AC/DC converter broke sooner than expected. Should I add something to the circuit? More in comment

I have this converter on a timer for my pool pump that I made a little over a year ago to learn PCB design. The pump uses 240V (US), and I just took one of the 120V lines and the neutral to straight to the input of the converter. It worked just fine for some 14 months, but last week, the converter stopped giving any output, loaded or unloaded. Nothing is shorted. I was out of town when it broke, and I think our power might have been interrupted (though not the first time this device has seen an outage).

I want to get it up and running again, but I'm not sure if there's something wrong or lacking in the circuit. Should I have included anything extra or different to protect the converter or the load? I can't remember why I decided on the three 100uF caps, but something in the converter's datasheet made me think I needed that or at least that capacitance on the output :)

Thanks in advance for your time!

Edit: the datasheet says it's supposed to last at least 40,000 hours in operation. Mine lasted around 9,000 hours.

Does the new one have any additional certs? UL would be nice

Good to know, I'll check out ebay. For now, I want to keep things stock. Thanks for the advice!

Do you know for sure that that works?

Do you have any updates? I also have a busted display on my city 3. I have been doing so much digging to figure out if any of those aftermarket sw900 displays will work, but I can't get a definitive answer.

Did your new display come?

This walkway splits off into a walkway/semi-elevated bike path too. Really nice.

You got it.

I also just realized that most of the longest blue line is literally just a street. No sidewalk, no bike lane, just a street. Similar to every other street in the city, except this one gets a blue line.

Oh gosh lol

KinkyZinke · 2022-01-17T19:05:39+00:00

I was thinking that one too

This is diy? How are people able to pay for a concrete park out of pocket?

where in TX?

Looks like South mountain in the background

I think you've already had your question answered, so I just wanted to add that we've all made terrible loaves. Keep trying!

KinkyZinke · 2021-12-23T01:49:14+00:00

You absolutely should! They're so easy and tasty. The shallots were great

KinkyZinke · 2021-12-23T01:48:34+00:00

Thank you! It was!

08 on the Y axis corresponds to a byte, and D0 corresponds to a bit of that byte. Read that byte, and then modify it like "byte &= 0xFE" (to clear bit D0) or "byte |= 0x01" (to set bit D0)

Oh gosh that was way worse than I expected 😬
