In my experience, dimmable bulbs are no better. Most of them still suffer from the 120 Hz strobing effect. That's because even though they might PWM at 1-10 kHz to control the dimming function, when A/C voltage crosses zero, the &

Lifetime isn't even my #1 concern with LED bulbs. It's strobing/flickering. I film all the LED bulbs I buy in slow motion at 240 fps with an Android phone, and play the movie back on a PC with mplayer using the dot(".&qu

They certainly do. The 3-4 different Audis I have driven all have key cylinders in the door handles and a physical key in the keyfob. And you can start the engine when the keyfob is out of battery because they have a passive RFID built in

Nope, DW1000 can't work in an adversarial scenario. Their ranging algorithm critically depends on the receiver time-stamping the "leading edge" of the first bit of the first byte of the PHY header. This bit is either always 0
