Re-reading this again. I have a jumper-configurable voltage to the Dallas chips. I was planning on running them at 5v anyway. The data line is still at 3v3. I could run that through one the remaining sets of pins on the logic level shifter... better or no benefit? If it is beneficial, then I...

Smoke 'em if you got 'em! LOL Mylo

Disregard my question about running the relay inputs through the logic shifter. I see that the pins are just sunk to ground to activate the emitter in the opto-isolator. In some of the videos available online, I see people are tying the Vcc pin (next to IN2 on the 4 pin header on the relay...

Ok. Just found a schematic for the relay boards. In order to benefit from the opto-isolation, you have to remove the jumper, and connect the JDVcc to 5v. So if I made that relay header 5 pins, and added a 5vdc, I can break it out at the relay board into a 4 pin and a 1 pin header...

Vito's wiki links to a doc that recommends pulling down GPIO15 and pulling up GPIO0 and the reset pin with 10k. The 4.7k is the pull-up for the OneWire data line. I've always seen that value used with the one-wire data line...? Thanks for the feedback. As far as the caps are concerned, are you...

I took some details from Thorrak and others and whipped up a through soldering variant for the people in my home-brew club with a bunch of screw terminals. Also left the RJ45 for installation versatility. Built in the recommended pull-up and pull-down resistors. Finally, broke out the terminals...

I fixed those compliation errors, (and a broken link in the wiki). I guess I'll start submitting PRs. I still can't seem to get the debug, simulate, or emulate flags to do anything appreciable. Everything build now (with the exception of the ESP32). Mylo

Finally got the PlatformIO stuff setup. Starting to play around with the config options. I am not able to turn on DEBUG mode, though. When I do, I get a compilation error on line 46 of the OneWireTempSensor.cpp file: " 'class OneWire' has no member named 'pinNr' ". Maybe the OneWire library has...

I'm not sure what he means here, either, as the i2C is a piggyback board. Maybe if you used a bunch of Dupont wires between the piggyback, you could break out the one pin for the LCD's Vcc and supply it separately from the 3.3 that you send to the backpack header. The jumper on the backpack...

Certainly dry. Dangerously so, this year... However, I'll take a try heat any day over hot and humid. So I see that both you and Thorrak have a "door" pin marked on your boards. I haven't dug through the source code yet - and I don't see anything about it in Vito's Wiki. My assumption is that...

Thanks, Lee. I'm just outside Phoenix in Scottsdale, Arizona. Mylo

Yeah, that would probably work. Again, I am just not sure that it’s worth the additional work - just to have on/off control of the LEDs that illuminate the fridge. Actually, I was just thinking of putting a separate 8266 in the control box and running something like WLED to drive some...

That doesn't seem to have an external antenna. Mylo

I actually have a commercial, glass door fridge that I've completely hacked all the wiring. I have ON-OFF-AUTO switches on the evaporator fan, both sets of lights (top logo, and interior). I also have a ON-OFF override on the compressor. I use the AUTO setting on the interior lights to tie into...

Just discovered this project, and I’m very excited to have a better way to control my fermentation than the STC-1000+! My question today is less about the software than it is about the hardware implementation. Is there a recommendation for the fridge probe? Should it be buffered at all - say in...

Sounds like you flashed it with the “minute” version, instead of the “hour” version. I think there are 4 to 5 versions for diff functionality - logging (comm), hour, min, and one vessel brewing... Mylo

Keeping the dream (thread) alive! I just finished my first successful flashing of an STC-1000. A second one is on the way (slow boat from China). I'm looking to leverage the communications build. I have an extra Particle Photon kicking around that I have already integrated with Dallas one-wires...

I would caution those that think it's a good idea to wrap their chest freezers in wood. While it might look good - most chest freezers work by having their "hot coils" close to the outside skin. Those that have dedicated "evaporator" coils externally (on the back) are the exception. That design...

Everyone is chasing the consistency dragon. Some are better at it than others. Eliminating variability is the key concept there. There are two main factors that contribute to success in brewing. There are recipe issues, and process issues. Let's eliminate the recipe issues first. There are a ton...

What does this mean for somebody putting together a system like this today? Are there some A/C units that have "dual layer" evaporator coils? What do we look for, specifically? How much of a risk is this, ie. how likely is failure? Obviously if the cooler was metal, there is a chance that...
