Nema refs are starting to require 20amp sockets but most houses have 15amp sockets on 20 amp breakers, and really there isn't much difference in the US between the sockets or what they can handle…

Because you could design it so it all fits behind the lcd and it'll be an all-in-one form factor. a micro could also be used but they are a bit more of a pain to program and not that much smaller than the nano

How hard would it be to change the design of the board so it will interface directly with a nano?

What I find that works best, (I use carboys in a fridge. with heat wrap) is to put the beer probe in a thermowell inside the liquid and then put the fridge probe under the heatwrap (reptile tape) against the side of the carboy. No insulation on the outside of my carboys just the reptile tape...

Heat wraps work just fine. it's all about probe placement, the pid will figure out the rest

In the grand scheme of things it won't really matter. if you're cold crashing at 2 in the morning then you have bigger problems to deal with….

Brace yourself… "Somethings wrong in my logs" posts are coming…

Bring 5v to ssr+ and ssr- to corresponding arduino pins for heating and cooling

Found this info online, don't know if it'll help you though Step 3 - Device Tree settings as below: Add device tree to /boot/config.txt to disable the Raspberry Pi 3 bluetooth. sudo nano /boot/config.txt Add at the end of the file *if you want to change the blutooth to miniuart port(bad)...

Are you using a pi3? because that port would be for the uart that is now attached to the onboard bluetooth. maybe try ttys0 or ttyserial0

You sure you don't have a ch340 USB chip? you might have to use ttyUSB0

It's important if you want to forgo an potential errors going forward that anytime you use a pc that you set it up from the beginning with the default user pi. once you get that part down you will have very few issues with the setup process. I setup my virtual machines this way when I was...

^This. I imagine he would prefer to operate a single control algorithm to handle all functions. sounds kinda like he wants to mitigate support tickets down to a handful of potential troubleshooting methods. I don't really see how it's any different, functionally, than the old system. other...

I found encoders already attached to breakout boards on eBay a while back I think the seller was alice1101983

Hope u have a backup of your sd card. sounds like the power failure borked your card.

Soldering looks good, but all your resistors are backwards…… jk lol

That's assuming that your pi isn't dumping power into the built in wifi and BT. and also the new cpu consumes much more power than before, hence the necessity for 2.5a or better power supplies. Considering you can't reliably run a pi3 on anything less than 2.5amp that would immediately throw...

Hmm so I guess back when we all addressed this issue and found the pi to be lacking in power to handle 3-4 arduinos at once and found the powered USB hub to be a great solution and it all eventually led to bringing the bt option into play for multiple chambers isn't enough for me to be confident...

The problem you are having is boiled down to the high powered pi3 trying to power 3 arduinos at once. you need to get a powered USB hub. and definitely use the serial number approach by using symlinks as addressed earlier

Kegimatic hasn't been updated in just as long, had way less features and no support. if you guys can get an archive of the raspints site I'll throw it up on one of my many sites that I don't really use.
