Default Re: Dalo Pen replacement

I've skipped using pen and ink now. The thing that ended up working for me is quite fiddly but works well.

1. Get Tamiya masking tape
2. Clean the board with a pan scourer and let it dry
3. cover it with the tape, overlapping slightly.
4. Draw the design on the masking tape with any old pen (bonus it doesn't get finger prints on it now)
5. carefully cut round the traces with a scalpel and peel the rest off.
6. Etch as usual.

The tape doesn't dissolve in ferric chloride and you get really sharp traces!
