notepad Windows PC, you might sometimes find that the right-click of your touchpad feature isn’t working properly (if at all). This can be very frustrating when working in Windows Explorer or using any Windows shortcuts: the context-sensitive menu doesn’t appear when you right-click.

There’s a lot of the usual garbage around when you Google for a solution to “right click not working in Windows 10”.  Some sites that offer the ‘solution’ shamelessly try to flog you some software (‘free download’) instead. Many such utilities can do as much harm as good, sometimes frightening you into thinking that you've got an unrelated problem with your PC that their paid-for software will cure.

One web site comically suggested using Task Manager (ctrl +  alt + del > Task Manager) and right-click the Windows Explorer app to stop or restart it: but how can you, if right-click isn’t working in the first place?

The answer could be very simple – before splashing out on software that might be useless anyway, try this: on your desktop go Start > Settings > Devices and choose Touchpad.

Scroll down till you find the option Press the bottom right corner of the touchpad to right-click

This option may be hidden at first, no thanks to the scrollbar being hidden by default over on the right edge. In my case, this option was ticked but I’d forgotten! This feature overrides the traditional Windows right-click option, and so that was the answer: just tap the touchpad on the bottom-right to make a right-click. You can of course disable this option altogether to restore the traditional way of working.

Windows 10 thin scroll bar annoyance

The scrollbar width mentioned above is another annoyance, and a feature too clever by far. Only by hitting the wafer-thin ‘scrollbar’ does a full width one pop into view, one that you can actually operate with a touchpad. It is borderline inaccessible and very frustrating for many users.

To override this feature and make scrollbars ‘normal’ again, just go to Settings > Ease of Access > Display, and scroll down (somehow!) to find Disable the option ‘Automatically hide scrollbars in Windows’. There you can restore scrollbars to the normally accepted behaviour and the problem will be gone for ever.

Adding the Google AdSense ads.txt file to the root (Squarespace 5)

Seems many people are struggling with this or think it's not possible to upload a Google AdSense ads.txt into the root, but in Squarespace 5 I figured out a simple workaround using a 301 Redirect instead. All I can say is that after 4 days Google spidered my site and the pop-up warnings disappeared. More details here.

Brennenstuhl Mains extension leads with (ta-da!) both left-hand and right-hand cable exits

One of life’s annoyances is that the mains lead (power cord) of many trailing power cord extensions often sprouts from the ‘wrong end’ of the plastic housing. Then the extension must be used ‘upside down’ or the mains lead has to be ‘doubled back’ to reach the wall outlet. This post highlights some really neat ideas for mains extensions from Brennenstuhl, including pop-up hidden power sockets and trailing leads that have double-ended cable exits.
