I probably just need to buy my SSRs from auberin from now on. Since I've had a lot of bad luck with the foteks I've been getting from amazon and eBay.
Here's the schematic that I've used.What's the part numbers for the new parts you added to the schematic. Also can you post the pinout of your shift register.
I appreciate you helping. I have tried to get my lcd up and running a few times now. But all I get is an lcd that lights up with the 1st and 3rd lines with solid blocks.
+1They still drop 0.3 to 0.7 volts across them depending on if they're silicon or germanium, etc.
FWIW - This is what I'm using on my BrewPi - http://www.ebay.com/itm/5V-Two-2-Ch...345?pt=LH_DefaultDomain_0&hash=item2a26055221
But I'm only trying to control one chamber too.
Ok, I'll play: this magical relay has no points?I bet your wrong. I'm working with a 20 year old kenmore stand up that has a starting capacitor controlled by a non-0 crossing timer relay. And the compressor still makes this loud crunching sound when when it starts up.
Just a note, the web code for the brewpi in Ubuntu needs to go in /var/www/html, not just /var/www.I'm about ready to give up.
I removed my linux partitions and reinstalled Ubuntu, which worked better than Debian the last time I tried.
I installed brewpi and everything looked ok. When I opened up the web page, I get 404 Not Found. I tried reinstalling brewpi and removing it and reinstalling, but nothing works. I'm not sure what I did wrong.
Sorry, the non-0 crossing thing didn't register.Do you understand what non-0 crossing relay is basically it's never really off. So it doesn't arc when it makes contact.
If the timer that enables the "safety relay" has elapsed before the thermostat calls for "cold", what does the controlling element look like then? Another SCR up stream? Bulb and capillary controlled switch?By safety relay I mean the timer that keeps the fridge from coming on right away. Some have it some don't.
From what I've read it appears they're exactly like an SSR, with the addition of the detector. How could a mechanical relay close at exactly the instant that current isn't flowing in a 60hz line?Well, a non-zero crossing relay is like a normal mechanical relay (not like an SSR).[...]
During the summer, after I get the initial temperature down, I prechill the water to get it down that last bit. I use an old immersion chiller that I place in a bucket of ice to bring the water temp down.

Set your PID Maximum in your Settings to like 25F. As long as you never set your beer below 25F you should be fine. This allows your fridge to chill faster in these situations, as by default i think its 10 or 15F. This controls how big the difference between your fridge and beer temp can ever be. So if your beer was 80, it would have only kept the fridge at 70F, when it got to 79 it would have dropped the fridge temp to 69 etc...but if you set PID Max to 25F it would have been at 80F and dropped your fridge to 55F..larger delta allows faster cooling.So, I've been so busy at work for the past several weeks that I couldn't get motivated to brew for a long time, but I finally brewed my first batch using my BrewPi setup and everything is going great. Thanks again to everyone who helped me get it up and running.
Quick question. I use an immersion chiller to cool the wort, and usually it can cool it down to 70 no problem. But it's been crazy hot here lately, and since my temp sensors are really accurate now, this batch was 80 degrees when I pitched the yeast. My refrigerator took about 12 hours to get it down to 63 degrees.
Should I cool my carboys down to 63 in the fridge before pitching the yeast the next time? What do you guys do?
