Thanks both of you Paul and bperrybap for clearing this up, I appreciate it! I will browse the develper list to update myself on the situation and what the prospects looking like. I will also wait patiently, am I adamant the specs will be awesome smiley
2  Development / Suggestions for the Arduino Project / Re: Arduino 1.5.x -serie is running ahead of 1.0.x on: November 02, 2013, 06:38:25 pm
Is 1.0.x obsolete, or does it still have useful features on its side?

Well, 1.0.x is called stable, and 1.5.x is called beta, so the status of a recommended stable release that 1.0.x has on it's side. I cannot evaluate the program if this really is the case, but it is a significant thing. I wouldn't want to think that of the two versions one if unstable beta and the other one is obsolete (well there is also the fork for the new Intel x86 -thing). Maybe i'm just oldfashioned, but typically software has a stable release plus possibly multiple development branches.

Does anyone have a clue when the 1.5.x might possibly acquire stable state? I know Arduino is expanding and growing, and that's awesome smiley The 1.0.x -serie has been getting updates as well, but at some point i would assume it would be a good idea to start thinking of the 1.5.x as the recommended one, what do you think?

Does the LED blink too? smiley

Hehe no, not at this point smiley. I've now got a couple of ATTiny85s, I thought i could glue one on this one and make it blink.

This is Twitter-style content, but i just wanted to share my fandom and show this silly Arduino miniature with a LED I made out of Hama beads:

5  Products / The Arduino Starter Kit / Just a thank you for the amazing Arduino Starter Kit on: November 01, 2013, 03:00:40 pm
Hi,

I just want to thanks for the Arduino Starter Kit, it is very good... and also beautiful smiley I got the kit as a present from myself, and it's wonderful. The 15 project curriculum is well thouht of, and the set of components gives a nice horizon of possibilities for all sorts of projects. About the same time as i got the kit, i attended a weekend basic course on basic electronics (V=IR, U=U1+U2, resistors, capacitors, LEDs, diodes, the breadboard etc.) at Helsinki Hacklab.

I really appreciate the Starter Kit smiley

Oops now i noticed the forum Website and Forum., I should've posted there instead. I cannot move this thread over there myself, can i?

Here is the difference as told by Github, the home of the code.

The same seems to also happen with the Linux 32bit nightly build as well. Is the site acting up, or data transmission problems somewhere between Tampere and Arduino.cc?

Ciao

It seems the 1.5.x beta -serie of the Arduino IDE is gaining more and more distance from the stable 1.0.x -serie, and 1.5 supports several whole new Arduino products even. I wonder what kind of talks there have been to have the stable serie catch up with the developments?

Best wishes
10  Using Arduino / Installation & Troubleshooting / Downloading Arduino 1.5.4 Linux 32bit aborts before finishing on: November 01, 2013, 02:05:20 pm
Hi there. I'm thought i would like to try out the beta-version 1.5.4 of the Arduino IDE, since Ubuntu only provides the stable version (1.0.5 at the moment). However, from the download page on Arduino.cc -website, the file arduino-1.5.4-linux32.tgz starts to load, but unfortunately aborts on a receive failure 'Connection reset by peer' before finishing.

Is there somewhere where i could file bugs/isseus for the website?

How come you're not using a transistor ?  You can make it fade out nicely then!

Did you refer to me? Because i want to learn this stuff smiley Transistors will come later  smiley-cool

See the attached schematic.

You short the supply into the capacitor - add a small value resistor in series with the
switch if you want to avoid welding it shut and resetting the Arduino!

Oh, so it's not good to let caps suck in energy as they please, without controlling it? As explained f.ex. here. Hmm i guess (V=IR) if at the beginning time t0 the voltage jumps to 5V, the resistance is (theoretical) 0, then the current is infinite, until the capasitor starts to build resitance as it's charge increases. Is this it?

Thanks MarkT for bringing this to my attention!

I love these little electronics and Arduino, it's such a great way to get (back) into math and so many other wonderful things smiley
13  Community / Workshops and Events / "Aeolian artifacts – Pulsar Kites intervention", Tallinn 22.-24.8.2013 on: August 22, 2013, 08:55:07 am
Is anybody attending this workshop+performance called 'Aeolian artifacts – Pulsar Kites intervention' in Tallinn, starting right about now? As far as i understand, it's about augmenting kites with sensors, Arduinos and XBees, and using them as musical instruments with Pure Data.



From the website:

Overview

Aeolian artifacts is a collaborative workshop/working group to build wind-driven sonic artifacts.

This event aims to create an installation of sonic objects which respond to wind force to produce sound. These sonic objects will combine electronic and mechanical techniques, each offering different possibilities of expression and dynamics to consider.

The sonic intervention will occur in an open space in Tallinn, as a performance/installation where the participants will present their resulting instruments to create an improvised soundscape driven by wind.

The foundation of the workshop is based on the Pulsar Kite project by current Ptarmigan artist-in-residence Juan Duarte, which combines physical computing and real-time sound processing. In order to explore innovative ways to develop this idea, it is encouraged to deconstruct this working principle to find alternative methods of interaction with the networks of sensors and objects that can integrate to the Aeolian instruments context.

And

Objective

The result aims to combine both instruments in a intervention / performance based on the sound sources: two kinds of kites, both 1) physical modulators (hardware/software means), and 2) mechanical sound generators (whistling or rattling mechanisms).

You can see Juan's website for some more description of the Pulsar Kites, and videos of them in action.

Personally, i already signed up for the workshop and prepared to travel from Helsinki to Tallinn, but unfortunately had to cancel  smiley-cry smiley-cry smiley-cry
14  Using Arduino / Interfacing w/ Software on the Computer / See this PureData (Pd) instrument with input from an LDR controlled 555 on: August 21, 2013, 04:27:40 pm
Hi, i made a simple musical (erhem) instument with Pure Data (aka. Pd). I also built an electronics component of it, which is a 555 timer chip, who's blinking is responds to the ambient lighting conditions.

An light-dependant-resistor (LDR) controls the blinking behaviour of the 555, an Arduino reads the chip (there is also a LED as an indicator), and sends it over serial to Pure Data's comport -object. The Pd instruments uses the pulse data to modulate a sine-wave oscillator. A sawtooth oscillator is mixed in for a good measure.

Here is a little video



The Arduino code is as simple as

Code:
const int inputPin = A0;

void setup() {
  pinMode(inputPin, INPUT);
  Serial.begin(9600);
}

void loop() {
  int v;
  v = analogRead(inputPin);
  Serial.write(v);
  delay(10);
}

The circuit schematic is too far away, but let me guess :
The capacitor is in parallel with the LED.
The switch is in parallel with the LED.
The resistor is not used.

@AmbiLobe: Do you mean how my circuit was built? The resistor was used; the cap is in parellel with LED and the resistor, which are in series together. See the attached schematic.
