Re: Terry's DRSSTC - Class Of Operation?
Original poster: Terry Fritz <teslalist@xxxxxxxxxxxxxxxxxxxxxxx>
It was odd...
Last night I was "working on my DRSSTC". I had the laptop computer,
controller, scope... all spread out over the bed. I was loading programs
into different banks of the controller and checking the output on the
scope*. I worked deep into the night getting it all perfect... Just
"programming stuff"... But those "programs" can vastly and dramatically
change the operation of the coil!! Far more than tuning or fiddling with
the top terminal!!! I tried the controller tonight**, it is "stunning" how
switching a "program" can "change the coil"...
The thought occurred to me that we may soon be pondering the best "program
or algorithm", as the "electrical parts" of our coils fade into
"simplicity"... They used to laugh at us that tried to simply "model"
Tesla coils on computers... Now, the era of the "computer" being the
"heart" of the Tesla coil is almost upon us!!!
It is getting very strange :-))))))))
*very important to double and triple check the programs!!! In one case,
the on pulse time (T1) would roll over from 0uS to 65536 uS as it was
turned down!!! Having the darn thing hang on that long would be "BAD"!! I
added three redundant program checks for that ;-)) I need to add a pulse
output BNC connector to the controller just to help verify the function of
the programs before they are actually run on the coil...
**I was putting up chain link fencing all day so never got the 6000BPS coil
outside (body too wrecked). Robot meeting tomorrow. Shooting for Thursday

You're right about the 6502 in the C64. My brother worked for a software
company in Silicon Valley way back when and wrote many games in assembly
language on that processor for the Commodore. He then went to work for a
modem company writing drivers for the same processor in their modems. Man,
we've come a long way, BABY!!!
All my assembly programming was on the Intel processors in IBM PC's. It's
been so long ago now that I can hardly remember a thing about it. What a
shame. Do you think it is like riding a bike? Maybe if I try, it will all
come back to me! Later.
