Matt Millman writes about electronics hobby projects, connector types and crimping, vintage networking, and PC hardware quirks like PCIe bifurcation.
Commenters call his connector pages one of the best resources available, citing the JST and DuPont guides, which also warn against crimping DuPont connectors as a hobbyist.
I wouldn't recommend crimping your own hookup wires as a hobbiest, especially not dupont. The unofficial tools for dupont mostly all suck, and the official tools are $400+[1].

For my own crimping of dupont, I'm using the Iwiss SN-025 which works OK, but even then I've mostly switched to Mini-PV because I was tired of the dupont receptacles wearing out after 5 cycles.
The pictured SN-28B is definitely not good for dupont, which has a totally round cable holding ring. Amazon/Aliexpress sellers don't know anything about what they are selling.
Here are some more links on those controllers and various LCD data:

I will often spend hours researching different kinds of electrical connectors instead of....any other thing that I'm actually supposed to be doing. If I am feeling extra depressed I'll go order myself some Anderson PowerPole housings or maybe a kit of aviation connectors. Or read http://www.mattmillman.com/info/crimpconnectors/dupont-and-dupont-connectors/ yet again.
Not an EE but I know exactly what I'm going to use these for: Playing with old CPUs so that I can implement all the bus and decode logic and some peripherals in it. Something like this[1] but even simpler. They'll probably be used for similar but more realistic stuff, i.e. as reconfigurable glue.

Much great info about JST connectors, heck the whole website is great:

These tiny connectors absolutely must be used with a proper crimper.
