I had the same issue. My Dazzle DVC100 did not show up as a device. But after reading this post I found the device under the webcam and Debut records just fine. However I have no sound. How do I get sound?
I'm trying to set up an experiment using the SoundIn object to record
participants' responses. The problem I'm having is that every time I
try to run or generate, I receive the following error message:"A Fatal Error occurred while generating the initialization code for
the E-Object named 'SoundIn1'
Error Message: Unable to find sound capture device. Ensure that a
sound capture device is available."I've tried with both an external USB audio-recording soundcard and the
computer's internal soundcard, and I get the same error with both.
There doesn't seem to be any problem with the soundcards: E-Prime's
SoundOut object will play without complaint using either card, and I'm
able to record audio input in software other than E-Prime.If anyone has any experience of getting E-Prime to work with audio
input, I'd be very grateful for any suggestions as to what might work.Here is my set-up:E-Prime 2.0.8.22 Professional / Windows XP

Please submit this to PST Web Support at
, they strive
to respond to all requests in 24-48 hours. Then please do us a favor
and post back here with the result.Also, you might try upgrading to EP2.0.8.73 (Pro), any registered
user can download that for free from the PST web site. Glad to see
that you are still on XP, many of us have had trouble running EP2
under Vista, and I have not gotten any confirmed reports yet on
whether 2.0.8.73 or Win7 fix that.Thanks,

Sorry I'm slow replying. It turns out the solution is quite simple: in
order to enable sound recording (and use the SoundIn object) in E-
Prime, you need to enable the SoundCapture device in the experiment
(Experiment -> Devices -> Add -> SoundCapture). I'd managed to miss
this when I looked through the New Features guide - thought I'd post
this here in case anyone else has the same problem.While I'm here, I might as well clarify another quirk of the SoundIn
object. It turns out that regardless of when you stop the SoundIn
object, the WAV file it writes will always be the full length of the
SoundIn object's buffer (the remaining duration will be silent). I
asked PST Web Support about this and they say that at the moment there
is no way round this. Not necessarily a huge problem, but it does mean
that response data can end up taking up vastly more disk space than is
really necessary. I got round this problem by converting everything to
mp3 (since, as I understand it, silences - however long - should make
a negligible difference to file size when encoded to mp3). Since the
SoundIn object also currently always writes in stereo (even from a
mono input), I also converted back to mono when encoding to mp3, which
should halve file sizes as well. For anyone who wants to do this, I
recommend LamedropXPD - a very small, easy-to-use batch mp3 encoder,
which has a 'Mono encode' checkbox. This allowed me to reduce 128MB of
sound recordings to 4MB, with no audible loss of quality (I encoded at
192 kbps). Of course, anyone trying this would be wise to make sure
that all the resulting mp3s are useable before they delete the
original WAVs...Anyway, just thought I'd post all that in case anyone else is having
any of the same problems I had - hope it's of some use to someone.Thanks again,
Nick
_27590I don't think that will be reliable. It will get a subset of mobile devices but not all of them. I'm not sure what percent. For accuracy, you need to look them up using something like browscap.
Thanks TomG. I guess I didn't understand how to use the Browser Meta Info question. I thought that the values captured would show up in the response data immediately (mine are all blank). So I will have to create embedded data elements for the attributes I want to capture and pipe-in information from the Browser Meta Info question?
Still being a newbie to this platform, how (and where) exactly would I go about installing my own JavaScript?
Premiere Pro is not seeing my Canopus Firewire capture device. I do not want hdv because it is DV. If Premiere does not see the Capture device, it does not matter what camera is connected to it. It would at least see the device.
It would be really helpful with the ability in ArcGIS Online/Enterprise to rotate symbols using an attribute to capture the orientation of mobile devices in QuickCapture to an attribute.
The behavior I'm looking to create is to be able to activate a scene, and then when I turn the scene off, it will return to the previous state (I cannot in this situation create a scene for the previous state because it's never the same).
Also, is there any way to improve the performance of scenes? Even in a scene with only four switches, the Hubitat is painfully slow. I can't think of any reason as to why it would take more than a second to send an on, or an off message to four switches (it takes anywhere from 5 to 10 seconds).
Yes you can. What you will do is use the option to create a capture device to capture the current state of all of the lights before activating your selected scene. Then, whenever that is over, you can invoke the captured scene.
The capture device is a switch that will be created automatically when you select that option and save the scene. The device will be named the same as the scene with "capture" after it. Turning on that device will capture the settings for the lights included in the scene.
However, depending on when you are trying to do this, there are other ways to capture and restore. Namely the capture and restore functions built into Rule Machine. You can capture the state of devices and then after doing something else restore those devices to their previous states.
Question I have, is the capture option seems to create two devices: A "Scene Name" device and a "Scene Name Capture" device. I understand the second one. Any idea why the first exists and can it be deleted?
I have consulted the google quite a bit, but haven't found everything that I want to know. I'm specifically interested in using a Micro Trax, Kong Duck, or Ropeman to protect a 2nd falling while simul climbing. I know that a toothed device will damage the rope in the event of a fall. I'm just wondering to what extent, and how this can be minimized.
I understand that slack between the micro trax and the 2nd would increase damage to the rope. My question revolves mostly on how much damage the rope will receive. It appears that if the device was directly above the 2nd and there was no slack, the 2nd could essentially sit down on the device without causing harm. Can anyone offer information to contradict this?
On anther note, how will this device hold a fall in traversing terrain? I imagine if the 2nd takes a big swing with any amount of slack that is NOT good! What would happen if during a traverse, the leader placed a quickdraw on the first bolt of an anchor, then the next bolt had the progress capture device? The idea being that the quickdraw provides a directional and minimizes the distance the microtrax travels to align with the fall. It, however does appear that completely eliminating travel of the microtrax would be difficult. My understanding is that the device traveling is the primary cause of sheath damage during a TR solo set up. That's why a chest harness or two slings in the "X" configuration are used.
I know, I know, I'm going to die. I'm merely looking for information about how much damage will occur in the rope, and which situations damage it the most (or least for that matter)
the use of a mini-trax is more the protect the leader if the 2nd falls. If a fall by either climber is remotely likely, you probably shouldn't simul or at least give a belay at the crux.
Toothed devices can harm your rope even if you don't fall. For example, I recently learned the hard way that disengaging a mini-trax while it is slightly weighted (by the weight of the rope itself) can cause a sheath strand to catch on the one of the teeth.
That being said, I've taken short (>1 foot excluding rope stretch) and even traversing falls while TR soloing on a mini trax without sustaining any sheath damage. Obviously YMMV. If the rock is steep enough, though, the loop of rope exiting the mini-trax may be enough weight to pull up some of the slack for the 2nd because it doesn't take much weight for the mini-trax to feed automatically.
Jeff, not sure if you have seen my book during your searching, but in it I mention that if you think slack build up might be a problem the second can keep a grigri on the rope clipped to her harness to remove this slack.
Haven't done any simulclimbing so can't offer much input there, but sheath damage from toothed devices is something I have an opinion on as I've done a bit amount of solo TR (with petzl basic, microtrax).
I don't bother with a chest harness, and rather go off the belay loop so each fall is a small fall regardless of slack in rope, as the device moves from below to above the belay loop. Solo TR in itself has never damaged my rope. Like eli poss, I have caught sheath strands when trying to disengage the device when it's not fully unweighted - normally because I'm rushing through a changeover - I consider that my own user error more than anything, each time it's happened I've not at all cared about that level of sheath damage.
Thinking about how I'd go about simulclimbing, sheath damage from a microtrax is pretty low on my list of concerns.
