Prosjekt: Postapokalyptisk redesign

Konseptet er å sy humoristiske/pønkete one-off applikasjoner lagd av gjenbrukstekstiler, gjerne over reklameprodukter donert fra store firma som har bestilt mer enn de trenger.

Her er noen kreasjoner.

Ideas for Drawing machine #1

My my how time flies. It’s been two years since I built my first drawing machine, a vertical pen plotter. I’ve since then built two more machines using the same hardware, but different sizes, and made over a hundred drawings and experiements. I even had a one month exibition at a tiny local cafe. Nerd goes artsy.

Currently all three machines as broken, partly from transportation, partly after an “inventors day” at Vitensenteret last year where the kids where a bit too “hands one”, if you know what I mean :) So they’ve been in the basement gathering dust, waiting for inspiration to strike.

Most of the images I’ve drawn on the machines have been based on SVG input, and quite a few have gone through Illustrators scribble effect before printing, converting filled areas into continous lines. I loved the effekt, but sort of lost my moxy. It felt that the machines should be used for something more fun than just drawing the images I gave them. At least the end result might excite ME more. Here is an example of a “scribbled” vector image:

There are so many things I want to do. I’ve been tinkering with computer generated art off and on for years, and I’ve researched complex ideas based on machine vision and artificial intelligence. One idea I’m brewing on is converting input from webcam 1 into paths, and then use machine learning to let the machine itself use webcam 2 to figure out how to control the motors to draw a result similar to input (after filtering, simplification or style transfer). I’d love to take the drawing machines in that direction, but I think I want to go back to basics a little bit first. My first drawings where simple done by giving the two stepper motors commands on rotation individually, and the patterns that came out where just lovely, flowing and organic, repeating infinitely.

Example arduino code:
void setup() /****** SETUP: RUNS ONCE ******/
stepper1.moveTo(4048); // 2048 = 1 revolution

stepper2.moveTo(-2448); // 2048 = 1 revolution minus 400 to make it asymetric asymetric

}//–(end setup )—

This is what came out when using a sponge and ink:

Love it!

So I’m thinking of going back to exploring more random and serendipitous ideas. One direction could be a simple “random walk”, as explained in the introduction to the book “The nature of code“, by Daniel Shiffman. Alongside Conway’s Game of life, the random walk is one of the classic beginner examples in generative visual computer art.

Here is an simple example of a picture drawn by random walk-code:

I love the randomness, but also the order that comes from the fact that there are strict and simple rules to be followed. The next point on the path can only be forwards, backwards, up or down one pixel.

Go to my codepen to see the code and to generate your own.

Leave the random walk running for a while longer gave me this.

So I think I’ll try that.

Or perhaps an etch-a-sketch :)

Update: Find a route beween vertices.

Kosmorama inviterte til å holde gjenbruksverksted under årets filmfestival. Temaet var dinosaurer og monster. Masse unger (og voksne) var innom for å lage fine ting.

#30 White IPA

Jeg fortsetter min eksperimentering med hveteølgjæret WB-06,denne gangen med en utforskning av den nye yberhipsteraktige ølsorten White IPA, altså en kombinasjon av et balansert banany hveteøl og en humleleken IPA.

#29: Brunweizen

Bryggedag 12.02.2017. Biab.

Utskriftsvennlig oppskrift

Jeg fortsetter min litt skranglete ferd gjennom bryggeland, denne gangen styrt i retningen av en hveteøl. Den første allgrain-ølen jeg brygget var faktisk en hefeweizen, basert på en oppskrift jeg fikk fra kjernekaren Børge Barlindhaug, men siden har jeg ikke forsøkt meg på denne stilen.

Det var litt tilfeldig at det ble hveteøl, men for en stund siden fikk jeg 500g (!) med utgått Safbrew WP06, og den måtte jo brukes til noe. Selv om datoen var passert så kunne jeg kompensere for evt dårlig gjærhelse ved å øke mengden litt, samt lage gjærstarter for å sjekke formeringsevnen til våre små venner.


#28: Luganighetta stout

Luganighetta er navnet på en vidunderlig spiralformet ferskpølse, opprinnelig fra Lugano i Sveits, smakssatt med en varmende kryddermiks bestående av blant annet kanel og koriander. Min variant av pølsen har også nellikspiker, muskat og sort pepper. Krydderblandingen gir pølsene et litt “julete” preg, og ble inspirasjonen til denne winter-warmeren, som bare blir bedre og bedre med tiden.

Kunst Knust – salgsustilling på Kafé Soil / Taps

I hele januar 2017 henger noen av bildene mine på koselige Kafé Soil / Taps på Bakklandet i Trondheim. Ta turen for en chilikaffe eller håndtverksøl. De fleste bildene er tegnet med min selvbygde tegnemaskin.

DIY: Homemade drawing charcoal

I wanted to test using drawing charcoal with my drawing machines, and decided to try to make my own instead of buying from eBay.

Charcoal is made by burning (cooking?) wood in an oxygen-starved environment.

I took a tea-leaf tin (bought in Tokyo many years ago, sad to see it go), and punched a small hole in the lid. For my first test I used cuttings from a blackcurrant bush that has been left to dry outside for a few seasons. I looked for fairly straight pieces, cut them with garden shears to fit in the thin, and put the lid on. In the evening, I made a fire in the wood stove, and placed the tin in the flames. I just left it there until the next morning.

The result turned out really great, and I especially liked that all the fine delicate details of the twigs stayed intact, even most of the bark stayed in place. I was also surprised that none of the twigs snapped. Even the thinnest came out perfect!

What’s next? You can see my first test drawing towards the bottom of this page, and I’ll update this page with other drawings later. I’m especially looking forward to testing charcoal made from different trees and shrubs, to see if there are differences.

Update: If you are an artist and want to test my charcoals I’d be happy to send you some. Send an email to morten.skogly@gmail.com. I’d love to get your feedback on how they work compared to commercial drawing charcoals.

Idea: Mad Max RC car

Idéa / Work in process:

I was gifted this solid radio controlled car wreck after Maker Fair Trondheim 2016. It pays to have a rumor as a hoarder :)

The engine top is cracked, and one wheel is missing, but the rest of the car seems to be intact, and the frame seems to be really well made.

Some years ago I made an “art car” with my kids from a large pink Barbie toy car that was destined for the trash-bin. This time I watn to make a running, radio controlled art car.

Being a huge fan of post-apocalyptic themes, I’m thinking of making this into a dangerous looking wehicle the could fit right into the set of Mad Max.

I did some Googling and came across this hazardous looking car:

Now, I don’t want a car that only looks dangerous. 

I want the car to be fricking dangerous!

 So no rubber spikes or decals with nuclear waste symbols. Just real, nasty, rusty nails and junk, placed to cause maximum damage if it crashes into you (or explodes). And perhaps a tiny coil gun cannon, or a grinder of some kind, or a flame thrower?

This is going to be awesome!

Bonus features: 

  1. Autonomy with arduino. If you move, it will hunt you :)
  2. Long range fpv. 4 km?
  3. Run the engine on methane.
  4. Frickin lasers!

Some other cars for inspiration:

Nice blades
