25 things to do before Aug. 25 – Edinboro University News Detail | 220v Contactor Relay

You’ll notice that there’s a single general lighting circuit that’s warmer than the other breakers in this panel; again, it’s only a small increase in temperature, so I’m not concerned. If it were much warmer, I might question why.

If I was working on your bedroom lighting and an outlet in your basement stops working a few days later, that’s just a coincidence. I’ll come back for the second project, but don’t expect me to do it for free because I “broke” it the last time. If I wasn’t working with that circuit, this new problem is unrelated.

99% of the time you can’t even begin to sue because fakes were often dumped and mixed in throughout the supply lines so it’s nearly impossible to track it back to the factory that made the fake. And even if you could find the original factory, international lawsuit rarely works out.

I love the concept and the build. But does potting with epoxy resin have enough strength to hold magnets in place? I did not see any mechanical fastners holding magnets in place . If epoxy cracks I see magnets pulling out of metal bracket and failure .Over to someone with engineering experience please.

Xiaomi has announced the Mi Mix 3, the latest entry in its series of full-screen flagship phones. It’s yet another high-end Chinese device with a huge screen-to-body ratio achieved by hiding the front-facing cameras on a sliding mechanism — no notch required. Unlike the Vivo Nex or Oppo Find X, however, the slider isn’t powered by motors. CEO Lei Jun compares the design to older sliding phones and suggests that it’ll be relaxing just to play with.

I’m surprised no one mentioned how Mattias Wandel mounted the SSR on a piece of sheet metal (pretending it will be a heat sink), then mounted it on a water _heater_. I know the heater is insulated so it really shouldn’t be radiating any heat, but wouldn’t it have made more sense to mount the SSR on the cold water inlet pipe? You want to heat the water anyway… When I saw his first video showing off the project I said to myself that’s not going to end well. I’m surprised it lasted this long.

Thanks for letting me know about the typo and qualifier on the 208V part. I’ve updated it in the article.

The Sony A33 includes an internal stereo microphone, actually comprising two separate monaural microphones located on either side of the electronic viewfinder / flash housing. It can also accept external stereo microphones, courtesy of a 3.5mm jack on the left side of the camera body. Alternatively, sound recording in videos can be disabled, if preferred. The built-in speaker in the Sony A33 is monaural, and there’s no manual control over audio recording levels.

I’ve built a 24 V heated bed for my DIY (as I call it) Mendel 90 XXL printer (400 x 400 mm print area). I use a 24 V 400 W LED power source and – since I already had a 12 V RAMPS – put a 24->12 V DC-DC converter in line with the RAMPS and driving a 24 V heating mat (for cars) via a DC solid state relay. As long as it’s not too cold in the room I get up to 60°C which is helpful for PLA but of course not sufficient for ABS (but I don’t want to breathe these ABS fumes anyway)… I’d rather use a thick cable (in combination with an energy chain) than playing with mains voltage.

I’d been “dead” 3 times at that point and thought I knew what it meant to be scared, seeing that tanker about to be filled, surrounded by thousands of litres of petrol, diesel, kerosene and other agents of flaming, painful death was and still is the scariest moment of my life. After that nearly being eaten alive by a feral pig or trapped under a hang glider under water was nothing

I recently spent 2 days troubleshooting my main PC because it was shutting down under even normal load, let alone trying to mine cryptocurrency. (I mine on my daily-driver hardware, not investing in a dedicated rig)

Back in the day the UK before EU harmonisation the nominal single phase domestic voltage was 240V ac and within a range of +10% and -6% ie 264V and 225.6 V Under EU harmonisation it is 230V +10% and -6% ie 256 V and 216.2 V. I can assure you that voltage control at Primary substations in the UK 33KV/11KV was lowered to the new nominal for the nominal voltage at secondary substations 11KV/415V/230V. A good thing really as it saves energy
