Has anyone included a battery level indicator in their builds? Any ideas how it could be done?

I used one of these and put some neutral density film over it to dim it down: http://www.ebay.com/itm/Two-Wire-0-28in ... 1c4611798d

Yes it dose lenny :thumbup:
In fact it was your brilliant build that put me on this.
Many new members haven't had a chance to see it. It was brilliant.

Let's have a look at it again, please.

Be interested to see the wiring for the osd, the PIC seems to show two battery inputs

I have these in my new builds that i am developing at the moment, torchwood is right, they are good......but on some testing they do disappear in some light situations.

This is one of my test rigs with the voltage meter plugged in, sorry its a little messy but they are easy to wire up!
