   A couple more details about my relay-based envelope generators:

   1. Drive the relay coil with an NPN in grounded-emitter configuration,
   or with an open-collector TTL gate, for guaranteed pull-in.

Can you say "inductive kickback"?...

   Do not use 74HCT at 15 volts. I did this, a severly exothermic 
   reaction results. 

...I knew you could.
