fuel gauge idea
:cool: what about the other type of float switch on the Maplins website
perhaps three arranged vertically
to three leds /lamps
low /half full /full
what do think good /bad/crap/or bloody stupid ???????
les g: :eek:
A little coarse, the last one could be set so you have say 1 gal left in the tank when it comes on. Also there would be no damping so as you go around corners it would be disco lights
ok yep i can see that
what about some baffling in the tank
or could they be wired in someway that they only trip the light if the float is continually activated for a specific time ie some kind of smoothing
or could thy to say five lights so at some position two floats are operating intermediate lights
any thoughts any clever electrical boffins??????
or just forget as too!!!! much hassleand junk the idea""""""""
The output from the sender follows a specific range of resistance and with a little clever electronics is all you need to trigger the LED's.
Standard senders run 33 Ohms full tank to 240 empty.
You could have all LED's on when full and loose one every time the fuel level drops past a certain point.
With 5 LED's you could have 3 green 1 yellow and one red.
It wouldn't be to hard to do a DIY circuit that waits for say 4-5 secs before accepting that the fuel level really is that low, not just cornering. Would almost cirtainly need the use of a PIC (proggramable intergrated chip) and a little know how though. Try searching for 'PICAXE', I've used many of these chips and they have a great 'teach your self' section.
That's the sound of anything electronic going over my head!
wot we need now is one of these boys to post something that says you do it like this tah dah !!! its easy (or i can make you one for a fiver ) even better
eh chris lol
