Radio Shack PCB kit!

[Hal]

Everything you need -- two 3x4-1/2" copper-clad circuit boards, resist-ink pen to create circuit patterns, etching and stripping solutions, etching tank, 1/16" drill bit, polishing pad and complete instructions !!

For only $15 !!

Now, while I haven't made a PCB yet, I think this is the biggest ripoff ever.  the boards should be $2 each.  They sell just the echant for $4.  The "poslishing pad" is probably just a sponge.  I have a drill bit.  And I don't need a "tank," I can use a bowl or whatever.  The marker is a $1 sharpie.  So my final question is, what is "stripping solution?"  What is it used for?

I think that is the rubbing alcahol they give you to remove the etch resist ink...I mean sharpie ink.
It is the biggest rippoff. I know from experience.
The drill bit is kinda big too....never used it!
A burn nd a half!
Buy some PNP blue instead!!!!

haha yea, thanks.

I think I'm going for tonar transfer on my first try, though.  Wish me luck!  (don't worry, I probably wont actually start the project in about a month...)

What do you guys use as a "tank" (bowl) ?

What do you guys use as a "tank" (bowl) ?

A plastic storage container from a one dollar store.

I use the casserole bowl that my ex left. I really dig the little blue folwers on the side of it.

Hal--

Check out the photo-essay at Tonepad on how to use P'N'P blue. The process is consistent once you know the right setting for your iron, but getting to that point may take a try or two. Yes, a Sharpie (buy the Permanent type) marker from the hardware store is useful for touch-ups and filling in the occasional void. Denatured alcohol or acetone (also from the hardware store) will work as a solvent for the ink, and for many other jobs. Yes, avoid the RS kit, but the etchant is good and not impossibly expensive. If you need wire number drills (#59 and smaller), I have them. I will have more of the finer numbers on the new stock list that's coming out in January. A Scotch-brite pad and some Bon-Ami (supermarket) will be needed for preparing the copper surface of the board.
