Hi to all,
you can find updates about our projects on the news section of our wiki 
pages

shorter news for the experimental incubator at the news section 
dedicated to it

Prototypes running, PCB preparations, water kefir project 6/7/2014

Lets start from the end, shall we? We have started to work on a 
development of growing media which will make tibicos (water kefir) 
grains grow well increasing their size and weight and produce tasty 
beverage. More info can be found here under the granos tibicos growing 
media project. We have also uploaded two new manuals, one for culturing 
Tempeh and second for nattō, the later is till in development.

Concerning the incubators, they are being further tested. In both 
Marcel's and my case the cooling is still an issue, there were several 
problems with the peltiers which should be noted - some of the modules 
broke down. Marcel suggests to use for CPU designed water cooling system 
on the hot side of the peltier. In my case Algoldor I've been making 
nattō heating up to 42-43°C for over 32 hours, all going well but I've 
to report that the heatsink got really hot, bit dangerous I would say 
with my current establishment, I should rebuild the heating/cooling unit 
enclosure and anyone who is ready to go to build their prototype should 
really keep the high levels of heat in mind, be safe!
At the moment we are preparing for the PCB version of 2.2 mamut tamna. 
When Arnd is back from his holiday we hope to progress. I'm thinking 
about talking to the people from the Seeedstudio in China, Shenzhen if 
they would be interested in helping with the PCB prototype finalization 
and hopefully after debugging put it online to their store as a kit. 
Anyway we will see about it, it is as long distance run :-)

That would be all for now, so the plan for the next month and a bit is 
to get more people into the granos tibicos/water kefir growing media 
project, improving the nattō manual and concerning the incubator work on 
the cooling of the peltiers and progressing on designing of the PCB 
prototype of 2.2 mamut tamna.

Busy times sounds like, right?

Sincerely,

FAA
