Close xcode

You should be able to find the file xode created in
/Users/YOURUSERNAME/Library/Application Support/Xcode/Key Bindings
for me it is called Patrick.pbxkeys

Edit this file with the property editor.
From the view menu select :
Show Strings as Non-lossy ASCII

Add 2 children as follows

Save, and open up xcode

ctrl+shift+uparrow should now duplicate the current line upwards
ctrl+shift+downarrow should now duplicate the current line downwards

happy coding

I the wrote a simple sketch in Arduino:
Waiting for the character s on the serial-in and then setting pin 2 to HIGH for 1250 milliseconds, enough for the camera to focus
even when using the flash.

int outPin =  2;
 
void setup(){
Serial.begin(57600);
pinMode(outPin, OUTPUT);
}
 
void loop(){
checkSerialInput();
}
 
void checkSerialInput(){
if (Serial.available() > 0) {
// get incoming character:
char serialChar = Serial.read();
 
if (serialChar == 's'){
//shutter
digitalWrite(outPin, HIGH);
delay(1250);
digitalWrite(outPin, LOW);
}
}
}

I then figured that it would be nice if I could take the picture if I smiled at the camera.
Since I can’t loop the image from the eos 400d back into my mac, I used the webcam instead.

I found that someone else had already done “smile” recognition in openframeworks using opencv.
I just needed to add some lines to set up the arduino and write an ‘s’ to the serial port. And presto.
Smiling at the webcam took my picture.

Here’s the xcode project:
SmileAndClick

So what happens if take a compass module and tie it to the y-rotation of a camera..
well here is a video of me sitting on a desk chair with my laptop and the compass on an seeeduino.
[ sometimes macbook interferes with the compass! especially when I placed the compass over the HD ]

Raw microphone access in Air 2.0

I was asked to build the videoplayer and videobrowser.
This was my first project that used Zend_AMF instead of AMFPHP,
and also the first time I worked with the Zend-framework.

Go take a look Here:
http://www.xite.nl/

Getting everything nicely readable in perspective view was the main problem.
It’s a dutch website built around a poetry art-project.

So far all my apps seem to be running just fine.

I’ll be keeping a list here for all minor/major tweaks that were necessary to get everything running.

Enabling PHP and MYSQL

First of all edit /etc/apache2/httpd.conf and uncomment the following line
loadModule php5_module      libexec/apache2/libphp5.so

Next install Mysql, get the latest version (now still says osx 10.5, but it will run!)
http://dev.mysql.com/downloads/mysql/5.1.html#macosx-dmg

copy php.ini.default to php.ini  (don’t forget to make it writable first)

edit default_socket properties: I’m using pdo so I had to change the following line
pdo_mysql.default_socket=/var/mysql/mysql.sock
to
pdo_mysql.default_socket=/tmp/mysql.sock

edit the default timezone, i.e:
date.timezone = Europe/Amsterdam

edit some properties like upload size memory limit

start mysql , add at least one user since by default there’s only root without a password
(use sequel pro, It’s a nice opensource and free DB-tool)

now restart apache
sudo apachectl graceful

… you can now develop local php-sites

…..
more to come…..

After a succesful test, I quickly hacked a swf-module that could be loaded into version 2 of the Ukulele Chord Finder ( version 1 can be found at http://www.ukulele.nl ) that we have under development.
So now we can talk to Merapi Straight from the browser.

I also managed to turn the Java Side of the Merapi-Bridge into a Mac application.
So here’s a video of the things I made.

The Arduino with Protoshield and Breadboard with ledmatrix

On the left we have an Arduino Decimila with a prototypeshield on top.
The prototypeshield contains a max7221 ic 2 capacitors and a resistor.
The breadboard contains 64 leds in a 8×8 matrix.
I was aiming for a 4×16 setup, but there was no way I could get the wiring done on one 1 breadboard.

The 8×8 ledmatrix

So far this is just a worked out example of : http://www.arduino.cc/playground/Main/MAX72XXHardware

The Arduino is now running a simple loop.
Next stop is writing an intelligent layer like firmata.
So more to come soon……

[See post to watch Flash video]

I got myself a max7221 IC and hooked it up to the arduino board.
I’m now thinking of good way to wire the 4*16 matrix
basically a 8×8 matrix but the physical postion of the odd rows is behind the even rows.
Designing this matrix on a breadboard sucks (too many wires), so I need to come up with a better way without soldering.  (suggestions welcome)
