Nice job sir. Showing some EE skills there.

Thanks

Dude, hell f*n yes! This is awesome! Great job man!

[@samm928]

Mark, since you made that nice wooden box, you should have added a PAM8403 and get two speakers to the left and right of the tubes ..

[@TheElectronicEngineer]

Great idea

Awesome project. Thanks for sharing

Cool project for sure! :) Wondering how it would look like with the real deal stuff, and by that I mean IN-13 tubes. BTW "nixie" here is kind of a misnomer, since nixies were historically numerical only (that's where the name comes from), later on the family extended to all kinds of symbol displays - numerical, special symbols (like the measurement unit, sign or AC/DC in meters), segment displays. Basically anything that displays characters using neon (or other noble gas) glowing on a cathode bent to shape. So, I wouldn't call IN-13 nixies, since they're bargraph displays :)

[@TheElectronicEngineer]

You are correct….thanks for pointing that out

The video mentions not to use the same value variable resistors but I don't see any reference in the documentation was to what those two values are.

This is way cool! What was the cost of the board if you don't mind me asking? And you said it is available with small components already installed?

[@TheElectronicEngineer]

Yes pre assembled pcb is available. Please check the link in the description

[@notny41]

@@TheElectronicEngineer It seems like there should be more going on in the higher frequency lines. Normally the highs are quite dominant aren't they?

[@TheElectronicEngineer]

@@notny41 it depends. When using mic input, upper frequencies are limited because of the mic properties. Line in is way better

[@vmartins81]

Hi, great project, are you selling the project done or the parts for anyone to put together ?

[@TheElectronicEngineer]

Only the pcb
