  • High Quality (and Safe) Nickel Plating

    Hello, and thank you for this.I see many questions are going unanswered, but here goes!1. What is the optimum concentration to aim for with the plating solution?2. What is the optimum current density (A/cm^2) based on your most successful pieces?3. What is it about Cameo that makes it good for this purpose? Like lots of folks, I can't find it where I live.Many thanks for this Instructable!!!PS I think it would be great if you could add a section about safe and legal disposal of unwanted electrolyte. Can we treat it so that it can be safely disposed down the drain (eg by leaving a current running to plate out all the nickel, or is that impractical?), or should we allow it to evaporate to dryness, or just take it somewhere for disposal (where?) I understand that nickel is toxic and an env...

  • Scintillino - an Arduino-based Quick&dirty Scintillation Counter

    Thanks for this - very interesting and encouraging!Are you really seeing 400+ counts per second? Is that background?
