I just want to write a note about Tiny Core Linux. I really like it. It is about 10MB in size and it boots with X and a very minimal Desktop in about 15 - 20 seconds using VirtualBox. I recommend to give it a try. Just download the ISO file and boot it. When booted you are able to install Firefox, gcc, GTK+, Text Editors and much more…

The radio tower of Hamburg, called “Telemichel (german)“. Okay, the right one is a little bit lame but it is a Warholdroid… :) The photos was taken with a HTC G1 and the software is called FxCamera. I don’t know the homepage, so if you wanna use it just just search for it in the Android Market.

Yesterday evening I have build a small relays for switching high voltage lines with my Arduino. It uses the “Blink” example and switches on for 10 seconds then switches off for 10 seconds. I have used this document to get my work done.

Relays switched off.

Relays switched on.

The next device is ready… ;) It is the TSL230R light sensor.

It prints out the Lux value every N seconds.

My code is based on this Blog entry. You could buy the sensor at Sparkfun where you will find the Datasheet too. Another place for code is here. There is provided a modified version of the link above.

Jehhaaaa… It is done!

My first Arduino device is born. Thanks to John! He learned me how to develop the driver for it. It is a DS1621 temperature sensor with 2-Wire (I²C) interface bus. And, YES! I have currently 17.5 degrees in my room.

I am impressed! The code will follow ASAP!
