    Dalek Synth

    Thanks taj-ninny. The potentiometers were bought from a local store in Melbourne called Jaycar. The knobs on the end I acquired from my father along with lots of tools etc. when he died nearly 30 years ago. I don't know were he got them from, he had lots of odd stuff in his workshop. I think...

    Dalek Synth

    I converted my toy Dalek into a synth. Inside is a Teeny 4.1 and Audio Card. The antenna and arms are potentiometers and joysticks and I used the fasttouch library for the touch buttons on the Dalek. Here are the innards...

    Dalek Synth

    I modified a toy Dalek I was given (its original function was broken) to become a bespoke synth. Here is a demo of it, version 1. The internals include a Teensy 4.1 and Audio card.

    Converted FCB1010 Drum machine for Practice with Friends - Teensy Modification

    I had already converted it to a synth during Covid lockdown for something to do. I wasn't using it, so it became a drum machine for practice with friends. Thanks for the info on the surface mount resistors.

    Converted FCB1010 Drum machine for Practice with Friends - Teensy Modification

    I play guitar with some friends, none of who are drummers. We also have to play quietly to keep the neighbours happy. So I have made a drum machine using the FCB1010 and by replacing the internal Microcontroller with a Teensy and audio board. This video shows how it works. Great for practicing...

    Teensy based Physics Note Generator

    Teensy based Physics Note Generator with twin Launchpads using USB Host A very basic Physics engine with pong style bouncing blocks to generate notes based on hitting edges of the "screen". The Teensy microcontroller interacts with the Launchpads which act as a screen and a keyboard for the...

    Teensy LC CV Sequencer

    Bespoke Teensy LC MIDI/CV Sequencer with Model D There are 8 bars in each sequence of 8 CV values or notes (for 64 steps). I can ‘draw’ the CV values by turning a Potentiometer (Knob) as the sequence plays. There are two independent CV sequences/outputs.

    Teensy Controlled Langtons Ant Sequencer - Demo

    As the sequence index travels horizontally (noteIndex), it calculates the the highest white and black squares (y) to decide the note to play. The notes are constrained to a key over one octave. void notesOn(int noteIndex) { lastNote1 = 10; lastNote2 = 10; lastNote3 = 10; lastNotey1 =...

    Dual LaunchPads with Teensy 4.1 using USB HosControl External Synths vis MIDI DIN

    Dual LaunchPads with Teensy 4.1 using USB HosControl External Synths vis MIDI DIN

    I have now used 2 launchpads as screens/keyboards to generate sequences for 4 external synths via MIDI. Two launchpads make it easier to have 16 steps in a sequence. Here is an example of it in action for Jamuary. Happy to answer any questions people might have.

    Wave Morphing With Teensy 4.1 and Audio Adapter. Nice!

    Thanks MatrixRat. The screens are a visualisation of the waveform stored in an array which is used by the Teensy audio system to generate a base wave that can be "played" at any frequency. From my physics background this is the carrier which can be altered by AM or FM. Of course any wave can be...

In the Sparkfun code, see below, they use io.begin(SX1509_ADDRESS)...

    Teensy Controlled launchpad Uses Conway’s Game of Life to Generate Notes

    I have updated the Conway's "Game of Life" note generator to send two different self generated patterns, one to each of the MIDI DIN outs so the Volca Bass and FM have different patterns. One is based on a cell dying (red), the other on a cell being born (blue). MIDI clock is also sent out each...
