Stampers,
Has anyone found a cheaper product that allows a serial number to be
converted into a PWM signal, other than Al's PAK-VIII? I'm not sure, but I
believe that with a D/A chip and a TI PWM chip you might be able to achieve
the same thing. I also believe it would be possible to program a PIC (I
think this is what Al did.) Mine probably would not be as good, however,
would serve my in-house purposes.

I am using one of Al's chips right now. Although I am
really happy with it,
like you I need a more cost effective unit. I am
building these units into a
product which makes the high cost a big deterrence. If
you find anything
else that works, please let me know!!

difficulty. You would need maybe a uart or a shift register and a D/A
converter and some other support chips. Using a PIC with a custom made
program would certainly be an option, but that is what Al did, I think.
If there is enough interest, maybe we can just design one? Thoughts
from the group??

Wouldn't a DAC with a serial input do the job?
David
in "bulk" packaging (that is, no disk or manual). If you need 10 of
the same PAK you should be able to get a discount. Higher numbers can
earn higher discounts as you'd expect.
If you have that kind of quantity needs, feel free to contact me off
list to discuss.
