SFH 3310 & SFH 5711 Light Sensors

18 May 2009 Sensors

After I successfully shed some light its time to see some light. For this you normally use photo diodes, photo transistors or photo resistors. But there are two nice little detectors which I came across, special enough to post them here:

The Osram SFH 3710 and SFH 5711. Both are photo diodes respectively transistors adapted to [...]

Low Voltage RGB LED

9 May 2009 Tinkering

Most of my parts want a 3.3V voltage supply. Most of my projects relay on a single coin cell battery at 3V. But driving an RGB LED from 3V is no fun at all. Lets take for example a nice strong RGB LED like the Osram LRTB G6TG – the green channel runs at 3.2V, [...]

Space Invaders Button

13 April 2009 Projects

The reason I started all this microcontroller stuff was that I wanted to create an animated button displaying space invaders characters. Preferably the same size as an normal button (the ones you put on your jacket, not your panel). Now here it is:
If you do not see the electronics for this small display read [...]

Gravitron

23 December 2008 Projects

Playing around with gravity:

A basic piece exploring interaction with gravity. It is (again) half a ping pong ball. On the rim there is a red dot, which always stays up. You can turn it as you want – the red dot will go up again. Video after the click.

How was your day, darling?

1 October 2008 Projects

After some previous testings I did finish the final Version of How was you day, darling? – or shorter “hwydd”:

It is a small object (actually half a ping pong ball), interacting with its owner and environment (and being pretty boring without interaction). The object permanently aggregates light samples (i.e. it measures the every second and [...]

How was your day: The first prototype

25 August 2008 Projects

After the first idea was born a project name and prototype was created:
The project name “How was your day, darling?” or shortly “hwydd” refers to the interaction of the device. After you come home you take it in your hand and the device tells you how its day has been. A neat little reactive device.
As [...]
