Here you can find info about the development of the experimental incubator (ei)current version 5.0 "" which we are now working on. There are several improvements compared to the previous version. We are switching for the [https://www.itead.cc/smart-home/sonoff-th.html Sonoff TH16 model] which is the biggest change. 



=== 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 €25 max.

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 ===

Probably not necessary or needs to be updated.

=== Software ===

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

=== Programming ===

You will need a USB to serial (TTL) converter to program the arduino. There are 3 brands of converter chips out there: prolific 210X, FTDI, CH340G each with their own driver issues... [http://kig.re/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html CH340G Drivers for windows and mac] [https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/software-installation-windows PL2303 CP210x drivers for windows]

=== 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.
