Bric(k)-o-lage – Blockly

Here are some screen-shots of the Blockly based visual programming editor for Brick-O-Lage. Roughly it works like this: On the Master Brick, the bolsrv is running. bolsrv uses libbol to access the bricks connected to the master via I2C bolsrv also includes a mongoose based web server doing two things: serving the HTML+JavaScript based visual editor […]

Bric(k)-o-lage – DCM Brick

Recently I finished a first version of the DCM Brick (DC Motor Control).  As for the DIO brick and the Master Brick, I designed schematic and PCB using fritzing . Also I ordered the PCBs from fritzing FAB. For the firmware I used my own libemb as a basis. The DCM brick allows driving two DC motors independently.  Each motors direction (clockwise […]

Bric(k)-o-lage – Bric(k)-o-Mess

Master Brick, two DIO bricks (in the back), a breadboard proto of the DCM brick (one Launchpad for the proto, one for programming the DIOs).

Bric(k)-o-lage – Master Brick

Also long time ago finished: the master bricks PCB and large parts of the firmware. Currently the MB is already able to drive the DIO and DCM bricks (multible of them). As before, I designed schematic and PCB using fritzing and ordered the PCBs from fritzing FAB. Currently I have not designed a case for the MB (since I […]

Bric(k)-o-lage – DIO Brick

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 […]

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 […]

Poor Mans Scratch Sensor Board

“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 […]

Carambola SoC Stand Alone with MSP430 Piggyback

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 […]

ROCKETuC Introduction

I just made two short videos introducing the main features of the ROCKETuC project I work on with Alexander Reben. The first one gives a basic introduction to ROCKETuC and what you can do with it, the second one shows how external interrupts could be used with ROCKETuC and Processing. Basically I made them to […]
