Re: how antenna radiates
I have been studying this also and this is what I have discovered:
In our universe, there are phenomena that occur that we are trying to understand completely. Sometimes even though we don't completely understand we can do useful things with what we have observed. In...
Re: Ejection charge circuit question: Circuit clarifications & High Side Switch Quest
Thank you for all the input, here is the corrected circuit.
Does any one have a suggestion for a high side MOSFET that can be controlled by a logic level and handle 5A?
I picked the IPS521G as an example...
R1 Should have been 15k Ohm, and I also forgot a divider stepping down the 9V into the a/d pin.
I like the high side smart switch idea, it gives me one more way to keep the squib disarmed until the uC is ready to start the timing cycle.
Any ideas on a suitable part number? Depending on the...
You are correct, I neglected to add the divider circuit there.
You are also correct in that a NE555 would be simpler as a single timer circuit but not that easy to adjust in the 0.5 - 240.0 second range I require.
Sometimes I need 65.0 seconds, sometimes I need 75.8 seconds from launch to get...
Just a thought, but in prosthesis design microcontroller driven memory wire could be used to smooth out tremors in fine motor control.
The "art" is in the control software itself, use MATLAB to model the system and tune the PID parameters.
Search for terms like "Robust System Design", and...
I am designing my own version of a timer designed to eject the parachute of a high powered rocket at a preset time after liftoff.
Using the circuit below as an example, I would like to determine ahead of time if I have continuity with the squib (a nichrome wire dipped in Pyrogen electric...
