    But, yes, it's easy to etch (ah, one of my childhood hobbies...)

    You need and etch-resist pen to draw out the tracks you wish to keep, and Ferric Chloride solution to etch the copper (nasty stuff - don't pour it down your SS sink whatever you do...)

    Results can be variable - the tracks can look a bit uneven, but as long as they are the correct thickness for the current being carried, then all should be ok.

    Photo-resist PCB can produce very professional results, but you need the software to design the layout, a printer to print it out onto clear acetate, and a UV exposure box...

    If you want it to look nice or if you need up to 4 copies of a not too big design then try the cheapy service at
    They'll make it for you for not too much money.
    It is very quick despite being in the States and the free design software is a pleasure to use.

    In my experience, etch-resist pens produced very poor results, with parts of tracks etching through. I suppose it depends how chunky your tracks are. I'd go the photo-resist route that Devs mentions. You don't have to use CAD software, there are other methods. I'm sure you would find a school or college with a UV exposure box. I think you can use weak caustic soda solution as developer, and just about any solvent as stripper.

    Don't let the ferric chloride get near aluminium!
