The DIO (Digital IO) brick for my brick-o-lage project is already finished. I designed schematic and PCB using fritzing . Also I ordered the PCBs from fritzing FAB (and they turned out great). For the firmware I used my own libemb as a basis. DIO Brick Specifications Uses a MSP430G2553 from TI Runs custom firmware […]

Bric(k)-o-lage – smart bricks the “bricolage” way

A while ago, I started a new project trying to create different “smart” bricks which will interconnect with some other well known brick systems (e.g. Lego). By “smart” bricks, bricks are meant which are able to perform a certain functionality like driving LEDs, detecting button presses, control DC motors or servos, read sensors and so […]

A Tin Can Robot – Roundup

I put together a project roundup for the tin can R2D2: TinCan R2D2 roundup

A Tin Can Robot – Android App to Control

Finally I got around hacking a basic Android App to control my tin can robots. To quickly get a result, I used Processings Android mode and the Ketai library for the Bluetooth stuff. Regarding the effort needed for the results, they turned out pretty well. The App has the following features so far: Device Discovery […]

MSP430 I2C Slave Example

Since none of the examples I found worked for me, I put together my own example which shows how to use the MSP430G2553 as an I2C slave. The MSP430 takes some simple commands. One for switching the build in LED (P1.0) on/off, one for reading the state of the build in button (P1.3). Also a […]

Measuring the Water-Level of a Cistern

To measure the water level of our cistern, I started to build a little cistern monitor based on a hacked TP-Link MR3020 router running OpenWrt and a SRF05 ultra sonic range finder. The software project mainly consists of a kernel module and a web service to access the data through a simple web-ui or by […]

Scratch Remote Sensor API

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 […]

Propeller-Installer Project of the Week at Parallax

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).

pyscmpd Running on the Pi

Gave “pyscmp” a first try on the Pi, works so far (some minor issues regarding dbus and jack-audio).

pyscmpd Making Some Progress

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 […]
