Windows Android: error updating SDK tools revision 16

By |2016-01-12T21:08:57+02:00December 17th, 2011|android, technology|0 Comments

There is a possibility that SDK fails to update. This is a known issue since revision 8: http://code.google.com/p/android/issues/detail?id=11989 Normally, you will be informed by the Android SDK Manager Log: Downloading Android SDK Tools, revision 16 Installing Android SDK Tools, revision 16 [post_tools_install.bat] Updating SDK Manager.exe [post_tools_install.bat]         0 file(s) copied. [post_tools_install.bat] Error: The process cannot access the file because it is being used by another process. [post_tools_install.bat] Updating AVD Manager.exe [post_tools_install.bat]         1 file(s) copied. Installed Android SDK Tools, revision 16  The solution is simple: Ensure that your Explorer is closed and not/or not listing your SDK tools folder. It seems that explorer locks tools. Open a CMD window and go to your SDK tools folder. Run android.bat

monome: adaptable, minimalist interfaces + open source

By |2017-12-04T21:42:15+02:00November 7th, 2011|design, electronics, Interaction Design, user experience design (UX)|0 Comments

Monome are a small company based in Philadelphia, who design and build a range of controller/display boxes that can be interfaced to music software. That in itself isn't too remarkable — the market is awash with fader units and mixing surfaces of various shapes and sizes — but Monome units are something different. Read a thorough review here. monome is brian crabtree and kelli cain. They do minimalist interfaces. They are minimalists. http://vimeo.com/8301567 http://vimeo.com/14955241

LEDs & resistors

By |2016-01-12T21:09:35+02:00April 18th, 2011|electronics, technology|2 Comments

  To calculate the resistance when powering a LED use this: R=(Vpow-Vled)/I R: is the needed resistance Vpow: is the voltage of our source or power supply (e.g. battery) Vled: voltage of the LED I: the maximum of current that goes through our LED. for a 2V (diode forward voltage) LED we need 20mA =0.02A (diode forward current) So, for instance, if we have a 12V battery then: R=(12-2)/0,02= 10/0.02=500 Ohm Another example is the use of multiple LEDs in an array. So, for an array of 4 LEDs with diode forward voltage 2V, diode forward current (0.02mA) and a Vpow of 12V we need: 4 x 1 array uses 4 LEDs exactly +12V R = 220000 ohms each 220000 ohm resistor dissipates 0.088 mW the wizard says the color code for 220000 is red red yellow the wizard thinks 1/4W resistors are fine for your application together, all resistors dissipate 0.088 mW [...]

CyanogenMod 7.0 stable is out

By |2016-01-12T21:09:35+02:00April 11th, 2011|android|0 Comments

CyanogenMod 7.0 stable version is now available: 1, 2 It includes Android 2.3 Gingerbread stock platform (actually Android 2.3.3), app2sd capabilities, root access, incognito mode for the Android Browser, CPU frequency adjustments and clocking through governor selection, OpenVPN & SIP, USB/WiFi/Bluetooth tethering, FLAC support, an FM Radio player, play/pause with camera buttons, trackball wake and a number of features, changes and enhancements over the original rom. There are some issues still that I have identified, most of them comming from the original Android 2.3. For me these include: Exchange/Corporate sync issue: 1 Bug in unchecking Background data box: Issue 2931 Answering delay: 1,2,3, (probably related to the exchange sync bug. both of them seem to be caused from the issue that causes receiving broadcasts to stop after some time.) CHANGELOG 7.0.0 Common: Android 2.3.3 (Gingerbread) - Google Common: Fixes and changes from AOSP master - Various Common: ClockworkMod Recovery 3.0: [...]

Setting up App Inventor for Android

By |2016-01-12T21:09:35+02:00November 30th, 2010|android, tutorial|0 Comments

This is a short description of how to setup your machine to run App Inventor for the Android platform. First of all you will need a computer with the following: OS: Mac (with Intel processor): Mac OS X 10.5, 10.6 Windows: Windows XP, Windows Vista, Windows 7 GNU/Linux: Ubuntu 8+, Debian 5+ Browser: Mozilla Firefox 3.6 and higher Apple Safari 5.0 and higher Google Chrome 4.0 and higher Microsoft Internet Explorer 7 and higher Test your Java You should ensure that Java is working. Download it from www.java.com and test it here. Mac users should use JRE 1.6 (Java 6). If you are unsure then: In the Finder, open the Applications > Utilities > Java folder. Run Java Preferences. Select the General tab. You'll see two version lists — one for Java applets and one for Java applications. In each list, drag the "Java SE 6" to the top of [...]
