    Default Burn baby Burn with fake fire

    Hello to smarter then me friends
    If you ever look at new electric fireplaces the flame affect on most is like someone spray painting red on a cardboard box
    in other words looks great from the moon. I decided (two years ago) I am going to make a "real" looking flame so I tried everything my
    simple mind would process like with amber leds and having pieces from tinfoil to wet toilet paper flash against it all of them looked like garbage
    I then tried instead of having the leds reflect off something.. put the leds sideways in a flame like pattern of course being a behind the garage shed mechanic
    this was no easy task but I did manage to make a interesting flame which looks almost ok

    here is video https://www.youtube.com/watch?v=RyGE-ogcikE

    I will try to update this post after I test my next idea
    the flame in the video uses 28 micro leds from ebay cost 10 dollars wait time from china = forever I think I used canoe shipping
    1 picaxe 20m2 (best chip for plumbers)
    4 -74hc595 drivers (all driven from westaust55 code)
    1 real lighter (if your dissatisfied of the flame then use lighter for backup)
    My main goal is to make a fireplace so real you dont want to touch it with leds and picaxe
    your friend
    who tries and tries

    The 'flame' looks quite realistic, although it may be more suited to a flare at an oil refinery! Thanks for sharing.

    Now duplicate that 512 times and you have a fireplace!

    You put in a lot of work, and it shows.

    Looks good for an accent or gas ignition effect. I can't tell if there is some randomness to the shape.

    Here's one that's pretty good: https://www.youtube.com/watch?v=jTdq9-pUacA

    It uses water vapour and 4x50W coloured incandescent bulbs. It's a lot less spectacular than yours though!

    yes thanks the video doesn't show clear because of the brightness I tried using bright light /no light to get it to be clearer but no better results
    PhilHornby I know I seen them but who wants to pour water everytime they want fire. For reals the reason why my flame flares up is because
    I just can not get speed to flash it fast enough but I am going to try using my 40X2 with 20mhz clock then I can hopefully make it wave or etc
    I love texasclodhoppers thought lol " ONLY 512!"
    I might just buy one of those northwest led fireplaces off ebay for 250 rip it apart see if they have anything better but guessing they dont
    because my personal thoughts they look like red paint on card board again plus I think its just the crystals they use for the flame with leds under neath
    I am very picky that the flame must look very very real and I wont stop till they quit making leds.

    @ newplumber,
    Have you seen the fan driven bits of fine cloth(I'm not into dressmaking) illuminated by red and orange LED bulbs.

    @the bear yes and thanks for the input tho
    I bought a few of them awhile ago and did everything I could to make it flash better with bad results but they look okay in the fog
    one thing that keeps me motivated is a fireplace has 3 sides to hide everything
    I'll update this thread if I accidentally discover some real flame
    your friend who tests things but forgets the results

    Make a fake cast iron fire with a rpi and tv or picture frame player and play something like this. It's a project of mine on hold. https://www.youtube.com/watch?v=0fYL_qiDYf0&t=22s

    Dimplex have that sort of thing too: http://www.dimplex.co.uk/products/fi...i-v_effect.htm I dread to think how much they are!

    I've seen cheaper versions, that just have the LCD screen (no glowing LED logs, or 'crackling' audio) - they're fooling no-one

    (OK - I admit it, I'm a Dimplex fan-boy )

    Little up date
    After working with just single leds now I am going to try working with
    these
    http://www.ebay.com/itm/COB-LED-Fila...58jVGmwgvB7pEQ
    it doesn't say how many leds per filament but i guess 12 + ... to bad they dont make these filaments in apa102s (micro size)
    I also wish I could control each led by amount of voltage applied but after watching videos such as this one
    https://www.youtube.com/watch?v=25j2C4jq2HI
    ..all leds are attached in series so all I would be able to control I think
    is dim to bright but i will add more when i get them to test
    If anyone has did tests to these kind of led filaments it would be great to hear
    thanks
    Mark
