Microsoft announces Xbox One keyboard and mouse support with Razer partnership | 25 Amp Circuit Breaker

I would build a custom circuit board, and not use soldermask on the heater side. Instead, I would bond a sheet of pyralux on the face of the heater. Pyralux is Kapton with integrated thermoset acrylic adhesive on one or both sides. 2 mil Kapton has a voltage standoff of 10KV, so electric shock would not be a problem. Bonding can be done in a standard oven using metal plates and clamps (to apply pressure), or with a special heated press.

With the nation’s network of public electric vehicle charging facilities still relatively thin, most EV owners charge their rides at home. This can be as easy to accomplish as plugging the car into a wall outlet or as complex as having solar panels installed to replenish an EV’s battery.

We recently had a chat among the Hackaday writers about how we could approach this subject. The easy way out is to be all Elf-and-Safety and join the radioactive anthrax crowd. But the conclusion we came to was that this site is a resource for hackers and makers. Some of you are going to lift the lid on boxes containing significant voltages no matter what, so we thought we’d help you do it safely rather than just listen for the distant screams.

The standard in UK is 230 V not 240 V, like the the rest of the EU. The continent was mainly using 220 V until 1986 and UK 240 V until 1986. The 230 VAC was choosen by the IEC as a compromise between the 220, 230 and 240 system. So actually main voltage in EU should be 230V +/-6% at distribution panel, and equipement should support 230V +/-10%. (voltage drop in the internal house distribution should be less than 4%) But a transition period of 20~25 years was used, during the transition period main voltage at distribution panel in UK should be in the 230 VAC +10%/-6% range, and in the rest of EU it should be in the 230 VAC +6%/-10% range. (Other 240 VAC country like Australia and NZ switch to 230 VAC at least officialy)

Snap! Didn’t even get the first instrument lit. I began to investigate. Wiring size, check. Dimmer output side breaker, still on. Go further down the line and find that the electrician had indeed taken care of it. He re-did my calculations, which at full nominal load looked like a 15 amp breaker on the input side of the dimmer would work just fine. What they didn’t realize is that when you bring an instrument or instruments (depending on the circuit) to full on, you go beyond even 20 amps for just a moment, then it goes down to about 13 amps.

The Death Star post illustrates why we shouldn’t let economists decide how to run things. That and a million other stories from real life.

This plate is too likely to touch the user. It’s sensible to have a certain fear of mains voltages, makes you pay attention when you’re working with it. The DC power suggested would come from the printer’s existing PSU, pay a little bit extra for a few more amps, the overall wattage isn’t high. Much less than I presume you’d use in industry. Thanks to power-hungry graphics cards, high-power PC PSUs are cheap.

A clean filter is vital to a well-functioning air conditioner. During the summer it is good to check your filters once a month. If you have pets, leave windows and doors open, or have allergies, you may need to change your filter more often.

The device uses two hot and one ground to supply the 240V output which is, in some business where there is three phase power this will be closer to 208V but should still work. Obviously you shouldn’t be doing this unless you know exactly how it works, and we applaud [Nick] for airing these hazards while at the same time supplying the knowledge behind the concerns.
