How To DIY Elecro Etch Aluminum (Re-Uploaded)

[@TheMasaoL]

I would like to point out that if it were just distilled water you would be getting both hydrogen and oxygen gases. But since its salt water you will be getting chlorine gas forming on the positive terminal as well. Thats why when you had the polarities reversed your water looked kind of yellow. You were getting chlorine gas trapped in the bubbles.

Finally someone who has the polarity correct 👍 nope I spoke too soon. Electrons flow from negative to positive. What happens as the electrons leave the negative anode they take small parts of the base metal. It is essentially rapid corrosion.

[@hartfordboothe7466]

Cathode is negative, anode is positive.

Great video! What did you use for the mask?

[@theCybe]

This is the video I needed - thanks man!

[@CyberDenSystems]

You're welcome.

[@SunriseAt2008]

@CyberDenSystems look great! May I ask with what you cut the "black vinyl like stencil"? And how did you fix it to the aluminum? Appreciated!

[@MarcSmith23]

CriCut machine

[@ShayanQuanta]

I find difficulty about polarity. Where to connect positive and negative clips?

[@cafpcs7500]

Turned out pretty well!

[@CyberDenSystems]

Thanks man!!

[@jstrndm945]

Do we need higher volt to made deeper etch? Do we need to consider the amps also?

[@CyberDenSystems]

Not particularly. Higher voltage and amperage would just make it go faster. But, it would also get hotter and the fluid would evaporate faster. I set the current till it started to bubble, and kept checking on it till it was where I wanted it.

[@jonathanballoch]

time and circulating/replacing the salt water will help for deeper etc

[@paradox_sunflowers]

Do you not need stainless steel

[@pinepcdesign8459]

Wow, awesome dude!

[@CyberDenSystems]

Thanks homey!

[@ShayanQuanta]

It’s Look like Factory manufactured!

[@thraplomongo6766]

this is what I am looking for.....

[@brucecapron9344]

Cause you did not loosen with suitable solvent and heart my man
