  • Thanks for the information; very helpful. I will have to do some more research, but I am afraid that even 3 ms would wreck ambisonic playback, especially if a source panned between the two board's respective speakers...might could do a six above and six below sort of arrangement inside a dodecahedron and just disallow pans that would cross the equator.

  • Question: I have an application in mind where I need 12 synced mono audio channels out (it's for ambisonic playback)...normally I would use a Mac Mini, a multichannel sound card and Max/MSP for this, but a Tsunami solution would be both more robust and more cost effective.

    Is there a way to set up a trigger for 6 tracks each on two Tsunami boards and then have them all start in sync from a single physical trigger...or a way to accomplish this via serial or MIDI signal? Thanks!

  • I have not used this particular sensor, but, based on my past experience with similar ultrasonic sensors, you will not detect a fluffy cat with it. (The sensors I have used before even struggled to detect clothed humans...naked humans (or shaved cats?) do seem to be reflective enough. YMMV).

    Of course, if you can shoot at a wall or other hard surface in a no-cat state and then look for a major change in that reading as the cat absorbs the sound, you might be in business...

  • Awesome idea!

  • Yep. Trying to imagine what rotating through the "hue" in a hue-saturation-value model that is expecting R-G-B LEDs would look like on these guys ... May just have to get some and try!

  • Is there an Arduino library that can deal with these strips being cool/warm/amber instead of RGB? Maybe FastLED could be extended/adapted? Would be super useful to be able to specify a color in degrees K and have the LEDs display it!

  • Great! Thanks.

  • Hi! The GitHub and Hookup Guide links are both 404-ing for me right now.

  • I am having trouble with trackGain() in the WAV Trigger library on an UNO. I can successfully trigger files using the library, but can't seem to change the gain. Maybe I am just being dense, can someone spot the problem with the following? The track always seems to play at the default volume. Many thanks...

    // ****************************************************************************
        #include "AltSoftSerial.h"
        #include "wavTrigger.h"
    wavTrigger wTrig;
    // ****************************************************************************
    void setup() {
    // ****************************************************************************
    void loop() {
        int trk = 1;
        int vol = random(-70, 1);
        wTrig.trackGain(trk, vol);
  • I have an oddball question: If I had multiple LilyPad MP3 units with matching SD cards and triggered them simultaneously, how much "drift" would there be in the playback start time from unit to unit? Would the offset be consistent each time the devices were triggered? And, if the offset could be measured and compensated for, would the playback (without external sync) stay together for a few minutes of playback time?

    Okay, that was several questions...

    Anybody done any experiments?

No public wish lists :(
