Trillion Frames Per Second Camera – The Photon Catcher



        Researchers at the Massachusetts Institute of Technology (MIT) have always had the legacy of doing things that were so called “impossible” by the rest of the world. Recently they came with an idea of a new imaging system that can capture photons at a rate of one trillion frames per second. Yes, you heard it right. Now we can capture the video of the fastest known particle in the universe, the photons. This virtual slow motion camera captures the video of photons traversing through space. This high-speed camera is more than enough to produce a slow motion video of light travelling through objects.

An interview with Apple co-founder Steve Wozniak

     
      
      He is the “other Steve”, but to geeks around the world, he is the real deal; the man who practically invented the personal computer and changed the world. Steve Wozniak, supreme geek of the 1970s and the maker of the Apple II computer which brought about a worldwide computer revolution, was in Bangalore on Saturday to speak to a bunch of young entrepreneurs and achievers of the Young Presidents Organization who wanted to hear the story of the most-loved technology brand in the world — Apple.

      Wozniak co-founded Apple Computer (now Apple, Inc) in April 1976 along with Steve Jobs and Ronald Wayne. Both Apple I – the company’s first product – and the hugely successful Apple II (arguably the world’s first fully-loaded personal computer) were designed by Wozniak making him – and not Jobs – the darling of geeks around the world.

Simple SD Card Audio Player with an 8-pin IC

    This is a simple SD audio player biult with only an 8-pin microcontroller. The ATtinyX5 series (25/45/85) 8-pin AVR microcontroller has two fast PWM outputs in 250kHz carrier frequency. This enables to output a wide frequency range audio signal. I built an audio player with the 8-pin AVR and an SD memory card (SDC). The SDC can be controlled with only six lines, two for power supply and four for control signals. It can also be easily attached to 8-pin microcontrollers. The main application of the tiny X5 series AVR seems SMPS and related according to its integrated peripherals.

    Anyway this audio player is very simple and a few wires to be solderd so that it is suitable for brief soldering work before breakfast.



Hardware

   Right image shows the world's smallest audio player (as MicroSD player, perhaps...). There are three schematics for the player in different configurations. The recording media to be used is a MicroSD. Of course the standard SDC and MiniSD can also be used by proper socket conversions.

Capacitors

Function
Capacitors store electric charge. They are used with resistors in timing circuits because it takes time for a capacitor to fill with charge. They are used to smooth varying DC supplies by acting as a reservoir of charge. They are also used in filter circuits because capacitors easily pass AC (changing) signals but they block DC (constant) signals.
Capacitance
This is a measure of a capacitor's ability to store charge. A large capacitance means that more charge can be stored. Capacitance is measured in farads, symbol F. However 1F is very large, so prefixes are used to show the smaller values.
Three prefixes (multipliers) are used, µ (micro), n (nano) and p (pico):
  • µ means 10-6 (millionth), so 1000000µF = 1F
  • n means 10-9 (thousand-millionth), so 1000nF = 1µF
  • p means 10-12 (million-millionth), so 1000pF = 1nF



Potentiometer

IMG_0736

Potentiometer (Pot) is another class of variable resistors and is used as an adjustable voltage divider. It consists of a fixed resistance track having connections at both ends and a sliding contact, called wiper, which moves along this track by turning the spindle. If only one of the connections and wiper are used, it behaves as a variable resistor or rheostat. In case wiper is not used, it will offer fixed resistance across the two connections. They are specified by their fixed value resistance.



Condenser Microphone



Condenser microphone (mic) is a transducer that uses a capacitor (or condenser) to convert acoustical energy into electrical energy. The sound waves result into electric signals that can be used to drive a circuit or device. The pin connected to the case of mic is connected to ground and the other pin gives the output.


Ulka Pind or something else ?
