GroupKOS Developer Share wiki is here to share my past and re-emergent project space with you, from feed and care for a MediaWiki, to re-creating spy-code algorithms in VB6.

A Hexatronic style prototype electronic sculpture, the Flicker mapper, mapping the 1/f drift in local space timing.

A fiber-optic bundle connects into a dangling chain of divide-by-2 LEDs flashing, slower toward bottom.

The fiber data goes away to a data-logger for study of frequency drift anomalies known as flicker, or the 1/f frequency drift.

This study is inspired by an experiment to map the ambient dielectric potential in the space above a computer desk, using an open-input of an Arduino A/D pin.

A digital comb filter was implemented in the Arduino C code as a running average of a recent window of samples. The windows sizes and filtered-results of a running-stream of A/D readings sent to a COM port were visualized on a desktop PC using the Processing language to code a data-stream receiver, and output a running 'oscilloscopic view' of the running average of the recent-average sampling window.

A similar sampling study of a drift anomaly in the magnetic domain with a Hexatron magnetic vortex sculpture will help correlate the static-flux testing described above with the 1/f drift anomalies in the magnetic domain.

Frequency-drift readings of a chaotic ring oscillator is implemented in a hexatronic design 3-phase torus knot. Ambient influences upon a rotary-resonant knot (think donut with spiral wings) will tend to be imprinted within an apparently chaotic filter of no certain time-base regularity. I.e., the ambient influence on the magnetic domain is lost beneath the amplitude of the noise.

A one megaHz operating frequency standing-magnetic-resonant copper loop is the target scale's natural frequency for self-resonance brought upon by high-frequency current spikes. The current spikes are milliamps, and delivered by very small integrated circuits soldered directly into the sculpture.

The noise component is accumulated timing error normal in the operation of an asynchronous ring oscillator (non-clocked, self-clocked). While desktop static flux (air ions) were very sensitively sensorized (akin to frog-ear-hair audio-amplification via ionic-sonic pumping the hair root to resonance) I doubt the static-power range will correlate with the milliamp power range of the magnetic harmonic elements. The test is important also as an exercise of the sensorization of randomness.

However, the frog-hair sensitivity of recent-window-running-average (RWRA) to dynamics beneath the magnetic noise floor is fascinating. Especially fascinating is the potential harmonic coupling of the 1/f with the Earth/Moon magnetic environ always locally subdominant.

Based on how the TTL logic-signal level noise-sniffer above behaves, the next variety will break-out the TTL totem pole used as the ring
