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 – Electronics

I roughly put together most of the electronic parts needed to make the robot drive. The video shows operation of the two motors through my cellphone using Bluetooth. Also I added basic playback of PCM audio files through a speaker I connected to the Propeller. The audio is a must to play back the typical […]

Cracking a Sansa Shaker Open

Here are some pictures showing how to crack a Sansa Shaker MP3 player open. The main “trick” is to remove the two rings (which one uses to control volume or skip tracks). After the rings are removed, the cover could be taken into two half’s by removing the small screws which are hidden under the rings.  

Record from Webcam to OGG with GStreamer

Using gstreamers gst-launch, one could easily record the live stream from a webcam directly to an OGG-container using theora-encoding. By splitting the input from the v4l source (through “tee”) into two parallel sub-pipes, it is possible to show the recorded stream on the screen, while saving it to the OGG-file on the other processing path. […]

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 […]

Carambola SoC Stand Alone

I just was playing around a little running the Carambola SoC stand alone (without dev-board). The picture blow shows what needs to be connected to boot the Carambola, access it through serial line (by using a TTL USB to serial converter), and optionally connect USB (I used a web cam): Some notes about power consumption: […]

Installing a Propeller Tool-Chain for C and SPIN

Lately I started playing around with the Parallax Propeller Quick Start Board. Since I found it a little hard to puzzle together a Linux tool-chain supporting C/C++ and SPIN development for Propeller on Intel based as well as on ARM based machines, I wrote a little installer script which helps in setting up a tool-chain […]

Hallo Carambola

Today I got my Carambola boards (thank you Matze). The Carambola is a MIPS based SoC from 8devices. It uses the Ralink RT3050 which includes a high performance 320MHz MIPS24KEc CPU core, 8 MB Flash and 32 MB RAM. The device also provides two Ethernet ports and w a 802.11bgn radio. And best of it all: it is […]

A Modern Linux System …

.. like Xubuntu is a great thing. It allows you … OK, we already head this before, so I will get to the point: Why are all Linux desktop distributions sucking so much nowadays? Today I had three moments of “what the … happened to Linux?” within only one our …
