| Opening this thread so I and others can post various inexpensive (under $20) enclosures OR electronics devises that can be modded into vaping wonders!!
And I'm gonna start by posting a VERY interesting possibility that I found by accident! 
This lil devise has some serious potential!!

| Hey anybody..I want to take one of those digital meters and set it up for load testing...what type of cap should I use for that?...I figure a 47uf should be about right but not sure the type..???

The one I built only has 1 connector, not 2.
Ask Rocket to see if you even a need a cap??
I would think that you could just wire the two connectors together and attached to pin 1 and 2.
But I honestly don't know for sure myself. | |

| needs a cap to stabilize for reading pwm stuff..at least thats the idea...guess I just try the cheaper ones first

Let's find out for sure, huh?
So go and ask Rocket!  | |

| Cap would "stabilize" the reading somewhat but what would you be reading?
If a cap was all that was needed to read RMS voltage from a pulsed waveform the companies making expensive meters would go out of business

I didn't use a cap for the voltage reading.
But I also didn't add a secondary connector for an atty to test "under load".
Is a cap necessary for this?
Or can the 2 connectors be directly attached to pins 1 and 2 without a cap?

| Yea thats the same one..it cant read egos PWM it just keeps on fluttering
hopefully the cap stabilizes it enough...Im going to set it up on the bread board and see how it compares to the DMM with the cap installed

Might just be the battery fluctuating and the meter is not able to read the second decimal digit? | |

| well that meter is drawing power from the circuit.. as it jumps around the meter goes wonky under that condition..on the newer ones the readings jump all around the place when it does manage to actually get a reading

Input is usually required, out put cap not so much.

The meter I actually used is a much more precise and expensive DM!
Here it is: http://www.ebay.com/itm/280750720018
(Got a killer deal on it!)
This one measures 0 - 99V when connected to an outside source and 4.5 - 99V when connected to the mod.
It also has a micro potentiometer on the board itself for fine tuning.
I left it at its factory setting, but I'm sure that I could tune it to be more exact. | |

| So thats a 1 channel meter? I did use the cheap 1-6 channel one like mad vapes sells
It only goes down to 4.5V on the mod???

| My 1s-6s lipo checker, goes down to about 3 volts, maby 3.5 before it cuts out.. and that is fine for what i want.. | |

| thats confusing then...I mean those things are set up for RC batt packs and the like..if they cut off at even 3 V that doesn't seem to make much sense for monitoring the bottom end then....no wonder I haven't seen anybody using them to monitor individual cells in a stacked mod...sigh

When I completed building the mod enclosure with this meter, it'll measure down to 0V? while on the mod's power source.
I first used it on a single cell battery mod and it measured 4.2V off the charger, then after some vaping, 3.8, 3.5 and where I stopped 3.2V's (no fluctuation).
Does the other 7 pin meter do that on yours as well?
I wasn't expecting it to work that way considering the DM needs a 4.5V power source to function. Guess that not "actually" correct....or maybe I misunderstood? | |

| Ive had it run down to like 2.8 on stuff that Ive tried without PWM fine..well at least the one does..I think the bottom end is 2.5 according to the data I was able to dig up on it..
but Im not sure if they are all the same??..many look similar

| Well i below 2 volts leds cant light up, the diode breakdown voltage for conduction is about 2.2 volts... Minus losses in the meter it self, would give us some where above 2.5 cut off..
The meter dont have a power source to run the leds, so they cant read below the breakdown voltage..
BTW i made the mistake of buying some 2 s meters, and i was thinking, if i put one pin to ground, one to out put voltage, and one to imput voltage if it will work right???? | |
