Discussion Overview

The discussion revolves around the process of depositing thicker layers of copper on glass using a DIY electrode cooling system. Participants explore the technical challenges associated with maintaining current through heating elements and propose solutions involving cooling methods.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes their setup for depositing copper, highlighting the need for cooling the tungsten electrodes due to high current levels.
  • The proposed solution involves circulating cold water through the electrodes to manage heat, utilizing inexpensive materials like a styrofoam cooler and a small fountain pump.
  • Another participant humorously comments on the setup, likening it to moonshine production, while also acknowledging the effectiveness of the cooling system in achieving thicker copper deposits.
  • A later reply references a fictional element, the flux capacitor, suggesting a playful tone in the discussion.

Areas of Agreement / Disagreement

Participants generally agree on the effectiveness of the cooling method for depositing thicker layers of copper, though the humorous comments introduce a lighthearted debate about the nature of the setup.

Contextual Notes

The discussion does not address specific technical limitations or assumptions regarding the materials or methods used in the cooling system or deposition process.

I wanted to deposit thicker layers of copper on glass with the deposition system I put together, meaning I would need to keep current flowing through the tungsten heating element longer. But with 70 or 80 amps @5 volts, the electrodes wouldn't be able to survive the heat generated. So my solution was, circulate cold water through them. Very simple and cheap. One small cut-down styrofoam cooler, small metal "pot" ~2 1/2 cups, some plastic tubing, a small fountain pump, and ice. Here's a couple of pictures; the electrodes being cooled and the circulating water chiller.

Looks like you're making moonshine to me... :biggrin:

BTW: This thing works really well. I've been able to deposit really thick layers of copper on glass now.

Yes, flux capacitors do need a pretty thick layer of copper.
any chance of showing the pictures of the deLorean out back.
