Atari Punk Console

Here is a little sound toy i made a while back. its basically a pair of 555 timers that both live in the same chip (the 556 package) that oscillate, syncing the start of the first o the second. hehe sounds complicated, well this is the sound it actually makes:

here is a small map of the connections and controlls:

And here is flickr user «dnny» beautiful tutorial on assembling the contents in what is known as freeform:

The «synth» inside is a common little thing and is known as the Atari Punk Console, or as its inventor  Forrest Mims originaly called it «Stepped Tone Generator»

Review of Captain Credible concert in the «Hitra Frøya» online paper

Nice little mention of the school concert at Fillan:

Snipped from the webpage

«- Dette er lyden av en mann og hans data-arsenal. Med en gammel Nintendo som trommemaskin og låttitler som «Golden Spaceship» kan ingen beskylde Captain Credibles nerdeelektronika for manglende originalitet. Liveshowet hans skal visstnok være noe helt spesielt også, skrev musikkpressen før Captain Credible spilte på Bylarm i 2009. Der vakte han oppsikt – det samme skjedde da den høyst særegne artisten hadde konsert for 160 elever på ungdomstrinnet ved Fillan skole torsdag

Captain Credible kom med humor, hjemmebygde rytmebokser, instrumenter, video-mixer, dukker som spiller med spisepinner – altså lys og lyd så det holder – så det ble en forrykende konsert. I tillegg fikk både elever og lærere testet engelsk-kunnskapen under showet, som er en del av Den kulturelle skolesekken.»

Next Life

Somebody asked told me at a concert today that they like metal and retro 8-bit music, but they hadn’t heard of Next Life. So for him, and any body else who hasn’t heard of them, here:

If you want to check them out even harder, here is the URL to that via:

Otherwise things are running pretty smoothly on our Sør-Trøndelag tour so far. Robin, my insanely awesome and very strong sound technician has started a blogg where he complains about me, amongst other things:

YOLO!

DIY visual metronome

Diy MIDI visual metronome / cue from Captain Credible on Vimeo.

 

This is a box i made for Petter Vågan of the fjords. It is a box that basically will blink one set of LEDs if it recieves a MIDI note creater than C3 and another set of LEDs if it recieves a note equal to or lower than C3. It is meant to be used as a metronome or as a visual cue. The idea being that you set up a MIDI track in you sequencer that will send notes to the led so you can see the tempo/beat without it having to make any sound.

To make this i used a couple of transistors to switch the power on and of for the LEDs. and an Arduino to recieve the MIDI and turn the transistors on and off.

 

here is a crude drawing/schematic of the circuit:

Schematic

 

In the above schematic i have of course left out the circuitry to make the atmega work. if you are wondering how to do that, then look here.

 

I am on tour right now and the arduino code that i wrote for this is at gome, but ill post it as below as soon as i get the chance.

p.s. you will need Francois Bests awesome MIDI library for the arduino to make this work. http://playground.arduino.cc/Main/MIDILibrary

I Wish I Could Talk – Sound installation

 

I am fascinated by the wonderflly organic sounding chaos you can get by letting something like a flickering candle controll sound. This is one of my art installations that i originally made during the audition for the Oslo academy of fine arts. The entire piece is sentered around a single candle and it is the candles flickering intensity that controls every aspect of the sound and behaviour of the sculpture. A feedback circuit involving a fan that kicks in when the system feels the candle has burned too hot for too long keeps the installation in a lifelike loop. It will use the fan to play with the flame more and more violently until it is afraid that it may have extinguished it. Occasionally it does accidentally extinguish its candle, in wich case it goes in to a complainong state calling out for help in hope that somebody will light the flame again.

More info on the piece will be available here:

DIY plate reverb

 

This guy has made a beautifuyl d.i.y. plate reverb unit in his basement. this is basically a sheet of metal with a speaker attached to it and some contact microphones also attached to pick up the sound as it reverberates in the sheet of metal. Pretty easy to make.

Wonderful documentation and a step by step instruction set on how to make your own can be found here:

Make your own vst plugins

vst

I have recieved a lot of questions asking how to make your own VST plugins like the ones on this page http://www

.captaincredible.com/VSTplugins.html.

First of all for those of you that don’t know what VST plugins are this is what wikipedia says:

«VST (Virtual Studio Technology) is an interface for integrating software audiosynthersizers and effectplugins with audio editors and hard-disk recording systems

In effect, they are little bits of software, effects and synthesizers that can be used within a Digital Audio Workstation (or DAW for short). A DAW is what we call software that is for making and mixing music.  The format (VST) was invented by the company «Steinberg»  in 1996.

If you are a hardcore Hacker, then you will probably want to write VST plugins as C code and compile it to a dll file. But if you’re like me and you’re eager to experiment with sound and get things churned out rather than spend hours writing code then you are in luck. There are at least 2 «easy to use» visual programming tools for to make vsts with. They are «Synth Edit» (on left) and «Synth Maker» (right)

These two are pretty much the same, but synthmaker looks a little more blinged out. Both have demo versions that you can download from their webpage, and while both will export to VST plugins, synthmaker will also create executable files.

 

Despite this, I prefer to use Synthedit and I will be putting together a tiny tutorial very soon.

in the mean time, download the demos and play around why dont you.

Helmetdance Sound Installation

Helmet

 

This is the Heletdance Sound Installation. It uses an old bicycle helmet, the accelerometer torn from a counterfeit wii nunchuck, an atmega328 and 4 pillars with speakers and halogen lights and a bunch of diy electronics including a MIDI to Relay box that i will be sharing the build of on the instruction pages soon.

The helmet is to be worn by a participant. The 4 pillars emit sound and flashes of light in responce to the participants actions, and the sounds and flashes that are generated relate directly to the orientation and velocity of the head of the participant.  The participant is rewarded for high velocity abrupt head movements, and thus is coexed into excerting oneself further and pushing the boundaries of ones trapezious muscle and other muscles in the neck. This effect is further emphasized when there is a crowd of observers for whom the participant may feel a need to perform and or impress.

Violent head movements, combined with loud unpredictable noises and sudden bright flashes of light, also lead to a sensation of spacial confusion and dizzines and seems in some cases to make the participant less aware of his/her surroundings and more in touch with his/her own performance and interaction with the piece.

The piece has been exhibited twice, at Kunstakademiet in Oslo, and at Podium, also in Oslo.
