Breath sensor made from an MPXV7002 and a silicon tube. The tube has incisions added near the breathing end to allow air to flow through while still building pressure at the sensor end. Enough pressure is still built up within the tube to allow circular breathing if desired. The sensor sends note on / off and continuous control data. To improve this I might consider a wider tube that is coupled…

Overview The VL53L0X is a ranging sensor that uses time-of-flight of a laser to determine the distance to the next surface correct to the mm with a maximum of 2m. The sensor uses an i2c interface with a default address of 0x29. The xshut pin allows for address control and start up / shut down during setup. Hardware Setup Here are the pinouts for the Teensy 4.1 and the VL53L0X: Make the following…

View this post on Instagram A post shared by Sebastian Tomczak (@littlescale) My pyramid controller is almost identical to my sphere controller . The difference in shape means that each side feels a little like a preset, and its easier to have an intuition about rotation and orientation compared to a sphere. The code is slightly different as it doesn't adjust brightness; this looks better in my…

I've added a variable miniskiff part studio to the Eurorack case document: https://cad.onshape.com/documents/1637ca71f6ccbf900471de5e/w/ba5b8495e9753650883d1cb0/e/c3f73f4b0fd00e64b5823644?renderMode=0&uiState=656884e93534192f492a1c3b This part studio has variables for many aspects of the case including the width in HP. 46 HP is the widest case that will print on a 25 cm 3 volume printer like the…
So the @tiptopaudiofficial #eurorack #modular #buchla series modules are a total of 2HP too long to fit in a standard 104HP case. I designed and printed a 108HP case with space for a uZeus power supply module. The minimal design is the perfect shape for these modules, and due to the large size is printed in six sections. I've also included a 1HP blank to fill the space of the top row. Really happy…
Download here: https://github.com/little-scale/mediapipe-object-osc Adds basic OSC output for the Mediapipe object detection solution By default, OSC will be sent to 127.0.0.1 localhost on port 3000 and with address /mediapipe/objects. This can be changed in utils.py Each OSC message contains: Category name, object detection instance within the frame, normalised x position, normalised y position…

I made some musical sphere controllers. They use the Adafruit Feather Sense BLE nRF5284 board. Axis in six dimensions can be mapped to MIDI outputs via a Max patch. Details including code, patch and 3D files can be found in the github repo here: https://github.com/little-scale/Music-Sphere-Controller
I wired up a simple DI for my synths as I wanted to balance the output as well as push the signal through a transformer. I used a Cinemag CM-DBX transformer. I connected the primary coil (yellow for positive and orange for negative) to the 6.5mm mono socket, as well as the chassis of the primary coil and shield of the transformer to 6.5mm ground. I connected the secondary coil (red for positive -…
Overview The QMC6310 magnetometer sensor outputs 16 bit for each axis X, Y and Z. The code uses the Wire library to communicate via the I2C protocol. This example prints the raw axis values to the serial monitor and also sends as a USB MIDI control change message (scaled to 0 - 127). The datasheet for this sensor can be found here . Hardware The following connections should be made between the…
An SM-24 geophone (Sparkfun part SEN-11744) with a rare earth magnet ( Jaycar part LM1626) to attach to metal surfaces. The pin on the geophone with the notch is the positive terminal. This should be wired to XLR pin 2. The other pin of the geophone is the negative terminal. This should be wired to XLR pin 1 and 3. Additionally, a 10k resistor should be wired between pins 1 and 2 of the XLR. Note…
Overview An encoder is a digital input device that looks similar to a pot but can be rotated indefinitely and delta rotation in steps is measured by making or breaking contact between two pins and ground. The Teensy has an excellent and easy to use library for encoders. More than one encoder can be easily used. Hardware The encoder portion of an encoder usually has three pins, these may be…
