maybe you could use the etchant as a wetcell in a battery and make a heating pad for the etchant with it and have its power level shown by a lit led.

RE: smloo

One would write 13.000 to provide 4 significant digits (rightmost digit in a number is considered suspect (rounding / measurement error) and therefore not trusted or “significant” – this way one is certain down to the hundredths place that the decimal part is 0.

Then again, it’s kind of hard to have “part” of a google result query, so specifying decimals for a count of google results returned doesn’t make sense in this context. ::shrug::

Ya, im agreeing with japroach on this one. you cant beat a 16 oz. bottle from a local ratshack for 7 bux of ferric chloride. theres no mixing of fluids, and if its a small enuf board you dont really even need to heat it, as long as its room temperature (so no etching in a cold garage).

“[edit] google results for “cupric chloride” etchant = 13100, not 13.000.”

A period is often used as the thousands separator in European countries. Why would anyone write 13_point_000? So just quit yer nitpicking and lighten up everyone! :-)
