    etched in the basement.. the copper appearance single PCB was done with Toner Transfer, but my toner on the old HP was getting poor, and the 'generic' toner I used to top up wasn't quite fully compatible..pretty messy..
    factory toner in that HP [300dpi] gives half decent transfers at 16mi, maybe 95% acceptable at 12mi, to get consistent 12mi I should actually have a 600 dpi laser.. For most of my hobby stuff I run 20mi signal and 24mi supply widths..no screwups, quick results..
    The bluish set of three PCB's was photo etched, a little faster, cleaner, better quality, but more expensive.. probably $4 CDn for actual photo sensitized board cost for that size..
    Silkscreen is better for [me anyways] for quantities of 5 plus.. a little slower because of drying time, and probably the cheapest of all for larger quantities.
    The top placement overlay on the bluish ones was Toner Transfer again, useable but not 'professional' quality..
    I did a quick silkscreen with 160 on these, but 12mi isn't very 'neat', useable, but not really nice looking, need 255 or better for 12mi, I use 160 for 20/24mi and the quality is reasonably good..
    After all, this is just a hobby??

    enjoy..
