Make your own OHM meter for FREE. (well almost)

[Sizzorfite]

Here's how I made my FREE ohm meter.

I used an ohm meter I got from Harbor Freight with a coupon for Free (including battery).

First, I pulled the connector off of an old ego battery I had laying around and removed the guts from the inside.
Remove the center pin from the rubber grommet, Then solder a new wire to the center pin. Thread the new wire through the
grommet and push the pin back in.
Next, solder (or twist) another wire to the outside shell.

Now drill a 12mm hole in the top side of the case. Slide the connector in and epoxy it into place(first pic).
(even better if you have a thin nut to fit the ego threading)

After everything is set, connect the wires as shown in the pics and put the case back together.
The center pin wire is the Positive +. Connect that to the fuse.
The other is the ground. Connect that to the grounding bar.

Now THAT'S how ya do it!!!! awesome!

You can even get 510 connectors from madvapes too

I so want to do what with my multimeter...

P.S. they are only $3.99 anyway

Also with these adapters you can check the output voltage of your 510 devices

Would you recommend using JB weld or some other two part epoxy to hold in your ego head?

Thanks,
I think any 2 part epoxy should work fine.
I used 15 minute epoxy I got from home depot on mine and it works great.

with my multimeter (the exact same as yours) I need to substract about .8 ohms to get a good reading, do you have to do the same with this moddification

I just used heavier gauge wires (24g I think) and made them as short as possible.

why not just use the multimeter?

I tried that but the reading was way off. A 1.8ohm coil would read as 2.8 to 3.0 ohm.
Plus, it's much easier to just screw the coil on the connecter instead of fooling around with the probes.

 

[hazarada]

you should have invested in some alligator clips for your multimeter. The reading is off probably because the tips of your probes are dirty, you can try it by pressing them on the metal harder. Wouldnt have that problem with alligator clips though which are also faster than screwing it in there.

Now its a multi-multimeter

Normal people... believe that if it ain't broke, don't fix it. Engineers believe that if it ain't broke, it doesn't have enough features yet.

I do like the idea but I want to build the 510 on top that way I also have a base for working on the wires and don't have to use the mod

Oh man, this made me giggle.

I love this idea, time to break out the soldering iron.

thats a fashion accessory not a feature

Why would someone make a VV Mod out of a Ultrafire Flashlight when they could just use an eGo?

For the Cool Factor.

It's all about the Cool Factor. And Sizzorfite's Multi-Multi-Meter rates High on the Cool Factor Scale.

The probes are brand new. The wires on them are just too long for a proper low ohm reading.

 

[hazarada]

must be some really horrible wires then, mine are around a meter in length and give the exact reading

Sizz.....I ran across your thread this afternoon, while I was looking for something else, good job bye the way.

This got me to thinking.....Great minds think alike (not me), the Rocketman.....Here's his thread from 2011
http://www.e-cigarette-forum.com/forum/modding-forum/213180-rockets-carto-meter.html Sad to say, all the pictures have gone to that great recycle bin in the sky.....But as luck would have it, I did save some of them, for my"Things I might do later" file.

The picture in the bottom right, we will get to later.......You will note that the board in the older HF MM is some what different than todays MM......Also that it is wired to read voltage too.....Here is where I hope you don't minded me high-jacking your thread a little bit....

This is where we get to picture in the bottom right, first picture.....That is a tester I made a year are so ago......I think with a old half of a carto wired like I did in to your picture, you could read ohm's, voltage, and voltage under load....

I do hope you don't mined me doing this........

duckie.......

That's pretty cool...

Now this is one heck of an easy mod! I just might have to try this out myself with one of my extra meters (I think I have about 3).

In the meantime, I actually purchased a DIY Ohm meter kit from MadVapes that I plan on putting together inside an old Carto Tank. I figure my Magneto is already a battery and a switch and a connector, all I need is the Ohm module. and another connector and I'll have an even smaller Ohm meter than the little black boxes.

 

[GreatGoazoiu]

how well would it read sub ohms if i did this? would it be easier to just buy an ohm meter for 25?
