Removable flash memory sticks are pretty much one of the most handy little pieces of technology to come along in the last couple of years. They come in various shapes and their storage size can range from a measly 128 MB to a whopping 32 GB. So I thought, with the speed of flash drives today, it could be possible to install Windows XP onto those PCs in a much faster time than with optical media (CD/DVD). Plus with all the motherboards I use, I always make sure that the motherboards support booting from USB as it’s a very handy feature. Requirements: A copy of Windows XP Home or XP Professional. USB memory stick (2 GB recommended - 1 GB minimum) A motherboard that is capable of booting from a USB drive (check your motherboard manual if not sure). Most computers have this option.

Improve Solar PV Panel Efficiency and Output Power There are a number of means available to increase solar panel output and efficiency — some of which may be utilized by the serious experimenter. These are listed as follows: Solar Cell Technology There are a number of technologies being researched and there are continual advancements. Experimental technologies and highest efficiencies include: Multi-cell gallium arsenide – 44% Single cell gallium arsenide – 29% Crystalline silicon - 25% Thin film copper-indium-gallium-selenide – 20% Emerging PV technologies (dye-sensitive cells etc.) – 11% (low efficiency, but very inexpensive) Check out this link for an informative solar cell research chart: http://upload.wikimedia.org/wikipedia/commons/7/71/PVeff%28rev121211%29.jpg Unfortunately, we live in the real world and the highest efficiency technologies are either unaffordable or have not been put into production. As a result, the experimenter is generally stuck with crystalline silicon techn...

                                    Powered with solar panel, the circuit will give you 5V pure regulated DC voltage. The circuit is made up of an oscillator transistor as well as a regulator transistor. The solar panel charges the battery when sunlight is bright enough to generate a voltage above 1.9v. A diode is necessary between the panel and also the battery as it leaks about 1mA from the battery when it really is not illuminated. The regulator transistor is intended to limit the output voltage to 5v. This voltage will likely be maintained over the capability of the circuit, which is about 10mA. The oscillator transistor should be a high-current sort as is is turned on for a extremely limited time period to saturate the core of the transformer. This energy is then released as a high-voltage pulse. These pulses are ...

This is the power inverter circuit based MOSFET RFP50N06. The inverter capable to handle loads up to 1000W, it’s depended on your power inverter transformer. The RFP50N06 Fets are rated at 50 Amps and 60 Volts. Heatsink is required for cooling the MOSFETs. You may add some MOSFETs with parallel connection to get more power. It is recommended to have a “Fuse” in the Power Line and to always have a “Load connected”, while power is being applied.  Simple 1000W Power Inverter circuit diagram

This is a Simple IC 555 Timer Tester Circuit Diagram . This simple and easy-to-use gadget not only tests the IC 555 timer in all its basic configurations but also tests the functionality of each pin of the timer. Once a timer is declared fit by this gadget, it will function satisfactorily in whatever mode or configuration you may try it. The two basic configurations in which a timer IC 555 can be used are the astable and the monostable modes of operation.  When the DPDT switch (S2) is in position 1-1, the timer under test automatically gets wired as a monostable multivibrator. In this case, the monoshot can be triggered by the microswitch (S1). The debouncing circuit constituted by the two NAND gates of IC1 (N1 and N2) produces a clean rectangular pulse when the microswitch is pressed. Resistor R3, capacitor C1 and diode D1 ensure that the trigger terminal of timer IC 555 (pin 2 is the trigger terminal) gets the desired positive-to-ground trigger pulse. This differentiator circuit...

The RF sweep frequency generator (‘wobbu-lator’) published in the October 2008 issue of Elektor has a receiver option that allows the instrument to be used as a direct conversion receiver. This receiver does however have a noise floor of only –80 dBm, which really should have been –-107 dBm to obtain a sensitivity of 1 µV. So, for a good receiver sommore gain is required. A wideband amplifie however, generates a lot of additional noisas well and as a consequence will not resuin much of an improvement.  As an experiment, the author developed a selective receiver with a bandwidth of about 4 MHz. Because a gain of at least 35 dB is required, the preamplifier consists of two amplifying elements. The input amplifier is designed around a dual gate MOSFET, type BF982. This component produces relatively little noise but pro-vides a lot of gain. The output stage uses a BFR91A for some additional gain. Preamplifiers where both the gate and the drain are tuned often struggle with feedback via the...

Classic Tone Control Circuit with Low Noise Transistor Tone control is a type of equalization used to make specific pitches or “frequencies” in an audio signal softer or louder. A tone control circuit is an electronic circuit that consists of a network of filters which modify the signal before it is fed to speakers, headphones or recording devices by way of an amplifier. Tone control allows listeners to adjust sound to their liking. It also enables them to compensate for recording deficiencies, hearing impairments, room acoustics or shortcomings with playback equipment. For example, older people with hearing problems may want to increase the loudness of high pitch sounds they have difficulty hearing. Tone control is also used to adjust an audio signal during recording. For instance, if the acoustics of the recording site cause it to absorb some frequencies more than others, tone control can be used to amplify or “boost” the frequencies the room dampens. This classic tone control circui...
