+Turns a Raspberry Pi into a cheap, universal & web-enabled kiln Controller.
-Of course, since it is basically just a robot sensing temperature and controlling
+Forked from the reflow oven project: [picoReflow](https://apollo.open-resource.org/mission:resources:picoreflow) which I found through a blog post on [succulent ceramics](http://succulentceramics.com/2016/10/07/wifiraspberry-kiln-controller/)
-environmental agitators (heating/cooling) you can use it as inspiration / basis
+
-when you're in need of a PID based temperature controller for your project.
+I used this to add a firing schedule control to a little pottery kiln I picked up second hand. The kiln is 10A/240V rated to 1000 degrees C. It had a door switch and a basic thermostat which allowed for 25%, 50%, 75% or 100% power but no timer. With the kilnController I can now set it up for a bisque or low temerature glaze firing and leave it to its own devices, checking progress every now and then on my mobile phone or PC.

-  * MAX 31855/6675 Cold-Junction K-Type Thermocouple
+  * [MAX 31855](https://www.adafruit.com/product/269) Cold-Junction K-Type Thermocouple (about $6 on eBay)
-  * GPIO driven Solid-State-Relays/MOSFETs
+  * [K-Type Thermocouple Sensor](https://www.google.com/search?q=K-Type+Thermocouple+Sensor+1250+1M+SY+site%3Aebay.com.au) -100°C to 1250°C ($3 on eBay)
