Some impressions on the Google Tango Hackathon held in Timisoara in April 2014. See one of the Winner projects, the Camera 3D and some insight on the new device from Google.
Applications released as unlockable trial versions are vulnerable. Learn how to protect your work by embedding bulletproof security techniques.
You can use your smartphone (android/iphone) to control electrical equipment inside your home. See how.
This page has been created to report unusual activity (radiation, temperature, humidity, luminosity, barometric pressure), as recorded by the uRADMonitor, including all the debug data to support the results. I cannot guarantee the measurement precision, I merely present the data recorded by the instruments.
I’ve developed the uRADMonitor as an Environmental Radiation Surveillance automated monitoring device. Data is gathered in real time, 24/7, and is exported via the Internet to a database online. The data is available in customizable charts for analysis.
Learn how to do a programmatic screen capture on Android, using the framebuffer and some native C code. See how to correctly save a BMP file.
Learn to connect a bluetooth module to an ATMega micro controller via the UART serial interface and even further, discover it using a bluetooth enabled Android phone. The 9600bps serial link established, can than be used to exchange data: read sensors or control the robot.
See the real limit for receiving a SDP bluetooth device attribute in the SDP_DISC_ATTTR_VAL structure for the Broadcom Bluetooth Stack.
