MERAKI is a responsive environment with live performance. Interactive wires are attached to 4 spatialized speakers and human body capacitance is therefore used to trigger alterations on sound and image. Live guitar, melodica, voice and midi controllers are used to create a sonic atmosphere that floods the space with a large range of sonic impulses.
According to Answers.com, a decade bridge is an: "Electronic apparatus for measurement of unknown values of resistances or capacitances by comparison with known values (bridge).
This one is built into a mahogany (I think) case. The hinges on the lid are broken, so the lid actually comes away from the rest of the case (the catches hold the lid in place, if you're not too rough). Instructions for setting the machine up are printed on the inside of the lid, which also has a bracket for holding a battery pack.
There is some staining on the case (not visible in photos)

This contains all of the math from the Faraday's Ice Bucket video. The work on the right is to calculate the capacitance of the meter and ice bucket by charging a known 33pF capacitor and using this charge to make a conversion between charge and voltage.
The work on the left is to calculate the number of unbalanced electrons on two charged objects
Yes, it's a mouse. It flattens out like this for storage. The gray part snaps down to make a curve for use. The "scroll wheel" is a capacitance strip. It's actually a pretty nice mouse, which is odd for Microsoft.

I bought them at electron market,you'd better go more places to find good quality capacitances,they worth it keeping your machine healthy.

This 3D stereographic photo is of the CardioMEMS device, an implantable pressure sensor that wirelessly measures pulmonary artery pressures without requiring any batteries. It is used for heart failure patients to monitor their hemodynamics and estimate their volume status. This aids in prophylactically adjusting diuretics and heart failure medications before a patient becomes symptomatic and has to present to a hospital for a heart failure exacerbation. Reducing hospitalizations and HF exacerbations would aim to reduce mortality and improve quality of life.
The device is pretty amazing as it is very small and works indefinitely without batteries. The main component is a 15mm x 3.4mm x 2mm rectangle with two nitinol wire loops on each side that extend the length of the device to 4.5cm. Nitinol is a metal alloy of nickel & titanium that exhibits shape memory and superelasticity. Nitinol is commonly used for stents and other medical devices as it is biocompatible and folds up nicely in a tiny catheter before being deployed in the body where it expands to its full size and shape. This anchors the device in the distal pulmonary artery.
Its theory of operation is exceedingly simple in terms of design. It consists of a three dimensional coil of wire and two metal plates on two wafers of fused silica encased in silicone. The coil is produced through electrodeposition of gold onto a silica wafer in a vacuum chamber. Fusion bonding is used to join the silica wafers. The coil of wire forms an inductor and the two metal plates act as a capacitor in physics & electronics terms. This arrangement connected in a parallel loop forms a resonant LC circuit (L=inductance, C=capacitance). Depending on the capacitance and inductance of the components, the circuit will oscillate at a perferred resonant frequency. The capacitor in the CardioMEMS is exposed and very thin allowing the silica crystal and metal plates to deform with changes in pressure from the blood within the pulmonary artery. Changing the distance between metal plates of a capacitor changes its capacitance value thereby changing the devices resonant frequency. An external machine can ping and excite the coil with various electromagnetic radio frequencies until it is able to find its resonant frequency. By working backwards, the measured frequency can be converted into an estimated capacitance which can be correlated to an estimated pressure measurement.
The device is placed during the right heart catheterization (RHC) procedure when the physician threads catheters from a patient's veins through the right atria, past the tricuspid valve, through the right ventricle, and finally past the pulmonary valve into the pulmonary artery. Fluoroscopy or video x-rays along with radiopaque contrast are used to visualize the blood vessels and guide the catheters to their destination. During the RHC, the cardiologist will use a Swan-Ganz catheter to measure the actual pressure and calibrate the device's measured pressures to actual pressures.

A second test, this time on a much larger conductive object (a 20lb piece of metal, to be exact).
Different capacitance range, but it is still very effective at tracking an objects approach, as well as direct touch.
For the protection of antennas, USB 3.0, and HDMI ports from transient voltage signals in portable electronics, Vishay’s new VBUS05L1-DD1-G-08 bidirectional symmetrical single-line ESD protection diode combines an ultra-low capacitance of 0.3 pF with the slim < 0.4-mm profile of the LLP1006 package. (Click ALL SIZES for hi-res version.)
A major issue was the voltage-dropping resistance wire on the full length of the line cord. The heat from the resistance wire destroyed the insulation. I sought advice on this issue and was instructed in how to use capacitance to drop the AC voltage. The copper band was used to bind the resistance wire to the AC conductor.

1,When PCB design, the chip power bypass filter capacitor should be as close to the device as possible, the typical distance is less than 3MM.
2, When draw the PCB, the amplifier input and output signals below the foot and the feedback resistor do not go in other lines, this can reduce the parasitic capacitance between different lines affect each other to make the amplifier more stable.
3, SMT high-frequency devices can be better and also with small size at the same time.
pcb design
4, The circuit board wiring as short as possible while keeping in mind its length and width to minimize parasitic effects.
5, For the power cord processing power cord parasitic characteristics of the worst DC resistance and self-inductance so when the cloth power cord to widen as much as possible.
6, For the amplifier input and output cables above the current is very small so that they are very susceptible to the parasitic effects on them a lot of harm.
7, for more than 1CM signal path is best with controlled impedance and both ends of the termination (matching resistance) transmission line.

In this video, we examine a classic 1840s experiment by Michael Faraday that showed an interesting case of induced charge. We then use the PASCO Faraday's Ice Bucket and Electrometer to measure the charge on an object. This requires understanding capacitance as a conversion factor between electric potential difference and the amount of charge stored. We first find the capacitance of the meter and ice bucket per the PASCO instructions, and then we measure the charge on a sphere that has been charged with a Wimshurst machine and later simply by rubbing two cloths together. This revision to fix an error in scientific notation I made
