In the recent days Bitsphere did some hardware assembling due to the great open source work of Marco Donnarumma called x-th sense. An open hardware project which aims to amplify muscle sounds. The local hardware distributor here in Switzerland offered all the pieces need for the assembly except the “protokit” mentioned in the xth-sense documentation and the sensor is build in less than an afternoon by a newbee to hardware assembling for the on-line documentation is really detailed.
Bitsphere replaced the protokit with a “Hammond Manufactoring 1593KBK Handheld Box”, sawed a piece out of an epoxy fibre-glass labor card (the RE523-LF by Roth Elektronik) which fits in the box and screwed it into the box. That is about the pieces the original kit consists of.
To get the software running was the harder part. It was not that easy to get the required version of puredata extended. Finally it turned out there is a repository for the beta builds with the required versions. Then the directory names mentioned in the x-th sense how-to have to be created on the local disk the very same.
For those interested in readings about body sounds you find an article about biomusic in the Journal of Sonic Studies.
