I've been using my brewpi to great success for about a year now, but have recently come across an issue I've not seen before. During my current fermentation there seem to have been a couple of strange changes in behaviour, where the temperature fluctuations around the target temperature suddenly...

I've not cleared them, but I've only used 10% of the card. Yeah, that's my thinking exactly. It was ramping up to 18 when it failed, and the temperature was being held at 16.3 by the arduino when I found that there was an issue. When I restarted the pi, the arduino instantly updated the...

I do start a new brew each time, yes. The arduino hasn't been powered down for quite some time, so that is worth a go. I should add though that as best as I can tell the arduino has continued to control temperature even during the logging downtime that has occurred. Still, I'll give everything...

Hi guys I followed the advice in this thread (and day_trippr's excellent LCD thread) and built my brewpi earlier this year. It has been performing beautifully ever since, until recently I have run into an issue. It seems that something is going wrong with brewpi script on a very...

I'll have to do some experiments to determine the answer to this.

Hi Bigdaddyale. Just tried to PM you and got the message "Bigdaddyale has chosen not to receive private messages or may not be allowed to receive private messages. Therefore you may not send your message to him/her."

Just to add to the scramble mystery, I was experiencing them with my initial build which had the SainSmart 2 channel relay and a shift register based LCD. I have just updated the box to use two SSRs instead of the relay, and I am still getting scrambles after the relays switch.

Right, I have everything in a project box and running. Has been keeping some water at temperature for 24 hours now. But, of course, I now have the scrambling issue. Not sure what caused it as it happened overnight. I've read the whole thread (I think) so I have some ideas and things to check. I...

There is a lesson in all of this. When frustrated and tired, go to bed and come back the next day. I was running wires from the IO headers to the shift register, but there were a couple of obvious mistakes in my wiring that fresh eyes saw immediately. That seems to have sorted both issues, and...

Hi all again I got everything working including the rotary encoder and the backlight dimming with a PNP transistor. I've now tried to move everything from the breadboard onto the protoshield. I'll admit I'm not the finest at soldering, but I think I got all the basics for the LCD done. However...

Thanks ame. I've ordered some 2N3906.

Hi guys First of all, just want to say a massive thanks to day_trippr and fuzze for all the work they've put into the brewpi resources on this site. They are invaluable resources for putting this stuff together. I recently got my build working on a breadboard with the lcd. I'm looking to...
