200 Watt power Amplifier for car by 2SC2922+2SA1216 Today we try to come to see the idea power Amplifier for Car. I sees this circuit , designed come to well. There is tall drive arrives at 200W is the character Amp OCL very be Class AB amplifier make good moderately sound. Besides still systematically protect excellent loudspeaker…..

200 Watt Modified PC Power Supply 13.5 Volt 14 AmpThe external 230 Volt AC power ON/OFF switch is removed and bypassed.Old unused outputs are removed. Over voltage protection changed to only protect one output at 16 V,Voltage regulating resistor net changed to only monitor a single output…..

200W MOSFET Amplifier Hifi audio powerhouse A compact audio powerhouse ideal for guitar or PA work or for use as a general-purpose subwoofer or hifi amplifier. Many people prefer Mosfets because of their legendary ruggedness. Altronics had a Mosfet amplifier module which produced 200W into a 4 Ohm load and so we decided to take a look it…….

Power Amplifier OCL 300W HIFI by transister For many application there’s no substitute for sheer power- low efficiency speakers, outdoor sound systems, or maybe you like the full flavour of the dynamic range of a high power amp. Whatever your requirement-this super power module should fit the bill……

240Watt Mosfet amplifier using BUZ23 At this empty period as a result seek Mosfet amplifier circuit keep give friends see in rows think out. For this time I meets this circuit , about 240watt. When use 4ohm – 8ohm loudspeakers which this circuit designed keep well……

1MHZ Digital Frequency Meter by IC 4026, 4007 , NE556 This circuit is a frequency meter, low cost. It covers region 1HZ until 1MHZ. The IC1 schmitt trigger that it regulates the signal of entry and him changes in reasonable level suitable for the IC2-3-4. With the tenth pulse in the entry of IC2/1, is produced a pulse ” carry ” in the IC3/5. The same moment the IC2 causes the depiction in the DIS1, show [0], the IC3 causes the DIS2, to show [ 1 ]…..
Prescaler with Counter by IC digital 4511,74190 Digital frequency counter is being used for wide range of applications. Digital frequency counter extensively uses digital circuits and hence fairly good knowledge of digital circuits and of digital integrated circuits is required to understand the operation of the frequency counter. However a person who is not familiar with any electronics circuits and experiments has in written this article….
PIC16F84A 3.5GHz LCD Frequency Counter room temperature controller with PIC. This equipment uses two temperature sensors, drives external equipment, and keeps the temperature of the room at preset temperature. The purpose of this equipment is for preventing room temperature going up with the heat of the computers. …..
