My original quote is based on the project you called me in for. If I find out there’s actually a larger issue at hand, I’ll need to increase my price to match the scope of the project. I’m not ripping you off, I’m just making sure I get compensated for the extra work.

”Just like with laptops and mobile phones, sophisticated new features sometimes require new hardware,” Sonos said in its blog post today. “The computing platforms and software architecture in some of the older Sonos players simply don’t have the horsepower to support AirPlay 2. But by taking advantage of newer Sonos hardware, we’re able to make AirPlay 2 content available throughout the house on speakers old and new.”

Power outlets in homes—but not businesses and other buildings—are required to have tamper-resistant receptacles, which prevent kids from getting hurt when sticking objects in the slot. At first glance, the tamper-resistant receptacles don’t look different from the ones without the safety feature, so read the label closely if you need to buy a new one. They’re a little more expensive, but I’ll send you back for another if you don’t shell out the extra money up front.

This is overkill. You don’t need a safety-ECU for this. It is much safer to use the thermal fuse(s) you mention and they are sufficient. If the safety can done without CPU intervention, then do it. 2mil Kapton may have this standoff voltage, but it is scratched easily. I would bond the (high-tg FR4) PCB heater with silicone to a glassplate (pyrex or something).

I to have worked with high voltage systems. My point was that it needs to be treated with a bit of respect or it WILL kill you even if not immediately. My friend was an electrician of many years. And sure, I hear lots of stories of how people get away with this and that, but that is just that they gotten away with it so far. They could be dead tomorrow.

Once got electrocuted from a computer monitor though, that a relative thoughfully gave us without a case. I was reaching underneath to adjust the brightness or something. Touched something live. The monitor was on the floor, with the 8-bit computer (a Spectrum). My hand touched the live PCB, jerked away, bounced off the floor, and back up to the PCB again. Eventually my sister switched it off at the socket. Bit stupid really, I wouldn’t let kids near something like that, but…

“180 bolts per second”? Now there’s an engineering unit I’ve never encountered in more then 50 years. No, it’s just a 150-180 volt sinusoidal or square wave at various frequencies. In past years, the coil on the bell was mated to an appropriate capacitor to allow ringing a specific phone on a “party line” based on the ring frequency. It was amazing stuff for a time when they simply hadn’t run enough wires for all of the individual “private lines”, so they had to engineer very basic things to fill the need. It was in a sense, the most basic and pure form of understanding the physics (electrical and mechanical) hacking.

In air conditioning, we are given a gift by equipment manufacturers on the equipment data tags: the minimum circuit ampacity (MCA) and MOCP or max fuse/max circuit breaker rating.

Although a mains powered heated bed sounds scary for a hobbyist-built 3D printer, there are a number of positives to the design. It would heat up faster, thin down a few parts, and significantly reduce the overall cost of the printer by not requiring another 100 Watts delivered from a 12V power supply. It’s a great idea if it doesn’t burn down the house. Anyone want to help?

I’ll try to fix your old item if I can, but I might ask you to have a new replacement on hand just in case. Don’t skip the shopping trip because you’re banking on me being able to fix the old one. If it’s beyond repair, I’ll need to come back (and charge you) for a second visit once you get to the store instead of finishing the first time around, ultimately costing you more. You’re better off buying it and returning it if we don’t need it. Just don’t bother with these 32 home upgrades that are a waste of money.
