Cheap emergency gold sockets

Stole this idea from Sijosae.. so I better share it...

If you need a socket and the shop is closed...
pull the pins from an old female d-sub plug....

There you go, cheap gold contacts...

Filed for future reference!!

These are the kind of tips that keep my projects rolling.

Cheers, Nordic.

I may never run out of miniature sockets (have plenty of salvaged ones) but recall that compactrons and Novar tubes have .040" (1 mm) pins as well...

I tried that waiting for acorn sockets to arrive and found the pins didn't retain tension well. A simple solution was slipping 1/8" of tight-fitting teflon sleeve over the sub-D pin before soldering, just enough to act as a tensioning band. Shrink tube might work too though not as well.

But can you add an LED to the base ?

Sonusthree · 11th February 2007, 05:16 PM

You can't get away with that Nordic!!!
What is it? (Headphone amp?)
What tube is that?
What supply does it run in on?
How do I build it?

and .... I know it's so wrong ....... but I love the LED idea.

Way too cool!

It might be worth pointing out that the pins on most pcb mount sockets do not line up with the pins on the tubes -- they are spaced wider. So, it looks like you designed the board with the eagle "tubes" library, and if you now try to fit a regular socket to the board, with a very few exceptions, it won't fit.

So, you may be stuck with the makeshift socket, and, importantly, someone with a board spaced for a socket who is lacking one likely won't get away with this trick.
