In this video we will actually be looking at another video on YouTube. There the creator claimed that you can build a BLDC Motor driver with only 9 components. The catch is that ESCs (which are normally used for driving BLDC motors) consist of way more components and are usually quite complicated. So let’s “test” the circuit and find out all the information the original creator kept quiet about. Let’s get started!

Ritual Electronics Altar SVF & Miasma Distortion Eurorack Modules

We just started carrying Ritual Electronics modules and we made this bass sound with their Altar state variable filter and Miasma distortion. The Altar is a unique state variable filter in that it is an 18db/octave filter where most SVF filters are only 12db/octave. The Altar has continuously variable filter types and an input gain circuit that can overdrive the filter core for tons of dirty filter sounds.

The Miasma is a distortion with built in feedback routing that can lead to screaming self oscillation. When the Crime expander module is added to the Miasma you can use the rotary switches to select different combinations of diodes for different distortion types.

The drums in this video came from the Befaco Kickall and the WMD Crucible.

Plankton Electronics SPICE *prototype sounds & patches*

I don’t even really tell you what SPICE is, check it out here – – this is just a prototype unit I borrowed to check out the unit and support the Kickstarter. Selfishly (booooo selfish me) I’d love one of the final units in my own set up so by spreading the word and sharing this video I hope the campaign is successful so everyone has the chance to get hold of this killer little box. 3 filters, envelope follower, NuTube VCA and multi distortion, tonnes of CV control, feedback section. I like! Very nice!

Electronics: Introduction to LC Oscillators circa 1974 US Air Force Training Film

“In an LC oscillator circuit, the filter is a tuned circuit consisting of an inductor (L) and capacitor (C) connected together.”

US Air Force Training Film TVK 30-536

Electronics playlist:

Originally a public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current signal. They are widely used in many electronic devices. Common examples of signals generated by oscillators include signals broadcast by radio and television transmitters, clock signals that regulate computers and quartz clocks, and the sounds produced by electronic beepers and video games.

Oscillators are often characterized by the frequency of their output signal:

A low-frequency oscillator (LFO) is an electronic oscillator that generates a frequency below ≈20 Hz. This term is typically used in the field of audio synthesizers, to distinguish it from an audio frequency oscillator.
An audio oscillator produces frequencies in the audio range, about 16 Hz to 20 kHz.
An RF oscillator produces signals in the radio frequency (RF) range of about 100 kHz to 100 GHz.

Oscillators designed to produce a high-power AC output from a DC supply are usually called inverters.

There are two main types of electronic oscillator: the linear or harmonic oscillator and the nonlinear or relaxation oscillator…

Harmonic oscillator

The harmonic, or linear, oscillator produces a sinusoidal output. There are two types:

Feedback oscillator

The most common form of linear oscillator is an electronic amplifier such as a transistor or op amp connected in a feedback loop with its output fed back into its input through a frequency selective electronic filter to provide positive feedback. When the power supply to the amplifier is first switched on, electronic noise in the circuit provides a signal to get oscillations started. The noise travels around the loop and is amplified and filtered until very quickly it becomes a sine wave at a single frequency.

Feedback oscillator circuits can be classified according to the type of frequency selective filter they use in the feedback loop:

In an RC oscillator circuit, the filter is a network of resistors and capacitors. RC oscillators are mostly used to generate lower frequencies, for example in the audio range. Common types of RC oscillator circuits are the phase shift oscillator and the Wien bridge oscillator.

In an LC oscillator circuit, the filter is a tuned circuit (often called a tank circuit; the tuned circuit is a resonator) consisting of an inductor (L) and capacitor (C) connected together. Charge flows back and forth between the capacitor’s plates through the inductor, so the tuned circuit can store electrical energy oscillating at its resonant frequency. There are small losses in the tank circuit, but the amplifier compensates for those losses and supplies the power for the output signal. LC oscillators are often used at radio frequencies, when a tunable frequency source is necessary, such as in signal generators, tunable radio transmitters and the local oscillators in radio receivers. Typical LC oscillator circuits are the Hartley, Colpitts and Clapp circuits.

In a crystal oscillator circuit the filter is a piezoelectric crystal (commonly a quartz crystal). The crystal mechanically vibrates as a resonator, and its frequency of vibration determines the oscillation frequency. Crystals have very high Q-factor and also better temperature stability than tuned circuits, so crystal oscillators have much better frequency stability than LC or RC oscillators. Crystal oscillators are the most common type of linear oscillator, used to stabilize the frequency of most radio transmitters, and to generate the clock signal in computers and quartz clocks. Crystal oscillators often use the same circuits as LC oscillators, with the crystal replacing the tuned circuit; the Pierce oscillator circuit is also commonly used. Quartz crystals are generally limited to frequencies of 30 MHz or below. Other types of resonator, dielectric resonators and surface acoustic wave (SAW) devices, are used to control higher frequency oscillators, up into the microwave range…
