aJson – Handle JSON with Arduino

14 August 2010 Tinkering
Thumbnail image for aJson – Handle JSON with Arduino

Exchanging data with other computers can be a daunting task with Arduino. No matter if you just want to pass some information to Processing, to a Web Service or something else – You always have to encode the data and decode the answer. There always have been solutions like XML for structured data. But XML [...]

Developing Software for the Atmel AVR with AVR-Eclipse

22 July 2010 Tinkering
Thumbnail image for Developing Software for the Atmel AVR with AVR-Eclipse

Developing software – or better firmware – for the Atmel AVR can be quite easy or quite complicated. A lot of people like to just use vi, some source files and a make file. Here at Interactive Matter we are a tad lazy and want a fully fledged IDE, with code completion, one click building, [...]

Palo Altona will build Hamburg’s first Makerbot

9 April 2010 Tinkering
MaerBot Cupcake CNC by Bre Petis

Palo Altona is happy to announce that we will build the first MakerBot Cupcake CNC in Hamburg (at least according to Google). Good School approached Alex of Tinkerlog, me and Palo Altona in general, if we want to help to build their MakerBot. And yes we are happy to help. The weekend project will be [...]

Die deutsche Version gibt es nach dem Klick (und dann weiter unten). This time it is all non-technical (technically not – but that starts to get complicated). To further encourage tinkering in Hamburg, Alex and I have established a regularly tinker drinkup every Thursday (nearly) at Saal II. Currently it is a very cosy drinkup, [...]

Filtering Sensor Data with a Kalman Filter

18 December 2009 Tinkering
Thumbnail image for Filtering Sensor Data with a Kalman Filter

Some days ago I wrote about noise with a LIS302DL accelerometer. There is obviously something wrong with my hardware. But before I get a new version out I need to implement some software filtering. After some unsuccessful results with low pass filters I choose the Kalman Filter. The Kalman Filter involves an awful lot of [...]

Decoupling LIS302DL – There I fixed it!

15 December 2009 Tinkering

As you probably know, I really like I2C sensors and especially the LIS302DL. But adding this accelerometer to your circuit is not as straight forward as I thought. But in the end I got it quite right. It all started out with a 0.1µF ceramic capacitor. For good measure I put a ferrite bead in [...]

Driving Circuits from a CR2032 Lithium Coin Cell

Thumbnail image for Driving Circuits from a CR2032 Lithium Coin Cell

Just another good example of ‘lesson learned’. I often use the very common CR2032 coin cell batteries to drive my circuits. Small, cheap, easy to get and there is a quite a range of good and cheap battery holders. But recently I have tested an complete over the top design which pushed the poor little [...]

In my ongoing series about cool sensors Interactive Matter presents the AD7746 capacity sensor: What is a capacity sensor good for? You can of course make a device to identify small capacitance (up to 4pF) but that’s boring. Much more interesting is how it reacts to touching. Read on how to connect it to the [...]

Doing business with makepcb.com

Trying a new board house is always an adventure. Of course I use BatchPCB for small scale prototyping. But for an upcoming project I needed some higher quantity of boards for a cheaper price. So some ‘real’ board house must be found. There are so many options, that I do not try to list all [...]

As a effect of the Space Invaders Button I learned a lot about all those LED Matrix projects on the net. As a roundup I collected a short overview of all the different projects I found.

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 [...]

Low Voltage RGB LED

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, [...]

Some days ago I searched for an small USB-based AVR programmer. After some research I stumbled over an new old friend. The AvrUsb500 SMD from tuxgraphics.org: To make it short: It is a bit pricey but exactly what I was looking for. But read the full review after the click.
