I am building a smallish project on a mini Breadboard (14 rows, 140 tie points...). I want to be able to power it from a Wall wart, and I will be using some micros (Attiny85) in it, so I need a steady 5V. I'll be using this switch-mode 9V wall wart. Since it is switch-mode regulated, do I need all the fuses and filtering caps on my regulator?
Or, in an effort to conserve space on the breadboard, can I get away with [u]just[/u] the regulator?
