Printable Variable Miniskiff

 

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 Bambu P1P

Tiptop Buchla Eurorack Case 3D Printed

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 with how this #3dprinting turned out on a @bambulab_official P1P with the Bambu basic PLA!

Mediapipe Hand Solution on Raspberry Pi to OSC to Modular CV / Gate

Setup: 

1. Set up a Raspberry Pi 4 with a clean install of Raspberry Pi OS: https://www.raspberrypi.com/software/ 
2. Install Mediapipe as per the instructions here: https://github.com/googlesamples/mediapipe/tree/main/examples/pose_landmarker/raspberry_pi
3. Install Python OSC on the Raspberry Pi: https://pypi.org/project/python-osc/ 
4. Add detect_osc_pi.py (https://github.com/little-scale/Tele-o-Module/blob/main/software/dectect_pi_osc.py) to mediapipe/examples/hand_landmarker/rasperry_pi
5. If using my Tele-o module (https://little-scale.blogspot.com/2023/01/tele-o-wifi-bluetooth-to-cv-gate.html) replace ip in detect_osc_pi.py with the address of the ESP32 in the module. 
6. If using a different OSC endpoint, replace ip in detect_osc_pi.py with the appropriate address. 
7. It may be beneficial to change the port variable in detect_osc_pi.py - the default is 3000
8. Pressing together or releasing the thumb and index finger sends a 1 or 0 on OSC path /gate/0
9. The distance between the thumb and index finger sends a float 0 - 1 on OSC path /cv/0
10. The X and Y co-ordinates of the index finger are sent as floats of 0 -1 on OSC paths /cv/1 and /cv/2
11. These OSC paths can be changed with the variables near the top of detect_osc_pi.py

Simple Cinemag CM-DBX Transformer DI

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 - XLR pin 2 and brown for negative - XLR pin 3) to the XLR jack, as well as the chassis of the secondary coil to XLR pin 1 (ground)ses Cinemag CM-DBX for the transformer, 

I used Jaycar part PP1023 for the XLR jack and Jaycar part PS0162 for the 6.5mm mono socket. Even though the box is plastic I have not had any noise issues yet but this will depend on environmental conditions. 

No issues with modular levels going through the transformer so far! So it can handle pretty hot signals.

I made a sketch for my Secret Handshake USB host module to control Eurorack using a GameCube controller (with a GC to USB adaptor).

Xiao M0 USB MIDI Clock Sync Example

I made a simple example for a Xiao M0 USB MIDI clock sync setup. This can be used to sync external gear to a computer via USB MIDI, but this also works for iOS devices and anything that can act as a USB host for standard MIDI devices. An easy way of syncing stuff to Ableton Link via the free Link to MIDI iOS app for example as well!

Sending a Clock Signal to Modular Synth via WiFi

Sending an Ableton Live clock signal over WiFi to my modular synth using OSC, ESP8266 and Max for Live . The sync appears out of order because my DIY Exo Sequencer module doesn't have a reset input but overall the timing and tempo changes work really well - considering the setup.

Using Modular Synth to Control Atem Camera Switching over WiFi using ESP8266

I've been wanting to control my camera switching from my modular synth. So I made a setup where a low to high transition on a digital input on an ESP8266 module generates an OSC message on the WiFi network for the ATEM Mini Pro switcher to change cameras. Here, it's triggered from the kick but it could be any clock, gate or trigger signal. Makes use of atemOSC.
