Visual metronome - The Metronome is any device that produces a regulated audible and/or visual pulse, usually used to establish a steady beat, or tempo, measured in beats-per-minute (BPM) for the performance of musical compositions. It is an invaluable practice tool for musicians that goes back hundreds of years

Vox AC30 Guitar Amplifier Simulator - This project has been withdrawn at Stephan's request, as he has sold the rights for the AC30 Simulator to a manufacturer. While its removal is obviously a loss for my site, I wish him well. Sorry for any inconvenience. __ Designed by Rod Elliott ESP
Vox AC-30 Top Boost adapted for use as a distortion stompbox - The Vox AC-30 amp is considered by many to be the defining sound of the British Invasion during the 1960s. The Top Boost circuitry provided crisp treble-laden overdrive that perfectly complemented the rich bass content. The English Channel is a JFET-based distortion stompbox that uses the same basic architecture as that classic early '60s amp. __ Contact: holler @ runoffgroove.Com
Wave Multiplier for music synthesizers - The idea for this project came from the fabled middle section of the Serge wave multipliers. At the time I designed this, I had never seen or heard one of these units, nor had I seen its schematic diagrams, but armed with descriptions and suppositions by various people who had seen them, and a couple of photos of CRO traces from the output of the module, I decided to design myself one. __ Designed by Ken Stone
Why do we need Mixer? - Article: The mixing of a number of audio signals is such a common thing to do that one would expect the Net to be riddled with articles on how and why signals are mixed. There are plenty of circuits that show how it can be done, but very little that explains the benefits or drawbacks of any particular scheme. __ Designed by Rod Elliott ESP
Wide Band Zero Cross Detector - This circuit was designed to convert a low amplitude 40KHz signal into a clean square wave signal. It will work with inputs as small as 5mv peak-to-peak or as large as 3 volts peak to peak. The input frequency can range from a few kilohertz to about 150. . . Circuit by Dave Johnson P.E.-February, 2006
Wide Bandwidth Photodiode Amplifier - Wide bandwidth performance from a small photodiode requires minimizing the total input capacitance. In this circuit the amplifier's differential input capacitance is bootstrapped by the feedback with R1 and R2. Choosing the amplifier input that is at the corner of the package for the dual LTC6244 also minimizes pin-to-pin capacitance. __ Linear Technology/Analog Devices App Note, Mar 16th 2010
Wideband AGC has 60-dB dynamic input rang - 10/10/96 EDN-Design Ideas Automatic-gain-control(AGC] circuits serve in many applications to maintain signals at fixed levels. However, in applications such as digital-receiver circuits and back-channel modems, the function of the AGC often aims more at increasing dynamic input range through the controlled application of both gain and attenuation. In this type of application, the AGC is usually upstream of a high-speed ADC. The Design by Carl Dickey, National Semiconductor, Comlinear Division
Wideband Low Noise Amplifier Drives 50 Ohm Loads - 10/23/97 EDN-Design Ideas The circuit in Figure 1 is a wideband, high-gain amplifier with two useful features not often found in combination The input-referred noise is 2.6 nV/(square root Hz], yet it can deliver 27 dBm into a double-terminated 50 ohm load or 30 dBm into a single-terminated load. The circuit uses two monolithic op amps Design by Mitchell Lee, Linear Technology Corp, Milpitas, CA

Wideband Oxygen Sensor Controller Mk.2, Pt.2 - Last month, we introduced our new Wideband Oxygen Sensor Controller Mk.2 and described the circuit. This month, we give the circuit for the display unit and the full construction details. __ SiliconChip
Wideband peak Detector operates over wide input-frequency range - 11/22/07 EDN-Design Ideas An ultrafast comparator and associated circuitry enable peak detection over a wide input-frequency and -voltage range Design by Jim McLucas, Longmont, CO
Wideband Receiver - The LTC5551 is a 2.5V to 3.6V mixer optimized for RF downconverting mixer applications that require very high dynamic range. The LTC5551 covers the 300MHz to 3.5GHz RF Frequency range with LO frequency range of 200MHz to 3.5GHz. The LTC5551 provides very high IIP3 and P1dB with low power consumption. A typical application is __ Linear Technology/Analog Devices App Note, Sep 19th 2013
Wideband VHF/UHF/SHF 22dB RF preamp with MAR-6 or MAR-8 (MSA-0885) - The MAR6 (MSA-0686, 0685, 0885) is a high performance silicon bipolar Monolithic Microwave Integrated Circuit (MMIC) housed in a low cost, surface mount plastic package.
This MMIC is designed for use as a general purpose 50 W gain block. Applications include narrow and broad band IF and RF amplifiers in commercial and industrial applications. __ Designed by Guy Roels ON6MU
Wideband, High Input Impedance, Gain = 1000 Amplifi er - The gain is distributed equally between four amplifier sections in cascade, so the gain of each section is about 5.6. Distributing the gain uniformly provides the best bandwidth. Trimming of the final stage corrects for resistor variances so that overall gain is 1000x. __ Linear Technology/Analog Devices App Note, Jun 21, 2011

Wien-bridge Theremin - This circuit is a basic theremin with only a pitch control. It uses the "heterodyne" technique, as did Theremin's original instrument. Heterodyning is advantageous in its simplicity, and is made further attractive in this Design by eliminating the coils that are usually hard to find (electronic design 10/05) __ Designed by Arthur Harrison

Wurlitzer Jukebox repaired with digital MP3/WAV file player & auduino - This cool old jukebox from Wurlitzer is owned by my dad, its 100% all mecanic brain from 1965 is worn out many years ago,
it is very complicated and time consuming to make it run stable for just a few days before a new problem show up,
So the perfect fix is to skip the mecanics, use all buttons and credit indicator as it is, and make it all digital, __ Designed by Thomas Scherrer OZ2CPU
Yet Another Mobile MP3 Player - This is an earlier player using a conventional PC motherboard, so the power supply I designed is quite compatible. __ Designed by Bob Blick
YPBPR to RGB Converter - In this realization of a component video (YPBPR) to RGB adapter, amplifier count is minimized by performing passive arithmetic at the outputs, but this requires higher gains, thus a higher supply potential is needed for this (for at least the positive rail). One small drawback to this otherwise compact solution is that the __ Linear Technology/Analog Devices App Note, Mar 25th 2010

Zonk Machine & Treble Booster - Thanks to A. Coleman for lending his original Hornby-Skewes Zonk Machine for tracing. This is another of those obscure distortions that were designed in the early years of electronic distortion for guitars. It’s not YAFF (Yet Another Fuzz Face) circuit, and it’s probably more interesting for that. Thanks also to “amscray” for providing the schemo for the Hornby-Skewes Treble Booster, which is purportedly the preferred front end for this __ Designed by R.G. Keen |
