Before You start
• Drill with 3 or 3.2mm (1/4") drill bit (for metal)
• Soldering iron (YES! solderless board need some soldering ;) )
• Xtaco or similiar knife with snap-off blade
• Accesory kit (provided)
• some color wires - I use parts of flat rainbow ribbon cable
• DMM with continuity test
• GP Crimping tool or flat pillers
Crimping DuPont connectors
Crimping is not a very complicated task - the best one can do is to get specialized tool for this kind of connector, but even hand tools cost a little.
What I"m using is GP crimping tool I"ve bought at my nearest shopping mall HW department - it costs something around $7 and has proven to be a very versatile piece of gear that I can use in my home.
Bottom line - money well spent, but you can get away using flat long pliers or jewelery making tools.
Below is short description of how I"m doing it - you may find it awkward, or inefficient, but it provides a good connection that will last.
Also, its worth mentioning that there are several sellers on eBay, that offer ready interconnection cables (query for "Dupont connector") for a dime - ie 40pcs for $4 shipped.
Do not separate pin from the feeding tape, use it to hold the pin steady while you are assembling the connector. Put some solder in between low and wide tabs (closer to connector socket end) of the connector. Try not to put too much solder in, you want the area between the tall tabs stay clean.
Strip .1" of wire from insulation material, and tin it. Then solder it to the connector. Do not to use another bit of solder at this stage, just melt the drop of solder already in the valley and on the wire together. You can use a small spot of flux to help the solder flow if needed.
Now is the right time to snap the connector off transport tape - it will break free after bending it back and forth a few times, right where the pin connects to the tape - no special tools needed.
Use crimping tool or flat pillers to close notches of connector. If you"re using crimping tool, then the rounded side of the tool cavity should point at notches, whereas flat side should be support for your connector.
This is how it should look like when you"re finnish. One is done, three to go ;)
