    We ran a special deal with matrix orbital, sold a cut down version of their 4x20 LCD through a banner on the site - that's a special def file for that display.

    Re: Re: Re: Re: VFD Article


    Sure rob put a link up there, I'd be honoured. I've screwed up even more though, I should have positioned the display higher as I've just gone out today and bought 8 sub-micro push button momentary switches (very sweet) but as the glass is so tight fitting in the 5 1/4 bezel, positioning it in the middle, as I did, just doesn't leave enough space for the switches below, which is where they would be best placed. It looks like I'll be mounting them at the sides of the display at the moment, not perfect but I have no choice. I'll also pop down to the shop tomorrow and see if they'll sell me a spare bezel (everyone has their price)...

    I have a super sweet plan for the buttons they will look so sleek when they are done ~3 days. I'll post another article when completed.

    Have a read of the manual - using buttons with the inputs isn't hard, but it needs better software then LCDC :)

    I'm guessing DJ is working on this :D

    I dont' want to give too much away, this is a competative game, but as you know the display can recieve input from 8 buttons and/or drive 8 outputs. the switches you needd are like PB-126 in this PDF

    Switches

    The tricky thing is how to design a button to go on top that looks cool, you'll have to wait for that one. The potential is a very pro looking VFD mod.....

    From Auckland but I did live in ChristChurch for a few years in the 90's :)



    Ok had another look at install guide PDF and I've done everything like it says to.

    The startup Bit-tech logo and address appear fine
    The System and CPU temps display fine
    The Intel Processor Screen doesn't show CPU MHz but I think thats something to do with MM5
    The Ram stats displays fine
    Voltages Display Fine
    Mail displays Fine
    Clock Displays fine
    Network/Sys Temps displays fine

    But the News and Weather are still wonky, the news when it changes to the next example scrolls accross the whole srceen just for an instant though

    And the weather well thats still all overlayed on itself.

    Do the last two have something in common that I'm not setting up right?

    Most frustrating

    :sigh:

    Is this your first installation of LCDC?

    Have you made any other changes outside the PDF?

    Do the transistions work OK?

    Very weird. Got me stumped. If you import some of the other news screens from the first post do they work?

    I had the same kind of overlaying problems when I forgot to add the corresponding event files for a screen I had just added.

    Mounting

    Oh btw I have a much better way of mounting the VFD than Carpet tape if I do say so myself :lol:



    I don't have a digital camera so you'll have to try visualise this but what I have done is got a busted CD-Rom drive and removed all the inards until all I have is the metal housing.

    Now my case is a Lian-Li PC 61 so I will be mounting it like others have posted in a 5" drive slot but I wanted a way to easily get at it and change the filters etc so the metal CD-Rom case looks like this (top down views)
    Code:
    |------|
    |      |
    |      |
    |______|
    
    Now what I did was cut away the front of the box and then part of the bottom and extended the edges to wrap around the VFD like so; (zoomed in so I can get the detail in ASCII hehe)

    Code:
    
    VFD bolts on here
         VV
    
      _     _
     |       |
    -         -
    |---------|
    |         |
    |         |
    |_________|
    
    
    The VFD is bolted to the metal as indicated above and then the whole unit can be sliped into a 5" slot and screwed in like it was a CD Rom drive. The pieces of metal zig zag like
    Code:
      _
     |
    -
    
    So that the original face plate can still attach to the front Bezel and be removed just as if there was no drive in the Bay

    Code:
    ___________
    |         |            <--- Lian-Li Face plate
    
    
      _     _
     |       |
    -         -
    |---------|
    |         |          <----- Modifed Drive Tray
    |         |
    |_________|
    
    
    This also has the added benieft of giving a enclosure to contain the extra Serial cable and any circuits/mods I want to wire up to the I/O lines

    Works very well, but was a real mission to measure so that the bends were right and that the Faceplate could still be removed and installed.

    The Filters can be taped to the inside of the Faceplate and come away with it when removed so can be easily changed. I'll try source a Digital Camera and some webhosting so this becomes a tad more clear


    (You have no idea how many times I had to edit this to get that ASCII to display spaces as I wanted them /shudder)

    Any idea where I could find examples ? Am I correct in thinking that if you use 4 gpo's as input's That you then have 2^4 - 1 (aka 15, the minus one for the no connection whatsoever possibility) keys ?

    So key 1 -4 = just the pins connected to the ground (0,1,2,3)
    keys 5 - 10 = two pins connected to the ground (0&1, 0&2, 0&3, 1&2, 1&3, 2&3)
    keys 11 - 14 = three pins connected to the ground (0&1&2, 0&1&3, 0&2&3,1&2&3)
    key 15 = all 4 pins connected to the ground

    Or am I way off the mark ? :worried:

    You have the right idea... you can't just hard wire those though - because the switch connecting 1,2 and 0 would permanent connect 1 and 2, so you'd need a double pole switch there :)

    15 actually, because 0000 connects nothing, ergo no action :)

    connect to ground : in the manual, because a switch connect at least 2 poles, so always ground (also in the cases with more than 1 pin)
