cool. thanks. Adrian suggested last year a ready-to-wear IMU that went for ~ $200- $250. Can’t recall the make. Xin Wei

I am sure they are good for something but I can't use them for various
reasons.
They just aren't reliable enough unless the performers are out of reach
of RF noise from the
audience/ambient sources.
+ Slow, old atmega cpu with too little memory,
+ old accelerometer instead of full IMU.
There are lots of smaller form factor things in the works like SparkCore
and all the bluetooth LE things coming out.
The problem is you have to look at the fully integrated size with
battery, the additional sensors you actually want, the case
etc etc. Small is 6 months away (BLE), small and fast enough for serious
movement work is still a few years away.

Are these xBees any good? would these be superseded by other common wireless microprocessors …?
We (at Synthesis and AME) are happy with the xOSC boards,
tho I do hope for a much smaller form factor.

Seriously, how do we think techniques of observation together with techniques of performance? I know it may be confusing to use those pair of terms -- observation and performance...
we need a better vocabulary that retains some of the mechanisms of entanglement from quantum mechanics, but not this dualism.

Hi allThere is some interesting work in sky lights in amplifying light amplitude. Can I suggest someone take a look at that area? Networked Prisms might be an interesting approach for instance. Perhaps they could be servo/stepper motor controller to redirect light streams into different parts of the space. Modeling this would be an interesting exercise. .
Cheers GarthSent on the MoveI love the idea. But we explored that in TML circa 2002-2004 in Atlanta, and circa 2005-2006 in Montreal.I’m happy to review the techniques that we investigated, all of which involved more labor than available without access to maquiladora hands.It’s worth Matt or Kevin posting the architectural techniques that are in actual use for light guides. Apparently the solutions cost nontrivial $ or labor. James Turrell has apparently made some study of this ...Xin Wei

Hi all,I would also like to add some thoughts on using GoPro. Well to begin with, I am a huge fan of GoPro cameras, and I was testing GoPro Hero 3+ Black Edition (the latest model) last April. It would be great if AME purchase new GoPro cameras but maybe it is not the best choice for Brickyard projects.<1012591_10152839329222119_7096611735257331402_n.jpg>
[Image 1] Six GoPros on a special mount made from a 3D printer. Didn't really work under Arizona weather. Photos taken near Tempe.
As far as I remember, ideas of using GoPro cameras started because we wanted to locate cameras outside of the building without any wires connected to the computers.GoPro cameras are small, light weight, feature loaded, and are designed to be put under extreme conditions. However, as they are not built for long-term use, they have battery issue, overheating issue, and Wifi range issues. Battery last less than an hour, and if we connect a source of electricity the camera will overheat and turn off once a while.I also found ways to stream full video into a web browser or VLC media player (https://www.youtube.com/watch?v=RhFzrYBXItc) and a Mac app controlling and doing low resolution live previews (https://www.youtube.com/watch?v=au5Yi6y-LmE). Unfortunately, most of these solutions are for low resolution previews. Trying GoPro cameras in Max/jitter might still be a very interesting and challenging project, but we can also consider different options.For example, wifi network cameras can be another good choice. They are designed specifically for long-term live streaming without being connected to the computer. Whenever the camera is connected to power source and network, it doesn't even need to be located near the computers. Image below shows my previous project that used two network cameras in an outdoor environment.<Camera and Interaction Elevation View.jpg>
[Image 2] Network camera was located outside of the building. All the machines controlling the LED ceiling were in a different building so we couldn't use wires to connect camera to computer.
Please let me know your ideas and thoughts.
Much appreciated,CooperOn Fri, Jun 27, 2014 at 9:21 AM, Sha Xin Wei <shaxinwei@gmail.com> wrote:Very likely standard httpd would be a bad way to send video since it was designed for sending bytes of characters or a few embedded media objects. But Max jit.* used to read rtsp video streams as well ( in the syntax rtsp:// ? )Such long latencies would make GoPro impossible for synchronous action, but we should also think about how to intercalate activity based on durational rhythm, not point-sync’d instantaneous events.Also, time delaying the feed by 3 hours would be interesting first step to intercalating Montreal and PhoenixXin WeiOn Jun 26, 2014, at 9:41 PM, Garrett Johnson <gljohns6@asu.edu> wrote:There is a browser object in max.

Garrett L. JohnsonMA musicologySynthesis Center research teamArizona State UniversityShould have forwarded to the group initially:Doing some initial research which I will present to the group. On the Go Pro:While the wireless feature is designed specifically for controlling and doing low resolution live previews on the Go Pro app, there is a way to stream full video into a web browser via the camera's built in web server. If any applications that synthesis is using can access this kind of stream (via http://) we should be able to grab video. A caveat is that the live streamed video has very significant (seems to be > 1 second) lag. This is likely dependent on resolution, and I would guess 720p video would have less lag than 1080p - but we'd have to try it to see.Also, it looks like there is a cable that allows us to both insert an external (3.5mm) microphone AND still utilize the camera's USB port as a power input as to avoid running off the battery.Here is a video that a youtube user posted covering the video streaming accessibility: https://www.youtube.com/watch?v=Y1XaBJZ8XcgTain
