Thread: volt meter

Any recommendations on inexpensive ones that have their own LCD? i.e. don't hookup to the computer?

a couple of ideas on this -

1 a basic meter w/ digital display - In the US, Target & Walmart both sell a digital display that has a cig-lighter plug on it, all it does is shov voltage of whatever you plug it into. it goes for about 15.00

Radioshack also sells these, in a kit or module form, for about the same price. I think they call it a digital voltage display module.... it would look nicer than the target one, especially if you were coing to custom case it. I can dig up a link to radioshack.com if someone wants it.

as for the pc side - I have been working on the basic stamp for about 6 months. I love these things, they have so manny possibilities. annyhow..... the volt meter module would work great, all you need is the module ( actually just an adc ) and the stamp, together they should cost about 50 - 70 bucks. depends on what stamp you get. the stamps are fun to play mith though, the larger one was like 7 1/0 lines anda serial interface ( plug into pc) and its pretty easy to write software to talk to the stamp, you could hook up all kinds of stuff between the stamp and pc, and use it to roll up windows, allarm, lock doors... tempature control. ok, Im rambeling. but that would work, and the software for the voltage meter is allready written, and freely availbel.

the last option would be - go to radioshack, or radioshack.com they sell a DVM that is pretty nice , that has an rs-232 interface on it, and comes with the software, it can read & report to the pc volts, amps, resistance ...etc. I have one, I can look at the model number if annyone wants to know. it cost me about 60 - 70 USD I think.

I know my Asus motherboard can tell you all that. It tells you all the precise voltages, fan speed, and temp in the software.
