IVL1-7/5 Russian Vacum Tube (VFD) Clock - Part 1

I’m now building another clock with a IVL1-7/5. In fact, I’m preparing a large bench of VFD clock, and I need to test several stuffs, so the schematic isn’t public right now.

This one use quite the same stuff than my previous I IV-18 clock, the main difference is the VFD power supply, but if you read this weblog, you will understand easily. I will publish the whole design and source code for free soon.

Anyway, here some pictures:

Soldering SOIC isn’t that hard ;)

The VFD tube is really big, and nice no ?

As you can see on the latest picture, there is a little gradian due to the filament supply. I haven’t find a simple to use (as the MAX6921) VFD driver that support AC filament. (MAX6931 is to small for hands soldering)

Enjoy :)

    Hi jkx,

    I created a link to your image (DSC02528.sized.jpg) to show people that visit my site what a VFD display looks like. I hope you don’t mind.

    Kind regards,
    Lex
