hi I use the g couplers in south Africa and simply attach the spunding valve to the gas out of the coupler after removing the one way valve and blocking the beer out.

made mine from a faulty chest freezer, had to replace the compressor anyway so turned it on it's end so the compressor was at the top, placed the tap at the front, but not a quick job, also replaced the thermostat with a 12 bit digital controller (bit of overkill but not much available in South...

I have built 4 refrigeration systems having become interested in them due to necessity, nothing large and with the aid of some Danfoss software tools, mainly to calculate the length and size of the capillary tube requirements. first attempt was a kegerator from an old fridge, used a 1/10hp...

I don't know if it is of any help to you as my system is mostly home made built aground a 40lt boiler with a basket spun with a small geared motor from the top and a digital temperature controller, I make 30lt batches and start with 24lt of mash water, generally I use 3.5kg grain coarsely ground...

@pocketmon I had no stability problems at all the readings are stable and consistent, have you got a good signal strength on your Wi-Fi connection? is your common connection solid? a poor common will cause noise and affect your analog, do you have a 0.1 or better ceramic capacitor across your...

my setup is just a very simple remote monitoring of the spunding pressure so I don't need to run to my brew shed all the time, just a quick check to see if all is well. it is a w1219 controller, it is tied in with my heater to prevent overheat conditions, wouldn't want smoke and flames in a...

hi Lee the temperature controller is a small part of my fermentation cupboard, just there to prevent my heater (3 power resistors on a heatsink) from getting too hot the the main controller is of my own making and uses a pic16f866 with an mcp9808 temperature module to control the heater and a...

the pressure sensor is driven by the 5/16 inch gauge output of the spunding valve, the sensors come with a length of clear plastic pipe, to adapt from 5/16 to the small pressure sensor pipe I used 75mm of 1.2mm refrigeration copper capillary pipe and soldered it to 5/16 copper pipe. attached is...

this is the circuit diagram and ESP8266 data sheet

data sheet for the pressure sensor

these are photos of the setup in situ. the feed ours from a spunding valve into a pressure 200kpg (29Psi) transducer which gives out 0.5 to 4.5 volts, this is then reduced to 0.1 to 0.9 volts for the ESP8266 module. the output of the ESP module is 0 to 5 volts via pwm and a filter the system is...

hi Lee you're spot on, never considered github, the code is only an adaption of an ajax server example from the net, when I have time I will duplicate it and post. for the time being I will put a circuit diagram together and a couple of photos and put them on this post.

just wish you had replied a week ago, just had a disaster with my computer, lost my home partition and with it all my programs,stupidly not backed up for a few months, will have to get my program re-written but will take a few weeks as there are a couple of other items to recover first. I will...

welcome to the world of anosmia, have suffered for 13 years, only had any sense of smell when I had a a cortisone injection for a few weeks, I could have burnt in a house fire and never known, no ability to enjoy hops or esters in ale but always found a good craft ale far more enjoyable than a...

I personally have a different approach to getting my temperatures consistent, I get good repeatability and excellent efficiency generally over 90 percent, my system which I have used since the late 70's involves spinning a basket of malt in a full volume mash, to stir the water in an electric...

this is my first post and I would like to give back a little to this forum for all the help it has given me. does anyone else have the same problem as I had? having gone into pressure fermentation and finding it very advantageous I was concerned with monitoring my pressure, my fermentation...

problem being the cold air will fall out the bottom. I have an old freezer and I have tuned it on it's end, would have twisted the compressor so it was upright but found it was faulty anyway so changed it and re-gassed. makes a good spacious kegerator for two 30lt kegs controlled with a cheap...

how is the heat sinking on the device? the triacs do generate quite a bit of heat, this will eventually degrade the device and cause it to fail. I mounted mine on a heatsink with a small fan to cool the SSR, just a cheap 30A device from aliexpress and it is running 4 years so far.

never tried to revive old yeast but my information is that the yeast has a dormant stage and it can take a while for it to reactivate once in this state, not sure it it will return with exactly the same characteristics once reactivate, would be an interesting experiment though to make a starter...

I once had an issue with infections after completion and just before bottling eventually found out it was Candida in my mouth, caused a lot of failures, it is important to remember the mouth is a source of bacteria and yeasts from our foods. make sure your not breathing on your brew at any time.
