Master Series Voltmeter
Posted 25 April 2008 - 07:13 PM
A while back, I believe Dan Coplan posted a picture of a little voltmeter he'd picked up and turned into a battery meter. I liked the simplicity, size, and price of the thing ($30) so I picked up the same and proceeded to disassemble my rig.
In a moment of what can only be described as serendipity, it turns out that beneath the plastic shell of my battery base, there are slots cut into the metal framework. One of those slots happens to be almost exactly the right size in which to fit this meter. So I tapped into the wiring coming from the secondary battery, slid the meter into the slot and project done!

If you want to cut and file or sand a hole in the old cover piece and re-attach, it can be done, but the dust from that stuff is nasty; wear a mask and vacuum constantly. Also the fibers (if they separate) are like nasty little knives.
I've gaffer taped both sides around the hole to be cut, gone slowly and made a big mess along the way, but it works.
BTW, I may have a spare one of those covers in a drawer somewhere, in case you want to go back.

Just out of interest, where did you pick the voltmeter up from? I hardwired the Astro Flight Meter into my sled- does the job, but not always easy to see, and has more info/smaller digits. I find it harder to see especially when it's a darker environment, largely down to a poor viewing angle and smaller characters.

I tracked these down, for any interested UK folk looking for voltmeters for any of your rigs, Farnell sell the range of these Murata power meters.
