    GOA HIRA

    Ghar -E- Hira (Cave of Hira) This Cave, the sanctum of the Holy Prophet Muhammad (peace be upon him), the place of His devotions and meditations and the sacred spot where the Holy Quran began to be revealed. The Cave is situated on mount Al-Noor on way to Mina near Makkah and its peak is visible from a great distance. Muhammad (peace be upon him) had jus stepped into the forty-first year of his life, when during a night in the month of Ramadan the first 5 verses of the Surah Al-Alaque were Revealed to him.

    Albert Einstein

    Albert Einstein Everything’s relative. Speed, mass, space and time are all subjective. Nor are age, motion or the wanderings of the planets measures that humans can agree on anymore; they can be judged only by the whim of the observer. Light has weight. Space has curves. And coiled within a pound of matter, any matter, is the explosive power of 14 million tons of TNT. We know all this, we are set adrift in this way at the end of the 20th century, because of Albert Einstein. We tend not to blame Einstein for the bomb, any more than we blame Nobel for dynamite. It wasn’t the gentle theorist but the generals of the world who forged e=mc2 into the most terrible dagger in human history, and hoisted that Damoclean blade irretrievably over our heads in 1946. By then, the world had al

    Boster Radio Penerima FM

    Monday, December 21, 2009 Browse Home Radio Pemancar/Penerima Rangkaian Boster Radio Penerima FM Rangkaian Boster Radio Penerima FM Boster Radio Penerima FM Here is a simple circuit of an FM booster that can be used to listen to programmes from distant FM stations clearly. This amplifier will pull in all distant FM stations clearly. The circuit is configured as a common-emitter tuned RF pre-amplifier wired around VHF/UHF transistor Q1. Skema rangkaian boster radio penerima FM 2SC2570. (Only C2570 is annotated on the transistor body.) Assemble the circuit on a good-quality PCB (preferably, glass-epoxy). Adjust input/ output trimmers (VC1/VC2) for maximum gain. All capacitors are ceramic and 50V is the standard but the 25V types work fine too. Trimmer capacitors Tr1 and Tr2 (22pF) ar

    Rangkaian Booster TV

    Rangkaian Booster TV This is circuit that can be used to strengthen the RF signals from a television antenna work at UHF frequencies in the range 450-800MHz. It has a gain of around 10dB and is suitable for boosting weak TV signalsSkema rangkaian booster TV sederhana The tuned circuit comprising the 15nH inductor and 2.2pF capacitor resonate in the center of the UHF band. The 2.2pF capacitor may be Exchanged for a 4.7pF or a Trimmer capacitor of 2-6pF to improve results. The approximate frequency response is shown below. N.B. This is a simulated response using the TINA program produced by using a swept input 20uV swept over the frequency range 400-800MHz. Output was measured into a 1k source and the frequency generator has a 75ohm impedance. The coil is half a turn of 18-20 SWG copper w

    Thermometer Digital

    Thermometer Digital At this thermometer circuit, the sensor (S8100) or diode (1S1588) is used as the thermo sensor. When using the IC thermo sensor, the thermometry to +100C from -40C is possible. Also, when using the diode, the measurement to +150C from -20C is possible. Both sensors are contained in the kit. This time, the thermometer circuit used the diode as the thermo sensor to measure more than +100C. ICL7136 is used for the thermometer and is measuring the change of the forward direction minute voltages of the diode by the temperature. The 3-1/2 digits liquid crystal display (SP521PR) is used for the display. The most significant digit can display only “1″. The consumption electric power of ICL7136 is very small and it is possible to operate about 3 months continuousl
