The filter is simply a counter that counts up when the G-switch is activated, and counts down to zero when open. If the counter goes over a threshold then a launch is detected. So far the trigger threshold seems to be working fairly well. It samples the G-switch at around 10Khz.<br /><br />I'll post details of the new G2 deployment mechanism once it is tested.George Katzhttps://www.blogger.com/profile/05735356042927822858noreply@blogger.comtag:blogger.com,1999:blog-38795037.post-53335818234466126732011-03-31T18:25:15.332+11:002011-03-31T18:25:15.332+11:00Hi George,

Probably reading consecutive values -on- (e.g. 50-100ms) and see if they are still on for 3-4 readings. <br />You must give some details for new ejection system. Probably you must tweak it a little because it is influencing rocket drag with that gap. At least for G2.<br />Cheers<br />MariusMariusDnoreply@blogger.com
