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 is hard to decode, complicated an takes up a lot of space. And then there is JSON. JSON is an easy and efficient way to transfer data. A complex data structure can for example represented as
{
"name": "Jack (\"Bee\") Nimble",
"format": {
"type": "rect",
"width": 1920,
"height": 1080,
"interlace": false,
"frame rate": 24
}
}
aJson is an Arduino library to enable JSON processing with Arduino. It easily enables you to decode, create, manipulate and encode JSON directly from and to data structures. By this you don’t have to bother with data encoding and decoding – this will hand aJson for you. It is based on the cJSON implementation, reduced in size and removing one or two features.

Auf zur Palo Altonale! Zusammen mit Tinkerlog, Palo Altona und Interactive Matter bietet die Good School einen Kurs zu Physical Computing & Tinkering in Hamburg an. Ziel des Workshop ist es Kreativen in 2 Tagen die Umsetzung von interaktiven Physical-Computing-Projekten auf Basis von Arduino zu vermitteln.Wer immer schon mal interaktive, elektronische Spielereien selber basteln wollte ist bei uns bestens aufgehoben.
Wir geben nicht nur eine Einführung in die Programmierung mit Arduino sondern helfen jedem ein eigenes kleines Projekt umszusetzen! Jeder Teilnehmer erhält einen Arduino mit Netzwerkverbindung, notwendige Bauteile und Sensoren. Grundkentnisse sind eigentlich keine erforderlich (OK, Computer bedienen istsollte drin sein). Wer dann schon mal eine Programmiersprache gesehen hat (ActionScript, JavaScript, oder was auch immer) kann mitmachen. Wer denkt er könne keinen Arduino programmieren wird eines Besseren belehrt.
Der Workshop findet am 29. & 30.10.2010 statt. Weitere Informationen gibt es bei der Good School oder Facebook. Wer Interesse hat innerhalb des Workshops spezielle Themen umzusetzen will (MIDI, Robotik, …) meldet sich frühzeitig bei der Good School – dann können wir darauf gerne eingehen.
And now for the English description …

You all know the Blinken Button Kit (aka Space Invaders Button). One of the biggest flaws of this kit is that it is not really a beginners kit. But with the help of Jeff (really big thanks for that) I was able to convert it to a perfect SMT beginners kit. The design was drastically simplified to make it easy to solder, while maintaining the original functionality.

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 documented over at Palo Altona (mostly in German). Some updates will be posted here too.
If this weekend is successful the good boys and girls at Good School will have a nice functional MakerBot Cupcake CNC (probably the first in Hamburg) and I am looking forward to it!
SkatePOV brings POV to your skate board. It is a minified version of MiniPOV2 attachable to your skateboard. Draw texts while skating!
The LEDs pulse to write the text. By moving the skateboard (aka skating) the blinking is converted into a matrix and the blinking becomes the text. This is the first project in a series to bring more effects to your skate board.
