Excellent presentation. The still pictures with labels help very much in detail seeing. Thank you very much. Your reverse engineering skills point out, that you are an innovative designer with plenty of experience.
If you want to have more whiteboard lectures after subsequent videos - I think many of us will appreciate it a lot. You’re a good teacher. Your videos already represent an incredible number of hours of reverse engineering, and to-the-point technical knowledge sharing. This channel is one of those gems hidden in plain sight. You have so much knowledge and I dare say there’s a few of us at least rather thirsty for it. I really appreciate all your work. And your hand-drawn schematics are a masterclass in how schematics should look. I wish you many fruitful years of disseminating of your knowledge, and may your health always be good to you!
Nice to see you in person. I watch many of your videos and is the first time i see an movie with you .
This is excellent. Thank you very much for all the time you spent on the whiteboard lecture. It’s very informative and well done. This is very valuable content - those electromechanical marvels are on their way into obscurity. It’s important that this knowledge is not lost and is easily accessible.
Very nice, great explanations.
Excellent video! This is the only place on UA-cam where this vintage and AWESOME technology is explained. You've helped my 747-300 cockpit instrument wiring by reverse-engineering some of the same instruments I use. Keep it up!
LSI is Lear-Siegler Inc., a pioneering manufacturer of aircraft radios founded by self-taught engineer Bill Lear in the 1940s (yes, this is the Bill Lear who invented the car radio, the 8-track tape and the Lear Jet).
Thanks for the lecture and beautiful clear, detailed schematic, an inspiration.
toujours super intéressant , un grand merci pour le temps passé et pour la partage c'est a chaque fois un vrais plaisir.
I really enjoyed the extended explanation.
Очень интересно. Спасибо.
Very great job, and very great explenation!!
Very interessing video, love the white board session !
Thanks fo the video!
