This covers from 55 to 95MHz with a 65 to 5.5pF tuning capacitor change.
The lambda is formed by a BF256B and P1087 (with a nonstandard pinout), there's an additional BF256B acting as a source follower buffer on the output.
Put together by Charlie Docksteader. Sadly we have only memories of him now, a multi-faceted genius in technology.

This type of stuff is what I did in my career. Shown here: 1-2 GHz Yig oscillator, 1 GHz fixed oscillator, PIN diode leveler, LP filter, mixer, two amplifiers, sampler used for leveling and power set.

A handy side-effect of the christmas lights is that they maintain a stable room temperature thereby minimising oscillator pitch drift.

95 Amp Brick dual-SCRs work in series! 4 megOhm resistance in parallel with each SCR balances voltage. Capacitive compensation is also applied to each divider, .002uF 10KV across each 4 Meg resistor. The driver circuit is a relaxation oscillator time base. Charge pumping gives one output pulse for 6 line cycles. A DB3 diac drives a 4 Amp SCR, which dumps a .47uF 150V capacitor charge into the 28 turn primary of the toroidal gate drive transformer (taken from a microwave oven line filter). Four one-turn secondaries are made of teflon insulated wire with teflon sleeving slipped over them, loaded by 3.3 ohm resistors. Two 1N4007 diodes in series with each gate input assure noise immunity in the reverse half of each firing cycle. One driver transformer handles both push and pull phases of SCR gate drive. Two milliseconds after the initial firing, the inverse direction SCR fires by RC time delay, DB3-Diac, and another 4 Amp SCR.
The 466 after it was fixed, in mixed mode configuration. I made an LC circuit and am driving it with a function generator to produced the oscillations shown here.

Yeees I know... "I missed the arrow!!" Oh no, now I have to wait for another arrow to come up. Too bad.
Not really. A trend is a trend. Find the momentum and jump in. It does not matter -at all- if you missed the arrow. The mission of the PZ Bars indicator and the Oscillator is to let you find that momentum when it is safe to jump on a trend.
That was a buy stop order at the closest resistance line, with dark blue PZ Bars, a clear uptrend, and blue PZ Oscillator, meaning momentum was bullish. I simply traded the breakout.

This is a square wave oscillator with a LFO built into a vintage soothing sound machine.
Originally built by Marsona it looks original from the outside, although it has been completely rebuilt inside. The selector is now simply an on/off switch, volume is still volume, tone is now pitch, and surf rate and range are now now the LFO rate and range.
Guava-tree, small Lakhovsky - Oscillatory Circuit experiment.
From www.rexresearch.com/hhusb/hh5elc.htm
In 1924, Georges Lakhovsky devised his Oscillator Circuit, a one-turn copper coil with overlapping ends separated by a gap. Capacitance generates oscillating currents that benefit the plants. The ring is supported by an insulator such as a plastic rod. This extremely simple arrangement stimulates plant growth
A.K.A "Stumpy", or "MC Hammer", for his habit of slamming into the deck when not properly adjusted, which is pretty much always.
Symphony #1 for oscillators and internal combustion engine vibrations Live at the Athens Biennale,
June 27th,2009. A Lancia Y10 with a 1000cc f.i.r.e engine was used as the main
instrument. Additional vibration tests were made on a VW Kübelwagen at Kyriakidis
car lab in Athens, May 2009
The performance was part of ¨Live¨ exhibition curated by D.Papaioannou and
Z.Xagoraris for the Athens Biennale
Thanks to Yiorgos Kyriakidis, Kima Bo, Ektor, Nicolas, Anna Varoucha and all
the Biennale crew at Acharnon 8 and at the Esplanada
Performed,Recorded and Mastered by ILIOS

1. Product Overview :
SK6805-2427 is a smart LED control circuit and light emitting circuit in one controlled LED source,
which has the shape of a 5050 LED chip. Each lighting element is a pixel, and the intensities of the
pixels are contained within the intelligent digital interface input. The output is driven by patented
PWM technology, which effectively guarantees high consistency of the color of the pixels. The
control circuit consists of a signal shaping amplification circuit, a built-in constant current circuit,
and a high precision RC oscillator.
"Generalised Royer" oscillator to generate HV (over 1200V) from a 5V input.
Schematic: imgur.com/nplsqt5 (although this version uses two 68nF resonant capacitors in parallel, seems more stable)
There is a full wave rectifier and a voltage divider (total 750kΩ). The voltage is taken from the 1/5 division.

The periodicity of connected stationary oscillators is demonstrated on the example of a continuous, harmonic transverse wave generated by a wave machine. The number of oscillations carried out by different oscillators within a certain time is determined and the velocity of propagation is measured. A relation between frequency, wavelength and phase velocity is established. The formation of standing waves is demonstrated and studied.
Die Periodenzahl der angeschlossenen stationären Oszillatoren wird am Beispiel einer kontinuierlichen, harmonischen Transversalwelle, die von einer Wellenmaschine erzeugt wird, demonstriert. Die Anzahl der Schwingungen, die von verschiedenen Oszillatoren innerhalb einer bestimmten Zeit erzeugt werden, wird ermittelt und die Ausbreitungsgeschwindigkeit gemessen. Eine Beziehung zwischen Frequenz, Wellenlänge und Phasengeschwindigkeit besteht. Die Bildung stehender Wellen kann nachgewiesen und untersucht werden.
Works by some of the giants of American avant-garde music were performed Monday night by the Electro Acoustic Arts Ensemble Circus, six students in Kristian Twombly’s new media courses—John Cage’s famous “4’ 33,” James Tenney’s “Having Never Written a note for Percussion,” and Alvin Lucier’s “Music on a Long Thin Wire” were performed while excerpts from Cage’s “Lecture on Nothing” (1959). Loved every 30 minutes of it.
This is Lucier's piece performed on a long wire connected to loudspeaker terminals of a power amplifier with a sine wave oscillator connected to the amp--a sanitized description.
