with driptray

the original shelves were solid plastic with about a 1/2 inch gap at the back so I traced around one for the wooden shelf. I have almost finished the drip tray and then I'll give it a go cheers steve

didn't want to drill a hole in the door so I put the tap on the inside. marine ply with 4 coats of an outdoor varnish. I need to add a drip tray and there is room for a second tap. cheers steve

Malted if you need help loading the code, bonj or me can help, just let me know. About the filter plates, you don't need very small holes if you are using a filter mesh as well, my top plate has slots over 1cm wide, it holds the mesh in place very well. cheers steve

I haven't tried or even looked at the autotune so I don't know about it but the PID beta 6 library looks like a better library to me, the brewtroller uses it for its PID. here http://www.mediafire.com/view/?9ewpb6mib64nbvk is the spreadsheet that I put together to have a play with pids, its not...

I have spent a lot of time playing with the pid library but I just went with the original one and turned it on 5 degs to go which reduces the amount of Ki wind-up but if you look at the PID beta 6 library...

I have a spare PCB that I was putting aside for my own use but you can have it, PM me your details. You will have to source all the parts yourself as I don't have any left. cheers steve

there is 4 digital I/O left (0,1,12,13) and 2 analog pins left (A4, A5), A4 and A5 are the I2C pins so you can use them to expand or just use the extra digital I/O's to do what you want. cheers steve

are you talking about a Plate chiller or a cold plate just to clarify

Yeah there are 2 different pin outs for the 2n2222a, which is really annoying

Sure you can do that, the unit is set up with a PID window size that is adjustable between 500 and 5000 ms and can be set in the "unit parameters". If the 5 second window is too small then you can change the code here void unit_set (void) { int param[] ={...

it's funny because they are aware of the approval numbers as they mention it on this Heating pad page good luck to them, it looks well made and safe, just hope some idiot doesn't do anything stupid with it and ends up hurting someone. cheers steve

Hey HSV the connector was mentioned HERE or you could get the ones from modtronix and mount them on the other side. I used a 10K pot but originally designed it for a 5k pot doesn't really matter which one you use both will work. That Arduino you linked is correct. cheers steve

Your Right mate Approval of electrical articles- department of fair trading I would say its a declarable artical (point 8 page 9) so therefore its againts the law to sell such an item without an approval number on it. personally I'm not too fussed but they should be carefull. cheers steve

Top job there Paul, looks awesome cheers steve

Hey dave, in github if you click on the history button at the top right of the code it will show the history of the changes that have been committed, for each change there is a button on the right that is filled with numbers and letters, click on that and it will show you the changes, the last...

to change the pump and the timing start, it is in the pump rest function void pump_rest (int stage) { if (stage==9){ pumpRest = false; if (Temp_c<94.0) digitalWrite(Pump,HIGH); else digitalWrite(Pump,LOW); if (Temp_c >= 95)tempReached = true; } else{ pumptempError =...

here is the fix for the hop additions CODE I haven't changed the boil temp but I can if there is a demand for it cheers steve

Hey Bigbanko, it was set at 98 because that is the temp I found that gave me a nice rolling boil, I found that the DS18B20 was reading 1.5 degs under my spirit thermometer at boil but was the same temp up until about 80 degs (the datasheet says its accurate up to +80 degs). The hop additions...
