hi alll
sorry out of topic a bit
i also DIY one voltmeter for myself

but it is actually not digital.
it is analog.
its quite cheap. i buy this panel meter for RM16
than i add in LED inside
(LED i got free... take from old computer casing)
add in some cable.. and walla... i got one voltmeter..
total 3 wire comes out... +ve for light, +ve for volt reading, and ground

i know a bit ugly la...
many fren say is ugly
but i happy la.. i can view my volt...
and the meter can be calibrate also.. next time when it not accurate, can open up and turn the screw inside.

nice job sam.. it serve the purpose to monitor volt... hell yeah... but that kind of meter got smaller scale or not?? like 0-15v??

 

[tk2005takeru]

Sneak into the school laboratory and steal the voltmeter inside. :shades_smile:

 

[sam1741]

yeah.. the purpose is monitor volt.. and i happy with it. :)

got.. i sure there are smaller scale
but the shop i go .. out of stock, so i take this 0-30v one.

in fact if you know the calculation, you can buy one am-meter and turn it into voltmeter with any scale u like. :)

 

[donCityZ]

ONLY V=IR right?
