Yes, i probably should, i have looked into a couple open source
packages a little but haven't had time to really try them out. I think
what i am going to do for now is scrap the h bridge for now and use a
servo to toggle a switch, if we win and go on to the state competition
maybe i will be able to build one, but hopefully the servo will work
for now. (p channel mosfets aren't available locally at a reasonable
price and we don't have time for a digikey order).  i am going to
pulse with one mosfet on the low side of the circuit so i shouldn't
run into problems. now all i need to do is build it and finish the
software.

thanks again for all the help
