Mac OS X Mountain Lion review

In the tale of two operating systems, Apple's Mountain Lion is a less ambitious endeavor. Rather than completely rewriting the book as Microsoft is attempting with Windows 8, Apple's latest operating system simply cleans house, clearing clutter, while bringing more cloud and sharing features into the fold -- specifically to make the desktop play nice with iOS devices. Some of the new features come directly from iOS, and many are welcome, but some seem unnecessary. Ultimately, what you get is the familiar layout of Apple's operating system and much less of a learning curve than with what we've seen so far of Windows 8's completely new touch-screen-focused interface. The Mountain Lion release marks the second time Apple has offered an incremental...

Medium power FM transmitter circuit

Description. This is the circuit diagram of a moderate power FM transmitter circuit employing two transistors.The voice signals picked by the microphone will be amplified by the transistor Q1.The second transistor is wired as an oscillator operating in the FM band.The output of T1 is given to the base of T2.T2 performs the modulation also.The tank circuit comprising of components L1 and C6 determines the frequency of the signal, and can be varied by adjusting C6.The capacitor C7 couples the FM signal to the antenna. Circuit diagram with Parts list. Notes. You can assemble the circuit on a general purpose PCB.  The circuit can be powered from a9V PP3 battery. The Antenna A1 can be a 1M long wire. The inductor L1 can be made by...

1000W Inverter circuit and kit

This power inverter circuit will provide a very stable Output Voltage.Frequency of operation is determined by a pot and is normally set to 60 Hz. Various “off the shelf” transformers can be used. Or Custom wind your own for best results. Additional MosFets can be paralleled for higher power. It is recommended to Have a “Fuse” in the Power Line and to always have a “Load connected”, while power is being applied. The Fuse should be rated at 32 volts and should be aproximately 10 Amps per 100 watts of output. The Power leads must be heavy enough wire to handle this High Current Draw! appropriate Heat Sinks Should be used on the RFP50N06 Fets. These Fets are rated at 50 Amps and 60 Volts. Other types of Mosfets can be substituted if you wish. At...

250W PWM Inverter Circuit SG3524

A 250W PWM inverter circuit built around IC SG3524 is shown here. SG3524 is an integrated switching regulator circuit that has all essential circuitry required for making a switching regulator in single ended or push-pull mode. The built in circuitries inside the SG3524 include pulse width modulator, oscillator, voltage reference, error amplifier, overload protection circuit, output drivers etc. SG3524 forms the heart of this PWM inverter circuit which can correct its output voltage against the variations in the output load. In a non PWM inverter the change in output load directly affects the output voltage (when output load increases output voltage decreases and vice versa), but in a PWM inverter the output voltage remains constant over a...
