If you’re invested in the Alexa ecosystem, the Amazon Smart Plug is super reliable, dead simple to set up, and works with most electrical products you would find in the home. Be sure to heed the warnings found in the in-box manual!

I buy Crydom SSRs from Digikey. I pay the $40-$50 bucks, I use big assed heat sinks, and I sleep like a baby.

China is a shithole. Business-wise it’s like the West was 300 years ago, when your “flour” was cut with chalk dust and all the rest. Except apparently in Chinese culture it’s seen as enterprising and showing initiative, to concoct little wheezes like this for a profit, rather than the thievery our own culture for some reason sees it as.

Good call, light bulbs and heating elements don’t need perfect smooth precise 12vDC, as long as it’s in the ball park you’re good.

A properly wired, properly functioning dimmer switch can get hot to the touch. I’ve found that a 65-degree temperature rise is normal for a maxed-out dimmer. If the ambient temperature is 71 degrees and a dimmer switch is at 136 degrees, I’d be concerned, but I wouldn’t report the temperature as a problem.

Overall, there’s little question that the Sony A33 has the best video AF of any interchangeable-lens camera currently on the market, but if you plan on doing much video recording, I’d suggest you also plan on buying an accessory external microphone to record the audio.

Yup, switched off but still plugged in, that way the case is still earthed. Assuming a sensible 3-pin plug, or whatever the hell they do in places with just 2.

I’ve used 220V heaters to cook meat and I survived (quite well fed) up until now. I suppose heating a piece of plastic can’t be that much more difficult, although wh

Turn off the power at the main box to the A/C unit and open the electrical access panel on the air conditioner. It is usually located where the electrical power comes into the unit. Check for rodent nests and wires that have been chewed or frayed.
