SparkFun Solderable Breadboard – Large

This is the Large SparkFun Solderable Breadboard. A bare PCB that is the exact size as our full-size breadboard with the same connections to pins and power rails. This board is especially useful for preserving a prototype or experiment you just created on a solderless breadboard by soldering all the pieces in place. The large solderable breadboard also includes real estate for screw terminal connectors and a trace down the center gutter for ground.

UltrasonicSynth Mozzi

Oscil

Oscil plays a wavetable, cycling through the table to generate an audio or control signal. The frequency of the signal can be set or changed, and the output of an Oscil can be produced with for a simple cycling oscillator, or for a particular sample in the table.

Soundtables

Look-up-tables and python scripts to generate tables or convert sounds. Includes ready-to-use wave tables and a few example samples. Also check out the other scripts in the python folder for templates to use if you want to do your own thing.

Smooth

A simple infinite impulse response low pass filter for smoothing control or audio signals. Smoothness sets how much smoothing the filter will apply to its input. Use a float in the range 0 – 1, where 0 is not very smooth and 0.99 is very smooth.

AutoMap

Automatically map an input value to an output range without knowing the precise range of inputs beforehand.

Theremin

The theremin was invented in 1920 by a Russian physicist named Lev Termen. Today, this marvelous instrument is once again in the musical spotlight. Besides looking like no other instrument, the theremin is unique in that it is played without being touched.

Two antennas protrude from the theremin, one controlling pitch, and the other controlling volume. As a hand approaches the vertical antenna, the pitch gets higher. Approaching the horizontal antenna makes the volume softer. Because there is no physical contact with the instrument, playing the theremin in a precise melodic way requires practiced skill and keen attention to pitch. The electric signals from the theremin are amplified and sent to a loudspeaker.

In the late 1920’s, RCA produced approximately 500 theremins, manufactured by General Electric and Westinghouse. Today, it is estimated that only half of these still exist. The spooky sound of the theremin was used in several movie soundtracks during the 1950’s and 1960’s. Electronic music pioneer Robert Moog built theremins long before he built synthesizers. In the 1960’s, he produced such models as the wedge-shaped Vanguard theremin and the shoebox shaped Moog Melodia theremin. It provided background mood music for such sci-fi classics. During the 60’s and 70’s, bands such as Lothar and the Hand People, the Bonzo Doo Dah Dog Band, and Led Zeppelin brought the theremin into the public eye for a short time.

Theremin + Arduino Pro Mini + Ultrasonic Sensor + Mozzi

Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. This is the ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality. The ultrasonic range detectors replace the antenna of the traditional Theremin. Control the frequency (pitch) of the output. Operation of the sensor is straightforward. The Arduino sends a digital pulse to the TRIG pin of the sensor causing it to emit a burst of high frequency audio. If an echo is detected the sensor toggles the ECHO pin which is monitored by the Arduino. By measuring the time delay between the outgoing pulse and returning echo we can calculate the distance. As sound takes 29 microseconds to travel one cm, and must travel out and back, we can divide the time to the echo by 5.8 to get the distance in mm. The project uses the Mozzi audio library to generate a sine table for oscillator which is sent to the output.

The AcceleroSynth 2012

——

Synthesizer, Music Synthesizer Or Electronic Sound Synthesizer

Synthesizer machine that electronically generates and modifies sounds, frequently with the use of a digital computer. Synthesizers are used for the composition of electronic music and in live performance. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments. A electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms, through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies, envelopes, which control articulation, or how notes begin and end, and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre.

The AcceleroSynth – 2012

We are finally ready for our first electronics project, The AcceleroSynth. It is an microcontroller-based (Arduino) music synth that is controller by a 3 axis analog accelerometer. It will be both a hardware and a software synth. This is the announcement for the project and in the coming days I will post the BOM (Bill of Material), schematics and Arduino code with the first assembly video. The project will first be assembled on a protoboard, then a soldered version will be built either on a perfboard or on an Arduino ProtoShield. If there is enough demand either a PCB or an Arduino Shield will be built for the project and sold here. More on that later. The first installment on the building of the project should be up on a few days.
