photo transistor circuit

The human eye was a  persistance of vision of about 0.02 second. Therefore a light that flashes on and off more than about 50 Hz appears continuously on. The human ear is much faster and can respond to sound with a frequency Up to about 20.000 Hz. The Light listener transforms the pulsating and flickering of light that eye cannot discern into sounds . The ear can easily hear.

b) Radiant Energy Patents - Various R. E. Circuits and Devices

1. Patent No. 2,813,242, Nov. 1957 L. R. Crump-Atmospheric Energy Device
This radiant energy conversion art is quite significant since it discloses three distinct conversion applications circuits which are both practical and worthy of further study and improvement.
The accompanying schematics show the three versions, along with the identification of each component within the three circuit diagrams. Of particular interest is the circuit diagram shown in FIG. 3, which is the high voltage D. C. conversion, using input coils, tuning capacitor, a transistor oscillator, transformer and diode circuitry. This arrange- ment should offer the best combination of components to produce a high potential output from a radiant energy source.
The circuit version shown in FIG. 2 is for a general low voltage, wattage arrangement which is simple and may be useful for certain applications. The circuit version shown in FIG. 1 is a direct transistor radio operational design, which is self-explanatory.
There is a general similarity of Cramp's work to that of Lester Hendershot, except for the addition of the antenna and diodes in Crump's art. It should be noted that the tuning capacitor in Crump's circuit is a desirable feature in any Radiant Energy device, since these circuits need to be "tuned" to R.E. frequency. Hendershot's permanent magnet/& clapper component is a desirable dynamic feature which might be used to advantage within the Crump circuitry, but this will require some experimentation before an optimum match is obtained.
The addition of the diodes in Cramp's circuitry increases polarization efficiency, and generally improves the R. E. conversion value of this device. It should be noted that it is believed that Dr. T. H. Moray also used antenna-coupled coils directly connected to his 100 foot long directional antenna, as the Crump input circuitry indicates.
In a general manner, the Cramp circuitry appears to bridge between the art of Moray and Hendershot in the selec- tion and application of the various components, as can be seen from a review of their circuit components.

2. Xtec Corporation, of New Britain, Conn, with reference to Crump's Patent above, (Pats, pending)
This group has developed an antenna/amplifier arrangement which is said to collect and amplify atmospheric/ra- diant energy. The antenna operates as a dependent power supply for the system. An input signal turns on the power amplifying antenna which draws on the potential between two points in the environment to complete a circuit through a form of inductive coupling. The result is amplified energy for the load to be driven.

Simple Diode Radio For Low Impedance Headphones

Diode Radio For Low Impedance Headphones - using small amount of component , germanium diode semiconductor you can build small radio equipment that can pick up lot of AM/LW/SW frequency . This project will talk about this purpose. if you ever look at construction notes for building old detector type radios the type of headphones specified always have an impedance of 2 X 2000 Q. Nowadays the most commonly available headphones have an impedance of 2 x 32 Q, this rel- atively low value makes them unsuitable for such a design. However, with a bit of crafty  transformation these headphones can be used in just such a design. To adapt them, you will need a transformer taken from a mains adapter unit, the type that has  a switchable output voltage (3/4.5/6/9/12 V) without the rectifying diodes and capacitor. Using the different taps of this type of transformer it is possible to  optimise the imped- ance match.

For the diode radio (any germanium diode is suitable in this design) the key to success is correct impedance matching so that none of the received signal energy is  lost. The antenna coil on the 10 mm diameter by 100 mm long ferrite rod is made up of 60 turns with a tap point at every 10 turns; this is suit- able for medium wavereception. If a long external aerial is used it should be connected to a lower tap point to reduce its damping effect on the circuit. 
You can experiment with all the available tapping points to find the best reception. With such a simple radio design, the external aerial will have a big influence.

After construction done, connect ground to water pipe/make the grounding your own. The Key is the good grounding, so there is voltage between the air radio signal from the grounding, and this radio signal picked up by this circuit. This is such building a Crystal Radio
