We had a solid, but uncrowded open house last night, complete with all the usual unstructured goings-on and a side order of semi-structured activities.

Two "Bacterial Cellulose Bioreactors"

Adam Korshid, UArts Industrial Design alum and local “kombuchaneer” stopped by to share some Acetobacter Xylinum cultures and give Pez’s microbial cellulose operation a re-boot.  We were joined by local artist and 915 building neighbor Ann Saintpeter.  We mixed up two 44″ by 18″ trays with a special “blanco cellulose” medium in the form of sugar, yeast and apple-cider vinegar. To prepare the medium we used a rigorous, proven methodology that is generally referred to in the relevant scientific literature as TLAR (“that looks about right”) and verified our efforts using the TTAR2 methodology (“that tastes about right, too”) — as if we know what constitutes A. Xylinum’s standards of delciousness.  Then we turned the bacteria loose in the pond to do their thing.  We’ll deliver the resulting paper to Ann to see if it has a place in her art.

Chris and Brendan pop the hood on an Epson 7700 in need of TLC

Ann also donated an Epson 7700 that needs some TLC.   We spent some time working on it, and learned a thing or two.  For example, we learned how to reset the counter on the maintenance tank (yay, $60 unnecessary expense avoided) and also tried to clear the black ink line by “replacing” the cartridge (boo, $50 unnecessary expense incurred when the printer apparently rejected our “spent” ink cartridge for good).  We’ll re-flash those ink cartridges and show the printer who’s boss — and the printer is well worth the effort involved in rescue.

Dan and some-guy-whose-name-i-didnt-catch were off in a corner working on developing something using some framework whose-name-i-didnt-catch.  Maybe Dan will edit this part.

And Monday’s MMM workshop — Great Success — we had five or six fresh faces and it seemed that a good time was had by all.  We were prepared with lecture materials, if needed, but everyone in attendance seemed to be in a loosely structured kind of mood — so loose, in fact, that we didn’t bother to take a single picture.  PJ has suggested a Halloween theme for the next workshop, and we’ll probably prepare some reading and code snippets in advance on things like LEDs (charlie-plexing, POV and the like)  and maybe some schematics and code involving upcycling old CD drives into creepy animatronics.
