# Polaron Polaron is a DIY digital drum machine based on the [Teensy 3.6](https://www.pjrc.com/teensy/) USB Microcontroller plattform. Main features: - 16 step sequencer - 6 instrument tracks - 16 patterns per track - load/save projects to SD card - 2 pots for parameter control - parameter locks: all instrument parameters can be recorded for each step - different pattern length for each instrument track - sync to midi-clock (usb-midi) or trigger input - crunchy 12bit stereo outputs - open source hardware/software: if you miss a feature or are annoyed by a bug... change it! Disclaimer: This is a DIY project, features may change or not work for you. Use at your own risk.    here's some short videos: https://www.youtube.com/watch?v=JC_pZTxMb0c https://vimeo.com/302283771 https://vimeo.com/305113707 Follow the project on Instagram: https://www.instagram.com/polaron.me/ And don't forget to check the [Project WIKI](https://github.com/zueblin/Polaron/wiki) for more info. ## Software To build the software, the following tools are required: - [Arduino IDE](https://www.arduino.cc/en/Main/Software) (tested with 1.8.6) - [Teensyduino Add-On](https://www.pjrc.com/teensy/teensyduino.html) (tested with 1.43) ## Hardware PCB is designed using KICAD 5.1.2 Parts needed (Rev 1.4): - Teensy 3.6 32bit Microcontroller (with Headers) - 30 x WS2812b RGB LEDs (or SK6812) - 30 x 6x6mm Pushbuttons (ideally 4.3mm height, 100gf) (Mouser: 688-SKHHAJ) - 16 x 270 ohm throughhole Resistors (Mouser: 603-MF0207FTE52-270R) - 14 x 270 ohm SMD Resistors (1206 housing) - 2 x 10k SMD Resistors (1206 housing) - 1 x 1N4148 diode - 1 x 2N3904BU transistor - 4 x SN74HC165N Shiftregister (Mouser: 595-SN74HC165N) - 2 x ALPS Potentiometer (RK09K1130A8G) - 2 x 2.2 uF SMD Capacitor (1206 housing, Mouser: 963-TMK316BJ225KL-T) - 2 x Audio Jack (SJ-352X-SMT) - 1 x 48 Position / 2 Row IC DIP Socket (Mouser: 517-4848-6004-CP) - 2 x 20mm PCB Standoff with 3mm thread (Mouser: 534-24437) Check the Wiki for [Build Instructions](https://github.com/zueblin/Polaron/wiki/Building-the-Polaron) ## Known Issues: PCB Rev 1.4 - In some situations, when connecting the polaron to a computer via usb and connecting the polaron audio output to an audio interface that is connected to the computer (e.g via thunderbolt), a ground loop is created. This results in a very noticable noise/whine in the audio channel (which is caused by the LED PWM). Tested solution: [Audio Ground Loop Noise Isolator](https://www.pjrc.com/store/audio_ground_isolator.html) ## FAQ - Q: Is this an easy build? A: This is an intermediate project to build. Its not very complicated, but there are some SMD parts which are not easy to get right (the LEDs). You'll need a decent soldering iron, with a rather fine tip. - Q: Is this a pro audio project? A: No, not exactly. The Polaron is more about a fun workflow than super hifi sound. - Q: Does it work with a Teensy 3.5? A: PJRC forum member drjohn reports successfully running the Polaron with a Teensy 3.5. - Q: Does it work with a Teensy 4.0 / 4.1? A: No, the Polaron relies on the internal DAC of the Teensy 3.6 and is not compatible with Teensy 4.0 / 4.1 - Q: Is there a manual? A: Yes, please check the [Project WIKI](https://github.com/zueblin/Polaron/wiki) for build instructions and operating manual. If you still have questions / suggestions, please send me a mail. - Q: Does the polaron fit into a euro-rack? A: No, not really (PCB size is 15.7cm x 11.6cm). Polaron builder N.Shaver has experimented with a 3D printable eurorack case for the polaron which he shares on [Thingiverse](https://www.thingiverse.com/thing:3830556) - Q: Can i buy a PCB? A: Sold out, but let me know if you'd be interested in buying one. ~~Yes, i currently have PCBs at 15 USD (+ shipping from switzerland). Please contact me by email, if interested.~~ - Q: Can i buy a part-kit? A: I don't sell part kits anymore, since it is very easy and efficient to order parts online, eg. from mouser. ~~Yes, i currently have part kits (PCB + all parts, EXCLUDING the teensy itself) at 60 USD incl. untracked international shipping. Add 5 USD for tracked shipping. Please send me a mail, if interested.~~ - Q: Can i buy a fully assembled Polaron? A: Not, not at the moment. - Q: How can i support this project? A: Spread the word, star the project on github, let your friends know, buy a PCB, build a Polaron and share a video...there are many ways. In general, knowing that this project sparks some interest is what keeps it going! # License Code: MIT Hardware: cc-by-sa-3.0 By: Thomas Zueblin (thomas.zueblin@gmail.com)
