At the moment the most up to date info is at the top of the page, have fun!

Experimental Incubator 30c3 talk video recording

Here is a link to our talk on "Open source experimental incubator build up", call for participation which we gave with Arnd (and with support of Lars) at 30c3. It covers the topic more or less, well have a look if you like

"Production" code uploaded to Github 4/2/2014

A new version has been uploaded to the github which has basic functionality: heat to temp, cool to temp, keep at temp; show time elapsed.

Button function: SELECT resets time; LEFT steps through the modes; UP and DOWN change target temperature; RIGHT stores the settings in EEPROM, so the program will continue after a powerdip.

Here is the link to the code which is now uploaded to the Github

thanks to Lars and others from WarpZone for sharing and of course Arnd for the coding.

At the moment the code allows to measure temperature directly after switching on the Arduino, nice and simple. Not sure what else it is ready to do. Next step should be setting up switching the peltier heater on through relay, 39-43C would be fine.

Prototype tested in TechInc 12/1/2014

Here is short youtube video where we tested the Experimental Incubator prototypes which we put together during the same evening in TechInc, many thanks to Arnd for supervision and help!

What pins belong to what (before 1/2014)

Here is just a link to the info which Arnd made in preparation for 30c3, you can clearly see what pins are doing what

Under Arnd's supervision I was able to do all the necessary soldering by myself, putting together therefore one functional prototype, testing it later - it was doable.
