Well I have the smoke system finally figured out with what I have on hand. Sean I will try the Pressurized method with the start gas when I get a soleniod.

I now have tons of smoke, perhaps to much, on demand. With an O'scope and some experimenting I discovered how Tamjet Smoke pump's speed controller want to be sweet talked. It is no wonder I had a huge delay and intermittant pump action. The speed controller on the pump wants to see low end pulses when you turn it on (approximately 1msec wide). If you turn it on with a much wider pulse or "fast" the controller ignores the pulses and does nothing. If you get the pump running and then switch the pulses off, the pump will run for about 3 seconds (must be waiting for the next pulse and times out). SO instead of setting my speed and turning the pulse on and off, I had to put a 5k resistor on a momentary swtich to my PIC's servo controller. Switch off (1msec pulse) Switch on (1.9msec pulse). This gives me real quick bursts of Smoke... as fast as I can hit the switch and long when I hold it....

To bad the skeeters are all ready dead around here....lol


thanks for all the suggestions...

now to see how the crowd will like eating even more smoke at the drag strip..
