$5.50 voltmeter with load checker.

[bigblue30]

I picked up this little voltmeter from the bay and decided to make a meter out of it. I can check the output of my mod with or without a load. It looks like this one:

I have to thank sassyblondeinwa for the case, and Dubs58 and atavanhalen for the motivation for this one.

I recycled the case from an old mod so it looks like crap inside…the next time I will use a new case. It still needs some buffing and a coat of clear on it.

Here is the circuit I used:

On

On the top is a switch that lets me check the loaded non-loaded output of the mod. With the switch in the N/O position it only reads the voltage of the mod without a load. With the switch pushed it reads the voltage with the carto in line.

This shows the mod connector end.

This is the Carto connector and switch end

.
This is reading the mod voltage without a load.

Here I connected a carto and pushed the button to read the loaded output voltage.

Here is the insides (I recycled an old mod for this just to see if it would work. Not my prettiest work…lol).

It is so much easier then using the big voltmeter. This thing also works as a great little pass through using my variable voltage wall adapter

might be cool to incorporate that into a varivolt mod, think it would fit into an AAx3 or 4 box, with a TI PTR08100W and 2 14500's?

I am looking to do one but I do not want it sticking out like this one:

I am going to try to replace the 3 digit readout with a 2 digit one...make it a little smaller.

Chuckling, Go figure - I was designing this in my mind this afternoon after finishing my 4th adj. voltage Tekkeon Mod (this one I think I'll keep). My plan is to incorporate an ohm meter in it to check atty resistance as I set my voltage..

MTW - Sweet looking Box!!

I know what you are saying SurvivorMcGyver.....I just posted on the other board saying that only 45 days ago no one was even talking about variable voltage mods......now we are seeing people talking about and building multiple adjustable mods, battery indicators, built-in volt meters, built-in ohm meters, thumb wheels, and more efficient regulators.

We are all talking and sharing our information with each other . I really do like this hobby and love the way we all are “pushing” each other to come up with better mods.

This is wild. I just received one I ordered from China yesterday. The same li-po meter.

I am planning on incorporating it directly into my mods, just for coolness factor if nothing else. It will show loaded voltage on mine. I'm thinking of just using it in place of the led. We'll see how it affects battery life but this device doesn't draw that much.

I must say, pretty innovative idea again Big Blue. BB, = Busy Boy.
you and SurvivorMcGyver Have me looking at my old multi meter to see if I can make enough room inside for bats, Regulator and a switch.

Keep up the good work and Push Push Push.

real nice bigblue.. I'd love to have one of those very convenient.

MisterD already did it:

So I thought I would try something different. I got 3 of the meters. One is in a mod already and one is this one....not sure what to do with the 3rd one.

Thanks RR but,.......All this mod stuff IS getting in the way of my beer drinking.....lol

The kegerator in the basement was empty for 4 days....Susie not happy.

Thanks Doots, It is a lot easier then pulling out the meter and the leads. I am looking for a smaller box for the next one. I think I can make it about 1/3 the size.

How about this one --

There' room inside for another read out and probably a circuit board for the Ohm meter.

Here it is at work

I got five for cheap at an online Auction -- Let me know if you want one BB -- this ones on me. (The raw unit that is)

Check out my Album at one of the links above

I went looking for a smaller box and found this 1.5 x 1.5 x 5/8 inch box in my junk box:

It still has the carto connector on top and the button to turn on the load.

Thanks, SurvivorMcGyver

The offer is for the box and not the meter...correct?

I just made a deal with the China guy for 10 voltmeters.

I'm curious... How are you guys cutting those square holes so perfectly for the meters?

That is the biggest pain in the ... about making this.

I use a Dremel with a cutoff wheel to cut the hole a little smaller then I need. The Dremel cuts and kind of melts the plastic as it goes, so the hole is very ruff at this point.

Dremel 545 Diamond Cutting Wheel 13/16" w/ Mandrel#

Then I use a small flat file to finish the hole.

Ditto on the PITA!! Did you notice the blade scratch on mine {opps} -- TWICE I slipped. I think predrilling and perhaps a fine tooth coping saw might be worth the effort here. Finish with a sharp exacto..

And yes, BB, no meter .... the toil and periferals are on you. I think I like your box better. Looks much simpler. But the offer is still open.... comes with a built-in 5 V regulator (500 mA charging circuit) 2 Li-Ion batteries and 4 cell phone adapters. PM me your address and I'll get one out to you to play with .

Just don't let Conman see this ..... He'll me all over it

I just need to find another box like that...It was a parallel d25 gender changer that I have had for years.
