sharepoint 2013 / Exchange 2013 ediscovery

Definition of the search languages

To set documents on litigation hold, you need to define a search query belonging to a matter. New content created after that query ran, is not automatically put on litigation hold. Therefore a functionality is needed to run that queries again. Maybe this apis give a hint on how to achieve this:

The programming model around sharepoint knows an object “saved search” that can be updated. THis can also help to automatically put new content that hits the case criteria on litigation hold:

DCF77 time receivers

This are links to sides discussing software (mostly on the AVR microcontrollers) and hardware to receive the radio signal and get the time from it. The hardware links have a focus on the module found at

Description of a project by mathias wilhelm. He directly connects the module to the mc.

jmlietaer has written a library using an analog pin, seems to make sense for the pollin module, cause it needs to be powered at 3.3 volt and the ardurino has 5 volts. When using the lm324 opamp driver from the output is also 3.3 Volt.
Normaly that should be sufficient, but it is worth a try.,7858.0.html,16459.0.html

Sketch to scan for the adress of devices connected to the i2c bus:

I got a cheap I2C interface for character LCDs I wanted to use with the arduino duemillanove from ebay. The seller was emall4you. The board is fine but the description was wrong. The sample code said to use the i2c adress 20 but the board needed 27. The sample also said that some changes to the liquidCrystal_I2C code are needed. I didn’t get the beast running . What saved me is a piece of code in a discussion (,183775.0.html ) that showed the usage of a differnt lib and the correct initialisation.

Code snippet:
#include <LiquidCrystal_I2C.h>

#define I2C_ADDR 0x27
#define En_pin 2
#define Rw_pin 1
#define Rs_pin 0
#define D4_pin 4
#define D5_pin 5
#define D6_pin 6
#define D7_pin 7
LiquidCrystal_I2C lcd(I2C_ADDR,En_pin,Rw_pin,Rs_pin,D4_pin,D5_pin,D6_pin,D7_pin);
