Hello World,

I put up a 2.5m wide polargraph over the weekend for an exhibition and made a little big experiment with the new polygonizer function 😎
And my second little (sparkfun) servo served me very well! 130.183 polygons and penlifts in approx. 76hrs ! (and the same amount in testing before...

best,

another CMYK experiment with Dullbit's amazing " Death to Sharpie" script! -> http://www.dullbits.com/drawbot/drawbot
still need to fiddle around with the parameters to get better control over the transition zones....but the abstraction is also nice anyway (in my eyes at least 😎 )

original photo is from here: https://repeatingislands.files.wordpress.com/2015/08/lionfish1.jpg

both images drawn with each a new set of Stabilo point 88 pens in CMYK (57, 56, 44, 46)

big fish on A2 "FABRIANO Academia 200g/m²" front side (a bit too rough for Stabilos, will try rear side next time)

small fish on A3 "Zeichen Austria, Edition Dürer Tuscheblätter 200g/m²" front side

PS: little servo still up and running <3

Nice Job , DaniK !!!
I'm working also with color separation and dullbits algorithm using processing .. but not good results by now.

Amazing work DaniK. Will have to work on my gondola design to allow easier swapping of pens.

Thanks guys!

Josep, In case of the fishes, as I am no pro in processing, I just fiddled around for a very long time with the parameters of Dullbits script...the colour splitting I did in Photoshop by simply changing the mode to CMYK and splitting the channels. 😎 I then processed the 4 different greyscale images separately... always looking for a workaround if possible...

krummrey, I started working on a new "plug and play" penholder that clamps the pen automatically...based on Sandy's design...but it doesn't really work yet...need some more iterations...will upload it as soon as I am satisfied with it....
but I anyway only needed to put 4 different pens (that's why I am so obsessed with CMYK lately)...within a total of 34 hrs and 35 mins in case of the A2...so changing a pen for a couple of minutes wouldn't really blow up "printing" time that much... 😉

btw, that's also an interesting design, I think:

It is not that it makes any sense with the colours as my pens are quite obvious, but I did it just because I can 😎
Thank's Josep, very cool design, I love it, very handy to use!
