It looks like I jumped the gun a bit with upgrading to the latest version of Debian on BBB if I wanted to use beaglebone-io. Bonescript, the JavaScript library for working with the GPIO pins that beaglebone-io is built on top of, does not work correctly with the newer 4.x kernel that is included with Jessie (i.e. version 8.3) because the paths for the cape manager devices are different with the newer kernel. So I may need to downgrade back to Wheezy (version 7.9) if I want to use this particular ...
I’ve spent the past 10 days in sunny Anaheim, California at The NAMM Show 2016 exhibiting with Modal Electronics, so I haven’t had much time to work on my project. However it’s given me a chance to think a lot about my synthesis engine design, so I thought I’d use this weeks (well, a late last weeks) update to give a brief overview of audio synthesis types, the essential components, as well as outlining my current design ideas and how they have changed over the project so ...
Hello again!   I've been waiting to begin most of my work until my kit arrives, but as I am still waiting for it to arrive I realized I need to get some work done. Since our local SoftLab has opened up about a week ago, I began working at the same time as it opened up. In the video below you will be introduced to the working place and what potential it carries.     (For all fellow Flash refusers out there: https://goblinrefuge.com/mediagoblin/u/fraktalize/m/intro-to-softlab/& ...
Hey everyone! I hope your projects are coming along alright. Don't forget that you can get in touch with me if you have any questions or need a bit of help with something.   I recently got to spend a little time learning about one of our challengers' projects, whilst a version of it was on show at TEDx Teen in London. Check out the video below to see how it went     Coming up in the next episode, you can see my progress on my own project, LaserScope Music. So far I have not ...
My motivation for the hexynth project is to produce a system of snap-together modules that can be programmed, that I can use to teach coding and tech skills alongside sound synthesis concepts. I use the johnny-five JavaScript Robotics framework in many of my workshops at the moment, so the JS library that I'm writing to go along with the hardware modules is building on this framework. Johnny-Five runs on the BBB using Node.js with the beaglebone-io module. This article steps through using beagle ...
BBB Paint and Play Drum Set      This Project is all about designing Open source, Low Cost and innovative Drum set using BBB as main sound generating Unit, and ESP8266 Based wireless drum sticks and pedals. I have given name "Paint and Play Drum Set" to this project because one can paint any surface or simply any paper with different color and shapes in artistic way and program the stick to recognize each color using TCS3200 Color sensor to generate different MIDI notes o ...
This week, for my design challenge project, I've been attempting to get started on the sound synthesis engine for my synth, as well as setting up an audio output on my BeagleBone Black. There have been quite a few frustrating evenings in doing this, and while I now finally have synthesised sound coming out of my BBB, it looks like I may need to rethink what library I'm going to use to make my synthesis engine, or redesign and simplify my original idea for the synthesis engine.   USB audio o ...
I'm waiting for the MusicTech challenger kit parts to make their way downunder, so in the meantime I’m experimenting with an old BeagleBone Black. It’s a couple of years old, so I figured I would install a new image on a micro-SD card to make sure I'm using a recent OS. I'm not sure what OS the BBB in the challenger kit will have onboard, perhaps it will be fairly recent anyway, but this process is also useful to make sure I have a backup of everything on the micro-SD card in case I ...
Table of Contents Introduction: After long thinking about musictech design challenge Project, I have decided to design Open source, Low Cost and innovative Drum set using BBB as main sound generating Unit, and ESP8266 Based drum sticks and pedals.    Paint and Play Drum Set includes,      1. BBB as Drum bit MIDI Synthesizer.      2. Two Wearable Pedal      3. Two Identical Drum Stick      4. And ...
Hey everybody!   I hope everyone's projects are starting to get off the ground - and don't forget that you can reach out to me with any questions that you have. I just wanted to make a post to discuss the project that I'm going to work on during the challenge...   Also - to all of our challengers, feel free to use my project outline as a bit of a template if you've not posted yours yet. Don't forget that each project needs at least 15 blog posts (which averages out at 1 for each week ...
After completing the majority of the key mechanism for my vintage toy synthesiser, which I covered in my last blog post, I thought it was about time I cracked open the BeagleBone Black board and attempted to connect the key mech to it. Setting up the BBB for my preferred development language and environment, as well as getting the Arduino-to-BBB comms working, was a bit more complex than I thought it would be, nevertheless I have now got the BBB receiving key interaction data from the keyboard. ...
If you read my last blog post you would have seen that I started my project by prototyping ideas for the digitisation of the pianos key mechanism. Well, after spending the best part of a week attached to my soldering iron and multimeter I've finally completed most of the electronics and software for the final implementation of the key mech. The implementation for detecting key presses and releases has changed considerably since my initial design, and I've still got a bit of software tweaking to ...
To see all my post about this challenge新年快樂! 因為比賽的套件還沒到,在家有空來寫這篇。看看我手邊可以用的東西有哪些? 1.蓮霧派: 台灣設計台灣製造的產品,媲美樹莓派,但是有更大的RAM(2G)。目前支援Debian 8.1與Android 5.1.1。   2.YRPBRL78L12: 參加瑞薩研習課程送的開發板,搭配RL78/L12晶片,板子上搭了瑞薩的LCD。   3.STMICROELECTRONICS  NUCLEO-F411RE  DEV BOARD, STM32F411RE CORTEX-M4 MCU ST的Nucleo系列開發板,搭配STM32F411RE晶片,有相容Arduino腳位。可在mbed開發。   4.YL-KL26: 中國製的開發板,搭配Freescale(現在合併成NXP了) KL26晶片,板子上有可變電阻、蜂鳴器、觸碰按鍵、LED、EEROM,學習很方便。   5.RASPBERRY-PI  RASPBERRY ...
