HI,
I am making a few boxed circuit. I am thinking of using a telephone
jack so I can communicate between two boxes ( I need 4 wires) Until
now it was good, telephone jacks are popular so they are fairly cheap.
The problem is that I do not have any square bits that fits on my
drills
I mean puncturing a square on the side of a plastic box is time
consuming Vs round. Especially if you are about to do 50+.
Anybody have a trick to make fast and almost perfect square. Or even
a round connector would be better, but I could not find any under 2$,
Its only for communication purposes,
Thanks
