CNC Petri BioArt, introduction (no build yet)

it occurs to me that i should explain what bioart is, for those who’ve never heard of it

or specifically, what i mean in terms of my project: “bioart” = streaking petri dishes with bacteria the glow (fluoresce or bioluminesce).

people have done it by hand for ages

http://www.biology.pl/bakterie_sw/bac_pict_en.html (this site used for reference for DIY broth too)

and these are the different colors i wanted to use (clearly, it’s end of term so i won’t have time this semester…)

and to use a pen-plotter system (xy axis gantries) + appropriate stepper software to streak petri dishes by computer instead of by hand.

look ma, i’m all lasercutter!

bright enough to light a room / picture (not sure about exposure they used though)

and of course, there’s already CNC bioart (with a 3d printer frameset), on agar with drops of flourescent bacteria

and recently one with lots of different colors:

Steppers
Digikey has product guides that I’d never seen before (thanks mas.863 classmates)

notes to self. ir2125 wants 230 mV min, attiny can source max 40 mA per pin
