Paypal Shopping Cart

2004-07-19 by grantrichter2001

Since everone seems to like to use Paypal, I've added a Paypal 
shopping cart to the Wiard 1200 series purchase page.

Or at least I think I did. I followed the directions anyway.

Next module is a Frac-Rac version of the Borg filter. Hamamatsu 
has discontinued the Vactrols needed for the Boogie Filter. I 
have a box of 100 of them, but that means I can only build 50 of 
the Boogie Filters. I still want to do the Boogie filter because it is 
hilariously phat, but will do the Borg first for practical reasons.

The Borg is going to be a 4.5" module and contains both a 
Vactrol for smooth sound and an OTA for speed. It will have 
voltage controlled resonance and an OTA output VCA.

The Vactrols do not close off as far as is expected today (about 
-60 dB). There is also a "tail" do to the slow off isolation time. By 
combining the Vactrol with an OTA, we have the best of both 
worlds. Smooth, creamy filtering and acoustic simulation from 
the Vactrol and snappy off time from the OTA.

It is probably not practical to make the VCA completely 
independent. Sorry.
