This page is dedicated to Food Hacking Base (fhb) presence at '''39c3 Power Cycles''' in Hamburg, Germany, from 27th till 30th of December 2024.

==[[38c3_crowdsourcing|Crowdsourcing Campaign]]==

Please have a look and support [[39c3_crowdsourcing|our crowdfunding campaign]]!

===Location/Contact===
The approximate location of our assembly has been unofficially confirmed to be more or less like the last year.We will know soon more.

You can call us on our dect phone, tFHB (8342).

===Goals===
Meeting each other in the real world a noble goal isn't? We got bit of "buzz" at the ccc summer camp 2023 but bit more would be lovely From the material point of view we would like to set up our experimental kitchen and two workshop venues, space may be bit limited this time. We will run workshops, experimental projects and be functioning again as a food, drink and bio related hub for community. Ending around 1000€ in plus would be nice so we are kind of ready for the next event which ever it may be.

===Guidelines===
Over the years “be excellent to each other” is our motto, lets stick to it! Being thoughtful and sensitive towards follow beings around you is important to us, keep them safe from your experimental frenzy and give them your ear when needed. It is a long ride through the life, many experiences therefore to gain and "swarms" of mistakes on the way. Keeping in mind that it is the community which matters and you are it's part is important, be happy :-).

===[[38c3_departments|FHB Departments]]===
We will build and run FHB '''experimental kitchen''' and at least one but rather two '''workshop venues'''. There will be of course the support infrastructure like dish washing area, resting corner, dining area, fhb (and other) projects presentation desk etc.

===[[38c3_workshops|Workshops]]===
Organizing and running food, drink and bio related "workshops" is most likely our main activity and what we share with the community. You are welcome to join either submitted or spontaneous workshops or you can give some, for more information please check this section. Please this time keep an eye on "smells" because of being inside.

===[[38c3_projects|FHB Projects]]===
If you have a special project which you would like to run at/from fhb please let us know! By project we mean something what is happening few to several times during the congress, could be presentations, workshops, tastings, example is for example [[ccccamp_pde| Probiotic Drinks Everywhere project]].

===[[38c3_budget|FHB Budget]]===
This project is funded independently, majority of it being donated by fhb "members" or supporters through our [[37c3_crowdsourcing|Crowdsourcing Campaign]]. We aim to collect 1500€ before the event starts, the total running budget should be within 3500€, for more info check this section. Please do remember our motto "everybody welcome, no one turned away for lack of funds". Donations are much appreciated but voluntary!

===[[38c3_wish_list|FHB Gear, Tools and Ingredients]]===
In this section you can find the info about what the fhb equipment is going to be and importantly also the "wish list" of what we would like to have but we are missing (like a high quality blender, multiple induction stove etc.).

Experimental Incubator/ei prototype designing

[[Image:Experimental_incubator_complete_voidwarranties_1600_022017.jpg|thumb|Working prototypes assembled at VoidWarranties, February 2017]]

Here you can find info about the development of the experimental incubator (ei)current version 4.0 "Just" which we are now working on. There are several improvements compared to the previous version [[3_0_fermento|3.0 Fermento]], the third generation of the experimental incubator.

One of the most visible improvements are the professionally produced PCBs which we had ready at 33c3. Already for second time we have made complete kits, this time we had kits with all parts and also only bare PCBs for the more experienced ones.

=== How to get involved, contact ===

Get your kit. That is the most easy way how to get in and participating. Contact [[User:Algoldor|Algoldor]], [https://wiki.techinc.nl/index.php/User:Justa Justa] or send an email to the [[How_to_get_in_touch|experimental incubator mailing list]]. The total cost is around €35-40. The cost of the components in the kit is around €13, if you can afford to invest €25 (+ postage) that would be nice. Another €8 is for the solid state relay (SSR) and heat sink if you do not have your one already. Shipping should be around €5-10 depending where are do you live. Total around €40 or so.

If you want to get involved, you need help with experimental incubator set up and running or you have some other questions you can get in touch with us:
* at our [[How_to_get_in_touch|experimental incubator mailing list]]
* directly with [[User:Algoldor|Algoldor]] by sending email to algoldor (you know the sign) foodhackingbase.org
* directly with [https://wiki.techinc.nl/index.php/User:Justa Justa]
* pop in our #foodhackingbase channel at oftc network, IRC

=== Soldering and connection ===

For the people who has the 4.0 just version kit (equals v2.1b) we have detailed instructions how to solder, connect and use this version under the '''soldering guide''' shared as a [https://wiki.techinc.nl/index.php/File:Incubator-v21b-solderguide.pdf pdf file] at TechInc wiki's.

=== Schematics ===

This design was made in KiCad.

SVG versions of the schematic and the PCB are provided at the right side.

You can find a [https://wiki.techinc.nl/index.php/File:Experimental-incubator-v2.1.tar.gz tar.gz file] of the combined files here.

For reference, the values for the resistors are:

* R3: 620 - 680
* R4: 1K - 1k
* R5: 3.3K - 3k3 (3k6)

=== Currently Run Prototypes ===

The prototypes which are currently running the "just" version are listed here:
* [[experimental_incubator_just_la_cherche]], person coordinating [[User:Algoldor|Algoldor]]

=== Temperature probes ===
The DS18B20 temperature probes used have PVC shielding; that makes them unsuitable for long time use at temperatures of 100°C or above, although the sensor works up to 125°C. Some sensors are shielded with PTFE cable (more commonly known as Teflon) which is considered food safe to 160°C, so these sensors can be used up to 125°C (max sensor range). Here are some ordering options:

=== Bugs&Issues ===

* Displayed Time Error - Reported on 12/3/2017 by [[User:Algoldor|Algoldor]]. If the incubator is in the off function displaying only time, after several days the display stops showing "time" but starts to show variety of symbols without meaning. It seems like after the amount of the time displayed is too much for the display it crashes.

=== Soldering and connection ===

For the people who has the 4.0 just version kit (equals v2.1b) we have detailed instructions how to solder, connect and use this version under the '''soldering guide''' shared as a [https://wiki.techinc.nl/index.php/File:Incubator-v21b-solderguide.pdf pdf file] at TechInc wiki's.

=== Schematics ===

This design was made in KiCad.

SVG versions of the schematic and the PCB are provided at the right side.

For reference, the values for the resistors are:

* R1: 2K - 2k2
* R2: 330 - 360
* R3: 620 - 680
* R4: 1K - 1k
* R5: 3.3K - 3k3 (3k6)
* R6: 10K - 10k
* R7: 470
* R8: 470

=== Software ===

The software was written by [[User:Bigmac|Bigmac]] and Lars, the code is uploaded [https://github.com/foodhackingbase/incubator on Github here].

=== Currently Run Prototypes ===

The prototypes which are currently running the "just" version are listed here:

=== Temperature probes ===
The DS18B20 temperature probes used have PVC shielding; that makes them unsuitable for long time use at temperatures of 100°C or above, although the sensor works up to 125°C. Some sensors are shielded with PTFE cable (more commonly known as Teflon) which is considered food safe to 160°C, so these sensors can be used up to 125°C (max sensor range). Here are some ordering options:

=== Bugs&Issues ===

* Displayed Time Error - Reported on 12/3/2017 by [[User:Algoldor|Algoldor]]. If the incubator is in the off function displaying only time, after several days the display stops showing "time" but starts to show variety of symbols without meaning. It seems like after the amount of the time displayed is too much for the display it crashes.
