MPGuino show 'n' tell at Ottawa EV meeting
I brought the guino to Ottawa last night and gave a brief presentation at the "round table" session. It was well received and more than a few members said they'd be looking into it after the meeting.
Why would I bring a guino to an EV club?
1) Most of the members are tinkerers by nature and I thought would find the project inherently interesting;
2) Many of the members who also own ICE vehicles are conscious of managing their fossil fuel consumption, so would be interested in a ScanGauge or MPGuino;
3) Since the Guino code & hardware is open source, I suggested the project has the potential to be modified into an open source energy monitor for EVs, showing Watt-hours per mile instead of MPG. I think several of the Ottawa members are capable of tackling that kind of thing.
The VSS could be used as-is in most conversions, and instead of monitoring a fuel injector, it would be a matter of adding a voltmeter function (to monitor pack voltage) and milivoltmeter function to measure voltage drop across a calibrated shunt to calculate current (most EV conversions have at least one shunt for an analog ammeter gauge).
I should probably mention it on the EVDL as well...
