Ive been thinking of getting a voltmeter for my Blast City Cabinet, as this would negate the need to use a multimeter to measure on jamma edge.

I see a few on sale on ebay, but anyone know any recommendations?
 
They’re fairly simple devices, not much to them. Just get one that’s built solid. I have a few JAMMA pass through voltmeters that Frank made when he was active, but I believe @FrancoB or possibly JNX have solutions too?

I still use my multimeter to test in a cab, even though they all have voltmeters. The voltmeter range sometimes gets funky when there’s a big fluctuation, even after adjusting it perfectly.

the aliexpress etc ones are fine, you can even get a bench power supply and adjust the potentiometer on the voltmeter so it reads accurately (if its a little bit out).
they come in tons of colours too. i just use Wurth double sided tape to adhere them to things, if no other fastening option is available, or if 2 part glue is overkill.
 
I use JNX products (@XianXi) also, they work great. Just remember if you get any voltmeter, they need calibration. There’s a little potentiometer on the back side you turn to adjust the readout. I set my power to get 5.00v reading on a chip with a multimeter and then calibrate the pot so the readout shows 5.00.
 
I use the JNX Atlas. Has the voltmeter and is very well built. Have been using it for years. Also has a kick harness connector that comes in handy for mobos like the Atomiswave that require 5 buttons. It maps the extra 2 buttons to 6 button controllers.
