Hi Matt,
I think it's great when people get interested in electronics. I myself
have learned a LOT since I started reading the PIClist, EVlist, and
EVtech lists [EV= electric vehicle]

You could build a boost converter just to see if you could make one
work. I would highly recommend you experiment with 5 or 12 volts before
you mess with 170 volts.

You could try making an unregulated boost converter with a PWM signal
from a PIC or a 555 oscillator. Keep your duty cycle [on time] low so
you don't break anything until you learn exactly what's going on.
I think it would be easiest for you to start with something simple like
this then move up.
Glad I could help a little
