title_body: Affordable ways to crimp your own connectors Ever since PX4 and DroneCode came up with their connector pinout standards. I see more and more sensors and devices off the shelf adopting the same
  This is particularly the JST-GH and Dupont connectors
  
  
  
  
  I like to make my own cable harnesses (So that the cabling is clean and easier to debug) but I'm having trouble finding cheap ways to do my own harnesses now. Does anyone know how to crimp JST-GH connectors cheaply?
  Here is my setup (which I don't like just because of how expensive it is):
  
  Dupont:
  Pins and housings $10
  Amazon link
  
  Crimper PA-09 $40
  
  I find that it's easy to buy SN-28B style crimpers for DuPont connectors but those are garbage. I do not recommend. I will try the IWISS $16 and report back.
  
  JST-GH:
  Pins, only one kind $0.11 each
  Digikey Link
  
  Crimper YRS-1590 $1239
  Digikey link
  
  This crimper is awesome, it works like a machine gun, you load a reel of pins and you can go to town crimping left and right. But it's soo expensive! 
  Anyone know of better options?
upvoted_answer: I crimp my JST connectors using needle-nose pliers. It’s probably not be best way to do it, but it’s cheap and works well for me.
  
  Place the wire with the stripped end in the metal connector piece.
  
  Squeeze perpendicular to the tabs on the connector with the pliers.
  
  Now squeeze parallel to the original direction of the tabs.
  
  Finally, squeeze perpendicularly to the original position again.
  
  Give the wire a tug to make sure it is held securely.
  
  Like I say, probably not the best way and I can’t vouch for how reliable it is, but it hasn’t let me down yet.
