Fourteen months ago, I got a Raspberry Pi (3 b+) and I started on a quest to automate my grow. It was an idea that began as a discussion with a small group of friends at the now defunct Cannabis Culture forum. Topics ranged from the usual temperature and humidity blah blah, to a robotic hand...

I believe in all cases, it's the size of the orifice that you must change. That's the way my tri-fuel generator converts, It came with two orifices, one for NG the other for propane and a single regulator. "The orifice is the hole that is drilled in the orifice plug. This is where the gas...

True, they both come out of the fractional distillation process at the same point, but kerosene has all the constituents of paraffin oil whereas paraffin oil doesn't contain all the constituents of kerosene, therefore you could obtain paraffin oil from the kerosene but not kerosene from paraffin...

Just for fun, I'll disagree on this point. Most references to "Lamp Oil" that I've found are referring to paraffin oil. Paraffin oil is a more refined version of kerosene, not the other way around, id est, one could obtain paraffin oil from the kerosene but not kerosene from the paraffin oil...

Are you thinking one of these? I have one in a garage. It's quick and works well but does have a yellow flame which indicates incomplete combustion. I keep a door or window open, and use a carbon monoxide detector and recommend that one be used with this heater. Also the controls are manual and...

I built a wireless system to automatically water up to 7 plants. After I finished, I found this and though I haven't tried it, If you're interested in DIY and Arduinos, you could start with this kit from Amazon.

Hmmmm... what to do? Just out of curiosity, what type of outer wall, floor, and roof construction, insulation, number of windows/skylights, and as close as you wish to disclose, location. I ask as I once designed tobacco stemeries to fit inside buildings with sawtooth roofs that varied from 20'...

Back to the beginning... very informative article there OldMedUser, thanks for that.

I just finished building a 7 plant automatic watering system for my personal use, here're some pictures, This is the control box with the power supply, fuses, relays, and wifi control (ESP-32S). Not shown are 7 soil moisture sensors attached to a soil control "black" box located in the center...

I have run across ads for fans that have digitally controlled electronically commutated motors such as this one: https://shopgrowlife.com/product/hyper-fan-stealth-8-in-710-cfm/?gclid=Cj0KCQjwt_nmBRD0ARIsAJYs6o0732RkeAPqE3fZM-G6FGnX6jCBdyVtDjJAxDmrWYASBFG7BFzOe68aAuruEALw_wcB But most come with...

One last suggestion, a board I just ran across, is 1 x Wemos® Mega +WiFi R3 ATmega2560+ESP8266 32Mb Memory and can be found here...

Now that I have a better idea of what you have in mind, Take a look at the ESP-32S development board. Many features, much cheaper (~$10 at Amazon, ~$3 at AliExpress), Wifi and Bluetooth built in, programed with the Arduino IDE, etc. I think this might be a better choice than the Wifi Uno and be...

The (transformer + cap) thing is a 120VAC to 5VDC power supply. There are 2 of them, 1 to power the esp and one that comes on the relay board to power them. Two pins on the esp control the 2 relays which control the 2 outlets individually. (This is the equivalent of 2 - 15A smart switches that...

I wasn't aware of this wifi enabled Uno. It looks interesting and I'll be looking for more information, programming libraries and examples that are available. I suggest you do the same before purchasing and read reviews to see what you're getting into. Thanks for expanding my knowledge base.

I think you're right. Most smart switches that I considered were rated 10A with a few rated at 12A. That's why I built my own. Here's a photo of the one I'm using (on the left) next to another that I bought that had 30A relays, but a 10A terminal strip. The terminal strip on the one I'm...

Nope, esp8266-12e. I got a good deal on them, about $2.00/piece.

Overcomplicatotron might be able to help you. Here's his post: https://www.rollitup.org/t/offering-electrical-control-circuit-programming-help.987753/ Good luck with your project.

I have been looking forward to an update also... What are you looking for ttystikk if I may ask?

How computer savvy are you? Could you install the Arduino IDE (integrated development environment) per the instructions located here: https://www.arduino.cc/en/Guide/HomePage and get it running? That is probably the first prerequisite for anything I could show you. Even without an Arduino, one...

Have you ever wanted to build your own? There are many microcontrollers out there that, with a little bit of wiring and programming, will do exactly what you want to do. One that I'm familiar with, the Arduino Uno, has 14 digital input/output pins (for turning things on/off, (output), or taking...
