I ([[User:Algoldor|Algoldor]]) will give "official" talk on the project of Experimental Incubator build up at [http://events.ccc.de/category/30c3/ 30c3] at the end of December. We need to have some prototyping models present, we will also give a workshop on what we are up to. So for now next step is to make a list (below) and order the parts which we need to build one or two "models/kits" and test them, ordering larger quantity for 30c3, 5-10x. We have around 30 days to take care about all of that, page below is mostly about that.

By the end of April we want to have three to four prototypes running in different locations so we can test in reality the design which we choose to apply. The aim is to measure, display and control temperature, both heating and cooling using the kit which we presented at 30c3, sharing updates through [https://github.com/foodhackingbase/incubator Github]. Next step after few months of testing, reporting on the progress and summarizing of the results will be design of the PCB boards, most likely due at the end of July or during August.

Inspired by my ([[User:Algoldor|Algoldor's]]) friend Arnd I would suggest to go what he explained to me as an "industrial prototyping". Simplified: get well supported and functional parts for bit of extra cash and build up the first functional prototype from them. Afterwards when the prototype is working, start to break it down part by part redesigning them or using another cheaper/more feasible variants shaping the incubator to your like, bringing the costs down. This approach seems to be bit more expensive to start with but it ensures that even less experienced contributors to the project would be able to build their functional experimental machine having than what to work with which I think is crucial.

One of the most important things which we have to decide on is "how do we want to do it?" meaning mostly in this case the practical way of building up a prototype. Below are strategies which we were implementing so far.

Short time goal - 3-4 prototype build up (deadline end of April 2014)

By the end of April we want to have three to four prototypes running in different locations so we can test in reality the design which we choose to apply. The aim is to measure, display and control temperature, both heating and cooling using the kit which we presented at 30c3, sharing updates through Github. Next step after few months of testing, reporting on the progress and summarizing of the results will be design of the PCB boards, most likely due at the end of July or during August.


  • Industrial prototyping

Inspired by my (Algoldor's) friend Arnd we choose to go by "industrial prototyping". Simplified: get well supported and functional parts for bit of extra cash and build up the first functional prototype from them. Afterwards when the prototype is working, start to break it down part by part redesigning them or using another cheaper/more feasible variants shaping the incubator to your like, bringing the costs down. This approach seems to be bit more expensive to start with but it ensures that even less experienced contributors to the project would be able to build their functional experimental machine, having than what to work with which I think is crucial. For more info please check this page created at Techinc hackerspace by Arnd. Till we get a proper PCB design and assembled kit you need to have some certain electronic skills set to get "smoothly involved" in the project. The more easy to put together kit option should be ready for 31c3 in December 2014.
