HM2007...Simplest Hardware for speech Processing

                           Hi.......We all are use many risky programs for speech processing . Here is simple solution for this.We can done speech processing like a toy by using HM2007 processor and its training kit.There is no need to program.HM2007 is a single chip CMOS voice recognition LSI circuit with the on-chip analog front end,voice analysis,recognition process and system control functions.A 40 isolated-word voice recognition system can be composed of external microphone,keyboard,64K SRAM and some other components.Combining it with microcontroller we build an intelligent recognition system. 

The figure below shows the speech training circuit using HM2007

The Scala Programming Language

                  Freands..... Today I'm just trying run Hello world program using scala. Here I just add sume basic information about scala for biginners                  
             Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages, enabling Java and other programmers to be more productive. Code sizes are typically reduced by a factor of two to three when compared to an equivalent Java application.

How to make an Automatic Street Light Controller Using MSP430 Launch Pad

           Hi..There is an idea to make a simple automatic street light controller bulb automatically glow at night and turn off at day time ,using MSP430 launch pad.But the problem is that it is complex compared to cheap existing technology (using LDR and comparator arrangement ),any way I'm happy because I need a simple program to work it. And I use the LED on the Launch Pad for light sensing. mhj The interesting fact I studied from here is that we can use the same LED as light sensing and to glow.

                     This robot searches the object we told , move towards and pick it.Here Matlab is used for speech processing and Image processing. The color of object is used for identification.I'm using the arrangement inside the CD player for making a simple arm.
