No, but I can take them apart and modify them so they will be.

Threw the body together with a couple servos, NiMH battery pack, chop sticks and some other parts laying around the house. Currently it is setup for popping on a Tinkerforge Master and Servo brick. A WIFI extension will be used to control this bot using my computer and WIFI router. I will also program an ATmega8 AVR for use in controlling this thing. If you have any more ideas on what I can do to it, let me know.

I was thinking you guys would have it set up where I would have to have 2 wifi extensions... one connected to the computer and another connected to whatever im running with wireless. Now I see that I just need one wifi extension which is awesome. So when connecting to the wifi extension, do I need a brick connected whatsoever to my computer? Or do I just use brickv to connect to my wireless router and control everything from that?

Is there an easy way to have a brick/bricklet function without being powered by a computer? Or would we just have to rewrite the firmware?

At the moment I only have the master brick, io16, breakout, and some sensors. I am wanting to control a couple servos I have laying around. This is the model of the servo...http://www.servocity.com/html/hs-311_standard.html
I'll probably end up buying the DC brick later but until then, is there any way I could use the master brick to send pulses or anything? I'm pretty new to this stuff.
I would be powering the servos with a separate battery pack.

I reinstalled MySQL and got it working.
This is the output I get with that command...
Installed packages, channel __uri:==================================
Package Version State
Tinkerforge 1.0.11 stable
Now, when I open the page ExampleCallback.php which I have placed on my Apache server, it does nothing but display a blank page.
My host, port, and uid are correct...
$host = 'localhost';$port = 4223;
$uid = '5Jj'; // Change to your UID
I've played around with these settings within the PHP file...
require_once('Tinkerforge/IPConnection.php');require_once('Tinkerforge/BrickletAmbientLight.php');
use Tinkerforge\IPConnection;
use Tinkerforge\BrickletAmbientLight;
I'm thinking my problem may be permissions or something? or something to do with the ports?
I have run this command to set permissions...
find . -type f -exec chmod 644 {} \; && find . -type d -exec chmod 755 {} \; -
Ive been using parts with Python but now want to start playing with PHP.
When I run the command "pear install Tinkerforge.tgz" I get this error...
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/mysql.so' - /usr/lib/php5/20090626+lfs/mysql.so: cannot open shared object file: No such file or directory in Unknown on line 0PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626+lfs/mysqli.so' - /usr/lib/php5/20090626+lfs/mysqli.so: cannot open shared object file: No such file or directory in Unknown on line 0

Ignoring installed package __uri/Tinkerforge
So does this mean I need to install MySql in order to use PHP with the bricks/bricklets?

Temperature Sensor
Using the io16 and temperature bricklet along with with a master brick from Tinkerforge, I have created a simple temperature sensor project which outputs its' readings to LEDs on a breadboard. The red LED lights up during warmer temperatures and the yellow LED lights up during cooler temperatures.
#!/usr/bin/env python # -*- coding: utf-8 -*- # Temperature Sensor using IO16 and Temperature bricklets import os HOST = "localhost" PORT = 4223 UID = "xXx" # Change to your UID for IO16 bricklet UID2 = "xXx" # Change to your UID for Temperature bricklet from tinkerforge.ip_connection import IPConnection from tinkerforge.bricklet_io16 import IO16 from tinkerforge.bricklet_temperature import Temperature ipcon = IPConnection(HOST, PORT) # Create IP connection to brickd io = IO16(UID) # Create device object ipcon.add_device(io) def cb_temperature(temperature): running = True while running: temp = str(temperature/100.0) if str(2650) < temp: io.set_port_configuration('b', 1 << 0, 'o', False) # Set pin 0 on port b to output low io.set_port_configuration('b', 1 << 7, 'o', True) # Set pin 7 on port b to output high os.system('clear') # use 'clr' with Windows print 'Hot' # display status print (str(temperature/100.0) + ' °C') # get reading return elif str(2650) > temp: io.set_port_configuration('b', 1 << 0, 'o', True) # Set pin 0 on port b to output high io.set_port_configuration('b', 1 << 7, 'o', False) # Set pin 7 on port b to output low os.system('clear') print 'Cold' # display status print (str(temperature/100.0) + ' °C') # get reading return else: print 'Reading' return if __name__ == "__main__": t = Temperature(UID2) # Create device object ipcon.add_device(t) # Add device to IP connection # Don't use device before it is added to a connection # Set Period for temperature callback to 1s (1000ms) # Note: The callback is only called every second if the # temperature has changed since the last call! t.set_temperature_callback_period(1000) # Register temperature callback to function cb_temperature t.register_callback(t.CALLBACK_TEMPERATURE, cb_temperature) raw_input('Press key to exit\n') # Use input() in Python 3 ipcon.destroy()

I just added to the Python section. I wish there were more English speaking people on here. I think its confusing because the forum defaults to German or some other language.

Done. Although I'm new to the Wiki stuff so I'm sure someone can make it look better. I'll add onto it as I play with Python more.

I'm learning Python so I wrote some scripts for the Ambient Light and Linear Poti bricklets. This may be useful for people who are new to programming.
This gives a basic idea on how to use the bricklets as a switch.
Ambient Light:
#!/usr/bin/env python # -*- coding: utf-8 -*- import os HOST = "localhost" PORT = 4223 UID = "xxx" # Change to your UID from tinkerforge.ip_connection import IPConnection from tinkerforge.bricklet_ambient_light import AmbientLight # Callback function for illuminance callback (parameter has unit Lux/10) def cb_illuminance(illuminance): less = '''Light.\n oooooooooooooooooooooooooo\n oooooooooooooooooooooooooo\n oooooooooooooooooooooooooo\n oooooooooooooooooooooooooo\n oooooooooooooooooooooooooo\n oooooooooooooooooooooooooo''' more = '''Dark.\n --------------------------\n --------------------------\n --------------------------\n --------------------------\n --------------------------\n --------------------------''' running = True while running: # Test with print('Illuminance: ' + str(illuminance/10.0) + ' Lux') lux = str(illuminance/10.0) if str(49) < lux: os.system('clear') print less break if str(51) > lux: os.system('clear') print more break if __name__ == "__main__": ipcon = IPConnection(HOST, PORT) # Create IP connection to brickd al = AmbientLight(UID) # Create device object ipcon.add_device(al) # Add device to IP connection # Don't use device before it is added to a connection # Set Period for illuminance callback to 1s (1000ms) # Note: The illuminance callback is only called every second if the # illuminance has changed since the last call! al.set_illuminance_callback_period(1000) # Register illuminance callback to function cb_illuminance al.register_callback(al.CALLBACK_ILLUMINANCE, cb_illuminance) raw_input('Press key to exit\n') # Use input() in Python 3 ipcon.destroy()
Linear Poti:
#!/usr/bin/env python # -*- coding: utf-8 -*- import os HOST = "localhost" PORT = 4223 UID = "xxx" # Change to your UID from tinkerforge.ip_connection import IPConnection from tinkerforge.bricklet_linear_poti import LinearPoti # Callback function for position callback (parameter has range 0-100) def cb_position(position): less = '''Switch Off.\n -------------\n -------------\n -------------\n 0000000000000''' more = '''Switch On.\n 0000000000000\n -------------\n -------------\n -------------''' running = True while running: # Test with print('Position: ' + str(position)) slide = str(position) if str(49) < slide: os.system('clear') print less break if str(51) > slide: os.system('clear') print more break if __name__ == "__main__": ipcon = IPConnection(HOST, PORT) # Create IP connection to brickd poti = LinearPoti(UID) # Create device object ipcon.add_device(poti) # Add device to IP connection # Don't use device before it is added to a connection # Set Period for position callback to 0.05s (50ms) # Note: The position position is only called every 50ms if the # position has changed since the last call! poti.set_position_callback_period(50) # Register position callback to function cb_position poti.register_callback(poti.CALLBACK_POSITION, cb_position) raw_input('Press key to exit\n') # Use input() in Python 3 ipcon.destroy()
breakout board explanation?

**Edit > when trying all the pins, I notice the SCL pin on the breakout board seems to give me the most accurate temperature reading, is this correct?
I'm playing with the breakout board and I have it connected to the Temperature brick.
I have the 5V and GND pin connected to the 5V and GND on my Arduino Leonardo board. Now in my Temperature Sketch with Arduino, I am using the Analog pin A0 with my Arduino. Which pin on the Tinkerforge Breakout board do I need to connect A0 to in order to get a correct temperature reading?
Here is my Arduino sketch...
