Re: p.p.m to p.w.m conversion
thank you joesmith. that is an great website.I've still been lookin around and came up with some info in seattlerobotics.org on servo modification.The neat part is the hardware design gives me good insight about possable programs for the stamp.Now to get down to basics whew!!

Re: p.p.m to p.w.m conversion
Thanks for that info,James.I just finished researching that before i posted this question.There were many sites listed but none seemed to be responding.I did find one analog version but no leads reguarding the use of pics.It seems like any information related to that subject has been erased.

Re: parabolic microphone
try the"reader's guide to periodical literature" it might be on line by now.You may have to use the local library to search back about 15 or so years.
I think there was one in popular electronics and a couple of the science and or mechanics zines. Ithink one was called the big ear.

Re: p.p.m to p.w.m conversion
basically,the h bridge gets switched by a signal that changes when the pulse is positioned past the the center of the of the timing cycle.This signal can be used to switch e relay.I think the best way to do this is to create a counter that counts how long it takes for the pulse to happen and convert...

p.p.m to p.w.m conversion
hi, T'm looking for a way to convert the servo output of an r.c. reciever to p.w.m to control the foward and reverse speed of a motor.Instead of using an h bridge i want to use a relay to reverse the motor. The speed must be ramped up with an adjustable rate.I think a pic would handle this but am la...

Re: Question about a Headlight modulator schematic
it seems to me that if the oscilator is working you need to get the headlamp connected between the drain of the mosfet ant the positave sopply for the headlamp.
