Things Your Electrician Wishes You Knew | 19mm Momentary Push Button

I first thought we were about to see the actual moment when it was about to blow. But this is post mortem autopsy.

“I don’t think” – hehehe I’ll agree with that. My utility company provides 3rd world electricity in August. Most days the juice drops to 103 without anything on in the house. I’d love to have as much as 110. Fortunately, the L1 car charger works down to 100, and the L2 stuff works at 187 – the lowest I’ve measured. 5 big reasons why the juice is so bad, but then I’m not paying for the loss, so its not a biggie with me. Just worry a bit about the refrig and freezer.

Maximum video length is 29 minutes or two gigabytes per clip, whichever limit is reached first — although if SteadyShot is enabled, this limit is slashed to just nine minutes per clip, likely due to sensor heating issues when using the sensor-shift stabilization mechanism. Full HD videos are recorded using 17Mbps AVCHD compression, while the lower resolutions are saved with MP4 compression, at a bitrate of 12Mbps for 1,440 x 1,080 pixel video, or 3Mbps for VGA video. Movie capture is started and stopped with a dedicated Movie button located just to the right of the electronic viewfinder, within easy reach of a thumb press.

The guy on final test stood on a rubber block but still used to get blown across the floor once a month

For example, putting 1 mA through a 1 MOhm resistor requires 1000 Volts. The current itself is barely noticeable and if it’s high frequency current you’re unlikely to feel pain – it’s just a funny spark that kinda tickles at your fingertip – but it’s still depositing 1 Watts of power into the resistance.

The AVIC-W8400NEX flagship has a 7-inch capacitive touchscreen, while the AVIC-W6400NEX has a 6.2-inch capacitive touchscreen, and the AVH-W4400NEX has a 7-inch display with resistive touch capabilities. The receivers support both Google Assistant and Siri and can operate wirelessly via Bluetooth, Wi-Fi, or wired through a Lightning connection. Additionally, you can control your smart home devices through the units, including things like a garage door, locks, or lights.

Yes, agreed, actual power supply design must take into account the allowable possible range of input. My house nominal “240V” supply routinely hits 252V, for example, and is allowed to go as high as +6% (254V).

You neglected to mention the Geiger-Muller counter and the Anthrax detector. Nothing short of criminal negligence to work without either one.

I have been led to believe (largely by bigclive) that Fotek are OK but there are lots of fake Foteks out there.

Most significantly, today’s Corolla arrives sat atop the Toyota New Global Architecture (TNGA), a complex name for underpinnings that, in this form, have already demonstrated considerable promise in cars such as the high-selling CH-R SUV, hybrid Prius and soon-to-be-on-sale Lexus UX.

Step 4:  Use the V-I curve (Fig. 3) in the MOV’s datasheet to verify that leak voltage will be less than the 300-V ceiling.
