Rupriikki Media Museum

Sunday, October 14th, 2012

Rupriikki Media Museum opened their new exhibition Jokapäiväinen mediamme (Our Daily Media) on October 4, 2012. For the past year, I’ve been working on three interactive installations for the exhibition. The approach for designing the installations was Media Archaeological or Interface Archaeological. We used old technologies and interfaces – such as the telegraph, analog photography, rotary dial telephones – as the interfaces for providing digital content and user experiences for the visitors.

I would like to thank the staff of Rupriikki for inviting me to work on this project. The whole process was a collaboration with the museum. I would especially like to thank researchers Niklas Nylund and Outi Penninkangas, and exhibiton designer Elina Rantasaari. And of course the construction and technical crew who built the exhibition.

Pimiö [The Darkroom]

The first installation I would like to talk about is the Darkroom. Film photography and darkrooms are far from obsolete, but still the whole process of developing you photographs in a darkroom might be quite unfamiliar for the generation that has only used digital cameras. This installation uses the gestures and artefacts found in a real darkroom as the way to interact with the installation.

The visitor places an empty photograph paper into the developing tray and a picture appears on the paper. The picture then turns into a slideshow of other photographs of the same theme. There are currently five different papers and each paper is going to display different photographs from the Photo Archives of Tampere Museums.

The whole interaction experience is not very accurate compared to all the steps you need to do in a real darkroom, but is enough to trigger the memories of a real darkroom for anyone who has ever worked in one. Or it could inspire someone to get into analog photography. It also does what it is meant to do, which is to serve as an interface for browsing historical photographs.

Technical stuff: Each paper has an RFID tagembedded into it and the RFID reader under the developing tray recognizes each paper and displays the correct content. The reader is attached to an Arduino Uno board and Quartz Composer is used to display the projected images.

Sähkötyschat [Telegraph Chat]

There are two telegraph keys in different locations in the exhibition. The visitors can send messages from one location to the other with morse code. The display shows the message that you are writing and also the incoming telegram sent from someone from the other side of the room.

I started working on this in January 2012. A couple of weeks after that, I saw the Tworse Key project by Martin Kaltenbrunner. (Other Telegraph + Arduino projects exist too). Since he had done the work of converting morse code to text on the Arduino and released the source with a CC license, I decided to not reinvent the wheel and based my code on that. In accordance with the license (cc-by-sa), I will release the source as soon as I clean it up a bit.

Technical stuff: Arduino + Quartz Composer. One Mac Mini controlled both of the locations.

Haloo? [Hello?]

The third installation is a simple phone that allows the visitor to call various numbers from the past and present, such as Neiti Aika (Miss Time/Speaking Clock service) or Juho Holmstén-Heiniö, an inventor from Tampere.

Månsteri Store Now Open

Wednesday, April 13th, 2011

Now you can get your daily Arduino and sensor fix from me, your friendly neighborhood pusher man!

Månsteri Store

Månsteri Store is a place where you can get Arduino boards in its many varieties, sensors, basic electronic components, prototyping tools and much much more for your interactive art projects. Currently, I have distribution agreements with Arduino and SparkFun, but there might be some others in the near future. I try to only stock items that I have personally used and found to be useful in my own projects, but feel free to send me an email if you would like to get some specific stuff that is not on the website.

I already thought about doing this back in 2007 when I first started messing with the Arduino. Back then there were no Finnish Arduino distributors around and not so many elsewhere in Europe either. I couldn’t do it then, but the idea was stuck in my head.

Fast forward to 2011 and suddenly I have the resources to do it, so I thought: “Why not? It’s not like I’m working part-time at the university, doing dozens of art and design projects and trying to finish my MA studies at the same time. I have plenty of time to run an online store!”

For those who don’t know me personally, that is exactly what I’m doing + trying to have an actual life on top of that. Sometimes my stupidity surprises me…

Anyway, it’s been fun for the first few days since the store opened and the feedback has been great. A big thank you to all those supporting me! So head over to http://store.mansteri.com/ and shop til your voltage drops.

Månsteri Store is also on Facebook.

Made in Iron 2

Wednesday, December 8th, 2010

Update on the Iron project. Not perfect but it’s starting to sound pretty decent. Listen through proper speakers or headphones to hear the full effect of the bass.

Mixmaster 1200

Friday, April 3rd, 2009

The second installment of my Mixed Up series has now seen the light. Let me introduce you to the Mixmaster 1200.

mixed up

The Mixmaster 1200 is a wireless scratching device for the turntablist who prefers to deliver his/her scratches like a 5 star chef. As you can see, the Mixmaster does not have any beaters attached to it. This is because it has small laser powered plasma emitter beaters that actually heat up the airwaves around the device itself producing the unique sounding aural explosions.

Beat Blender Preview

Wednesday, March 18th, 2009

Have you ever wondered what a banana mixed with a strawberry sounds like? Or how about kiwi-watermelon puree? Watch this video and you will find out.

I found this old blender from a flea market and noticed that the names of the different blending modes are very similar to the terminology used in DJing. So I decided to turn this kitchen appliance into a DJ mixer.

The audio tracks are triggered by inserting different fruits into the blender. The buttons on the front panel control the mixing modes and you also have two different types of transformer switches for cutting the sound in and out.

The options are:

  • Stir
  • Puree
  • Whip
  • Grate
  • Mix
  • Chop
  • Grind
  • Blend
  • Liquefy
  • Frappé

How does it work?

  • Arduino for brains
  • RFID reader
  • Different kinds of fruits made out of felt
  • RFID tags inside the fruits
  • Max/MSP for converting the serial data to MIDI
  • Ableton Live for playback
  • Mad skills to pay the bills

Stay tuned for more information, pictures and and better quality videos. This is just a preview, I´m hoping to improve it in the following weeks.

I also need to come up with a better name for this thing. Please leave your suggestions in the comments.

Tooniversity

Saturday, December 13th, 2008

Not many people know this, but Concordia University in Montréal also has a toon department deep inside the maze that is known as the EV building. The university officials would prefer to keep this knowledge as a secret, since the brutal self torture that goes on inside the faculty would shock many people. In the same way that the Average Joe or Jane does not want to know where the meat inside his/her burger comes from, no-one really wants to know the shocking truth about the stories behind your Saturday morning dose of laughter.


Tooniversity from Matti Niinimäki on Vimeo.

When watching cartoons, people rarely think about the amount of time and dedication the cartoon characters spend on perfecting their sketches and routines. Unfortunately, consumers love to see toons getting hurt. There is just something special about dropping heavy anvils on the heads of unsuspecting cartoon characters that appeals to the majority of viewers.

Like in all fields of entertainment, the competition in the cartoon business is also very harsh. You are only as good as your last fall from a huge cliff. That´s why all the aspiring cartoon students at tooniversities across the world practice new and inventive ways of getting themselves hurt.

A group of activists from PETT (People for the Ethical Treatment of Toons) have been able to sneak a spy camera inside the Tooniversity facilities at Concordia University. Because of their brave action, all the dirty secrets inside the Tooniversity will be exposed. Please go to http://tooniversity.originalhamsters.com
to find more information and sign a petition to stop this madness.

This project was made at Concordia University for Vincent Leclerc´s Tangible Media and Physical Computing class. You can find technical details from my class website

Arduino & Quartz Composer

Sunday, November 16th, 2008

Here is a quick solution on how to get the analog inputs from an Arduino into Quartz Composer. For now, this only supports the analog values. Reading the digital input pins is not hard to implement, but I still haven´t decided what is the best way to do that.

Sending serial data from QC to Arduino is a little bit trickier, but I will definitely try to work on that also.

What do you need for this to work?

Mickey Mann

Monday, November 10th, 2008

I´m really interested in stereoscopy, which you might have guessed, if you´ve ever seen me running around with my View-Master camera. In my opinion, View-Master is still a superior method for viewing stereoscopic images, but it´s only still images. That´s why I wanted to see if I could improve the design and make an interactive View-Master for animations.

This little hybrid between Mickey Mouse and Steve Mann enables you to control and view stereoscopic animations that are animated in real-time.

It´s an old View-Master viewer modified to have ChromaDepth lenses, some custom buttons, accelerometer, bluetooth radio and an Arduino to control it all. I thought about hiding the electronics with bigger ears, but decided not to, because I like the ghetto-cyborg look he´s got going on there.

So how does it work? You look through the viewer to the screen where you will see some 3-layer Månsteri-action in all of its stereoscopic glory. The great thing about ChromaDepth stereoscopy is that it works with basic colors. You dont need two channels for the video to achieve a 3D-effect. On a dark background, everything that is blue will appear to be in the background and everything that is red will appear to be in the foreground. Colors in the spectrum between blue and red will appear to be somewhere in the middle. If you didn´t understand my explanation, look it up on the interwebs.

The accelerometer detects your motion and will move the character on the middle layer, giving the illusion that the character is trying to mimic your movement. You can control the content of the layers with the three buttons on the side of the viewer. Button three controls the background, button two the middle layer and button one controls the foreground. Check out the video and you´ll understand what I mean. If you have ChromaDepth glasses, put them on to see the 3d effect.

The Arduino sends the sensor data and the button states wirelessly via bluetooth to my computer. The information is parsed in Max/MSP, which in turn sends the data as OSC packets to Animata (my favourite software at the moment). Animata then animates everything in real-time and handles the hiding/revealing of different layers.

If you are interested, I have uploaded the Arduino and Max 5 source codes and also the Animata scene. It´s all very specific to my setup, but someone might find it useful. Download the source.
