REO GRAND Review by someone who has done his homework

[Rev. Stabard]

If y'all could think of anything else that you think would be beneficial, just post it. I will add text to the vid.

Here's what I have so far:

Hot spring collapses for safety

mod is designed to be cleaned by washing in the sink

Maybe that replacement parts are easy to get?

Oh, and thanks for your explanation. Having read what you said I wonder why people say the Reo has a higher voltage drop than other mechs. If the drop was mostly attributable to the coil resistance then all mech mods would have the same thing (disregarding the .1 drop from the mod itself, if in fact that's what it is.)

you sure bout that?

WHAT?! That's copyright infringement!You didn't ask my permission to copy me into a statue!

And you made my hair black!






yeah, in my dreams....

 

[oldbroad]

Russ! That was spectacular! You make an amazing video!

It definitely needs to be a stickie!!!!

 

[turbocad6]

awesome vid russ, you're a natural at it great review

 

[super_X_drifter]

Thanks so much for this review, super_x_drifter (Russ?)! This is very helpful to get me started in getting my new Reo setup! Much appreciated

Thank you.

Yes. I am Russ

Yeah, I'm not sure what the VD of the REO is but I'm guessing it's minimal. I think some others have tested it and it also includes internal resistance of the battery.

For me, what matters is total VD - like at the atty posts.

And yes, I do need to mention that replacement parts are readilly available and inexpensive.

Thank you

Killed it, Russ. As usual. Thanks for posting this!

OK, got the comments noted in the video. Thanks for the suggestions yall

Turbo, bro, Thanks, but I feel like such a tool in front of a camera. But for some strange reason I enjoy making these videos

You make great vids Russ thanks for sharing we all appreciate it . You do need a voltage meter I was cringing watching use that sternometer

Good stuff Mr. Russ! Killed me a little bit with the jumps on audio volume, but great vid! Now, we just need you to do a video on modding RBA's for BF!

I tend to stick to making vids where I know the subject matter. Trust me, you don't wanna see me brandishing any tools / defacing a perfectly good dripper

Yeah, when I switched over to the "other camera" (really just turned my iPhone around and pointed it at the table )the volume was high. Let me see if I can fix that.

Fleet, I am not the most scientific minded individual. That said, I believe that the voltage drop decreases as the coil resistance increases. I don't have the tools to check the VD of the mod itself but I'm guessing it must be less than .1v.

So in summary, if I was to wrap a lower resistance coil tne VD would increase.



Great point. I will add another speech bubble with that information . This video was my first use of text over the vid

Thank you.

Here's to hoping your mod doesn't have VD, that would be tragic

I apologize for not saying it sooner but I really enjoyed the review, it's almost like you know what your talking about

JK, it was great as usual.

Ha. Yeah, I had one but I hate the long leads. I want to (thanks for reminding me) upgrade the contacts in my Sternometer with some single strand copper like on my cartotometer.

Thanks Rob. Yes, making these videos entertains me quite a bit. I enjoy making them and your stuff is an easy target. Thanks for making IT

Nice job, Russ!! Always love your vids. Question for you on the voltage drop, if I may.... (And I preface this with I'm very ignorant when it comes to electrical circuits. I can use Ohm's law to calculate current, ohms and voltage given 2 of the three variables but I'm not sure how to apply it in this case.)

It looks like your measuring voltage across the pos and neg posts on the atty, with firing button down. How does the resistance of the coil come into play when measuring voltage drop?

Is it simply a case where current will take the path of least resistance therefore the coil doesn't matter at all? In other words, you could conduct the same test with no coil and come up with the same results? Of course, this assumes that the resistance, if any, of your measuring device is next to nothing. Or I have it all backwards and don't understand at all, which is entirely possible

I'm also assuming I could do the same test with a decent multi-meter.....

Thanks again!

The following are my initial thoughts, given my limited exposure to circuit analysis.

We can most likely model a REO as an entirely series connected device where the circuit model consists of a voltage source (the battery) and a set of series connected resistors (each resistor modeling one piece of the REO).

Voltage Sources:
VB - Battery Voltage

Resistors:
RB - Internal Battery Resistance
RW - Contact Switch Resistance
RA - Atomizer Body Resistance
RC - Coil Resistance
RM - Mod Body Resistance.
RP - Spring Resistance

Given each of these parameters, we could then calculate the voltage drop across the coil by using voltage division.

Series Equivalent Resistance:
RS = RB + RW + RA + RC + RM + RP

Voltage Drop Across Coil
VD = (RC / RS) * VB

This is to say that the voltage drop across the coil is proportional to the voltage drop across the entire device.

Updated to reflect the Spring Resistance.

as I've said before you can isolate the mod voltage drop and the batteries voltage drop by simply reading the voltage of the battery itself while firing, then read at the coil when firing, the difference between these 2 is the actual mods total voltage drop.

example, bat at 4.11v volts at rest, then while firing the battery drops to 3.95v at the battery, while at the coil it reads 3.85v... the total voltage drop of the mod is not the total of .26v, the battery is dropping .16v and the mod itself is dropping .1v only...

the truth is it doesn't matter all that much because a total drop of .26v is a good number to see AND if you do all of your measuring the same way including battery drop and mod drop then the readings are still relative to each other so in a sense this is nitpicking, then again... yeah

and Russ man, you may feel like a doofuss but it don't come across that way in the video man, I tried making a video myself of drilling a center pin for the divo and THAT was just painful to watch

I still wanna see your vid though. You gotta talk during it too

Thanks for the props bro. . You need to pop some pix of the fat boy up here too

 

[turbocad6]

no man, out of respect for Rob I won't ever show any of my own mods myself in the reo forum even if it's only a mod for personal use, I made that mistake before by not thinking, but I won't ever do that again

I will make another video showing how to drill an atty just never got around to doing another one

I didn't mean anything by my comments. Just trying to help clarify a previous question. To be honest, the resistances of everything but the coil are probably so low as to be ignored if not sub-ohming anyhow.

I thought you did an excellent job with the video Super!

Bro, you are such a redneck... Great review too... Kickin' some major REO AYuss...

Hey I appreciate the info you gave, and I was the one who posed the initial question. I don't think anyone took anything by them.

Thanks again, and Russ!
