Found another one of these lil guys from the agfa msc100 printer. Looks kinda "futuristic" even tho obsolete, but still cool...

Any idea what this component is?

Mon, 02/05/2024 - 10:22

Hey guys, I’m trying to repair a 12/240v 4wd fridge, and upon pulling it apart looks like a slug got in there and shorted it out. This 4 pin coil inductor thing has blown, with one of the copper wires wrapped around it being broken.

My question is - how do you replace these… can I just bypass it? 😝 I only mildly understand what an inductor does, and my limited understanding makes me think it’s not necessary.

This board is to convert 240v ac to 12 or 24v dc. Fridge works fine bypassing this board and powering on dc directly.

I can whack in a 24v power supply - but I’d rather replace / bypass this part if possible.

Pics of the slug and board attached - thanks in advance for any suggestions!

I just detected a real earthquake 😳

I just detected a real earthquake 😳

I just deployed 10 devices all over the city, to detect earthquakes.

All devices will send data to server in real-time.

When a device detect a shake it will look for other devices if they detect a shake too, when more than 5 detect a shake in the same time frame the server will send a msg to all my family members.

So there is no false alarms if someone hit the device or a truck passed a building.

This is my first detections for a real P-Wave happened today 300km away.

Old analogy gauges

Old analogy gauges

I was gifted a box of old analog gauges that I'm trying to figure out what to do with. They look so classic and we're probably great back in their time. Are they worth anything? Does a museum want them? Should I just make a giant display of gauges? Brands include Weston, Ti, Simpson, Honeywell
