RIPPLE BUDS

                In our everyday life, we often face this problem, when we get stuck in a very noisy place or in the traffic and still have to receive very important calls which get inaudible eventually. To rescue from this pathetic problem, Seoul-based Korean earphone making company RIPPLE BUDS comes with an amazing solution and created an earbud which comes with an in-ear microphone. This in-ear microphone nullifies all the other ambient noises so that user’s voice remains crystal clear for always.
               Ripple Buds CEO, Shin Dusik, himself found this common problem to receive a call in a noisy crowded place or talking with a client while travelling which makes his conversation very difficult. Once Mr. Shin lost a client to an inaudible phone meeting and thus decided enough is enough and it was the high time to create a solution for this common daily problem. Ripple Buds started a kickstarter campaign in March 2016 which will be ending on 21st April 2016, to raise fund for the project and till date they got $343,724 with almost 3000 sponsors already.

 HOW DOES IT WORKS?

            RippleBuds is an earbud that features small speakers to transmit sound to the ears as well as transmit voice through built-in in-ear microphone designed to pick up the user’s voice directly from the ear, effectively eliminating any background noise and allowing both the caller and receiver to focus on one another’s voices without distraction.
         
Mr Shin's says that by  placing a microphone in the ear, "RippleBuds"technology reduces ambient noise by about 30 decibels, allowing the user's voice to be heard clearly even when they are in an extremely noisy environment.
'With RippleBuds, you can talk on the phone in a normal voice even while riding a motorcycle or attending a rock music concert, as well as control your connected home and car devices using voice commands.

         Currently, RippleBuds holds a total of 115 patents and intellectual properties in nine countries and has been granted numerous awards in recognition of its advanced technology and creative business ideas, including the New Radio & Broadcasting Technology Award, the Prime Minister’s Award, and the Grand Prize at the Korea International Invention Awards.

RASPBERRY PI

RASPBERRY PI:

WHAT IS RASPBERRY PI?

            The Raspberry Pi is a series of credit card-sized single-board computers developed in the United Kingdom by the Raspberry Pi Foundation with the intent to promote the teaching of basic computer science in schools and developing countries.
           Operating system are used in raspberry pi are Raspbian,Ubuntu MATE,Snappy Ubuntu Core,Windows 10 IoT Core,RISC OS,Debian,Arch Linux ARM.In Raspberry Pi there are various model present in it that are Raspberry Pi 2 model B was released in February 2015 and Raspberry Pi 3 model B in February 2016.
                  

GENERATION OF RASPERY PI:

             Several generations of Raspberry Pi's have been released. The first generation (Pi 1) was released in February 2012 in basic model A and a higher specification model B. A+ and B+ models were released a year later.
           All models feature a Broadcom system on a chip (SOC), which includes an ARM compatible CPU and an on chip graphics processing unit GPU (a VideoCore IV.
 

  RASPBERRY PI 2 OVERVIEW:

            The Raspberry Pi 2 Model B is the second generation Raspberry Pi. It replaced the original Raspberry Pi 1 Model B+ in February 2015. Compared to the Raspberry Pi 1 it has:
           A 900MHz quad-core ARM Cortex-A7 CPU1GB RAM
Like the (Pi 1) Model B+, it also has:
  • 4 USB ports
  • 40 GPIO pins
  • Full HDMI port
  • Ethernet port
  • Combined 3.5mm audio jack and composite video
  • Camera interface (CSI)
  • Display interface (DSI)
  • Micro SD card slot 
  • VideoCore IV 3D graphics core 
Because it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10
       The Raspberry Pi 2 has an identical form factor to the previous (Pi 1) Model B+ and has complete compatibility with Raspberry Pi 1.
