Today was a big day for the electric lemon. I tested the motor and
transmission in the car for the first time. I used a single EV-95 NiMH
module to power the motor. Power was controlled using the arcy-sparky
method of touching two pieces of metal together. The wheels spun quite
happily in first gear as can be seen in this video.

I tried all other gears as well and things seemed fine. The gearbox
is still far louder than I'd like but this is under no load. Hopefully
it will be quieter once I get certain things like the hood,
upholstering etc into the car.
Having come this far I couldn't resist the temptation of taking the
lemon for a totally uncontrolled test drive. I hooked up some longer
cables so that I could control the power from the driver's seat. On a
single, mostly discharged, battery module I was expecting it to just
lethargically inch forward at a leisurely pace. The result was quite
surprising.

The car lurched forward nearly knocking me into the back seat. The
acceleration was brief but sudden and the top speed wasn't exactly
spectacular but it was far more than I had anticipated.
I spent the next half hour driving the car back and forth with a mad
grin on my face. I wonder what my neighbors might think...
The good news is that second and third gears are far quieter than
first. The motor was even able to get the car moving in fourth gear
without too much effort, I never tried fifth. More importantly I now
know that the transmission actually stays in gear under load;
something I was a bit worried about.
