I have one of these that I'm monitoring CO2 pressure with: https://www.amazon.com/gp/product/B01I81QKWE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I have it mounted in a tee on a manifold. It would be simple enough to screw it into the fitting that is with your spunding valve. You can...

One reason might be if you were using a 3V micro controller (ESP32, Grand Central, etc) and the SSR you have didn't reliably turn on for a 3V input. In that case you might need a level shifting circuit up to a higher voltage. That could be done with a transistor and a resistor, however that...

ESP32 Flow Meter Update: I tried all eight of the counter inputs in the new FW rev and confirmed that they were working fine using the flow meters I listed above. I used a 27K resistor to GND as the divider (with the top resistor being the 10k pull up in the flow sensor). All of the counters...

I had thought about using something like an LT1635 op-amp + reference chip to generate a stable reference voltage for the AREF pin rather than using the supply (still might). Then I could use one of the inputs as a monitor for what VCC (and other power rails) is doing. If VCC is tied to AREF...

Awesome, I've got the stuff install and will run some test cases tomorrow.

More than enough for me.

That would be awesome, thanks!

I need four counters, so I need all of them to work. Have you guys considered doing firmware variants that have different options (I know, that would be a big headache). So if someone had flow sensors in a keg fridge and had 6 kegs, they could do it without needing 2 controllers? Not that 2...

To expand on what I found a little using the flow meter and GPIO2 on an ESP32, the flow meter I'm using has a weak pull up (10k) and a strong pull down (35ohms) as its logic output. Therefore, the onboard 10kOhm pull down in the ESP32 won't allow for the pin to ever go to full scale which...

Thanks BrunDog, I'll get in there and update them. For future enclosures, I'm going to have to remember to keep an access port for the USB interface to the micro. On a separate note, I got some ESP32 DevKit v1 boards to replace the problematic ESP8266 configuration I was using. To people...

If I have interfaces (a MEGA and an esp8266) that have v43 firmware on them, and they aren't particularly easy to get to (bad design on my part!), is there a compelling reason to dig them out and upgrade them to v45?

I'm using these for keg volume monitoring. I don't use the counter directly, but have a global that is updated by a script to show the current volume and then hide the actual counter. I also have a "reset" button that resets the counter and the keg volume to 20L. For the rate, I'm going to...

In the scripting language, is there a way to perform more than one operation on a line? I was trying to do some math and it wasn't working, but I realized that it was ignoring anything more than one operation per script line. For example: new value x new value y x = 2 y = 1 + x / 2 returns y...

EDIT: Deleted

I can't wait to play with the new stuff. In the new v45 firmware for the ESP8266, is the counter issue that existed for GPIO0 fixed? I am starting to make a controller for my keg fridge and need 4 counter channels. I can use a MEGA or an ESP8266, and I'de rather use the latter if I can...

When I first set it up, I had set the grid to be pretty fine and had forgotten about it. I had it set at 5x5 in a 1920x1080 screen. If I change it up to 20 or 30 it made it much more reasonable. I think that is plenty sufficient. Thanks!

Not to jump on the feature creep bandwagon, but I have noticed one thing that seems like it would be relatively simple and helpful for people building work spaces. In the appearance tab for an element, it would be very useful to have the width/height as a text entry. I've been making some...

I have seen this behavior on my 8266 as well (just polling the A/D, 1-wire, and a counter). I thought it was due to power disturbances from the USB power brick, or little ESDs when I touched it or something. Usually, when it gets into that state if I reboot the 8266 it starts behaving itself...

Reading through the few pages since last time I was here, I saw a comment on 4-20mA transmitters, but none suggested. I'm going to try out some of these: http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&toolid=10001&campid=5338413729&icep_item=142280471283 which take 0-5V in and...

I really like the new look. Does the top menu hide (like the windows bar) or did you just clip it out of the screen shot?
