    this video is so underrated, I've just found it a couple of minutes ago because a random recommendation, I'm very excited to learn this, I'm just barely started the video but I'm pretty sure I'm going to learn some great stuff, must check after this other videos of you.

    This is an extremely useful project. Thank you for spending the time to produce it for us.
    Cheers

    Amazing video. I was looking for a cheap, but precise voltage reference option. Thank you for sharing this!

      Thanks Zoltan. Its a very convenient standard still very much in use by me, even though I since bought a couple of other voltage references. Those are 5V or 10V and these voltages are often too high for a good resolution on cheaper multi-meters. The lower voltages like 1.024 and 2.048 in particular are perfect for checking accuracy of 2000-count multi meters.

    How not to give a thumb up!

    This is very cool, congratulations! I like it as it is simple.
    I have built recently a programmable voltage source. See my latest video.

    Tl431с усилителем тока можно взять за основу.

      Yes no doubt. But at the time I had this Adafruit LM4040 reference laying around and this looked like a good way to use it.
