Camera Flash Circuit and Nixie Tube Tutorial

Nixie Tube


In this episode Shahriar explores the principle operation of a camera flash circuit. The flash circuit is analyzed at the schematic level and through measurements. He then moves on to power a nixie tube using this circuit and calculates the efficiency of the DC-DC converter for this type of application. There is also a little quiz in this episode! Whoever solves the quiz will chose the topic of the next video.

    I really like your blog.. very nice colors & theme.
    Did you create this website yourself or did you hire someone to do
    it for you? Plz reply as I’m looking to design
    my own blog and would like to know where u got this from.
    many thanks

    Great video, Shahriar. Very clear explanations, good video quality, great content. Thanks a lot for sharing this.


  13. Jay says:


    Why is this circuit designed to charge the capacitor with the negative voltage of the wave? Would reversing the diode and large capacitor cause the circuit to then charge the capacitor with the positive voltage?

    Thanks for the videos!

  14. WestfW says:

    I think you can increase the efficiency some by removing the big capacitor. It’s not needed for a low-current application like a nixie tube, and will “leak” rather significantly at 10kHz.

    All in all, a pretty nice video…

    • Shahriar says:

      Thanks for your comment. I agree that the large capacitor is not necessary at all. It can be replaced with a much smaller cap which will have less leakage and would also reduce the charge time significantly. Some capacitor is needed however for the peak detector circuit to work.

  15. WestfW says:

    I don’t think your schematic in part 2 is quite correct. The 220 ohm resistor is in the wrong place.

    • Shahriar says:

      There are many variations of this circuit. The DUT I am presenting however has the resistor as I have shown it. I went back and double checked the PCB, one side of the resistor is connected to Vdd and the other side to the secondary coil of the transformer. Thanks for the link, lots of useful information there!

      • WestfW says:

        Ah. Never mind. I misread the upward wires as going to the 1.5V battery (+ and -), but they both go to the +1.5V side, and the other side of the battery is GND…
