What is the province doing to ensure P.E.I. has a reliable energy supply?
One of the P.E.I. government's priorities is ensuring the province has a more stable supply of power. CBC News: Compass host Louise Martin asked Energy Minister Sidney MacEwen about the work he's doing on that front, and his confidence in shoring up more capacity.

i have been using it and it’s been fine

but it buzzes now

and also cuts out if you draw more than low power

note

THIS IS NOT THE POWER SUPPLY I FIXED BEFORE it’s different

anyway it’s rated for 10A but is dying being asked for intermittent 6.5

and nothing is obviously hot

so yeah

what’s it likely to be? power transistors?

Continuing on the "Hangell" switching bench power supply I received a few weeks ago...

I mentioned there was some switching noise visible on the output - not a lot, but more than I'd ideally want. Today I built a filter for its outputs, with a large-ish common-mode inductor/choke rated 10 mH (accurate enough, though my meter says it drops to about half that at 100 kHz) sandwiched between a couple of 1 μF class X2 safety capacitors.

It seems to have done the trick. Under a moderate load, all the random hash has disappeared, leaving only some spikes at the switching frequency, and those are much smaller than they were before. The RMS noise value is now (barely) under 1 mV, if you believe my cheapish oscilloscope.

Like a lot of switching supplies, there's a lot of open space in the chassis, so I had room to squeeze the filter inside. I'm pretty happy with it!

Now to see if this no-brand thing works for any length of time.
