[FONT="]Hi All,
I am new to this forum so I though I would share my build as it goes along in case others have input or would like to share their knowledge.
I have only done 3 extract brews so far and this will be my first attempt to build an all grain setup.
Limitations:
Cheap. I want it all cheap. :-) [/FONT]
[FONT="]Control software to be done in Java and reusable. I am trying to learn this language so this is an ideal opportunity to put it into practice.
[/FONT]
[FONT="]
[/FONT]
[FONT="]NOTE: If i did not already have the Raspberry PI and wanted to learn Java I would just use the standard Home brew heater controls. They are only around 25 quid and I have spent more than that in SD cards and wires.

[FONT="]Plan:
Plastic 30 Liter HTL, mash Tun and Kettle.
2.2KW electric elements. 4 of from ASDA kettles 5 pounds each
Control via Raspberry Pi âArdu Fruit break out board with 240V 10Amp Relays. [/FONT]
[FONT="]Written small reuse java modules.

[FONT="]This is a 25 Liter plastic fermenting bucket with 2 2.2KW kettle elements.
[/FONT]
The elements are installed in the bottom.

[FONT="]Tutorial from to setup the temp probes. All on Raspberry P07 input[/FONT]

[FONT="]Raspberry P02 use for output to MOSFET Circuit with 12V coil 240 V 10amp relay. This relay has 3 10 AMP Circuit[/FONT]

[/FONT]
[FONT="]Software Built so far:[/FONT]
[FONT="]Turn Replay on (for testing)[/FONT]
[FONT="]Turn replay off (for testing)[/FONT]
[FONT="]Get Temp to file (for checking the current temp to screen)[/FONT]
[FONT="]Monitor Temp (For longer term monitoring. )[/FONT]
[FONT="]Control set tempt to hold and for how long. This is the main control that will be used most of the time.[/FONT]
[FONT="] [/FONT]
[FONT="]Testing heating.[/FONT]
[FONT="]Water start temp 36.312[/FONT]
[FONT="]End temp 99.312[/FONT]
[FONT="]Time taken = 30 minutes[/FONT]
[FONT="] [/FONT]
[FONT="]Based off this result the actual output of heat look more like 3.80 KWs. [/FONT]
[FONT="] [/FONT]
[FONT="]Next steps: I am currently monitoring the cooling to be able to fine tune to the heating cycles for the temperature hold.
[/FONT]
[FONT="] [/FONT]
I now have a short 7 day break then i will be building more.
