Thats only part of it Andy. There will be a transistors collector tied to the 36 volt point, pulling it down according the the amplified, inverted output of a MAP, which is a 5 volt device with a very puny output. 100 microamps max. A very old tech called a long tailed pair, useing the base voltage of the right hand transistor to zero out the first 15 psia out of the MAP by holding the left emmitter above cutoff. Not interested in the non-existant vacuum, only the boost the compressors are giving. 2-4 psi will run the mister, or with the liquid pump turned off, will help clear away the sawdust from making the screw. Hopefully without blowing it all over the place. > -- > atp > "A motorcycle is a bicycle with a pandemonium attachment and is > designed for the especial use of mechanical geniuses, daredevils and > lunatics." > — George Fitch, Atlanta Constitution Newspaper, 1912 > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
