    Where is the best place to buy large seven segment displays ?

    Some where that keeps them in stock.

    Preferably 4 digit clock display or 2 digit.
    12cm high or larger.

    Also who carries ftdi usb to rs232 in quantity ?


    Thanks
    Alex

    Kingbright have the SA40 and the SA50 series, (100mm and 127mm respectively).
    Tenrod in Sydney are their agents and the datasheets are available on the
    Tenrod website.

    BTW, the SA50 has a comma, as well as the decimal point.
    Tenrod should be able to give you price and availability of the displays.
    Dontronics has some, but do you mean large quantities? (>1000)

    The agents are:
    Ravar ( Gigatechnology ) Australia
    Ravar Pty Ltd

    Southport 4215

    Thanks.
    Appears they have stopped making the SA50's no longer listed on any of the kingbright web pages.
    Hopefully can still get 6 or 12 of them.
    I'll have to give them another ring.
    Whoever it was on the phone yesterday afternoon must have been having a really bad day.

    Wish they would fix their website
    so it works rather than give errors.

    Don's a bit pricey even with his discount for quantities.

    After around 100 at the moment
    Trying to get cheaper than Aus$5.00 a chip
    www.kitrus.com/bits.html appear to be the cheapest so far
    even after adding postage from Hong Kong.
    Hoping to find somewhere that had some in stock and
    I could get them in the next two weeks rather than after christmas.

    Thanks

    Yeah, I get that info as well, even using Netscape 7.1. The website appears
    orientated towards Microsoft's Internet Exploder. Their designer appears to
    be unaware that not all browsers are created equal. I use Smart Explorer when
    I want to view pages geared towards u$oft's IE.

    Getting back to your original query, you could assemble a large display using
    a large number of individual rectangular LEDs, or even LEDs mounted in plastic
    similar to Jaycar's LED bar graph display (ZD-1702). It certainly would be
    cheaper, however it would also give you the option of selecting high brightness
    LEDs.

    I prefer crazy browser for when I have to use ie.
    http://www.crazybrowser.com/
    basically a front end for ie that allows tabbed browsing.

    The tenrod site still gives errors.

    Error Occurred While Processing Request
    Error Diagnostic Information
    An error occurred while evaluating the expression:
    #cboGetCat#

    Error near line 12, column 18.
    Error resolving parameter CBOGETCAT
    ColdFusion was unable to determine the value of the parameter. This problem is very likely due to the fact that either:
    You have misspelled the parameter name, or
    You have not specified a QUERY attribute for a CFOUTPUT, CFMAIL, or CFTABLE tag.
    The error occurred while processing an element with a general identifier of (#cboGetCat#), occupying document position (12:17) to (12:27).
    Thought of using individual leds. Maybe for another display but for this one ,
    avoiding having to do circuit boards.
    Using one of the futurlec control boards and soldering some connectors
    on to the prototype area.


    The matrix led modules would be easier than using individual leds.

    Its for a largish clock display, 6 digit.
    This time I'm just going to go with
    some of the kingbright SA50's or similar.

    Once I've finished this one, may do a board using surface mount leds for
    clock display / message board.


    Found out that for the world cup, Foxtel(one of their contractors) bought the onscreen display game timers
    from overseas because they claimed they couldn't find anyone in Australia capable of making them.

    Thanks

  6. Not sure if best is meaning "cheapest", however Farnell have some 196mm
    high 7 seg modules (#366-5331). They are made by a company called Forge
    Europa
    (www.forge-europa.co.uk)

    They can be clipped together to form a larger unit.

    They are about $100AU



    I am looking at using about 12 of them in a couple of projects so would
    be very interested in a cheaper/similar source.


    Regards
