Engineering suppliers in UK

[Viewmaster]

For those in UK building the mechanics of NBTV, or anything else, here's a big list of engineering suppliers, many with web site links.

I've used Reeves, EKP, Kerjeng, JA Crew ( a bit slow in posting).RDG and many others without any hassle.

Those wishing to reproduce Dussaud's Telescope can find suitable(?) selenium cells at http://www.megatron.co.uk/selenium/index.html (price list linked on the bottom of that page).

This chap has a long list of links to engineering and electronics items and those I have dealt with have been very good.

His note regarding how to order at the end is very true.

An individual company I personally recommend is

If you're after obsolete or near-end-of-life bits they'll probably have it. e.g. Gernainium diodes.

I find Maplin a very poor shop now compared with what is was 10-20 years ago....and that bloody music thundering out in their shops is a big turn off for me.
ESR of Tyne and Wear is good as is Cricklewood electronics....you can pay by cheque....I never use credit cards over the net as someone once used mine to bet on! Never again.

Agreed Albert, remember those big fat Maplin catalogues printed on cheap paper you could get in WHSmith for a quid fifty?

When I was last back in the UK in 2006 I decided to take a stoll up Edgware Road and just browse all the electronics shops, not to buy anything unless I saw something that caught my eye.....

...they've all gone! I'm not including PCs, phones or consumer stereos and the like. It was a real blow. So I retreated to the pub next to the Edgware Road tube station.

A sign of the times I guess, most are too lazy to build things themselves, all they want is instant gratification.

Back just after the war there were many electronic surplus shops in London, Lisle St being the centre.
If you go back that far you may like to read my write up on Lisle St and its History and many other such shops on part of my web site here.......

Steve, this piccy will bring back some old memories then. I bought this when the price was £1.25

You gotta admit the covers were pretty naff, even in those days.

re Engineeering Supplies, welding goggles.

I wonder what the response time is for the automatic darkening welding goggles, and what mechanism is employed. Liquid crystal?

Might be of use as a light valve for NBTV perhaps?

This one is .08 millisecs......

Some are faster. 1/25,000 sec

0.08 secs, it has possibilities.

Has anyone used such a filter in NBTV?

(Mind you the large visor and helmet might look strange!)

Re-reading that info I see its 0.08mS, not secs. Now that is fast...

The price is high as well.

There is such thing as 'smart glass' (that's glass with the gl ! )
Used for windows. Controlled by switching on or off electrically. Not sure how fast it is though.
A small sheet of this just behind the Nipkow might offer some research, rather like a Kerr cell.

Yes, I've heard of smart glass but I'd always understood that it had a fairly slow response like photochromic lenses in spectacles.

Still another avenue to explore,

I wish we could all find a 'smart' hour glass to give us the time to explore some of these avenues. Maybe it could convert 24 hours into 1,500 minutes or more.
