Nice work! What techniques are you using? Photo, Toner Transfer, silk screening, etc?

Real excellent work. How do you make the silk screen?

One word concerning soldering of components:

Appearantly you cut the wires after soldering. It's better practice to shorten the wires before soldering. That way the cut off ends will also be covered with a thin layer of soldering tin preventing oxydation, hence longer life time of the entire circuit.

For equal wire length use a 1mm plastic or metal piece glued on the bottom blade of the cutter.

I was taught to resolder the pad (or reflow the solder) after cutting. Same difference I guess.
 

Thanks for the idea. Yes im using silk screens. Its time taking but its worth.

What did you use for tin plating? Or is that silver oxide?

Good question. I find that I need to look into some form of plating too. For hand soldering I sprayed a thin layer of acrylic after etching which prevented oxidization. But that does not work with hot air or heating in a oven or fry pan(sparkfun).

So what is the plating ?

The "plating" looks like photoresist thats been left on the board.

According to the manufacturers of the photoresist boards I use it can be left on as a conformal coating and soldered through but I've not had much luck doing this.
