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 […]

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 […]

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 – 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” […]

Window-Thing

Today I think I 3D printed my first real useful thing. This “thing” sits on the bottom border of our windows and helps keeping them pack (against cold air). Unfortunately I don’t know the name of this thing, so I decided to call it the “window thing”. One of our windows was missing the “window […]

A Tin Can Robot – Final Assembly

All parts are printed! Now everything is ready for a first assembly. But first the electronic components need some wiring: The full BOM for the electronics looks like so: 1 x Parallax Propeller QuickStart Board 2 x gear motor 2 x wheels for gear motor 1 x Pololu 3.3V Step-Up/Down regulator to supply the Propeller […]

A Tin Can Robot – The Inlay

Finally the inlay which will hold the batteries and the Parallax Propeller.
