Poor Mans 3D Goggles (OpenDive)

At Google I/O this year, Cardboard was presented. Cardboard are DIY 3D goggles made of cardboard, using a smart phone as screen and sensor device. Cardboard seams to be based on OpenDive from Stefan Welker who also published the STL files for 3D printing his goggles on ThingiVerse. And printing them was exactly what I […]

Bric(k)-o-lage – Big Button

I created a first passive component for my brick-o-lage project: a big button with feedback LED. The button is mode from a big “pilz” switch which presses a smaller switch inside the case. Very simple but dangerous looking :-). The 3D files could be found on my github account. I tried to make the case […]

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 […]

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 – 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 […]

A Tin Can Robot – Roundup

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

A Tin Can Robot – Short Video

Ok, the hardware for both robots (black R2D2 and pink R2KT) is done. Also a first version of the software is loaded on the Parallax Propeller inside the two bots. In the video below you could see them driving (remote controlled from smartphone/tablet).

A Tin Can Robot – R2KT on it’s Way

A Tin Can Robot – Driving

The tin can based R2D2 robot driving around, remote controlled through tablet using Bluetooth: The sound in the video is pretty poor. But what you here so far is a typical R2D2 beep-beep on start-up (or when you request it by remote command), an other beep when a new command was received, some sad “ohhhh” […]
