wear gloves

stir frequently

heat helps like setting your etching tub in hot water, never heat directly

you can fix toner transfer issues with about 3 coats of sharpie

any new ideas ?

You could do your own single-sided serial arduino.  See the main page here: http://arduino.cc/en/Main/ArduinoBoardSerialSingleSided3

Regarding your etching, I'd try this method: http://tanjent.com/doku.php?id=pcb_fabrication

that was the thing i wanted to try out and will there be any disadvantages of this when compared to the readymade board?  :-/

I have Build 3 Single Side boards.  I had to modify the board menu so it said SEVERINO with AVR328... but otherwise there seems to be no issues with the Single sided board.  It's fine and fun to make.

I also have been using the EXACT METHODS from that GOOD LINK on fabrication.

i would be really glad to know how to do it  :)

Well, do you not know how to start?  Do you have some copper clad board?

jada

:) i just ordered some copper clad board and fe2cl3  ;D and the atmega
and pillward could you let me know how to modify the board menu or atleast give your modification  ;)

Use sunlight instead of a UV chamber. Much cheaper for just one board!

Rather than just "toss you to the wolves" and give you my file... here is HOW it's done.

And who needs UV when you can just use Toner?

is this step compulsary ? i mean what if we dont modifi i guess it is just changing the baud rate waht help does that do
P.S i am not so clear as to why should we change it  ;) will it work if we dont change





jada

Hi,
Finally i tried it Today ( Exams wouldnt let me do it then )
the toner dosent stick to the copper clad board im using pohto paper with Cannon Lbp 2900 laser printer i tried it thrice! but no Sucesss :(

I was just wondering about the same process, and I found this handy instructable on a solution you can use to etch infinitely. The solution is also very cheap to make, and has less environmental impact.
