    Fuel gauge

    in General paramotor discussion

    Posted

    Im sure this guy is on the forum

    He mentions a fuel low level light in this video and how he did it.

    Just had a look and he uses the same switch as I have gone for, but may be cheaper as from a different manufacturer. He only has the one sensor so the two LEDs are overkill really.

    There are two manufacturers, Gem and Honeywell...

    The deisgn id so very simple, nothing to go wrong really.

    You're right Gordon, I guess we should always know how much fuel is in the can. But, like on a car, it would be nice to have a little reminder maybe? For the times you're having such a good flight, times literally flying...and before you know it, the motor is coughing and spluttering...

    Mentioned the multiple sensor idea before but at £13 a time without the LEDs we are getting near the price of the micro fuel gauge already made up!

    Oh ok, well I worked it out a bit cheaper...

    Miniature case: £1.59

    Green LED (8mm): 39p

    Orange LED (8mm): 39p

    Red flashing LED (8mm): £1.09

    3 Level Sensors: £40.98

    Sundries (washers etc): £3.00

    TOTAL: £47.44

    Plus, assuming it works, it can be bought it kit form and made yourself...or pay a bit extra for the PMC, prebuilt version. You also have the choice of going for a simpler version with only the one sensor and flashing red LED for when you are low...

    I looked at Jim Weirs site just now, that 'PCB' looks a right mess!

    This kit is for 'fluid' so will need to take into account the properties of petrol. I like the LED arrangement; http://www.electronic-circuits-diagrams ... ckt6.shtml

    Some more info here, schematics etc...; http://www.rcgroups.com/forums/showthread.php?t=914185

    Can we not have this sensor at whatever litre we decide is 'turn around now', then simply run it to a small 'hobbie' box mounted on the chassis with an LED and 9v battery inside? Or, another two or three if you want 'full' tank, 'half' and 'low'... http://docs-europe.electrocomponents.co ... 40c2e2.pdf a single sensor is only £13...

    Capacitance is the way to go. I have a schematic around somewhere for a similar monitor I made for my nitro car a few years back. Essentially the same thing but on a smaller scale.

    I'll post back when i'm home and on my PC. You can also buy specific RC fuel level gauges...

    I finally got into the air...

    Sorry pete, didn't see you post in there.

    I wasn't directly into wind to start, then mind went blank. Something freaked me out for some reason, but don't know what (fear, trepidation, who knows. My ex says it's because i've always been afraid of commitment). I kept thinking I was going to get pulled back and hit the cars...and trees...and fence...which actually then caused me to do just that. Self fulfilling prophecy I guess. I literally just froze. I know what to do in that situation but just didn't do it. It didn't help that I didn't commit fully on the power, I staggered it initially which started the ball rolling (well, it was me rolling actually).

    I was under instruction, with Simon. He was on the radio telling me what to do, but my hands just weren't doing it! Then it all happened a bit too quick with the crosswind, what with the trees and barbed wire. I guess it was the impact that bent the frame, which then hit the props during the 180 over the fence.

    So, nobody to blame but myself. Just gotta get back on that horse...when I get the bill for the repairs to Simons motor...

    I finally got into the air...

    ...about 60ft in wrong direction, through the barbed wire fence and into the other field!

    One bent titanium frame, three carbon props destroyed, all clothes wripped. One extremely damaged ego!

    So, sorry to everyone, especially Alistair who's day I ruined...and Simon for the minor scuffs on the parajet!

    I'm off to get the rope and find a nice high beam!!!!

    On the plus side, Dave finally got into the air so congrats (any chance I can borrow your motor for some practice...)!
