1 wire uses open drain to avoid bus contention. It wont work without the pull-up resistor.

Yes I still have both. The hop spider can be shortened easily. There is a giant hose clamp that holds the screen to the top of the spider.

There is a mix of 0603 and 0402 for the resistors and capaitors. It's all configured through stuff options for what components get soldered down. No jumpers or dip switches for configurability. I will be using 3 of these in my control panels and all 3 will be configured differently.

PCBs are here. Starting to assemble the ethernet section on one. Doing the hand assembly at work since we have microscopes at all of our solder stations.

I really like the fact that I can heat up cleaning water in the HLT while I am boiling in the BK. Would be great to incorporate into Brucontrol so others can take advantage of this.

The next device I am looking to add uses Bluetooth, so the esp8266 nodeMCU wont work. I modified the original code for the esp32. To do so change the #include <> at the top as shown below, as well as the changes in the second screenshot above and inside the setup() function. Everything else...

I've been using this circuit for 7+ years without any issues. These are low voltage, low current FETs driving the inputs to SSRs. Neither the BCS nor Brucontrol support this digitally, so that's never been option.

Here is a better schematic of this circuit. IO43 is used to select which other output 41 or 42 has priority over the other.

Here are the specs for the circuit board. All the options are based off of what components are soldered to the board. Its not reconfigurable without soldering. 1. Wiznet W5500 SPI Ethernet based off of Arduino Ethernet Shield 2 2. All analog inputs can be configured for 0-5V, 4-20mA, or...

I might be willing to part with one. Let's see how everything turns out first

And off to the fab she goes. Should see 5 of these back by the end of next week.

I you are looking for something "better", take a look at Brucontrol. It is pretty much limitless with what you can do with it. I even wrote FW for the nodeMCU to add devices that are not natively supported. And with the HTTP data exchange interface you can tie this into all sorts of other things...

Playing around with making an ethernet/screw terminal shield/carrier for the mega. Got a ways to go...

The tilt uses the CR123A battery. The last company I worked for, we designed these batteries into all of our wireless products. I have done ass loads of battery draining testing of these batteries. Since it is a lithium battery it's voltage stays "relatively" constant throughout it's life so you...

I use Brucontrol so that uses a sql database for data storage. I typically brew 5 gallon batches, but do an occasional 10 gallon batch.

So between the 2 panels, here are all the features. I have 3 arduino megas that have all but one analog input used. 39 12V relays for ball valves and solenoid valves 8 proportional valves 4 DPDT relay board for the large electronic butterfly valves 4 channel SSR board for AC pump control 4...

Finished up the low voltage panel.

Mounted the front panel of the low voltage panel today

5+ years ago I used a RIMS tube. Mounted it on the MT as you are looking to do. No issues with it.
