InTheShed Grows Inside & Out: Jump In Any Time

Anything can be confusing until someone explains it to you in a way you can understand. That's what Sam did.


So just put the probes in the outlet and read the volts with no draw on it?


I figured it was some engineering or universal symbols, but for the rest of us, common abbreviations make it so we don't have to sift through the explanations to figure out what we're talking about.

W=V*A is obvious since we're discussing watts, volts, and amps. That's what the meter says as well. P=V*U first needs to be translated into common usage to be understood, which is what you did by writing out the explanation.



And just to make sure...if my voltage is 115, then I want to dial the amps down on the pot until the meter reads 2.17 to get to 250 watts, yes?

250 = 115*2.17

Correct.

I hear what you are saying but to simplify equations certain symbols are used to standardize the variables so other engineers and science professionals know what is being calculated. I know it can be confusing. Just be glad you are not working with gears.

I am! I'm happy when nothing's grinding them too .

I can work with rear end gears in a car i can figure out what the ratio is on a ring and pinion set and give you your output ratio thats not hard at all..

 

[SamSmith]

I deal with that crap daily. Mechanical design is what I do. It's fun but there is a lot more that goes into things than most people know. I hold multiple patents on pumps that turn liquid soap into foam. People use them everyday and don't understand what makes them work. It pays the bills though

I like that ..say that again my brotha...

Ratio's aren't but the design of the actual ring and pinion are what those formulas are for. Things like lash, pressure angle, and geometry of the teeth are.

Lets just hope Shed doesn't knock out the power on his block when he is doing this or end up with curly hair and charred hands.

Yup lash is definitely important or youll get that roaring noise... in which u better get em fix quick or youll be back to that design where you have a frame with 2 pedals and a chain you get the rest...

Thats what i was saying.. will get a pic of the guy from back to the future but in real reality form lmao..
shed just when u hook it up rrrrrrruuuuunnnnn...............

Nice one Sam! I actually do wonder about that every time I use one.

I'm okay at wiring stuff. You just follow the flow of electrons from point A to point B. As long as the connections are tight I'm not concerned about that. And my hair is already curly but I keep it short for that reason .

Tell my why my gear shift sometimes hits the bar of the H going from second to third...in a PM please!

Shenanigans! I guess I should have known that's what I'd find here lol!

LOL! We're always up to something here AW .

Wife had the day off, we did breakfast and a movie . Itching to look in on the plants but its lights off.

Noice! Hope it's not raining there .

Anyone used Floramax Root-XS? It doesn't get mentioned on the boards here.

A liquid plant fertilizer containing:
Potassium nitrate 3%
Potassium hydroxide <1%
Listed at: 0.3 - 0 - 1
For roots and foliar spray.

I now have 1.3 gallons of this to go along with the 7.5 gallons of Terpinator (which I'm thinking of drinking at night with my vitamins).

Oh, and I forgot to drop this pic on y'all today! Candidas on the mat on day 7

I'm not interested in the efficiency of the driver as I already own it!

If you want to calculate you AC draw, then you are interested

It's 94% btw


2 ways to calculate your AC draw from specs:

Using the first: 299V * 1,05A * 1,06 = 332,787 Watt AC

Bamn.... here comes more math. We finally got him settled down enough to post some weed pics... LOL

Don't worry about it Sam. I have no idea what PGR is talking about .

I'm not calculating anything from the specs. I don't care about the efficiency of the driver or the boards (I already own them). I just want to know what the actual wall draw is as I turn down/up the pot on the driver. It could be a vacuum cleaner for all it matters after that. The lights will kick out whatever they kick out at 250 wall watts.

Yes i agree lets get photolithickly high ..

Uhhhh nomore math my brain is melting...
ima be doing algebra in my sleep now lmao..

 

[BigBearNTexas]

Who knew I should have taken Physics in college to be able to grow plants?! Lol

 

[PurpleGunRack]

You don't have to know Just put your numbers in the formulae.

I'm not talking about the lm/w and stuff like that, it's how big a cut of the power the driver takes to convert the AC power from the outlet to DC power going from the driver to the strips.
Some of the energy is wasted as heat (6%) in the conversion, which is why you need to add that if you calculate from specs.

250 / 333 = 0,75 = turn the pot. around a quater of the way down and you're around 250w draw from the outlet

Easiest/safest way is to just get a cheap watt-meter and dim the driver to 250w
