Silver 8 PCB design

Silver 8 PCB design parameters:

To deliver a controlled DC current to a pair of electrodes @ 1 milliamps using a 24 volt AC or DC power supply. [internal rectifier]

Such that:

1] The polarity switches between the electrodes every ~3 minutes with LEDs showing it is switching [see [url removed, login to view]]

2] A timer is triggered when the current reaches its maximum.

3] The timer can be set in 2 hour increments by multiple pushbutton strokes [1 stroke = 2 hours...2 strokes = 4 hours ] and the timer turns the off machine after the set time.

4] Must be RF interference resistant. [Often used with a DC brush motor close by ] 74HC14 inverter chip to run an H Bridge has proven to be too sensitive.

5] Fit it all on a 2”x2” PCB with 2 mounting holes...surface mount is fine. HAMMOND - 1593KBK - ENCLOSURE, HAND HELD, PLASTIC [url removed, login to view]

6] Supply Gerber files and parts list.

If done using a PIC, can you write the program?
