Case for STM32F4-Discovery Board

I finished a case for the STM32F4-Discovery board. It consists of two parts: the case body and the case cover. The cover is hold in place by two snap-ins. The cover has spaces for all the header, jumpers and buttons. Also I made the cover very thin at the places where the LEDs of the board […]

Micro Python on STM32F4-Discovery

The Micro Python project is an effort to make the Python3 language fast and lean enough to run on micro controllers and if was successfully founded by this KickStarter campaign. It is intended to run on it’s own hardware, the pyboard. Unfortunately, this board is not widely availabel, and everyone who missed the KickStarter will not be […]

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 […]

A Tin Can Robot – Roundup

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

A Tin Can Robot – Basic Schematic

Documentation day today :-). I got also around drawing a basic schematic (using Fritzing) for the tin can robots electronics. Some notes on the schematic: I don’t use the Propeller “directly” but use the Propeller QuickStart board. The schematic below is soldered on perf-board and then attached as a shield to the QuickStart. Fritzing offered […]
