Simple Cell Phone Jammer Wiring diagram Schematic 2
A beautiful diy gsm jammer or mobile cell phone jammer schematic diagram for use only in GSM1900 with frequency from 1930 MHz to 1990 MHz. The GSM1900 mobile phone network is used by USA, Canada and most of the countries in South America.
This cell phone jammier is not applicable for use in Europe, Middle East, nor Asia. The GSM jammier schema could block mobile phone signals which works on GSM1900 band, also called DCS. For more cell phone jammers check the related posts.

2 Transistor Electronic Siren Wiring diagram Schematic
This is the electronic siren schematic diagram which used 2 transistor BC547 and BC557. The siren is powered by 9V battery or power supply adapter and use 8 ohm speaker to produce the sound. The siren is controlled by the touch plate switch. If you touch the plate, then this electronic siren will be activated.

2 X 40 Watt STK amplifier
Components of the above is one component of ic which is applied as a reinforcement. Power amplifier used in an audio signal in order to become more powerful and can be heard via a tool that is the speaker. But in each set must have a voice amplifier, voltage, power quality is different.
For the IC has the output power above 2 X 40 Watt with 8 Ohm output impedance. Supply voltage ranging from 18 Volt to 32 Volt.

Build an Audio notch filter 2
Build an Audio notch filter 2 Circuit Diagram. With the schema shown here the response at one octave off tune is within 10% of the far out response: notch sharpness may be increased or reduced by reducing or increasing.respectively the 68 ohm resistor. Linearity tracking of R8 and R9 has no effect on notch depth. The signals at HP and LP are always in antiphase, notch will always be very deep at the tuned frequency, despite tolerance variations in R6-9 and C2, C3.

Power Supply 1 2 12V 1A with low voltage LED Indicator
This power supply can provide output voltage 1.2V - 12 with maximal output current is 1A, low voltage LED indicator added in this schematic diagram. The indicator part includes three diodes and one LED. For example you are charging a battery, you can observe the charge status at that moment. Another advantage of this schema, when the drawn current exceeds 1A (practically 0.85A), the current protector in LM317 intervenes and LED indicator warns you about the very low output voltage.
