Homebrew PCBs

I sell direct etch resist kits:

As I sell both products I am familiar with capabilities and UV curable ink
is a superior solution.  You need to dry the ink which is a somewhat time
consuming process and UV ink is much harder.  I will show some results when
I have time to etch.

HP 45 original ink is pigment based:

But there is authorized UV curable inks inside HP 45 carts from other 3rd
parties.  I can also sell you a Xaar peizoelectric head and controller at
substantially higher price.

According to google HP 45 carts start at $1.96 and go up from there:

The firing pulse generation is under 2us and you need to clock data in/out
at 5mhz on both the rising and falling edges so FPGA solution is easiest but
that's included in my package anyway.
