Designing a parachute system/device

AI Thread Summary
A user is developing a parachute activation system that triggers a servo when a signal is lost between a machine and its remote. They are considering using a sensor to monitor the two-way signal, which would activate an actuator upon signal loss. Questions arise about whether to integrate a transmitter on the plane and connect it to a circuit for automatic activation. Concerns are raised regarding the airworthiness of DIY parachute triggers. The discussion emphasizes the technical challenges of linking these components effectively.

I am trying to build a system to activate a servo at a unspecified point in time when a machine and remote looses their signal between another. When the signal is lost between the two, the new system must activate a servo. We are using radio transmitters, but I can't figure out how to tackle this problem. Any assistance would be LOVED!

The biggest problem I am having is how to link these three things together. I was thinking about using a sensor that monitors the 2-way signal between machine and remote with a LED, then the LED turns on or maybe stops the LED when the signal is lost, then activates the actuator... i don't know...

can i build a sensor that does this?

Should I buy transmiter and put it on the plane and connect the reciever to a circuit that activates the servo? I am trying to make this happen without me doing it manually. Does this make any sense?

You could have a spring loaded device that is prevented from tripping as long as the signal is present.

More important, I can't imagine any DIY parachute trigger meeting anyone's airworthiness criteria.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
