I have altered the bonjuino2 code so the pump turns off at 80 deg and also the boil setpoint is 100 deg to ensure the heater remains on 100%, but 98 deg must work if others are using it. I have not tried the modified program hopefully over the next two days on water. I don't have a kaixin pumps...

I am not the best solderer as you can see and I did have some issues where I need to resolder, in fact the reason the screen did not start in an earlier post of mine was because one of the three legs of the pot was not good. I think everethting is oldered OK (not great) as it all works and on...

Lael I have attached some photos if it helps. the big green capacitor is something that Matho recommended in a different post and the red bridge wire you see on the front side of the board was necessary to get the down button to work. I suspect I may have damaged the etched circuit during soldering.

I have completed fititng the box and the soldering is finicking the first time but it all works out even if some re-soldering is required like in my case. That said I still have one problem and the screen still goes funny occasionally when the 240 v pump turns off/on. Matho recommended...

I have found my problem and thanks for all your helpful hints. Once I turned up the brightness using the pot I was able to see the text.

The screen powers up and is bright blue, maybe its too bright so I don't see any text. Is the pot on the back of the screen or is it the one I soldered on the shield?

Its all soldered and ready to be fitted inside the box. I have connect a temp power supply (12v) but have not connected to the relays or temp probe. The screen the LCD screen is the same even when it is removed form the board. I think the ardiuno -uno is OK because I was able to run the sample...

Finally got my act together and soldered up the board and fitted the LED screen and ardiuno -uno. I have not wired in the push buttons yet and thought I would load the program and check all is OK before fitting it all in the box. I upload the program and do not get any errors but the LED screen...

It is a 19 litre BigW pot inside a 50 lt CUB keg

Update on the progress of my new BigW pot. Ran a brew yesterday and all went very well. I did need to throttle the flow on my pump back to avoid the 3 mm top support plate bending. I did stop the pump every 15-30 mins to release the bed and stirred the bed three times. Efficiency was about 78%...

Lael - thanks for all your hard work mine arrived earlier this week

It is difficult to see how it works with the st steel malt tube as a plate hides it. I have attached pics of the plastic bucket system that uses the same principle. The clearance is quite fine minimising and leakage. The malt tube has a false floor (not shown) for the grain bed to sit on.

If I was to put a timer on I would have said to reset every 10 mins, but I am not sure that this is what evetone is doing with their clone's but may be necessary with a bed depth greater than 200mm. Athough there may be leakage at the bottom seal I think it is minimal as the clearance is .25-.5...

As I did not have pictures I thought I would mash 5 kg today and see what effect the recommendations had on the flow rate as well as take some pictures. I heated the water to 40 deg and then mashed in I had good flow at the start which then dies down, if you stop the pump and let the level fall...

Lael - You maybe onto something with the crush. I am using a JSP Malt mill that is not adjustable after checking with the feeler gauges I am at 1.0mm. I am an experienced mash brewer (>50 batches) and have used this mill for a 3V & BIAB (using fine voile) without a problem and have always added...

I have tried a lot of different combinations. I first started with the little brown pump which did not give enough flow, so I added in another 12vdc pump rated at 10l/min which appeared to be OK but the last batch on the weekend used a 240v mag pump. I have tried using voile, 1mm st steel...

Blue Baggers thanks for the feed back. It is good to know the Big W pot should work without an issue as I am also using a 50lt keg as the boiler as well. I have not used the pot as my existing system uses a 250mm pot as the malt tube and I think this has been my problem. a 300 mm pot gives 50%...

I have been working on my clone for the past 2 months and although I have made several batches I am not at a stage where I would walk away and be confident that I will not get a stuck mash or a fountain. After hrs of research here it appears my problem is due to using 5.5 kg of grain in a 19l...

John I also was able to buy a bag at the same price. Do you know if any of the corio brewers used it to make english ales by adding something like munich to give it a more ale type flavour? Doug

Ross, Thanks for the advice. their website states that the 2011 model comes: "This New Model Also Comes With Top Quality American Dorado Taps And Stainless Font Instead Of Chrome Plated Fonts." Would you still advise to purchase without the font and taps Doug
