Good Morning
It’s 57 out there with a high of 59 and more rain. Our 3 day total is 2-3/4”.
Yesterday started with taking pictures of an airplane to sell it for the widow of my friend that died. There are multiple prospective buyers, but I need an appraisal in this crazy market. Then it was back in front of the computer until I went out to lunch.
After lunch it was back to the computer until FedEx delivered my sharing station. That was a pretty easy install, as everything was prepped for its arrival.
So all I need now is the car to plug it into.
When I was at the airport taking the pictures,

I stopped in at the office, they had a contractor there repairing the runway lights, which are a new installation with LED lights. There was about a dozen lights out, the contractor said it was probably a lightning strike. Out of curiosity I took one of the failed lights home and removed the light assembly from its power supply, and connected it to the power supply on my bench. It worked, which supports the theory that the driver board was fried by lightning.
It’s an interesting system, there is a single high voltage (4kv) loop around the runway. Each light has a step down transformer with the primary windings in series, the secondary supplies ~120vac to the light assembly above ground. That is converted to low voltage DC to operate the lights.

I apologize for sharing my geekiness with those that might not be interested, but I bet I’m not the only geek here.
Today will start with breakfast with the professor, possibly wife and oldest son will join us.
Then back home to meet a couple of FAA inspectors auditing maintenance records. After that back to the computer and TSA, hoping to be interrupted that my car is ready to be picked up.
Zoe is asking for some attention now, so I’m going to indulge her..
