Aim
I plan to make a multimeter(a cheaper alternative to fluke multimeter or so) with logging capabilities and to produce graphical data about the variation in the input value.

Nomenclature
Raspchap multimeter = Raspberry Pi 2 Cheap Multimeter

Features
-->Measure up to 100 V ac and dc

Code:

(by using a voltage splitter to reduce 100v to 5 v)

:-->Resistance

Code:

(by using R=V/I)(0.1 Ω to 5 MΩ)

:-->continuity testing

Code:

(two separate GPI pins)

:-->NPN or PNP testing

Code:

(using 8 gpio pins)

:-->diode testing
:-->Min/Max and average recording to capture variations automatically
:--> Channel input for testing

Code:

(therby using 8 GPIO pins)

:-->Temperature

Code:

(by using a thermistor) (2 separate gpio pins)

:-->Logging the variation in input in graphical way
:-->with 4' display to display the readings

Code:

(separate gpio pins)

:-->3 years warranty
:-->Gaming while recording data from input

Code:

(using our beloved xbian os)

:-->Uploading the data to a server (to access it from any where around the world)
So you got a PC with all the capability of a mulimeter..
