So here follows the first in a series on how to approach electronic devices containing high voltages, and live to tell the tale. By “high voltages” we mean anything up to mains voltages, and those directly derived from them such as the few hundred volts rectified DC you’ll find in a switch-mode PSU. For multi-kilovolt EHT you’ll have to wait for another article, because that is an entire subject in itself. We’ll mention these higher voltages in passing, but their detail is best left for a Hackaday colleague with more pertinent experience.

Wonder how long it’ll be before Toyota marketing changes Aygo to Starlet, the Yaris to Tercel, GT-86 a Celica and CR-H a Space Cruiser?

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

But even so, you’re not likely to be arrested for adding your own electrics, I dunno that it’s actually illegal. Charging money for it would be different. But I can imagine insurance companies would hold it against you. Any excuse, of course. You’ll have to check the teeny-weeny print in your policy, and the extra documents they didn’t send you. But it’s not impossible for someone to fuck up mains wiring and burn their house down, and that would be their fault.

If you look at the Fotek datasheet for that relay, you’ll find that the specified heatsink does not resemble a piece of galvanized steel sheet metal, horizontally mounted with a half inch air gap under it, and set on top of a heater.

400 Hz is the frequency of choice for aviation. That’s why the PA system in airplanes has *that* particular background tone in it.

FYI: The bare minimum requirement is AWG #20 wires for chassis wiring 11A which is what’s needed for 100W at 12V. I wouldn’t exactly call that a thick wire. While you can get away with using thinner wires fopr the AC heater, but you’ll need the wire to be able to carry the current defined by your fuse and have thick enough insulation for the voltage rating. So at the end of the day, the overall diameter for the AC heater still ended up being thicker.

Haven’t really looked at how the eBay feedback system works these days, but is it still the case that if a buyer gives a seller a negative no matter how well deserved, he can pretty much expect a negative in return?

For example, you can assemble a computer and do anything you want with the low-voltage parts, but opening the PSU and fiddling with that is illegal in many parts of the world. IF the device later catches fire and the insurance company finds out it was modified by yours truly, they can deny coverage, and if your neighbor’s house burns along with yours they can sue you etc. etc.

Only thing I can think is that it will send more current to high resistance loads like a human body, where lower voltage will send less. That’s the only thing inherently more dangerous about higher voltage, no?

I get called in all the time for problems with space heaters. If you leave the house while the heater is running, the connection could get loose and burn up the plug, which could start a fire. Give your space heater the space it needs, and turn it off when you aren’t using it. Learn more about how to use a space heater safely.
