Notes:
1.  Dimensions found after the capacitor values correspond to fit SmashTV's layouts 
    (13DIA-5LS=13mm diameter casing with 5mm lead space between holes for the pins)
2.  The required PIC chip (IC1) is not included in this list, 18F452 is available
    blank or pre-programmed from mbhp.coinoptech.com
    or blank from other sources.

PCBs and Kits are available: Click to order.


PCB: (Required jumpers shown in Red here and as dashed lines on the actual PCB)


Construction Tips:

First install your jumpers: (locations shown in Red)

Then resistors:

As you can see with some of the resistor and jumpers, they won't go in
easily after the sockets are installed:
