I just read Adam Seychell's page on various etching solutions. It seems to me that the only disadvantage to ammonium persulfate is slow etch speed at room...
The main disadvantages IMHO of ammonium persulfate in adition of what you say are : - It does not last long in terms of how many PCBs you can etch up until it...
... It needs heating 30 to 70C to get practical etch rates. Its not as economical as FeCl3 and other chloride based etchants. I guess some people use it...

Matthew, The way to do this in eagle is to: a) open your board in question. b) Mark everything and click on the cissors (Eagle does not have a cut, but cut...

The Pulsonix software I use has a step-and-repeat capability for output. Perhaps someone has written a ULP for Eagle that does something similar. Leon...

Anyone hack digital temperature control into a laminator? My GBC 9" laminator seems too cool for toner transfer and too hot for photofilm. I'm pondering...
Or you could simply use a thermistor, pot, transistor, and solid state relay, throw that together and be done with it. If you think about it, there really is...
... What's the working range for thermistors? I was thinking of using a MAX6675 chip, which goes from type K to SPI readout of degrees directly, with no extra...
If you plan to spend money, you could also get one of ebay # 250337695389 (Or any other commercial temperature controller, used one are cheaper as long as you...
