- Draft — Purple alert — Preculsions are left hanging in this developing experimental flash that happened while attempting to document other hot flashes. Your need-to-know pulls you toward The Button
is a term found in a 1990 NIST report Stochastic Properties of Trichel-pulse Corona:... (see below).
- The developer's First exposure to an Arduino began a compulsive adventure to examine the nature of the electrical noise in an open A/D converter input of the Arduino processor board. I.e., Arduino does space charge. Tune in here The Button
- Looking at multiple channels of various low-frequency components in the noise, drawn by the script-o-meter on the computer screen, showed marked summing-amplification of low frequency components in the noise. The visual channels were created in a simple Processing Language script that received COM port data of the amplitude of each N-recent averages from the Arduino.
- Especially after the room with a running N-recent-average — O — scope that had been vacant for a period,
- The low registers of the Processing Language script-o-scope channels showed a ten-to-one summing-amplification above the noise-floor signal amplitudes when observer #1 entered the room (me).

Ponder Trichel-pulse-train memory
- The Trichel pulse is a plasma discharge that doesn't continue, for lack of energy. The aborted-arc occurs from a needle point with a negative high-voltage charge (~ 2kV). The point is perpendicular (normal) to an electrically grounded flat metal surface.
- The first pulse takes a bit higher voltage to initiate than any subsequent pulse in the same test. Substantial research has established that a residual ion charge is in the air surrounding the pulse that influences subsequent pulse thresholds.
- Air ions from pulses affect pulse rate. Very natural.
- This test may also serve as a sensorization of air, in some more refined device, to serve as another dimension of analysis (a QAT–ish approach) in the memory-effect observed with human activity around an open A/D channel on an Arduino (Debunking Hodowanec). That effect 'disturbed' future readings, as if the effect diminished into the noise floor, from when it is first observed. The Developer was not harmed during observation of VLF from proximal human motion.
Ponder Geiger Counter recovery time-out
- The Geiger Counter device, counting radiation particles, is detecting ionization of gas. The detecting gas becomes over exposed, so to speak. A recovery period is necessary.
- Thinking this through again...

Damn the legal department! Full disclosure ahead!
- The rational explanation seems to be that air ions will stratify air into valence strata, per se.
- Normal human pipe-dream propensity entails that a 2D sensor-grid of end-points of shielded wires to an array of Arduino A/D input pins could plot data over time of the motion dynamics of the ion charge felt by each sensor point.
- But, connect thousands of grid-point sensors on a 3D matrix and burn through a large grant.
Don't miss Debunking Hodowanec ...
...for the how-to of time-period-selective summing-amplification.
The Developer ain't no computer scientist. Think boomer boy-scientist on a personal quest with an esoteric skill set.
