    Thank you very much for the interesting video. Is it possible to give part no of the transistor and diode please?

    Rick, How do i check the capacitors at the end of the IF transformers? Will the fact that they are connected to the coils affects a capacitance test? Thank you.

    A project of mine is going to use an RGB numeric display. I was puzzling over how to keep all the segments a steady color as the numbers changed and segments go out and come on. This is a delightfully simple solution!

    add a 10uf or larger electrolytic capacitor in circuit behind that 5v zener Diode & it will stabilize the 5volt circuit

    That's a very well designed & yet a simple circuit for driving the LED's. Thank you for that circuit.

    Can I use this to generate a 4 and/or 20 mA constant current source !? or How could I make it using 24vdc source and what components are necessary to do so !?
    Thanks in advance 🙂
