I have made the code I have put together on an Arduino Mega available on Github. Uses a 320*480 TFT LCD display. https://github.com/Brewzone/TFTBREW Allows simulation in code to speed up the process of finding the correct Kp Ki and Kd values ahead of brewday.

Below are graphs showing the effect of Kp Ki and Kd on an Arduino Mega Output running the PID Libraries using PWM. I expect there will be no noticeable change using Time Proportional. Figure 0 shows Kp=255 Ki=0 and Kd=0 Figure 8 shows what I found to be the perfect settings for 18L in a 33L...

I have been working on a PID system based on the Arduino PID libraries. Reading all I could on the subject of PWM vs Time Proportional Heating Control I decided to do some comparison runs. I created a simulation routine to save Me having to run the tests in a real world environment. This...

Since the mobile dashboard reported there was an uprade around two weeks ago the service has gone from reasonably good to absolutely awful. This seems to also coincide with the fact that the dongle is now just over 12 months old. I am aware that 3-mobile are pushing their new rolling 1 month...

I tested a backer 2.75kwh kettle element today. The element is the new type from The Heating Element Company. The shroud only screws on 3/4 of a turn without it even being installed into a boiler. To get it to fit a 33L fermenter the fibre washer has to be discarded as it simply won't screw...

Hi, I've visited a local TIG Welding service to discuss having two 100L stock pots TIG welded together. The chap is keen to have a go and I should be taking a couple over to Him on Wednesday to get a price and to hopefully agree for Him to do the required work. I'm hoping to have some photos...

Well I was getting bored and decided to put this together. The various vessels are insulated although this is not shown in these photos. Video of Sparge Arm

Have any of You attended a Brewlabs course? I'm interested to know what size their pilot brewery is particularly their boiler size. BZ

One of My customers has kindly allowed Me to use photos of His first brewday. Here they are below:

After 2 years of brewing anything between 10 and 20 gallons at a time I've decided I want to do smaller batches like in the old days. As there were no 33L Nordic pots around at the time I went for a 19L stockpot brewery. I should be able to get a cornies worth out of it which suits Me atm...
