1. I have a need for a DE9 female connector without the metal
housing, something like
(
http://www.robotshop.ca/Images/small/en/parallax-basic-stamp-1-serial-adapt…).
I need quite a few of them, so I'd rather not buy DE-9s and rip
off the shielded housing manually. Anyone have ideas?
A problem with removing the matal housing is that often the insulator is
in 2 parts with the contacts held between them. Remove the metal, and it
all falls apart. I did once cut down the metal on a DE9 socket and solder
the bits togther to hold the insualtor/.contacts in place, but it was
a right kludge.
Last time I needed such connectors, they were to fit the joystick ports
on a Vectrex. At the time (this was some 15 years ago) there was a common
video game console that used DE9 sockets for the joysticks (Sega
Megadrive?). I rememebr buying extension cables from the local games
shop, cutting off theplug and and slightly trimming the edges of the
socket to fit the Vectrex. This cables had all 9 pins wired, I seem to
rememebr there was a similar cable that missed out at least one pin :-(
4. Anyone have a source for 28AWG 2 conductor
twisted wire?
5. If so, do they make it in 3 conductor?
When i needed twisted-pair wire-wrap wire (for modifying a DEC backplane)
I made it myself. Put a couple of reels of wire on a rod clamped in the
bench vice, then put the ends of the wire in the chuck of a wheelbrace
type of hand drill. Got a friend to apply a little backtenstion to the
reels and then walked across the workshop. When I had a suitable lengthm
I stated winding the handle. Didn't take long to get 3 twists per inch
(which is roughyl what yuou need for 100 ohm characteristic impedance).
I see no reason why that woudn't work for 3 wires too.
