    I had no idea that Canadian bills have such a hologram feature; very cool!

    Hi, I really like your videos with RF stuff and I also like chemistry so it would be really great if you show a few such experiments!

    Hi Shahriar,

    Very interesting video.

    Specially, the PLC, the PCB strip wave guide and dollar bill – again says how the science and mathematics are used in every application.

    Eagerly waiting to see detail review video of *Signal Hound SM200A spectrum analyzer*, which is sitting back side at the end of video 🙂

    Thanks & Regards,

    Hi Shahriar,

    I really enjoyed your Five Interesting Things video. The attenuator and the wave guide were particularly interesting.
