Hello again, everyone! Recently I was struck by a very harsh cold, and I have been unable to work on the project for the past weeks. Now I am slowly regaining my energy, though, so I have been able to pick up some work again after this long hiatus!   The past time I have been working with beginning to sew the suit which will be the first prototype of the music suit. First off I created a pattern for the lower part of it (since there was no pattern for a full body suit), using a book on pat ...
Welcome back for another Design Challenge Project Summary. For those of you who are new to my content, in this series I will pick a single project from the past week’s updates, and write a short summary of the project to date. Over the course of each challenge, I try to revisit each project at least once, and I am sure that some project summaries will get more than one update if they themselves are updated frequently. Some project creators like to keep their own project summary going, and ...
This blog post is about the redesign of the capacitive sliders.   As I mentioned, the electrodes will wrap around the side of the acrylic pad. This allows for the soldering points to be hidden and not on the side which is touched. This was a problem in the previous prototype. These tracks on the back will be covered by a strip of magnetic tape, which will fasten the pads to the legs.   Considering that I will be using a Roland GX-24 to cut A4 sheets of copper foil, I made this dra ...
At the start of this project I wasn't planning on having any kind of sound/patch storage or management within the vintage toy synthesiser, however as the project progressed I was more and more finding the need to quickly save and recall patches for both testing and demoing the functionality of the sound synthesis engine. In the end I decided to implement an external desktop application to handle this.   Approach  Synthesiser patch management allows the user to save the sound parameter ...

Background  Put simply the PlectralEFFECTS project is a new form of input that a guitarist can work with in their performances to trigger effects. Instead of effects being triggered in more traditional manners; Pedal or envelope follower, PlectralEFFECTS takes a new approach.  Striving to achieve accurate timing and direction in which the string was sounded for a broader variety of audio genre / styles. The project has evolved to provide MIDI stream. Plectrum input information, ie. P ...
Update  Greetings!   This is just a quick update, I have a lot more to cover which I will.  A few of the components for the design challenge arrived, no sign on the BBB? I have decided to not keep waiting any longer for kit to arrive, I have commenced working with existing components that I have on-hand namely an Arduino LeoStick.   The LeoStick contains an ATmega32U4 micro-controller.  The ATmega32U4 provides, USB (HID compliant), 32K Flash, 2.5K RAM, 1K EEPROM and ...
My last weeks post involved, Controlling and Monitoring your 3D printer with BeagleBone and OctoPrint  and this week has involved, a lot 3D designing and 3D printing an enclosure for Pocket version of DIY Drum kit using the SparkFun's Capacitive touch key pad (https://www.sparkfun.com/products/12017) ,a couple of potentiometers(10K Ohms) and the BeagleBone black.   I had to name the blog post  -- "Pocket version"  of the DIY drum kit , as i could not come with something fanc ...
Hey!   Today I have done the next steps of 3D modelling in order to build my prototype. The pads will now have 6 electrodes each. This is due to 7 pins on the MPR121 breakout boards becoming available, as I am no longer going to use rotation and magnets to change key and access the menu.   These pads will be laser-cut from 1mm clear acrylic sheet. The electrodes will be cut out of adhesive copper foil like in the previous prototype, but this time the tracks will wrap around the ac ...
Just over a month ago I posted about the implementation of the audio synthesis engine for the vintage toy synthesiser, however since then I've got the synths front panel developed and fully working which has allowed me to rapidly complete the main features of the synth. Here I'm going to follow on from that blogpost and talk about the final few features I've implemented since then, however it's worth mentioning that there are still a few refinements I need to make before I can settle on a final ...
  A few years ago I was one of 20 winners in a worldwide screen writing competition. Pretty cool eh?   The prize was 18 months of tuition and script development with an established screen writing tutor, which has paid no end of dividends. One of the many lessons that really stuck with me was about the writer's role within the film making team. He explained that a movie is the vision of literally hundreds of people -- not just the writer. He brought this up early as he's well aware th ...
My project the DIY drum kit is going to include quite a bit of 3D printing, which meant that I had to try out setting up OctoPrint (OctoPrint.org )on the BeagleBone black, which would give me a web enabled UI to control,3D print and monitor my printer.   I have been using OctoPrint for more that six months using a Raspberry Pi B+. Setting up OctoPrint on the Pi was pretty simple, which include flashing a modified image of Raspbain called OctoPi, but in case of the BeagleBone you will ...

Hi everybody,   Last week I worked on the structure for the next prototype.   The first model, which I finished last Monday was designed to fit the maximum printing dimensions of an Ultimaker 2 printer (with some margin). This is somewhat smaller than the current prototype and designed in only 2 parts. However, after taking my model to the printer, I realised that the real bounding box was in fact significantly smaller than the one specified. I then tried my luck on 3Dhubs.com but I ...
Last week I posted about the design and construction of the front panel for the vintage toy synthesiser, however another thing I had been doing alongside that is putting together the electronics and software for allowing the synthesis engine to be controlled by the panel controls. This ended up being a bit of a nightmare to get working well as I'll talk about below, but I think I've finally got it into a stable state. A lot of the electronics and software for the panel is very similar to that of ...
Even though I ended up constructing a brand new front panel for the toy piano for this project, the rest of the enclosure of the vintage toy synth will be using the existing piano enclosure. Apart from the front panel, the other part of the piano that needs modifying for the project is the back section where I need to add a set of sockets and controls so that the synth can be easily connected to a power source, an audio output, and external MIDI gear. A second part to this task was connecting th ...
This is a tutorial to record a .wav file, using ALSA -arecord when a button a pressed, and then upload the recorded file to Soundcloud.com , as shown in the video below     Here are the steps you will have to follow - #1 Setting up USB audio sound card  on the BeagleBone Connect a  mic and speaker to the USB sound card and SSH into the BeagleBone to run the commands below.

Hi everyone,   I feel like I have been stuck in the world of Pure Data for most the past three days. *head spinning*   I have managed to get values from all four MPR121s flowing into Pd (again with the help of Chris from the Bela platform team). Unfortunately, the results aren't as great as I was expecting so I might have to change part of how the pads work.   Changing the C code I started off looking at the example for the MPR121 (which doesn't use Pd) and looked for anything t ...
You might find this interesting. I do     Cheers! ...
The front panel of my vintage toy synthesiser is the place where all the dials and buttons for controlling the sound parameters will be attached to the toy piano. While the final design of the panel has turned out very similar to how I had originally planned it to look, the construction of the panel compared to my initial plan has changed dramatically. In this blogpost I'm going to cover the process of both designing and constructing the front panel for the vintage toy synthesiser, which has bee ...
