A pulsed DC adaptor doesn't have a filter capacitor, it's just a rectifier (often only half wave) and transformer but an unregulated DC adaptor does.philba said:as long as it's regulated.
an unregulated WW (often called "pulsed DC") typically has a symbol on it - a dashed line above an unbroken one. It's just a transformer, rectifier and filter cap. Regulated WWs will say "regulated" on them, it it doesn't, presume it isn't.

You can power an LED of an unregulated supply providing you calculate the series resistor using the unloaded voltage and I believe an astable 555 will also work but a monostable could have problems with false triggering.
