Don't go without one. It's worth it if all you use it for is testing for continuity when checking your work.
So this thing is pretty awesome. I remember reading somewhere that he was trying to combine a Fuzz Face with a pre-boost circuit of some kind. Like a Rangemaster feeding a Fuzz Face (or vice-versa). Anyway, it didn't turn out like he'd planned, but he liked what it did.
The "Body" control alters the input capacitance. As you bring in more capacitance, the circuit changes the way it behaves. The, "Bright" control changes the high-frequency response in a similar way and has kind of a tipping point, as well.
It's got an input impedance control so it will work with humbuckers. The other two pots are just Fuzz and Volume.
Obviously the hippest thing is that it responds to your guitar's Volume pot in a way very similar to a regular Fuzz Face. It's got a lot of different tones on-tap. This is a very nice fuzz circuit.
I didn't realise it at the time I took this photo, but the HT circuitry had gone u/s. The PA voltage was low and very "ripply".
All high voltage electrolytic capacitors were subsequently replaced, and as suspected one of the two main HT reservoir capacitors was found to be completely dud when tested during the replacement process.
All the others appeared to be in reasonable condition though some of them read on the high side on my capacitance meter which is sometimes regarded as a sign that the component is getting to the point where it needs to be replaced. I'm not 100% convinced one way or the other, but all electrolytic capacitors in the high voltage sections (HT, Screen, Driver and Bias) were replaced anyway, as a precaution.
The CED isn't in good condition. The best focus area is the lower left corner.

The CED isn't in good condition. The best focus area is the center to the left hand side. You are looking at it the direction the needle would read it, from bottom to top (or vice versa, I don't know if the disc travelled clockwise or counter-clockwise).

Much better results with the capacitor to the left, as opposed to the big microwave oven capacitor, when used on the trigger coil primary circuit. The smaller one is 1/3 the capacitance of the larger. The inductance of the smaller capacitor, as Dr. Lindsay Wilson recently pointed out, is much lower by virtue of it's internal design.

INTRODUCTION
Many manufacturers and users of precision electronic
equipment suffer needlessly from unexplained instabilities
and drifts due to noise effects. They resign themselves to
making constant adjustments and troubleshooting. But in
fact these can be avoided. Instability is often traceable to a
few supposedly “fixed” resistors which are not really fixed at
all. If these resistors would only retain their original values,
there would be no need for costly controls and other
compensating circuitry. That’s why the only resistor for
applications such as these is Vishay Bulk Metal® Foil. In
high-end audio equipment, careful selection of resistors is
one of the best ways to avoid or minimize noise and
distortion in the signal path. Noise is an unwanted wide
spectrum signal that may be superimposed on any useful
signal, including DC. Resistors, like other passive
components, are noise sources to various degrees,
depending upon resistance value, temperature, applied
voltage, and resistor type. Many experiments have been
done to show why some resistors are “noisier” than others.
But the only test that audio experts and audiophiles have
agreed on is comparing the level of fidelity that results when
different resistor technologies are used in actual audio
systems.
High-end analog audio applications require low intrinsic
noise, high linearity of amplification, and minimal dynamic
distortion. The typical audio amplifier consists of a voltage
preamplifier (preamp) and power amplifier (final driver). The
voltage preamplifier deals with low-level signals. That is why
its intrinsic noise level is critical. Resistors are among the
principal noise sources in the amplifiers. The main
requirements for the audio power amplifier are high linearity
of amplification and minimal dynamic distortion. Vishay Foil
resistors are characterized by very low intrinsic non-linearity
of the resistive element, which is made from cold-rolled bulk
metal.
The VAR, composed of Vishay’s Bulk Metal® Z-foil
technology, with improved sound quality, provides a
combination of low noise and low inductance/capacitance,
making it unrivalled for applications requiring low noise and
distortion-free properties.

THEREMIN: strumento elettronico / dal sito di Mr. Popescu www.benedict-popescu.ro
Question 1: Is this instrument your invention ?
Answer 1: It is quite an old idea, belonging to the Russian Lev Sergeivitch Termen (Anglicised to Leon Theremin). He invented the instrument immediately after the first world war (in 1919 actually) while a student at the University of Petrograd. At that time electronics was still very close to its beginnings. Theremin’s invention was, in fact, the first synthesis of an acoustic sound using electronic circuits. That’s why Leon Theremin is now recognised as being the parent of other electronic musical instruments (analog and digital synthesisers). As you probably realise, the instrument is not my invention, but it is 100% my own design (see the explanations concerning my style of play – the Answer to Question 10).
Question 2: What is the name of this instrument ?
Answer 2: It is called theremin, coming from the name of its inventor. The instrument was initially called the ‘aetherphone’, then the ‘thereminvox’ and finally it received the name of its inventor.
Question 3: How does it work ?
Answer 3: The theremin is based on the ‘beat frequency oscillator principle’ or heterodyne effect. The audio signal arises from the difference between relatively high frequencies of two oscillators - one having a fixed frequency and the other one a variable frequency. The variation of the oscillation frequency for the second oscillator is determined by the variation in capacitance of only a few picofarads between an antenna and the player’s hand. Two such pairs of oscillators are used in each theremin: one is to control the pitch and the other one is to control the volume. The player uses his (or her) hands to control simultaneously the pitch and the volume.
Question 4: Is the theremin sensitive to any body or hands movements around it ?
Answer 4: Yes. The theremin ‘feels’ the presence of any body, hands or even fingers (not only of the player, but of any other person or animal!) moving in its proximity.
Question 5: Is it difficult to play the theremin ?
Answer 5: Yes. The theremin is, in my opinion, the most difficult instrument to play. One difficulty comes from the fact that the performers have to move their hands in real time (sometimes with the precision of a millimetre or even less), the only control being the results of these movements. Another difficulty comes from the fact that, when the performer has to play higher and higher notes, the ‘spacing’ (or distance between hand positions in space corresponding to successive notes) becomes smaller and smaller, thus making the intonation of achieved notes less and less accurate.
Question 6: Does the player touch the theremin while performing ?
Answer 6: No, not at all. The player only touches the knobs for tuning the instrument before performance, but not during playing. The theremin is unique in that it is played without there being any physical contact whatsoever between the performer and the instrument. Therefore the theremin performer plays without the benefit of any tactile reference. Unlike, say, a violinist, who is in continuous contact with the instrument’s fingerboard, the thereminist feels no shape or force when moving from one pitch (or volume) to another. The performer is constantly moving his or her hands, listening carefully to how the resulting sound changes, and then intuitively ‘trimming’ the precise position of the hands to get the desired pitch and volume. The process is one of continuous feedback. Notably playing the theremin can produce music of great expressiveness. The player leaves his personal mark on the rendition.
Question 7: Does everyone have chances to become a good thereminist ?
Answer 7: Unfortunately not. There is a minimum of conditions without which it does not merit to try: you must have a perfect ear for music and a very precise control of hand motions.
Question 8: Anything else?
Answer 8: Yes. Practice, practice and again practice until you will be able to move in real time your hands for faster and faster melodies in order to play them with correct intonation. Even more practice (years and years) will be required until you can play with feeling (to be capable of transmitting a sentiment from your heart to the heart of those in your audience).
Question 9: Are there different styles in playing the theremin ?
Answer 9: Yes. First of all, as for any other instrument, there are right and left handed players. But not only this. Most people play the theremin in the 'classical' style. For the classical theremin the pitch antenna is placed vertically in the right hand corner of a wooden or otherwise non-conducting cabinet. The volume antenna, usually shaped as a loop, is normally placed horizontally on the left hand side of the cabinet. The player changes the pitch of the sound by moving the right hand in a horizontal plane near the pitch antenna. The closer the hand is to the antenna, the higher the pitch of the generated sound. The player controls the loudness of the sound by moving the left hand in a vertical plane near the volume antenna. When the hand is close to the antenna the instrument is silent and maximum volume is obtained when the hand is moved away from the antenna. As you will see below, in playing the theremin I use my skills as a musical saw player and I have my own style, which I believe is unique in the world.
Question 10: Is it important how you place in space the pitch and the volume antennae ?
Answer 10: No. In order to avoid the interference between the two antennae you must place them in perpendicular planes. What is different in my style of play is the fact that I have changed the configuration in space for the pitch and volume antennae in comparison with the 'classical' style. For my theremin I use two pitch antennae, placed in horizontal planes, of the same length but different thicknesses. This arrangement allows me to improve the ‘spacing’. In order to control the pitch I can play low notes by bringing my left hand from my body nearer to the lower antenna, and higher and higher notes by moving my hand from the low to the high antenna. The way of controlling the volume is inverted when compared with the ‘classical’ style. The volume antenna looks like a simple plate - placed in the vertical plane. When my right hand is away from the plate the theremin is silent and the volume increases to the maximum when my right hand is moved closer, to within two inches of the plate.
Question 11: What about the tone produced by the theremin ?
Answer 11: The tone of the theremin depends on the instrument model used. Some people prefer the tone of theremin made by RCA (Radio Corporation of America) in the nineteen-thirties using electronic tubes. The tone of this model is close to that of a violin. Some other people like rather a smooth ethereal tone. I personally prefer the second one which is likened to that of a musical saw.
Question 12: Is it possible to use the theremin to create sounds other than that of the theremin itself ?
Answer 12: Yes. You can interface your theremin with other (digital) sources of sounds (sound modules, samplers, computers, etc.) using a MIDI (Musical Instrument Digital Interface) and command with your theremin these devices to generate sounds of a large timbral variety. The only requirement is to own a fast and accurate enough MIDI device.
The Aquafina brand name and logo are briefly visible on the water bottle in front of Sheldon. This is likely not a deliberate product placement for Aquafina because the brand name appears rather tiny and the occurrence was really short.
Hylozoic Soil is an interactive geo-textile mesh that senses human occupants and responds with air movement. Machine intelligence is embedded within networks of micro-controllers that coordinate arrays of capacitance and proximity sensors. Kinetic actuators are used to create a diffuse peristaltic pumping that pulls air and organic matter through the occupied space. The primitive cycles of opening, clamping, filtering and digesting in the artificial assembly are affected by some of the same natural forces that make a coral reef work. Building upon simple motions embedded within individual elements, accumulated actions produce turbulent wave-like reactions.

Here's the external face of the aft inboard rib on the left fuel tank, now riveted to the skin. You can also see that the Aircraft Extras Fuel Guardian has been installed, as has the Princeton Capacitance Fuel Probe.
The next piece to put in place will be the aft baffle, connecting the back flanges of all of the ribs and closing off the tank. However, before this happens, I'm going to have my EAA technical advisor come and have a look at the innards to make sure I'm not missing anything.
Low pressure nitrogen laser powered by output from an unrectified, 8kV, 60 Hz, AC sign transformer. Although the transformer output is AC, the dumper capacitor is quite small in terms of actual energy storage. As a result of this low capacitance and the relatively low frequency of the output from the high voltage power supply, the dumper is able to charge and discharge between peaks in the alternating current. If the current supply was too small, or the capacitance and frequency too large, this technique would not work without having the current supply rectified.
The original peaker and dumper capacitors were metal plates (sheet metal and aluminum tape) seperated by a plastic "for sale" sign. During operation a hole was burned through the plastic on the peaker, so I replaced the peaker with a Leyden Jar. The Leyden Jar is made from an empty "Smart Balance" brand "Buttery Spread" container.

This project is part of the Ars Electronica Garden Auckland, Aotearoa.
The Radarmin is an experimental musical interface that uses the Google Soli as a means to control a musical track in real-time. It enables the user to “play” a virtual musical instrument, and is intended as a demonstration of the capabilities of emerging touch-less interaction interfaces to facilitate new means of musical expressions. The Radarmin uses a touch-less interaction technique made popular by a unique musical instrument developed in the 1920s, the Theremin. While the Theremin works on the principle of change in capacitance, the Soli is a millimetre wave radar that works on the Doppler shifts it detects when objects are moved around it. This project is an attempt to showcase the abilities of the Soli as a creative, musical/auditory interface.

As much as 20% to 60% of the energy used to operate compressed air systems is wasted! One of the major contributors to this waste is operating air systems at elevated pressures.
Well known is the fact that compressed air, stored at higher pressures, can provide a capacitance effect for sudden hign volume demands. Less known is that higher pressure storage, that is not properly controlled and managed, will result in not just the additional energy to compress to a higher pressure, but also significantly higher air consumption from all compressed air users!
Ingersoll Rand flow and pressure controllers have been developed to optimize systems in order to eliminate waste by efficiently and effectively managing system storage through flow and pressure control.

This is a Magnetek 24uF 400VAC capacitor that has been from its metal can. I have another picture of it in the can before it was removed. The can is filled with oil before it is sealed. It is however fragile without the protection provided by the can.
The construction is fairly simple. Basically it's 2 sheets of foil and 2 sheets of plastic rolled up on a core. The foil sheets are arranged so that one goes off the edge of the plastic on either side. The sides become the ends of the capacitor (left and right in the picture). Then some conductive (contains metal flakes) glue or epoxy is pasted on the ends. This helps lower the inductance and ESR by connecting the long spiral of thin foil together with itself.
Normally the capacitor is submerged in oil. The oil is mainly for cooling purposes and isn't even needed under low stress conditions. The oil in this one was about as thick as engine oil and smelled like a wheat snack I ate once.

"This is one of the most accurate and simplest LC inductance / capacitance Meters that one can find, yet one that you can easily build yourself.
This LC Meter allows to measure incredibly small inductances starting from 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from 0.1pF up to 900nF.
LC Meter's circuit uses an auto ranging system so that way you do not need to spend time selecting ranges manually. Another neat function is reset switch that will reset the initial inductance / capacitance, making sure that the final readings of the LC Meter are as accurate as possible."
