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?
Progressing on the incubator etc. 12/6/2014
Hi to all,
we have done more testing on the experimental incubator prototype 2.1 mamut, in this case Marcel and me Algoldor, you can see updates here
At the moment the major issues are improving the cooling and getting h-bridge which would allow for a simple switching between cooling and heating.
I'm also working on the blog post about the Food Hacking Base and Dancing_Drops 2014 Europe winter tour. It goes slowly and I would definitely like to add your impressions, you can do so here on our draft
We have done also bit of updates on our wiki in general and we are keeping the Facebook group quite busy, occasionally posting to the discuss lists.
Anyway thanks for your attention and have a good time!
Blog post about FHB activities at 30c3 is up! 19/3/2014
Hi to all, this is just a short echo, the blog post about our activities at 30c3 is finally up on our WordPress blog
Having more photos next time would be lovely :-) We can still edit and add stories of course.
Talk to you soon,
Experimental Incubator Mailing list created!
we have a new mailing list dedicated especially to the experimental incubator project. Many thanks to Steffen who made it happen!
If you like to subscribe please send an email to
and confirm your request when you receive the "confirmation email".
Welcome to this communication media, I will post more tomorrow when I hope most of us are in, but if you could start to think about recapitulating what you have done so far on the variety to this topic related project and summarize it that would be lovely :-)
Sincerely from Jeju,
PS Please let know the people who you think should know about it, thanks!
