Simply add hosts into a list, and the program will ping each host, great for monitoring several hosts. You can also adjust max delay time before a host is considered as down, also increase or decrease ping interval.

News in 1.2:

- New: File, New option.
- New: Shows average delay.
- New: Uptime in percentage.
- New: Option to remove host after specified failed pings.
- Bugfix: duplicate ip possible.
- Bugfix: Several small adjustments & bugfixes.

It’s a realism server, so nothing will be spawned.

Whitelist is not enabled, but we run permissionsEX. So that anyone new can join to have a look. If you want to join please write a littlebit about you in this forum post: http://stigern.net/forum/viewtopic.php?f=8&t=3

Common sense is our main rule!

We use the following plugins with bukkit:
PermissionsEX (WorldGuard, WorldEdit, ChatManager)
LWC
Multiple Homes (Personal homes to tp to)
DynMap & DynMap WorldGuard
ChopTree (More realistic chopping down trees)
MineBackup

Map has been reset only a couple of days ago.

Rules:
1. No Stealing & Griefing
2. Do not harass or disrespect members.
3. Do not lit forest on fire, if you need to. Ask a Mod or Admin for permission and plan it wisely.
4. No Cheats(noclip, x-ray, item spawner, etc).
5. No Random Attacking. PVP is only allowed if both parts agrees.
6. Chop down a tree? Please plant a few new, unless it’s in a thick forest.
7. Random building without any reason isn’t allowed.(ex dirt houses)
8. Respect others creations, do not build only 1x block from their houses etc.
9. Use roads and connect, if you build close to a existing road.

Server specs:
Core2Duo E8400 @3Ghz

The idea for now:

You got a grid 5×5 with “fields” that can be bought and built into a base. Each base contains farms, food, soldiers, cannons. Farms give food for the soldiers, food can also be sold which is the main income atm. There are also citizens, which generate income from each field.

Give it a try and see if you can beat the AI.

Update: Pings 1.1 is done, changelog from 1.0:

- Stability issues fixed
- Major improvement in performance (Asynchronous ping)
- Ability to run on Synchronized pings too
- Save & Open your hosts list
- GUI rework
- Always on top option
- Color themes

Well, after a couple of weeks it arrived in the mail. And here are a few things I noticed:

Looks like it’s rusted and kind of old?

Not even close to nice solderings…

Some plastic is melted off?

Well, its not worth that much and it actually works, but for how long?

Whats most annoying is how the seller can say that its Quality and New!

DHT11 is a cheap and easy to use temperature and humidity sensor. But since it’s digital and only uses one pin there is a great library for it!

Of course it has some problems compiling on Arduino 1.0 and the one I found on the arduino.cc playground had problems. So I modified it, and put both the library and the example in a nice and easy to unzip package. The example sends data on serial back to the pc, so it looks like this when posting results:

Credit goes to the arduino playground for the library and example code.

Download Arduino DHT11 Sensor Library

Lets start with the C# sourcecode, it’s written in C# Express 2010 which you can download for free here. Get the C# project files:

Download CSharpEasySerialSource.zip

I tried to comment the code so that it should explain most of the stuff going on. But it’s pretty basic, you select the current comport then hit Connect. If you selected the correct port that the arduino is using it should now be connected. The textbox only takes numbers, writing text there will only result in it being converted to bytes.

When you click Send it will try to send the contents of the textbox to the arduino. In my example code I used “0″ and “1″ for turning off an on the LED. Lets look at the Ardunio example:

Source code

void setup()
{
  Serial.begin(9600);
  // Define the led pin as output
  pinMode(13, OUTPUT);
}
void loop()
{
  // Read data from serial communication
  if (Serial.available() > 0) {
  int b = Serial.read();
  // Note, I made it so that it's more sensitive to 0-40% load.
  // Since thats where it's usually at when using the computer as normal.
if (b == 1)
{
  digitalWrite(13, HIGH);
}
else if (b == 0)
{
  digitalWrite(13, LOW);
}
Serial.flush();
}
}

What the program does it’s listening on the serial port. And when it receives a “1″ pin 13 goes HIGH, and if it receives ”0″ it goes LOW. Pin 13 is in most cases a LED thats on the arduino board, so you only need a bare arduino to test it. And if you don’t know any C# and just want to use the program to control a arduino I’ve created a zip file containing only the .exe file for the program:

Basically it just reads the analog value from the mic and converts it to a 0-1023 value, but since the microphone sensor I got is meant for 12 volts, it only ranges from 0 – 5-600 on 5 volts. But it works just as good, only it’s not as sensitive as it should be. When playing music that is never a problem hehe.

The microphone sensor I use is one I found on eBay some time ago, just search for “Arduino Sound Sensor Module” they cost around 5$. And are very easy to use, only ground it and feed it with 5 volts and stick the output to a analog input on the Arduino. I’ll also post the program code for the Arduino, it’s the same thats used in the video below. If you want to make something like this yourself using my example, you only need 5 LEDs or more. And just wire them to the digital pins 2-5, and of course the mic to analog 0. Code example can be found in the bottom of this article.

Here is a video showing the LEDs blinking to the music.

Program code example:

Source code

int micValue = 0; // Store the readings here.
void setup()
{
// Settings the pins for output to leds.
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
}
 
void loop()
{
// Lets read from the mic
micValue = analogRead(0);
 
// Then choose what leds to turn
// on and off.
if (micValue > 410)
{
digitalWrite(2, HIGH);
 
}
else
{
digitalWrite(2, LOW);
}
 
if (micValue > 520)
{
digitalWrite(3, HIGH);
 
}
else
{
digitalWrite(3, LOW);
}
 
if (micValue > 580)
{
digitalWrite(4, HIGH);
 
}
else
{
digitalWrite(4, LOW);
}
 
if (micValue > 610)
{
digitalWrite(5, HIGH);
 
}
else
{
digitalWrite(5, LOW);
}
 
}

Ever since modified electronics stopped making the pico I’ve been looking for another arduino in the same price range and size, and now dx got just the right one.

- Digital I/O Pins: 12 (D2~D13)
- Analog Input Pins: 8 (A0~A7)
- TTL serial data receive and transmit pins: RX/TX
- PWM Output Pins: 6 (D3/D5/D6/D9/D10/D11)
- Microcontroller: Atmel Atmega328P-AU
- Small mini-B USB for programming and serial monitor (cable included)
- Supports external 5V~12V DC power supply or 9V battery
- ICSP header for direct program download
- Cable length: 108cm

Only problem I ran into when using it with arduino was the library, got some nasty compiling errors. So I changed a few lines in the library and made it work with Arduino 1.0 and older arduino IDEs.

Also wrote a little example for using it with a serial display:

Source code

#include <SoftwareSerial.h>
#include "Ultrasonic.h"
Ultrasonic ultrasonic(12,13);
 
SoftwareSerial mySerial(5,4);
 
void setup()
{
mySerial.begin(9600);
}
 
void loop()
{
mySerial.print("Distance: ");
mySerial.print(ultrasonic.Ranging(CM));
mySerial.println(" Cm.");
delay(250);
mySerial.print("?f"); // Clear display.
}
