Add a ‘Charging’ indicator to the Ryobi One+ 18V USB Adaptor

One handy accessory is the Ryobi 18V USB charger (R18USB-0), which clips onto a One+ battery to provide two 5V USB ports rated at 2.1A and 1A. It’s intended to charge eg smartphones on the go but could also power other USB gadgets, LED camping lights or chargers etc, acting like a souped-up powerbank. It could also prove handy during power cuts. The only control it has is a simple ‘start’ button on top. Once you press it, the charger powers up and automatically shuts off again 8 hours later. For some reason there’s no at-a-glance indication of whether the charger is actually working or whether it's finished. I've now figured out how to add an LED Charging indicator to the USB charger to show that it's operating, an upgrade that turned out to be easier than I expected. Anyone with hobby and basic soldering skills should be able to do the same, following my outline guidance below.

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.

Garland Bros. Ltd. – gone but not forgotten

Updated on Saturday, February 5, 2022 at 11:44PM by Registered CommenterAlan W

Whilst trawling through my archives of Practical Electronics magazines – I was compiling some PDFs of the 1970/ 71 PE Gemini amplifier for a reader – I stumbled across an advert for a supplier named Garland Bros. Ltd. who were located in London. Their black and white ad showed an impressive shop storefront, enhanced by signs overhead sporting a shopping list of many of the electronic components that they sold. 'South-east London's leading component store', their ad. exclaimed.

Basic Soldering Guide by Alan Winstanley.pdf.exe – Torrent Malware warning

It’s come to my attention that a pirated copy containing malware is starting to circulate in the Torrent network. As always, this is fuelled by people’s greed, fools trying to download something for nothing and coming unstuck in the process.

A phony copy of my book has been disguised as a PDF but it's actually a small executable (.exe or program) file called The Basic Soldering Guide - Alan Winstanley.pdf.exe. I have nothing to do with this file. It points to an illegal, pirated version of my original ebook, presumably hacked from Kindle. The .exe tacked onto the end should immediately cause alarm bells to ring. When you try to fetch this file for ‘free’ from Torrent websites, it tries to drop a suspiciously small .exe onto your system that will then install Malware, tricking you into thinking that it’s installing a pirated PDF.

Torrent malware tries to drop this small "PDF" as an executable program file [click to see]It should not be run under any circumstances or it will install harmful malware onto your system that may prove very difficult to get rid of, or could cause permanent damage.

Downloads folder (IE11) shows filename and signatory [click to see]A programmer named as Yuriy Drachev has been associated with this malware. That name also popped up when I analysed the .exe – see screenshot above. It is possible the name is false or spoofed but see FreeFixer which identified the same issue at  http://www.freefixer.com/b/yuriy-drachev-virustotal-detects-the-download-as-multiplug/

and Herd Protect  http://www.herdprotect.com/.pdf.exe-6a2826f148db59af2f210c66facf85642fbe5b0a.aspx

The good news is that Kindle sales of my 'BSG' are higher than ever. The only way to get a clean, malware-free copy of the Basic Soldering Guide by Alan Winstanley is via your local Amazon site. A hardcopy paperback is also on sale, and a spiral-wirewound layflat version for education and benchwork is sold on Magcloud.

Don’t be fooled by innocent-looking files fetched from the dark web. Some downloads and file attachments could even destroy your system completely – such as the deadly Rombertik virus that arrives in a small screensaver (.scr) file but will try to smash your hard disk MBR and render your PC useless.  See Cisco’s log at http://blogs.cisco.com/security/talos/rombertik if you don't believe this.

Interview Part 6: a labour of love

In Part 6 of my potted history (nearly there now!), we pick up the story as we entered the early 1990s. The hobby electronics market was still quite buoyant at this time and Everyday Electronics and Electronics Monthly (to give it its full title then) was going from strength to strength. I tackled the flagship tutorial series, Teach-In '93 featuring the Mini Lab and Micro Labs.  Read more...

Readers' prototypes

Following the intermittent appearance of my ‘potted history’, regular reader and friend of EPE Thomas Stratford got in touch to say that he’d recently built a couple of my legacy electronic projects! Thomas’s projects include the Uniboards Touch Switch and more recently, the Continuity Test Unit. If you've tried any of my projects, it would be great to hear from you.
