Speaking of LEDs...

--I've been looking *everywhere* for a specific kind of connector but I
can't seem to find any. Ya know those long snap-apart 'sticks' that have
male leads on one end (that can be pushed thru PC board holes and soldered
on the back side) and female sockets on the other? I've been able to find them
with the tiny, circular female sockets but I can't seem to find any with the
*square* female socket, like what you'd see on a proto board. What I'm trying
to do is populate one of those evilmadscientist boards with interchangeable
LEDs. The trouble is the square lead variety; i.e. the common, cheap ones,
don't fit in the little round hole connectors. I found one outfit that will
sell me a two-pin connector like I need but their price was astronomical!
--Has anyone got a source for these in the snap-apart form, with
a 2.4mm (0.1") spacing?

Why not try it the other way around?

That is, populate the board with headers and use 2 pin female
connectors to hold the LEDs.

You can crimp or solder the square female pins to the LEDs, push the
pins into the housing and you'll be done.

Just about anything that makes a reliable fit to a 25-mil contact will

work sorta OK for an LED as long as it's for experimenting, not for a
product or high vibration environment.

Look in the DigiKey catalog for 100 mil spacing 25 mil square male
headers. Somewhere nearby, on one of the pages, there'll be matching
sockets.

I'm doing some work with that particular combination right now and I
have the following part numbers in my notes:

57052-ND
57053-ND
S1012-19-ND
S1012-20-ND

One or two of these should help, probably not designed as snap-apart,
but possibly as an economical 2-contact or something that you can cut
apart yourself at the cost of raw edges and one lost contact at every cut.

Or try the usual surplus and semi-surplus places -- All electronics,
MPJA, Jameco, etc.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

I'd just get a cheap (folded sheet metal contact) DIP socket and
hacksaw it into two rows, OTOH DIPS with square pins do fit the
machined-pin DIP sockets too, so LEDs should work there too.
