Breadboard Power supply

[Harry Bissell]

Hi Mitch (et al...)

<Flamesuit on>

Solderless breadboards SUCK !!!

they are only good for Electronics 101 class... where the tracher can tell
you why the
one chip inverting op amp you just built doesn't work. Likely a loose
connection.
See Bob Pease "SMWISICDT" (show me where it says I can't do that...)
porridge for
corroborating evidence.

Loose connections, too much capacitance where you don't want it... SUCKS

I use vectorboard and T-42 terminals which work for all non-SMT stuff.  Most
of my DIY are protos and they are so rugged that I have never had a failure.

I remember working for 10 hours in college on a solderless breadboatd... the
circuit was fine but the proto-board sucked !!! "Hey this thing works,
honest... it worked all day yesterday...really, it works...."

Actual mileage may vary. some folk like protoboards. I like to make a
connection and solder it. Then I know it is connected. and when I cut a
wire... its disconnected.

The battery hooks up just like any other supply... but batteries can deliver
AWESOME amounts of current short term (like short circuit). A power supply
with some form of current limit might be better for your use... then if you
exceed like (1 amp?) the supply shuts down.

Most chips (as you know) should not get very hot unless someting is wrong.
Usually the wrong pins connected to supply or reverse voltage. I won't blame
your solderless breadboard for that (yet....)
