Homebrew PCBs

Hi all,

WOW, what a difference a little bit of practice makes and a new 
etching tank.  I posted images of my latest attempt in the files 
section - root directory.

Process outline...

Designed in PCB Wizard
Printed on Pulsar paper using HP laserjet 6p
Transferred with iron, two 15 second pressings @ 360 degrees F
Etched in ferric Chloride, warm, with air bubbles.
Wiped off toner with Acetone

And that is what you see.  Next up, I will try the tinning process 
using solder paste as outlined here about a week or so ago.

I am amazed at how much better these came out compared to my 
previous attempts.

The change in transfer was shorter pressing time (was about 90 
seconds or more) and perhaps a bit less heat, didn't measure temp 
last time.  Also, made sure to re-position iron during pressing so 
as to make sure the steam vent hole areas would be re-pressed with a 
different part of the iron sole.

I used ferric chloride last time, but in a small tray with gentle 
rocking for agitation.  This time, the tank is much larger 1/2 
gallon and am using fish tank bubblers for agitation.
