    Re: Analog VU Meters

    Dean,

    Two questions . . .

    1) would it be possible to replace this image in the SB firmware as a local
    mod? Since it's a bitmap the size shouldn't vary. I can probably work out
    how to do the binary patch, but I'm not sure how to get the firmware update
    into the SB. Also I'm worried that if I get it wrong I won't be able to get
    back to the working version.

    2) the images show measured values from -20db to +3db so the firmware is
    selecting the image based on something like:

    image index = 32 * (dbLevel+20)/23

    As I said before is it possible to get dblevels > 0db? if not could this be
    changed to

    image index = 32 * (dbLevel+20)/20

    The bitmap would have ot change in a corresponding fashion, but it would buy
    a few more steps of detail.

    I've just taken a look at the binary and the bitmap seems to be built in in
    some compressed format - it certainly isn't quoted verbatim, so I'll need
    help to edit it

    I love this - I think the best approach would be to have a 3-4 stick men
    across the display and have them dancing. At -20db they would just be foot
    tapping, at 0db they could be going bananas, then you can have your own
    stick man rave in time to the music

    Hi All,

    Here's a different visualisation so the guys at slim can play (and I hop it will encourage them to make tools available so we can design our own vu meters).

    Anyway the attached file is a stickman rave party visualisation - to make it work it has to be dropped into the firmware and only slim can do this

    Dean,

    I couldn't open the attachment. Both XP and WinZip 10 reported it to be corrupted or invalid. Could you send it to me?
    jon[at]theheals[dot]org. Thanks.

    Great job mwphoto!!

    I bet this looks absolutely hilarious. Dean can you give it a try and tell us what you think?

    Just think the party on the SB would really have twice as many people as in a single frame because of the two channels. Awesome!

    This all makes me more eager to see the visualization interface opened up in some manner as discussed in this thread: http://forums.slimdevices.com/showthread.php?t=19171

    Dean,

    Before I expend too much effort, I want to make sure that I supply you something that -- assume you like it --you can actually use. I have not yet taken a look at your file as I cannot open it, but I'm assuming that you need 32 images of the meter. I was planning on creating the images in grayscale -- black with two shades of gray on a white background (for the fourth bit, which I assume, is "off").

    I'll start out with 32-bit images, and Photoshop actually does a pretty piss-poor job of dithering down to 4 bits, so I'll be dithering manually.

    I took a time-lapse exposure of my SB's meters and it looked like, at least toward the middle of the meter's arc, that the needle "rotated" one degree per image. This would indicate that the movement is coarser toward the ends of the meters. (I haven't photographed it with the needle near the -20 mark. yet.) But a one degree movemment across the arc would require about 64 images. That's why I'm wondering if the movement's coarser toward the ends.

    I guess I really need to look at your file(s).

    Re: Analog VU Meters

    Jon,

    I emailed you a vanilla .bmp (as I was able to open the zip) you might want
    to check your anti-spam filters it might have been thrown away.
