    new vs. used

    Seals such as O rings are a major factor in this sort of equipment, and obviously need replacing from time to time. You need to make sure that all the maintenace has been carried out by the previous owner, who should have a planned maintenance log to show all if this. However, the price of...

    Switch to PIC to Transmitter Interface

    Thanks for responding, I/P: Analog Compressor. Azimuth is like the bearing on a compass, its a direction, i have to be able to control the bearing of the rocket(Sorry my fault, Naval terminology). I'm using an alpha-numeric display to indicate the bearing and elevation via feedback from the...
