Hi folks,

I'm looking for ideas... I need a big, highly visible, low power, seven segment display. Actually, two of them.

I want something at least three or four inches high, and it needs to be visible in direct sunlight or against a bright sky. LED *might* work but I'm not fully convinced - I'm thinking of those electromagnetic twisting shutter types but I have not yet found a supplier. Probably I don't know what to look for... any thoughts for such things in the UK?

Ta,

Neil

Wimbledon surplus auction? Those scoreboards are magnificent. :D

You need something that can turn/swivel 90 degrees (e.g. the innards of a cheap voltmeter). Everything black, except for the brightly painted segments (fluorescent paint or plastic).

If you think education is expensive, try ignorance.

But twice the size I need.

I think the gasoline-stations have also
nice displays.

I already found that one, emuler, thanks.

Ossi, those are the animals. I have a nasty suspicion, from the absence of prices on *any* of the sites I've found with them, that they may have too many digits on the end.

Another - and almost certainly cheaper option - may be to rig a stepper motor with a big pointer on it... all I need to do is show approximate wind speeds. Big segments at 0-5, 5-10, 10-15, 15-20, 20-25mph and over with a resolution of 1 mph would do the job.

(roughly translated as downhill only, possible, just right, oooer, flying backwards, and you bloody lunatic).

For flappers, there's a company across the channel called bodet that makes these.

How about a bar graph. Might be more robust; needles tend to get bent. You could have a bi-colour display to show the position of the active element.

I found Bodet; they have no stock, no prices, just 'get quote'. Not promising...

The more I think about this, the more enticing high-brightness LEDs are looking. :o

It's because you're British - just don't mention the war! They're too busy munching on onions and a baguette methinks. You only need a 150mS 12V pulse to change a segment.

Someone in another thread recently mentioned http://www.distel.co.uk -- it looks like http://www.distel.co.uk/asps/details1.asp?ID=RW46 may do what you want.

Exactly the animal and at a sane price... I'll give them a call though; Display Electronic's (dire!) front page is nine years out of date... Thanks!

Maybe this animal is insanely expensive and small since it is trully SMD...

PS: SMD stands for Super Mini Display ;)

Look what I got!

Twenty quid each. The digits are a shade over six inches high (150mm or so).

(I worked out if I got another twenty-five, I could build an enormous sudoku display for the office wall... shame it would cost another five hundred quid (plus vat!))

Beautiful. :D A touch of fluorescent paint and a couple of spotlights, and this will be great in the dark too.
