Hello,

I've had my Copy Cad kit for a month now and have acheived some nice results. However, I find myself using more current than the specified 25 ma per square inch as this is the only way to get any visible bubbles. I'm using a battery charger set at 6 volts and 6 volt Radio Shack bulbs to control current.

Am I doing something wrong? Instead of measuring surface area in a precise manner and adjusting current accordingly, I find myself simply increasing the current until I get some bubbles. I just get the feeling that I'm winging it. Or are the specified current settings for a 1.5 volt supply and I need to do something different with a 6 volt supply?

Speaking of bubbles, what is the right amount to see?

Thanks,

Ed
