Need help ohm meter build.

Ok so I am wanting to build a nice ohm meter but I'm not sure how to go about doing it. So let me state the reason for the build and purpose of it.

I use a ohm meter for vaping to test my builds so that's the primary purpose, I have already got one I bought for this reason but I like to tinker around and well try and make and find things to make it better so I want a new build. If possible I would like to have this thing read ohms, volts, and amps of my builds. Is this even possible? Is it possible to have a display like the one in the image I included? Here is the current ohm meter I have at the moment with the specs of it **broken link removed** .has a 510 connector which is what I would like to use..... So any input would be appreciated on this build or if it's even possible..and would like to be able to have it all enclosed in a nice box as well even a project box would probably work . And just to add I am a noob with all of this type of build

Well, I'm not saying that it couldn't be done, but the results of your work will be shadowed and even surpassed by any cheap multimeter.

Now, I don't want to kill your DIY flame. What about measuring other interesting value, like temperature, very small resistance, Capacitance, Inductance, ESR, maybe Frequency?

Or try a current clamp meter! it would be a better addition for your toolbox.

Well the ohm/volt meter I have now works for just that purpose shows me the right ohms I'm at as well as the voltage of the mods. But I didn't know if there was a way to build one pretty much just like it but with a bigger display with more decimal points to get more accurate readings on ohms. Just thought would be neat to build the ultimate ohm/volt meter lol and. It sure on how I could build one to measure the other things you listed

It's certainly possible to build one but the cost would be much greater than buying one ready made, not to mention the design and build time it would take. It's far from a trivial task to build one more accurate than the one you already have.

If you buy a clamp meter beware the majority of them esp cheaper ones will only measure ac.

This is certainly a worth while project as a learning experience. I too was interested in building my own test equipment when I first started, and you can learn a lot about non ideal components and error sources, something most amateurs know nothing about. However, unless you are a lot better at building than I am, you not create something more useful than what you can buy.
