I'm not convinced the exact frequency of the PWM matters all that much as long as you're within the khz ballpark. I don't think the manufacturers of these fans wanted to complicated their design by making something that requires decoding/counting/clocking/comparing the exact PWM frequency with...

That different direction appears to be downward.

I'm a big fan of Mycodo running on an rpi 4 for our garden. 5 temperature sensors, 3 humidity sensors, 1 co2 sensor. Controlling 3 channels of PWM (2 fans, 1 light) and various tasmota-flashed AC switches. Also had 4 capacitive soil moisture sensors but those corroded over time. Overkill...

A couple weeks in. Threw in some PCRed buddies I had under the canopy. Getting kind of cramped.

So sticking your penis into someone else without consent is rape, but sticking your finger in without consent either isn't rape? I don't understand the distinction but I guess trumpies desperate to make excuses for him.

Should work, although I'm not intimately familiar with inventronics drivers What will likely happen is that, unable to provide the voltage that your LEDs want to run at 2.1A, the driver will provide them with what it can: 148V. So each cob will get 37.0V. In response to not getting the voltage...

You had one too? Now I know two people who had it on the same day, we should start a club. How much do you remember? I caught parts of the process on the big screen, but mostly don't remember it until I felt them uncork me. That kind of woke me up. PSA get yourself a bidet, makes the process...

The output of the esp32 gpio pin, when outputting a PWM signal, is a square wave, alternating between 0V and a peak of +3.3V based on the duty cycle its set to. If its an arduino device, it'll output a 5V peak signal. These fans require a 10V peak on the input pin for full speed and that's...

Is it really a USB-C plug? That seem like a disaster waiting to happen when someone plugs a charger into the fan or controller, or some other combination. +10V on a random USBC pin might fry something.

Oh, Power Earth, indeed. The blue/brown/G&Y combo is very typical European power color code. Try connecting a multimeter between the FG and GND lines and see if it changes as you change the PWM input?

That's one sexy access door. I wonder what the FG and PE lines are for, I suspect one is for reporting the actual speed of the fan?

ya the cedar frame outside is 26x24". This round had a couple floods in early veg and it was mopey for too long until it picked up. Had to flip earlier than I hoped cuz we're pressed on time.

What do you mean you humans? What color is the sky in your world? :p

Keeping it compact, end of week 6 on a 9-week strain.
