Another, interesting arduino based step sequencer. 
Very well documented.
People are just harvesting hardly!

as we want to connect 20 buttons, 2 potentiometers
and a 12 scale mode-selector, we need a total of 34 inputs. additionally, we want to control 20 led´s, so we need 20 digital outputs. the arduino has 6 analog inputs and 14 digital inputs/outputs, which is obviously not enough, so we are going to use five 4051 analog multiplexers to multiply our analog inputs and create a total of 40 inputs, and three 595 shift registers to multiply our digital outputs and create a total of 24 outputs.

Code Ready. Wow.

As I read on this blog post by Jose Anes, he has been working on a while on the Arduino > Ethernet shield > Pachube communication, to achieve “a Pachube manual update client on the arduino that pushes EEML XML format to Pachube directly, without a PC in the middle”.

If someone has a better library, please let me know where to find it.  Here is a link to the code I am using to accomplish this purpose.  So far it is working well enough.  Some interesting points:

• I had to print directly to the stream (ethernet in or out), because creating an EEML XML string was too much for the small memory of the Arduino.  Direct writing as a stream solves that.
• I still want to avoid the reset every time it uploads to pachube (took that from the pachube CSV example).

The code: 20100218-pachube

On January 1st, we announced that we’re working towards Arduino 1.0 (for details, see this post). Our goal is to stabilize the platform so that it’s supportable and a good foundation for future developments.

We’ve been getting good feedback from experienced developers through ourdevelopers list; from many users individually, both in person and in email; and in the Arduino forums. We want to make sure we get input from the whole Arduino community. This means we want to hear from users, teachers, designers, developers, tinkerers, distributors, and anyone else who uses Arduino. This means you.

There are a few ways you can let us know what you think:

* Please fill out the the Arduino Uno Punto Zero survey to let us know what you think of the current features of Arduino. It takes about five minutes. Even if you have nothing else to add, this will help give us a broad picture of Arduino use.  Please share this widely with your friends, students, and anyone else you know who uses Arduino.

For those who want to discuss in more depth, there are a few venues:

I thought the guys from Wired made me us look like crazy dudes in the pictures they took of us last year … but that photographer did a nice job compared to the photoshoped version of me coming out on this week’s Metro Teknik, the free paper about technology. The paper is featuring Arduino, and they took a couple of pictures here at my lab at K3. I am glad someone cares about our story and puts it into everyday people’s hands. The article is written in a language that is easy to understand and looks for examples of people working with Arduino at different levels. You can even see a how-to guide around the IDE … not bad at all … if it wasn’t for those pictures that make me look like the guy with the craziest hair-dude in the universe.

From [CamelPunch] Steve is explaning his Brushduino project:
The Problem: 
My daughters don’t brush their teeth long enough, if left to their own devices. When my wife or I brush their teeth, we do a nice thorough job that takes a little while but when the girls do it themselves, they tend to cut it short. Timing them doesn’t help, as they just stand there and chit-chat until the timer goes off. It’s not that they don’t brush their teeth LONG enough, it’s that they don’t brush their teeth WELL enough.

The Solution: 


When you fire it up, it plays the opening bars of the Super Mario Brothers theme song while randomly flashing the white LED’s. Then it starts instructing on what area of the mouth to brush.
Each time a section of the mouth has been brushed sufficiently (stroke count was based on experimentation and dentist recommendations) a few more bars of the Super Mario Brothers theme song is played (along with light show) and then the next white LED starts flashing. It’s easier to see the pattern than it is to describe it. The section they’re supposed to be brushing at any point in time is blinking with the already-brushed portions of the mouth lit fully on.

Check the full post with the code!
Thanks Steve!

Nice Oomlout wat to have a twitter-related typewriter. Arduino (+ethernet shield) searches for a keyword and then physically prints the results for everyone in the office. 
Code ready.

Good work!

Finally a good attempt to make an Arduino Based controller. Steve Cooley is presenting his Beatseqr.
The data is sent to the computer via OSC. Source code for the project is available on github. 
Comment & congratulate on Beatseqr blog for the time and effort.
