I am using an Arduino Uno running a 9 Degrees of Freedom Sensor Stick with a BlueSmirf Silver bluetooth module to wirelessly send the gyroscope, accelerometer, and magnetometer data to a processing sketch.
I would like to record and detect gestures so that I can send OSC messages to control various audio and video software. (I already know how to send OSC)
Are there any existing libraries that can take my data and analyze it against recorded gestures? I have looked into the ezGestures library however it seems it is only applicable to basic mouse movements.
Thank you!
James
For those of you who are interested I found a piece of software that handles this exactly.

Great for those of us who aren't computer learning experts.
Seeed Studio also made this gesture detection library available for free use.

I have a basic question. For microcontroller project , we need a compiler which support that specific microcontroller. But if compiler does not support a specific microcontroller then what does it mean? In other words ''Compiler support this microcontroller '' what it means? Any detailed description will be appreciated.
Thanks
The compiler transforms high level source code into lower level assembly instructions. Different families of CPU cores use different assembly instruction sets. For example, the Intel x86 instruction set is different from the ARM instruction set. A compiler that doesn't support a specific microcontroller cannot transform source code into that microcontroller's assembly instruction set.

I am looking for a turnkey solution for server monitoring, especially disk space usage that notifies of certain events such as a particular drive getting low on space via email, text or both.
The client has 11 machines that need monitoring and money is not an issue with them as they run a time critical operation.
Any insights from personal experiences would be appreciated.
Try either Zabbix, Nagios or Pandora FMS. They're all basic monitoring solutions that can help in a greater or lesser measure heavily depending on the infrastructure and the time as you mentioned. In your position, for that small amount of devices I'd try one out that has an Open Source edition like Pandora FMS or OpenNMS.

I have beacon which has Texas Instrument's BLE cc2541 chip in it. I want to reprogram its advertising packets. Is there any free TI tool available to reprogram it. I saw on there website and full packages are available, which is too costly rather i want only developement software to reprogram my beacon. Any help?
In order to reprogram the microcontroller of the SensorTag (cc2541), you need to download the TI BLE Stack from this link:
http://www.ti.com/tool/ble-stack
The "Project" folder in the stack includes a "SensorTag" project folder. There is a project file in this folder named "SensorTag.eww", where you can program the microcontroller in the way you want.
You need an IDE named IAR Embedded Workbench to open the project file and perform the embedded programming. Unfortunately, it is not open source, but you have 30-days free trial:

Recently I just started learning Arduino and now I'm starting a learning project on which I'd connect more than 2 Arduino Uno powered devices via WiFi-direct(no access point, rather P2P group) and make serial communication over those devices.
After searching for a while I wasn't able to find any suggestion for WiFi-direct(P2P) implementation with Arduino. Any guideline or help content would be highly appreciated.
Thanks :)
wifi-direct can only make connections to the access point.
A device can only connect to one access point at time.
Anyway you can have an arduino to provide wifi-direct and then use that arduino to command other microcontrollers trough SoftwareSerial library and bluetooth.

Does anyone know where a good LabVIEW Tutorial on Serial Connections (RS232).
Any help is appreciated.
Thanks.
Pretty straightforward example:
http://www.ni.com/white-paper/2897/en
There are some complete apps in the Example directory. First of all, make sure that you don't have any hardware issues and check your serial port settings in OS configuration.
I hope you know that you can test your RS232 communication by connecting the Rx directly to the Tx pin.
