Is there a site somewhere with comprehensive drawings of everything in SMD packages? I have an SMD LED (APA102) and going nuts finding the art for the PCB. Wasn't shown on the datasheet. I think it's a 5050? (Not familiar). Is it just me or were internet searches much easier 20 *^$&ing years ago? :)

My understanding is that utility meters measure instantaneous voltage and current (simultaneously) at a rate much higher than the AC period and use the sum of the products over a time period (typically a multiple of the AC period) to measure power. Then apparent power is calculated (if needed) by calculating the RMS of each the voltage and current over the same time period and calc

If its water based, it will likely freeze if left outdoors in cold weather. For example, your car radio has caps, and if it's parked outdoors in the winter, the caps in it will freeze. Yet, I have never found my car radio working poorly in cold weather. This ma...

Hello, Today I bought an SPDIF-optical/TOS link cable to experiment with soundblaster to receiver audio processing options.
