Setting up an electric guitar is not rocket science, but it is something that a lot of guitarists shy away from. True, if you do this wrong, you can make your guitar play badly, but if you learn to do it right, you could save yourself a lot of cash. I should probably preface this by saying that today we are only going to do a basic setup. This is enough most of the time, but occasionally more is required, such as filing the nut, or doing some fretwork. If you want to set up a tremolo too, go to this post first: Setting Up or Adjusting a Stratocaster Tremolo Also, if you're setting up a Les-Paul-style guitar, you might prefer to have a look at this blog post: http://diystrat.blogspot.com/2012/09/how-to-set-up-gibson-les-paul-style.html So what does a basic setup involve? Let me break it down for you, as follows: 1. Checking and adjusting neck bow (how straight the neck is) 2. Checking and adjusting saddle height 3. Checking and adjusting the intonation (how far back or forward the s...

Switching regulator subsystems intended for use asdc to dc converters. 3V to 40 Volt DC Converter circuit | The use of switching regulators is becoming more pronounced over that of linear regulators because the size reductions in new equipment designs require greater conversion efficiency. Another major advantage of the switching regulator is that it has increasednapplication flexibility of output voltage. The output can be less than, greater than, or of opposite polarity to that of the input voltage. The MC34063 series is a monolithic control circuit containing all the active functions required for dc to dcconverters. This device contains an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active peak current limit circuit, driver, and a high current output switch. This series was specifically designed to be incorporated in step–up, step–down and voltage– inverting converter a...

In this circuit, the LM135’s temperature-dependent output (10 mV/°K) is divided down and applied to A1’s positive input. Temperature To Pulse Width Converter Circuit Diagram: This moves A1’s output high, driving the input to the LM3524’s pulse width modulation circuitry. The LM3524 pulse-width output is clipped by the LM185 reference and integrated by the 1 MW-0.1 µF combination. The DC level across the 0.1 µF capacitor is fed back to A1’s negative input. This feedback path forces the LM3524’s output pulse width to vary in a highly linear fashion according to the potential at A1’s positive input. Here is a schematic drawing: The overall temperature to pulse width scale ...

 This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V (British?) car. The circuit is simple, about 75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages. Notes L1 is a custom inductor wound with about 80 turns of 0.5mm magnet wire around a toroidal core with a 40mm outside diameter. Different values of D3 can be used to get different output voltages from about 0.6V to around 30V. Note that at higher voltages the circuit might not perform as well and may not produce as much current. You may also need to use a larger C3 for higher voltages and/or higher currents. You can use a larger value for C3 to provide better filtering. The circuit will require about 2A from the 6V supply to provide the full 800mA at 12V. 6V to 12V Converter Circuit Diagram Parts R1, R4 2 2.2K 1/4W Resistor R2, R3 2 4.7K 1/4W Resistor R5 1 1K 1/4W Resistor R6 1 1.5K 1/4W Resis...

Power supply circuit to generate output below were variations between 1.3V DC to 12.2V DC with 1A current. In addition, the power supply circuit is also equipped with over-current protection or shield against belebih flow. Power supply circuit is very simple, but the quality is quite good, made her basiskan regulator IC LM723 is a pretty legendary. Description : R2 to set the output voltage. The maximum current is determined by R3, over-current protection circuit inside the LM723 to detect the voltage on R3, if it reaches 0.65 V, the voltage output will be off her. So the current through R3 can not exceed 0.65 / R3 although output short-circuit in his. C3 and C4 are ceramic capacitors, as much as possible directly soldered to the PCB, this is because the LM723 is prone to oscillation that is not cool. LM723 works with 9.5V input voltage to 40 V DC and the LM723 can generate its own current of 150mA when the output voltage is not more than 6-7V under input voltage. Specifications : Ou...

Cheap 12V to 220V Inverter Circuit Diagram . Even though today’s electrical appliances are increasingly often self-powered, especially the portable ones you carry around when camping or holidaying in summer, you do still sometimes need a source of 230 V AC - and while we’re about it, why not at a frequency close to that of the mains? As long as the power required from such a source remains relatively low - here we’ve chosen 30 VA - it’s very easy to build an inverter with simple, cheap components that many electronics hobbyists may even already have. Though it is possible to build a more powerful circuit, the complexity caused by the very heavy currents to be handled on the low-voltage side leads to circuits that would be out of place in this summer issue. Let’s not forget, for example, that just to get a meager 1 amp at 230 VAC, the battery primary side would have to handle more than 20 ADC!. The circuit diagram of our project is easy to follow. A classic 555 timer chip, identified as...

Portable systems often include circuitry that derives power from an external source, such as USB. When the system disconnects from the USB supply, a battery takes over and supplies current via a dc/dc converter. A diode-OR connection (Figure 1 offers the easiest way to ensure that the supply voltage doesn't sag during this switchover to the battery. The diode's forward voltage drop, however, can reduce battery life and efficiency.   A diode-OR connection is effective but lossy.  A boost-converter circuit is an improvement over the simple diode-OR connection. The single-cell, boost-converter circuit with external PFET (Figure 2) is an improvement over the diode-OR connection. The PFET, Q1, coupled with IC1's internal gain block, forms a linear regulator. The USB power supply has a diode-OR connection to Q1's source. Setting the boost converter's output to 3.4V allows the drain of Q1 to regulate to 3.3V. This configuration produces negligible loss in Q1. The bus-suppl...

This Simple Voltage to Frequency Converter Circuits Diagram has a 1 Hz-to-30 MHz output, 150-dB dynamic range, for a 0 to 5 V input. It maintains 0.08% linearity over its entire 71/3 decade range with a full-scale drift of about 20 ppm/°C. To get the additional bandwidth, the fast )FET buffer drives the Schottky TTL Schmitt trigger.  Simple Voltage to Frequency Converter Circuits Diagram The Schottky diode prevents the Schmitt trigger from ever seeing negative voltage at its input. The Schmitt`s input voltage hysteresis provides the limits which the oscillator runs between. The 30-MHz, full-scale output is much faster than the LTC1043 can accept, so the digital divider stages are used to reduce the feedback frequency signal by a factor of 20. The remaining Schmitt sections furnish complementary outputs.
