35mm slide viewers

A 35mm slide viewer to avoid!

I’ve a collection of 35mm slides, many of sentimental value – in my view there’s no substitute for viewing original and evocative pictures on the actual film that captured a scene for posterity, like playing back a treasured tape recording of some original sound tracks hailing from bygone years.

To preserve images for the future it’s easy enough to scan them onto disk or upload to the cloud, but I think that simply flicking through a slideshow of JPEGs on a screen isn’t the same as seeing ‘the real thing’. I used my legacy Microtek Scanmaker 8700 to scan twelve 35mm slides at a time onto hard disk, but how best to view the slides themselves periodically, though?

The obvious answer is to use a battery-powered slide viewer, so for starters I tried a Hama slide viewer model DB 54. It’s a compact 2 x AA powered thing containing a filament light bulb and plastic lens, and I have to say it proved to be a complete waste of money. Here’s why: the plastic lens was of such poor optical quality that it distorted the image like crazy; I had never seen such a bad example of pin-cushioning and the centre of the image suffered from a mini-magnifier type effect. It was hopeless. Secondly, the small torch bulb produced a mediocre, dimly lit, yellowing image that detracted even more from the quality of the image.  No, the Hama DB 54 was not for me and mine’s headed for the recycling bin.

Then I remembered that, actually, I had in fact bought one of these some years ago and thought the same of it then. I’d sent it back. Catch me once, shame on you – catch me twice, shame on me!

Scouring the web for alternatives I found a neat LED 35mm slide viewer branded as PhotoLux SV-2.  Desirable features include a real glass lens and x2 magnification and it uses daylight-temperature white LEDS for a light source. It’s 2 x AA powered – and it proved infinitely better than the Hama.

To demonstrate the problem of distortion I made a 35mm transparency slide based on a simple grid and photographed the results, which speak for themselves.

You can buy the Photolux SV-2 from Amazon. For more intensive use the Photolux SV-3 handles negative strips as well as slides, has a push-button slide collection tray and is x3 magnification, needing 4 x AA but it has a mains adaptor socket as well.


World Business List directory scams

Here’s the latest in a long line of useless Business Directory listings that I've reported on in recent years. They mostly originate in Holland – this latest one purporting to be from ‘World Business List’. Apparently, updates are (still) free!

I’ve had a few requests asking for advice on replacing the OLED displays in a PURE Avanti Flow. I managed to fix a used, working Avanti Flow which needed a new display but the Avanti Flow is much trickier to repair than an Evoke Flow as it contains a sandwich deck of printed circuit boards inside, each connected by a spaghetti of ribbon cables all located in a restricted space. A full tear-down with photos is here.

What’s happened to Westfalia.Net?

Wo ist es? This online emporium run by Westfalia Werkzeugcompany GmbH was a goldmine of mostly German quality, hard to find tools, equipment and materials for the homeowner, DIY enthusiast, farmer and hobbyist. Not to be confused with Westfalia towbars, this Westfalia worktools company (“Qualität aus Hagen”) boasted 95+ years of service and had a UK mail order outlet at Seems Westfalia have abandoned the UK market and retrenched to Germany.

Everyday Practical Electronics changes hands

Hobbyist electronics magazine Everyday Practical Electronics (EPE) has new owners. It's been taken over by Matt Pulzer, the current Editor who acquired the title from Mike Kenward and Wimborne Publishing Ltd. on 2nd November 2018. The title will now be published by Matt's new company, Electron Publishing Limited.

New title and magazine style coming in March 2019All the core features in the magazine will stay the same but readers can expect a 'refresh' and restyle and this has already started with some column artwork redesigns. The most important news is that, as from April 2019 issue (published in March), the title will revert to its original one of Practical Electronics.  The 'Everyday' moniker (inherited from Everyday Electronics, a beginner's magazine) was past its sell-by date and no longer needed, so the original Everyday Electronics title will finally be laid to rest.

Stewart Kearn of Wimborne Publishing is helping with the transition over coming months, so it is hoped to be 'business as normal'. Further changes are in the air including the website and shopping cart, the latter never really having been polished off since it was introduced a couple of years ago.

Change is in the air, with the UK's last remaining hobby electronics magazine looking to appeal to the rising trends in the maker and coding sectors. Constructional projects will still be sourced from Australia's Silicon Chip magazine and there are no plans to move away from them. One benefit is that by the time they appear in EPE, the projects have been fully sorted and sometimes updated, so EPE readers benefit from SC's  learning curve.

Interesting and exciting times are ahead, so watch this space for more news.

If you own an old PURE Evoke Flow DAB/ Internet radio then it's likely the yellow OLED display will have failed by now. They have been impossible to find until now - at last I found a source of replacement displays so this article with step-by-step photos describes how to repair the OLED display of a PURE Evoke Flow.

Jul072017 lights out?

It has somehow slipped beneath the radar but the website of - the IT vendor that rose from the ashes of the old Watford Electronics - has disappeared altogether. Nowhere can I find any details about their downfall though.

The website is unreachable and at the time of writing, their domain name has been suspended at Nominet too. The dot-com domain merely shows a private registration now.

Clearly a wheel has fallen off but it's very sad to see this particular brand name sink without trace. I used Watford Electronics some 40 years ago to supply parts for my Multi Channel gas Sensor and other magazine projects, when they ran a small shop on Cardiff Road, Watford.

The original Watford Electronics shop, 33/35 Cardiff Road.I believe that originally Watford Electronics was set up by Nazir Jessa and his son Shiraz ran it. The name 'Watford Electronics' is now a dormant company [resulting from changing the name of another associated company to Watford Electronics] controlled by Shiraz Jessa, maybe for sentimental reasons(?).'s address was Jessa House, Finway, Luton founded in the era when the home computer sector was thriving.

Several popular UK PC brand names eventually crashed and burned, including Tiny and Carrera and after diversifying into the IT sector Watford had its fair share of woes.  Today's PC market bears no resemblance to the scene of the 1990s and 2000s. A useful write-up on The Register is here.

I won't rake over the ashes any longer but I wrote a piece about the original Watford Electronics shop, as it now appears on Google Street View, here.

I also scanned my catalogue rear cover (image, left), as a nod to those fun, exciting and pioneering days of 1970s hobby electronics that I grew up with, eagerly awaiting my next packet of parts arriving in the post, paid for out of my pocket money.
