[TriEmbed] Power Supplies

[brian mueller]

I definitely second that! It will definitely save you some time in the long run if there's ever a problem. Had it happen before, big waste of time!

 I still have a protoboard that
 has a melted spot in it from an exciting event with an over
 powered unfused supply. I shorted + & - 12 volts across
 a 741 op amp. It split the 8 pin pdip package in half &
 sent the top half up to the ceiling from bench height,
 leaving a tiny burn mark there. 
 
 Ah college....
 I would definetly put a fuse in there.

 A supply with lower current might be smaller and perhaps
 create
 
 fractionally less heat. If there was a safety issue with
 having more
 
 current than necessary (though I can't think of one at
 3A), you could
 
 always put a 500 mA fuse between your supply and project.
 That would
 
 limit damage in the event of a short.
