Pynetsense is a Python library that provides a simple to use API for implementing Scratch networking sensor clients. For communicating with Scratch, the remote sensor protocol is used. Beside providing a simple API to manage messages and variables, a wrapper framework is provided. The wrapper framework helps with implementing sensor clients that run in the [...]
“scratch-sherpa” implements the protocol of the Scratch Sensor Board (also known as Picoboard), as supported by the educational Scratch programming environment. A MSP430 Launchpad with my uSherpa firmware as foundation is used. For more details, see the project page here Get the sources from github The (unedited) video below shows some examples of how the [...]
Like I wrote in this article, it is pretty easy to run the Carambola SoC stand alone. Today I finished the Carambola-MSP430 (for MSP430 stand-alone see this article) Piggyback I intend to use as a replacement for the current jumper wired brains of my Carambot. The Carambola comes with 2mm pin connectors, I used a [...]
I just was playing around a little running the Carambola SoC stand alone (without dev-board). The picture blow shows what needs to be connected to boot the Carambola, access it through serial line (by using a TTL USB to serial converter), and optionally connect USB (I used a web cam): Some notes about power consumption: [...]
My little installer script for helping setting up a Propeller Tool-chain on Linux/ARM, also mentioned on hackaday last month, was chosen for “project of the week” from Parallax (the makers of the Propeller).
Gave “pyscmp” a first try on the Pi, works so far (some minor issues regarding dbus and jack-audio).
It seems to get usable (somehow). “pyscmpd” is now able to do basic play-list handling and playing. Both, “ncmpcpp” and “sonata” are able to browse the tracks of a predefined set of soundcloud users, add the tracks to a play-list and play them. Also the elapsed song time is transmitted to the clients, as well [...]
Since I do have so many projects running currently I decided it would not hurt to start an other one. It is a Python based soundcloud music server talking the MPD protocol. Thus, pyscmpd allows (not yet, but maybe in future), to serve music from soundcloud to any MPD client out there. Currently I am [...]
I just received a bunch of Raspberry Pis and though I give the propeller tool-chain installer script I wrote earlier about a try. Here is what a did on a fresh Raspbian “wheezy” to get it work. 1) Install needed dependencies sudo apt-get install git subversion mercurial texinfo flex libncurses5-dev python-serial 2) Get the Script [...]
