I like the green CRT look. My photo diode TIA response with an elliptic filter looks good. This HP 3577A network analyzer is 40 years old and is still great 🙂 This machine has ports with 50 ohms or 1 Mohm impedance - selectable. Great for analog designs.

Today, I used Copilot to make a PRBS function in Python. Up to 7th order, looks fine. 8th order, no workie! FFT was not flat. Will explore tomorrow what happened. AI is interesting!

I like it when you add one more filtering capacitor and see a substantial reduction in noise. Neary done-done!

I got my cooling only TEC loop stabilized today. No H-Bridge needed! Laser makes heat, TEC just removes it. A fun controls project! TECs are amazing gizmos

My theory on the Air India plane crash is contaminated fuel. Most likely water in it. Perhaps sabotage? Who knows. We'll find out as the investigation moves forward. 0

I'm going to attend a No Kings rally on Saturday. I've never done this before. Might go to the big one in SF.

#UkraineRussiaWar Ukraine should put some drones in a passenger car or mini van in Russia. Strike some military targets. Watch the frantic search on every vehicle. An impossible task!
