When I build personal projects, I like things to be modular. You never know when the LCD you just wired up could be grabbed and used in another project… and wouldn’t it be nice if you didn’t have to desolder/cut wires just to re-position something tightly stuffed inside of your project enclosure? This probably explains why I end up making so many wiring harnesses and consequently crimping wires.
In the past, I used a pair of pliers and a soldering iron to connect these crimps to whatever wire I happened to be using at the time. This worked, but it was tedious and the outcome could have looked better. Why wouldn’t I use a pair of crimp pliers might you ask? Well, when I searched for crimp tools in the past, such as the ones recommended for JST XH crimps, they were priced close to $500! Absurd!
I think some of the folks at the hacker space still think I am a crazy for raving about these things as much as I have, but I just can’t get over how having the right tool for the job simplifies things. They let me crimp things easier (no more cursing as the crimp flies across the room), make stronger crimps (I hadn’t realized how critical it was to crimp the wire jacket until using these), and crimp way faster than before.
In particular, they are a HUGE help when you have to crimp lots of things at once. In my case, I needed them to assemble cables I include in SX2 Mini mill tachometer kits I put together. I was rather concerned about the time it would take me to crimp all of those connectors, but with the right tool it turned out to be a breeze.
Thanks to Bill from I Heart Engineering, we now have a pair of these crimp pliers for the space too! If you ever need to use them, swing on by!
