THE KNOB II – Wifi-Hardware

You know, I’m addicted to rotating knobs. And this is my new version. This one works over Wifi. So it works for desktop and mobile, native and Adobe Air. It is build with an Arduino Leonardo, a RedFly Wifi Shield and a ProtoShield with 10 buttons, 1 rotary encoder and 3 LEDs.

On the software side I’m using the OSC protocol over UDP which is very fast and responsive.

Adobe AIR 3: How to build a Captive Runtime, Standalone Bundle Executable App

The challenge was to build a Adobe Air 3 Standalone Executable. Also called a „Captive Runtime“ or a Bundle.

Here are some better descriptions:

But it was not so easy as it sounds because the order of the adt options are very important!

If the order isn’t correct you get the error „-storetype is required„.

And if you are behind a firewall or no internet connection, the timestamp server isn’t reachable. So use „-tsa none“ if you get „Could not generate timestamp: Connection timed out: connect„.

Here is my ant task which do the job with the correct order. But the order of the options in a terminal command should be the same.

<target name="07. [package exe]">
	<mkdir dir="${publish.dir}"/>
	<input message="certificate password:" addproperty="certPassword" />
	<java jar="${sdk.dir}/${adt}" fork="true" failonerror="true" dir="${deploy.dir}/">
		<arg value="-package" />
		<arg value="-keystore"/>
		<arg value="${air.certificate}"/>
		<arg value="-storetype"/>
		<arg value="pkcs12"/>
		<arg value="-storepass"/>
		<arg value="${certPassword}"/>
		<!-- <arg value="-tsa" />
		<arg value="none" /> -->
		<arg value="-target" />
		<arg value="bundle" />
		<!-- Name Of File To Create-->
		<arg value="${publish.dir}/${publish.exe}" />
		<!-- App Descriptor-->
		<arg value="${application.descriptor}" />
		<!-- Files To Package -->
		<arg value="Icon*" />
		<arg value="Default*" />
		<arg value="iTunesArtwork.png" />
		<arg value="-C" />
		<arg value="${deploy.dir}/" />
		<arg value="${deploy.swf}" />

Hope this helps some people having the same problems.

Gas flow simulation through tubes with stardust particle engine

The Challenge: Simulate the flow through the tubes in a medical device. The device is a anesthesia workstation where three different gases are mixed. The device has two main working modes, manual ventilation and controlled ventilation. We had to find a solution to show the flow between the parts in different situations in a very understandable way. We designed a schematic version of the devices‘ tubes. And now it was my part to simulate the gas through the tubes.
