The methods and chems I seek need to be cheap, easy to make & possible to make from readily available sources.
Salt, water & 9Volt batteries are cheap and the process to turn them into NaOH(+ H(g) & Cl(g))
with a salt-bridge electrolysis is really easy and NaOH is very usefull in many extraction methods.

Ethanol fermentation is easy. Get some yeast, lots of sugar and some tomatoe paste.(recipes available online). Ferment the stuff. Distill it. Fractionate it, Bang concentrated ethanol.
Yeah I have Ethanol on my list already as it indeed is easy to make & usefull in many extractions too.
I haven't heard of adding tomatoe paste to the yeast-sugar-water mixture before.
Does it aid the Yeast somehow? Or is it just an extra source of sugars for yeast to turn into Ethanol?

Vinegar has a similar method but no need for distillation. Just need a 'mother vinegar culture'. These can be bought online or at local places. This is how people used to get vinegar(so says my mom)
Thanks! Vinegar is defenitely usefull in extractions. Wikipedia mentions
Acetic acid bacteria
which ferment Ethanol into Vinegar. "Mother of Vinegar" is a culture of this
bacterium, right? I'll have a look around to see if I can find some.
Perhaps some professional cooking & kitchen gear store may sell it.
I'll defenitely add Vinegar to the list, but do you know anything about the
(easy) production process? Wikipedia is a little vague about it:
Wikipedia said:
Fast methods add mother of vinegar (i.e., bacterial culture) to the source liquid before adding air using a venturi pump system or a turbine to promote oxygenation to obtain the fastest fermentation. In fast production processes, vinegar may be produced in a period ranging from 20 hours to three days.
So you're supposed to add the Acetic Acid bacteria culture to a container
filled with ethanol(source liquid) & aerate that ethanol with air bubbles
until the process is done. That seems quite simple too.
Would an aquarium-pump suffice?

Ammonia can be made by bubbling ammonia gas released from the following reaction. Ammonium Salt(Ammonium chloride, ammonium nitrate, etc) and Sodium hydroxide, small volume of water to start reaction. Bubble the gas into cold water. Suck-back bottle is a good idea. Warning ammonia gas is very dangerous!!! If one starts from ammonium nitrate then they are left with sodium nitrate which can be used for nitric acid synthesis.
Nitric acid can be made by a variety of methods. The best one requires a simple distillation set up. Sulfuric acid and a nitrate salt distills over to be HNO3, leaving I believe sodium hydrogen sulfate a useful solid acid. There are easier methods but the concentration is usually pretty dilute and usually there are impurities. Warning nitric acid is a pretty serious acid, the fumes emitted in the process are NOx fumes(brown/red smell of chlorine) are very toxic and can kill.
Sulfuric acid from a sulfate salt is pretty routine in the electrolysis world. Here's a link about it.

Can you explain how Ammonia would be usefull in extraction? And from what
readily available sources would you obtain Ammonia gas?
Sulfuric acid may be usefull for extraction. That Instructable link is very
helpfull, but one thing concerns me:
Instructables said:
After the solution has gone clear, filter off the particles and the clear filtrate is dilute sulfuric acid that can be boiled down to obtain concentrated sulfuric acid. It will have trace amounts of metals but for most purposes this is not an issue.
Might these trace amounts of metal cause impurities in extracts?
Also: Isn't making & working with a strong, liquid acid like this
dangerous for uneducated, unskilled hobbychemists?
