led fuel fuel gauge

[les g]

hi to all hope everybody is well
a while ago i posted my thoughts on using switching to run a string of lights/leds for a novel fuel gauge the opinion was its good but might be coarse in method and needed to electronic rather switched (at this point no electronic boffins stepped up to the plate and offered to provide a solution )lol.
so done some research and a guy who has already done it:
www.mez.co.uk/ms13.html
its also been copied and photo documented on
www.mevrocket.talktalk.net/petrol%20tank.htm
now all we need is someone to turn those into a linky
hope this is of interest
cheers les g
