Need help finding some place to snag a few 0v - 5v digital display meters ( Found a place : )

This is related to overclocking/modding as these 5v meters will be used to make voltage panels for a few overclocking projects I'ma be undertaking. I need about 9 5v meter that read 0 - 5v and have Red or Blue LED displays.

I assume at least one hardcore overclocker here knows exactly what I'm after and where I can get them.

I'm looking for an online warehouse or E-tailer that sells these things and the best people I can think of to ask about them are hardcore overclockers.If anyone can help me soon it'd be greatly appreciated as I wanna make some live voltage adjustment panels that display the voltages as you change them so there's no need to go into the bios to stabilize an OverClock 🙂 Gonna be making a few of these panels and modifying some mobo's and video cards so I can set bios settings that let me into windows then sit there and tweak voltages till my desired OC passes OCCT/3DMark without issues 😀

maybe?

I have nfc what those are. The diagrams look like potentomters but the descrips say current sensor 😵

Abit used to market a Guru Clock for just this purpose. If you find where to buy one, let me know.

For starters I don't just need a simple LCD display, I need a 5v Volt meter with a Digital readout. Think more single task multimeter than basic LCD display.

The uGuru clock won't fit my needs as I'm going to be making the front panel readout and want to put the potentometer dials and LCD readouts on the same 5" bay drive panel I'm going to make. Plus buying a pre-made stup kinda defeats the purpose of modding to start with 🙂

If I can't find anything them I'll just buy 9 backlit Multimeters from the local " Harbor Freight tools" and crack them open and mod them to fit my needs 🙂

I kinda figured it wasn't gonna fit your needs, but I need at least one screw-up a day to make sure I'm still breathing! :laugh:

Seems you can buy them direct

I tried that @ 6 months ago....they're still not in stock. By the time they get 'um, my buddy will probably have another board! :laugh:

Not backlit LCD or LED. Want the numbers to be easily viewed without having a light shine on the tower and from a lil distance, this is why I'm after a backlit LCD display or an LED display. I can get backlit LCD multimeters from Harbor Freight tools for about $6 each atm but I'd have to modify them to fit my needs and I'd have to make a setup to reduce the 12v line from the PSU to 9v to properly power it without frying it.


I might just buy 9 of these multimeters and modify them if I can't find actual 5v voltage meters with Red or Blue LED displays 🙁

3-1/2 digit LED digital panel meter with black plastic bezel and face plate - BGMICRO

5V operation, 200V/20V Range Red LED

If it'll opperate on as little as 1.6v then it'll be perfect 🙂 Prob gonna buy one to test with first. Seeing as it uses the voltage being measured to power itself it might not work for all the voltages I gotta monitor.

There is something wrong with that description. It clearly states that it operates on 5V/135mA. That is a separate power line feed, not the signal line. Note that the input impedance (signal line) is 1M Ohm which means that it would only take 5 microAmps for a 5V input, which is good, but in no way would it feed itself from the signal, which if you think about it, you don't really want.

As for measuring 1.6 Volts, yes, it should in the 20V range, and one could assume with with hundreds of a volt (10 mV resolution), but there are no statement about accuracy.

Oh, I intended to use both of my multimeters to test the voltage the LCD meter would be reading anyways. That way I can mark on the panel the offset. If it's accurate then great, if it's negative .01v off then I'd mark that on the panel below the LCD 🙂 I know better than to put blind faith into a single reading.
