stc1000 hack..

[Fil]

If you use an stc1000 for fermentation temperature control you may be interested in this hack to expand the features of the device to include..

NEW Features

* Both Fahrenheit and Celsius versions

* Up to 6 profiles with up to 10 setpoints.

* Each setpoint can be held for 1-999 hours (i.e. up to ~41 days).

* Oversampling and filtering of temperature

* Somewhat intuitive menus for configuring

* Separate delay settings for cooling and heating

* Configurable hysteresis (allowable temp swing)

* User definable alarm when temperature is out of or within range

* Optionally use a second temperature input (fridge air temp) to limit over/undershoot.

* Optionally use approximative linear ramping between setpoints

* Button acceleration, for frustrationless programming by buttons


All the info can be found via http://hackaday.com/2014/03/15/temperat ... e-upgrade/

basically you need the version 1.0 of the stc1000, this hack wont work with ver 1.1
and basic soldering skills to add a 5 pin header or a very steady hand to hold in place during the flash, and ardunio and some wire to connect up.

i took a punt on an ebay stc1000 it arrived this morning and is indeed a version 1

and it is now an upgraded fermentation controller..

This looks interesting. I wonder if you really need the stc1000, Arduinos are powerful little things and I am sure if you can hack these things you could build your own temp controller from scratch. I was thinking of building a web controlled fermentation fridge using one. Why? Because I want to see if I can:)

keep us upto date with your progress.. this is just a simple upgrade for a £15 controller which takes 10 mins to set up and program - no debuggung (fingers crossed ..) tho u do need an arduino to do it,, im working on my own arduino project at the moment too that however is a much slower job
