Re: Antibacterials and Other Household Products Nasties

But then the bag would become fouled! *yes

The bag could of course be changed but any water trapped inside it could support growth.

Re: Focus stacking in landscape photography

Joe Cornish uses (or used) this technique with his large format (5x4") field cameras.

The lens is fitted to a bellows, and may be tilted independently of the camera body. This not only provides...

Re: Antibacterials and Other Household Products Nasties

I wish it were that simple. *yes

People have tried all sorts of biocides in antifouling paints, but most are costly and all have their drawbacks.

The present trend is towards so called...

Re: Antibacterials and Other Household Products Nasties

Tributyltin definitely did have an effect on marine organisms, which is why it was banned!

There was strong evidence that tributyltin was affecting the sexuality of dog whelks, but action was...

Re: Vintage Kit

Yes indeed. They had a mechanical multivibrator which drive a step-up transformer as a crude inverter generating the 200 volts or so needed for the valves' anodes.

Later designs used germanium...

Re: Antibacterials and Other Household Products Nasties

Zinc pyrithione, which is the active anti-dandruff ingredient used in Head & Shoulders shampoo works extremely well as an antifouling co-biocide on boats' bottoms.

There were concerns that the...

Re: The Future of Cars

Yes indeed, but of course wages were very much lower then, so perhaps the politicians thought it was better pay men (and it was mainly men) for doing something worthwhile rather than claiming...

Re: The Future of Cars

Thinking back to the 1960's and 1970's these 'promises' may well have been well meant. Gas and electricity were still state owned and it really didn't matter whether they made a profit or not. From...

Re: Vintage Kit

I don't know about the current JLR models but the clock in my 2015 XF does not update itself, and there is no option for it to do so. JLR's explanation is that many of their vehicles regularly travel...

Re: Vintage Kit

I had the same problem at about the same age.

When I started work I spent most of my first month's pay on a second-hand Philips GA212 Electronic which I still have, and which still works...

Garrard's 'Transcription' decks such as the 301 and 401 were of very high quality, and were standard equipment in BBC studios and suchlike, but their consumer decks such as the SP25 were crap.

Re: Vintage Kit

Most car clocks now should be synchronised with RDS data, but as our daughter has found, this only works if you tune in to main BBC radio stations once in a while. ;)

Re: Vintage Kit

Interesting question. Most of the big names in high-end audio such as Mission, Quad, Wharfedale, Audiolab and Castle Acoustics were bought up and in many cases rescued by the Chinese owned IAG. Most...

Re: The Future of Cars

That is true. Nothing like the whiff of Benzine for clearing the lungs.

Re: Geared Steam Locomotives

There is no EXIF data but opinion seems to be that it was late 1950's. As you know the line was permanently closed in 1962, pre-Beeching.
