Just curious what the output looks like at, say, 80% of rated load.
I suppose the DC voltage may vary a little with load. I can measure that easily with a meter. But I'm wondering more about the higher frequency noise, which I cannot measure since I don't have an oscilloscope. Is it DC with a small ripple? Big ripple?
I'm planning a project using a spent brick as my DC power supply and I'm wondering if there is any concern with cleaning it up. I'll use a regulator to supply my control circuit (a 555 etc.), but will pulse the DC power directly into a transformer to get the voltage up (a wall wart in reverse, as an inverter). Can a brick handle that kind of loading?
