Transistor switched moving magnet movement.
Pendulum wall clock, Japanese made Seiko. This is one of my fav. It has an unusual shape pendulum. The working principle of this clock is very interesting. It was made during the brief age of the transistorised technology. There is an electronic circuit which provide constant impulse to the pendulum. The swinging pendulum, coupled to the mechanical movement would then drives the gear mechanism to provide accurate time indication. One unit of 2SB75 PNP transistor is used for switching on/off of the circuitry necessary for the electromagnetic interaction which help to keep the pendulum in motion. There is a minute length of permanent magnet embeded in each end of the curve shape rod pendulum. Each end of the rod is design to move thru the coils placed at opposite end as the pendulum goes thru its motion. As the rod begin to enter the coil(trigger coil) on the left during the right to left transition, an electromagnetic pulse is generated in the coil which in turn triggers on the transistor circuit. The transistor would then amplify and conduct a current thru the impulse coil on the right. As the pendulum reverse its motion and begin to move to the right, the impulse coil attracts the rod and pull it towards it, at this moment, the rod moves out of the trigger coil and the transistor is turn off and the rod would then reverse its direction, the cycle repeats itself and keep the pendulum in motion.
Sorry for the lengthly explanation, it is a bit tricky to explain. This design was short lived and soon went out of favour as the cheaper and much more accurate & reliable quartz technology came along in the 80's.
There is one peculiar thing about the battery compartment that puzzled me for a long time. I was wondering why there is a dual battery configuration. While one pair of wires is connected to the circuitry, there is none connected to the other battery. It was then that I realized that there was a chiming mechanism originally installed and was subsequently removed. The other battery was supposed to run the chime instead. This clock was made in the early 1960's.
Only Time will tell and every clock tells a story....
The problem with clock is, once you got two they start to multiply..
It all started when I acquired my first clock a 1960's jap 7-day wall clock from a colleague of mine by the name of Wong Mun Lai, a clock collector

It was a non-working clock which I wanted to hang up for display. After a while, I felt something amiss. A clock is not a clock if it does'nt work! So I took it apart and do some fixing, to my surprise I managed to get it ticking again ! I was totally fascinated From there I got my second, third and so on....
My favourite has to be the 400 day clock
Amazing time piece and fun to repair Next in line is those of the electromechanical design type
I love the working principles
At the time of writing, my collection is still growing....but has grind to a halt as my interest is now focus on nature photography

Intense Auroral band with reflection, photographed near Haines Junction, Yukon Territory around 2 AM on April 19.
I've always been (and still am ) admiringly envious of those lucky Aurora photographers who live near large bodies of water in the Auroral zone. On Flickr, you can see the most breathtaking shots of Auroras reflecting on bays or inlets, especially from Scandinavia. Such shots are difficult to catch around here .... Basically, when it's dark here, everything is normally frozen ... Conversely, when it's warm enough for things to remain unfrozen we have 24 hour daylight. Furthermore, most of the Yukon is actually pretty dry country. So .... I feel happy.

An electromagnetic field is with us like an irritating friend who we want to avoid but we can’t. Many of us are working a long hour before their computer desks and type a lot on their keyboard. Did you know that it makes your hand exposed to the harmful electromagnetic fields? FilterEMF solves this issue in the easiest way by designing RF shielding gloves.

A6 format postcard advertising the Disinformation concert, for experimental music promoter Lampo, Chicago, 16 April 2005. Disinformation performed with live and with pre-recorded radio (electromagnetic) noise sources, simultaneously projecting “The Air Pump” - a video made in tribute to the artwork of the same name by the 18th century painter Joseph Wright (aka Wright of Derby), and showcasing material from the “Sense Data & Perception” CD. The video featured high-voltage discharges through cold plasma vacuum tubes, and premiered at this Lampo event.
The concert was organised by Lampo proprietor Andrew Fenchel, and took place at the Pieholden Suite Sound (recording studio) in the Ukrainian Village (thanks also to Kevin Drumm, who, so rumour has it, had a hand in Disinformation being invited by Lampo). The postcard was screen-printed in thick ink on heavy card, featuring excellent Wyndham Lewis (“Blast”) style typography by renown designer Alisa Wolfson.
During this visit, Joe Banks also presented a “Rorschach Audio” lecture-demonstration at the School of the Art Institute of Chicago, at the invitation of the sound artist Nicolas Collins (author of the book “Handmade Electronic Music”, who also arranged the bulk importation of hundreds of Barrel of Monkeys for Joe). Lampo Spring 2005 performers were Disinformation, Malcolm Goldstein, Alexei Borisov and the Bohman Brothers. The concert immediately preceding Disinformation at Lampo was given by the sound artist CM von Hausswolff, who also lectured at the School of the Art Institute of Chicago... and this is particularly apposite, since the “Rorschach Audio” demonstrations expose and de-bunk the beliefs about Electronic Voice Phenomena (ghost-voice) recordings that form a central focus within the work of CM von Hausswolff.

Disinformation – “Antithesis”
Virtual exhibition for Schemata Art
Hosted by New Art City + Corsica Studios
March 2022 onwards (indefinite exhibition)

Curated and designed by Alice Hoffmann-Fuller, the latest exhibition in Schemata, Corsica Studios’ new experimental arts platform, takes place in a 3D digital rendering of Corsica Studios, hosted by on-line gallery platform New Art City. The “Antithesis” exhibition features brand new and archival work by the highly innovative and influential audio-kinetic art project Disinformation.
The Disinformation project’s exhibition for Schemata is in part inspired by the close proximity of Corsica Studios to the Brutalist architect Rodney Gordon’s iconic memorial to the electrical scientist Michael Faraday, installed, close to Corsica Studios, at the Elephant & Castle in 1961. The Disinformation sound artwork “National Grid” was first released on LP and performed live in 1996, and first exhibited as an art gallery sound installation in 1997. “National Grid” uses electromagnetic noise from live mains electricity to create a monolithic and immersive sound installation, which is conceived as a musical tribute to “the (creative) genius of electrification” [1]. The Michael Faraday memorial itself contains an electrical substation, which feeds high-voltage power to the London Underground; and it is consistent with the assertion that “art is not necessarily science, but science is always art” [2] that the original design for the Michael Faraday memorial envisaged this important work of public art as being a glass container (not, as it stands at present, a highly reflective steel box). On this basis, and in terms that are equally antithetical to the conventional wisdom of mainstream contemporary art, it can be argued that the true purpose of the architect’s original design was to enable members of the public to view what can be seen as the “real” work of art - meaning to view the electrical infrastructure.

A direct quote from the text:
"Illustrated here are 30 octaves of electro-magnetic radiation frequency (wavelength doubles with each octave). Visible light occupies only part of 1 octave. To represent the whole of the spectrum that has been detected, the piano would need to be drawn another 20 octaves wider" Postle, D. 1976
Electromagnetic fields can be shielded by the products specifically designed for this purpose. The product range is different because every electrically charged product emits electromagnetic fields and that has to be reduced.

“Pulsing sub-bass audio suggests associations with the most primal anthropomorphic element in music -- the rhythms of the human heart, with foetal and infant hypnagogic sense memories, with seismic activity, the rumble of thunder (Jimi Hendrix claimed that his earliest childhood memory was of a thunderstorm) and even with war. Disinformation's National Grid is a sub-bass installation sourced either from the ambient VLF field radiated by electricity pylons and mains circuits, or directly from the output cables of mains transformers. National Grid offers live physical evidence of environmental electromagnetic pollution, a demonstration of the intrinsic musical properties of alternating current, beat-frequency effects, the architectural acoustics of its own exhibition space, a formula for the realisation and suppression of Futurist sound art, a cathartic response to the pressures of urban life, a monolithic soundtrack for the genius of electrification and for the bitter conflicts between government and organised labour for control over the nation's electrical infrastructure.” - Disinformation “Stargate” + “National Grid” LP - Ash International, Ash 3.2, copyright © 1996
