Cheap but effective cable connectors to upgrade my projects

[LastSamurai]

Hi guys,

at the moment all my projects are using wires that are soldered on or these simple "arduino" dupont male / female headers/cables. As I am lately building a lot of my RGBW controllers and connecting them to my led strips via screw terminals and used speaker wire thats soldered on to them and just clamped into the screw terminals I am looking for a more "professional" solution.

What kind of cheap, easy to use connectors can you guys recommend, or what are you using?
I need some for smaller wires (e.g. to connect sensors to my boards) and some for bigger ones like the ones powering the led strips (I once saw some round cable ends that fit perfectly into the screw terminals but I forgot their names).

Thanks!

For some of my projects I use aviation style connectors like these

It's a pretty good connector for the price and is available with different number of pins

On the sensor PCB I always use dupont connectors

Thanks but thats a little expensive for me. Can anyone suggest a good and cheap crimping set for dupont cables?

PS I just found these, which might be great with screw terminals. Any ideas what female (or male?) adapter could be used together with this? Or what kind of crimping tool I need for these?

I own both the crimping tools shown in this video https://www.youtube.com/watch?v=3Cw9YFLDZeo and I agree with Andreas that the Engineer PA-09 is far superior to the chinese crimper when it comes to crimping dupont connectors. It also works will with JST connectors

@chrille Thanks, so a higher quality tools seems to be the better choice (like always^^).
Does anyone else have any ideas?
