What is the FuelBot?
The FuelBot is a combined Fuel Gauge and MPG Meter. It measures fuel consumption by monitoring the SV's fuel injector signal. Info from the SV's speed sensor (distance) allows MPG and instantaneous MPG to be calculated too. So far, the FuelBot has been tested on my SV650, and also on RecoilRob's SV1000 and SteveSLO's SV650, and works, well, fantastic!
How it works:
The FuelBot takes control of the SV's tachometer needle to display Fuel level, MPG, Gallons_left, and Gallons_used. Precision is one thousandth of a gallon (1/8th oz); accuracy is 2% or better (with calibration). As shown in the video below, a mode select button switches the tach between RPM mode, Fuel level mode, MPG mode, etc... Distance Till Empty (DTE) is available on the LCD.
FuelBot Unit
FuelBot Harness
The LCD below is not required for FuelBot operation. It was intended for development use only, but is handy to have, so I figured I would offer it as is. As shown, it is NOT weatherproof and requires some sort of user supplied enclosure. If you come up with a good enclosure solution, please post it!
A bare FuelBot micro-controller chip will be available for $25 shipped, including schematic, parts list and layout. All other parts are available locally or on-line. Parts and assembly were purposely kept low tech (old style thru hole assy, with an off-the-shelf RadioShack protoboard) so folks could build their own unit.
If there is demand, I will assemble some units, maybe $110 shipped for the FuelBot with harness?; optional LCD $35?; does that sound reasonable? Parts are cheap, but it takes a few hours to assemble and test. Mods, please let me know if any forum sales rules apply.
I am working on a custom enclosure for the LCD (the LCD by itself is not weatherproof) but don't have anything to show yet. RecoilRob came up with a nice enclosure solution, and I'm sure the creative folks here at SVR will have some good ideas too. :naughty:
Big, big thanks to RecoilRob and SteveSLO for helping me test the prototypes and work the bugs out; your feedback and suggestions were invaluable! :rock:
Any interest in this?
Thanks!
