Homebrew PCBs

Didn't you have any problems to fix that heating element in the tank? Here in Belgium , the heater is supplied with 2 big suckers. They even don't fit in that tank! So , I had to fix the heater with some rope .... Time to etch a pcb is the same like yours.

          I've just etched a small board (ARM JTAG interface) using the new tank 
and it looks very nice. The instructions suggest two minutes to warm 
the solution after switching the heater on; I used about five minutes, 
and at least 20 minutes is probably about right. Because of the low 
temperature etching took about 15 minutes.

I used my usual photo-etch technique with artwork produced on an HP 
DeskJet 5940 inkjet printer using Premium JetStar film. The text on 
this board had the default 5 mils line width, and came out perfectly. 
Narrowest track size was 12 mils, though.

Here is a photo of the PCB:
