Oh the ones from BPS space are even more impressive with adjust on the fly tracking to 3D points and launched from a VLS he made himself.

Safely? Yes.
Keep the reaction stirring under ice and if you see the temp rice above 15 C you dump the whole thing in a water bucket or you get a runaway exothermic reaction that is never good with a high explosive forming crystals in the solution.
If you are stupid, don’t ventilate, or are stupid stupid it will light your shed on fire and potentially kill you.
That’s why you work at lab scale, and why you always keep your reactions under the temp limits with acids added slowly.
Basic chemistry safety covers all the bases here.
My preferred blasting caps are nickel guanidine based. I can play with the crystal morphology to produce small more friction inert powder and it is an extremely simple synthesis.
You can use reloading press combined with highly suggested lexan sheet as a blast shield and wooden block to gently press the powder into caps. China sells packs of 1000 electrical ignition assemblies for $40 that you can then set off with a COTS or a clacker.
I cannot emphasize enough that working at small scale and knowing what you are doing are important, but in faster time than it takes to print the parts for that drone you can absolutely complete the reaction, do some recrystalizstion, dry your product,and be ready to mix with plasticizer.

I synthesize energetics. I can make a primary explosive that is stable enough for cap usage with a solo cup. I can synthesize secondaries like RDX above (one of the more complicated common ones) in short order with a basic chemistry set and the internet to order basic reagents. None are controlled substances.
It is trivially easy to make effective shapes charges and energetics at home.
Synthesis is federally legal in the US so long as you do not assemble into a device or transport. You can do both with an SOT as an FFL.
If I wanted to, I could make a shaped charge that was point imitated and base detonated for the above projectile and it would punch through about 1.5 feet of homogeneously rolled steel.
The limit to threat is not the access to explosives, as the chemistry and processes are published freely online as easy to replicate. The drone parts and control surface actuation is by far harder and I say this as someone who has a professional background in computer science and software engineering.

I work on side projects for people with woodwork.
My day job that makes up the majority of my income is in software.
I wouldn’t call myself a woodworker over a software engineer.
You are calling yourself a content creator instead of a prostitute when that’s your primary profession. Nothing wrong with either profession, but that context is relevant.

Octopi if the base word was Latin. It’s Greek, so octopodes for plural. Technically.
Because English is a bastard if a language octopuses and octopi are fine too.
