[Shop-talk] DC power supplay for home plating

[Doug Braun]

A few years ago I got a pretty nice
battery-replacement power supply from RS.  It has a
switch to select 3-4.5-6-7.6-9-12 volts, it is
electronically regulated (good for powering a CD
player, not so important for plating), can put out
800mA, and has a bunch of different style plugs you
could put on the end of the cord.

The part number is 273-1667.

They don't seem to carry this any more, but their
model  273-029 has the same output voltages, a higher
current capacity (1000 vs 800mA), and appears smaller.
 (Geek moment:  it is probably a switcher instead of a
transformer supply).  It sells for $18.99, which is a
good deal, considering that they are trying to get $30
for cell phone chargers which are simpler and cheaper
to make.

If you have a lot of electronic gadgets around the
house and shop, this sort of power supply can be very
handy.  It is almost as useful as an adjustable
laboratory or test-bench power supply, and costs much
much less.
