SpaceX Falcon 9 Iridium Vandenberg Launch
After watching the SpaceX Falcon 9 Iridium launch from Vandenberg last night several times it became apparent that the stage separation resulted in what can only be described as some very strange behavior of the separated stage. I came away with the distinct impression that either this was indeed st...

Re: PREDATOR - valveless PDE build blog
Hi Growlzler, aah, as I understand, you propose to bias a direct current just below the trigger point of the coil? Is that right? This seems to be a very good idea... thanks, I will try...if I got it right? Other ideas? Hi Zono, Yes, biasing the coil is the basic idea. Also applying a short supervo...

Re: PREDATOR - valveless PDE build blog
20 ms action time is a problem.
One idea is to apply a constant current through the coil - the idea is to decrease the mechanical actuation time when full current is applied by the Mosfet triggers. A little experimentation will be needed to reveal the appropriate setpoints.
