New Foot Pedal

Tuesday, July 10th, 2012

Well, the old potbox was severely misbehaving, so I replaced it with a Curtis FP-6.  Very solid, very nice.  Well, it’s kinda big.  But solid.

So, I pulled out the old gas pedal, and tried placing it on the floor.  It sorta worked, but quite awkward to use.  So I took out the old floorboard behind the gas pedal, made a new one I could mount the pedal to, and it is now quite usable.  Especially when the carpet covers the wire and box.

Here’s what it looks like:

Gas Gauge Working

It took a while, but I now have an embedded computer listening to the current going in and out of the battery. It is able to calculate the state of charge (SOC) of the pack, and display that value on a LCD screen.  Simple enough, right?  Just took time and shaking rust off some very old skills (wire-wrapping and soldering).  In order to save the life of the auxillary battery, I have two power sources going into the computer.  The battery directly powers the computer, and the keyed +12v drives the display.  I’ll get some photos up later.
