Spark gap transmitters are the oldest type of radio transmitter made by man. They were first used around 1888 and remained legal until the 1920s when their use became greatly restricted. World War II delayed their complete ban outside of emergency communications for a few years. Now the only way to use them legally is inside a faraday cage. They operate as jammers for the same reason they were banned, they take up a lot of the radio spectrum.

Also in other news the gubberment tries to push more rules and regulations on drones due to interest and lobbying by large shipping companies especially Amazon. It is getting increasingly hard to fly a drone even though such regulations and laws are never upheld (do you think the police will go around with a drone scanner?)

im not watching an entire 34 minute video "about drones" just because you posted it please link to specific parts of the vid or at least summarize it to summon interest

sorry about that,
basically you are now required to present a remote id that is being broadcast at all times, your transmitter must also be connected to the internet at all times. while this is fine for a commercial drone use as a DJI phantom, it is not for the case of a hobbyist made drone as the one depicted on this topic. Because regulation had a very vague statement about Hobby made drones and how it can broadcast the ID or not. to comply with the FAA's new remote id rule you have threeoptions, one is being connected to the internet via data to transmit the remote id. the second option is drones operate in a limited id mode where you are limited to 400 ft from you and the drone in any direction which is very very limited in terms of drone racing and free style. the last option is only going to FAA recongized identification areas or AMA fields which is a problem because there are not enough AMA fields or very little (also most tend to shun drone pilots because it gets in the way of their plane flying) which already limits the amount of space and fly areas the drone pilots have to go through.
so basically these remote id's aren't to benefit the hobbyist and it is more to benefit the commercial drone services such as DJI, amazon and other large shipping companies who may use drones in the future.
https://www.thedroneu.com/blog/faa-announces-drone-remote-id/ (https://www.thedroneu.com/blog/faa-announces-drone-remote-id/) a more summerized version of what the Remote ID proposal could mean for the drone hobby as a whole
again I apologize for not able to put a summary of what is going on.

Another thing that this also removes the current rule which is no drones below 250 grams can be flown without registering the drone. so remote id is tied to all drones regardless of weight limit. Before or currently we are able to fly drones sub 250 grams in our back yards and such without registering the drone.

Daily reminder its only a drone if it has some kind of autonomous flight capability otherwise its just a quadrocopter
the authorities dont understand this either
Usually its quadcopter but proper term is multirotor refering to an aircraft with two or more rotors example: bicopter, tricopter, quadcopter, hexacopter
stuff such as DJI multirotors can be considered Drones since they have some mission planning and obstacle avoidance.
but the FAA considers any radio controlled flying objects drones.
but the hobbies racing drones dont offer much in autonomous flight (some use gps but thats only if they go too far ahead to do a RTH function or send coordinates to your radio if you crashed).

Can someone help me find a good DIY drone build that will be ideal in stealing Amazon drone packages? Asking for a friend.
Thank you.

Actually, what about this drone for photo stuff too, Aryanne. https://www.powervision.me/en/product/poweregg
Problem with that is the controller it uses, not using a traditional radio control limits a lot of movement and it is very reliable. which is why a lot of AP platforms always recommend you use a normal style radio with two joy sticks to allow more control of movement.
though looks like this drone could use a trad radio, though I dont know much about it. As I am not as well versed in AP drones.

can you please explain the difference between a robot, a drone, and a complex machine? thanks
I was just being a dick. But really its the autonomous flight capability which makes a 'drone'. You could argue something as simple as station holding qualifies as well. I guess in reality it means most multirotors could be classed as drones, since even cheap flight controllers are generally getting smarter.
It just annoys me because 'drone' is obviously a scare word that exists in the discourse as an aftereffect of the killbot drone war in afghanistan from the last decade, and authorities are riding that same negative connotation now to get laws and rules passed styming the hobby, when the real objective is to make sure the 500ft or so flight deck remains clear for Amazon if they ever to their drone delivery thing.
i dont even fly multi rotors, i have a 300 size 4channel helicopter from banggood that id like to fly again when this virus bullshit is over, but this still affects me.
its something that amuses me because many nerds are very stubborn about certain things being "robots" and other things being "not robots", but none of them have ever been able to clearly define the difference for me. So, that's the difference I was interested in.
Technically, a dishwasher is a robot! Just kidding, she's a woman and she has rights.

dang, i should build one of these, this is really cool
Yeah, I really want to have some sort of autonomous boat for monitoring aquatic life at Wetfish's nature preserves. In the video he mentioned potentially doing a kickstarter to create a vacuum formed polycarbonate RC boat hull. That would be really cool because it would be clear so you could put cameras in the hull pointing down into the water.

it would be really easy to just do the vacuum form yourself. vacuum forming is super easy and can be done with a pretty simple setup

The kits are almost ready to order!!
He's been stress testing the design and it even works when driving on vegetation and sand!!!

i think it would be fun (but a lot of work) to make a dirgible lighter-than-air drone that doesn't use helium or hydrogen, but uses hot air. maybe one day scale that up too. idk if hot air lifts enough, or how to calculate this. like does it get more lift the hotter it gets???

I'm no expert in hot air balloons, but I did a few minutes of research and discovered that the amount of weight a hot air balloon can carry is in fact based on the difference between the temperature of the air outside of the balloon vs the air inside the balloon.
I found this ancient website that looks like it was made by a highschool teacher in the early 2000s which includes a calculator for determining the amount of weight a hot air balloon can carry for a given volume of air at different densities.
